[Q] Acer shuts down randomly

G'day
I am really getting fed up with the randon shutdowns after charging, my tab has never had a uptime of more then 2 days before shutting down. Anyone know what to do about this (besides going for an ipad2 ) ?

I've had this problem since day one (3 weeks ago) I thought I'd fixed it by switching off the GPS but nows its back. I even have trouble booting it as I have to hold the power button on for a few seconds more than once. Do you think we'll be getting a software fix or should I return it?

Mine has same issue, but seems more often since last update!!

not sure if I can help in the shutdown problem.
But regarding the booting/power on thing.... that's how we ALL turns our on....it required a 3-4 seconds holding in the power button

I believe the tablet has an auto shutoff that kicks in after 4-5 hours

Absolutely the same, even after the recent update from acer!

Well, I decided against the Acer, i ordered an Asus.
HC 3.1 is in reach now
Iam really fed up with Acer....what a bull... company.

Not true. I've never experienced this on my A500. The last time it was powered off was when I installed the update, and prior to that it was powered off by me a day or two after it was purchased. I've never come back to the device and had it completely off for no apparent reason.
I use a password login, I keep USB debugging turned on and my wifi is set on when the screen is on, off when not. I charge it every day during the day, and use it at least 2 hours total per day. I have a 32 GB MicroSD card installed.
It sits by my bed with the screen off, and not plugged in at least 9 to 10 hours every night, and it's the first thing I grab when I wake up to check my email accounts and news.
So, trust me, I'd notice if it turned itself off randomly...
I wonder if it's either a software conflict with some people's tablets or if there's a run of bad tablets out there?

I could give you a nightmare story of my Asus EEE netbook...
About 2 weeks before the warranty expired the left mouse button stopped working. I sent a support request through their site and it took them several days to respond. They responded with some initial troubleshooting issues. I sent back that it was definitely hardware and the button didn't even feel right. They took another few days to respond and told me to call the 800 #.
The 800# people had me email them a copy of my sales receipt, which I did. They waited until a day after my warranty expired and told me my warranty was expired and they wouldn't do anything for me.
I tried appealing and everyone ignored me. I'll never buy another Asus product. Previously I purchased around 30 of their motherboards a year for work, not anymore.
That's why I bought the Acer - didn't even have to think twice about it.

I also encounter the shut-down issue. It seems to occur after long periods of charging (say charging overnight). I've had a similar issue with certain ROMs on my Captivate - when the phone would hit 100% while charging it would shut down.
It's a bit annoying, but hasn't been a big issue. If my tablet has been sitting on a charger for 4+ hours it's usually because I don't have an immediate need for it.

Mine also turns off overnight after the update. Hope with next update it works properly and with 3.1.

i never had any problems before but the last 4 days it shut off twice and I notice that it did only after I had it chargin. Is it a really big problem guys? Not for me it takes what 20-25 secs to boot up? I can deal with it till 3.1 rolls out so as long as it doesn't shut off daily while I'm using it idc.

Any news on this problem? I'm almost at the point of returning mine but I think I'll try the factory reset first

just throwing in a me too... just bought my iconia yesterday after returning a galaxy tab 10 (which is THE sexiest tablet ever, but I really needed SD and USB w/o an adapter)... the weird part is everyone else here ties it to charging but mine just did it ten minutes ago and its been off the charger for 12 hours. I also have trouble with the web browser crashing and text selection sometimes is just broken... 3.1 can't come fast enough, and having owned a galaxy tab 10 for a day I can attest that 3.1 is quite a bit better.

i've had mine for nearly a month now, and it's only just started shutting down automatically last night. Happened a few times consecutively last night, and it's happened again about 10minutes ago when i just went to use it it was off, and i distinctly remember it still being on after i took it off charge this morning and put it in my bag.
Starting to become a little annoying especially if it continues to get worse.

Browsers shutting down for some sites. Java problem ?
+ 1
Its meanwhile a month ago since the last posting. Is a solution found ?
I use Dolphin 6.0.0 on Android 3.01 1.141.01 and for month's it worked perfect.
Today, it starts shutting down for some sites and indeed switching off java solves the problem. Same for stock browser. Its annoying that this happens without a clear trigger because it indicates an unstable system !
edit: sorry, wrong thread

just picked mine up yesterday and encountered this last night. Which is especially annoying since it was halfway through downloading the 350MB update when I went to bed.

So update to 3.1 - the official version has been out for over a month now, it is a lot more stable then 3.01 in my experience when it comes to web browsing. Just copy the correct update.zip to microsd, reboot with top vol rocker/power held, you got 3.1 without waiting for Acer to push ota to you.

Transformer + Dock = Amazing

Just got my dock today and all I have to say is, wow. This is one helluva sweet device now. The functionality of both touch screen and keyboard rock!
I love the extra expansion, it's crazy how how much extra you get with the dock. I can now have the 16g onboard + 16gig micro sd plugged into tablet and 16g Sd plugged into dock. That's one helluva lot of storage for a tablet and for the price, it's outstanding. Add the two USB connections and it rules. Looks damn good too.
Great job Asus. Love my xformer

Ya it'd own even more if they fix the 4% per hour battery drain on the dock when the tablet is docked and it's sleeping.

Man, it never ceases to amaze me how many people just want to whinge on this forum. Just plain amazing - now go back to the dock-battery thread.
Love my dock too - use the tab about 6 hours a day, charge the tablet every or every second day, but it is fantastic when out and about. Last Sunday was out and about without access to Internet or computers for 12 hours - but my trusty TF brought me season 3 of "The Big Band Theory" to keep me entertained!

Maybe yours is an early version or defective, mine doesn't drain like that. I've had no charging issues. The keyboard will always charge the Transformer unless it is fully charged and use the keyboard battery first, if the Transformer is using WiFi or GPS it will drain the keyboard.

absolutely agree with OP. Fantastic device, even if it does have a few quirks. I wish the root development scene was moving a little further, cause there is alot of potential for this thing!

Actually, I don't think that'll be an issue. I have the newer dock model (B60KAS) and from what I've read/seen there is no drain.

I'm starting to wish I were an affiliate, I've sold three people on them and they're all very pleased.

Me and my eee pad plus dock have now, reached an understanding, it is a truly amazing device when coupled with the dock, as an avid fan of android from launch and the owner of an original I pad, I have now realised that all my gripes are based on comparison with the I pad. OK it does have a few little annoyances, but on the whole after a month of use, this thing seems to be getting better by the day. I think Asus are bang on the money with the TF. The screen is superb and build quality better than most high end laptops. I agree with earlier comments about the negatives played against the TF being over the top, I myself was of the original wingers. But everything it does that works OK, it does brilliantly, and im sure the rest will follow.

So do you think it is hardware related? Would be a bummer, I still hope this is fixable with a firmware upgrade for the dock

Ordered my dock yesterday, will hopefully get it tomorrow.
Really looking forward to it after reading this thread

Yes, dock is really great.
I charge my TF once a day (during the night) and could work a whole day of meetings, mail replying and browsing without to be worried of battery lack.
However, I think the battery time could be better (perhaps, Prime 1.5 combined with 1.5 Ghz kernel is the cause), seems to be better when I was with stock system. The Dock also provide a very convenient way to type texts, etc... without transporting my portable PC.
A very good investment (even somes think it's not really necessary) on my side.

You are easily impressed. LOL!!!
It is a neat little device....but there will always be something newer....but not necessarily better.
I do however, love the expansion options made available to us with the dock.

Not sure, I just finished reading further and I guess some people on even the same model as mine have the issue. I'll keep an eye on things and see how it goes. Not sure if it'll be an issue or not, I will update later.

I own a b50kas and have no drain, others have, nobody even knows whether it is a defective tablet or dock that causes the problem, how many tablets docks are affected ? Maybe only a few, if i would have this problem i would rma both tablet and dock.

I was pretty sure everybody has this battery drain issue but now seeing some peeps come out of the woodwork just today claiming they don't. Now I didn't notice this battery drain issue until other users started mentioning it so then I paid closer attention to it, well that plus somebody put out a battery widget that showed you the dock level whereas before I didn't have a way to check. I have not shut my Transformer off while docked and let it sit to see if it then doesn't drain, if it doesn't then I suspect it's possible some of us including myself have some app running (maybe the dual battery widget?) that's causing it. I shall try this tonight.

I think the reason that a few don't see the draining is that they using the combo with a transformers at 100%. Because i doing it right now and i don't see the problem. So everybody with the problem should charge both to 100% and testing it.

No as I stated my tablet is always at 100% and I have this issue, I actually just leave mine docked all the time and when I put it up for example when I leave for work, or go to bed, my tablet is 100% and the dock may be anywhere from 30% to 96% and this issue happens, so it has nothing to do with not having it at 100% when you dock it.
I wonder, does everybody here use a dual battery widget? I've always wondered if maybe the widget itself is the cause, liek it' spinging the dock for battery level all the time. Would be interesting to see if we say charge everything up to 100%, uninstall the battery widget and reboot just to ensure it's gone and not left running, then let it sit idle and reinstall it later and recheck. I may do this tonight/tomorrow and see.

I agree. I ordered the dock with mine when I got it and haven't looked back. I use it with the dock probably 90% of the time. Its a good mix of function and form for my use. This device pretty much replaced a laptop/netbook/tablet for me. Combined with a WiFi hotspot from my Inspire 4G this thing rocks.

Cool
Just got the evo3d and wish there was something like this for it,

[Q] buying a used transformer?

A friend of mine just bought a new Transformer Prime and is looking to unload his current one. He offered me a price of $250, and that includes the KB dock and necessary accessories. Seems like a decent price with the dock.
I have been reading up about the device, and discovered that the KB and the tab have their own batteries. Are these user replacable? If not, how much do these cost to get replaced? From my own experience, these Li-Ion batteries only seem to last a year or so in phones, so I don't expect much better than that from either of these, and will probably need to replace them soon.
Also, I've seen a lot of talk about random reboots. Are these generally hardware related issues, or is everyone just back to running buggy roms because they have that need for ICS? $250 is too much for me for a device with random reboots.
Also interesting to note... a friend of mine with an Atrix has been plagued with random reboot problems as well, so perhaps this is a Tegra 2 thing? If anyone who has been around this forum for a while would care to provide some insight.
Thanks.

To answer as objectively as possible:
Batteries: Non-user replaceable
Battery life: I have had my TF for nearly 1 year and the battery still works for a good 7-8 hours before needing juice
Random Reboots: This is an issue that surfaced after the latest ICS update from ASUS. ASUS has identified it an a fix is expected next week according their announcement.
Would be happy to answer any other questions you have.

They are lithium polymer batteries, they aren't replaceable, i wouldn't worry about the batteries
The tegra2 drivers are causing the reboots BTW, thanx for the info on the atrix.

Thanks for the quick, and to the point answers! I was mainly concerned with the batteries due to the issues I have been reading about with the keyboard dock and power drain (in combination with their usually short life expectancy). I take it from your comments that the keyboard dock power issues have been completely resolved by ASUS at this point?

No...But are you not going to root it? I reverted back to Honeycomb. Smooth. Overclock. Batteries last forever.
Asus hasn't released anything. It was posted on a facebook page that they plan to? Take that for a fix soon.

Thanks everyone, ended up buying the Transformer so you guys will likely see me around here a bit more often.
The keyboard dock is very nice, and I love the way it trickle charges the tablet to keep it full throughout the day. Haven't been able to kill the tablet over the course of a day, so I have to say I'm ecstatic about the battery life.
Already flashing new roms and testing out new features (such as cornerstone).

To add to your question, I am also buying used Transformer. Is there anything I should check before buying on Craigslist? Like light bleeding, color, Serial number?

@metaldood if you want to buy used transformer and live in USA i advice you to check also amazom.com they have good prices but couldn't take it there 'cause i'm in italyand after shipment and taxes the price is like the new ones here.
however i purchased mine with dock for 350 euro

ICS problem solved. Best of luck to everyone else.

Update - After 2 months I couldn't take it any more so I sold it and actually got a rating of "good". The other solution involved a sledge hammer. I can't believe they didn't notice the 1 hour battery life. More proof that quality control worldwide is going down hill. Apologies to who ever gets mine as a refurbished unit or parts from it.
Screenshots
http://forum.xda-developers.com/album.php?albumid=6825
Battery Life from 100% to 0%
ICS .11 & .17 - 6 to 8 minutes (Pic 1)
ICS .21 - 35 to 52 minutes (Pic 5)
ICS .24 - 50 to 65 minutes (Pic 11)
Bug count
RR & Boot Loop - once on may 14th after 2 months on ICS
Battery meter stuck at 100% - 4 times
Irregular charge and discharge cycles - lost count
Battery meter continues to go up a few % after charger is unplugged - lost count
Screen flickered - 8 times
Screen unresponsive / no input - 11 times
No sound what so ever - once
Irregular charging ping sound - lost count
ICS .24 - Finally got over 1 whole hour of battery life from a full charge.
ICS .21 - Since the 9.2.1.21 update I had it 4 times total, it's been alternating with another bug where it goes from charged to zero battery and shuts down the second I unplug the charger. The infinite power bug must only be triggered by OTA update because I tried reinstalling the .21 firmware. The zero battery "bug" could be the result of the infinite power bug allowing the tablet to actually stay on long enough to completely drain the battery. Since .11 update the charging ping sometimes stutters and sometimes plays half a ping and stops. Just had a new bug of no charging ping. The tablet and the sound was on at the time. Battery was at 82% and icon changed to charge mode but no ping sound.
ICS .11&.17 - battery drain from 100% to 0% in about 7 mins and charges up in about the same amount of time. Had this bug for over a month from march onwards. I first got the infinite power bug after upgrading to ICS, it's where the battery meter stays at 100% for hours on end without being plugged in for charging.
My TF101 is from the B30 batch.
I do not have the dock.
I haven't used the camera since HC and I just noticed there is dust on the INSIDE of my case after the "repair". There's no way to clean it except to open it myself. The trim is also now separating a bit from the main body on the top left and bottom left. When I got it back from the repair center it was just a little on the left side only.
Things I have tried
Downgrading to HC, but method was very old and likely not a complete downgrade as it did not work. Battery status wipe, Reboots, factory data resets, cold boots, changing various settings, etc. I sent it in for repair which was a waste of shipping costs. Emailed ASUS twice, response time is longer than 1 week. Calling is much faster but same results no one knew if it was hardware or software problem. After sending it in for repair the left side of my TF101 looks like it had been spudged open so they could have already check the hardware. Dragging around a 12FT extension cord is still currently the best solution I've come up with.

Thanks for making a dedicated thread!
Suggestion: Throw a couple more keywords in the title to help others find it. Eg: based on your symptoms, maybe add something like "battery meter issues, shutdown when unplugged from charger" or something similar.

did you try wiping the device?

I managed to pre order my TF101 a full week before the official release date. Now it's come back to bite me in the rear end cause my warranty is up today. I have the service number and RMA from march so maybe they will still honor it if it turns out to be a hardware issue.

Yep. Have you tried doing a reset and supplying a brand-new Google account, so that it doesn't immediately copy any old data to the tablet? (Or even just not supplying an account or connecting to WiFi / Bluetooth at all, so it's 100% stock)?
Has it ever had a custom ROM or been rooted?

The bug occurs even if no account is entered. Wifi, gps, bluetooth on or off it still happens. I had it rooted to overclock on android 3.2.1 I rolled back to 3.0.1 to unroot and get ICS, quite regretting that decision as it ran fine except for a few browser crashes which doesn't seem like a big deal now. I also tried downgrading to 3.0.1 from ICS, still had the bugs. It's running stock ICS right now and the browser rarely ever crashes.

did you try up up down down left right left right b a start?
Sorry, couldn't resist....

How did you downgrade? It's my understanding that some methods leave the kernel Asus shipped with ICS in place, and hence aren't truly 100% downgrading...

That's most likely why it didn't work. I had the link to that guide saved but since it didn't work I deleted it. I'll have to wait for an official release or a better more complete method of downgrading.

I had a similar issue with my phone at one point. I went into cwm and wiped battery stats and it seemed to clear my problem up. I'm sure if it would work in this instance but it couldn't hurt to try.

I really don't think this is an ICS issue as you are the only one reporting it (that I've seen). Sounds more like a hardware problem to me....

I have sent it in for repair, no change. The left side looks spudged open so they could have checked, but no one can tell me if they actually did check the hardware. They ask me to send it back for repair again. If they did replace it with andother TF101 it could be a refurbished one that has other kinds of bugs and be scratched and in worse condition than mine. If they gave me a brand new one it could also still have these or other issues. I am waiting on official or better unofficial way to downgrade to HC.

If anyone knows more about the hardware for the TF101 please post your thoughts on what could be going on with these bugs.

Could your battery not just be simply shagged?

A few days before ICS update I had 7 hours of use out of one full charge. I always shut down instead of sleep. Normal battery life is usually 6 and half to 7 hours and 15 mins. The combined total hours of use during the 100% power bugs after .21 was 4-5. If it is really the battery then ASUS is the stingiest company in the world cause they should have replaced it at the repair center when I sent it in.

has anyone suggested to clear your battery stats in clockworkmod (assuming you have it)

Massive battery drain when in sleep mode

I just posted a very positive review of the TF300 today and just got back home after being at work for ten hours. I left the dock and tablet at over 95%, but just got home to find the dock at 0% and the tablet at 46%. This is obviously awful and makes the Toshiba Excite seem great in comparison.
Settings:
MobileDock battery saving mode is on
Disconnect network during sleep is on
Set to balanced mode
Set to turn off after two minutes
I turned the tablet off before I closed to the dock and when just opened the display was off.
The only two listings are 64% for screen and 36% for idle.
Is this normal? If so, this is abnormal.

weird, i don't recall that ever happening to me... try it again, charge it to %100 and leave it on sleep mode at night and check in the morning if the problem persists. if so you may have a defective unit so return it using your warranty.

Another thing I notice is at least in Dolphin, the browser crashes when trying to view Flash video in full screen. I have never had that happen with any tablet or phone before. Weird. Like always, set in desktop mode for user agent.
Edit: Must have been a fluke since a restart fixed it. need to charge now anyway to see if I get the drain again.

I noticed if you turn off the tablet then dock it, the tablet will turn back on. But have never noticed a battery loss that significant. So be sure to dock the tablet first then power down the tablet.

I've had mine for over a month now. Had something similar happen one time. Best I could figure out was ICS did not properly shut down a game I had running. I assume it was just a rare random occurence.

Another thing I notice is at least in Dolphin, the browser crashes when trying to view Flash video in full screen. I have never had that happen with any tablet or phone before. Weird. Like always, set in desktop mode for user agent.
Edit: Must have been a fluke since a restart fixed it. need to charge now anyway to see if I get the drain again.

You should check out the new dolphin beta that just came out today, supposedly wickedly fast. It is here: http://dolphin-browser.com/2012/06/dolphin-browser-is-the-fastest-html5-mobile-browser-try-out-our-dolphin-engine-in-beta/

It did it again last night:
Made sure no apps were pushing data and turned notifications off for all apps
Restarted the device and opened no apps
Five minutes later I put the device to sleep (closed it).
The display was off
Result: This morning the dock was dead and the tablet was at 65%. This was after only six and a half hours (I usually do not sleep much).
The only activity was the display at 84% and idle at 16%. I checked a few times through the seam of where the KB and tablet are closed and the display was off for thirty minutes before went to sleep. I then had to get up a few hours later to let my dog out and the display was still off.
The last time I had problems like this was the infamous A500 problems where the display would come on, stay on and the device would die. In this case, the display is not coming on, yet the display is eating the battery and the device is warm (dock and tablet). The A500 was obvious, since the display was on.
Folks, I just want something to work correctly. My HTC View loses 5% over three days and my iPad 3 wifi loses 1%.
How can the display be off, yet the device be warm and the battery log show the display is the majority of the usage? No doubt the display was off (at least at the times I checked).

The display is the majority of the usage period. When in normal yesterday with 100% brightness the display used 99% of my battery use. That extra 1% was for the dozen or so apps I had used. The fact that the idle hit that high is a good thing but something else may be affecting it.
Have you tried disconnecting the tablet from the dock and then letting it sleep?

That is my next test, but if they can not behave together, the value of having the TF300 diminishes. I would need to keep them is need to leave seperate, since defeats the function for me.
I see the point in at least testing to see if the dock is the issue. Could be a bum unit, but also could be the dock does not like cards being left in.

My tf300t works amazingly without any battery problems.. I'm a very heavy user of it. also try getting that app that monitors background/network process...forgot name if someone could help. Also the dock could be at fault since the dock automatically turns on the tf300t same as if you would charge it with the cable it turns it on while charging.
I believe the build.prop mod contains something about deep sleep that might help ya but if ur in the 30 days just replace it why bother when u might have an intermittent defective unit . problems that can happen once in a while might be a pain in the ass later on.
I do not regret choosing this tablet over everything else on the market it works great and it is replacing a laptop for me.

I've had no problems with the battery on my tf300. It lasts all day when I use it (and because it's new I'm giving it some heavy use) and when I do need to charge it it only takes an hour or two. Maybe because you just close it something doesn't shut off. I don't own the dock.... Yet but when I do I think the extra life out of that will be awesome. On a second thought I was also wondering what would happen if you just left it on the charger overnight? I put my phone in a dock to make it my alarm clock every night with no problems. Is a tablets battery different that it wouldn't be healthy for it to be left on the charger? Or does it needs to fully drain then charge to 100%?

I agree it is nice system so hope I figure it out. My Office Max dock should be in soon, so have to return this dock anyway. OM was $100 (sale) and BB is $150. BB matched the OM price on the tablet ($350), but the dock was not in stock at OM. Ended up ordering one online from them.

I normally do leave it on charger but it is problematic when away from home, since uses as much battery as when on. Not to mention it can not be doing the batteries any good.

For process of elimination I tested the battery drain with the sdxc card out of the dock. This seems to help, but still have over 20% battery drain (a lot less, but still bad).
Next step is the tablet on its own and then I will test with my newer dock, since just came in from Office Max (need to return the $150 one to Best Buy). Hoping the dock was the issue since if the dock and tablet can not behave together, I will return them and not dwell on it anymore.
Hoping the drain is gone so can keep Having the sd card, micro sd and 32gb internal solves all my gaming and media needs, but need the batteries to not bleed out when should be asleep (not practical to travel with- as is).

Aftera few full cycles i notice battery depletion much slower also I keep the tablet in balance and performance when gaming things like nova 3 and tegra stuff etc. And around 25-30% brightness is more than enough indoor . My battery last me all day on 1 charge including the dock wich it charges arund 60-65% extra battery. This are just estimates through my experience with it not concrete data.

I have 40 more days to return the tablet with Best Buy, so want to see what the issue may be and avoid resinstalling everything and setting up if can avoid it.
I really like the tablet and also that it is not clocked higher (better for heat and battery). It plays N64, PSX and MAME Reloaded fine. Ditto for Flash and hidef video content. Touch response is as good as my iPad 3 and former Toshiba Excite.
Also, for $350 the tablet is REALLY nice. Not wanting to paying much more, since already have a 64gb iPad 3 (2X the cost of the Asus). I mainly use Android tabs for Flash sites that do not work on the iPad (Amazon Prime is example) and game emulators. Heck, even books and comics look sweet on the 300
Along with the dock, the 300 makes a GREAT mini-system for games and media
Besides, I am not a fan of 1920X1200 displays being pushed by the Tegra 3 and no gpu modification. The chips sweet spot is 1280X800. My iPad 3 rocks with hi res but has a bigger gpu to support it.
Update: Even with the new dock the batteries are sucking dry. 20% gone in a little over an hour. It is like the display is on, based on the drain.
Will test tonight with just tablet, since same result with two docks.

I hate to ask this because it's seems so obvious & condescending - but what have you installed? Did you try doing a factory reset? I've had 5 android phones and few times I've loaded some obscure piece of software that killed the battery. I've even loaded ROMs that sucked the battery down with no mods.
I ask because I just got my TF300 yesterday and played with it all night without charging it. I did the 4.0.30 OTA update as soon as it booted up. I let the keyboard completely die and left the tablet (undocked) this morning with 56% on it. I didn't put either on the charger because I want to see roughly how long it will run without doing so. I'm hoping I have no problems such as yours, but I'm watching this thread closely.

Ok, so you know what my usage is - Like I said, I left this morning (6:30) with the keyboard dock battery dead & the tablet battery at 56%. I got home this evening (5:00) and the tablet was at 53%.
Luckily I'm not seeing the problem you are (though I haven't tried to charge the keyboard yet), but at least you have a warranty to fall back on.
