Is anyone having this problem. I have an a70 250gb when I push the power button it stays lit even in deep sleep. My battery drains completely overnight. I don't want to power off when not using for short periods of time.
I had the same bug as well with my 25ogb, but for some reason after a full reset it seems to be gone...
I thought at fist a program might have caused it, but i've reinstalled the same apps and i don't have this problem anymore..
I too recently developed this problem where the LED light stays on and keeps using power when in standby. I thought it might be some app I'd installed but thought it might sort itself out so after a week without improvement, I did a Reset, without result (except for losing another 32MB to the Swapfile). So then did a Reinitialise, also without result. To be clear, I didn't install any apps and still the thing won't go to sleep anymore. Any idea's?
Well looks like we're at a loss... I got the same bug on my a101. Battery drain isn't too serious though, but still it just boggles the mind.

I have the same problem and it happened around the same time my USB port died.
I've been waiting until the shop where I bought it has stock again to return it for repair/replacement. I think this is related to the USB dying.
It's happening the same with my 101. The led stays on when it goes to sleep, even after stopping all the processes using the Archos OS Monitor tool.
After a reboot seems to work OK; the led turns off in standby mode after five seconds more or less.
I haven't used deep sleep yet.
Maybe some application is causing this?
I installed only a few apps and firmware is v2.1.08:
- Aldiko
- Angry Birds (of course)
- DroidWall
- ES File Explorer
- Google AppsWidgetsoid
- SiMi Folder
- Zuma's Revenge

Have you checked the right tab "Wake locks" in the Archos OS Monitor?
Yes, I did change to this tab once and the list was empty. It appeared and disappeared a process very fast, so fast that I couldn't read the complete name
Good hint!
I get this sometimes on my 101, but a reboot seems to sort it out, Its got to be a process or app running in the background I think.
The best answer on the ArchosFans forum was :
My gut reaction is that you'll see this happen when you have the USB host problem because that issue happens when the power regulator chip in the Archos dies. And nothing can be done other than an RMA with Archos.

I verified this and my USB port was indeed not responding, so I've swapped it at the store and the new unit is wicked
Re: Power Button Staying Lit (Possible Fix)
Ok here's what I did after checking that the USB port was not the issue(worked fine with a usb flash drive). Check the following location
Go to: Settings-->Location & Security-->Use Wireless Networks
Description lists it as "See location in applications(such as Maps) using wireless networks)
If it is enabled, disable it. I turned it off, went pack to my home screen Soft press the Power Button for Standby Mode and the power LED is off within a few seconds.
Worked for me, Hope it works for you
Yeah, I have the USB host problem too, and it does seem like that is the cause. Argh, I don't want to go a week without my A70. D:

Confirmed. Hell, didn't know that would work O_O.
Thanks!
No luck for me - it was already off, and toggling it on then off didn't help, even after a reboot.
Nothing in the wake-locks list, and my host USB port is dead.
I see an RMA coming.
*Please be aware that if you have rooted your device you may get undesirable results from daily use that I haven't covered here. That is a risk you take or something you have to put up with or solve/workaround yourself, or with your rom provider.*

Have a problem with your dock/battery?
Read THIS first.
My FOTA update keeps failing to install.
You have to fully return your device to stock (not just unroot). Use NVflash to do this. Then go to the asus ftp server and download any update file. Update your device using that file and this should allow your device to update FOTA properly.
Get a tingling sensation when plugging in a charger?
Flip the charger over and plug it into the wall so that the S in asus is on the side with the fat slot on the plug to fix. Seems to be a faulty adapter issue.
My screen isn't displaying anything:
Make sure none of the side buttons are stuck. Press them and make sure they 'click' ok. Force power off your device (10-12 second hold of power button, then release). Wait for about 30 secs. Then power it on normally (6sec power button hold and release). If your screen worked, then stopped, try discharging the battery to 0%. Then re-charging it. This has seemed to clear screen responsiveness for lots of people.
My dock battery is dead and it won't start to re-charge:
Try this tip HERE.
My speaker volume is stuck at a certain level:
Force power off your device (10-12 second hold of power button, then release). Then wait for about 30 secs. Then power it on normally (6sec power button hold and release).
My device/dock battery isn't charging OR my device/dock battery isn't holding a charge:
Make sure the charger is 100% clipped together properly. It's a very tight fit and may need slight force to snap together. Also make sure you have inserted the usb cable the right way up in your adapter. Sometimes unclipping, and re-attaching the adapter parts fixes problems (some come pre-assembled already so this may not be your issue). If your dock battery indicator doesn't ever go green after about 8hrs of charging (not for the first charge) then it may need RMA'ing. A normal charge of the tablet itself, from empty to full, should take about 3hrs maximum (not for the first charge).
My battery is draining very quickly:
Some apps run fine in the background, but there are others that may be 'keeping alive' certain functions, such as gps, sensors, etc. In order to get around this you can use free task killing apps from the market. It's recommended to be selective about which apps you choose to auto-kill. Don't just put them all on auto-kill (unless you are using a 'safe' option in the app) or your system may become unstable. If you have wifi on when you put the tablet in standby, it stays connected. If you then leave the network coverage area, the tablet will continually search for any network around it, draining the battery further. So when leaving home, remember to switch it off. Another possible cause of major battery drain is a badly coded/incompatible app. Get a battery monitoring app from the market and keep a close eye on the logs it produces. Don't watch every little blip/spike in the readings, try to take an average reading, over a few hours/days to get a better idea of what's happening.
Why isn't my device charging when I plug it into my pc?
It will only charge when the display of the device is off. And it is extremely slow and will only trickle charge. There are ways to boost power to your usb port, but the risks far outweigh any benefits.
My keyboard dock has X issue:
The next firmware update should solve many dock problems.
My touchscreen isn't working properly:
A future firmware update may resolve this issue.
My speaker balance is off (louder/quieter in one speaker than the other):
A future firmware update may resolve this issue. Or if you don't want to wait you can read THIS thread.
My X app force closes/crashes unexpectedly:
Check with the app developer/market for an updated version compatible with honeycomb.
The default camera app is showing a green screen:
This was fixed in firmware update1. Upgrade your firmware.
I don't have MyCloud or splashtop apps installed. Where are they?
These were added in firmware update1. Upgrade your firmware.
My email widget isn't updating and always shows 0 emails:
This was fixed in firmware update1. Upgrade your firmware. Then remove the widget from your home screen, reboot and then re-add the widget to your screen.
My wifi signal keeps dropping:
Update to the latest firmware. Set your router/modem to a specific channel (set it to 1-11, NOT channel 12 or 13). Failing that, it's probably time to buy a newer wireless N router/modem (the TF does not support 5ghz, only 2.4ghz).
One of my speakers stays on even when nothing is playing from it:
Put your device into standby mode for 5+ seconds. Then turn on again.
My charging cable is too short:
Some 3rd party USB 3.0 male to female extension cables work to extend the length. This seems to be the luck of the draw if it works for you or not.
I get horrible movie recording framerate issues:
This was fixed in firmware update1. Upgrade your firmware.
My microsd card isnt working:
Make sure it is formatted to fat32. Make sure it's securely fixed into the slot. It has to be pushed in quite a way. Use a long fingernail or the edge of a credit card. Make sure it clicks and holds in the slot. It should be flush to the side of the device.
I have dust under my screen or dead pixels or both:
Return and replace for a new unit by RMA'ing your device.
My MKV video playback is jerky/unwatchable/not working:
Make sure it's a low profile encoded file.
My device isn't powering on:
Perhaps you have put it into APX/nvflash mode by mistake (which doesn't display anything onscreen). Force power off your device (10-12 second hold of power button, then release). Then wait for about 30 secs. Then power it on normally (2sec power button hold and release). If still nothing you might have to RMA it for a replacement.
I can't install any apps from the market:
If you are in an unsupported country you can try THIS. If you're not and still can't install, sometimes google does maintenance that affects certain accounts. Try it again at a later time/date.
My onscreen keyboard is laggy:
Change the keyboard from the default Asus keyboard for the stock honeycomb one. Turn off text prediction. If still laggy you have a conflicting app. If fixed then find another keyboard app that you like.
When I plug my device into my pc I cant transfer any files:
Make sure the device's screen is on, and that the lockscreen is not showing.
My dock isn't charging my tablet above 97%:
There is inbuilt code to stop your device from charging above a certain point to prolong the battery life.

My SDXC card isn't working:
Format it as NTFS, if you are using files over 4gb on it or the card wont work properly. An alternative method is to format the card as Fat32 filesystem (if you are going to be only storing files under 4gb in size), but you will need to partition it into 32gb sections if you use this formatting system, for the full capacity to be usable.

My battery died very quickly while the tablet was in standby:
If you have wifi on when you put the tablet in standby, it stays connected. If you leave an area of wifi coverage, the tablet will continually search for a network, draining the battery.

You can modify that behavior in the wifi settings. Take a look at the sleep settngs.
I have not seen this mentioned so it probably is not too common a problem but my wifi was initially invisible to my transformer. Switching the channel from 13 or maybe 14 to something lower fixed the issue.

Yes, and I want to stress: wifi performance on standby is problematic and needs a fix. On the Xoom, wifi can be kept on when the screen turns off and standby performance is in the <.5%/hour battery use range. The Asus needs to have wifi set to turn off when the screen is off to achieve this kind of performance (otherwise, it burns about 3%/hour).
I'm hoping Asus is aware of this issue and will fix it soon in a firmware update.
some very good points, thank you
Touch screen stopped responding to touch
Brand new unit after about an hours use the touchscreen stopped responding to touch. It did this on Friday, May 13th, between Noon and 5pm eastern DST. The unit was working when shut of and was in a safe spot. I went to turn it on and no touchscreen. I noted the time as I think there may have been an OTA update then but I never saw anything on screen.
No monkey business, rooting, tinkering etc. Just learning about unit.
I have wiped the memory and cold booted several times, no change. I note that after a forced off the unit turns back on by its self. I saw earlier when I started the browser for the first time, the right 25% of the screen was over bright then went dark. Exiting browser, screen returned to normal and never saw this behavior again.
Screen may be somewhat dim now but cannot get past setup screen as only power key is responded to.
Already asked B&H for RMA but any magic gratefully accepted.
Howard
@easyrotor
Unfortunately it sounds like a clear case of a faulty unit. Don't know of anything that can help in that situation im afraid. Not what you'd want to hear of course, but at least it should be a simple exchange for a new one.

- On this note, does it only apply to Dock-to-Tablet charging or also for PSU-to-Tablet charging?
- I have not try the dock to see it for myself but at least with PSU, it seems to charge my tablet all the way to 100%.

Good point, I'm not sure. I assuming that no matter what, the led on the keyboard dock would show just it's own charge.
Will have to monitor it for a bit and get back to you.
Hopefully later once Asus release another update, it will contain the dock battery vs. tablet battery (that got taken out from the .12 beta build) for us to monitor both.
just wanted to say that this thread is awesome...thanks so much for putting in the effort to document all problems/solutions that may come up with our TF's.
It might be worth mentioning light bleed here?

Transformer won't Charge
I received my eee pad transformer from hh gregg yesterday. When I opened the box I noticed that there was a scratch that appeared to be under the the screen. The scratch is very long, but also very fine and you can only see it when the screen is dark and you hold it up to the light. So I figured what the heck, not that big of a deal. However, when I went to charge the transformer, I cannot get it to charge. No light, no nothing. I've tried everything. Plugging it up to the computer, plugging into the wall, taking apart and putting back together, still nothing. I'm trying to figure out what to do. Does anyone know what could be causing this? Asus said I can send to them and they will look at it or I can send it back to the store, however, the store does not have anymore of the transformers in stock.

If you are taking apart and putting back together the wall charger then you likely haven't put it together properly yet; it will not come apart easily at all if it is fully together.
Try pushing harder than you think you should until the pronged portion is snapped in to place and you cannot easily remove it again. If it doesn't snap down, the contacts on the back side don't line up and it won't charge.
Hey guys,
A friend of mine recently bought this tablet and everything was running very very smooth, until he received the OTA to 3.1 . Besides the wifi bug ( very easy to get rid of ), he is now experiencing a really really weird touch lag. Let me explain: as soon as he plugs the tablet in the charger the touch gets really unresponsive forcing him to slide/touch several times before the tablet detects the input even if the system keeps working as it should, ie no slowdowns etc.
Funny things is this bug only shows up (for now) when he plugs the charger in university while not happening at home.
Has anyone experienced the same? Im starting to think that the charger plug has a defect and is in some way affecting the touch system ( electric\magnetic stuff ) leading this to an hardware related problem, but I want to be sure so maybe we will try to flash something (Are there Acer tools to flash full stock roms?). Tablet is running original rom and recovery, I just messed with the wpa_supplicant files but I dont see how this could be related.
Thanks in advance guys
When my screen is off and I turn it back on when I switch from charger to battery I get laggie for a minute. Same on my notebook and my cell.I believe its to do with changing some power profiles/settings. If you recover in a minute or so its prob fine. If not watch running apps. If you see something running all the time.use a freeze program to trouble shoot if its a rouge app.
Hope this helps to troubleshoot your isssue
If im wrong with this information please just give your correct response to the open. Do not bash my openion.thanks

110 volts

When you plug your charger in the fram becomes hot. 110 volts to earth. Just check it, can't be good.

Fram? 110 volts? What are you talking about?
More details - please. "110 volts to earth"? Not making much sense.
My guess, and its just a guess, is that his charger is somewhat faulty and not regulating the power correctly. Ask him if he plugs straight to the wall at university and into a power strip/surge protector at home. If he is, then I would imagine that the power strip is regulating the voltage enough to let the charger work, where the wall outlet is making the charger fail. I'd try a new charger if one is available and see if that fixes the issue...or take a surge protector with him to university and see if that also takes care of it. If he isn't using a power strip at either place, then we are back at square one.
Have you tried going back to an unmodded system to see if that works? (by that I mean remove/undo wpa supplicant).
I have no idea what that problem could be as it seems hardware based by just reading what you typed, but it could be software too which is called into question by the little mod you did.
What I find odd is that it works in one place and not another.
Does it happen when Wifi is off completely? (Just asking because I'm thinking if it has to do with the wifi mod you made, perhaps turning Wifi off and testing would show up something).
I'll just tell you what I would try in that situation.
1. Go back to a stock ROM, fully. No mods, no root, no hacks. Preferably one designed for your region. (We have no idea if any of the hardware in these units is different based on region, which is why I never recommend putting a ROM on the device unless it's 100% certified to be originated from a device purchased within that region).
2. Factory reset. (It doesn't fix everything, but it fixes most software glitches - especially when they're caused by outside sources like apps or settings mess ups).
If it still happens after that then you've at least ruled out all software suspects.
The frame of the a500 is hot. The charger is none polorized so makes no difference which way you plug it into the wall or extention plug is the same. Check your charger to earth and you will see line voltage no mater where it's pluged in, and don't have to be pluged into the a500. They need replaced. Just meter from the outside of the charger plug to ground and you will see the problem. Might not be on all chargers, but I would check mine.
Just check you charger plug to earth without the a500 pluged in, the problem is not in the unit or software just the charger.

I had an issue like this with a palm pre, and the only solution i could determine was that i was using an offbrand charger that wasn't supplying the right voltage/amperage and causing flakiness with the electrical charge on the screen. maybe the charger is damaged, or they're using an off-brand one?
Ty guys and sorry for the late reply. Yeah I was thinking about reverting back to the stock system but unfortunately I'm not very familiar with the tablet scene not having one and since he is a little frustrated atm about his situation maybe flashing a recovery to flash a stock rom isnt really the way to go. Isn't Acer delivering any tool to flash a full rom just to try if that will solve the problem?
Thanks again!
So wait someone is getting 110v from ground to the metal frame of the tablet?

Same issue
I found this thread, and this is exactly what's happening to my tablet. When it's plugged in, the screen becomes very unresponsive, and it's very annoying. I can't charge it and use it at the same time. It's not even like galaxy tab 10.1 or ipad 2 where the battery life lasts like 10 hours! I am extremely frustrated about this issue..Mine has this issue at home. I don't bring charger to school, so I don't know about that. I'm really surprised that only very few people actually have this issue..
electrical grounding no good
Anyone has a solution to this?? Should I buy a new charger? I don't want to just waste money if it's not gonna fix the problem.
Thanks.
I had a similar experience to all of this when I was recently travelling by airplane. There were charging outlets (US-style 2-prong) on the back of each seat and my tablet absolutely REFUSED to respond properly to touch when I plugged it in. At the airport, in the hotel, at home, and everywhere else I've used it, it worked properly.
My conclusion: touch screens on A500 are very sensitive to electrical problems. I suspect that an airplane's electrical system isn't as "standard" as everywhere else, and whatever the difference was (a grounding issue, or a voltage regulation issue, or whatever) caused the touchscreen to freeze.
My suggestion to the poster and others with "when I plug in the touch screen stops working": go to another location (i.e., a friend's house, work, school, a coffee shop, etc.), plug in and see if the same problem happens. If it does, it might be your charger, so try someone else's A500 charger at a bunch of locations and see if the the same problem occurs.
I would guess that most people with this problem (not the "when I plug it in it gets for a few seconds" problem, but the "touch screen doesn't work when plugged in" problem) will find a solution lies in their power source, not the A500 itself.

I have run into another problem related to touch screens - mine doesn't work on airplanes. I think that there is some sort of pressure differential issue - the screen works fine on the ground, but once I open the tablet when the plane is at altitude, the screen just stops working - it doesn't matter if the tablet is plugged in or not.
Annoying to say the least. Last night I pulled out my wireless mouse to use the tablet, and a stewardess noticed this and told me to put it away as wireless devices aren't allowed on airplanes.......
Any suggestions?
My wife's Nexus 7 suddenly won't turn on... It still had juice when she went to charge it, but the next day found it was totally dead.
I've tried different chargers, tried to get to the bootloader, opened it and unplugged the battery, hooked it up via USB to my computer, etc and nothing will get this thing to power on.
Any ideas?

I've tried different chargers, tried to get to the bootloader, opened it and unplugged the battery, hooked it up via USB to my computer, etc and nothing will get this thing to power on.
Any ideas?

I mean, how long did you leave it on AC power? I know when I drain mine since coming to KitKat, it takes as long as a half an hour to respond again.

Sorry, it spent more than a day on the charger. Still nothing, cannot get it to respond at all.

If you haven't already, try holding the power button for a while until *hopefully* the Google splash appears.
A good way to tell if the device is accepting a current is by using a charger that can verify this somehow, like with an embedded LED. One like this: http://www.verizonwireless.com/accessories/rapid-wall-charger-with-6-ft-cable-for-micro-usb/
I used this for my HTC Rezound when it still worked to make sure it was taking a charge because it would report it was charging in the OS but the charger module itself reported otherwise (the red Verizon ring didn't illuminate unless the charger was positioned a certain way in the device thus this was the only way I could supply it a charge and not hope it wasn't dead in the morning). When my Nexus 7 is drained, it draws enough voltage to get the charger to illuminate so maybe try one of these to really make sure it's still responding.
For the meanwhile, if you do decide to buy one, what was the last thing you/your wife had done? Was there root access?
U need press power for 2 min and need to be pluget into wall

Interesting about the charger -- don't think I have one that does that. Maybe I'll see if my VZW store has one, not sure yet.
She had just used her tablet as normal, and plugged it in like she does every other day or so -- the next morning grabbed it and went to work only to find out that it was dead. IE: not turning on.
- No root access (totally stock)
- I've tried holding the power button for up to 2 mins. - nothing
- Even tried holding the down volume and power for up to 2 mins. together - nothing
- Removed the back and unplugged the battery (plug was really tight) and left it undone for 5 mins and reconnected - nothing
- When plugging in to a USB on the computer, the computer dings like I connected something but - nothing
Perhaps I'll take it apart again and see if I can get a voltage reading on the battery with my multimeter... didn't do that before, but would be good to know if it is charged and not turning on or what.

Remove the back cover, locate the plug to the battery, disconnect plug by sliding from right to left, then replug. Should be fine after that.

Thanks but I already did that. Nothing changed. If I don't get it going soon I'll be forced to buy something else as she is getting impatient.
I have the same issue.
I bought a refurbish one and it was working great for 2 days and yesterday when I tried to open it, it won't turn on anymore and I was able to browse on it 5 min before.
I tried everything but I cannot find any solution...
When I plug into a wall I cannot see the charging icon and when I plug it into my computer it will do the noise that a device is plug but nothing happen... I wonder if its the battery that is crap

I own 3 of these N7 tablets and this has been the number one issue. Sent one for repair when it was under warranty. The supplied Nexus wall charger burn out quick, and aftermarket cables last only 3 months. I've had better results using the Samsung wall charger and cable.
OP, it sounds like your wife's N7 is in APX mode. Connect it to your PC via a USB cable, and open Control Panel's devices and printers panel. If it sees an APX device, and you didn't make NVFlash blobs, your only recourse is a motherboard replacement.

Well, that sounds interesting. Tell me more about the APX device thing. I didn't quite understand.

I just got my new N7 32gb GSM 2012 in the mail today. Won't turn on at all. I'm not going to bother. Going to return it. Quite disappointed, as I didnt realized this issue (apparently with the battery) was so common. Was looking forward to flashing cyanogenmod. Poop. Might just get a samsung tab now, which I think is quite overpriced for its specs.

If you're seriously looking for something other than an N7 then I'd suggest you look at the LG G-Pad.
I bought one for my Dad at Christmas and was amazed by how good the screen is, and the tablet generally, for the price. The LG skin is minimal and can be changed obviously with another launcher, and the battery life is better than my N7.
Folks,
kids got a T580 tablet which, by this morning, all of a sudden didn't wake up anymore. They've been playing games, apparently the device was at 21% battery. Now I can't enable display anymore. Restarting by holding POWER and one of the Volume buttons pressed doesn't work either. Connecting the device to a Linux laptop via USB however shows me a Samsung MTP device connected. Unfortunately rebooting via adb doesn't work, adb claims the device is unauthorized and (with the display off) I also can't change anything about that. Device is not rooted, running latest OTA update firmware. I'm running out of ideas... any suggestions on how to eventually revive the device? Known behaviour?
Thanks in advance,
Kristian
Known? not to me, but I'm new to the A.
Could it just be dead battery? If wall charger doesn't charge it, try usb port linux box, it's a slow charge that way, very slow, but it does work.
Let us know updates, unusual problem...

Thanks for your feedback, greatly appreciated. Unfortunately, battery seems out here. More insights: The device has WiFi on and actually also an IP address assigned. Connecting it to the laptop, I see an MTP and a modem device, and the device also shows up in adb devices. Even hard reboot using POWER +VOL-DOWN apparently seems to work, by then (still connected to the laptop) the MTP and modem device will disappear for a few moments to finally reconnect. Just all the time the device stays dark, I can't even do anything with it using adb because I can't get it authorized without a display connected.
Really strange. I have never so far seen something like that. Any more insights welcome. Especially, is there a way to enable something such as screen mirroring (I have a chromecast around) without physical access to the device? It's pretty difficult to do anything right now without being able to interact with that thing...

Pretty much seems like a screen failure. If it's kids I'd say likely been knocked and probably needs the screen connector/s reseating.
Try to open back cover it's very easy,after that disconnecte all of flix cables (lcd ,battery camera,...etc) and connect them again finally press power button it will work 100% .i did it many times

I will kind of second this. The devices have a tendency to freeze or what we call deep cycle discharge. And many times a simple battery disconnect solves these issues.
We have this issue on the s8 s8+ and pretty much any device it can but more of a pain on a non removable battery
A ittle late and maybe too simple, but my wife's did this and the brightness had somehow gotten turned completely down, to the point of not seeing anything. I fixed it by randomly swiping left to right until I hit the bar.
