Hi to everyone,
I bought my S4 in Germany and I live in France.
My phone, after 10 months started to exhibit strange behaviors:
- Turning off and then turning on by itself
- Turning off and then not turning on, so I had to remove the battery, reinsert it and it then vibrates and turns on for few seconds and then it turns off again
- Sometimes it is able to turn on and it worked
So, I sent it back to the reseller (it was not amazon directly). They told me it presented traces of water and they repaired it on goodwill even if the smartphone should not be repaired because water is not into warranty.
Anyway they sent it back to me, it worked for 1 month, and now I have a phone that doesn't turn on anymore. I told them, they told me it is not their problem and it is not anymore in warranty because I had ONLY one year of warranty (I bought it 'as new' on amazon). Anyway they sent me a new battery and I tried the battery on another S4, it is working, so the battery is not the problem.
I went to an authorized shop to get it repaired but they told me that they wanted crazily expensive money. So, I am a robotics engineer, I decided to repair it by myself and that is why I am here.
I want to ask you what could be the problem. I read until now 2 possible reasons:
1) The power button is faulty. In this case is there any way to connect the contacts the button connects with an hard connection?
2) The USB board is not charging the battery. I tested with a multimeter and the + - voltage on the battery was always around 2.62/2.64 V. I don't know if this is normal but I checked that the part is not expensive.
Thanks a lot for your help.
The USB board isn't expensive but I don't believe the USB board is the problem here. Lithium batteries come partially charged when new, so if the S4 didn't turn on after putting the new battery in it, then the only remaining issue is the power button. Buying a replacement power button should be just as inexpensive as that USB board. Plus, being a robotics engineer you should have basic knowledge of soldering, meaning you could replace the button yourself.
It does sound like a power button issue.
A set of 4 buttons is about 5 dollars on the internet.
I'd recommend opening the phone up and checking the power button with a voltmeter.
If it is the power button, then simply replace it. It doesn't seem hard. Here's a guy with a power button issue. You can see where to check and how to replace it.
Thanks. I will try with the voltmeter. Thanks a lot.
So, I unmounted everything and tested the power button. I am quite sure it is faulty. ( I will be 100 % tomorrow because I could test only with a really bad multimeter) .
Anyway I have a question in the meanwhile. Is it normal that the red charging led doesn't show up when I connect to the power supply ? I think it could be possible that the faulty button induces a problem like that but I would like your opinion about it.
Thanks.
I don't think the power button would affect the LED. A friend had a problem with the power button, but I don't think it cause any problems with the LED. I haven't noticed. But my friend would've noticed if there was any and would've told me, which wasn't the case.
I tested with the GOOD multimeter and it happens what it is showed in the video you posted me in a previous post.
The button has 3 pins:
pin1
pin2
pin3
If I check for continuity between pin2 and pin3 there is, as it should be in a working button.
If I check for continuity between pin1 and pin2 there is, as it should NOT be in a working button.
Having continuity on both checks means the buttons is continuously pressed. So I guess you will have to change it.
Yeah, I know. I already ordered it. It will arrive on Friday.
What I was wondering is if this could give also the problem of the LED. What do you think?
I removed the button. I placed the battery in the phone. Put the charging cable. But nothing is happening. This looks strange to me because without button it should at least appear the battery icon. What could it be ?
Thanks
Maybe your phone bootloader is so old that it came to a situation where samsung's signing for this bootloader version has expired then ABOOT doesn't allow you to boot.
Just a suggestion and nothing else.
But this could be else used by samsung to force you update your phone.

Not if the circuit isn't complete. The button completes the circuit, which would explain the lack of any indicators.

Why should be that ? My phone was working perfectly before and at some point the bootloader is not good anymore. Anyway thanks for the hint

Ok so I was so happy that I finally got XDA live .2 running on my 1.5 month old Hermes. This site has helped me to no end. Being completely new to the Windows mobile platform, I've made it a point to check the forums here every day and read up on issues/tricks & tips. My utmost respect to the folks here at XDA-Developers. In fact I just contributed some money I was so thrilled. I never had to post a question before.
Short lived :-(
Due to my own stupidity. I dropped my Hermes on the carpeted floor in my office. Now it wasn't a huge hit to the unit. It fell 2.5 feet and it was carpet.
I picked it up and hit the power key (It was sleeping before I dropped it) but no joy. I yanked the battery, waited a minute, replaced it. No Joy.. I've tried lots of stuff
1) With battery in place, soft reset
2) Without battery in place and attached to power.
3) removed battery, waited an hour, replaced battery. No power on. Re-attached power.. No power on.
So long story short, I can't power it up. I get a red light when attached to power with or without battery in place.
I am screwed? I'll cry! I have removed the sim-lock and I am Super CID on the phone. It's over a month old from Cingluar. Do I have any hope of getting it fixed/replaced/someone here suggesting a fix?
Any help appreciated. I saw a post on the red light when charging but nothing so far has helped.
I know they are many genius' here. I'll donate more to this awesome site regardless of getting this fixed. I just hope I don't have to fork out another $500 for a new unit.
What we don't know in your case is whether dropping the device has just triggered the infuriating Red LED issue that will come good or whether more serious damage has occurred.
You say you read a post re this and I assume it was this one?
http://forum.xda-developers.com/showpost.php?p=1077622&postcount=6
The one thing I did not see that you tried is having charger plugged in with battery out and whilst remaining connected inserting the battery. Wait several seconds, hopefully LED changes to amber. However, though frustrating it may be worth repeating this kind of thing repeatedly until you are bored to tears! I say this because some folks find that it just seems to start eventually but they've tried so many things they cannot pin down what exactly the solution was.
If it's more serious - which I rather doubt (only 2.5ft to a carpeted floor) then you could try a disassembly and reconstruction. (I'm assuming you do not have warranty) I suggest this as the first time I got this, this is what I did and on re-assembly - hey presto it worked. Did not actually do anything but perhaps it helped with a loose connection or helped discharge the circuits and reset charging function??

Hi,
had the same issue! No function, only red light - with/without/new power plug, accu - only red light.
My device only layed on my table at home - overnight crash effect...
I had to bring in the device to service...
Now i have a new one with higher s/n and all is good again...
best

Would having a second, fully charged battery help?
Sincerely,
Steve
It's going back to cingular.
Thanks for all the advice/help. Nothing seemed to work at all. Different battery, attching to power and inserting the abttery afterwards. However, I now can boot trhe unit, but I have to squeeze the sides of the unit (Or jam a piece os plastice bettwen the slide out keyboard) and the unit boots. Not very practical.
I contacted Cingular and a replacement is on the way. I put back on the original ROM that it shipped with and wiped everything else. I am Super CID, does this void my warranty? Will they even care? The issues is definietly HW so I hope they just can't power it up when they recieve it back. I'll play dumb anyway if they ask!
Now it's just trying to survive the next few days with either my SE P900 or My S710 (Sniff... sniff.. I want my Hermes back already)
Thanks again to all who posted advice.
Hey sorry if this is not where it should be but my power button started to really become quite "laggish". Takes like 5 presses to wake my phone and turn off the screen. I flashed Miui Rom on my phone with a random Buuf theme. Never had the issue before but when i tried to reflash the rom I noticed in recovery i had a difficult time to select options because of the power button. Is this common for anyone else? Is there maybe a fix out there that people have done?
It's common and eventually it will stop working. My first N1 lasted six months before the power button stopped responding.
Have fun sending it in to HTC for repair. When I sent mine in they claimed the screen was broken and held my phone hostage for $116.
I've had my replacement for another 5 months and the power button is starting to get flaky again...

Ugh this sucks I really didn't want to have to buy a new phone/spend money on repairs for like another 2-3 months until they came out with somthing better than the mt4g and or NS
Are you under warranty? I just replaced a Nexus One under warranty for the same reason and it went very smoothly. If not I here you can send it for repair but I am unsure of the cost. I have heard reports of people getting a digitizer repaired for around $120 so I would imagine a power button replacement would be that or lower.
Trackball wake is your friend. Also if it completely breaks you can wake the screen by plugging the phone into a USB port. You can boot the phone by plugging the phone into a USB port and removing and reinserting the battery and the USB cable in different orders. I have done it many times but I can't seem to figure out the exact order.
Good luck!

Thanks for the Ideas =] btw anyone have any other idea in terms of what would be a good replacement phone to purchase?!?
This is why I've used track ball wake since owning this phone. It shouldn't be this way, but why risk it with all the failures we've seen. Crosses fingers.
My Power button seems to be doing the same thing but I was blaming some of the custom roms I've been using. It only does it some of the time. Just seems to take a few seconds to wake up.
I just tested and continuously hit the power button and had a 1-1 success of turning the screen on and off. Is this the same for you or is it always flaky?
Warrenty is up my power button is barely responsive. Using touchball for now

yea i just started using MIUI with Buuf theme and the **** went haywire i hoped i would have been able to hold out until dual cores but idk if it will last that long
its a common fault. I just recieved my handset back yesterday from HTC, all fixed at no charge.
can u use the trackball wake method from a cold boot? i.e when swapping sim card or removing the battery and you need the phone to turn back on. I found trackball wake only work to wake the phone up from standby mode in my Widget Locker app.

I don't think there is an app that will let you boot the phone with the trackball, but as I stated earlier in the thread you can boot the phone without using the power button (if it breaks completely) by plugging the USB cable into your phone and then removing and reinserting the battery and the USB cable in different orders. I am not sure of the exact order but I have done it many times.
I'm glad it isn't just me :/
I have to sell the phone before it completely stops working then .. lame.
Buying on craigslist has its cons.

How long did it take? I've been in contact with HTC support and I would have to send it to the UK (I'm in Sweden).
I know that this questing was made thousand times...but my problem is a little bit different...
My dad has the N1 and he destroy the power button with his detestable streghness, and stubbornness to shoutdown the display everytime he did something...I hate his way to use phone and than blame me! -.-
So know I have to solve this problem...
First of all I have to power up the phone...I've follow the trick with the battery it started one time, then I can't start it anymore...
Then I'd like to know if I can take it to customer care also if there is a custom rom but I didn't unlock the bootrom just root it with "superoneclick root"
If my phone is not in warranty how much costs to replace the power button?
Can I repair it on my own? maybe the little power button inside is just moved and the button outside can't push it...
I've experience with a P990 that I've disassemble to change the cover...
Thanks a lot for your help...
Your problem is ABSOLUTELY THE SAME as any other "My power button died!" problem.
Please bother reading the zillion threads on the subject, looking at the price of flex cable on eBay, looking at the Nexus One disassembling guide on Youtube, and deciding what to do.
I don't see the fuzz about not getting the phone to boot up. Are you 100 % sure you're doing exactly as described?
First, plug in the USB cable or the charger, with the battery out. Insert the battery as soon as you see the led light lighting up. Now remove the battery and keep it out until you see the led light fading away. Now insert the battery again all while the charger or USB cable is still attached and it should boot up.
You might have to repeat it around four times, however.
When my power button first broke, I thought I was screwed and I tried the battery trick and it wouldn't work. Then I rechecked the how-to guide again, thoroughly this time and I managed to get it to boot up. It seems to boot up at a ranom amount of times. Sometimes, one single battery pull and insert is enough, while other times it takes two to four tries.
Now, though, I don't see the need of paying a lot of money to replace it as I have learned to live without it completely. With the use of either volume rocker wake or trackball wake. The latter I use all the time if it works well with the ROM I use. When I used Sense, I had to go with volume rocker, but it did the job. If I need a four-way reboot, I simply open "4ext recovery control" (which for the record is worth the money for the full app) and then enter "power menu" that way.
The power button on the Nexus One is really not necessary as there are plenty of workarounds.
This is like the millionth topic describing the same thing and I'm sure a simple search could have helped you more.
I've try your method and nothing I can't start my phone anymore, the light is always green and the last time I success to power on N1 was when the light was orange
I don't know what to do also because it's installed cyanogenmod and I think that is out of warranty....
If I just can power on the phone I can at least save the contact list
EDIT:
if I plug the phone to the charger with no battery, I have a led green and red that go on and off
This is normal and expected.
Green light means charged battery.
Alternating light means no battery.
Everything is just as it should be.
I guess you won't bother reading/trying, so I'm not sure why should anyone bother answering.
Jack_R1 I've read every topic on the board about the power button...so I don't want to make a bad discussion here with you...
I've read that I have to call htc or open it by myself...but I'd like to know:
1. the phone won't power on with green light... so the trick doesn't work?
2. can htc recognize that I have cyanogen if the phone doesn't power on?
3. can I repair on myself without buy a new power button that I can't find on ebay? or better I have to replace the entire flex mobo and the cpu?

1. Works for me.
2. Sure they can. They can also refuse repairing it or even charge you for it.
3. You only need to switch the flex cable. No need to replace both the logicboard and cpu.
I'm not sure why you can't get it to work. I think you're not exactly doing what you should with the battery trick. I'll try to explain as easy as I can:
1. Insert the USB cable or a charger and remove the battery.
2. The led will start to blink, but that is normal.
3. Insert the battery. Remove it again and wait until the led starts to blink
4. Now insert the battery again.
You shouldn't have to repeat this more than four times.
You can repair it yourself, if you search the forum, find the photo of the flex cable that someone posted with the exact point you'll need to solder to, disassemble your phone, and solder a very thin wire between this point and the power button. Personally, it took me 1 hour to do it for a friend, using lab microscope, super-thin wires and very thin soldering iron. If you have the equipment and the skills - go for it.
But if you had the equipment and the skills, you'd most likely be able to write "nexus one flex cable" on eBay and find this:

HTC quote for repairing out-of-warranty N1 with power button failure will most likely be equal to the price of used N1 these days.
Since yesterday my SGS is having a very strange issue: It seems that the power button is stuck on pressed state. When the phone was on I had the power menu appear and the phone shut down. Then it started again, only to turn off shortly after the second screen during boot, then looping in that state.
When I remove battery and put it back it automatically starts and then bootloops.
I can't get into recovery as it turns off before recovery can start. I can get into download mode but only for 3-4 seconds till the phone turns off again.
I removed the backplate and can't see any visible damage to the power button. Between the power buttons pins on the board there's a voltage of 7mv with battery removed, in case that means something to anyone.
So 2 questions arise:
- Any ideas on how to fix this? (apart from ripping of the power button which I'm not even sure would help)
- Any ideas how to get into a mode where I can backup my data or at least flash a stock rom? (Currently on CM9 with devil kernel and the devil logo shows for a second in the bootloop, not sure how the techs would like that if I was to sent it in for repair)

Has there been any water damage to the phone/button? Sometimes this can cause the button to short. Or it might just be stuck, does the button physically click in as normal?
It could also be worse and have an actual hardware issue with the motherboard/power button interface
there hasn't been any water damage. actually, it's been used in the rain but that shouldn't really hurt a phone... just in case i let it try for quite a while but the problem didn't go away.
the button clicks as it used to do, no sound of water or damage there.
problem hardly could have been worse as the phone is completly unusable in this state as i can't even turn it on.
Hi,
A friend has just handed me an abandoned SGS with precisely the same problem.
The power button itself feels fine, ie it doesn't feel stuck, and you can feel it clicking as normal. I too removed the backplate and can't see any visible damage to the power button.
I note however that the water damage indicator 'sticker' mentioned here: "samsunggalaxysforums.com/showthread.php/4674-Galaxy-S-I9000-Service-Manual-How-To-disassemble-your-Galaxy-S"
is completely white, indicating possible water damage at some point.
Any ideas for a fix, or do you think it would be economical to seek a fix from a hardware repairer?
I can replicate the problem as described by XlAfbk above, by simply holding down the power button on my working i9000.
i did sent to phone to the only service location samsung lists for germany. they claimed it was water damage and refused to repair under warranty. repair would have cost ~280 euro.
i'm waiting for the unrepaired device now and will try to fix it myself, in the meantime i got a gnexus
Ok thanks. Please keep me posted if you do find a way to repair it yourself.
Until then, I guess mine's spare parts!
no more warranty for you? if you're in germany PM me for a repair shop.
ebay has power button replacements for ~4€ that you could try soldering on, replacing the original one, if that's what's broken for you. I checked mine with a multimeter and as there's still resistance it's not the power button for me.
uhm, I actually did fix it... while it's not completly back to normal i can at least turn on and off the phone, just turning display on and off with power button still doesn't work
some dust had gathered on the board, apparently shorting a circuit. just grab a brush and some canned air and clean the board.
i cleaned the main board at the very top and the bottom one near the middle (PM me for a photo of the location)
Nice that it almost works now. Just thinking what an asshole Sammy is, they want more money for a maybe ~20€ repair than the device costs bought new.
the repair wouldn't have been 20€, they'd have replaced the whole mainboard for me, not just the power button. I have no idea whether just replacing the power button would help, just brought that up as that's the one item that could possibly be it and you can get for cheap.
my power button got worse again since my previous post btw. so something else must be wrong as well.
After my phone was on a rainy trip, I am suffering from the same issues as well. I checked the resistance of the power-switch, and the open-circuit resistance measured to 30 Ohms, while the closed resistance measured to 0. Of course, the open-circuit resistance will not measure the switch isolated, but still, I'd expect something in the range of at least some Kilos. Hopefully, the switch will function normally in some time (if the switch is the only problem).
if it doesn't fix itself remove the mainboard from the housing, check it using a strong magnifying glass for any traces of water (tiny white residue spots) and carefully clean them using with a small brush (and nothing but that!).
of course doing that will void all warranty!
I completely disassembled it in order to clean it properly, but it did not yield immediate results. However, however a few days of rest and it came back to life, and has been stable since. So it looks like the rest is the best advice for other unfortunates.

It seems there are already several threads about this seemingly common issue with this tablet, but I've tried the normal checks and still can't get any life out of my dad's nexus 7 whatsoever.
I've found several threads stating it's just a loose battery, but in this case it isn't. I've checked absolutely every single connection I can get to without removing the void if removed bits, and can't find anything suspect. However it still won't turn on, won't charge, etc. It's not a faulty charger or cable either, we've all got android in my immediate family and we can't get any life out of it with any lead or charger. It was simply working one day, it was turned off the way it always is once my dad had finished using it, and now it simply won't come back on again.
I also saw some people say to get it into bootloader mode by holding volume down and power straight after plugging it in, but that too does nothing whatsoever?
Does anyone know of anything else I can try, short of sending it back to Asus?
How long have you had it?
This sounds like something that should be addressed as a warranty situation, as anything else may be kludgy at best, and may fail again just after your warranty runs out.
I wouldn't really waste any more time.
JMnsHO.... :beer:
My dad has had it about half a year, maybe a little more. But he bought it from Comet, who no longer exist since they went under just after Christmas, so he can't return it to them now. Unless it'd just go straight to Asus instead.
I had exactly the same issue.......I fixed it by disconnecting the battery and reconnecting which by the sound of your post you have already tried.......you should be able to go straight to Asus for repair.......good luck....
Sent from my Evo 3D GSM using xda app-developers app
After probably 30 days it would need to go back to ASUS anyway.
As I'd said, I wouldn't waste more time fussing with it.
They'll take care of it and still preserve the balance of the warranty.
If you messed with it too much, you may find yourself with none at all, and on the hook for the cost of the repair.
Make the call.. :thumbup:
Well I've not done anything that shows I've been in there like I say, so any manufacturer warranty should still be intact. Same goes for the software too, not rooted, on the standard rom and kernel, etc.
I was just hoping I could fix it for my dad without having to send it off.
Not yet, but anything else would be more 'intrusive'.
How long have you been working on it?
Not long, only 10 minutes here or there to see if I could find something loose. I might check the voltage of it's battery to see if it's flat, and also check to see if any power is getting to the battery while charging. That'll help prove if the battery or it's control board is dead or not.
Just checked the battery over. It's a 3.7v battery according to the label, and my multimeter shows 3.7v, so the battery is fine with no loose connections. At the connector for the power button ribbon cable, I get the 1.8v that should trigger the tablet to power up when the power button is pressed, and the power button is good too, only showing continuity when pressed. Again, no loose connections. But the bloody thing still won't turn on.
Any more ideas?

Yes, your thread is about a faulty or loose battery. As I've said, it's not a loose connection and I've now tested the battery too. Unless you can think of something that I've missed?

That sticky has all of the well-researched methods of addressing the collection of related issues (won't turn on/won't turn off/battery status). It is not only about a faulty or loose battery - there's much more.
Give it a read and let me know if there's a fix in there for you.

If your able to get to bootloader maybe try to power off then let it charge for awhile then boot, or hold the power button for a good min
It won't turn on at all, so it can't get into the bootloader. Tried already.

I know you tried almost everything in the box, but when you plug it in the wall and press and hold the power button do you see the screen light up but still black?
If yes ( hopefully ) then continue holding power button then press VOL down til arrow pointing with START appears. Cycle through with VOL down til you see power off and select.
After it shuts down unplug from wall and replug and let it sit for a long awhile
If this didn't help at all sorry......good luck....warranty?

Nothing happens whatsoever mate, even while plugged into the charger. Tried the original charger, my s4 charger, my old HTC chargers, from the pc via USB, etc. None of them make any difference.
Got a feeling it might be the motherboard, as it has power. Can't be the display since I've tried getting a logcat from it after holding the power button for a while to make sure it would have turned on. ADB just kept saying "waiting for device" as if it wasn't plugged in, confirming it isn't even turning on.
Can anyone think of anything I've missed?

Can the pogo pins be used to charge? bit of a long shot and you`d need to buy/borrow a dock of some sort. Definitely sounds like a hardware failure issue.

Pogo pins?
It already seems to be charged though.
