Battery won't charge, power button broken, me going crazy

Ok, im going to start not from the beginning beginning, but from where problems started.
Friday night, went out, I was writing an sms when somebody pushed me and i dropped my wiz, i picked it up, to find that the battery was gone, nowhere to be found, i did find the cover tho. i tried to look for the batt, but i was in the middle of the club so it wasn't that easy.. I knew that a friend of mine had a spare one so i didn't worry that much.
Sunday I got the replacement, tried it, no luck, it ran out i thought, but when i tried to charge it, nothing happened. Buying a new one is not that easy when you are in Argentina, and they are expensive, so i decided to jump sart it. good news: it worked, i could turn on the phone, so the battery is fine. bad news: it still doesn't want to charge!
I previously had problems with the usb, and i had to have it soldered again, pretty strong, but I thought that might be the problem again, so i disassembled my wiz. new problem: the power button broke, the tiny, tiny black piece fell off, AND I LOST IT! DOH!
Anyways, the usb is still soldered pretty strong, i don't think its gonna go loose again, so thats not the freaking problem!
So now, instead of the initial no-charge problem, i have a disassembled wizard, that won't charge the goddamn battery, AND a broken power button (tried to glue it, but fell off again and thats when i lost the piece).
Regarding the button, i've studied my options, what would you recommend and how would you do it?
option 1: turn on the phone with the soft reset hole, and remap the screen on/off function to another button.
option 2: replace the power button internal piece with the one from the voice command button (i never use it). i've taken a look and they seem to be the same, but i don't know if taking it off and soldering it back would work..
anyways, that leaves me again with my initial problem, and i do have an hypothesis. I THINK (because I THINK i remember this happening to me before), that the battery won't start charging until windows has started, and the jump star power the battery has is not enough to get it started (tried to tape it and leave it for a while to see if it charged a bit more, but didn't work, the phone turns on but goes out when loading, and since i've my wiz pretty loaded it takes its time to load).
So to try this out i would need a way to charge the battery manually, and i don't have access to another wiz to have it charged (my friend had a spare batt because his wiz is broken).
So, if you have a solution to this, ANY different solution, or even an IDEA, please give me a hint!
For what i've read, this are common problems, so there must be something out there.

Man, that's a bad thing
I'll try to help you as much as I can.
You are right about Wiz only start charging when it's on. After my N78 was stolen and I went back to the Wizard, the battery was without any charge for months... I plugged it and no red LED... Turned it on and, bingo, red LED and charging!
The voice command and the on/off buttons are the same, so (in theory) it would work 100% IF you were able to change their places (at least for me, it is impossible to do manually, never found any good equip here =\ )
With a lot of patience (and a small soldering iron) I would try to take the voice comm button off and place it where the on/off was.
For the battery, maybe someone here can point if there is a "battery charger" standalone device, or such a thing...
Good luck man

hey thanks for the quick reply!
i'm not thinking of doing it myself, i'm not not that precise nor is my solder, but i know a guy, same dude that fixed my usb. I like that idea more than the other, but i guess that remapping the screen on/off and using the soft reset button would be much safer.. i haven't made up my mind about that yet.
Weir thing about MY wiz, at least thats what i think happened to me last time my battery was completely discharged, is that not only the device must be ON for it to charge, but it needs to have WINDOWS already loaded, i know for most devices it's not like that, but i think thats how mine works, or at least thats the only explanation i could find!
btw, i love your case modding concept, and since i might have my wiz sitting for a while, i might go ahead and try something too! nothing as extreme as yours of course.. i'd love to see more updates on your project along with some guide to see what ideas i can take

slight detail while thinking my options.. if i was to remap the screen on/off function to another button, would i need to have the device in sync? or connected via cable? because when i had the usb soldered, don't know how nor why (all the pins seem to be ok) but the device won't be recognized by any computer, usb only works for charging (or used to work, at least, still haven't figured why it won't charge now).
If its only an app that i can load to the phone, once i have it working (that if i ever will), i can load the app thru minisd, BT or IrDa so that would't be a problem.. i haven's investigated that issue yet.

Hey jinxie, how's your Wizard?
If you're still stuck with the battery (I hope not), check this out...
I think this will solve your battery problem:
http://forum.xda-developers.com/showpost.php?p=4963547&postcount=5
That's probably to work, just be carefull with the battery's temperature. If it starts to heat, stop the process and wait it to get normal, then start again.
Good luck!

i tried keeping the wires attached to the contacts for a while, didn't think it'd work better doing it just for a little and then repeating the process, i'll try that!
yeap, i'm still stuck and i think i will be for a while, i have to solve the battery issue first (would be useless to do anything else if i'm not certain i will get it to work), then i have to decide what i am going to do with the power button, and then i might paint it, i'm thinking matte black, or maybe take some ideas from your project if you have made any progress at the time!
thanks for the tip, i'll try it today and i let you know how it went

development: phone DOES NOT turn on with the soft reset button as i thought, i was sure it did, but after jumping the bat once again, tried the wiring method (not repeating the jump start but wiring it directly to de device pins), and tried to turn it on with soft reset and dind't work, while it does turn on with the power button, wich is broken, so in order to turn it on i cannot have the phone assambled, wich means that in order to try to make it work, i will need to hold the battery attached with my hands, and it is a pain in the.. you know where.
update: i wired the charger i was using to jump start the battery to the pins in the wizard, then held the battery in place with my hand, with a small screwdriver i pushed the broken power button. wizard turned on, IT FINALLY LOADED WINDOWS, but don't rush, i then (with my MOUTH) connected the USB wall charger to the port in the phone, and removed the wiring, i was expecting the goddamn light to turn on and the screen to tell me that my phone was finally charging. I WAS WRONG. then i had to let go because my hand was killing me and it went off
and the damn thing refuses to charge! what could it be????????
2nd update: I AM MACGYVER !
i figured the wiring had given the bat enough power to load windows on its own, so tried once more holding everything together with my hand but without wiring the pins this time, and at last the amber light turned on!!! im so proud of myself lol
SO NOW: device works ok, charges ok, battery has enaugh power to load windows, WHAT CAN I DO ABOUT THE BROKEN POWER BUTTON? i know you can't remap the power function since its hardware, but the screen on/off function might be remapped. soft reset button DOES not turn on the phone, is there any other way of turning it on? or my only option is to take off the voice command button and soldering it where the power button should be?

well, found the little button part that was missing, glued it (yes, GLUED it), and it kinda worked, i had painted the casing already, so i assembled everything back again. i used a folded piece of paper to hold the button still so it won't fall again and i think it was too big cause now its kind of hard to press but i can live with that, what i cannot live with is NO SIGNAL.. i mean, CMON!! are you kiddin me? now that the button works, battery works, phone assembled, and now this?? when i dissassembled the phone i forgot to take out the sim card, so the metal parts that hold it opened a bit, but i pressed them back, the sim in no way loose, so i guess i might have screwed the attenna :S
i've just checked, i can see the sim contacts so... [CENSORED] !!!
also now the screen looks weird.. like if it had less colours, like when you format your pc and haven's installed the graphic drivers yet, 3d effects look funny..

Hey man, have you painted ALL the Wizard parts, on both sides?
'Cause there is one that has a piece of copper board inside. It makes contact with the antenna. Without that contact, you'll never have signal
The piece I'm talking about is the one that has the camera protection, saying "1.3 MP camera". Look at its back and see if there's no paint on a green and golden plate. Remove the paint if it got there (the golden part is the important one, since it makes contact with the antenna).
Good luck man!

hahah lol, no of course i didn't paint both sides! but anyways im gonna take it apart again, clean it, and try again..
done. it had some paintng yes, but they were very tiny spray drops, so i don't think that is, anyway i cleaned it. On the other hand, i found that the antenna is loose on the left side :S what can i do about it?

Nexus One power button fix

I just bought a replacement power button/ flex cable for Nexus of ebay. Took me around 30 minutes to replace it but its fully working right now. Its around 30 £ .
Item name it "Flex Cable Repair Parts for HTC Google Nexus one G5 1"
Just thought i let you know .

Any pictures?

Is it a tricky fix? I replaced my digitizer just fine so hopefully this wouldn't be a major repair job in comparison. Would love to have my power button working again!

I don't understand why you fixed it yourself, I sent mine back to HTC.

How much did it cost for the repair out of interest? Did it take them long to get it back to you?

Just curious if to you it looked like a bad button connection or a bad cable? I know sometimes the buttons get crud in them so they dont make a proper connection...

Great info. Too bad we don't have step by step pics. How did you take the phone apart and how deep did you have to go?

Does anyone know why the power button breaks? I have my N1 a year now and (luckily) i never had a HW issue. anyways i was just wondering why it breaks .
Step by step pics would have been nice.

The power button itself has a small cylindrical piece of plastic which pushes against and presses a small connection that sorta clicks (Which gives you the tactile feedback you feel). I think the problem occurs when either 1) The piece of plastic either bends/breaks/gets damaged in some way that makes that contact much harder to produce 2) The connection is connected to the phone via a cable/flex, however due to the Nexus one design it is bent around in order to be below the power button, while this is fine for the majority some devices, including mine, have seen the flex become damaged for whatever reason and either function intermittently or not at all.
It's also interesting to note that there is nothing holding the flex or the connection in place except for the design itself i.e. the battery bay plastic holds it all in place. My power button was never that responsive (But got progressively worse) so this may explain why.

Its always flex cable breaks and there is no way you can replace just the flex cable.You can find plenty of disassembly instruction over the net and yes you need to disassembly it to the pieces( still less to do than to replace digitizer.)I had a seal broken so i couldn't send it to HTC.

I did some googling and found a few images of that component, I remember taking it out and it was pretty simple so it should be just fine! Thanks for the info!

Is it the Power button part that you changed ?
Hi,
I have found a photo of the power button part, can you tell us if you changed the full part shown on the photo ?
androidguys.com/2010/09/08/manage-nexus-broken-power-button
And i think you paid it way too much expensive ?
Thanks.

I just replaced my flex cable as well as the loud speaker as well.
iFixit has a few pictures and there is a video on youtube, of the taking apart process. Unfortunately I can't post links
There are two little rubber parts that will likely fall out during the mainboard removal. One goes underneath the connector beside the sim card and one is a part of the microphon.
I wish I could have taken pictures of where those parts go, but alas, my only camera right now is my nexus, so....
BTW, I bought my parts at Mobile Brando. Quite well priced as compared to many other stores of the kind.

was it the whole board that you've replaced? or just the flex cable for the power button. can you further elaborate the steps that you've done?

So this is the item that you purchased? http://mobile.brando.com/google-nexus-one-mother-board-flex-cable-ribbon_p6193c1023d88.html
Can you confirm that the 3.5mm jack is on that board? Additionally, is that motherboard and flex cable for the AMOLED version or the SLCD version?
Do you need to remove the screen and risk getting dust inside there to swap this part?

Hi,
That's exactly the item, at that very same store. I also bought a loudspeaker as well as both back covers there. The audiojack is on board and I believe the flex cable has nothing to do with the screen type. The screen does not have to be removed.
I used those pics: http://www.ifixit.com/Teardown/Nexus-One-Teardown/1654/1
and this video: http://www.youtube.com/watch?v=cznogushN34&feature=player_embedded to figure out how to do it.
Basically, it's quite straight forward, given that you aren't a clumsy oaf ;-)
Remember the two rubber parts that might fall out when you pull off the mainboard assembly. (one at the bottom, for the microphon (http://guide-images.ifixit.net/igi/fpRmPyN6h12mtNvt.huge ,a bit to the left of the plastic tool) and one at the connector beside the sim card (http://guide-images.ifixit.net/igi/EOfeocuwhCRASB6M.huge , on the left part, somewhat down from the serial number sticker).

I have this probleme, but this part costs too much :S....

10. pin ON OFF way in board socket... u make jumper to on off buton

I have replace Power button for my N1. But you can reset your N1 by do'n need it. Except when you want flash rom!

strange power button behaviour

Alright guys,
I already posted into the Android Q&A Thread because I thought it's Android related but it's not.
So I'm posting here again.
My power button drives me crazy .. I'll explain it in detail.
I can't turn my phone on using the power button, only by putting the battery out and in while connected to the charger.
BUT the power button works flawlessly after the phone started.
I tried 2 different android roms (gingerbread & jelly bean) and the stock wm 6.5 rom.
same result so far.
I can turn the phone on recently after powering it off using the power button.
just if I wait a few minutes and let it "cool down" it's not powering on anymore.
could this be related to any elecricity that's gone in the meantime?
checked the pins and they aren't bend. battery charges fine too.
I'm out of ideas so I hope someone is being able to help me.

Has Same Problems
It might be mainboard so need jtag ti rebuild checksume
Sent from my HTC Desire S using xda app-developers app

uhh I hope not.
don't know anyone who'd be able to do jtag for me

ok .. this is .. how should I explain it .. STRANGE!!!!
just tried to power on my phone using the power button as usual .. no effect.
I put the phone on my radiator for 3-4 minutes just to see if it makes any differences with a certain temperature.
and it's powering on again.
so the problem is the HD2 not having this exact temperature after being shut down for several minutes
WTF??

Hardware issue.
Maybe button board, mainboard. When it's at certain temp circuit/component working, when at lower temp circuit open/component failure.
Worth checking battery pins again for straight & cleanness & also perhaps another battery if possible just to rule it out fully ...

thanks for the reply.
I tried 3 different batteries so I doubt that's the case.
checked the pins again and they aren't bend or corrosion on it.
too bad I can't check the mainboard again or even replace it.
had to replace the touchscreen / digitizer and when I try to open the HD2 again now they both would separate from each other.

got another question.
is it possible to open up the HD2 without the problem of the digitizer and touchscreen separating from each other?
I'm not able to change the motherboard if so.

If assembled correctly centre chassis, LCD & Digi come out as one unit bonded in layers.
I assume your bonding of digi, lcd is not the best hence easy parting on first stage of lifting chassis from casing. Problem is all but the very best industrial strength tape is all but useless, I use pu40 adhesive spotted in high lift areas & near edges so easily freed for future strip & best tape I can find for the rest
If layers separate you would need to take great care not to put load onto the flex cables.
I would recommend reading the repair guides & videos again as bad technique will not help & simple point of pushing lightly on build sticker can make first removal step much easier.
Good motherboards are hard to find at worthwhile cost ...

the digitizer and touchscreen have already been replaced by me. it's been an already soldered version from Taiwan. Seems the glue used to fit digitizer and touchscreen together is as you already stated not the best.
I'll just bear with it and sell the HD2 for some low money. this phone drove me up the wall too often.

Is it possible to use a key map app to remap this key? and you will see what kind of problems it have(hardware of software).

Resurrect a dead M8, mate?

Hello,
I acquired an HTC one M9 to replace my dead M8 that I caused (funny story at the end). The headphone jack was wonky, and since I had disassembled and reassembled an iPhone 4S in the past I thought I could try my hand at this. The hardest part was getting the M8 out of its metal shell, and I think that's when I may have damaged something. I was able tot get it back together, but it will not power on.
I can plug it in to a charger and I see the screen come on showing that it charges and that there is a healthy power level to begin with. I can no longer find the plastic power button though, so I have to use a screwdriver tip or a spudger to press the sensor to turn it on. I've held it down for 30 seconds, 1 min, held it and the volume down button for the same amount of time, and tried the same with the volume up button, but no luck. I keep the shell off of it when I attempt to revive it, if that makes a difference (slightly easier to reach the power on button at the top). I can possibly put it back in the metal case and try to hold down all three buttons, but it's a ***** to get back out of the case.
I remember reading a few threads here or elsewhere regarding the ability to jump start a dead phone or android device, perhaps it was a Nexus 7. Is there anything like that in the development package or a standalone program where I can connect it via USB and jump start it that way? Or is it pretty much toast at this point? I see replacement power buttons and power button boards on eBay for under $20, but with my (lack of) skills I believe I'll just damage it more. What are your thought and what are my options?
(Funny story). I purchased my HTC One M8 from an eBay seller, yet when I got it, the power button was not on top but on the right. I'm thinking, "okay, didnt know I'll have to start looking for alternate M8 cases...". When I called Sprint to activate it and provided the information, they said it was actually an M9! So the reviews aren't as favorable towards the M9 as they are the M8, but I love it nonetheless. And of course if anything needs replaced I'm just going to take it to a brick-and-mortar shop to have them do it, save my spudgers for working on laptops.
Thank you for the help and advice!

Unbelievable i pretty much have the same problem since yesterday.
Ok i try to write this as short as possible.
My Headphone Jack was also broken so i bought a new USB/HJ/MIC part.
After putting it in i wasnt able to load my phone anymore with the new piece so i tried back the original one with the dead HJ and it worked again. So i let it inside, contacted the seller to send me a new one. Which is not here yet, but he doesnt want the first one he sent me back, which is quite fortunate.
However yesterday i dropped my phone on high grass - it was completely dead so i couldnt call it using another phone thus i wasnt able to find it for like 1hour, it was dark, and very cold(-2°C) and also wet and i think this is how i broke my M8. But im not sure yet. I used a flashlight and apparently found it after some help of a friendly lady.
When i was back home it didnt start. Not even when charging. Then i thought myself i will try the new part again with the "broken" USB Jack and pretty funny it somehow works. BUT: Charging it turns on the screen instantly, gets me into recovery (always did that, never startet directly into CM13 which is use) but after like 15seconds it just turns off and starts again, showing me the dead battery icon at first, then the recovery. Im not able to turn it on using the power button (didnt loose mine ) it just turns it off because it starts by itself when chagrer is plugged in. I dont know what to do now: i dont have enough time inside my recovery (CWM) to reset it or something and im not really sure if it is a software or hardware problem but i speculated its the battery which is broken now. (?) However when i put the charger in to make it start, then pull it is able to hold itself for the same duration as if i was charging, but only sometimes. This really confuses me.
I dont think i broke mine during the repetetive change of the part, but im not able to exclude it in my troubleshooting. I know i didnt help you at all probably i just wanted to share my very same problem because no one else responded and i might also get help.

Strange black screen issue with fully working screen (electrical, not physical).

Hi,
i bought a factory refurbished I9600F from aliexpress. It worked great for 3 days, then the phone became slow to respond, the screen was flickering in yellow-green tones, and then wouldn't come back on but stay black. (but I would still get notification sounds for incoming messages, the notification LED was still working, and the menu keys also light up when I press home/power).
Pulling the battery fixed the issue once, but the problem came back after 1 hour.
I managed to revive the phone once more by pulling the battery and holding the power button to drain all remaining power in the device. The phone was working again for a few hours, but now it's back to having a black screen and even the power drain method doesn't work anymore...
So i'm guessing that replacing the screen won't fix the issue, since the screen is working just fine for a a while (both image and touch are perfect) - but then somehow there must be some electrical issue that causes the graphics unit to malfunction.
I checked the easily accessible connector to the left side of the battery, but it seems that the screen is mainly connected via flex cables that cannot be accessed unless you heat up your device and pry out the screen.
I have found some information on the internet that pressing hard on the spot where the flex cable connector is might fix the problem, but this didn't work for me.
FYI, I'm running the default Samsung firmware the device shipped with and used Kies + OTA update to get the latest official FW. No rooting or any other mods. Just some regular apps installed.
Any recommendation what I could try to fix this problem? Thank you all!!!

BTW, I have found similar reports on the internet here:
http://forums.androidcentral.com/samsung-galaxy-s5/405238-galaxy-s5-static-screen-won-t-turn.html
But the linked how-to-fix guide states that heating up the display assembly is only recommended on devices with a broken screen... So now I don't want to risk breaking my working screen.

So mainly my options are
a) open the device to check the flex cable connection
b) buy a new battery to see if that solves if (some people have reported success with a different battery)
c) buy a new screen assembly on aliexpress for around €135 and hope that a new screen will fix it...
Thoughts?

sorry, i actually never was able to get this resolved. I tried removing the screen to get to the flex cable, but broke the screen because I hadn't heated up the glue enough...
Had to buy another device.
Sorry I don't have better news...

I'm going find out the cause for this issue. I've disassembled one device that only lights up when it is warm. If I put it in the cooler it refuses to light up for some time after that. I tried placing only the screen in the cooler, also only the phone body in the cooler, but couldn't find any difference doing this as it refuses to light up both times for a couple of minutes then it works great again.
I've ordered another device that had its screen shattered so I will try my current screen on that device.
It could be some internal hardware fault in the mobo, it could be the LCD connector having a bad connection somehow, it could be the screen assembly itself, but I will find out eventually.
I've seen many places on the internet where people say this is a software issue. There is a very simple answer to that question. How could it be a software issue if not even the boot logo shows up when you start the phone?
I will keep this thread updated.

Verified that this is a problem with the motherboard. What circuit on the motherboard could have problems with cold temperatures? The main power one? If so, I will try replacing it with a different one.

Update: Was not able to fix it. Motherboard is now scrap.
