[Q] Turn phone on without a Power Button. - LG Optimus 4X HD

Hi, My LG P880 has a broken power button. I got around the use of it via the Gravity Unlock app but recently my phone died due to low battery.
I tried to plug in, take battery out and put it back in.
I tried plugin it in without the battery.
I tried plugin it in with battery and then take the cable out once it display.
All three ends up with the battery charging indicator after the LG logo and then turn off.
I need some help as I am hoping to hold onto this phone till my contract status is available for a change in handset.
Any help is appreciated.
PS: My phone is unrooted and without any modifications etc.

If your battery isn't holding charge buy a new one no?

I think the problem here is not the battery She needs a way to turn on her phone without having to use the power button.
OP, what about warranty?

Without modifications there's no way I think. Adb needs drivers and Dev settings set properly to turn on the device from a connected PC.
I would also suggest to go for warranty if you're able to.

Thanks for the reply, though it does not solve my problem, it is still very much appreciated.
It's is not the battery, since it is detected when plugging in the charger. It is even at full charge.
Warranty wise, It is kinda expired since I am on a 2 year contract plan with my telecom which ends this August and I am sure that the warranty is only for the first year.
The phone still can't be turned on after more futile attempts and I had to resort to using a backup phone that has no data capabilities.. sigh.
Will consider sending it to a repair shop once I get enough funds though and again, thanks for the help!

What exactly is wrong with your power button? Perhaps you could try removing it and use something thin to push the actual button underneath it?

In my opinion don't touch your phones hardware parts don't even think about disasembly.... just take it to some repair shop if its out of warranty fixing the button probably will cost you 15-25E How much could replacing some tiniy button cost :fingers-crossed:

that thread is quite old though, but I found an easy solution. Maybe it helps someone out there...
you need some skills with electronics or at least with small parts and screws and I am not responsible if you damage your phone.
But anyway, your Phone doesn't work anymore and there is no warranty anymore, so why don't you just try it.
There are youtube videos how to disassemble it. but just when you got rid of the back cover and the electonics is uncovered, you need to pull out the flex cable that leads to the power button. Pull it out gently (it's not glued) and check it out. in my case there wasn't any visible damage and it still clicked as if it was working (but it wasn't).
Well, that click-thing in the end of that cable can be devided into two parts such as the contacts (on the cable) and a bowed piece of metal that is taped on them and supposed to make a contact beween these two contacts when you press it. I separated these two parts and cleaned it with an alcohol pad, afterwards I just put it back together without any aditional glue. Make sure it clicks again as before, also when you put it back in place and close your phone again.
Make sure, you do have a working battery. if your phone died half a year ago because it ran out of battery, and you didn't charge it again, the battery might be completely empty and therefore dead.
hope that someone can make use of my simple howto. Greets

[Q] power / lock button wont work

My captivate power button is stuck. Once i put my battery in it turns on i can get to clock work but its no use cause i cant select anything. Ive been running this rom for a while now and havent had a problem. Has anyone had this same problem? Is there anyway to fix it or do i need to get a new phone?
Thanks
What ROM are you running? Have you tried asking in that thread?
Does the button actually depress or are we talking physically stuck? You could always try 'adb reboot recovery' and installing a different kernel.
You installed a I9000 ROM didn't you?
Hold up+down volume buttons and insert usb cable while phone is off. Should bring you to recovery mode where you can one-click ODIN back to stock.
The power button is not replaceable on the i897. My advice is to open the phone up and slowly work the button with a pair of tweezers. I'd use a small can of white lithium grease and squeeze the smallest bit you can near the button to smooth the operation then re-assemble. Or if you under warranty, just ODIN back and send the phone in.
I was running continuum 5.5 GB, but thats not the problem cause i managed to flash back to stock and its still a problem. I had the back of the phone off and the button is clicking fine so either the button went bad or something stuck inside. I went to at&t today and they say no one on my plan has a upgrade available. So this blows, I'm gonna go to a customer service place tomorrow to see if they can do anything. Somehow i never had insurance on it so again that sucks.
Is there anything else i should do before i go to customer service I'm back to stock and i took all my pics and everything off of it. I also installed some apps and set up my widgets and stuff to look like it hasnt been modded.
You can always get a warranty replacement.

I dont have a warranty though
Samsung warranty is one year and the phone's release was less than that. Have you tried calling Samsung?

Why do you not have warranty?
Oh ok sweet, didnt know it had a factory warranty for that long. I meant i didnt have a warranty through AT&T. Im gonna go up to the customer service att tomorrow morning, let them know it has a factory warranty, and see if they can do anything quicker. If not ill call Samsung.
Thanks everyone. I'll let you guys know what happens tomorrow.
AT&T has repair centers that can replace the phone.

my buttons were sticking to on my Samsung Captivate , it got to the point where the power button was no longer working and my cappy was out of warranty. I just decided to take my captivate apart and disassemble it (i used this video http://www.youtube.com/watch?v=2y8mRCcQ4jo ) and then i located the power button and used some " CRC QD Electronic Cleaner " and just sprayed it directly into the power button (when i say "spray" i mean i pushed the spray button for about 1 second). After spraying it i pressed the button like 20 times, then i sprayed some more and while spraying (spray for 1 second) i was pushing the button about another 20-30 times. I repeated the spray and push cycle about 10 times (which means i probably pressed the power button over 300 times ), I waited about 5 mins to make sure it was "dry" and then i put the battery back in and test it and It seemed to have cleaned it out and now my power button worked. Then i put everything back together.
Note: I tried to spray and press it with the cappy with the enclosure/case/body on but the button cover blocks the actual button and i was forced to actually disassemble the case, its not to hard just looks intimidating. whole process took me about 45 mins first time.
Note 2: CRC QD Electronic Cleaner can also be found at most local auto parts stores BE SURE TO GET THAT BRAND as it is non-conductive, i repeat GET THAT EXACT BRAND/MODEL Cleaner, cheaper brands might be conductive despite it saying it is safe or does not dry as fast and who knows what might happen, CRC is a known well brand and has a good rep)
samsung captive
I did this and it brought me to the screen downloading and it says dont turn off target and the little adroid is shoveling..is there anything i can do at this point?

i have searched around some things to try to power on the phone....
but unfortunately, i cant test them as they might not work and i would not have a way to power on the phone.

I brought it back to the service center. The putting pressure method only works for a small time and is unreliable. Eventually my entire powerbutton stopped working and I couldn't charge my phone anymore. I suggest you bring your phone to a service center before it gets worse.
Guys,
I have the same problem and I ended up opening my phone to see what is going on.
Basically, there is a bus (a group of cables) that comes from the power button, usb port and ear speaker and is connected to the motherboard exactly in the area where you apply the pressure, more or less around the LG logo.
The connection of this bus is done using a 14 pin dual inline package.
What happened in my phone, I assume it is the same in yours, the base on the motherboard where this bus is connected got disconnected, it lost the solder around the pins and the connection it has with the board is loose.
I will try to provide a picture the next time I open my phone..
When you apply pressure, what happens is that you fix the connection so the button works.
In my case, the whole base got disconnected and there is no way to solder it back manually because it is surface mount and it is extremely tiny, you can barely see it with bare eyes, but it might be done using a microscope although I doubt it due to the crowding of the components in that area.
What I did was to put some papers behind it to increase the pressure, but it was a temporary solution.
At the moment, the button works only with pressure, I cannot use the ear speaker (it is dead), and the usb port only supports charging and no data transfer.
I do not know why LG uses such low quality components.. but what can I say?
Be careful guys, it might get worse with time, make sure you do not let ur phones fall or receive hits.
Good luck!
I have the same problem, usb connector and speaker is ok, both are in the same cable flex with the power button,
the only way to power up without the button that i found is:
1.-remove the battery
2.-press and hold volume + and connect usb to charger or pc (the software update screen is displayed)
3.- insert battery, then disconnect usb (the software update still show up)
4.-here you need to be quick, remove and insert the battery quickly
after that's the phone restarts.

Power Down Freeze?

Okay guys so I know that there are a ton of threads discussing the issue of not being able to power down the Captivate. What I haven't seen are alternative solutions. Like if I broke the power button off the mobo would this tear my phone up completely or would it stop the phone from thinking it was constantly being stuck. I did the key test and didn't see it as stuck or being pressed yet when I remove and insert my battery it turns on. Is there anything else I can do other than paying money I don't have to fix it? I tried the CRC cleaning method like six times and nothing. Please try and think of other ways to fix this. I have MANUALLY remapped the Volume Up button to be the power button and when I select power down it starts to power down then vibrates and freezes. Also if the phone is plugged in I can get it to power down to the battery charging screen yet when I unplug it, it powers on. I know you guys are extremely smart so I'm sure we can find a fix to the freezing when powering down without shipping our phones off.

The crc method works most of the time for me. One of my Cappys the crc didnt work on and since it was a spare I wasn't gentle with it. I took the mainboard out of the phone and holding it I smacked the exposed button on the corner of a table a few times and haven't had an issue since....and yeah, it's pretty easy to rip it off too if you just want to break connection....On an old board, since the button is so small I just ripped off the button and soldered small wires to the contacts and attached an external button...looked funny but it worked....

Also, when I use the crc, I take out the mainboard and use the crc straw extension to push in the button and spray like that so it can really get inside the button casing. Then I tap the button rapidly off a table or a wood block....good luck, I know it's a pain...

If I break it off though and put nothing in its place will I still be able to use my phone? Also if I'll still be able to use my phone with the button gone will I then be able to power it off with out it freezing?

I used mine no problem with the button pulled off of it. I turned it on one of two ways. Either with a failed jig I made that wasn't quite enough resistance to put it into download mode, but when I inserted it it would just power on the phone, or I would use a cable I made for dock mode which would also power on the phone.....As far as actually freezing when powering down, I have only seen that on one of my phones running gamerz rom. Usually when the button is stuck it just restarts after you power it off, but for me with gamerz rom, it instead was just locking up and the screen would stay on till a battery pull, or holding volume buttons and power button for about 5 seconds.(actually I just held the volume buttons since the power was stuck on).
In short though, if you pull the battery and put it back in and the phone boots up on its own, it is definitely the button stuck on.
Yes mine is stuck on and I want it to stop so I guess I'm ripping the button off haha

lol before you rip it off, you may as well try hitting the button against something a few times to see if it helps....you would be better off with a power button than trying methods through the usb to power it on from a powered down state. Besides, to rip it off means you gotta take out the main board anyway, so it may be worth a shot.....If you do just rip it off the board, you can find a thread here on resister values to make a usb dongle that will turn the phone on.
Just saw your other thread about a jig so you have the resistors and probably the thread too....If you have any doubt about resistors and about any other electrical components I recommend an app called electrodroid. it has a free version and is very handy in helping with resistor values and the color coding.
I can CONFIRM that taking out the main board and CAREFULLY prying the power button off or using small pliers DOES stop the phone from freezing on power down and I ALSO found out that my Download mode three button combo now works!!! So if you're in a pinch for money and your power button is stuck in the ON position and need to flash back to stock or need download mode to work. This is a great temporary fix. Then when you get the cash just order your button and have someone that's good at Soldering solder it on for ya.

Having a sim card or not in your android doesn't affect wifi at all. You can still use the internet.

Which part would I need to order to get the external power button?

I picked up a Nexus One off of swappa, with the power button issue. Thinking it was the flex cable issue, I ordered a replacement off of eBay (it was new). Got it installed, and the power button still doesn't work. But when I was disassembling the phone, I noticed the external power button did not have much travel in it, and didn't offer much in the way of "clicky-ness" for lack of a better word. Plus, only one side of the button would stay in the housing when the phone was disassembled. That leads me to think the button itself is the issue. Searching for replacement parts does not yield a supply of buttons. I'm sure there's one out there somewhere. I can still turn it on via the "plug in, take out battery, wait for led light to go out, put battery back in" method, but I'd like to have it just work like it's supposed to. I'm hoping the internet can come through for me here. Thanks.
I know there is an app that let you use the search button and the trackball to turn off and on your screen

HTC One stone dead!! Please help!!

Hi,
I recently went on vacation taking my 11-month old HTC One with me. Everything was working fine until one afternoon I went for a swim and returned, only to find my phone not switching on. That was puzzling, since it had about 50% charge left, and I was gone only for about 30 minutes, keeping the phone in my bag. I returned to my room and kept it on charge. No blinking red LED, no solid LED, nothing. Started to panic and tried various solutions specified here, all button combos I knew of (Power, Power+Vol Up, Power+Vol Down, Power +Vol Up+Vol Down, Light trick), but nothing worked. Connected phone to PC, and could hear the familiar 'USB Connected' sound, but nothing else apart from that, no storage device detection, nothing. Tried ADB, fastboot but since device is not being detected, they're useless. Kept it on charge for the whole night, still no response.
Decided to sent it in to HTC Service Centre, guess what, they call me back and say there's LIQUID DAMAGE to my phone's motherboard and I'll have to choke up Rs.14500 (around $250) to get it repaired. I argued vehemently that the phone was nowhere near water but to no avail. I took the phone back from them and was by now totally in despair. Kept it in rice for 2 days, still nothing. Tried out a local repair shop but the guy there has no idea about single case phones. My phone has everything stock, stock ROM, stock Sense OS and with Android 4.3 updated. I am really at my wits end now, and can't afford to pay that much, particularly considering the amount I had to cough up to get it. Guys, please HELP!! :crying:

I don't think we can help you with hardware damage. Your phone's motherboard is dead... from liquid damage or not idk but the fact is that it must be replaced and you have to pay someone to do the job or buy the part and fix it yourself if you have the high level skills required.
Sorry ;(

I did try that as I specified above, held the device with Vol Up + Power, Vol Down + Power under a bright CFL light (tube), no response.
Try plugging it into a USB port ..leave it for about an hour...and then unplug and immediately plug it back into a wall socket..and while it's plugged in, try powering it up after about 10 mins...I've seen this working more times than one for the Galaxy Tab 3..no harm in trying it out.
On a lighter note, are you sure you didn't take the One along for the swim ??

Nothing has worked. I really don't seem to have any choice now but to give in the phone for repair.
