power button not working

I have a problem with the power button on my desire, the phone wont switch on.
I have taken the phone apart but cant see any physical problem.
The phone still charges ok.
Is there anyway to get a stock phone powered on without the power button.
Does it sound like it might be a faulty flexi cable.
Or any other advise.

you might need to take phone to repair center sounds like something a phone repair ceter can fix , i dont think there is a way of turning on the device with any other button ( i think it's possible if you changed it if you rooted but in your case i dont think so) does the cable near the power button look burnt out or loose , did you drop your phone ?
btw what are your usage patterns ?

The power button is hardwired. You can change the function of hardwired buttons using software, but software needs to be running/on to do that. You cannot use software to redirect the function of a hardware button with the software not running/off.

I have managed to switch the phone on using the usb trick, and the power button is working. Guess i will be ordering a new flexi cable

sounds like you need a new device

Volume up, Menu and Home key not working!

Hello everybody! My htc desire's physical buttons(actually just the volume up, home and menu keys) don't work...I press them but nothing happens. Well, they work sometimes, but when they don't I reboot my phone, randomly press some buttons, and they start working again. I just don't know what the fault is. Im on MildWild CM 4.3. I think the same problem was with other firmwares too. Can you please solve my problem?

If your device is under warrantly just send it to htc. It's a hardware problem, not something that you can solve with a script.

Ah, so you're telling me there's nothing that can be done to repair it? Cuz, my device isn't in warranty(I just replaced the casing)...

I don't know.. I don't want to be pessimistic, maybe you can search for similar problem in internet and a possibile solution, not just for Desire but in general for devices that have hardkeys. Maybe like use a spray for electric contacts while device is turn off and wait that it's completly dry before turn it on. Good luck.

I can't remember it, but I think that this problem appeared only after I got my casing changed. Could the technician have done something wrong? Can I send it to the man that changed the casing?

It's probably just some dust that gathered underneath the buttons. I had the same problem with the volume down button. I used a needle to clean the dust around it, and then it worked perfectly.

I dont think it could be due to the dust, cuz there are three buttons which simultaneously stop and start working... It's a bit strange tho..

I have issues now with my power button. It's unreliable... that is, the button sometimes works. Sometimes when I press it, it opens the shutdown menu..
Started all of a sudden. Not sure how that happened... and it's out of warrenty for 4 months now..

That is why I use Button Savior

Same!
I am getting the same problem. I have replaced the keypad flex with a new one and still getting the same issue. It would start working randomly like if I open the browser and open many tabs, then it would work. Funny thing is that they would not even work when I go in recovery.
My desire is 2yrs old now but I still love it.

Same problem here.
Mostly happens with Home and menù. Less often with volume buttons.
For now I'm using the "button saviour app" workaround, but if is something hardware I will know it very soon... (made a copy of my rom on a friend's HTC Desire)

All three buttons simultaneously! Buttons usually fail gradually one by one and drive you mad finally. I would put my money on the keypads being misaligned during whatever you got done with casing. Take it back to him.
If its some kind of misalignment no amount of sprays will help.
BTW I use zmooth for button conservation

use soft key instead

I had the same issues : menu button working randomly, had to press very strong on up/down volume buttons.
I've dismounted my phone (using this : http://www.formymobile.co.uk/desiredisassembly.php ), and I saw that there were a lot of dust, hairs.. I tried to clean up/down volume buttons the best way I could, and they both work so much better now! Not totally perfect though.
By the way, I noticed that there was a lot of compressed dust in micro-USB connector and was able to remove it fully (thing I couldn't do without dismounting phone).
I didn't want to go farther to access menu/home buttons because I didn't have time and Menu button works quite OK.

I have the same issue here with the volume buttons they tend to get unresponsive and unreliable.
Even though all the parts were renewed since six months ago, the volume buttons are probably bad designed?

You could replace bad working buttons' functions with others'. My volume down isn't working, so I made my search button act like a vol down.

Buy the new one

[SOLVED] "SAFE MODE" overlay bottom left, HELP !

Hi guys,
I've been on xda for a long time and done all things on my trusty old desire, but recently, during a rainy day, i tried to listen to a call, and maybe some water got in..... I went turned off, went home, dried the phone for a couple of hours,
Now when i turned it on, there is a message overlay on bottom left of screen, :SAFE MODE:
SAFE mode disables your DATA partition and no other obvious side effects (but its a big problem itself)
I've googled i around and some say its hardware fault, some say they fixed it with some keypress combos.... i tried em all, no luck yet..... keys do work in rom, except the Vol down, trackpad, and power key(it reboots instead locking).
I tried several gb, ics roms, downgraded hboot, then upgraded, many wipes, many reboots...no luck as of now..... Any helpful suggessions are welcome. I love my desire very much and plan to use it (if repaired) for a year atleast....
If there is a workaround, tell me ill try it for sure. My phone out of warranty so i am also willing to open it up myself and in that respect, any guide or tutorial is also welcome. Please guys just anything, even for the sake of it. (i know i sound desperate, coz i really am. Being a student, u cant replace smartphones very easily)
Regards
A broken Desire owner:crying::crying::crying:

It seems your Vol down and trackpad are stuck, so they keep being pressed. Might be a contact problem, but might also be on the mainboard.

ok guys
Lets see,
I opened up my desire using a disassembly video, (pretty hard job finding right screw drivers).....
Now vol down, vol up working..... power key is acting normal (not rebooting the phone on key press),
Search, menu, home, back, all are working perfect......
Optical J-pad NOT working, not pressing, not moving,
And phone still in safe mode....
Now any tips !!!!
Regards
Yasir

Usually you'd go to safe mode when pressing the menu button while booting, but it may be the same with the trackpad (can't test that atm). You say menu button works fine? Try pressing Vol- and Power and see if it reboots, then your trackpad is still stuck (and you can probably fix it like you fixed the volume buttons).

thanks for reply
hi,
OK guys i have some update....
Desire can be put in safe mode by using MENU + POWER key combo, thats the normal process. BUT, if there is water stuck in ANY of the keys, may it be vol up/down, menu, home, optical joypad etc, the DESIRE will detect a Fault in hardware, and go in SAFE MODE ALWAYS, no matter whether u press a combo or not....
IN MY CASE, the optical joypad had the shortcircuit...... i opened my phone myself using a disassembly video, and cud clearly see the burn out wire in optical joypad. So i removed the optical joypad button cable from its connector.
For the rest of the keys, i JUST performed cleaning with cotton cloth, and packed the phone up.
Voila !!!! The phone booted up JUST FINE......
so for all you guys out there, if you encounter this, you know what to do.....
I'll attach the picture of removed OJ later.
Regards
Yasir

[Q] Root HTC desire HD without volume key

I have searched everywhere for this and cannot find an answer so I'm sorry in advance if I have missed it somewhere. I am just bought a htc desire hd off a friend with the intention of rooting it but didn't realise the volume keys were broken. I have tried to reboot it into recovery via ADB but it gets stuck on the screen with the phone and a red exclamation mark in a triangle. I have read on other posts that this happens when you go into recovery and you press power and volume up.
Obviously I cannot use volume up so is there anyway to get around this or to avoid the screen in the first place? Or is there another way to root I'm missing where I don't need the volume keys? Even if I get into recovery mode I cannot change the options without the volume buttons.
Any help is appreciated.
Thanks

I would strongly, strongly advise getting your volume keys replaced and/or fixed before attempting to root. You can get very very stuck trying to root without working volume keys.

I actually had this problem. Wanted to use aahk and I couldn't downgrade ruu because my volume up button doesn't work. I ended up pulling off the volume rocker. Then I used a screwdriver to press the button and it luckily worked. If you can do that, that could be something you could do. But be very careful when removing the rocker or you could break it. Mine broke. But I have a otter box so its all good. Also, if you're going to get a recovery, I highly recommend getting a touch recovery like twrp or 4 ext so you don't have to use the volume buttons in recovery.

Thanks for the replied. Only paid £20 for it so not massively bothered it I break it. I've tried to do that with the volume but I don't think it's the rocker thats broken I think it's the part inside and wouldn't know how to replace it! Just thought there may be some way to get around using volume keys altogether haha

Anyone got any other ideas?

check ebay and buy a replacement volume key. They are very cheap and there are videos on youtube describing how to remove and replace it.

It's not actually the key, I've pulled the inside volume chip out (the bit behind the button which gets pressed) and pressed them and it still doesn't change the volume so I think it must be some sort of problem with the chip or the wires. I don't really know what that's called to search for on ebay haha

I am in pretty much the exact same Sh*t at the moment. However I have something even more problematic, I lost the volume rocker ages ago and I am still trying to work out whether the button itself is dead or if I am simply pressing this volume chip incorrectly. :/

If you use the end of a paperclip and try and press where the rocker was you should feel a little click as you press it in meaning it should still work. I do this with one of my Desire HD's.

Thanks for the responce (Umm)

Umm I have tried many things so far and I also find that the volume up button is not pressing. I am not sure if it is pressed in or what but the volume down button does press down (clicks when you push it) but the phone never seems to register it as a button press :/

Sounds like your stuck then. pardon the pun

Well the same as i, but u could quick boot to go to recovery

BTW I have an update on my situation. The - volume button definitely works however I think the + button is dead. However I still can't seem to get the phone in recovery by pressing power and - volume button. All I see is the T-Mobile screen and then HTC logo. Any ideas people?

[Q] Power button hyper-sensitive

Hi all,
I've had some problems with my S3 power button. It's behaving like it's being pressed when it isn't. Just slightly brushing it, without depressing the button, is registering a press. Pressing the button is behaving like the button is being held.
I've read a number of possible fixes. I tried software options, just to be sure (cleared cache, factory reset). But this is almost certainly a hardware problem.
I stripped the phone down and the physical button itself looks absolutely fine. It is interacting as it should with the internal button on the motherboard. The issue seems to be that the internal button attached to the motherboard (the little white button) is registering clicks even when it's not being fully depressed.
The phone did have some water damage about 6 months ago. I wonder if this could be causing the the phone to mess up now?
I even tried a fix that many people seem to think works: smacking the crap out of the power button itself. It had no affect on my phone - I think that "fix" that is for a power button that is stuck depressed and not a power button registering phantom clicks/being hyper-sensitive.
So I suppose I have the following questions:
1) Has anyone else experienced similar problems and, if so, did they get it fixed?
2) My plan is to try replacing the motherboard/logic board and see if that helps. Does that sound like the best fix or is it overkill?
3) If I'm replacing the motherboard, does it need to be an I747 motherboard or will any S3 model work fine?
4) What's the best source for a motherboard? I don't mind if they're used or refub so long as they work.
Any advice you can offer is welcome.
Cheers.

I had the exact same problem with mine, and unfortunately there's not much you can do about it as it's a hardware defect. I haven't tried replacing motherboards or anything, so that might help you. What I did to help with the problem was rerouting my power button to my volume up key so that I can use the power button as little as possible. The only time I use the power button now is when I need to power it on - which causes reboot loops sometimes.

Sucks.
I like the sound of your work around, though. Was it pretty simple rerouting the power button?

Ditto, my power button is borked too. Ended up doing the same thing but I don't use my power button at all. I just use rom toolbox to reboot system/into recovery
Rerouting was simple for me as it's baked into the settings in the rom I'm on (ground zero) as it is with most custom ROM'S I've been on. If you're just running stock I'm sure there's an app in the market that'll work however I'm drawing a blank ATM

I'm running CM.
I've had a look through the routing options. What I can't locate is a way to disable the power button completely. My main problem right now is the phantom clicks. I'd rather that button be dead.
Anyone know of a way I can make that happen in CM?

Nevermind. I just physically removed the power button. That did the trick.
For anyone interested, you can replace a faulty power button on the motherboard pretty easily and the parts are cheap. If I wasn't due an upgrade in 4 months I'd probably do that. No need to replace the whole motherboard.

Does anyone know the app to reroute the button? I too have the same problem.
