Hello everybody,
I have an HTC Desire that has a problem with the volume buttons. The buttons were working until I dropped it on the floor. The phone had a silicone case and screen protector so it seemed fine until I tried to adjust the volume but it wouldn't work both up and down. I verified the problem by trying to go into the bootloader using vol-down + power but it wouldn't work.
I noticed that before I dropped the phone the volume button was rather fidgety meaning that I could use my thumb to move the button sideways and make it pop out a little bit but despite all that the button worked and I was able to flash LeeDroid on it.
After I dropped it, the button seemed to stabilized. I could no longer pop it out or move it side to side it seemed like the button popped back in and was secure but the function didn't work. I can still hear the click but nothing happened.
So thinking that something was just loose, I decided to void my warranty (if I had one) and disassemble my Desire in order to fix it.
Once I got in I discovered that the volume button was not as simple as it seemed. It appears the "clicker" (the rubber circle piece that makes the click sound) and the actual circuit board that controls the volume is held together on a metal plate with black tape. This means the purple plastic piece has nothing to do with the functionality of the volume key it just pushes the clicker taped to the circuit board.
So I'm confused and stuck on how to fix this. I checked the black ribbon and it seemed to be fine, no tears or anything. I'm wondering how a drop could affect the volume button considering everything is held together with tape including the volume control circuit board and the ribbon that connects it.
Does anyone have any idea how to fix this or anyone know what the volume circuit board looks like without the black tape? I'd like to fix the volume button so I can flash Gingerbread on it.

This is starting to worry me because I had this phone for more than a year and I like how once my 1 year warranty is over, my phone starts to break down. Anyone else know how to replace a failing power button?

Also, the most common form of failure of power buttons on HTC devices in my experience isn't the button itself - it's the little 'ribbon' thing which sits between the switch and the actuator.
It's usually that the ribbon has fallen out of place, become chewed etc. It's tucked in on both sides of the power button, but if one side has come out it can cause a hap-hazard button press.
I found this on the Nexus One, the Sensation and the Amaze. Power button is still good on my Inc 2, but I'd expect it'd be something similar.
Pulling off the actuator, and straightening/re-seating the ribbon should go a long way to restoring the feel of your power button. It's not a hard job, you just need a delicate touch
So after finally fixing all the other issues i had with my phone (broken screen, broken vibrate motor, broken speaker) i was finally at ease. It lasted for about a week with everything functioning until now the phone gods have again struck me down. This time i have what is referred to as a Power Cycle. Kind of like a boot-loop except the phone completely boots up into my homescreen then the power options menu pops up, and no matter if i click back or not, that **** is going to reboot on me. Its to a point where if i pop in the battery the phone auto boots. Here's the kicker though. If i take off the back case and just set it on the battery with an open back, it doesnt power cycle. But the power button on the case itself is not stuck as you may be thinking as i can depress it and the cover spring pushes it back. I've hard reset, even went back to complete stock (no root) and it still does it. the power button works (very sensitive) if you have no case on the back, but if that thing is on, it acts like the button is being pressed.
Any Ideas?
Sounds like the power button is stuck... Try taking the phone apart and cleaning the contacts. Then press the power button a few times to ensure it works like it is supposed to. Put everything back together, tighten the screws but don't torque them. Should not turn on after you put the battery back in, wait a few to make sure it doesn't. Then power it on and see how it goes.

still didnt work. i used some rubbing alcohol and a lint free cloth on it. the interesting thing is, when you take the case off, if you set your finger over where the button is (making no contact) it still registers that you are touching it. this is what i think is causing it to power cycle when the phone case is on, as it believes that it is being pressed when it isnt.

I had almost the exact same problem with my Epic Touch. Ended up being a bad power switch. How handy are you with a soldering iron? If you're pretty good, you can buy the switch for ~$10 and replace it yourself. (You can also try cleaning it - several tutorials here, and the "Captivate" phone seems to have the same switch and issues. Search both forums)
Several eBay sellers sell the switch you'll need.
Finally ran into the constant bootlooping which occurs when the power button is being depressed continuously (defective/sticky power button).
I have found a work around to keep my phone running by removing the plastic power button (not the soldered power switch); my phone stays running and I can use it normally sans a power button.
My question is: how do I know if my power switch is defective/sticky rather than my plastic power button was screwed up and pressing on the power switch in an awkward way (I have dropped my phone a couple times recently).
If it's a defective/sticky power button, I want to get it repaired with mobiletechvideos but I don't want to commit to said path until I know without a doubt I have an issue.

This is almost certainly caused by a bad/stuck power (on/off) switch. It's a very common problem on all the US-carrier Galaxy SII phones. (I think the international "i9100" model uses a different type of switch.)
You can check the switch by gently touching the physical switch (plastic cover/"button" removed) with a toothpick/pen/etc. As a "snap-action" switch, it shouldn't activate until you hear/feel it "snap" closed. If it's activating with a light/slight/tiny touch, the switch is bad. On my Sprint GS2, even the slightest brush against the power button caused it to wake the phone. Sometimes it would stick "on", and then the phone would reboot. I bought a new switch, soldered it in, and have no problems since.
If you don't have insurance coverage and are out of warranty, you can replace the switch yourself. Several eBay sellers offer replacement power switches for the SGH-T989 Galaxy S2. (about ten bucks)
Or, if you don't have mad soldering skills, a few companies offer mail-in repair service:

Hello there nice people of Desire HD's XDA Community,
I have a somehow strange problem regarding my phone. After around 3 years my Volume Down button has stopped working. In order to turn the vol down, i have to push the Up button and then slide the bar down.
This isn't much of a problem but the real problem is that, now, I cannot enter Recovery mode if something goes wrong with my ROM. Has any of you faced something like this in the past?
Thank you for your time
If you're running a custom ROM, it probably has an advanced power menu that will allow you to reboot directly into Recovery. Just hold the power button until the power menu shows up and see what options are available. If you're using 4EXT Recovery, its Control app has a power menu that allows you to reboot into Recovery as well. If you're running CWM or TWRP, perhaps their apps have a similar option.
If your phone is off you can try connecting it to your computer and using adb to boot directly into recovery,
adb reboot recovery
hey sharksfan7... Thank you for your answers. I am familiar with all of these functions.
I was asking for something in case of the phone does not boot and there is no PC available.
Or even if some user had the same problem before and can recommend me something he/she did. Like, replace the volume rocker (although I don't think a piece of plastic is the issue. More likely some "sensor" is fried/broken)
Again, thank you for your time
If the phone won't boot, you probably need a computer.
Hi there
My vol +/- plastic broke and fell out so when i need vol down + power i use toothpick , but just before it fell out completly i noticed button has 3 pads 2 for pressing buttons and one in middle for rocking action and that one fell out completly first and after that neither vol buttons using palstic button worked, so after a while it fell out completly and i discoverwd toothpick method.
So check if buttons work when you remove big plastic bar if they do see if pads are on place, biggest black is in middle, 2 smaller for pressing near end. Or just replace whole button.

Need help in buying a new volume button...
I'm searching on ebay for a new volume button, but can't seem to decide on which one can be the best... Don't seem that most are genuine (if any at all), but I don't expect that...
Can anyone help me on this? http://www.ebay.co.uk/sch/i.html?_s..._nkw=htc+desire+hd+volume+button&LH_PrefLoc=2
When I install the new one, does it going to stay firmly attached?!?
I'm asking this, cause on the last time that I dismantle the volume button, I don't know what I did, but I never got back the volume button firmly attached again as it used to be. Now it's very loosely and it very simple to loose it from the phone and that's why I'm buying a new one... to trying to fix the volume button to work and to get it firmly attached on the phone.
Hi there,
I've got the same problem here, but my volume buttons are gone..
I've ordered one from good old china (hehe).
I think you have to set a piece of elastic glue in the center of the button to keep it in place.
At least at my phone there is a little point of glue-like stuff there, very elastic.

but do I have to put that elastic glue or does it already come with the new button that you order??
Did you already have that new button and put it on the DHD ?? If yes is it good and fits good? Where did you bought them (ebay? seller?)

Not arrived yet, will tell you then.
I think you have to organize the glue yourself..
Any news??
Yeah. Arrived this week, I just installed it. No glue delivered with the parts. And the parts aren't nearly the original, but I got two of them.
Because I'm using a cover, the volume keys didn't disappear until now.
Just took a long time to get them, next time I'm gonna spend 3-4 EUR more and order it from Germany...
Hello
I'm having an issue with the volume button too, so I'm using this thread.
I have only the down volume which is working, the up button doesn't respond whatever the ROM.
And now the button doesn't stand in place, I have to watch when i take it that the button volume stay still. (I may use some glue to fix as you wrote earlier)
Do you know what I have to change if the up is really down ?
I don't think my button is wrong, but maybe I'm wrong and there is some contact to chek before going further ?
Thank you for any help !
I had a weird thing happen. Earlier today I dropped my phone from approximately 18 inches onto a laminate surface. The phone was in a protective case. After I picked it up, the power button wouldn't work. The rest of the phone was fine. No scrathes on the case, no other types of hardware failure or signs of damage. I opened the phone up, removed the motherboard and inspected the entire system. Everything seemed perfect. I inspected the power button and there didn't seem to be an issue. I put everything back together, while paying close attention to make sure that all connections were secure. After reassembly there was still no change. So I have a couple of questions:
1. Can I jump the connection between the two power button connections (which I believe is how the power button itself normally activates the phone) to see if that's where the problem is so that I can establish if the power button is in fact the problem? Or will that short something out on the motherboard?
2. Has anyone had anything like this happen, or know of a place where the power button can be bought, etc... Any suggestons are appreciated! =)
Thanks!
Edit: I was able to find the connections to the power button flex cable. The two terminals were loose and I was able to pull them out a bit using a wooden tooth pick. I now have good contact and the power button is working perfectly. I recorded what I did and will post a video on YouTube in case someone ever has this happen to them. I don't know why an 18 inch fall would cause this type of issue, but oh well. Fixed is fixed.
