Broken power button - Defy Q&A, Help & Troubleshooting

Hello,
Recently I found my father's old Moto Defy and I think it would be nice as backup phone, considering it has cm7 available. It would be great if the power button worked, though. Is there anything I could do about that right now or would I have to replace whole motherboard for this phone to work?

mine fall off my hand and now doesn't work, I disassembly and the switch was slided, I manually moved back to front and i works, just for a short time. I guess it has to be soldering again... btw with CM you can unlock screen with volume keys

Faulty volume button

Couple of days ago I noticed that my DHD's volume down button does'nt work anymore. First I didn't pay attention, thought that after restart it will be solved, but it didn't. The volume down function doesn't work in any software (up works just fine). Before I decide to go to warranty, what do you think, is it a software or hardware problem? There is no accidents or any damages happened, I know and physically the button seems to work. Please help!
Normally buttons are hardware, in your case its easy to tell.
remove the battery. Put it back in. Hold down the volume down then turn on the phone, if it starts normally your button is dead, if you get into bootloader mode it could be software and you should try reflash or wipe in settings

Thank you so much Blackhorse!
Although the first try didn't succeed (perhaps I didn't hold both volume down and power button long enough), the second try started the bootloader and I was able to use both volume buttons. After another boot the stock rom started normally and now my volume down function is back! Hopefully it stays so...
Hey guys,
My volume keys have died. Part of the wire strip that is connect to the buttons is torn.
Any ideas if there is a replacement upperboard yet?
having the same issue... going to try blackhorse's solution and see if it works
best regard

unfortunately it didn't work. I guess the volue down button is dead, even though I had absolutely no accidents with it.
does anybody have an idea of how to solve this, since I live in Brazil, but bought DHD in Germany?
any help would be very appreciated
best regards
André
same problem here, my buttons stop working. What I usually do then is lift the volume keys up slightly and slide some paper underneath to clean some dust and then usually it works again (for a while)

[Q] Milestone 2 power button repair

Hello there guys!
Recently my M2 power button stopped working, there is no click whatsoever. I checked it up and it seems that the small metal piece fell somewhere inside the phone. I found this dissasembly video : http://www.youtube.com/watch?v=BUXSmlwUC9Q
Now here is my question : it looks like while dissasembling you are ripping the phone apart, is there any permanent damage when trying to dissasemble? I could do it by myself, pasting the metal piece inside but I m a bit concerned about damaging the phone.
Thanks
Strange Milestone 2 power button problem
Hi, I have a strange problem in the power button too, but it's very rare (may be rare just for me)
The thing is that the power button suddenly stops working. If i take off the battery and put it again the phone boots without pressing the power button, and it still not working. Then after some time, it suddenly starts working perfect there is no need to press it stronger then normal.
I can't find out any patterns in this behavior. Another strange thing that happens is that sometimes the button works intermittently and delayed. Example: I do a long press of the power button and nothing happen, then the shutdown dialog shows 2 seconds after. And some times (the most) it doesn't
I'm a little bit confused about it, any ideas?
I've new info: i can't get into bootloader mode (the phone turns on but i get a black screen with no text)
Think I am getting the same power button problem now. How did your repair go?
Same problem here now, dunno if its really related to the power button or something
completely different is going to break down soon.
I will try to replace the whole flex cable with the buttons, but shipping needs some weeks.

[q] my motorola defy side button and power button is not working

My motorola defy side button and power button is not working ,i asked in motorola service center the guys tell it hard to get tat spare parts .i search e bay and other online site ,please guys help me to get tat defy spare parts buttons
Are you missing those buttons or are they just not working? 'cause if they are not working, you need to replace the motherboard, in order to get working buttons. Don't think it's worth it - better buy a new phone.

My Defy's volume up button stopped working some time ago. It was quite annoying as I used the volume buttons to unlock the phone. Some time later, I pressed the button really hard, and to my surprise is started working again. And like that I had my button back

It has nothing to do with the motherboard. There are soft silicon membranes in the cover for water resistance. These are wearing out after some time - always!
They can be replaced or you can make new ones by yourself. I did successfully.
After flooding mainly top of the phone, and cleaned in alcohol. Power button does not work Is it possible to exchange the key? Unauthorized GSM service can handle this?

[Help] Volume buttons dead, even after rocker replacement

My dhd volume buttons stopped working a while ago (unless u press really hard). I ordered a new button and it arrived a month later, now even with the new button, they r not working .
Also pushing the buttons with a pencil tip (without the volume rocker) still doesn't make it respond easily...almost completely dead
What am I supposed to do to fix it? DIY possible? Any suggestions are much appreciated.
Hey look buddy. I had the same problem and I have resolved it by replacing, by myself, the mother board were the volume buttons were attached . It's a DIY thing. Just order from ebay or any local mobile service parts from your country, the upper main board ( upper mother board ) and then search on youtube, how to disassemble the phone. Just to be very careful when you open up your phone because it's a little tricky, and remember the order of your steps.
Good luck !

[Q] Phone only boots into safe mode because volume rocker broken

Help guys, my phone went swimming in the sea. I turned it off immediately and let it dry off, but the volume rocker doesn't seem to be working anymore. It does not react to my touches, but is constantly pressing VolUp or VolDown (I can't tell which one).
When I first started it, I got a bootloop, so I went into recovery and reflashed my ROM. It is booting now, but only in safe mode (since the volume rocker is constantly pressing). Is there any way to disable safe mode, maybe via adb or something? Or to disable the volume keys software-side?
The OS is Jelly Bean by the way (not that it matters). Everything else is working perfectly fine.

Probably, you'll need to pull the phone apart, and either clean, or replace the small volume rocker board. You can find them on eBay for pretty cheap. It's usually only a last resort to look for software fixes for hardware issues. The Nexus 4 is relatively easy to disassemble and replace parts, since everything is modular. I don't know if you have Radio Shack or an equivalent in Germany, but there's a duo of products called DeOxit and ProGold. DeOxit cleans contacts (silver, copper) from oxidation, and ProGold increases conductivity. This might be enough to clean your volume board contacts enough to work without replacing it. Of course, it is possible that the logic board is damaged, in which case you might be screwed. Replacement motherboards cost as much as a used phone does.
To be honest with you falling in the sea usually means a dead phone, saltwater is highly corrosive.

Thanks, I'll try that. Can you tell me how the screw type of the Nexus 4 is called? So I know what screwdriver to buy.
torx 5 on the bottom, you need a small phillips for the inside screws.
