I would like to thank everybody who answered and gave me the courage to open this phone and repair my power button by myself !!
The power button shown in second post was not working properly
It has two pins which short the PCB and the screen gets on
my power button was not able to provide a path for current to flow when it was pressed .
so i opened the phone , took out the power button
the power button has some tape over it so removed the tape
i saw that Power button had two rings and a circular metal plate which connects the two rings so that current can pass when pressed
I repositioned the metal plate so that it can completely cover the two rings and again put some tape on the ring .
and also expanded the two golden pins on the power button so that they can touch PCB easily
I reassembled the phone and tried to press the power button and it started working !!! :laugh::laugh::laugh::laugh::laugh::laugh:
but the power button is very weak as compared to what i had earlier but I am afraid that the problem could return in future !!
Here is what had happened !!
My phone's power button is not working
Nothing happens when I press it
I was reapplying my wet screen protector and after that when I tried to press the power button I noticed that the power button is not working Maybe some soap water has entered the device or I might have pressed the phone too hard in order too remove the excess water
so I tried to put it under hairdryer after that for 10 mins but no results
The phone is running I connected the phone to charger and the screen turned on showed 56% battery remaining
I am able to use the phone touch is working everything else is working
Today I went to a technician ,he opened my device and told me that there is some shorted in PCB but I dont trust him
He tried to touch these two contacts ( the upper circle ) at the same time with a Tweezers and the power menu came and screen turned off

A reply from a senior member or recognised member will be highly appreciated
Sounds like some on the water (or whatever you used to apply the screen protector) got inside the phone, and damaged the switch.
Since your phone is still working, and reponds on connecting the two contact points, i assume the water did not damage the motherboard.
Seems like you need to buy a replacement switch. Google it or look on Ebay for it.

This^^^. Also if you don't feel comfortable replacing/repairing it yourself, you can RMA it.
Hopefully you can get it fixed, just make sure that next time that you try to apply a wet application screen protector you leave the device off for at least 12 hours. Apply it over night.

If it is water damage I can't see it being accepted for rma
Sent from my Nexus 4 using xda premium
take that power button out and dip it in isopropyl alcohol/petrol,clean dry it with a brush/cloth and place it back,see if that brings it back to life..
Is this true ?
Thanks
I went to Technician .He opened the phone and did almost nothing
He told me that PCB is shorted but if so then how come everything else is working other than power button ?
Can the can the phone be fully working other than the power button when the PCB is shorted ???
was he lying or speaking truth ??
It seems you already got the answers you were looking for - consider ordering a replacement switch as mumaster20 suggested.
There's no need for you to post links to this thread elsewhere.
Yo can just clean the power button contacts & the contacts on the PCB and it should work, after that try the button before assembling the phone

Yes , I wont
So I think that the button is not able to make contact with these two contacts on the PCB is that the mechanism ??
Or is the button (the two golden pins) always in contact and create a short only when button is pressed ??.
It would be really helpful if someone can answer that .
Thanks will be given .

When you press the power button it shorts the two contacts together so it must be clean, my guess is that you will find some salt from the water on the button contact which should be very easy to clean
thanks

Ok thanks a lot !!
did what was said
Today I opened my Nexus 4
Did what was said . Cleaned all contacts and especially the power button !!
assembled everything back !!
Everything else is working now except the power button
One thing I observed is that even when I touched the two golden pins of power button using tweezers the screen turns on !!
So I think my power button is defective !!
So can anybody provide me a link where I can buy a power button .
or maybe anyone whose device is not working and may want to sell his power button .
Problem Solved

I do the same and button is OK again.
All the problem of this button is when the glue from the tape go to contacts and make bad contact. When you removes a half of tape, clean the internal contacts with alcohol and pass WD40 with cotton swab, the button is OK again. After this, put the tape on their place again. Dont need to put more tape, only use their original tape.

So the power button on my phone is busted.
Long story short, someone dropped it and the button broke.
Anyways, i was using the camera button to turn before, but then now it dont work.
It still turns on when i get a call or have my headset plugged in to it.
Do any of you guys know how to change a button to become a power button. maybe make the camera become a power button.
Thanks for your help.
use "do not lock buttons" in Keylock menu and than install KeyLock app to manage autolocking after suspend (to prevent auto poweron) and set it to "lock after wake up").
You can also use Battery Status to do that
I have seen an issue where the power button was knocked out of place, to resolve this, I took the back off the unit and pushed the button back into place, this resolved the problem, it is also possible the solder points have been broken... really easy to solder back on.
cheers
Steve
same problem here

WELL then, it was just the main motherboard that had displaced itself, making the ON-button misaligned with the button on the board... so, i pressed the motherboard in place, and voila! the phone is good as new
i almost died of nerves, but it turned out all right after all... *phew*
Hey, i just replace my digitizer for my t-mobile hd2 and successful got it back together and thought that everything was work, but i could not get the volume button in. I got it in after putting the chassis on but the volume button still doesn't work. So if anybody could give me some input on this that would be very helpful.
Do you feel the button take action when you press it? If it does, then the contact is made with the button, the problem might be something else.
a guy from HTC repair said its better to change whole screen instead of replacing digitizer.
As mentioned, can you feel the button depressing when you add pressure to the rocker? Pull the case back off and press the button manually to see if it works when powered on. If it works then, realign the flex cable and retry. If it still doesn't work, then you most likely damaged the flex cable and need to replace it.

In addition to said above check housing screws, they must be tightened because if they are missing plastic volume keyboard will misalign with flex cable volume keys and it will be impossible to press them.

At first i forgot to put back the last 4 screws so the housing was not on tight enough but i now i did that and its still not working. So now im going to try look over the flex cables again and hope that will works.

It can be found on eBay for about 43-44 bucks. Good luck!
usualy i am good with physical problems like this but i am now forced to make my own thread because i have no idea why my device wont power on.
after opening my blackstone/touch hd to tighten my screws, my power button has stopped working.
(fyi, a screw came loose a while ago near my sim card after dropping my devive so i thought id tighten all my screws while i had my screwdrivers out fixing my cousins phone)
however, without having the plastic power button attatched to the device, i am able to press the actual button with my stylus and make contact with the main button on the motherboard, the device will now power on.
(eliminating that the actual button to power on is broken)
but, when i attatch the plastic button and press it to power on the device, it doesnt make contact with the actual button inside on the motherboard.
(not making contact with the button on the motherboard)
i have examined the plastic button, all is intact and i am assembling it to the device correctly.
i have examined the actual power button on the motherboard and that is working perfect.
what the hell is going on?
thanks
Rn
ps, i need my power button
cba putting my stylus in and taking it out whenever my backlight goes off
* if you want a picture of my plastic button, i will dissasemble my device and take a picture.
Pictures ?
I have successfully replaced the screen on the HTC HD2 Leo, but after assembling the phone the volume button is not working. I am not sure if there can be something missing as I cannot feel the 'click' when it's pushed. (not sure if it was there before though)
As far as I remember the volume button consist of two parts: the printed circuit and the plastic button. Or is there maybe something that needs to be connected that I have missed?
Thanks for any hints

dismantle it again, it can be the plastic button its self, it acts like a spring under its own tension, when I re built mine the first time the lower button had stopped worked well, and it was simple because I hadn't put it back right, it was, and it looked right, but it wasn't quite right
I would a agree with dazza9075. Sometimes when putting the phone back together it may look right but sometimes its not. If i remember correctly there is a little spot it fits right into but you need to make sure it goes in in just the right way,
both on the top and the bottom. There is a complete how to guide to replace the lcd screen on the HD2. If i find it I will post the link. It may clear up just how you need to place the vol button back in place. Worse case you can always find a
cheap volume button for only a few dollars on ebay to see if maybe you broke this one when trying to replace the screen.
Hi, I did not manage to fix the button, but managed to get by without it.Till now. I was looking in google for a solution and found my own tread from ages ago...
Now, I would need to put the button together again. I looked into it and I guess I am missing a piece that the plastic button is supposed to be pushing. Before I order something, can anyone please confirm and possibly post a picture of what the button it should look like under the plastic part. Also if you know what the part I need is called, please let know. Please see below how my button "circuit" looks like.
Many thanks for any help
This is what you should have bellow the button

Thanks for your response. I could not find the buttons separately and have therefore ordered the button ribbon for the 5 hw keys for under $3, which hopefully will be possible to dissemble and transfer. I would rather not buy the whole flex cable, where's the button is attached to, as this is quite expensive $20+.
I let you know if I was lucky. If you know where I can buy only the small pieces I am missing, please let me know.
A pic of what I ordered is attached fyi
i can confirm that you can use buttons from that tape, I've had the same situation, just pick up the circle button and add it to volume tape.
Mine was damaged during assembly, you have to be very carefoul
You can actually do lcd & digi removal & refit without need to remove flex ribbon completely thus keep the volume button & cables running to mainboard all in place and those small button caps are safe still wrapped in original tape & it all goes back together factory style ...
Good afternoon, see if you can help me.
I have received a Psmart that got wet and with some rusty part, I have managed after cleaning the rust and changing the screen (15e) that everything works except the power button.
The button works well but looking at the motherboard it seemed to me that something was missing and looking for photos I have located that the rust ate the resistance of the power button, and therefore it does not turn on (to turn on, I disconnect the battery and then I connect it to the power supply)
Could someone tell me the value of that resistance?
I attach an image of the area of the plate and a diagram of the resistances, I am missing the one indicated with the arrow that I put as 1.
Thanks!!
