Hi friend ,
please check follow this.

The first time I changed the tochscreen digitiser on my Orbit I had this. After much messing about I tried putting the cases back together without the power button in the case, and when I pressed the power button inside with my stylus it worked fine. The reason I tried this was because months before my power button was messing-about, working intermittently.
I tried fitting the button back in and re-assembling the cases but still the phone wouldn't come on. In the end I shaved about 1mm off the silicone press-pad on the back of the power button and it worked 1st time.

Power Button Failure

For those who experience the power button failure here's an easy fix that works for me.
Determine if it a power button issue
Pull battery wait 5 seconds
Put battery back if it automatically boots up then the button is stuck on
Disassemble your phone to the motherboard
Get some WD40 yes I said it LOL
Spray a little on a table surface
Use qtips and dab a little well alot on the power button
Now keep pressing it on and off about 20 times to get the oil running
Assemble and enjoy

Your instructions are not very clear. And I tried turning my partially disassembled phone on without anything touching the internal power button and the problem persisted. Does that sound like I need to get it completely replaced?

If doing this and your problem still persist then yes completely replace it some of us are lucky that this alone was enoughvto fix it.

[Q] Power button ribbon issue

Hi, I'm wondering if any electronics expert can help me with this. I dropped my htc m8 and the screen shattered. I decided to replace the screen my self using YouTube videos as a guide. I replaced the screen, connected everything, and powered it on and it worked flawlessly.
When I tried to fit the phone back into the silver case, I did not fit properly so I removed it. I tried powering the phone but it didn't power up. After a bit of wiggling with the top power ribbon, I managed to power it up. But the button is not stable, ie sometimes it works and sometimes it does not. Is it an issue of a bent cable? If there is a solution that does not involve buying a new board I will appreciate it.

[Q] Phone wont boot after replacing charger port.

So here's how it went:
I opened the phone, replaced the port (the small boardlike thing)
assembled my phone to try it.
The phone started
Then I put all the screws and sim card But I didnt get signal no matter how long I waited
So I dissassembled it again. I was a bit harsh and broke the "Power" button. (the rubber thing that makes it bounce fell off, and an small metallic circle that probably completes the circuit fell off as well.
(Google "galaxy note 2 charger port" for a picture, cant post external links @[email protected])
Checked everything was plugged properly and tried to start it with the tip of a paper clip to complete the circuit where the power button should be (that small round thing)
Nothing happened so I googled a method to start it without using the powerbutton:
youtube: Gre9qaJyCZw
Basically its to plug the charger, wait for the battery logo to show, unplug, take out the battery and put it back in quickly.
So I assembled the phone again to try that and when I connect it to charge it the screen flashes for half a second (no words no nothing, it just brightens up for a bit) And then the red led that means its charging turns on after a couple of seconds.
After doing the trick, the led turns on blue....then the phone vibrates a bit(seems its starting up, but with no sound or nothing in the screen)
And then the "menu" soft key blinks a couple of times and then back to nothing
So I just have no idea what to do @[email protected] I dont mind replacing the button but I would rather not spend on it if there's something else wrong with the phone...any ideas?
And I just bought this to replace another phone that broke ;_;
EDIT::::::
I replaced the charger port for the old one and tried the starting trick. but to the same result: after doing the trick, the led turns on blue....then the phone vibrates a bit(seems its starting up, but with no sound or nothing in the screen)

you probably messed up the mainboard or some connections.
Try to power it on with microusb board disconnected.
Make sure every single connection to the main board is connected properly

Any suggestion as to how I can start the phone with the power button broken and without the microusb board?
I already checked all the connections that you can see when replacing the microusb board (the back side of the motherboard) Is there connections worth checking in the front?
Do those symptoms sound familiar for any specific problems? (Like non working screen or motherboard)
- Charging takes a couple of seconds to turn on the red led when connected but shows nothing on the screen.
- Trying to start it with taking out the battery trick makes the led turn blue, then the phone vibrates a bit, then the menu soft key flashes a couple of times.
Update: I found 2 more symptoms
1° Kept restarting the phone with the battery trick, and a couple of times I could hear the music of the phone starting up, but it seems to be at random or due to some factor I have not spotted yet
2° If I connect it to the computer it detects the phone and lets me access the files. Kies detects it as well
If phone can be accessed through kies I think you have broken some connection between logic board.
Power button and volume + - buttons should have the same round metal part, which will work after swapping.
I think you should give up, maybe there is still hope for repair.

Thats the weird thing. if you take a look at that phone's board, the only things that are within "breakable" range when you open it with a plastic tool are:
power button
charger port
earphones port
volume buttons
And they all seem fine except for the power button. there's no other flexors or anything even remotely close to where the tool was used. (and where I got a bit rough)

Nexus 7 Gen 2 won't turn on

Okay, here's the story. My Nexus 7 Gen 2 went into the water for half an instant. However, when I tried to turn it off immediately, it wouldn't turn off. I put it in a container of rice for a couple of days and eventually, it turned off - the battery died, I'm sure. Anyway, now, when I plug in the charger, I get the battery charging symbol, however, it will still not turn on. I've tried some of the button combos mentioned (hold power for 30 seconds, hold power and volume up for 3-5 seconds, hold power and volume down for 15 seconds, even hold power for 2 minutes), yet nothing seems to work. But as soon as I unplug it and plug it back in the charge symbol appears. Any suggestions?
Thanks!
Chris
Okay, read some more on here and got it into boot load mode. Pressing the up arrow puts the start arrow at the top of the screen pointing to the power button, the down arrow "restart bootloader", however, pressing the power button does nothing.

If you put the tab in the rice container without removing the back, you don't know if all the moisture that seeped in has been removed. You need to disassemble the thing, dry each and every component inside with a blow dryer ( both sides of the electronic boards) to make sure of that. Thereafter, you can try again. Because even if you succeed in flashing the OS anew, you'll never know when the residual moisture will interfere or affect the components again.

I didn't use a blowdryer, but it sat out on a table with the back off for about 24 hours and I do live in southern Colorado in the high desert, so humidity isn't a huge factor. I may give that a try today, though. Thanks.

I'm afraid some corrosion has set in already and it may not be reliable anymore.
Next time, you should immediately disassemble it and disconnect the battery, then use a hairdrier to remove the moisture ASAP.

So, given that it will open into the reboot screen and the volumen buttons seem to work but the power button itself doesn't work, could it be possible to replace the power and volume buttons and get it to restart? Just wondering if I can manage to salvage this thing.

Yes, try to replace or test with multimeter the control buttons assembly first but if it does not help then remove the motherboard and its shields, and check it for any visible signs of corrosion. Scratching off a conductive corrosion layer may fix it.

Did a screen replacement and now power and volup doesn't work.

Hey all, I've just done a screen replacement. It went okay apart from the phone bootlooping on the first try. This was due to the ribbon connector at the bottom of the phone (for the motherboard to display) somehow, as it was loose. I've fastened it properly since.
Now everything seems to work okay, except for the fact that the power button and the volume up button both do not work. I have to boot through fastboot currently. Does anyone know what could cause this during a repair? The buttons all click like they should and I can't see any obstructions inside the device.
