hi, i was disassembling the galaxy note 2 to replace the charging port and it was successful.
but unfortunately the small switch that powers up the phone fell and i can't find it.
is there a way to power up the phone? like touch it with some kind of metal or something..
NB: the cable of the power is all fine, it's just the button that stimulates it, fell off.
Thanks for help...
solved
seems no one had a reply. Well i managed to turn it on by touching it with copper wires. that is a temporary solution.
But luckily i found the missing switch

I just got this old phone from my friend after he upgraded. It's a solid phone but I'm having 2 issues.
1. The power button doesn't have the nice clicking feel to it. I opened the phone up and discovered the power button was one that I have not seen before. Is this button soldered onto the board? I would like to replace it myself, I have tried looking up power button fixes but was not able to find any results with this particular button type. It's usually the ribbon cable type deal with the flat disk contact kinda deal. Any idea where I can find some instructions and the buttons themselves?
2. I have a problem with the phone not powering down. After shutting the phone down the phone boots right back up or the screen shows the charging animation. Also the screen never goes into sleep mode it only goes into the dim mode. I looked up this problem and it seems to be a common one, a problem with the micro usb slot. I ordered the whole usb slot and the board its attached to. My question for this one is how difficult is the install?

I just replaced the screen one of my i777's. I followed this great guide my LE55ONS on YouTube. It was for I i9100, but they are almost the same phone. Along the way in the video he explains how to replace everything in the phone, including the microUSB board and flex cable, which if i remember was a pretty easy fix. As for the power button, i would try maybe putting a little piece of paper or cardboard or foam or something inside the phone right next to the button, that might make it more ferm when pushed.
Hope this helped.
Here's the link to the video :

Thanks for the reply, yes I saw the video too, it was helpful but that dang power button is so mushy it feels horrible. A little update though I was able to fix the micro usb port by cleaning it with a brush then bending the pins towards the screen, it appears that over time the row of pins gets pushed too far down and shorts the assembly. Power problems fixed but not the power button. Only place I can find that even has the power button repair service is mobiletechvideos

You might want to check the forums for your device, as the hardware between the I777 and the T898 are very different.

So when I was replacing the screen and the frame on my phone I realized the power button had a flex cable, one gentle movement and now it broke. I was able to order a new one but it's been 3 weeks since I had the phone taken apart and I don't remember how the flex cable attaches to the frame so that the button can actually touch it? If somebody could pop off their case and take a picture and/or undo their power button and describe how it goes back together that would be great!

In my experience, the power flex cable is soldered to the motherboard usually. You may have either buy a soldering iron and do the most precise work you've ever done in your life or contact a phone store. Sorry if this wasn't helpful.
The power button on a samsung note 2 that I inherited fails to work. The phone was left outside and rained on so when I first got it the screen did not work and I thought it was going to be trash however after drying it out and properly cleaning it the device screen works now and it will turn on when plugged in. I have one of the dongles that forces the phone into recovery but the power button just plain does not work. I don't know what to do but I would like to be able to use this phone.
I've dismantled a few of these phones and once I ruined a power button while sliding the the tool past it to pop the case apart. The power button is part of another assembly but can be replaced. Any version of the phone (Sprint/ATT/etc) will use the same subassembly for the power button. If that is the problem, you can swap it out.
Otherwise, you may have corrosion issues. I have brought older "dumb" phones back by spraying the circuit boards w/electrowash cleaner, scrubbing w/a toothbrush, and blowing off with an air compressor. Be sure to remove all ribbon connectors and scrub both sides of the connector. Also: DON'T JUST SPRAY THE PHONE WITH THE BACK OFF! the electrowash will stay visible the display, so do this in a controlled manner.
Hello. I read your posts about xperia z2. Unfortunately nothing is working. I don't know too much about the phone because is not mine. It's possible to have taken some water inside. At the moment no matter what I do, only the red led turn on when I plug it to wall charger or usb pc. It is not responding to any buttons or hard reset button under the sim slot. Most of the post are about flashing. But how can I flash if the button are not working? When I open it the battery had 3v. I charged it to 4,2 v but still not working. I also tried with the battery cable unplugged. Do you think there is still something I can try at this moment or it's batter to buy a new motherboard? Thank you in advance.
Have you tried to hard reset using power and volume up? Have you tried to flash via flash tool? If that doesn't work I'm afraid you have to buy a new motherboard.

Hold volume down while pluggin in the usb cable (connected to pc).
LED should turn Green, then you are in flashmode. If pc recognizes phone, try to flash a stock tft firmware.
Thank you for your answer. As I said, the phone is not responding to any button inputs. I tried power,volume -,+,red button under sim tray nothing is working. The only thing it does is the red led turning on when I plug it to usb. I read that a new battery could turn it on. I think the battery is good as long as it holds voltage.
At this moment I am trying the rubber band trick. If this doesn't work probably I need to change the mother board. I looked at the mother board and I can't see any damage (broken connectors, traces of fire...)

looks like just flash red led, no charging. When trying to turn on I can hear some clicking sound from motherboard, like small relay or something.
so my phone power button is sucks right now, and is very hard to press, i wonder if there is a way when my phone is dead, and by charging it will allow it to be turn on like an iphone! this helps alot, i dont care if i have to change anything as i am ready to take the risk if its possible!
The power button is easy to change and is very cheap. It's basically a flex cable and you cannot fix it. The copper switch is so thin that once you open it will break.
Here is a link where you can buy replacement flex
And you can find how to guide on youtube.
There was a trick to power on redmi note 2 with broken power button, maybe it works on RMN3 as well, but be careful with this method, you will have to reinsert the flex cable fast.

I see, is there anyway that I can just charge my phone to turn it on?
