I've got the MB810, and am looking at some replacement parts (yay China! ) My question is a hardware question-what do I need? The power/lock screen button has lost it's spring, and doesn't like to react to being depressed. I have found the power button flex cable, but can't find any info as to what components it directly replaces, and if it would completely replace the switch, or just connect the buttons to the board. Any help would be appreciated!

Hello all,
I have a pretty quick question. I've been having problems with my power button lately. The power button makes the usual click sound as if it is retracting properly after being pressed, but it behaves as if I held the power button down. I took my phone apart and I noticed a black mark on the ribbon cable. I'm wondering if anyone will be willing to check their ribbon cable and see if this black mark is present.
This is becoming quite a nuisance because my phone will reboot when I press the power button after it has turned off. If it turns out that the ribbon cable is not defected, are there any other thoughts on what might be happening?

Thanks in advance for any help!
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.

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
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.
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?
