Question Need assistance w/ DIY A500 Repair (Power Button) *ACER FIXED IT!*

I'll have to take pictures later when I get home so you all can have a better understanding of my problem.

My power button stopped working two days ago (no click or reaction when pressed). I never filled out any of my warranty things & I have no idea what my serial number is. So any who, I opened up my tablet and carefully disconnected the battery and all necessary connectors so that I could see what was causing the button issue. Turns out, the power button switch had disconnected from the circuit board.

I went and bought a soldering iron but after a few attempts I realized that I was going to have to go a different route. The chip itself has five connections to the board and these connections are under the chip itself. What is the best way for me to reconnect this chip to the board? I'm thinking of purchasing some thermal adhesive and seeing if that does the trick since without this part I'm looking at a large paperweight. Any suggestions?

I'd like to help, but without seeing how it actually is I'm having trouble with that. And I don't feel comfortable opening my tablet without a good reason.

Could you perhaps supply a few pictures?

Added two pictures, sorry if they're not clear enough. The whole thing is pretty much trash unless I'm able to repair this or get it to someone that can. People should be aware when they push their power button super hard - doesn't have anything keeping the chip firming in place.

Thermal adhesive might not be the best idea. It's primarily meant for conducting heat, and thus it seems most thermal adhesives are somewhat electrically conductive. In other words you could possibly create a short and fry something.

In theory I agree that using something glue-like substance would be the easiest way to go, but you need to find something that is not electrically conductive in the least and when it dries/cools down that it hard. If it becomes a soft blob you'll find you're still having issues with the switch staying down and connected.

I'd personally still go with soldering it down and then applying something to ensure it stays there, but you'd need a very tiny soldering iron -- like e.g. one used by clocksmiths -- and steady hands. And preferably some experience with soldering something so small.

Your eleven digit serial # is inside the cover of the sd card door, a one year warranty is on all acer tablet, if they cannot fix it they would have given you a new one from the place of purches mine would be staples, i call acer usa all the time, i call today and ask if the 500 will get ICS the answer was when google release the code they will..

I would suggest soldering it, its the only thing that will hold the switch in place long term. They do make a conductive adhesive for electronic circuit board repair, but it is more for repairing boards, not really for attaching components. It wouldn't be too hard to solder it back on, just get some solder wick and remove all the old solder first, then re-attach the switch with new solder. If you don't feel comfortable doing it, take it to your local TV/Electronic repair shop. Since its already out and all they would have to do is re-solder the switch, it probably wouldn't cost too much to do. Although what the other poster said about returning it to Acer to have them repair it is probably the smartest answer. If it does have a year warranty, then that's what I'd do.

I believe once you've opened up your tablet, your Acer warranty is VOID. Sorry.

Any insight as far as how they would know? I called acer last night and was given all the info as far as how to send it back. Hopefully if they notice I did some tinkering, they'll just fix it anyway and bill me or something. I definitely regret panicking about this situation & opening it up when that was totally unnecessary.

There should be a tamper-evident seal underneath the MicroSD/SIM compartment door. It rips when you disassemble the tablet. It is a little black square sticker that says something like "Warranty void if broken" (I dunno exactly, I already removed mine completely). It's hard to miss.
