Yesterday afternoon I acquired an Acer Aspire 7520 laptop from my friend. It's been broken for a few months now. At first I was just going to pillage the parts from it, but I've decided to attempt to fix it since it's better than my current laptop. <a href="http://www.techsupportforum.com/hardware-support/ram-power-supply-support/343165-acer-aspire-7520-repeats-going-off.html" target="_blank">This</a> is the problem it's having. I'm guessing from that thread that the problem is with the CMOS battery. I have the keyboard removed and I'm guessing the CMOS is the thing in the below picture with the blue ring around it, underneath the ribbon cord. I tried applying pressure to it as outlined in that forum and no luck with getting it to boot. What to do? This is my first time dealing with this sort of thing, so any help is appreciated.
