Hi there,

We have a Acer Aspire 7720 laptop, it's getting on for four years now. I was just wondering if anyone here has a good idea to why it randomly cuts out?

I've cleaned it completely of dust, the fan seems to be blowing out nice cool air too. Done a ram check and they are fine. Swapped out the hard drive, changed from Windows Vista, to Windows 7 to Ubuntu but it still cuts out!

I tried seeing if it's the battery but even when running on AC power it still happens as well.

Absolutely clueless, anyone have any suggestions?

Thanks!
