I have a Sony Vaio RB50. It has been left on for about 2 years straight, with occasional restarts and turning it off while on vacation. A couple days ago i turned it off and unplugged the power chord because my friend needed one for the night, and the next day when i plugged it back in and tried to turn it on, it just wont turn on. No beeps or anything, just no power at all. Anyone have any suggestions on how to fix this or what the problem is? Thanks.
