I have had a Dell XPS laptop die on me after I could not remember how to start the advance boot menu to start in safe mode. I thought it was F8 on start up, but this did not seem work. Then I thought it might be a combination of F8 & Ctrl, Alt, Fn. I tried all of these, mashing the keys so I would not miss the entry point on start up. Well this just killed the laptop, and now wont even start. Just before I was going to remove the CMOS battery, the power light was indicating that it was a processor failure (according to a google search), but now does not even do that. Is it possible I may have stumbled on a key combination that have could have increased the processor voltage (or something similar) and fried it. I know it must be VERY unlikely, but cannot understand that mashing a few keys could trash the dam thing. A new motherboard is so expensive, it is not worth replacing, better off buying a new laptop. Anyone else had a similar problem?
