[ Samsung N310 netbook; stock specs; always kept cool and looked after] My Samsung N310 netbook died last night under strange circumstances - never had a fault quite like this before: - Generally browsing the web - Screen suddenly goes off (not just the backlight, LCD panel also). could this be a key point? - PC still running fine and responding to keyboard + external input (remotely connected to uTorrent GUI to see if it would respond). - forced a shutdown by holding power button - now won't power on Power button now has no effect. I have tried all the tricks that I know (leaving battery out overnight and unplugged, bad ground, remove RAM, those sorta things). Refuses to power on with either no battery in, or only the battery and no mains. I am competent enough to attempt a repair - but only if I know what the cause is. What do you reckon is to blame here? I'm assuming it must be some power hardware fault that is causing the POST to fail (thus doesn't turn on for damage protection). Guess the most likely is the power regulator area (dead capacitors?) as surely any other hardware fault would still allow booting to BIOS at least...? Or the hint may be in the LCD failing. Thanks for any input.
