Hello!
A friend asked me to look at his laptop (I have 15+ experience in assembling computers and home made repairs - but mostly desktops). The laptop died during a night, it was ok in the evening and completely dead the next morning. It's 15 months old HP Pavilion. There was no power outage or thunderstorm that night.
Now the computer shows absolutely no symptoms of life. When I plug it in nothing is happening, nothing on the screen, no humming, no electronics or even a single led goes on. Nothing! I checked the power supplier, used a spare one, on battery - still the same, dead. Then I removed the battery, hdd, CD drive, both memory sticks and then plugged it in - still no progress.
I haven't gotten further/deeper to the inside yet (my friend is still considering going with HP service) so I'd like to ask you what other diagnostic test I could use. Any ideas? Looks like it may be a power related issue, but to confirm that I would have to remove the cover.
Could it be a dead LCD screen? But wouldn't all power functions (battery charging, etc) work normally then?
I'd appreciate all hints you might have.
Thanks, L.
