Back up your files people.
DO IT NOW.
At the very least have it done by the time you go to bed tomorrow.
Old computers die.
New computers die.
'Reliable' computers die.
Just thinking/talking about backing up ain't going to be good enough when smoke starts streaming out the back of your laptop.
I haven't had it confirmed that I've lost everything. But the smoke that came out isn't making me feel to hopeful.
I've been without my beloved laptop for one week, stealing a few minutes on my sisters computer at the moment.
Hopefully I'll be back soon.
At least it was still covered by warranty.
