My Laptop is KO-ed!

Assalamualaikum

My laptop is KO-ed and I feel like 'patah kaki' & 'patah otak'!!!

Adoi..what am I to do. All my files are in there - all my coursework files. My office work is safe and sound in an external hardisk.

My laptop cannot be switched on at all! So I've asked my friend to send it to a service centre for repair. So I don't know when I'll get it back. :(

p/s: I'm updating from a computer in the office.
