i think i have to change laptops soon...just this morning i got a real grand scare coz my laptop won't boot!!! i had the same problem in 08
HP replaced the system board coz it was defective...looks like the same problem is gonna happen again...better back up all my files now...
I think u should avoid HP...at least in my country....it's the one that we sould'nt buy
i dont know where to start!!! coz it might not open again anytime!!!
