Could be a bad power supply, failed hard drive....
Is it plugged in when you try to turn it on?
My HP Pavilion laptop is just turning itself off. I turn it on, and two or three seconds later (sometimes immediately), the screen just goes blank and it shuts off. As if I suddenly pulled the power from it.
Any idea on what could be causing this? And what can I try to fix it?
Problem started yesterday, it happened once, but it stayed turned on the entire time once I turned it on again So I didn't think much about it. But today, it barely goes into 2 seconds into the start-up phase. Also, the laptop is a bit under 3-years old.
