My Dell Inspiron 9 cell laptop was fine till yesterday, it had slight overheating issues for which I was using a cooling pad. But since today, it KEEPS SHUTTING DOWN WITHIN 5-10 seconds of booting up. I COULDN'T EVEN COMPLETE THE HARDWARE DIAGNOSTICS TEST AS IT SHUT DOWN IN BETWEEN.
I have very important work stuff in my HDD and I don't want to lose it so I have stopped trying to figure out the problem as the laptop shuts down everytime, sometimes even before it had completely started.
Please advise what to do ASAP!
PS: My hunch is that the laptop fan isn't working as I couldn't feel any air coming out from the vent. I tried cleaning and replacing the battery but it didn't work.
