I have a HP DV7, with an AMD Turion X2 ZM-85, purchased about 1.5 years ago.
Initially the laptop screen turned black. Only the screen – the machine was running. I could hear the fan spinning. Then I had to forcefully switch it off and keep it like that for about 15-20 minutes before I could restart it. I know I have to wait that long because I already tried turning it on before.
I took it to tech support and they said it was overheating. So I got the fan cleaned and added thermal grease too; it was all going well for a while. Then, I ran into the same issue again.
I also installed Coretemp and could observe that as soon as the temperature reached 60-64 °C, the laptop would shut down.
The issue went on and on... chill mats.. chill-pads with fans, but nothing really came in handy. Now the worst part is: The laptop doesn't switch on at all. When I try switching it on, it is runs for about five seconds and then shuts down again. (the fan spins)
I'm tired of this problem and honestly don't have the money right now for a new one. I'm reluctant to purchase any hardware without knowing what exactly the issue is here.
How can I restore my laptop back to the normal condition?
