My aunt gave me her 7 year old HP Pavilion G7 (Windows 8) to fix it because it didn't seem to load or something.

I looked and the battery is dead. However, the laptop is very slow and when doing nothing the CPU is at a good 92%.

The fan turns up immediately and goes to maximum.

That's why I plan to install an SSD and clean the fan.
I tried to open the laptop with a bit of force and loosening the clips with the screwdriver is not ideal. Now there are not so beautiful tracks.
