The laptop turns on and everything works fine, except it makes some constant weird grinding or rattling noise.
Possible problem: In most cases this noise is coming from the cooling fan or hard drive. Take a closer look at the cooling fan.
If the fan doesn’t spin but the the laptop makes noise, probably it’s coming from the hard drive. Back up all personal data as soon as possible and replace the hard drive.
Also, you can remove the hard drive and stat the laptop. If the laptop still makes noise, most likely it’s bad fan.
