Laptop makes a lot of noise when you turn in on
The laptop makes a lot of noise when it’s on. The noise was getting worse over time.
1. The cooling module is clogged with dust.
2. The cooling fan failure.
3. Hard drive failure.
Possible troubleshooting steps and repair solution:
First of all, take a look into the cooling module. It’ possible that the cooling an is clogged with dust and the laptop makes a lot of noise because of that. Clean the cooling fan and heat sink and test the laptop again.
If the laptop makes noise only when the cooling fan spins, most likely you have a faulty fan. Try replacing the cooling fan. The hard drive also can be a source of loud noise. Remove the hard drive and boot your laptop from a live Linux CD (you can use Knoppix). Test the laptop for a while. If the noise is gone when the hard drive is removed, most likely you have a faulty hard drive. If that’s the case, back up all personal data from the hard drive as soon as possible because it may fail any time.
