The laptop turns on but the hard drive will not spin up. You cannot hear any normal working noise coming from the hard drive. The hard drive appears to be dead.
1. Hard drive failure.
2. Motherboard failure.
Possible troubleshooting steps and repair solution:
Most likely this problem is related to the hard drive failure and here’s what you can do to test the drive.
– Remove the hard drive from the laptop and connect it to an external USB enclosure ($15-20 in any local computer store).
– Connect this enclosure to any other working computer (laptop or desktop). If the hard drive still doesn’t spin, you have a bad hard drive.
If the hard drive works fine when connected to the external enclosure but doesn’t work when connected to the laptop, most likely you have a failed hard drive controller on the motherboard. If that’s the case, the whole motherboard had to be replaced.
In some laptops, the hard drive connects to the motherboard via a cable. In models like that, there is a chance that you have a failed cable. Try replacing the cable first.
