Procedures
Possible causes
BIOS, hard drive firmware, driver, faulty drive, power supply (AC adapter).
Troubleshooting steps
1. Update BIOS and hard drive firmware.
2. Examine AC adapter to be sure that it is not faulty or overloaded. Disconnect all
peripherals (USB storages, dock, and others.
3. Remove hard drive to isolate the noise.
4. Test the hard drive on a verified working computer if the noise continues. If the
hard drive makes the same noise or clicking sounds, the sounds are either normal
sounds for the hard drive or a fault with the hard drive.
5. Verify original hard drive connection and flex cable. Reseat hard drive and
connection.
6. Run HP PC Hardware Diagnostics (UEFI). If failed, record failure code and replace
hard drive replace.
7. If you find no error with HP PC Hardware Diagnostics (UEFI), perform disk
defragmentation. Some hard drives make a clicking noise when highly fragmented.
For optimal system performance, place your operating system and all of your most
commonly used applications and files on the fastest hard drive or solid-state drive and
on the fastest areas on the drive (primary partition of 200 GB max).
