IMPORTANT: Because an SSD has no moving parts, it does not make loud or clicking noises. Depending on type and rotational speed, some hard drives make more noise than others. Not all noises are related to the fan or hard drive. Table 6-50 Issues, possible causes, and fixes Items Procedures Symptoms Possible causes ● Loud noise from hard drive BIOS, hard drive firmware, driver, faulty drive, power supply (AC adapter). ● Clicking noise from hard drive Troubleshooting steps ● Still boots to operating system and operates normally 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. Tips 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). See Routine maintenance for performance improvement on page 118). Mechanical Use this information to troubleshoot mechanical issues. Noise (sound) Use this information to troubleshoot abnormal noise issues. Table 6-51 Issues, possible causes, and fixes Items Procedures Symptoms Possible causes Computer emits abnormal noise Aside from basic components (power adapter, supply, fan, speaker, hard drive, optical drive, display panel, external devices), it is also common for electronic components to produce noise. Troubleshooting steps 1. Inspect external power source and change to verified working one. 110 Chapter 6 Troubleshooting guide
