2. Verify thermal solution
Use Thermal Monitor tool (available only to authorized service providers and
technicians)(HP Thermal Monitor on page
and verify that thermal sensors are within limits after thermal condition is serviced.
User configuration
Change Power Options in Windows (for example, choosing Balanced mode instead of High
performance). High performance and extensive graphics might cause the fan run constantly
to release the heat.
BIOS currently omits fan presence detection to shorten boot time delay less than four
seconds. Therefore, the fan error is generated based on previous boot to operating system
that found system fan error.
Fan often is part of thermal solution, including heat sink, heat sink fin/muffler, and thermal
grease. Fan replacement requires reboot and fan function verification using HP PC Hardware
Diagnostics (UEFI) tool.
