Thermal shutdown (hot)
Items Procedures
Symptoms
Similar to fan runs constantly issue (Fan runs
constantly on page 117)
● System shutdown
● Abnormal heat
● Continually running fan
● Decreased computer performance
Possible causes
BIOS not up to date, thermal condition (fan, air ow)
Troubleshooting steps
1. Update BIOS and drivers (4. Update BIOS and drivers on page 63) and reset
BIOS to default. BIOS may implement new fan characteristics and updates for
other component.
2. Perform a hard reset (8. Hard reset on page 70). Performing a hard reset can
reset recorded thermal values in memory.
3. Determine whether you are using a correct AC adapter.
4. Be sure to turn power o completely when putting a notebook in a travel bag.
Thermal-related issue
1. Verify thermal condition:
a. Check fan and connection. Reseat fan cable.
b. Be sure that no obstructions or dust are in heat sink fan, n, or vent.
c. Be sure that the notebook is not sitting on a hot surface that blocks vent
intakes.
d. Test fan using HP PC Hardware Diagnostics (UEFI) tool (6. HP Hardware
Diagnostics and Tools on page 64). Be sure that the fan is not producing
a loud noise and that fan blades spin correctly.
e. Test with a veried working fan.
f. Remove old thermal compound and pads, and replace properly with new
pads.
2. Verify thermal solution:
○ Use Thermal Monitor tool (available only to authorized service providers/
technicians) to run stress test (processor and GPU) and verify that
thermal sensors are within limits after thermal condition is serviced.
