Items Procedures
OS custom settings
1. Advise users to reset power options and close all applications that are not in use,
including applications in the background.
2. Test with a confirmed working operating system to isolate custom settings by users or
any conflicting applications that cause shutdown.
The following steps are for authorized providers or technicians.
Thermal-related issue
1. Verify thermal condition:
a. Test fan using HP PC Hardware Diagnostics (UEFI) tool ( 6. HP Hardware Diagnostics
and Tools on page 109 )
b. Check fan and connection. Reseat fan cable.
c. Be sure that no obstructions or dust are in heat sink fan, fin, or vent.
d. Test with a verified working fan.
e. Remove old thermal compound and pads and replace with new compound and
pads.
2. Verify thermal solution:
○
Use Thermal Monitor tool (available only to authorized service providers/
technicians) to perform stress test (processor and GPU) (
6. HP Hardware
Diagnostics and Tools on page 109 ), and verify that thermal sensors are within
limits after thermal condition is serviced.
Hardware-related issue
1. Check for any signs of loose connections, bent pins, stray wires, dust, nearly faulty parts
(bulging/leaking capacitor).
2. Verify that lights are solid.
3. If shutdown is reproducible, test essential hardware configuration:
a. If no issue with hardware configuration, reinstall one nonessential component at a
time to determine faulty hardware.
b. If issue persists, replace essential hardware with a confirmed working part, one at a
time. If the computer does not boot, replace system board.
Tips Intermittent issues are difficult to reproduce and troubleshoot. It is important to record details
about shutdown frequencies, system configuration (3D video application), and operating
conditions.
