Intermittent shutdown
Symptoms
●
Shutdown during startup
●
Shutdown during operation
Possible causes
It is often dicult to troubleshoot an intermittent issue. Possible causes include the
following:
Power-related issue: defective or insucient power sources, poor connection.
OS Custom Setting: Energy Saver (Power Management).
Thermal-related issue: thermal sensors reach limits.
Hardware related issue: voltage, out-of-range current; electrical short.
Troubleshooting steps
1. Update BIOS and drivers. (4. Update BIOS and drivers on page 68)
CAUTION: Do not attempt to update BIOS if the computer is shutting down at startup,
as running a BIOS update could corrupt the BIOS and require a system board
replacement if the system powers down during the procedure. The computer should be
stable enough to go through several start/restart cycles without issue before
attempting a BIOS update.
2. Perform hard reset (8. Hard reset on page 78)
3. Perform soft reset (9. Soft reset (Default Settings) on page 80)
Power related issue
1. Verify functionality of AC adapter alone. If no functionality, test with a veried working
adapter.
2. Verify battery alone. Verify that battery is not depleted. Test battery using HP PC
Hardware Diagnostics (UEFI) tool.
3. Verify connection of power button, power cable.
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 conrmed working operating system to isolate custom settings by users or
any conicting applications that cause shutdown.
