too fast
102 Chapter 8 Troubleshooting guide
Procedures
1. Verify that battery is recognized and charging.
2. Verify battery condition if battery cycle life is over specs (i.e., long life of 1000-cycle life
and 3-year warranty). Battery may have premature capacity loss within its cycle life or
warranty.
3. If issue remains, test with a verified working battery and verify battery status lights
and battery conditions.
4. If issue remains, replace system board.
5. Verify the new replacement.

Procedures
Possible causes
AC adapter and/or battery.
Troubleshooting steps
Verify AC adapter
Determine whether the computer needs the AC adapter to boot and operate.
Sometimes, intermittently bad AC adapter and loose connection between adapter and
computer results in inability to charge battery and causes short run time.
1. Inspect AC adapter to verify that it is working.
2. Test with AC adapter alone and with a verified working AC adapter.
Verify battery: Battery capacity can degrade over time, so check the warranty
coverage. Run a battery test to confirm if issue is hardware-related.
1. Review battery power plans in Control Panel > Power Options that may consume
more energy and discharge battery faster. Resetting default to Power Saver
option can conserve battery power.
2. Determine whether any graphics processing is running.
3. Verify battery maintenance and operations. Leaving the battery at a high level of
charge in a high-temperature environment for extended periods accelerates the
loss of capacity.
4. Test and calibrate battery using HP PC Hardware Diagnostics (UEFI).
5. Verify battery life cycle using HP Support Assistant tool.
If battery cycle life is over specs (long life battery of 1000-cycle life and 3-year
warranty), battery may have capacity loss beyond its lifecycle or warranty.
