AC adapter, battery, or both.
Troubleshooting steps
Verify AC adapter
Determine whether the computer needs the AC adapter to boot and operate.
Sometimes an intermittently bad AC adapter and loose connection between
adapter and computer results in the inability to charge the battery and causes
short runtime.
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: Because battery capacity can degrade over time, check the
warranty coverage. Run a battery test to confirm whether 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 are processing.
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 past its life expectancy (past the 1000-cycle life and
3-year warranty), the battery might need to be replaced.
6. Compare discharge time with a verified working battery (remove AC adapter)
using Hardware Diagnostics (UEFI)>Hard Drive Tests>Extensive Test>Loop
until error.
To conserve battery power, turn off Wireless On-Off button and other peripherals
and USB devices, applications, processes (in Task Manager) when not in use; also,
reduce screen brightness.
Follow HP instructions about how to maintain battery and increase
battery life. Also reference http://support.hp.com/us-en/document/c01297640?
