Battery discharges too fast
Items Procedures
Symptoms
Battery has good status light but discharges too
fast
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 veried working AC adapter.
Verify battery: Battery capacity can degrade over time, so check the warranty
coverage. Run a battery test to conrm 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.
6. Compare discharge time with a veried working battery (remove AC adapter)
using Hardware Diagnostics (UEFI) > Hard Drive Tests > Extensive Test > Loop
until error.
Tips and tricks To conserve battery power, turn o Wireless On-O button and other
peripherals/USB devices, applications, processes (in Task Manager) when not in use;
also, reduce screen brightness.
