Procedures
Possible causes
Less powerful AC adapter, BIOS out of date.
Troubleshooting steps
1. Update BIOS, which may contain information that assigns an appropriate adapter
for the configuration.
2. Update the latest HP Hotkey Support software from Drivers website.
3. Be sure that the power source is sufficient (where adapter is connected).
4. Use appropriate AC adapter (often supplied with system) for optimum system
performance.
5. Test with a verified working AC adapter.
6. Test the adapter on a verified working computer.
7. Contact HP for configuration details.
HP Smart AC adapter warning message: informs you that as power demands increase,
the notebook may not perform at full capacity, which may result in longer battery-
charging time. In cases of extreme power demands, the system may also throttle back
the processor, or with systems that have a discrete video subsystem, a video balance
mode may occur to further balance the power needs of the system.
Because system processor functions always have priority over battery charging,
charging delays occur first.
Procedure
Possible cause
Real-time clock (RTC) battery might need replacement.
Troubleshooting steps
1. Reset the date and time in the operating system Control Panel.
2. Replace the RTC battery.
3. Verify that date and time are correct.
