Issues, possible causes, and fixes (continued)

Items

Procedures
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.

Note

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.
