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.
