Update BIOS that may contain a table that assigns an appropriate adapter for a certain configuration. 2. Update the latest HP Hotkey Support software from Drivers website. 3. Verify sufficient power source (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 sub-system, a video balance mode may occur to further balance the power needs of the system. System processor functions always have priority over battery charging, so charging delays will occur first. Display Display anomalies The display panel is a field replaceable unit (FRU) and must be replaced by only authorized technicians. However, HP highly recommends that users and technicians observe specific symptom vs. generic symptoms and utilize the HP PC Hardware Diagnostics (UEFI) tool before any replacement.
