HP/Compaq Business NoteBook 6715B Battery charging problem
Today I got HP/Compaq Business NoteBook 6715B Battery for repair with the battery charging problem. It is a new model and we do not have a lot of experience with these laptops. The customer complained that the laptop will not charge the battery when it is plugged into the AC outlet.
HP/Compaq Business NoteBook 6715B Battery 6 cells 4400mAh
The laptop failure symptoms:
The laptop will not turn on when I try to start it from the battery. When the laptop is turned off and plugged into the AC outlet the battery charge LED doesn’t light up. I know that the battery is not charged and the LED should light up when I plug the laptop into the AC outlet. The laptop starts fine when it is plugged. When I move the mouse over the HP Power Icon in the lower right corner, the balloon will pop up and there is a line in there: Battery Remaining: N/A.
The problem repair procedure:
You can easily fix the problem just by updating the BIOS. HP says that the BIOS version should be at least v1.30. So, go to HP/COMPAQ website and click on Downloads. Select your laptop model and find any downloads for the BIOS. In the BIOS change history you will see the description of changes.
After I updated the BIOS, The HP/Compaq Business NoteBook 6715B Battery charging problem disappeared.
