An alternating current adapter transfers power from a wall outlet or power strip to the hp smart adapter. The AC adapter also charges the battery — which allows the computer to run for a short time without receiving power from an outlet — installed in the laptop. If the computer fails to turn on, the AC adapter or the battery could be defective. To troubleshoot power problems on the HP ac adapter, test the power cord and the battery separately.
Instructions：
1、Hold down the power button to turn off the HP battery charger. Remove the power adapter from the power jack.
2、Close the lid and turn the computer over. Push the release tab on the right to unlock the battery from its compartment.
3、Push the release tab on the left to eject the battery. Pull the battery from its compartment.
