Your HP Pavilion laptop can't survive for long without a working power jack. The DC power jack both provides power to the laptop's motherboard, and charges the laptop's battery pack. However, after repeatedly unplugging the power cord, your laptop's DC power jack is likely to wear out. This wear usually results in broken solder where the power jack connects with the motherboard. Fixing the power jack on your HP Pavilion dv6000 will require dismantling the computer and resoldering the power jack's motherboard connectors.
