AC adapter not working?

When the AC adapter (charger) fails to work, it will neither charge the laptop battery nor provide power to operate the laptop without battery power. Power issues on a laptop are compounded because a laptop has two power sources: AC adapter (charger) & battery. When AC power is not available, power is provided by the laptop battery.

If you're having issues with your AC adapter not charging your laptop, please try to follow these steps to solve the problem.

Inspect the AC adapter, cables and adapter (DC) port on the laptop for damages

1. Unplug the AC adapter from the wall outlet.
2. Unplug the AC adapter from the laptop.
3. Check the AC adapter and cables (including the power cable) for signs of physical damage or overheating.
4. Check if the pin inside the plug or adapter port is bent, broken or damaged.

Verify the wall outlet is working

1. Unplug the AC adapter from the wall outlet.
2. Connect another device to the wall outlet to verify if the wall outlet is working correctly.

Drain remaining power 

1. Unplug the AC adapter from the wall outlet.
2. Disconnect any external peripherals connected to the laptop.
3. Press and hold the Power button for 30 seconds to drain a residual power from the laptop.
