### Troubleshooting Adapter Issues

Inspect the adapter, cables and adapter port on the laptop for damages

The adapter cable and power cables may get frayed or cut, and wires may become exposed at either end of the cables. This may be due to the way the cable is wrapped around the adapter, or if the cable is subject to undue stress. If the damage is severe enough to expose wires, you should discontinue using the adapter. To check the adapter, cables, and adapter port on the laptop for any damages:

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

Verify the wall outlet is working correctly

-   Unplug the adapter from the wall outlet.
-   Connect another device on the wall outlet to verify if the wall outlet is working correctly.
-   Try a known-good wall outlet.
-   Plug the adapter directly to the wall outlet.  
    Bypass any power regulators like surge protectors, UPS (uninterruptible power supply), power splitters, etc.

Drain residual power

-   Unplug the adapter from the wall outlet.
-   Disconnect any external peripherals that are connected to the PC.
-   Remove the battery. Refer to the User Manual of the PC for instructions on how to remove the battery.  
    If the laptop PC has a non-removable battery, skip this step.
-   Press and hold the Power button for 30 seconds to drain a residual power from the PC.
-   Connect the battery.
-   Plug the adapter to the PC.
-   Turn on the PC.

Disconnect and reconnect the power cable and adapter

-   Unplug the adapter from the wall outlet.
-   Unplug the adapter from the PC.
-   Disconnect the power cable from the adapter.
-   Connect the power cable firmly to the adapter.

Update the BIOS

The BIOS is firmware that is embedded onto the System Board of your computer. Updating the BIOS to the latest version may help the PC recognize the adapter. Updating the BIOS to the latest version requires the laptop PC to be powered by the adapter and battery.
