Try the following steps to resolve the issue:

Verify the power status indicator.
The power status indicator is illuminated whenever the computer is on and is not in standby or hibernation mode.
The power light should also be on if the PC has power.
Check all power connections, and remove any power strips and surge protectors to connect the AC adapter directly to the AC power outlet.
Inspect the AC adapter.
Check for any physical damage to the adapter, cables, and plugs, and ensure the power cable is firmly attached to the adapter brick and the system.
Verify the AC power source is working by attaching another device to the outlet.
Remove the ThinkPad system from any docking stations or port replicators.
Remove devices and then test for system power with minimal devices attached.
1. Disconnect the AC adapter.
2. Remove the battery (if the battery is removable, check the manual).
3. Remove devices that can be removed, such as external keyboards or mice.
4. Wait for 30 seconds before reconnecting the devices and power sources.
5. Reattach the AC adapter to test the system with minimal devices attached first.
6. Reattach each device that was removed in the previous steps, one at a time.
