Use this guide to replace the power button board in your Lenovo ThinkPad T460.

The power button board contains the button that turns on the computer when pressed. Diagnosing a faulty power button may be tricky since some of the symptoms are similar to a faulty battery or AC adapter. If you are pressing the power button but your laptop is not turning on, take a look at this Lenovo ThinkPad troubleshooting manual before attempting a power button board replacement.

If you need to perform a replacement, make sure to disable the internal battery, power down your device, and disconnect from any external power sources before you begin.
