Common point of failure on a laptop is the power button

On any laptop you will have a power button. That power button sits on top of a mechanical switch which turns on your laptop. If you use your laptop a lot, the switch wears out. Some power buttons are easier than others to replace.

On this lenovo t460 laptop, you can configure it in the bios to switch on when you plug it in. This is also one of the easier ones to replace a power button on. Some laptops require taking the entire laptop apart.
