My Lenovo Notebook is charging but its not switching on, what's the probably problem?

Help please!

Motherboard issues. Even without the battery installed it should still power up when it is plugged in. Because it is a laptop they will probably replace the motherboard as the connection between the power and turning on is not working. It could either the button to turn on or something else. Whatever it is it is not booting.

If it was able to power up and your drive was dead you'd get the "blue screen of death".
