hi, I've been given a used m15 r4, I haven't been able to use it yet as it will not power on. I have checked all connections inside and all looks good. I have tested the charger in another laptop and it works. I'm not sure where to start with working out what is wrong with the laptop?
Any help will be appreciated.

Hello, it's very possible that the board is dead but it's hard to know for sure without testing it myself.

The power adapter (charger) should have a blue halo light at the end. Does this light go out when it is plugged into the laptop? If it does then you have a short on the motherboard (usually related to the GPU). This means you will have to replace the board.
