First thing to try:

Remove your battery and charger, hold the power button for 10-15 seconds. Plug the laptop into mains ONLY leaving the battery out. Try powering it up.

If the laptop powers up ok, shut-down and re-insert your battery. You should find your laptop will continue to work fine for the foreseeable future, this kind of issue is a common occurrence on laptops.

If not I would then try re-seating your RAM/Memory, if that doesn't work and you have more than one stick remove one at a time to see if either one is causing the problem. If you have only one stick find a replacement to test your laptop with.

If you are still finding the same issues with the laptop I would then proceed to reseat all components of laptop, including the CPU.

If the issues continue I would then remove all non-essential components one by one, each time attempting to power the laptop. At worst you will eventually end up with just the mainboard, CPU, RAM and an external monitor plugged into the mainboard, that still doesn't function correctly. I would then conclude your mainboard needs replacing.
