My laptop died suddenly. It will power on, but then nothing. There are no POST beeps. What does this mean?
could be a lot of things.
If you had a desktop it would be easier to diagnose. The simple ways to start are by replacing parts with known good one. Swapping parts in a laptop is a major PIA.
Could be:
the power supply
the ram
the video device
the CPU
other
In a desktop, you would start by removing and reseting each of these items to make sure it wasn’t just that they had come loose and no longer had a good enough connection.
If you are asking this question, I doubt you want to disassemble your laptop.

Does anything at all happen? Does the screen light up a bit? Does a fan start whirring?
Try taking the battery out then plug it into the mains.
