So then it is probably the motherboard - the power circuitry on the board or its connection to the board components. No matter - still the motherboard.

It does take a charge and runs on battery <-- So the battery is OK, and it looks like the A/C Adapter is OK as well.

I suggest it is the power supply circuitry inside the machine and since the power button is not working properly, it is probably not just a loose power jack.

So unless the power circuit is separate (usually not) you are likely looking a motherboard here. Make sure the computer is worth that kind of repair.

If the Notebook is plugged into an AC outlet, try another power outlet or another power board to verify that the AC outlet is providing adequate power.

Disconnect the AC power, remove the battery pack, press and hold the Power button for 20-30 seconds. Re-insert the AC adapter and see if it will power on.

I had already checked the battery and power pack, both OK and with proper voltage and amps. I took off case, found no visual physical issues. checked power button, it physically works. None of these suggestions help so far.
