Need help! Computer stays on!!!!!

[Dawn true]

Ok so something bad happened. Computer shut down except when you hit the power button it lights up but nothing happens. Even after unplugging it and removing battery, you plug it back in and same thing. So I can't do a single thing! I have no clue what to do

Thank you for any help!!

The light stays on the power switch, as long as your pressing on it, it doesn't just stay on...

Had 2 spare QSs that showed the same behaviour, pressing that small button on the mobo (NVRAM-reset ??) solved it for one of them, the other stayed a dodo....
