HP Laptop wont turn off

[benzee5]

I have an HP laptop that wont turn off.
When power down, the fan never stops running and the HP logo stays lit up.

I can unplug power and batter, leave for a week. Then plug battery in and immediately the fan starts running and the HP logo is lit up.

I tried going thru the cmos settings to no avail.

Did you make sure your laptop's BIOS is up to date? Might want to share your laptop's SKU with us. On another note, with the battery removed, press and hold down the power button for 30 seconds(while unplugged from the wall as well) and see if replacing the battery and powering up after 15 mins changes your experience.

BIOS is updated, no change. Unit was shut down, power cord and battery disconnected for few hours. Plug battery in, HP logo flashes then lights up, fan is running.
Oh, I also held power button for 30 seconds without any power plugged in.
