Sounds like a dodgy power issue within the laptop if it powers up ok with external assistance.
Try a different power lead inside the laptop if its a possibility.

Reset the BIOS to default settings.
Usually F2 on start up. Follow instructions on how to reset it using the options given on the screen. Usually F9 - F10

When you tried it in the external power supply, how long did you leave it running for?
It could be a duff fan, try it again in other PSU and see if it cuts out after a while

The fact it's spinning when you fire it up for a couple of second as the board is running through its checks, suggests the fan is ok. Although some fans have a chip inside them that can go wrong. You need to see when the machine is hot if there's power getting to the fan from the board. You can do that with a multimeter. If when hot there is power getting to the fan but the fan is dead, then it's obviously the fan. If there's no power its either your BIOS or motherboard imo.
I'd also try taking the battery out of the motherboard with the lead and battery unplugged and holding down the power button to drain any power left in the board for 30 second. Then try again.

I'd be tempted to also try earlier versions of the BIOS failing all above

Also try boot f12 and run diag on the fan if there's an option.

Yes you can downgrade a BIOS.

thnx
if it was fkd it wouldt work on ext pwr supply would it or would it
It may do yes.
It depends if the internal and external power supply are the same strength.
If the external one was slightly more powerful it could fire it up.
A tester would let you find out
