Hi all
I have a HP Pavilion 15-ab291sa.
I'm hoping someone out there has come across this issue before.
The laptop turns on when the AC adapter is plugged in and the fan immediately starts on full blast.
A message appears on post that a system fan has malfunctioned and the computer will turn off in 15 seconds to avoid damage, hit enter to continue setup.
So with the fan clearly on I had no qualms hitting enter and seeing what happened. nothing the keyboard is not working.
plugged in an external keyboard and the laptop boots up loads windows fine (the fan is still on full this whole time btw)
Popped the back off and reset the BIOS. no joy
Updated the BIOS no joy.
When i disconnect the integrated keyboard the issue goes away, fan spins normally and the laptop starts up and works fine.
So the issue is if i plug in the integrated keyboard not only does the keyboard not work but if you plug in the power adapter it, starts the laptop and causes the system to display a fan error, plus the fan is full on all the time.
FYI the power button on this laptop is NOT on the keyboard.
If you've ever heard of or experienced this issue i'd like to know if it's worth replacing the keyboard or this is more likely a board issue?
(the keyboard is part of the palm rest so it's not the cheapest component to buy)
