Touchpad is turned off on my hp elitebook 8560w

hp parts surfer, go there, tell country
and product number for PC
(I have this PC)
and what you see there is all you get.
its all there, read it.

https://partsurfer.hp.com/partsurfer?searchtext=8560w

first clue there is this

Heat sink with fan - For use in models with AMD FirePro M5950 and NVIDIA Quadro 1000M graphics cards

you can change any thing you want but the mobo only fits your model. its not a desktop that has ATX motherboards that I can swap endlessly.
I own 3 , 9540s and all have video card 3 or more choices
a rare thing in laptops, (one reason I own them)
most laptops made are soldered down BGA GPU. ok?
first off HP does not sell these cars, ever, so ebay is the best place, or google and find them 3x more expensive../
see this search , took me 1second.

Is there a little orange led on the upper left corner of the touchpad ? If yes double tap on it to enable the touchpad.

one of the buttons on or near your keyboard will enable/disable the touchpad. maybe you hit it accidentally ?

Try to remove your battery and hold the power button for about 45-60 seconds. Then put your battery back in, and try to reboot. This may not help, I'm just eliminating possibilities hoping your motherboard isn't at fault.

it overheat so put it on the cooling pads

What is the make and model?

probably a conflict in either the address or interupt for the device. Loo in device manager and see it if tells you there might be a conflict.

those cards only work in your country.
they must match. (commications laws, RF)
no country stated by you, earth is big place and we are WWW.
the manuals cover all that. you asked, it has its own place .

the book is free to read. see the 10MB large book here,
service. bingo

Hi,
You might have disabled the touchpad accidentally. If the touchpad is disabled it is indicated by a yellow LED on upper left corner of the touchpad and when the TouchPad is active, the light is off.
To turn the TouchPad on, quickly double-tap the TouchPad off indicator (the yellow LED).

Hope it helps!
