I would say it was a hardware problem. Depending on how easy it is to remove the top plate of the computer you can see if the ribbon cable to the touchpad or keyboard is securely attached. 

 

In addition to the above boot a live linux disk and see if you have a touchpad. If not then I would say it's hardware requiring a new touchpad/topplate of the computer.

 

Make sure the touchpad is enabled either from the function key or it could be a small button just above the touchpad with a small light indicating if the touchpad is on or off.

This system simply won't load a linux, The owner said it's no problem for him to use an external mouse so I'm not going to open it. I am not seeing any options to enable touchpad.

You may need to enable Legacy Boot and disable SecureBoot in order for the linux disk to boot. On a HP tap F9 at boot and it will give you a boot menu with the option to boot Legacy.

 

What is the model number of the HP15? Looks like there is not on/off switch on the latest HP notebooks.

Oh sorry, I should have mentioned I did disable legacy and tried from both the internal and an external drive and with 3 linux disks. The linux "runs" but doesn't open up the interface. Model is 15-1272wm

You actually want to enable Legacy Boot. It could also be called CSM boot. I'm not sure why linux failed to boot though. Was linux on a disk or USB flash drive?
