How to secure laptop after a 'hacking'?

[Two-Six]

Doug,
Perhaps just try booting into it';s BIOS or booting from some kind of try-it-out linux distro like Ubuntu or Mint.  You need to make a DVD with it on first or make a bootable USB data stick.  Boot from it and see if the mouse/keys/touchscreen work ok. 

They probably will and its probably just Windows 10 being rubbish. 

Like ched says, try to get the proper drivers from HP for windows 10 for your laptop, uninstall the old ones and install the new ones.  Also try another USB keyboard/mouse if you can.

You can test out these Linux versions without installing it or making any changes to your hard drive, just be careful.

It does exactly the same when Keyboard/Touch pad is removed from the Screen  and I have tried the Bios and HP diag';s etc to no Avail it is the wierdest thing I have seen in 30 years that i have been playing with PC';s

My Wife Laptop has developed an interesting mind of it';s own?
It is one of these relatively cheap HP Convertible W10 machines where you can pull the screen away from the Keyboard part and use as a tablet so wonder if it may be an issue with the touch screen membrane or something.

I';d check it without the keyboard connected first, look for electrical noise nearby too, is it right close to a speaker or motor of some kind? Is the screen damp?
Use it in tablet mode on a wooden table away from everything and see if it is the same.

Yep first thing I tried so it';s either got some malware in it (Which isn';t showing up) or it has a faulty Touch membrane causing it?

I have seen the effect before when pluging in a serial GPS Dongle and windows seeing it as a mouse it is the same sort of thing.

What is strange is that if you can get logged into the machine leave it 10-15 mins or so it will settle down and start to behave normally which also makes me suspect the screen is the issue.

To Be perfectly honest I don';t think it is worth bothering with it is very low spec and can';t do much with it other than internet browsing and FB.
