My touch pad went wild all of a sudden too on my HP. Windows opening wildly... (it is happening now as I type too.) An internet window just popped on and off.
My work disappearing on me out of the blue.
I turned down my sensitivity.
I took it to computer repair 2x. No luck. So bought a new HP lap top just now.
This one is all jumpy. 8 windows opening at once. Then disappearing.
I tried to return the HP after 20 days, they said it had to be within 14 days.
So, I called HP today. 2 hours with them, and the Indian guy says it will be $14.00 on your Visa for a level 2 tech support. (I said no way. Bye)
So, I cancelled my extended warranty. And now I am stuck with a computer that screens just open and close at will.
I would have to also use an external mouse, but I am disabled and use in a remote bed, so that won't work.
I sent HP feedback today as they sent me an email on How Was Your Experience with TECH Support.
