Touch screen stop working

you can try a hard reset by remove the battery and all power waiting for a half hour to make sure the capacitors are fully drained and then restarting this might reset the touch calibration. it also may be that you have a damaged or loose ZIF connection in the phone that needs repair or te touch screen portion itself needs replacement.

On a note to the bottom half of the screen not working, just bring it in to an Apple store and they will give you a brand new one. Thats what happened to me the other day, no questions no problems. You don't need to download anything, just bring it in and they swap your sim card into a brand new one. But if you messed with it and they dont accept it then too bad for you.
Thanks

there is one option that you have tak back-up your data then run recovery disk that is only solution becoz touch screen and finger print software is realy delicate things dont try to paly with if don't have to downlod drivers from the HP site

I recommend you backup your favorites.

Then attempt a hard reset.

Finally, replace the firmware and system software using webupdate.
Replacing the system software will most likely correct the malfunctioning keying of letters.

I hope that helps.

Your screen is broken. It needs to be replaced.

my workaround is to charge with a different power source, or stop charging. i think it's the power source. for me, the touchscreen goes crazy when i'm charging via usb with this old computer, but it's fine when i stop charging. it's probably an unclean power source messing with the capacitance sensor.

i think this is solved by another expert.

I have the same problem. But i had solved it. I use a lighter to burn on my viewty's touch screen, and it is working properly again within 30 secs. And ofcourse, do not burn the touch screen without a screen protector. Hope this solution would help.

can you use the arrow keys? if so do that or u can take the battery out and let it reset.

I had the same problem on the weekend...I think it may have something to do with the unit getting HOT, they say not turn the screen off whenever you can, cause that is what generates alot of heat
