Inspiron 3421 Touch Screen problem
I have Dell Inspiron 3421 with touch screen. It came with touch screen and windows 8 preinstalled.
It did worked well in initial 1 year but later on it was not working sometimes and then completely stopped.
I have upgraded to windows 10 hoping it will detect hardware and will work. But it didn't.
By reading various community blogs I have updated BIOS, chipset , display drivers too.
But still its showing "No pen and touch device" in computer properties.
Any other suggestion ?
