Hi classpad partners
I need some help. The classpad turns on but the touch screen isn't working.
First it start failing and i did a reset because the touch screen was having problems, but it was possible to use it. I can see the data on the screen but the touch screen is not working, but after the reset it worked ok again. From some time i didn't used the classpad and now the touch screen is not working again. I think its a system error that isnt detecting the screen or something like that, please help me with this problem, i need to use it urgently. I have installed OS 3.01.
How i can do a reset using the keyboard?
Thanks by your help.
