Hello,
From a week I have a problem that made the laptop unusable. When I'm typing something, the input on the screen stop every 1.5 seconds and stay frozen for about 0.5-1 seconds. Meanwhile I continue with the typing and after its unfreeze, its mess up the input. I try everything. Update drivers, uninstall drivers/devices, reinstall, I try with clean boot, even I reinstall the windows with newer and older version.
The laptop Is ok with i7 and 8 GB of ram. I went to your technicians for my country, they check everything but there are no hardware problems. Also they try another keyboard and after this - another parts. Still the same. The input is laggy. I was thinking that it was from the win 10 updates, I didn't know witch one was, so I remove all of them - still the same. That's why I install another 2 windows 10 and one win 7 images. Still the same problem. After this I try with Ubuntu and Linux, its work perfect. I install again windows 10 and again the problem. When I connect an external usb keyboard its ok.
Also if i press the left arrow key for a long time the input is 4, for the right one is 6. But if i press them for a second its ok. PLEASE HELP!
