[WS64]

Hi, is it normal that the NC's touchscreen behaves pretty strange when the device is charging (original cable/charger)?

When I press somewhere it mostly works, but sometimes the NC seems to think I clicked at a completely different location.
The virtual keyboard is nearly impossible to handle, when I click a letter not just one but up to 3 or 4 letters show up (usually just from the second keystroke on, the first one usually works normal, from the second on it shows different letters, not only the one I clicked).
Except that the NC works fine, and as soon as I unplug the cable the touchscreen works perfect again.
