t490 touchpad erratic/problem when plugged to AC power or HDMI

2019-10-03, 14:47 PM

I have a problem with my touchpad. It starts work in a very strange way (slow and/or erratic movement) when I plug in the AC adaptor or HDMI. Nevertheless, I don't know whether this is related to a Software (or driver) problem or is the hardware (maybe not grounded properly).

Please help me because the laptop is just 5 days old!!
