X50V - flickering screen when connected via a USB cable?

as stated before, the reason for this is because it's not drawing enough power. for me, this is because on external power, my default brightness settings are to make it 100%. bring your brightness down to about 50% on external power source, and the flickering should go away.

this worked for me!

I have the same problem and simply leave the unit off when charging via usb, but have also noticed something else interesting. If my battery gets below 80 % then I can't activesync connect using usb, I have to let it charge up and then I can connect.
