i have a x230 with a US 2 pin plug (20v, 65w). is it alright to use my previous x200 adaptor (local 3 pin, 20v, 65w) to power the x230??
i noticed that if i use the US 2 pin with a travel adaptor, i feel some static on the lid. the problem is gone if i turn off the power or use the old 3 pin plug.
so far using the old one seems to work, but when i connect the x230 to an external monitor, i get horizontal flickering, which i suspect to be a ground loop problem..... the flickering stops when i unplug the laptop from the socket. but last time no such problem with my x200 leh. weird.....
