Hi! My laptop Lenovo 3000 c200. Mainboard 41w1389.
I'm having problem with my keyboard/USB. When I press any key on the keyboard, that instant all USB devices are disconnected. And soon after I unpress it, the system detects all USB devices like they were just plugged in. I say all USB devices, cause it doesn't matter USB mouse or USB drive, they all get disconnected.
otherwise, I used the wireless lan to connect .it get very slow speed.
how can i solve these problems?
P.S. can i replace my mainboard 41w1389 on mainboard 42w7673?
