@drewdevaultI have an extra X220. Battery is shot... Haha, but that's an easy fix.
@herag 220 or X220? Only the former has a serial port
@drewdevaultX220... Dang, and here I thought I could be helpful. I know from experience that USB to serial are always really buggy. I have a stack of like 20 laptops, mostly Dell... I'll sort through them and see if any of these have a serial port.
