RE: erratic touchpad when AC charger is plugged
Mine was erratic as soon as it was booted up to LINUX (version didn't make a difference). At first I thought it was a software bug, but it turned out to be the non-DELL power adapter, brand name, "CBD", I had my e6400 plugged into. If the power adapter was disconnected the cursor worked perfectly. I had a second "CBD" and tried it with the same result. Threw both away. With a DELL power adapter everything works just fine.
