I bought a T410 to use as an Ubuntu laptop for robotics work. I can't find any info on what the buttons above the trackpad are for, and the online user manuals I've found can only be used in Windows, as part of the help system!
Could someone tell me what the upper buttons are for?
I really can't believe there's no PDF online for a user manual, but after some hours all I've found is a hardware service manual, which doesn't seem to have any clues. Trial and error tells me what the two lower buttons do, and the red joystick. A manual would be nice to help with BIOS fiddling, too. Sigh.
