My Thinkpad T420 turns to a sleeping mode after 1 minute of inactivity on any power plan. It ignores timer settings (sleep after 30 minutes in the Balanced mode and Never sleep in the High performance mode). I hoped that Lenovo Settings software would help resolve the problem but nothing changed after I installed it two days ago. Is there a solution to this?
P.S. I have most recent drivers and BIOS installed.

Just upgraded to Windows 8, installed all appropriate Lenovo Windows 8 drivers, system software, and BIOS, and I have the same problem. Power settings are ignored. It is particularly frustrating when trying to burn a CD/DVD, and the system sleeps and kills the burn. Anyone else encounter or fix this issue?
