Great work! This also solves the problem on my Laptop: dell Inspiron 1720 (Intel Core 2 Duo T7500, Nvidia GeForce 8600M GT)
I did the following: 1) reboot and enter BIOS setup by pressing <F2> 2) use menu: [+] Maintenance -> * Load Defaults After this I re-enabled virtualization support because I occasionally use virtualbox: 3) use menu: [+] POST Behavior -> * Virtualization Both virtual console (ctrl-alt-f1) and power down is working now. Don't know what caused the problem in the first place though.
