Windows 7 doesn't use x2apic mode. Windows 8 does and this same problem happened with this model: see http://forums.toshiba.com/t5/Windows-8-8-1/Resume-from-standby-issue-on-R830-PT321A-01K002/td-p/330110 Seems like your model was recently added to Toshiba's Windows 8 compatibility list: http://support.toshiba-tie.co.jp/windows8/list_au.htm Check for a more recent BIOS update that may fix this problem.
