Windows Vista December CTP (Build 5270)

So todays plan was to talk all about Windows Vista Build 5270. I managed to upgrade the BIOS of my new Toshiba M3 laptop yesterday and get the build up and running, complete with Aero Glass. Unfortunately, I was running on battery this morning and the machine went into standby which it wouldn't wake up from. 4 seconds on the power button was enough to cause BSOD on all subsequent reboots and last known good configuration is broken too :( I'll rebuild over christmas if I get a chance though.
