I found a neat trick to fixing the problem with resuming from standby on the M200 when using updated video drivers.
– Windows 7 x86 build 7100
– Forceware 98.16
– Dual Displays enabled (see other posts)
After resuming from standby press Fn + F5, the switch display function, twice. This will cause your computer to attempt to switch to the secondary display and then back again to your primary display which will reinitialize your screen.
I haven’t done enough testing on other setups to say that this will work for everyone, I’d imagine that so long as you have the Dual Display trick enabled you should be able to do this.
