R61 sometimes crashes on wake (Win 7 x64)

[glossywhite]

Hi there! I hope you are all having a fabulous day!


I have an R61 8930-A41, and I have Windows 7 x64 running on it, with all Lenovo drivers and add-on software, and from time to time, when I wake from sleep on "Maximum battery life" profile, the whole display fragments, and Windows 7 locks up completely, needing a long press on the power button & then a reboot.

Is this a known issue? Common?

Many thanks

Matt
