Hello everyone.
I've got some ACPI problem with my notebook (BNB4312) - under the win 7x64, when it was working only with the battery, he was constantly freezing - no matter at game or in windows..
After installing windows 8.1 x64 this problem was solved, i haven't seen any problems so far...but
USB 3.0 device did not working! it just working in usb 2.0 mode, and didn't even display in the device manager as a device!
