Besides the minor Error 137* issue
many are waiting for a solution power config on this new PC (August 2013) has never worked right under W/8.1, and while I had Fast Boot disabled, as well as hybrid sleep, and hibernate enabled, going into the latter results in
Windows failed to resume from hibernate with error status 0xC0000411.
It also wakes from sleep prematurely even though the power on is disabled under Network adapter, and timers as well.
Everything looks fine in Device Manager, and it has latest drivers I know of, and W/8.1 updates.
*The system firmware has changed the processor's memory type range registers (MTRRs) across a sleep state transition (S4). This can result in reduced resume performance.
