what does powercfg /sleepstudy from an elevated command prompt give you? "Microsoft UART V2 Driver" at 100% in sleep?
I suspect this is something that'll get fixed in RTM. Remember 8.1 is a *preview*, it's not finished code...
WOW thanks. It is indeed the microsoft UART v2 driver that consume battery during sleep. I went to device manager, system devices, disable that sucker and guess what, it FIXED the problem. I don't care what is UART device but as long as my battery is not dropping, I'm happy.
