I tried to stop windows time service, thinking it may be interferring. But, no, it is not.
Tried to download and flash the BIOS 214(ASUS Transformer Book T100HA | 2-in-1 PCs | ASUS Global). WinFlash says that it is too old to flash.
Restarted Time Service. No gain.
I hope it is a BIOS problem. May be clock crystal is bad.
Have you contacted ASUS? I'll trying to contact them.
Will update here.
