    T100HA forgets time of day when powered off

    Hello,

    If I power down my T100HA and turn it on a few minutes later, I often find that the Windows time setting
    is behind by as much as a couple of hours. The "update time automatically" setting does not seem to help,
    unless I turn that setting off and on again, at which point the clock gets correctly set.

    Is this a known issue? Or does this sound like a hardware problem? If this were
    a desktop PC, I would naturally suspect the CMOs backup battery, but of course
    the T100 has no user-servicable parts...

    The BIOS is up-to-date, I believe: version 214.

    I just noticed that if I go into the BIOS setup screen, usually
    the time of day setting is counting seconds, but sometimes it is frozen.
    Does that seem like a smoking gun for a hardware problem?

    Thanks,
    Doug

    I'm facing the same problem. It's a few days old tablet. BIOS clock is not ticking.
    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.

    I've been seeing the same thing on my desktops & notebooks.
    Either a Windows 10 problem (firewall) and/or a time server problem.

    The web is full of complaints regarding BIOS clock, mostly(90%) related to Asus Mobo, Tabs, PC, etc.). I'm surprised that they never looked at such complaint seriously.
    I've already raised a request through VIP.ASUS.COM. I'm waiting for the reply.

    ASUS says that CMOS battery is dying, so I've to run to their Service Center.
    I'm returning the product. Don't want to create problems for future.

    When CMOS battery dies, time returns to some fixed value, as 1.1.2000, on every boot.
    While my tablet doesn't show this symptom. It shows the time when I shut it. So, I think they have some other problem.

    Better if ASUS says it in clear words here, instead of telling us to contact somewhere else.

    This was my first ASUS product. Disappointed.

    There may be a capacitor that the main battery keeps charged, but there is no replaceable CMOS battery.

    I thought so - but didn't want to say definitively...
