Clock in Windows 7 going too slow. Can't figure it out... :/

[ZaO]

The taskbar clock in Windows 7 seems to be ticking too slow or something. It really starts to fall behind after a while. But it seems to sometimes sync up. Probably because it's connecting to the Windows time server.

I did a lot of searching about this yesterday. The thing that kept coming up, was having a knackered Bios/Cmos battery. I don't think this applies to me though. The Bios clock is bang on time, everytime I check it! I tried disabling the option to sync with the Windows time server. But it still happens. I've never had this happen to me as far as I can remember. So I'm not very familiar with this problem.

Any ideas? I'm gonna be very late for a lot of appointments if I don't get this sorted haha

Thanks!

Try enabling use of the HPET instead of windows 7 default.

Open a cmd prompt as admin. Type:

bcdedit /set useplatformclock true

It's not normally needed on win 7 (but is on win 8), but it may improve things for win 7 as well.

What possibly makes you think that? A battery is a battery!

The symptoms you're seeing are actually classic of a failing battery. When the machine is off, the battery has a poor voltage, which is causing the clock to have issues. When you power it on, it'll sync with the timeserver and 'snap' back to being correct. It's most likely to be wrong when you first boot between booting and its next server time fetch.

They're a couple of quid off Ebay, delivered. It's one of the easiest things to test / fix if it's that.

Battery would affect BIOS time too. TSC timing issues only affect Windows, which seems to be what he's seeing.

I did notice that said it wasn't for my OS when I was on that MS page. I thought I'd look into it anyway though. Maybe I shouldn't!
