Clock not updating on bootup

[Tom H]

My system time is not updating when I boot up. I can do a time sync and the
clock seems to be OK after that but when I start up the next time, it's the
same problem.

Anybody have any ideas?

Duff motherboard battery?

Your clock will not update when booting, it will only update after
accessing the Internet. It may be that the battery is getting bad and
needs to be replaced. It is on the motherboard about the size of a
quarter. You can get a replacement at Radio Shack.

I thought of that but wouldn't that cause the system to lose all of it's
bios settings?

Not necessarily, clock can lose time and the CMOS settings still be ok,
or the default settings are used. If the battery goes away completely
then you get really ugly bootups.

Not really, if the battery is "just" starting to loose the power. CMOS
date/time "seems" to usually be the first thing to go.

Not necessarily. Your battery is presumably weak, not completely
dead. Your symptoms sound very much like a dying battery. Replace
it now, before it dies completely.

From XP Help & Support...

"Synchronizing your computer clock: If your computer is a member of a
domain, your computer clock is probably synchronized automatically by a
network time server. If your computer is not a member of a domain, you can
synchronize your computer clock with an Internet time server.

If synchronization is enabled, your computer clock is synchronized with an
Internet time server once a week. However, if you don't have a continuous
Internet connection through a cable modem or DSL modem, the automatic
synchronization might not always occur. In that case, you can force an
immediate synchronization by clicking the Update Now button on the Internet
Time tab in Date and Time in Control Panel. This tab is only available if
your computer is not a member of a domain."

Many newer machines use a common battery, the CR2032...available even at the
jewelry counter at WalMart.
It is the same battery as used in many automotive Keyless entry fobs as
well.

Duff motherboard battery?

Wouldn't that only have an effect of there was also no mains power?

I leave one of my PC plugged in, i know for a fact the battery is flat
because whenever I unplug it the time is reset - but if I switch it off
and leave it plugged in, it's fine.

If you unplug, there is no power to the pc. If you switch off and leave
plugged in, the motherboard is still powered.
