Clock loses time?

[BMM389EC]

I've noticed a few times now that the clock on my laptop loses time. I then have to reset it. Anyone have any ideas why this would be?

No idea why, but try either Atomic Clock (http://www.worldtimeserver.com/atomic-clock/) or checking if your PC has an NTP (Network Time Protocol) client.

NTP clients are available for Windows 95/98/Me/NT/2000/XP/ (http://www.timetools.co.uk/time-server/ntc-000-ntp-time%20server-client.htm) and also in other places.

Essentially they're bits of software which talk to time sources on the Internet and correct your local clock.

Also, just found this web site (http://geodsoft.com/howto/timesync/wininstall.htm) which has freeware, which I'm not sure the TimeTools site is.

AFAIK, every processor cycle sneaks a micro-milli second away from the clock cycle. It all adds up.

Not sure if this will apply to your laptop, but it does apply to desktop PC's.

Most motherboards have a watch type battery on board, which can be replaced. This is responsible for keeping time, and on some older motherboards, for keeping the BIOS settings up to date. I think this must apply to laptops because otherwise time would be lost if you removed its power pack.

Consult your laptop manual/manufacturer to see if this applies. It's good news if it does - only costs a couple of quid to sort out.

Is your laptop a recent one with Intel's Speedstep processor ??

My Toshiba 4010 (which my IT Dept kindly wiped XP off and stuck 98Se on :*) did the same thing. I could watch the clock miss about one in every 4 seconds. I turned off ALL the speedstep power saving in the setup I could find and haven't had the problem since.
