System clock loses time - have tried everything

By "that issue about time zones" I assume you are asking if I've confirmed that I'm in the correct time zone, which I have. Supposing the only place you do that is in the Date & Time Settings. And it continuously lags, slower and slower, it doesn't just stay one consistent time. I've had it tell me it was the year 1600, which obviously messes with my programs.

Have you checked that the NTP service is running on your O/S?

Because it appears like you have a system clock issue, have you tried setting up the clock to repeatedly sync with one of the internet time clocks? If not, here's how:

And just a thought... A number of Vista users were able to fix the problem by disabling/uninstalling their antivirus program.. Many using Norton were having such issues. If disabling it fixes the problem, then you might want to try a different program.

Hope this helps.

Then the news is grim. To fix it we have to replace the motherboard.

See if you can enter the BIOS and set your clock to that year. My guess is that you cannot and I've not seen a board that would set back or forward more than a very few decades and certainly not 400+ years. If you can't set it to a date you've seen, you most likely have an OS or software issue. Many years ago, I remember a few shareware programs that would monkey with the clock and usually would just stop it. If this issue is easy to repeat, you might try just booting to the BIOS screen and letting it sit there over night this way to see if the clock keeps good time. If it works ok this way but not when running your OS, you've got another reason than hardware for this.

...and only replaced the CMOS battery a few months ago (December).

If I boot to BIOS and go to the date/time settings, the clock does not tick at all. It just sits on whatever time it was when the PC was shut down / restarted (assuming it can remember that).

If I run the Dell Diagnostics, it suspiciously hangs at 20%, being 'IRQ 8 realtime clock interrupt'

I've had Windows tell me it was the year 9999 earlier this week.

I suspect it's a case of 'time for a new motherboard', though I'm hoping someone out there might have some clever idea (given the age of the laptop, replacing a mobo isn't really a worthwhile option).

Curiously, a Google search for this returned a number of reports of the same problem, all in the early months of 2011.

While it might be possible to fix a motherboard, today no one does that. Hope it's under warranty.

Hi all, searching for help with a similar issue. My 2.5 yr old XPS1530 started losing time about 2 weeks ago. Again when the power shuts down the time freezes. Initially it was giving me an error message when I tried to update via the Internet Clocks ntp. etc.
I've now re-installed windows,drivers, updates etc and the time is still freezing when power is off or computer is shut down.
Cleared DSKCHK OK, then ran Dagnostics from F12 and it sticks on 20% with "IRQ8 Realtime Clock Interrupt".

If I can get this sorted I'll feel comfortable creating a Clean Back-up for future restores.. which I have no doubt are not far away ?!?

Any advice, guidance or assistance is much appreciated.

PS. First HDD was replaced after 5 months when it gave up, battery lasted all of 18 monthhs and the second one is now also starting to lose power and not charge fully. My 2nd and quite possibly last investment with this company.

From turning on NTP, replacing the battery on the motherboard, setting the clock to changing the motherboard, this has been fixed so many times I've lost count.
