Windows 7: System Time not kept correctly after having manually changed BIOS time

Dear all,



I spilt some water on my laptop a few days ago but fortunately it's completely dried out and working perfectly.... apart from this minor (but important) issue. I would appreciate your help.

Problem: the system time does not stay correct. Even after manually updating the BIOS time and also even after manually syncing it with the various servers available under the time options.

Fix: set the internet time sync interval to every minute rather than its default setting? How do I do this?

Much appreciated.

P.S. This couldn't be a CMOS battery issue surely because even when the system is on and plugged in the system time still deviates from correct. (I assume the CMOS battery is only used when the system is powered off.) If I need it replaced, how does that sit with my Dell hardware warranty?

For right now, lets just try to update your time. To do this, click on the clock in the bottom right. Then, click on change date and time settings. In the window that comes up, go to the top and click on the tab titled Internet Time. Then, click on change settings. Click on update now in the windows that pops up.

Yes thanks; I've tried this and although initially working for a couple of hours, after a while I notice the time is wrong once again. (I.e. it's not moving on fast enough to keep accurate time). Has been the case for the past few days.

Thanks for your suggestion.

I'm having the same problem but it has suddenly popped up. Nothing spilled on the keyboard or anything.

Its as if DST gets reversed for no apparent reason.

Is your maching an HP?

Does your bios clock stay accurate or is it getting off also?

I'm thinking maybe it isn't all the way dry. I would take it apart myself, but that can get very involved. I dont know what Dell would do warranty wise...

BIOS is off too.

I've updated it numerous times. It corrects the system time but only for an hour or less. It soon deviates from the correct time.

Question: does the system time still run off the CMOS battery even when the system is powered on? If so, a simple (I hope) replacement may fix things?

Have you checked for Bios updates from Dell's support page: http://support.dell.com/

Yes, the time in the BIOS clock remains accurate. It is only within Windows 7 Ultimate that the problem happens.

Yes. I think it does. Either that or it only runs when your system is powered down.
