Quick question
Hello All,
I'm wondering what is causing a computer to lose the correct time. It is not all the time, but it has happened at least twice in the last couple of week. Could it be the CMOS battery losing power? The computer is about 4-5 years old. It is an HP KT373AA-aba with an Intel E2180 dual core processor. Don't have the MB specs. It is running Vista. Has 3 Gb Ram. Thanks for any help.

That would be my first guess. Are your BIOS settings also going back the factory default settings? If so, that is probably it.

Thanks David, I haven't checked the Bios settings, because most of them were at the default setting anyway. This is a very basic system of a friend, and she doesn't do much with it other than surf and email.

Usually the cmos battery. Good place to start anyway.

Ok, after putting in a new battery, the computer is still changing time on a rather erratic schedule. What else could be causing this to happen?

Have you checked your time zone settings (Pacific, Mountain, Central, Easter, etc) to make sure that didn't get changed somehow? Also might check the Daylight Savings Time setting to make sure it's right as well. If it's not this, I'm at a loss as to what else could cause it.

All of the settings you asked about are properly set.
The time changes occur normally at a boot-up. Normally about a twelve hour shift. |

Though I've never seen it happen, I could envision a stuck bit in the real-time clock. When it's read at bootup, whether the time jumps would be determined by the state of the bit if it weren't stuck. You'd have to keep track of when it changed and by how much to figure out if this is what's going on, and the fix would be a new motherboard...
A workaround would be to set the machine to check the time over the Internet more frequently. |
