CMOS battery possible getting on abit?
laptop clock slowing
Recenty put more RAM into a laptop (from 500MB up to 2GB) and the date/time clock seems to have slowed, loosing a few minutes a day.
Doesn't seem to be any other effects. Any reason for this? Any way to correct (other than reverting to the original RAM
Thanks in advance, John

The only time I have seen this is when the motherboard was faulty. There is a 'real time clock module' that is just like your digital watch. As long as it is supplied with power from the battery the crystal vibrates and the clock counts. If your clock is running slowly then I doubt it is to do with the install of new memory............but I am willing to be wrong.
Put the original memory back in and see what happens.
That would be my guess too.CMOS battery possible getting on abit?
Thanks all.

A what?CMOS battery possible getting on abit?
Sounds expensive. Don't remember the clock slowing before the RAM was changed but that doesn't mean to say it wasn't.The only time I have seen this is when the motherboard was faulty.

This is on the list to do, just wanted info of any possible causes.Put the original memory back in and see what happens.
Given the age of it, this is a definite possibility.Try winding it.

there is a battery on the motherboard(dont no the size of the top of my head,a big watch battery like in your uwatec/suunto dive computer)Thanks all.
A what?
it controls the power for basic setings in bios and the clock,the occasionally need replaced
It will be a CR2032 battery.there is a battery on the motherboard(dont no the size of the top of my head,

Thanks,
would this also be termed an RTC battery?
Laptop service manual shows one with a lead and plug connector attached.

no need to answer as have just been searching for replaement and have discovered what RTC means.

Whilst waiting for the battery, you could configure the laptop to use an internet time source service to keep it in sync:
net time /setsntp:timesource
net stop w32time
net start w32time
w32tm /resync

I think that is what I said on the first page but I didn't use a TLAno need to answer as have just been searching for replaement and have discovered what RTC means.

Doubt it is the battery....does your quartz watch slow down when it needs a battery change? Mine don't they just die. Your RTC works the same.
On a desktop the CR2032 battery tends to clip into a battery holder. On a laptop/netbook, because of restricted space, they often have a lead and plug into a connector so the battery can be secreted in a hole somewhere else.

Because you have speeded up your computer it has slowed time down.

Of course ! I knew that there would be a rational and logical explanation. None of that motherboard & battery bollox.

Might not actually be far from the truth. Since it happened when you installed new memory, I'm wondering whether it is a slight mismatch in clock / bus speeds between the new memory and motherboards causing the system timing to be slightly out..

If so, there might be some BIOS changes you need to do to adjust for this mismatch. Or just rely on the net time command to keep your clock updated correctly
