system time doesn't keep up even after the CMOS battery replace?

Hi,

I have IBM T60 laptop. It's a few years old.
My system time doesn't keep up.
If I shut down and restarts a few days later, it shows the last date I used.

So I thouhgt it could be a CMOS battery so today I replaced it.
But the system time still doens't work.

I don't know what to look at now.
Any idea what could be the problem?
Just you know, my laptop battery's life is almost over.
It doesn't charge up and it only last 10 min or so before it shuts down.

have you looked at any settings in windows there could be a program running running eveyr 2 days to set the time back or something... other than that I would upgrade the bios... before trying anything..

i recommend you check with IBM itself, because for such issues you have two options only, either update the bios and make sure settings are correct or replace the CMOS as you did. As far as the main battery as power source is concerned it has no impact over CMOS battery because once CMOS battery is charged it works for quite longer.

cmos battery is a CR2032 coin  type in most cases - 3V and cannot be charged
either your bios is corrupted - resetting it by removing the battery + BIOS battery should reset it - or updating the bios as said should help
if this does not help it looks like a weird RTC problem

but look also at this - it could help :  http://support.microsoft.com/kb/307897

IBM Laptop CMOS batteries are usually specially packed with a cable (I don't know if that is also true for your model). In some situations I have seen that the contacts of the cable hadn't been properly crimped or soldered, so they didn't make proper contact. In another case I've seen the the connector where you attach the battery cable to the mainboard had cold soldering points, and so the power didn't get to the mainboard. In that situation resoldering the connector helped.

The battery packed in packed in yellow plastic and soldered.
I bought a battery and put in there. Let me take it out and make sure the contact it good.
After that I guess, I will order a new battery, actual part with the cable.

I had several laptops before and this is the first time I had to replace the cmos battery.
Thanks.

You could have the laptop sync with an ntp time server?  Any chance that you changed your firewall either physically or internally?  The port to sync with time servers is often udp 123.  Also did you test the voltage of the cmos battery, is it where it is supposed to be?
