Notebook XP randomly going into Standby Mode while I am working.

After working fine for months, recently my Lenovo Thinkpad X60 notebook computer, running fully patched Windows XP, is randomly going into Standby Mode a few times a day. I know it is going into Standby Mode, because the Windows screen that says "Preparing for Standby Mode" that you would normally see when you intentionally choose Standby Mode appears. It happens when I am actively working away (e.g. using the mouse while busily working on something) so it isn't a matter of the machine being idle. It always comes right back by pressing the Power button, just as it would normally come back to life if you intentionally chose Standby Mode. I am plugged into the wall and the plugged-in indicator is visible in my system tray, so it is not a matter of it trying to conserve battery power. I have tried a full virus scan with AVG, and things appear to be clean.. same with spyware scan with ZoneAlarm.

All of the Bios, Power Manager and ACPI Power Management software was updated last month for that laptop based on here. http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-62938

I'd be making sure they are all up to date for a start personally unless they already are at the level from the download page.

Please note they could depend on each other so do the BIOS first, then then ACPI Power Management and then the Power Manager.

Crap I thought this was going to be an easy answer by going to the knowledge base, but
apparently this other persons issues have not been resolved either.. Me thinks I will not
be buying a Lenovo Laptop anytime soon.

Check out this link, try some of the suggestions.. I will post a followup question to see if
thwe original author had any luck with this. He has not posted back results as of yet.

We updated to all the latest drivers, and the problem now hasn't happened now for weeks. So perhaps indeed that takes care of it, even though we don't know what caused it.
Well I'm crossing my fingers and hoping they prove stable.

Hi. Well, amazing to me, it turned out in the end to be a faulty battery. When we have a certain battery in it happens (and other problems started emerging too, and becoming more frequent, which is what it made the problem-solution detectable). So thank you all for your suggestions and help.
I'd say tej071 gets the points then. They pointed to that first and foremost.
