Thinkpads Forum

I guess some of you must think it's not worth doing this, but I usually put my battery at 40-50% in the fridge, so my T60 is on AC almost all the time except I am on the road. I do this because I want to prolong the life span of the battery. I am kinda obsessed to this idea, anyway this is not the question I am asking.

So, I put the system into "standby" last night before went to bed thinking that I might use it again early this morning before heading out.

And it turned out that I didn't need to use the machine this morning, so I unplugged the AC adapter and came to school library. But when I pressed the power button after I settled in library, I was surprised to see the system returning from standby mode and everything I was working on is still there.

So anyone can explain to me why, what powers the system while the battery is in my fridge? Is it the little "button battery" on the motherboard doing this? I can hardly believe it.

Someone help me, thanks!

There are two possibilities:
1) The Ultrabay slot has a battery in it, or
2) You are mistaken in thinking that you placed the system in Standby mode or that the system came out of Standby mode.

The small battery inside the machine is only for preserving the CMOS setting for the BIOS.

Thanks for replying.

- No, I don't have a secondary battery, the only one is in fridge

2) You are mistaken in thinking that you placed the system in Standby mode or that the system came out of Standby mode.
- I might, but not likely, every program I was working on last night is there, and everything else is exactly the same as if it was returning from standby mode.

Your description does not differ from what you would see if the system were in Hibernate mode, which does NOT require power to maintain.

Possibly it was put in hibernation instead of standby, or it went into hibernation from standby for some reason.

This is precisely what happened.

Ok, thanks, I think two things might have happened

1. I might put the system to "hibernate" even I thought I did "standby"

2. some setting makes the system to "hibernate" after being "standby" for a while, this is probably the reason since I remember I heard a couple of beeping from the machine a while after I finished working last night.

Vista will go from standby to hibernate after about an hour of going into standby,which does not require power. Coming out of hibernate takes a little longer than resuming from standby.
