Question about Sleep mode on Vista when a battery runs out...

[InlineFive]

Hey all,

I've recently been putting my machines to sleep instead of shutting down because it takes much less time to resume (esp with all of the memory SuperFetch would have to recache).

My problem is that sometimes I let my laptop go for a while on the battery and eventually it runs out while in sleep mode. I don't believe that while the computer is in sleep mode it can detect the low battery and hibernate, no?

From what I gather my only option to prevent data loss is to use Hybrid Sleep but with 2GB of memory that takes a while.

Any thoughts?

Thanks!

It is supposed to hibernate, but I think it is just based on a timer, not battery life. So the balanced plan has hibernate set to 1080 minutes by default. So I think the way it works is if you sleep your computer and it stays asleep for 1080 without losing the battery, it will hibernate.

There is also the critical battery life setting, which will make the machine hibernate if the battery gets critically. But like you said, I don't know if battery life is monitored during sleep.

That's good to know. Thanks stash!

I was wondering the same thing. I think you can sometimes hose your battery by letting it drain out completely, which is what I would assume would happen in the case of indefinite slumber. If it wakes up and hibernates after 1080 (minutes?) then that's probably a pretty decent solution.

Li-ion batteries have a circuit on board to cut power before they completely discharge. Those types of batteries will be damaged if they lose all power.
