If I set critical battery to 0%, does it mean that even if I have Hibernate on critical battery, the laptop will simply ignore it (since at 0% it is does not even have the power required to do a hibernate anymore)?

Or is it true that no matter how low I've set that number for critical battery (even 0%), the laptop will still try to run the mode I've set on critical battery (currently set to Hibernate that is), and thus will attempt to Hibernate (save my stuff) before actually power-dead?

Note that I'm aware at times due to sufficiently low power, the computer can "try" to Hibernate but will fail halfway (leaving things in a GG state), I'm simply wondering if I have critical battery set to 0% it will even "try" to Hibernate).

  • What?! Setting critical battery level on 0%?! Please... please don't try this out - this is MADNESS! – user1136553 Mar 20 '20 at 15:58
  • Is this Windows 7? – user1136553 Aug 14 '20 at 3:35

Yes. In this case, zero doesn't mean it is dead. Zero means whatever the battery tell the OS. I've done this before and usually Windows will hibernate your computer before you get to the critical level.

I don't see the point of setting to zero.

    well if i set to zero i can be able to squeeze maybe 3 more minutes of usage before my battery dies out – Pacerier Aug 12 '11 at 8:16

    You realize that that absolutely wrecks havoc on your batteries total cycle lifetime. . . – surfasb Aug 12 '11 at 8:31

    but how, or why is it so? i'm really nt aware of it. – Pacerier Aug 12 '11 at 9:00

    There are like 1000 battery life cycle articles out there. All I know is people who know far more calculus than is humanly possible have said so. So I listen to them. . . – surfasb Aug 12 '11 at 9:30

    what had calculus gotta do with this?! – Pacerier Aug 12 '11 at 11:21

In short, yes this will work

However it is a little pointless, you'll only be getting a few minutes more of battery. The only way I can see this being possible is if you wanted to destroy your battery and have just enough time to shutdown your computer. It would be much more reasonable to set it to 5%, that way you aren't killing your battery (by killing I mean chemically destroying it). The point of setting a critical battery level in your operating systems interface is to make sure that your computer turns off by itself, not because it is out of juice. If you are that desperate for battery, you should consider taking a charger with you in your backpack, laptops don't typically take that long to charge.
