How To Change Low, Reserve & Critical Battery Notifications In Windows 7

If you have been running Windows 7 on a notebook for a while now, you might have observed the low, reserve and critical battery notifications that popup in the notification area to warn you about the battery level.

With default settings, Windows warns you when the battery charge reaches low, reserve, and critical level. You get these notifications when battery charge reaches certain percentage so that you get enough time to save your work or to hibernate your notebook. For example, you see the low battery notification when the battery charge level decreases to 40%.

 

Here is how you can change low battery notifications (low, reserve & critical) in Windows 7:

1. Type Power Options in Start menu search field and then hit enter to open Power Options.

    That’s strange! I am able to set critical battery level to even 1% on my Dell studio laptop with Windows 7 Ultimate edition.

    Im having the same problem on my Asus Eee 1005ha on Win7 I cant set it lower than 4%(which is still about 30mins of battery!)

    I’v been told this “lowest value” is set by the manufacturer rather than Microsoft but is there any way of changing it?
