How do I change the low battery notification?

You can choose when to be notified that your battery is low.

Windows warns you when your battery charge reaches low, reserve, and critical levels. When the charge gets low, the battery icon in the notification area indicates a low-battery level. When your battery charge reaches the reserve level, Windows notifies you that you're running on reserve power. At that point, you need to save your work, and then find an alternate power source or stop using the computer. When your battery is almost out of power, the battery icon indicates a critical-battery level, and then your laptop goes into hibernation.

If you don't have enough time to act after seeing the low and reserve battery notifications, you can increase the percentage of battery remaining for these settings. This can be especially useful for older batteries, which might not have as much storage capacity.

To change low, reserve, and critical power levels

  1. Open Power Options by clicking the Start button Picture of the Start button, clicking Control Panel, clicking System and Security, and then clicking Power Options.

  2. On the Select a power plan page, next to the plan you want to change, click Change plan settings.

  3. On the Change settings for the plan page, click Change advanced power settings.

  4. On the Advanced settings tab, expand Battery, expand Low battery level, Reserve battery level, and Critical battery level. Change the percentage of battery remaining that you want for each level, and then click OK.


    • You can't set the critical battery level below the minimum level set by your computer manufacturer.

    • You can also change the actions (Sleep, Hibernate, Shut Down, or Do nothing) associated with the low and critical battery levels.
