If you use a windows laptop or notebook, you might have noticed the notification pop up whenever the battery charge reaches critical level.
The notifications are usually displayed in 2 series. By default, the first one appears as pop up when the remaining battery charge is at 10%. At this point, it shows a low battery warning. A yellow exclamation mark is also displayed on top of the battery icon on the taskbar.
The second notification is displayed when the remaining battery charge reaches 5%. At this point, you will be warned that your PC will go to hibernation mode if you don’t connect the charger immediately. At this point, a red cross appears in the battery icon on taskbar.
Why change low battery warning percentage
Since last 7yrs, I own a Compaq v2000 series with an AMD processor. This model is power hungry and drains battery charge very quickly. Most of the time once the battery percentage reaches as low as 10%, it quickly moves to 5% leaving me no time to save files and close applications before the laptop shut downs. One way I tackle the problem is by setting the notification to 20%, so that I have enough time to do whatever needs to be done.
How to change low battery warning percentage
The same steps can be done on Windows 7, 8 and 8.1
- Click Start -> Control Panel -> Power Options
- Click Change Plan Settings
- Change Advanced Power Settings
- Click Battery menu
- Under Low Battery Level, change the low battery warning which is for showing the first warning notification (I set it for 20%)
- Under Critical Battery Level, change the value. This is for showing the second warning notification. (I set it for 15%, enough time for me to save the work that I am doing and close all applications before shutting it down properly or get a recharger to continue working. )
