Question : Problem: "Low Battery - You should change your battery or switch to outlet power immediately to keep from losing your work"

    When running on AC power with a battery that will not hold a charge, the message "Low Battery - You should change your battery or switch to outlet power immediately to keep from losing your work" sometimes appears at the lower right corner of the display.  Occasionally, the computer goes into hibernation so that I have to press the power switch to resume.
     What can be done so that the operating system will not consider the condition of the battery when the laptop is operating on AC power?

Answer : Problem: "Low Battery - You should change your battery or switch to outlet power immediately to keep from losing your work"

In Control Panel > Power Option > check every tab there and setup power settings. Since you use AC only, you will need any feature to save battery life/shelf. Turn all OFF or disable. You should also find the hiber there, uncheck it, click Apply and Exit.

Other way is right click on screen and select properties, click on tab Screen Saver, and then Power, there you should see the settings.
