Laptop Battery.

[jrmelb]

Is there any software that will alert you to the power cord being disconnected from a laptop and/or to the battery reaching low levels.

Windows will alert you when your battery gets low, first will be a warning, then there'll be a critical alert, followed by standby, hibernation, or shutdown (depends on how you have it configured).

Control Panel->Power Options

Laptop Battery.

Not a direct solution, but works for me - I have different screen-brightness settings for battery and electricity.

In Win8 I get a full screen banner when the battery is down to 10%. But have a good look around the power options as 4wd suggests.

[Innuendo]

Isn't there usually an icon down in the system tray that shows whether you are on AC or battery?

It doesnt notify of the change though (power => battery).


FWIW just discovered it is a convenient way of getting to the power options though, via right-click.

The icon always changed on my old WinXP laptops.

^ yeah, sorry, I wasnt clear there: I meant no notification in a more in your face manner, e.g. popup. Taskbar on autohide here doesnt help either, but I dont know how the OP (who's looking for this) works, so that may be the solution.

[4wd]

Knowing what OS the OP is talking about would go a long way towards suggesting anything.

[jrmelb]

Yes - the OS is Windows 7.

YTOTPC^* - Pretty boring, any time there's a power state change it'll pop up a message box.  This could be connecting or disconnecting AC power.
