Windows 7: Notebook display brightness low when plugging out power cable?

Notebook display brightness low when plugging out power cable?

As long as the power cable is plugged in in my notebook the brightness of my display is fine.

But when I plug it out and use the battery the brightness becomes suddenly darker.

Why?

How can I prevent this switch-to-dark-screen?

I found no corresponding option in the power plans

Try going to the Power options and then click Change plan settings for your power plan then in the next window under battery at the bottom is a adjustment for brightness. Be sure to save changes one done.

Most laptops remember display brightness with power plugged and brightness when on battery, and switch setting depending on conditions.

So, when display is darker just raise the brightness, and it should remember that in the future.
