There's a setting smewher (can't remember where exactly) to do with energy saving. It can be sorted there.

Normally it is the other way round.

When a laptop is connected to the mains it works on "full power". So the screen is at maximum brightness and the CPU and other devices work at full speed.

When you pull out the mains lead and the laptop works on battery the laptop then dims the screen and slows the CPU and other devices down so they use less battery.

However this can be controlled in the "Power" setting on a laptop. Have a look for "Power options" or "Power settings" in the Windows control panel.

There is some info on power settings here, though you may need to look around for your version of Windows as you don't bother to tell us what Windows release you are on (or even if you are running an Apple Mac laptop)

not too a helpful answer, but mine is the other way around. I end up keeping mine plugged in most of the time just so I can see what I am doing. As VHG has said, I think it's to do with energy saving, so go to your control pnael and play around until you can change the settings

Some laptops remember different settings for the screen brightness, depending upon whether mains power or battery power is in use. The purpose is to allow the use of lower brightness (to save battery life) when a mains connection isn't available but it's possible to actually have a brighter setting stored instead.

Simply reducing the brightness (with the charger disconnected) might be all that is need, as the new setting should then be stored. That's normally achieved by pressing the Fn key together with whichever key has the 'darker' symbol on it.
