This is normal for any notebook - it reduces power consumption to make battery last longer.
You can turn up brightness manually if you want to (usually an FN+F? key combination).

My mytouch 4g lcd backlight is dim but it gets brighter when i plugin the charger, is it the lcd? Or the connector to the lcd.


I'm not sure what a Mytouch is but on laptops if you don't have the power cord plugged in the display is normally dimmer or darker to preserve energy because it is running off the battery. You can make it brighter to some degree by pressing the correct keys on your keyboard. Once you plug the power cord in, laptops automatically display a brighter screen. This is all normal protocol.

Ahhh sounds like you have the infamous Nvidia GPU Video Graphics Card problem that is a known defect with many computer models including yours. The 3 blinking lights tells a technician that the video card is bad. You will either have to get another motherboard or have a repair shop to Reflow the Graphics Video Card. The laptop has to be completely disassembled to do it. Get a quote from your local computer shop then try the guys at: http://www.generalsystemsconsulting.com
They will repair it and ship it back cheaper than any quote you get including shipping.

Toshiba Satellite a205 the battery light started


I think you may need a new power supply, check this to make sure it is working OK, If this isn't working then the battery will not charge, and give symptoms you describe.

The screen brightness changes due to plug in or battery power


This is quite common actually I see it a lot. There really isn't any reason, it seems that when on batteries it trys to save power by Dimming Down, but it often just mucks up.. I always now set it via the keyboard keys. whenever I change from power adapter, to battery.

When i insert the powercord the bright ness will get dim


Its not a problem, its how it was designed. With the power cord in it will be at full power so it will light brighter, When the power cord is out, it will be less bright as its using power from the battery , it will light dimmer to conserve power.

Acer 4520 light going dim


Normally the way it works is if you plug in your AC Adapter to a laptop the computer screen will Brighten up since its no longer running off of battery and is actually charging . The reason why it should go dim is when you unplug the Ac adapter it goes dim to save battery life and last longer. If you are getting a really dim you can check and make sure that the Ac adapter jack on the adapter or motherboard isnt loose and it could be having contact to the unit and be loose inside and every small movement causes it not to charge / charge in and out and would cause this Dim effect. Again this depends on how old the computer is and I dont really think its the LCD or backlight going bad but you can try to mess with the screen brightness and If im not mistaken on that model it should be the FN key and the Right > and Left < Key for lower and higher brightness. Give that a try and check the adapter connection and you can pin point the issue . Hopefully it doesnt come worst to worst which could be a bad LCD going bad or damaged lcd internal cable. Hope my answer helped guide you closer to a solution.
