The computer's power management system automatically dims the screen when using battery power, which is one of the power-saving features.
To adjust the brightness:

  • Hold down the Fn Key located at bottom left of your keyboard next to the Ctrl key, and adjust the screen brightness using the left/right arrow keys located at the bottom right of the keyboard.
If that's not it then

A dim or dark screen does not necessarily mean a bad inverter! It could be a faulty lcd backlight bulb, inverter cable, inverter, or in some cases a motherboard failure. If your still under warranty then I would get Acer support on the phone and see what they can do.
An Inverter converts direct current (DC) to alternating current (AC).

Hi.

Sure you can with a standard VGA video cable.

Maybe you will have to change your screen resolution to get the best display layout.

Hope it helps!

Acer aspire battery does not recharge how to open


Are you trying to open the battery? is so then please don't it can be very harmful,

Does the system work when still plugged in? If so then the battery is bad, If it does not then there is an issue with the power port usually the solder breaks loose and is a quick repair for a technician,

However opening the laptop itself is virtually impossible to explain on here... Remove the battery sometimes there are small screws.

On the bottom of the laptop screws are usually grouped by letters or symbols.

Keep all like screws together. If there is anything we can do let us know,

Hi i've been using this laptop for over a year


If you can connect your VGA output to a regular desktop monitor and it works during the startup process, then it is probably you LCD screen. There is no way to know for sure that it is the backlight unless you replace it.

No LCD connectivity


Hello, I am using a Viewsonic lcd projector with my new Acer Aspire One. I did not have connectivity off the bat. Here's what I did: 1. Downloaded driver (unsigned, not the signed version worked - ie not os-specific) for the lcd projector to the Acer. Restart Acer. 2. With lcd projector connected to Acer, toggle function key & F5. But then, continue holding down the function key. A screen pops up with icons for laptop, laptop/monitor, dual monitor, and lcd projector. You continue to hold down the function key and then press the F5 key to move to the desired device. I had to repeat the same process to restore my Acer screen to the original proportion when not using lcd projector. I'm not sure if both steps 1 and 2 are necessary, but I did it simultaneously, so I'm not sure of the origin of success.

Broke lcd screen on laptop; need update to networked desktop, how?


If I understand correctly, you need to update your laptop??
Or get some files off it??
Anyway, connect an external monitor to your laptop and you can work on it that way. You may need to push a special function key to switch monitors. Check your keyboard.
In any case, connect the external monitor and turn it on, then power up the laptop.
