Cannot get my acer screen bright. Its really dull the battery is charged to its full amount.

you can change that in power settings right click on the battery bottom right of the screen hit change power settings u will get options u want to change power settings look at the options you want to make it stay brite all the time right now you have it set to be brite only when plug is in change the option when its unplugged to brite also

The power/battery settings are set for powersaving, rather than performance, so the battery lasts longer. If you set it to performance, the screen will stay bright.

Hello,

It really sounds like you have a short in the ac adapter. Laptops dim the backlight on the screen when on battery power and go full brightness when on AC. I think your adapter is going on and off. When it is on the screen is on full and when it goes off the screen dims down a bit. You could have a bad adapter, most likely, or a bad charging jack in your laptop. Check the adapter first, just use a multimeter set to voltage. Read lead goes to the center pin and black lead goes to the outside metal contact, you should get a reading of 18 to about 26 volts. Move the wire around near the plug that you are holding and keep checking the readout. I think you will find the voltage dropping as you move the wire.

I hope this helps, If so please rate my solution.

check on the keyboard, lots of the keys have an extra function, normally written in blue.

Look for the two that show brightness... it the same symbol on TVs that sets brightness...

now look for the "FN" key.

press and hold the "FN" key and then press the brightness + key... this should make the display brighter...

well...dull screens are usually due to either low power or a bad video card..check the power supply to be sure its charging the battery

hi dear,
Try to reset the Bios settings on the laptop... dont worry.. shutdown the laptop restart it and press F8 on the key board.. continuously... Once you are at the Bios and Cmos settings find a way to reset all the settings to default...

the brightness light might gone bad. u have to examine the system by a authorized service centre or some qulified technicain.  may be hey could repair it without replacement of screen.

Well, Declan try go to your display properties by right click on your desktop then left click properties. Go to settings tab and click the troubleshoot button.

Im afraid to say this however, its possible the your monitor has a problem because most laptops and as well LCD's and Flat Screen TV's have its disadvantage of its lifespan. Since these types of screens have limited feature especially on display that it doesn't distribute the light image very well inspite of its low radiation to give our visual taste more better and more clear. That's why that most of these types of monitors won't get your eyes strained. But when it comes to durability, it much lesser advantage to compare with CRT monitors.

<Fn> + <→> Brightness up Increases the screen brightness.

<Fn> + <←> Brightness down Decreases the screen brightness

If tese dont work either your LCD lamp or board may be going bad.

If the brightness is dull even when connected to the mains, it maybe that your back lighting is faulty on the screen and you will need a qualified repairer, although it may be worth looking at a new notebook depending on the cost.
