There is a Bios setting, it isn't hidden though. Config > Display > Brightness (high/normal).

Try that.

Brightness set to all the down


There should be a menu button on the monitor. Press this button, it has it's own brightness settings. Press the "factory settings" button; monitor should return to normal brightness.

Aluratek at107f , unit won't boot up


Had the same problem with mine the other day. Go outside in the sunlight or use a flashlight. Touch the menu hard key. you should hear it click. Using the bright light, click on settings, go to display, and turn up the brightness. I know this sounds elementary but for what ever reason, this device, when it goes into sleep mode, will adjust the brightness settings down. Hope this works for you.

If your laptop screen is not working and is blank, you are out of luck as far as working on your computer. However, while there may be a major problem you need to troubleshoot, there are some easy solutions to keep in mind as well, such as brightness settings and your power source.

1. Check the power source. While you have presumably already attempted to turn your laptop on and off, the problem may lie with your AC power adapter. Is the power-indicator light on the adapter on? If not, your problem may lie here. However, whether or not you have a power indicator light on your adapter, consider unplugging it and plugging it into another outlet. This may turn on your laptop and take care of your blank-screen problem.

2. Check your brightness settings. While it seems like a simple oversight, the brightness on your laptop may sometimes be turned all the way down. Thus, the screen appears to be black, off or defective, when the problem is simply that the brightness is on its lowest setting. To fix the brightness, check your laptop keyboard. Most laptops have the brightness settings mapped to two keys at the top left of the keyboard, accompanied by a symbol (often a sun). Use these keys to fix your brightness, but keep in mind that some laptops require that you press the Function key at the same time as the Brightness key.

3. Check the status of your laptop battery itself. There should be a battery indicator on the laptop that is connected to the battery. This indicator is either on the bottom of the laptop or (likely) on the side. If there is no indicator, your battery itself may be the problem, and may require replacing. Keep in mind that older batteries of the nickel-cadmium variety are more likely to decharge over time and forget their initial maximum charge level; this may be a particular issue to users of older laptops.

4. Find a VGA connector and hook up your laptop to an external monitor if the above steps have not alleviated the blank-screen problem. Turn on the computer and the external monitor. Does the external monitor light up? If so, the blank screen is likely due to a video subset problem/LCD problem in your laptop.

5. Consider that a deeper problem may exist if the external monitor did not light up This problem may lie in the motherboard. In this case, taking the laptop to a professional repairman or sending it off to the manufacturer is recommended.

I hope you find it very helpful. Best regards from fixya

Hi Dean,

Open your on screen display, used the +- buttons to go up & down. In this case used the - button to find the brightness setting. When you see reached the brightness setting press the first button ( the one you used to open the on screen) to activated the changed. Now used the + to adjusted the brightness to your desired. Well, hope i can help you on these. If not just give yourself a new LCD monitor for Xmas. Now a days...it's only cost about $200 for a 20" widescreen. Have a nice day!

Screen brightness


Usually by using a Function key. Look for a coloured symbol (like a sun). Press the coloured Fn key and hold it down, then press the Brightness button (usually two - one for up and other for down).

Brightness of picture


If you feel good about opening your set then you can try this: Look for the flyback (high voltage) transformer, with the thick red wire which goes to the top of the picture tube. There are 2 controls on the flyback transformer, focus (top) and screen (bottom)Turn the brightness and contrast all the way down and then increase the screen control until you see retrace lines, and then back it down until those lines just vanish. Return the brightness and contrast to normal and adjust the focus control, if necessary, for a nice sharp picture. Let me know if that brings your brightness back.
