Brighten lcd screen


OK, you are part right. The Fn key on most laptops is written in BLUE. This corresponds to the BLUE legends on various keys on the keyboard. MOST laptops have a pair of generic symbols for the screen brightness up and down . The brightness UP is a blue square (rectangle) with a large asterisk inside. The brightness DOWN is the same except it has a small asterisk inside. You will usually find these two keys as a secondary function of a function key.

Example: On my ACER netbook Fn+F6 = brightness UP and Fn+F5 = brightness DOWN

Brightness screen fn


Many computer users spend long hours online every day and don\'t realize that looking at a bright laptop screen can be hard for the eyes. If you spend a lot of time in front of a laptop screen, consider reducing the brightness of the screen at the earliest opportunity. There\'s a quick and easy way to perform this task so you can save your eyes as well as your battery power.

Press and hold the "Fn" key on the laptop keyboard. T his key is usually located at the top right or bottom left of the keyboard. Press the "Up Arrow" and "Down Arrow" keys, which are usually located in the lower right of the keyboard, to increase or reduce the brightness of your laptop screen. Adjust the level so that you can gaze comfortably at the screen without any glare. Disconnect the battery charger from your laptop and repeat the above procedure. On some laptops, the screen brightness varies considerably, depending on whether or not the device is charged.

MY Laptop Screen Is Dim It Will Not Show Bright


When you say that your laptop "screen is dim", do you mean that there is no light coming from your screen, but you can see images on it? or do you mean that there is light coming from the screen, just a very little amount?

If you can images, but NO light is coming from the screen, then the LCD backlight is dead, and it needs to be replaced.

If there is light coming from the screen, but it's very dim, then you'll need to find the screen brightness adjustment keys on your laptop. This is usually two keys. The first one is normally in the lower left corner of your laptop and should be a different color - like blue or purple, and will be labeled something like "Fn". The second key is normally in the function key row (F1, F2, F3, etc...) and has a symbol on it that looks like a sun or burst of light with an arrow. There's usually one for "brightness UP" and one for "brightness DOWN". Hold down the Fn key, and then press the "Brightness UP" key a few times to see if the screen brightens up. Good luck.

The screen is extremely dark on the e620, how do you adjust the screen brightness


Look for the symbol on the keyboard, usually on f4 and f5 that looks like a sun, it will be stamped usually in a light blue or purple color. Hold down the fn key which is to the left of your keyboard and use the F5 key or brightness symbol with arrow up to brighten the screen. If the screen still does not get very bright, it may be an inverter or and LCD Issue.

Dull picture on laptop but cursor is still bright


The screen brightness is automatically adjusted by your laptop's Power Management configuration in the Control Panel. Depending on your laptop's brand you might not only have the Windows power management, but also a proprietary power management application within the control panel or in your Start Menu programs usually listed under your computer's brand name. For example a program folder called "Toshiba" under Programs for a Toshiba laptop. Anyway, I would start there. Usually you can set up the screen brightness according to whether or your computer is plugged in or working on battery. Good luck! :)
