SOLUTION: If you have a second computer, use Remote Desktop by choosing 'Run', type 'mstsc', type the name of the computer with a black screen, and connect. After logging in, open 'Control Panel', and choose 'Power Options'. On the left panel choose 'Choose when to turn off the display'. On the row labeled 'Adjust plan brightness', under the 'Plugged in' column, turn up the brightness slider.

Every laptop is different, so adjusting the brightness or contrast on your laptop may vary from the steps provided on this page. However, understanding the process of how to adjust the brightness or contrast will help you change your settings.
Most laptops adjust their brightness and other settings using the function key in conjunction with another key. For example, pressing and holding the function key (abbreviated as "Fn") and pressing the up or down arrow keys as shown in the picture below, increases and decreases the brightness.

Screen is dull while on ac power. When running on battery screen brightens up but battery does not last long. Power supply is supplying 19.17 volts which but on the power supply is written 18.5 volts.


ery adjusting your brightness via the function keys on the keyboard also under power settings see if screen is set to save energy when using ac power usually this is set to save power when on batteries it just might be reversed on your machine

How do you make the lighting on the screen brighter without the charger in ?


The screen will automatically dim slightly when it is on battery power, this is to conserve battery power. For maximum brightness connect the power adapter into the laptop.
On the Thinkpad laptops you can adjust the brightness by pressing and holding down the blue Fn key plus the Home key to brighten or the End key to dim the screen.

Dell laptop screen goes blank when ac adapter plugged in


I believe I have found the problem with the 1525 that I am currently working on which has the same problem that you describe. Ultimately I think it's a problem with the inverter in the LCD. When the laptop is powered by battery the brightness is lower than full. When I plug in the power adapter the brightness goes to "full" and I hear a faint sizzle and the LCD's backlight goes off. Same as if you hold the Fn key and press the up arrow to brighten it, it will do the same thing when you reach near the full brightness. So for now I have fixed this problem by going in the Power Options and clicked on Adjust the display brightness on the left. Slide the slider to the left on the "plugged in" part and now when you plug it in it shouldn't make it go blank. I do want to note that I hear a faint buzz coming from the LCD when I plug it in. That must mean the inverter is faulty. WAY TO GO DELL!!!!!!

Display brightness


Ok on your keyboard there should be some way to adjust the brightness just plug in the laptop and adjust it to what you want then unplug the laptop and adjust it to what you want and it should keep that setting. if that does not work you can check the bios settings some laptop bios' have a brightness option.
