This is not a solution to your problem, but it will resurrect your screen. Turn off the Laptop, disconnect it from power supply if its pluged and switch off the battery from the Laptop. Then, with the battery outside, connect the laptop switching to power grid (of course, using your ac adaptor). This is like a weird hardware reset due to a strange problem between battery charging and operting Laptop. I'm researching that stuff because i suffer this problem too. If I found a definitive solution, I will comunicate here. We must investigate to find out where is the f...g bug!!!
If your screen has lost its brightness making it hard to see and your hotkeys are not working, go to your battery symbol on the taskbar, right click, then power options, then on the left side of the window there should be an option the adjust the display brightness. hope this helps =)

Re: Laptop LCD Problem
Hi, it sounds like physical damage has taken placed in the screen. You will need to contact the tech support of the laptop at this point. They will tell you whether or not it needs to be replaced. I'm sorry to say that damage to LCD screens on laptops is for the most part permanent.
Sorry for the bad news.

It sounds like the LCD on your screen may have burned out. Here's a few things you can try to verify if that is indeed the case:.
1. Unplug the power cord and take the battery out of the laptop. Then, press and hold the power button in for at least 30 seconds. That will drain the residual power from the system. Then, plug back in only the power cord - the battery should still be out, then try to turn the computer on. See if any video occurs at all. If the screen is entirely blank after a few minutes, go ahead an unplug the power cord again to turn off all the power to the unit.
2. Put back in the battery and power cord, and plug an external monitor or projector into the laptop. Turn the laptop on and then close the lid immediately after pressing the power button. See if any video will appear on an external video source. (IE monitor or projector). If video does show on the external monitor, then open the LCD screen back up and see if any video shows there.
3. If the video does not show on an external monitor at all, try the hot keys/function keys to swap the video output. (On your model of laptop if should be the F4 key.)
4. Also try the screen brightness keys. Press and hold F3 to increase the brightness on your laptop.
If these steps all fail - then most likely, the LCD is dead. You will need to either call HP to set up a return to depot repair - or contact a certified technician to repair the laptop for you. The number to call HP is: 866-234-1377. (This can be expensive if your laptop warranty is expired.)
Occasionally, you may find your laptop's monitor is too dim for your liking. A normal desktop computer's monitor has an on-board menu system that lets you adjust the brightness and picture control settings as you please. A laptop monitor has no such controls. You can adjust the brightness of your laptop monitor using your laptop's keyboard.
1. Press and hold the "FN" key on your laptop's keyboard. This is the "Function" key, which operates much the same way that the "Shift" key does: It allows keyboard buttons to be used for multiple purposes. It's located in the lower left corner of most laptop keyboards, next to the "Windows," "CTRL" and "ALT" keys.
2. Look at the top row of keys on your keyboard for a key with a tiny triangle pointing upwards and the symbol of a sun on it. This is the "Increase Brightness" key. With the "FN" key held down, press the "Increase Brightness" key. On most laptop keyboards this is the "F7" key, but it varies depending on the model.
3. Continue to hold down the "FN" and "Increase Brightness" key until your dim laptop monitor has reached the level of brightness you require. A laptop monitor can only get so bright. It will stop at its highest setting. 4. Release the "FN" and "Increase Brightness" keys. You have now fixed your dim laptop monitor.

I'm sorry my friend but seems your LCD monitor having problem. There are three options with your LCD monitor. Option 1: repair your LCD monitor *commonly problems are the LCD inverter*. Option 2: Replace LCD monitor with a new LCD monitor. Option 3: Instead using your dim LCD monitor plug CRT or LCD monitor external serve as your monitor. Have a nice day.
Try attaching an external monitor to the laptop & see if you could get any display on it. If this is successful, then you might have either a faulty LCD cable or screen inverter board. The
LCD cable transfers data signal from the motherboard & video card
to the LCD screen. It also supplies high voltage DC power to the screen
inverter board. The screen inverter board works as a power supply for
the backlight lamp mounted inside the LCD screen. It converts low
voltage DC power to high voltage AC power needed for the backlight lamp.
The screen goes black while in normal mode right? So try to boot in safe mode (power on then keep tapping F8 then select safe mode). Check if still happens in safe mode.
If screen does not goes black in safe mode it means there might be a software or driver causes problem when running in normal mode. You can try the following (update your anti virus software then run a full system scan, uninstall the video driver then download and install the latest one, uninstall any previous windows update or you can system restore to the time when it was working fine).
If the screen goes black even in safe mode they try connecting the laptop to an external monitor if still goes black, if yes then absolutely no issues with the LCD panel. You can try (uninstall and reinstall the video driver if still persist then this might end up replacing video card or motherboard, but before doing that update the BIOS first).
If does not goes black in ext monitor then the LCD panel might causes the problem. Reseat the LCD cable or inverter if you can.
If you have your Dell driver disc have to uninstall the video adapter driver and reinstall it. Restart the laptop and observe if things still happening. No need to do an update for the video driver though on this regard. Or on the other hand try to do a System Restore. Restoring your computer profile/settings on the previous date that it was working fine. But before you gonna do that have to back-up first the important files that you have to your external hard drive or USB flash drive. Hope these things help. Thank you.
