LCD Display Monitor Problem
Laptop Screen Dim, Blank Or Black

Do you see a live BIOS splash screen? Most laptops will display a manufacturer splash screen with their brand name, Lenovo, Toshiba, Acer, Sony, etc, before launching into windows. Even those that don't should flash a text screen with the BIOS maker (AMI, Award, Phoenix) in the corner, and a message telling you what key combination to use to access the BIOS Setup screens. A biometric screen prompting you to scan a fingerprint before the system will boot counts as a BIOS splash screen here. If the screen lights up with anything, a graphic or text, it means that the basic display I/O system is functioning.

Is the screen live if you connect an external display? All notebooks should support an external monitor, usually with a high-density D-Shell 15 pin VGA connector, but some might feature a DVI connector instead. It's a vital part of laptop display troubleshooting to determine if a known good external monitor can be used. Newer laptops don't keep the external connector live by default, and some don't allow for simultaneous display on both the LCD and an external monitor. You can toggle between the notebook screen (which isn't working) and the external display with an Fn key combination.

Can you hear any sound from the hard drive or fans? If you can't get any life at all on the laptop lcd or the external display, it's entirely possible that the problem goes deeper than a video issue. Signs of life include the cooling fan blowing, the hard drive spinning up, any LED activity beyond the LED indicating AC power is attached or battery charging.

Do you see a very dim desktop image? Can you see a ghost-like image of your desktop that is functional, ie, one that changes if you drag an icon, launch a program or disappears if you shut down. Standard LCDs produce very little visible light on their own,
