A blacked-out screen doesn't necessarily indicate a broken monitor.
If the computer has run out of charge or is in hibernation or sleep mode,
if the screen is too dark, or if the display cable has come disconnected from the motherboard, the screen may appear black or fail to turn on. To fix a blacked-out laptop screen, troubleshoot the screen settings, check the LCD connector and see if the computer is awake and receiving power.
Touch the touchpad or move the external mouse to see if the computer is asleep or hibernating. If the computer fails to respond, press "Enter" on the keyboard. Press the power button if the screen remains black.

Confirm that the power indicator light, found at the front of the computer or above the keyboard, is glowing solid green or blue. Confirm that the power adapter is plugged into the computer and into a wall outlet. Confirm that battery indicator light is glowing solid green or blue. Hold down the "Fn" key. Press the up-arrow to see if the screen brightness increases.
Some computers also use the "F6" or "F7" keys to increase screen brightness.
Hold down the power button for 10 seconds to turn off the laptop.
Remove the AC adapter from the computer, close the screen, and then turn the PC over.
Slide the battery latch to eject the battery. Pull the battery out of its compartment. Turn the computer back over, open the lid, and insert the edge of a flathead screwdriver or other flat, solid object beneath the bezel above the keyboard. Wedge the edge of the keyboard bezel off of the top cover.
Work your way along the edge of the keyboard bezel to loosen it.
Pull the bezel off the laptop.
Trace the cable coming from the laptop screen to the connector found beneath the bezel. Reconnect the display cable to the motherboard if the cable has come loose from the connector. Line up the tabs on the bezel with the slots along the top of the keyboard. Insert the right edge of the bezel into the gap above the keyboard, and then push the bezel back in place. Turn the computer back on. If the laptop screen is still blacked out, connect an external monitor to the video port on the side of the PC to confirm that the video card isn't defective. If the external monitor works, the LCD screen could be broken. If the monitor doesn't work, the motherboard or video card might need to be replaced.

Download the appropriate BIOS update and flashing utility for your motherboard from the motherboard manufacturer's website. Most manufacturer websites keep the files under a section labeled "Support." The files will likely come in a ZIP archive, so you will need to extract the files to your desktop. Copy the flashing utility and BIOS file to the DOS boot floppy. If your computer does not have a built-in floppy drive, you will need to connect a USB-type floppy drive first by plugging it into a free USB port. Rename the new BIOS image "newbios.bin" to make remembering it easy. Reboot the computer with the boot floppy in the floppy drive. Restart your computer repeatedly tapping the f8 key to enter safe mode while the screen is black once in safe mode where the only things working will be your keyboard and mouse allowing you to attempt to repair your computer
If done properly the user should get to a screen similar to the below screen. Select the option for Safe mode command prompt only Windows Advanced Options Menu
Please select an option: Safe Mode
Safe Mode with Networking
Safe Mode with Command Prompt Enable Boot Logging
Enable VGA mode
Last Known Good Configuration (your most recent settings that worked)
Directory Services Restore Mode (Windows domain controllers only)
Debugging Mode Start Windows Normally
Reboot
Return to OS Choices Menu Use the up and down arrow keys to move the highlight to your choice. Select safe mode with command prompt When the boot process is done, you will be at the "A:\" prompt. At the "A:\" prompt, run the flashing utility. For example, if the flashing utility is named "awdflash.exe," then you would type in "awdflash" and press "Enter." The flashing utility will likely have a simple graphic menu system with a list of the commands and what they do. Save an image of the existing BIOS to a file called "oldbios.bin." Once the backup is complete, point the flashing utility at the new BIOS image and start the update process. Remove the DOS floppy and reboot the computer when the update is complete.

Toshiba tecra p5 up on black Screen on PCI EXPRESS ERROR can't boot????


If you can't boot to the bios, you are in major trouble. You can try and see if the manufacturer has a bios flash program you can load on a Flash drive to flash the bios...you will have to research that on another computer, obviously.

Black screen of death


What do you mean "Flash Bios"? If you have updated your BIOS and it has failed, that is it. You need to fit a new programmed BIOS chip or the mother board is toast.

Flash the bios


DO NOT FLASH THE BIOS PROGRAM

Not trying to be rude, making a statement

Tell me about this laptop.

What is the model name, and model number?
Example, Acer Aspire 5552
Model number is on the bottom of the laptop.

Just black screen one day?
Had problems leading up to it?

Post back in a Comment.

joecoolvette

[1) When flashing the BIOS, and power goes off?
You're DONE, unless when asked you saved a copy of the original BIOS; to go back to.

2) Wrong BIOS update? (Flash the BIOS)
BIOS update too new, or not compatible?
You're DONE unless you saved a copy of the original BIOS.

Too easy to turn that laptop into an expensive paperweight.

It is a fact that about two weeks after a laptop, or desktop computer hits the market; that there is an updated BIOS program for it.

But read the above again ]

Failure of both (dual) bios after updating


Sorry bud, when you flashed the BIOS it obviously did not like it..Nine long continuous beeps is ROM BIOS checksum error. Another words you need a new CMOS chip as you cannot backdate a flash BIOS. You can't boot from any disk because the boot process never even gets to the part where you can use your system. BIOS is first when you start up and if you can't get by it then nothing will work. The only advice is use this as a good learning experience and make a backup of your BIOS in the future. Good luck..don't shoot the messenger. Please rate this solution before you log out.
