Have you tried using an external monitor? Might be a video circuit problem. The usual solution is a motherboard replacement but some techy guys knows how to replace those video chips inside instead of the whole motherboard. In the country that I'm in they charge about $200+ for the fix.

My screen is black


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. Hope this helps

When my computer turn on the screen is black


your laptop is sending video through the hdmi/sata instead of to your laptop screen. Usually when you unplug the hdmi cable it will automatically revert. You have 2 options. One you can hook back up to your tv and use that as a monitor to go into your display settings and reset your laptop screen as the default. Second, you can start up the computer in safe mode and then change the display settings back to the laptop screen as the default. If you get into safe mode and you still dont see anything then the problem is most likely your laptop screen itself has gone and this is all just one big coincidence.

Hi

It seems that you need to use the latest driver for the graphic card.

You can do that through visiting the manufacture's website, choose your laptop model, OS, look for video (vga) driver, and download it.
Please tell us your results
Good Luck

Acer 5810t laptop. screen gone black


Press and hold the Power button for 45 seconds to turn the laptop off.

Then, remove the battery from the battery compartment and clean the metal contacts.
Next, reinsert the Battery and try to turn it ON.

If the display still doesn't come then you may try connecting an external display to check if the Computer is able to produce display and the issue is with the backlight of the LCD screen.


wish u good luck!!!!!!!!!!!

I have been fixing computers that has long beeps and short ones. It is usually attributed to memory problem connection. Open the memory compartment at the back of the PC then detach the memory card. Clean with cloth softly enough not to destroy the circuit board or a pencil eraser to clean-up dust that caused the connection blockade. Reconnect after cleaning.
