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

My computer screen is black after logging in and i cant do anything i have windows vista


Hello

This usually occurs when your RAM is faulty and can actually happen to all computers running many different operating systems. Aside from installing a new operating system to test out the RAM, you can simply switch out your RAM.


Turn off your computer if it is on. If you are experiencing the black screen regularly, there is a good chance that it will not allow you to boot up your computer fully without shutting itself down. If this is the case, your computer is already more than likely off. Remove the power cord from the computer tower.

Remove the screws that hold the PC tower cover in place with a screwdriver. The tower cover usually only comes off on one side, so gently remove the side that is capable, and place it away from the tower. Users with laptops need to remove the RAM panel from the underside of the computer. This gives you access to the RAM for replacing.

Locate the RAM that is attached to the motherboard of your computer. You will see clasps that hold the RAM into place, and you may see more than one stick of RAM. Remove all of the RAM sticks by pushing the clasps away, unhooking the RAM from the motherboard. Click your new, replacement RAM into place, and cover the tower back up with the cover, or replace the laptop RAM panel.

Hook up the power cable or place the battery back in, and power on your computer. You now see that your computer is working without the black screen appearing. If you have more than one stick of RAM, turn the computer off, and remove the power cords and battery. Insert one old RAM stick, and cover the tower back up, replace the power cord or battery, and turn on your computer. Check to make sure it does not present you with the blue screen. One by one, reinsert the old RAM sticks into your computer, and test your computer for stability. Once you are presented with the black screen, remove the last old RAM stick that you inserted, and your screen problems are gone.

The screen is black, i removed the battery and


Hi,
Turn the computer off and then disconnect all the external devices like (printer,usb devices etc)connected to the computer along with the cable for the internet .Then disconnect the cable for power that would be right on top at the back panel of the computer tower and with the power cable disconencted press and hold the power button for atleast 30 seconds.Turn the computer on if it takes you to the desktop then it means that there is some external device that is causing the computer not to come up to the desktop so find which deveice has gone bad check it by conecting one device at a time.
Next thing that you can try is turn the computer off and then when you turn the computer on or as soon as you press the power button to turn the computer on start tapping the F8 key repeatedly until you get a black screen that says advance boot menu option .Then used the arrow keys on the keyboard and highlite the option that says safe mode and hit enter,select the operating system and then when you get the log on screen select administrator .If it takes you to the desktop then you can try doing a restore by going to start?all programs ?accessories?system tools and then system restore ? select the date when you think that you r computer was working fine and then click on next next to exit from the wizard.Should fix the issue .
If the computer does not boot up to the desktop then without wasting time on any trobleshooting steps recovery needs to be done that takes the computer back to its original factory settings.To do this instead of the f8 key tap the f11 key till you get the screen that says system recovery ,click next until you get the screen that has advance option ?click on it ?select destructive recovery ?click next the recovery will start and the computer will be formated (whatever you have added after you bought the computer would be lost) ?If the recovery does not work this was then it needs to be done from the recovery disks and fot that you call call HP
all the best..............

Power Save mode on, can not use computer


If your computer is indeed running, simply unplug your monitor from the wall, and then plug it back in. This will bring your monitor out of power save mode instantly.

When you star it is black screen and stay black


If nothing is happening, it is related to the power. Make sure that you are using a electrical outlet that is working (use a light to test). Unplug the power cord from the back of the computer, as well as from the wall socket, and then plug it back in with authority... making sure it has a good connection on both ends. You may also use another power cord (but rarely would be the cause of the problem). If there is no action from the power supply when you press the on button, then the problem must be with the power button or the power supply. I would lay odds that it is the power supply, replacement should cost about $30.

Hope this helps. Best Regads, -md
