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.

My Acer Aspire 5551-2036 wont turn on blue light turns on screen remains black


Does it sound like the laptop booted up except the screen is black? Do you hear the fan running and the hard drive spinning? If so try the steps below.
Shine a flashlight on the dark screen to see if you barelysee the icons on the desktop. If so, then the LCD Inverter is bad.

Plug in an external monitor and see if the display shows up on it. It can beany kind of monitor even the old big fat crt monitors as long as it has a vgacable to connect to your computer's vga port. If so that proves yourvideo card is ok. The video will show on most systems when you rebootwithout you having to do anything. Some systems will require you to hit the FN(Function key) + F1 thru F12. Hold down the FN key then hit the correctkey for displaying on the monitor (F1 thru F12). The correct key willnormally have CRT/LCD on it or it will have the icon of a display.

If you see no icons by shinning a flash light and the external monitor works,then your screen is bad. If you see no icons by shinning the flash lightand nothing shows on the external monitor, then most likely your video card isbad.

All the lights turn on on the hp pavilion dv1000, but the screen remains black. Almost as if there was no power going to the screen. I have tried reseating the RAM and the HD. Problem still remains. ...


Hook a external monitor to the video output on the back of the laptop, if okay! there is a LCD problem with the laptop screen, causes! bad inverter board, or back light. If both show black! causes are Video Graphics Card that is part of the motherboard.

Screen is black..will not display anything. Any


You provided very little information, so I'll try to answer:
I assume you turned on the comptuer and it seems to be working-you didn't say.
I assume it used to display something-you didn't say.
Hook it up to an external monitor. Can you see something? If so, one of two things are wrong: Your LCD screen has gone bad OR you need to hit the Fn/Special function key combo that moves the display from your LCD to an external monitor.
If none of these solves the problem, then your video card has gone south on you.

Screen remains black


It seems to be the screen of the system has gone bad , but in case if you see DELL on start of the system, it can be OS which is corrupted but the way you are telling that you can see it on external display it it the Monitor.

Good Luck

Screen has no power


1. take a flashlight and light on the display after you started the computer and waited for about 5 minutes, if you can see the windows environment the inverter needs to be replaced (normally it's in the display frame under the display)
2. attach an external monitor to the laptop and boot. if the monitor shows something you don't have a defective graphic-card (maybe you must push fn + one of the fn-buttons showing a monitor)

if you don't get anything displayd by an external monitor the graphic-card might be defective - you would need a "new" motherboard then

Blank screen. Remains blank


Power down, remove the battery, remove the power plug. Hold down the power button for at least 30 seconds. Remove and reinstall the memory module(s). Re install the power plug and try to power back up and see if it works. If it does, reinstall the battery ad you're done. If not, get back to me for some more ideas and further diagnosis.
Thanks and have a good day!

POWER TURNS ON BUT SCREEN DOES NOT


Try Holding The Screen Up to A Bright Light And Look at it from an angle to see if you can see windows running without the light.... If you can..... The Problem Is Either Your LCD Bulb (needs Replacing) or It's the Power Inverter....

If.. You See No OS Running .. Just Black You Could Need Either A New Display ... or your Video Card/Chip is Shot...
Try Connecting an external Monitor if able to..... If It SHows Up On An External Monitor then Your Video Card/CHip is Good..

If You Get No Display, But The Black Screen Lights Up.... It Is Either The Display Cable Or The Display Panel Itself....

My monitor will remain black when notebook is powered up


Black uses much less power. It's a device for automation, so you really should not lavish the watts and attention on it unless it has to perform something truly novel.

If you really want to use the monitor though, you can use the function-key combination used to switch the display between internal and external displays.
