Blank screen


Did the laptop boot up all the way except the screen is blank? Do you hear fans running and the hard drive spinning, lights on? If you think it booted except the screen is blank try the steps below.

Shine a flashlight on the dark screen to see if you barely see 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 be any kind of monitor even the old big fat crt monitors as long as it has a vga cable to connect to your computer's vga port. If so that proves your video card is ok. The video will show on most systems when you reboot without 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 correct key for displaying on the monitor (F1 thru F12). The correct key will normally 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 light and nothing shows on the external monitor, then most likely your video card is bad.

Dell Inspiron8600 display is blank. It begins booting, the screen flashes with the Dell logo then it goes blank. I can see faint images on screen but can't read anything. Can I hook up to an external...


If you get the boot image on your screen then you screen is working correctly unless there's something that you not explaining. You can try an ext. monitor if you think it is something related to your LCD screen not woring during boot up. If the ext monitor not showing your laptop to boot then you have problem with your OS and may need to get it repaired or restored.

Black blank screen Lenovo 3000 N100


You say the laptop all of a sudden flashed off.

How old is the laptop? You may have suffered one of two things? First of all, if the hard drive will not boot back up, even after using the recovery discs, then that would explain it powering off. I have seen this happen on old desktop hard drives.

Next, try to get the transformer or adapter tested. It may not be putting out enough amperage to run the laptop.

Is your HDD LED flashing? -Try pressing F8 on startup to show the boot menu option of your OS if it is Windows. If it does appear use Safe Mode first. If not successful try re-installing your OS.

Screens works for 5 mins then goes blank!!!!!


It could also be that the video card is not compatible with this monitor. After the pc boots up, can you get into windows? Does the monitor always go out at a specific time on boot? Say for example; you boot the pc, windows startup splash screen comes on; screen does a quick flash and goes blank. Then it maybe the BIOS setting for the video. Try changing the IRQ setting. You could also try putting the video card in another slot. Do you have the manual for the motherboard? Ray
