Tip & How-To about Computers & Internet

Monitor is Black, Computer won't boot, computer screen is black.

If you have power and you hear your computer running but screen is black, your cables are connected and screen power button is on, No dots, dashes, words at all, usually that indicates the graphics card or ram is blown. Much more rarely a bad CD/DVD drive defect can block motherboard monitor drive.
Usually there is a used computer parts dealer in major cities and fault confirmation can cost under $10.00 if you can switch graphics cards yourself. Take your card in with you for slot style matchup. Nearly all computers can handle a card switch without data loss. Labor and time saving to try a card with Windows drivers resident, buy a universal or common brand.

vostro 1000 black screen an i can hear it running, but can see..


A blank screen with evidence that the motherboard is working (the Capital "A" green light is probably the CAPS LOCK on your computer's keyboard) initially points to an output or video problem. One quick way to see if that is the case is if you connect the computer to an alternate screen. Do so with the "sick" computer powered off at first. After being sure the connections are snug, be sure that the test monitor is powered on and then turn on your "sick" Dell. If the test monitor runs as your laptop's monitor ran when it was healthy then you know there is a cabling/backlight/inverter/screen problem. Some of these can be solved very easily, some more expensively as replacement may be required.

On some laptops pressing down firmly on the keyboard may seat a screen cable to motherboard connection. That often works on IBM Thinkpads with screens that fade in and out due to a poorly seated screen cable connection to the motherboard.

So let's see how the test to a known working screen goes.
