My screen is black
When you plug in the power cord is there any lightswhatsoever on the laptop, where the plug goes in or on the AC Adapter of thepower cord?
When you press the power button do you hear fans running, hard drive spinning,lights on the computer, hear any beeps or lights constantly blinking, hear theDvD/CD drive click and the light on the drawer of the DvD/CD turn on for asecond or two? If so the laptop is trying to boot or may have booted, butthe screen is not showing for some reason.
Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous.
Maybe your power cord is bad if you don't get anything to happen whatsoeverwhen you press the power button. And if that's true maybe you wasoperating off the battery the last time you had it on and since the power cordis bad, it was not charging the battery so the battery is drained and the powercord is bad.
Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove theBattery, then Press and Hold the power button for 30seconds. After 30 seconds plug the power cord back in (leave the batteryout) and hit the power button to see if it boots. If it does, you can putthe battery back in and let it charge.If it seems like the laptop is up and running but the screen is not displaying anything then the issue is with the screen. Take a flashlight and shine it on the screen and look very hard and you might see the icons or something very faintly on the screen. If so, your LCD Inverter needs to be replaced. It is located at the bottom of the screen and covered by the strip that goes around the screen. IIf you don't see anything on the screen then try plugging an external monitor to the laptop. I can be any kind of monitor, even the old big fat crt's as long as it has a vga cable that can go into your laptop's vga port. If you see the image on the external monitor, that means your video card is good and the screen needs to be replaced. Sometimes you might have to hit the FN key plus one of the F1 thru F12 keys to get the image to display. The correct F1 thru F12 key will either say CRT/LCD or it will have the icon of a display on it. Press and Hold the FN key then hit the correct F1 thru F12 key. This will toggle the the image to display either on the computer's screen, the external monitor screen, or on both screens.
