Check all the connections on the power cord. Also try wiggling the connection on the back of the laptop. Sometimes the are pulled out just a little.

What causes laptos to not show display despite showing that they have switched on?


Step 1:
The display on your laptop is the interface through which you interact with and control your computer. If it is not working, your laptop will become virtually impossible to use. A laptop is a computer, and like all computers is subject to both hardware and software problems that may affect the display. Before taking your laptop in for repair or getting rid of it, you should first check the display yourself to see if it needs to be replaced.

Check the laptop's battery and power cord. If the laptop is out of power, the display will not work. This usually happens if the power cord is unplugged and you were unknowingly running your laptop on battery power. Check to make sure the power cord is plugged in and that the laptop has power. Many laptops also turn off the display if it is being powered by its battery after a period of nonuse. Touching any key will usually turn the display back on if the battery is not drained. Restart your computer. If a software program is stuck or malfunctioning, it may cause your display to stop functioning. Press and hold the "Power" button on your laptop to reboot your computer. If the problem was a malfunctioning program, the display will turn on after the computer restarts. Check the brightness level of the display. If the level is too low, the screen will appear dark. The brightness controls are usually located on two function keys, such as "F9" and "F10." Look for sun or light icons on the keys. Press the key with the larger icon to increase the brightness level. Alternatively, on some laptops hold the "Fn" key while simultaneously pressing the "Up Arrow" key to increase the screen brightness. Check the display closed switch. Many laptops have a small button that senses when the LCD screen is closed and puts the laptop in sleep or hibernation mode. If the switch gets clogged with dirt, it may get stuck in the closed position. This will result in dark display even when the lid is open. The switch is usually located near the hinges of the lid. Spray the switch with a can of compressed air to loosen the dirt so that it will resume its normal operation. Plug an external monitor into your laptop. If the problem is not software related, the external monitor will display the laptop's screen. Connect the monitor by plugging the cable into the VGA, HDMI or DVI port on the laptop. Press and hold the "Fn" key while simultaneously pressing the "F8" key. The video output will be directed to the external monitor if there is a hardware problem.

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.

Have acer one message says to plug into ac adapter


Check the AC adapter and power cord. It sounds as if either one end of the cord near the transformer box is loose, or the end that plugs into the computer is loose/not connecting properly.
Failing that, make sure the wall socket you have the cord plugged into has power (try plugging something else into it). If everything I mentioned checks out, there could be something wrong with your battery.

Will,

It sounds like the LCD on your screen may have burned out. Here's a few things you can try to verify if that is indeed the case:.

1. Unplug the power cord and take the battery out of the laptop. Then, press and hold the power button in for at least 30 seconds. That will drain the residual power from the system. Then, plug back in only the power cord - the battery should still be out, then try to turn the computer on. See if any video occurs at all. If the screen is entirely blank after a few minutes, go ahead an unplug the power cord again to turn off all the power to the unit.

2. Put back in the battery and power cord, and plug an external monitor or projector into the laptop. Turn the laptop on and then close the lid immediately after pressing the power button. See if any video will appear on an external video source. (IE monitor or projector). If video does show on the external monitor, then open the LCD screen back up and see if any video shows there.

3. If the video does not show on an external monitor at all, try the hot keys/function keys to swap the video output. (On your model of laptop if should be the F4 key.)

4. Also try the screen brightness keys. Press and hold F3 to increase the brightness on your laptop.


If these steps all fail - then most likely, the LCD is dead. You will need to either call HP to set up a return to depot repair - or contact a certified technician to repair the laptop for you. The number to call HP is: 866-234-1377. (This can be expensive if your laptop warranty is expired.)

I hope this helps you out!

NO VGA DISPLAY TOSHIBA SATELLITE M300 FOR VISTA


Hi What precisely do you mean by VGA display, is your laptop not displaying anything on lcd screen,or its having problem giving display on an external monitor connected via a vga port.
if there is no display on the laptop LCD screen, then turn the laptop on and observe for beeps sounds and hard disk spinning sound if still no display is available plug the laptop to external monitor and again restart the laptop. if there is no display on the external screen and laptop is displaying well in LCD, Then most probably you need to press some keyboard combination on laptop keyboard eg: Fn + f4 , refer to your laptop manual also.

My eee pc 4G surf won't turn on. It started having problems when the power cord was bumped - causing it to immediately shut down. Then it just stopped booting all together. I replaced the power cord and...


Most likely, either the power jack inside the machine (jack itself or solder joints) or the plug on the power cord was damaged; obviously the plug is only a few dollars to replace, the jack also only a few dollars, but much more labor intensive. My experience tells me it's probably the power jack. If you have any way to externally charge your battery and, using it, find the machine operational, that pins it down pretty well. When the external supply is used, the internal battery is supposed to be switched out of the load circuit and into charging mode.

I have an Acer Aspire one model zg5- Power cord


Here is another thing you can try. Unplug the power cord, and then remove the battery. Press the "Start" button and hold for 5 seconds. Replace the battery back into the computer and plug in the power cord. Start the machine and see if the low battery message still comes up. Sometimes the program that monitors the battery status gets confused. Doing the above should straighten it out. The Acer should start up and the AC power light should be lit. Look down in your task bar for the battery Icon or go to Battery Status in Control Panel and see if it shows that the battery is charging. Even newer batteries can go bad (rare) but if this is the case and a cell has shorted out in the battery, then your only recourse is exchange under warranty.
