Hello and thank you for using Fixya's services.

I have a couple of troubleshooting tips for you:


First troubleshooting: If it boots up and is at least showing the splash screen (Dell splash screen or text) then it would be that the operating system is corrupt. This can be caused by several things included viruses, power surges or hardware failure.

The solution for this would be to take the hard drive out and slave it to another working desktop computer to retrieve your data. The attach the hard drive back on and reformat it (I can add specifics to doing this once I know the operating system).

Second troubleshooting: If you hear the operating system chime but do not see a picture and all the lights are on, then this would indicate that the back light on the screen is out. You can test this simply by hooking the laptop up to a monitor and see if you get a picture. If the computer screen shows on the monitor, then your back-light is out. If it doesn't show up then your video graphics card is out.

If the back light is out, it is easier to order a new screen (new or used) from eBay and just switch out (simple process and you can find a replacement for under 50 dollars on eBay). If it is the video graphics card, then you can also purchase one from eBay and switch out (a little tougher because you have to take the top of the laptop off). You can get assistance with this from the manufacturers website and pull specs for free.

Third troubleshooting: If you do not hear any beeps and the above solutions did not work. Then your motherboard has failed. This can be caused by surges or dust. You can purchase a replacement from eBay for a fraction of the cost and replace (this is tough and I am not sure if they have specs for this). You can do it yourself, just be sure and put everything back together as it was.

Fourth troubleshooting: To test the battery, take the battery out of the laptop and turn on with just the adaptor. If it boots, then the battery will need to be replaced. There is no way of testing the power adaptor but 85% of the time, this is the problem. Even if lights come on, the adaptor sometimes gets so overheated that it silently goes out but gives just enough power to make the lights come on. The power adaptor can be found on eBay for under 20 dollars and is cheap enough to replace (first) to make sure that is not the problem. The battery can also be found on eBay for under 60 dollars.

Please let me know if you have any questions and I will be glad to assist.

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.

I have lenovo g550...my screen flickers in every 5minutes...


Failing Inverter An inverter, typically found inside a laptop computer, consists of a small board, which has impregnated electronic circuits stamped on it. Inverters look like thin boards about the of two sticks of chewing gum. The inverter and its bulb control the intensity of the liquid crystal display, which lights the screen monitor. The computer can control the output voltage of the inverter and either lighten or darken the screen. A special type of inverter can adjust the brightness of the screen by using an internal sensor to judge the room brightness, and then adjust the screen accordingly. Failing inverters give off some specific warning signs, which can be recognized by observing different screen characteristics.

Short Intermittent Display Upon turning on the laptop, the screen flashes on in the normal mode for a short period and then blinks to black. A very faint image appears in a dark background, which will be very hard to see almost invisible. After shutting off the laptop and restarting, the same mode occurs, where the screen appears normal for a few seconds then fades to black. This condition points to a failed inverter. To confirm this, plug in an operational external monitor; if the external monitor functions, the inverter has failed. b> Total Blackout with Ghost image b> The laptop turns on, as indicated by the power supply button, but the screen comes up black. The screen comes up black after restart. You might be able to detect a very dim or ghost-like image on the monitor. When you plug in a known functioning external monitor, the external monitor operates normally. This mode of display indicates a failed inverter. b> Long Term Periodic Operation b> With this failure mode, the laptop screen illuminates normally upon start-up and remains that way after several minutes, hours or even days, until it goes very dark again. Brightness controls or restoration attempts do not work. Most often, the screen will function normally with a computer restart, but will eventually return to black. Faint ghost images might appear, as seen in the total blackout mode. b> Dark With Color Variation b> Upon computer start-up, the monitor shows black or dark gray, accompanied by very faint images. The screen might have an intermittent color change, or remain on with a non-standard color variation, like pink or red. b> Auto Control Switch b> If the screen appears black, with no faint or ghost images, look for the lid switch near the back hinge. The switch, when depressed with a closed lid, shuts off the computer and monitor functions. Sometimes the switch becomes stuck in the closed position, disallowing the computer and monitor to turn on when opened. Pushing the switch manually several times can often free it up. If the switch tab has broken or jammed inside the case, it needs replacing. b> Loose Connection In this mode, the display looks normal upon start-up, but tapping the side case of the computer turns the screen black. More tapping results in the screen functioning normally then cutting out again. This condition points to a loose wire connection from the inverter to the LCD backlight lamp, or the video cable. The connectors can be accessed by removing the monitor bezel screws and pulling the plastic retainer off. Both connectors can be cleaned and refitted.

I have a dell inspiron laptop, and a dell monitor hooked up to it, i turn on the monitor and it is very bright for about half a second then it becomes very dark, so dark that it looks like it turned off,...


Does the fault appear on the laptop screen aswell? It appears by your description that the fault is only on the external monitor. If the screen comes on for a moment and then goes blank as described, then this appears to be an invertor fault. It is very common among laptop and tft screens and requires the invertor inside the panel to be replaced / repaired. Simply plug the screen into another computer to confirm.

When my m45-s331 laptop is turn on for a long time, if i put the monitor off, maybe in not be turn on again and it's brightness become very low and hardly it can be seen! what should i do?


It's possible that the LCD lid close switch stuck in the "closed" position and the back-light stays off even when you open the LCD screen or turn on the laptop. The switch turns off the back-light when you close the LCD display to save the laptop battery power.

If that didn't fix it then there are 3 things that could have gone wrong:

1. Video cable connection from inverter to LCD got loose. To check this, follow instructions from step 3 on how to open the LCD and check if cable is fitted properly.

2. The video inverter is faulty
The screen inverter failure is very similar to the back-light lamp failure. In both cases the screen gets very dark and the image on the screen becomes very faint, barely visible under a bright light. If it's still under warranty, take it for a replacement. You can replace this otherwise - you can find the inverter under the screen, follow the procedure described at point 3 to open up the screen.

3. The LCD monitor is faulty
If it works on an external monitor most likely the LCD is faulty and needs replacement. If it's still under warranty, take it for a replacement. If not, you can do it yourself, it's pretty easy. Remove the rubber covers on the side of the screen, unscrew the screws take the plastic cover off, disconnect the video inverter and put in the new LCD after you connect the video inverter to it.
