How can i fix my lenovo laptop with a black screen when turned on

Try following this video -

Hopefully there are 2x sticks of RAM inside your machine, take one out, turn the laptop back on, if the same issue persists, swap the RAM and try turning on again.

If this doesn't do anything it could be many many different reasons why it is doing that so the best option is to take to a repair shop

I searched the internet on "no display on laptop" which gave some informative results, but as only you know all the details of what is wrong only you can decide what is relevant.
I found the following interesting, but there are many more:

Does your computer beep more than usual when you turn it on ? Tis may be a sign that components are loose or have come out, or there is some fault which must be looked up.

To find out if it's your screen, connect an external monitor via the VGA port on the side of your computer Press the function button to select the external screen, or both, and if you get a display on the external monitor it's your screen or components associated with it, for example the 'inverter' or the CCFL if your computer has one. It may be that the display has become disconnected from the computer (there is often a ribbon connector). It may even be the graphics/video hardware on your mainboard. If it's the screen, you can replace it: detailed instructions for a similar model are here

If this is case you need to disassemble your computer and find out what is wrong with screen. The manuals for your computer can be found here

But you rea;;y need to find out what is wrong before you can even attempt to fix it. If you are not able/knowledgable enough to dissemble your computer, DON'T.

Restart your computer and then press and hold F8 keys until you get Advanced Options menu screen.Use the arrow key to highlight Safe Mode, and then press Enter, your computer will boot automatically to safe mode.
If you able to start in the safe mode then Scan your computer for viruses. Some viruses can cause a black Screen , especially ones that infect the master boot record (MBR) or boot sector.
Update drivers for your hardware. black Screens are hardware or driver related so updated drivers could fix the cause of the STOP error.
Return BIOS settings to their default levels. An overclocked or misconfigured BIOS can cause all sorts of random issues, including black screen.
If it doesn't helps you then simply get the system utility program like PC Fresher that will fix windows errors that cause of black screen screen

You turned on your laptop and horrors upon horrors, the screen is BLACK! You see that the laptop has power but besides that nothing is happening. I want you to know that there is a very good chance you can get out of this situation quickly and without any cost. This fix works on all brands of laptops:


• 1) TAKE OUT YOUR LAPTOP BATTERY
• 2) REMOVE YOUR AC ADAPTOR CORD, that's the wall power, remove it.
• 3) NOW HOLD DOWN THE POWER BUTTON FOR 30 SECONDS That will drain any static electricity that has built up on your laptop system board and many times fixes the problem of a black screen. After the 30 seconds re-connect your laptop to the wall power and hit the power button normally and see if the laptop comes back up. Replace your battery.

Switch back to internal monitor in bios setup or do both internal and external monitor.

Hi. I think you have uninstall your display driver and download the updated drivers on the Lenovo driver support website.

Go to this website and download the video driver for your laptop: http://www-307.ibm.com/pc/support/site.wss/product.do?doctypeind=9&template=/productselection/landingpages/downloadsDriversLandingPage.vm&sitestyle=lenovo
just make sure that you choose the correct or corresponding operating system that you have on your laptop (e.g XP, VISTA or Windows 7)

After downloading the video driver install it on your laptop then restart you computer. Goodluck!

Hi, try to boot into safemode, turn your system on then keep on tapping F8 to get the windows advance Menu screen, select safemode.

In the safemode windows go to Control panel and check your power options, you will see what time frame your system has for the LCD when turning off.

If this does not fix the issue, try booting into safemode with networking for you to be able to go online in safemode try updating your BIOS from your Manufacturers Website, Updating your bios may fix the issue.

Check your video adapter settings. try to set it on clone and see if the picture would appear the same on your LCD. From there you select it back to your LCD. Just make sure the primary display is set to your LCD and apply the changes.

Hope this helps.

Is the camera turned on? try to press FN+ESC at the same time to turn your camera on.

You probably have web desktop turned on. Or maybe you have the desktop icons turned off. Right click the desktop and select the view menu. See the options there.
