Lenovo g550 laptop with an external monitor would only display of broken original screen after crash dump

I have a lenovo g550 laptop with a broken screen, and use an external monitor (usually an lg flatron 1215s and sometimes an al1917c acer one). My computer went into crash dump a day after I installed and uninstalled a program called spybot search and destroy, so I ignored the blue screen msg (big mistake due to panic), and tried removing spybot once when I managed to reach the desktop. This happened a couple of times, and I think I managed to remove all of the program, before the blue screen came up again. This time though my computer couldn't display on/didn't recognize my external screen- only on my original and broken monitor, which is completely unusable (I can only see shaped and flickering lights). my external screen displays a msg saying it's in power save mode. It might also be useful to mention that a day before these crash dumps I had installed a new nvidia driver. I tried all the hotkeys and closing the lid right after starting the computer, but so far nothing has worked. My computer is still working (I can hear the fans and see a change in the colour patterns) and the external monitor worked when I tried connecting it to another computer, so what is the problem?

I don't think I have good news for you. It is very well possible that during the crash, more went defect then the screen alone. With a bit of luck, your hard drive has survived, because most of the time the drive has a G-force protection. But the bleu screen, you got, wanted to tell you something about the state of the computer. Like bad sectors, bad operating system, or can't connect to....
It could be the nvidia driver is not installed correct or what ever. You should be checking the monitor connections. outside the computer, but also inside the computer. But you should not check that whit the power on. Also check if the motherboard has any visual damage close to or on the video controller.
I think to solve this for a technician would be a real job, and if you don't have any electronic skills, I would not start opening the computer in the first place.
You then better visit a repair shop and ask them what it will cost you to repair the computer. In the back of your mind, start saving for a new computer.

When the computer is starting up PRESS & HOLD the "F" key which controls the external monitor. It may be F4, F5, F6. You should get image on the external screen. Go into video properties and select dual monitors or allow computer to use external display or something like that.

Lenovo g550 laptop with an external monitor would only display of broken original screen after crash dump

Firstly you need to get your external monitor working. Have you tried pressing FN+F3 while turned on, (may take several presses).

If you can get the external monitor working then you'll need to run windows in safe mode and try removing any new drivers you installed. or try a 'Last Known good' on start up this depends on the OS version.

Hi i have problem with my lenovo g550 ...after turning on ...the screen is white...could be a screen tape?

Welcome to Fixya

Try to perform power drain to the system. Take out the battery and unplug the power from the wall. Press and hold the power button for 15 secs. Plug in the power afapter then trun on the computer.

If same thing will happen, try to use external monitor and connect it to your laptop. If still no display then the problem is the onboard video card. If you get a display using the external monitor then the problem is the LCD. Could be loose flex cable inside.

Thank you for using Fixya!

Lenovo G550 laptop boots with a white screen??

Welcome to Fixya

Sounds like you already have LCD problem. Try to test the issue further. Use an external monitor and plug it to your laptop. If you get a display using the external monitor then the problem is the LCD. If there is no display coming out then the problem is the motherboard.

Thank you for using Fixya!

Blue thin line on lcd screen.G550 lenovo


There can be two reasons why this could happen.
1. The LCD screen might have gone bad.
2. or, There might a problem with your video driver.

To rectify,
If you have an external monitor, you can connect that to the laptop & toggle the display, so that you can see if the display is fine on the other computer.

Hope this helps..
Cheers!! Have a nice day!!!

Blue screen coming frequently in my ideapad g550.all programs suspended immidiately followed by restart of laptop.

Check to see what free space is available on your hard drive. If you have less than 15% free space, this will cause it to crash. Delete all unnecessary files, empty recycle bin, remove all unused software packages no longer used. You can also transfer data to an external hard drive to free up space.
