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 info on my external screen- only on my original and broken monitor, which is completely unusable (I can only see shaped and flickering lights). 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?

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.

SOURCE: Screen Flickering on Acer 3680-2682

Ok we must remember when we setup any device on our PC, one of the many non PnP devices is and LCD Monitor, your PC should always be shutdown before installing a new Monitor. If you did not do this you could have damaged the I/O port on your PC. Not a definite, but possible! When you plug up a monitor or any serial cable while the PC is still on, it is of a low voltage which can casue some issues for you! Sounds like this one is yours!

SOURCE: Acer Aspire 5580 wont power up at all

Remove the adapter plug. 
Remove battery and insert again. I use a USB optical mouse, when inserting the battery, the lights will flash a moment. That signs OK.
Try turn on the notebook.
For my 5580, this trick always work. After it is on, I plug in the mains.

SOURCE: D800 laptop will not display on external monitor

Most laptops go into standby mode when the lid is closed. To stop this, (Windows XP) click Start, Control Panel, Performance and Maintenance, Power Options, then click on the Advanced tab, select "Do nothing" in the drop-down for "When I close the lid of my portable computer"

SOURCE: Gateway W340UA laptop - no display...

Sometimes it di happen , specialy in most laptop which is being used more frequently and longer usage, the advisable use of a laptop is atleast 2 to 4 hours then shut it off and have cool down for 30 minutes to one hour then you can used it again, unless you got a support inclined base for laptop with support ventilating fan to help down minimize the heat accumulated during the usage.

have it check your video card with the proper technician, but first try to cool down your unit and try to open it again, and if still does'nt work then have it check by the service center

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.

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.
