Check you standby battery of your laptop. If it doesn't store power from the power supply then it must be replaced. That might cause flicker in your desktop since the battery can't supply power to the unit and it is depending much on the power from the adopter.
Or if you are fun of logging off computer without proper log off process then it will destroy your battery and even the unit. Extra care must be given attention to your PC notebook because once you have problem with PC laptop, there are just two ways you can do, either fix it or throw it away. Others though, they have to sell it. Still others give that to Humanitarian organizations that needed it :)

Vertical lines showing up after being on for awhile


Eh, I can't be too sure, but it sounds like it's either a heat issue, a signal issue, or a backlight issue. Either way, if it's still under warranty I'd send it in.

My Toshiba M55 Laptop has a vertical 'ribbon' of flickering. Is it fixable?


Maybe your screen is going bad or the video card inside the computer is going bad. Try connecting another monitor to the computer to isolate the problem. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the computer. If the Borrowed monitor displays ok without the vertical ribbon then your lcd screen is bad and your video card is good. If the Borrowed monitor displays the same vertical ribbon as your lcd screen then your video card inside the computer has an issue.

The video will show on most systems when you reboot without you having to do anything. Some systems will require you to hit the FN (Function key) + F1 thru F12. Hold down the FN key then hit the correct key for displaying on the monitor (F1 thru F12). The correct key will normally have CRT/LCD on it or it will have the icon of a display.

Flickering multi-colored line in the middle of the screen.


You have a failure in the vertical deflection circuit. This could be either a bad vertical chip, the power supply that runs the chip or a bad capacitor in that circuit. This is usually a repair best left to a professional. There is a small possibility that it could be bad solder connections. If genlty tapping the unit temporarily solves the issue you can try and resolder the pins on the vertical chip LA7841 is the part number. There is also a resistor 1 ohm 1 watt. If that resistor is open you can assume the IC is bad

TV Flickers up and down and screen is shifted to the right w/ red color dominating the screen.


Hi
The most likely problem is the auto focus module.
A costly repair.
If you are going to fix it ask for a rebuilt one.
