Your backlight is probably burned out. It is repairable, but I recommend having a computer repair shop take care of it.

Twenty plus vertical lines in my IBM G40 monitor is there any solutions to clear those lines?

Hi there.
If the line appear from the moment you switch on your Laptop then your screen has gone faulty and will need to be replaced. Other option would be to use external screen.

IBM Thinkpad R51, screen went dark. At the right screen angle, I can see some light from the windows and cursor, but very faint. At that light angle I can maneuver the mouse and click on windows, so all...

The problem
1 The LCD screen is out or
2 The invertor board behind the LCD screen is out or
3 The backlite is out

You have 2 options
1 To use an external monitor for the time or
2 get the laptop fixed by a tech shop

IBM G40 won't reboot

Unfortunately only few people know your problems solution but I'm happy that i can help you.

Its simply a problem of setting HDD ( Hard Disk Drive ) type which can be changed using BIOS setup. I hope your laptop must have SATA but if its not working on current settings then please change it to another options available.

Surely, your system will get booted after that and furthermore you can re-install your windows again...

Rate this solution if it was helpful to you.

Adding a monitor to ibm thinkpad using ubuntu

When you connext an external monitor to the laptop, power up the monitor then power up the laptop. The video infomation should automatically divert to the extermal monitor. You can toggle between the external monitor and the LCD screen by pressinf the blue Fn key + F7 key.
If you cannot get an image on the external monitor, then it is likely the video card is faulty and you can fix it by replacing the motherboard, but what is the point when the screen is broken also.

Graphics cards on laptops cannot be changed or upgraded. In order to do this, I believe you have to change out the screen, because graphics cards in laptops are within the screens.

Back light

If there is one backlight bulb it should be in the bottom fo the screen, if 2 than 2 on the top one on the bottom. I want to point one thing though, if you break the seal around LCD screen that will defect picture quality, I if you are having issue with backlight there is the greater chance that the cable is broken in place where it folds when you close you laptop, rather than the bulb going out. So check the cable first if the cable is not the problem than change entire screen than just that bulb.
