the best way to fix a laptop if the screen is broken is to plug in an external monitor into a vga dvi or hdmi port that is on your laptop this depends on your external monitor.
If the IBM laptop you use has a VGA port you just connect your monitor cable directly to the port. Then turn on the laptop and it should install the drivers needed to use the external monitor automatically. If you laptop does not have a VGA port then you will need a "Laptop replica port" to add the VGA port so you can connect the monitor.

The monitor screen is completely autonomous to the computer itself. If you're using a desktop computer and not a laptop, it's perfectly fine to turn off the monitor and leave the computer running. You cannot, however, shut the lid, sleep, hibernate, or do anything to a laptop an keep the downloads runnings. You can turn down the brightness on your laptop if you wish, but you can't shut it off entirely.
yes because there would be a button on the left or right of your laptop and it would have a button and press it then there you go
it depends on what kind of monitor
If it isn't going into "sleep" mode (in which case just move your mouse), you may have a bad capacitor or diode in the monitor.
