If the screen is cracked then you need to locate a online dealer to get a used
screen for your model.

If any water got on your system, make sure its thoroughly dried out before
turning it on.

Depending on how old the unit is, what ram you have, speed of the cpu, will
depend on the quality of the running OS.

yeah, it's probly around 3 years old or something.
im gonna try hooking up one of my extra monitors and see if thatll work.

Sure, you can replace the screen without a lot of trouble is you have
some basic repair skills and a little phillips screwdriver. Just take
the rubber feet off of the bezel that wurrounds the screen and you will
find screws under them. Take the screws out and you should be able to
work the bezel free to expose the insides of the lid. Then remove the
cracked screen and on the back of it you will find the part number of
it. Type that part number in the search box at Ebay and you will
probably get dozens of hits for that screen and you can buy one and fix
the unit as good as new.
