ok so my computer's screen stays black, but the on button lights up and i can hear the windows welcome noise, so i know its on. i think i know why this is happening, because i recently messed with the power settings and changed the option to go to standby when the laptop is not running on outlet power. so i realized that i need to just plug it in, but now it doesn't respond to the outlet power. usually a little lightning bolt lights up on the comp when it's plugged in, but not anymore. can someone please help on why this is?

Try taking the battery out of the computer, then reseat it.
Also if you can have someone verify the AC transformer is putting out voltage.
I am not much on laptops at all.

Get a multimeter and see if the AC Adapter is putting out the correct voltage (it'll be written on the AC Adapter)
Check the place where the plug plugs into the laptop - does it feel loose if you gently wiggle it?
When you wiggle it, does the charging light come on at all (even a flicker)?

The most common problems here are a broken AC Adapter or a broken plug inside the laptop. A new AC Adapter costs about the same as a new battery - but it may be better to let a PC shop take a look at it for you. Some PC shops can repair a broken socket of this type right in the store, while others may have to send it out for repair. Most major manufacturer's service centers won't fix it - they'll just replace the part. In the case of this socket on most laptops - this means replacing the motherboard. And that's very expensive unless it's under a warranty of some sort.

k well the problem now isn't that my comp won't respond to the outlet power, now it's just that the screen never turns on even though everything else is on. i took out the battery and plugged it in and it worked just fine, but the screen just stayed black.

Looking at the screen from an extreme angle can you see a faint screen image? The backlight and/or the inverter is bad

Another thing to try is to connect the laptop to an external monitor. Usually there's a plug on the side/back of the laptop that will allow you to plug in a standard monitor. Once it's plugged in, you may have to press the "Fn" button along with one of the "F" function keys along the top of the keyboard (on most systems it's got a picture of a monitor or two on the key).
