Alright my laptop is having some trouble with battery + charging. When I turn on my computer without it being plugged in, it works fine. However when it is plugged in, the plug must be in a certain way, or else my computer will make a high pitched squealing sound and then turn off. This gets really frustrating, as if I want to charge it, it has to be standing on its back end against a wall, to make matters more annoying, my mouse cursor moves to the right of the screen constantly, making it impossible to play any mouse based games, or draw (laptop is used for Media Arts class). If this adds onto the ability to figure out the problem, I have banged my laptop a few times, and there are a few small cracks along the back.

A friend of mine suggested replacing the power cord, but I am unsatisfied with that solution because it does not provide an explanation as to why it makes the squealing sound. My best guess from where the squealing sound is coming from is the cooling fan.

Test the power supply with a multimeter. The voltage and amps are usually specified on the back of the power supply.

If it checks out OK - then it's likely a problem with the plug inside the case. That's an expensive repair unless you do it yourself (a friend recently did it on his laptop for about $50 - but he's very skilled at soldering).
