Lenovo B / G Series :: G570 - Battery Not Getting Power From Charger At All

I've looked at the other threads and tried removing the battery while the laptop is off for 30-40 seconds but it doesn't run because it's not getting power from the charger at all.

The laptop is a couple years old and the hinges on both sides have been pried off (can provide pics) but I never had problems until now - I plug the charger in but it won't charge and even if I pop the battery out it STILL doesn't charge!

One night, I had to set the charger upright in order for it to charge. Today I had to set the bulky and heavy part of the charger higher above the laptop in order for it to charge. Now, how to get this thing to work because proping the charger upright or higher than the laptop isn't working anymore!

I've noticed a couple weeks ago when I was visiting my parents that the adapter emits a beeping sound - notice that I said the adapter NOT the laptop. If I unplug it the beeping sound fades. The beeping sound comes from the adapter and when I unplug the cord going from my laptop to the adapter you can hear the beeping sound fade away from the prongs that conect the adapter to the laptop (not the prongs that plug into the outlet).

Like I said before it doesn't matter if I've plugged it into an outlet with OR without the battery in it, the laptop does not receive any power from the adapter or recharges.
