ACER ASPIRE 7520 NO CHARGING, NO RUN ON MAIN, RUN ON BATERY ONLY

You cannot visually inspect laptop components to verify component level damage. You may have damages something in the motherboard tracers, or popped a solder loose, or worse, created a micro fracture in one of the surface mounted chips.

Before going further, i would suggest you thoroughly test the battery, or power supply for charging the laptop, as well as make sure the power connector jack on the motherboard is not damaged in any way. If the jack is the problem, they are quite easy to replace, but knowledge with soldering on delicate components may be necessary.

I would have suggested requesting an RMA if the laptop was still under warranty, but by removing the motherboard to inspect it, you have voided any warranty you may have had.
