Before opening I would check the power adapter. Can you locate a second power adapter to try out? Or access to a second system (Asus X53E) to try your power adapter on? Is the connectors clean and not damaged (adapter & system)? If they are dirty unplug the adapter then with a cotton swab (Q-Tip) with some Isopropyl alcohol wipe the contacts. Any better?
