Deployed soldier needs help! Why wont the laptop charge?

I am deployed to the desert right now and am having a problem with an HP Pavillion Zv5000. It simply will not charge the batteries reliably or run on the AC adapter. When charging the battery (while laptop is off) the power icon will stay lit for a few seconds then stop charging and go off. The Laptop cannot be run on the AC adapter alone like my Dell laptop. We tried replacing the adapter (used to have an aftermarket universal) with the original for this computer, and the battery has been replaced as well with no luck. The AC power source is a reliable 220v plug, which the AC adapter is well capable of handling. Is it possible that the internal connections from the adapter plug to the laptops power managment system is damaged? HELP ME RESOLVE THIS!!!
