There is no way to externally charge the battery.  That said, does the system recognize the AC adapter (check in setup - F2 at powerup)?  If the adapter shows unknown, the battery will not charge (nor will the system run at full speed. If the adapter is unrecognized, try a new OEM Dell adapter first -- if it is also not recognized, replace the jack: [URL] If neither of those solves the problem, replace the system board. Note:  the AC adapter will power the system even if unrecognized though not at full speed.  However, an unrecognized adapter means the battery will not charge.
