Power the machine on while holding the Up, Right, and Down buttons at the same time. The machine will boot in service mode. Once it boots, scroll down through the menu until you find, "Check 8: Parameter" and hit enter. Then scroll down to, "Parameter2 : Update' and hit enter. Then scroll down to "Update6: Charge FLG" and hit enter. Then change this parameter to, "User/Init: Charge" and hit enter. It will save and then you can power off and then back on again and it should boot like normal.
