The issue could be due to completely drained batteries or improper battery installation. If the battery voltage drops below 4.8V, the system will alert with “Low battery, replace battery.” If not replaced, the batteries may fully discharge, causing no power to the motherboard and no display. Also, mixing old and new batteries or different battery types can cause power supply issues.
