On startup, the computer performs a battery check by examining the remaining capacity of the battery, the capacity of the secondary battery (if one is installed), and other potential battery issues. If the system detects that the storage capacity of the battery is very low, it displays a 601 or 60X error message.
The message is displayed for 15 seconds before the startup process continues.
601: If Primary (internal) Battery (601) is displayed in the alert message, the measured storage capacity of the primary (internal) battery is less than 25% of the original storage capacity. The number “601” denotes the associated error code that is recorded in the system log. This error might be caused by environment factors like low ambient operating temperature, or by the aging of the battery pack. Operating your system in a warmer location for a while might resolve the condition.
602: If Secondary (external) Battery (602) is displayed in the alert message, the measured storage capacity of the secondary (external) battery is less than 25% of the original storage capacity. The number “602” denotes the associated error code that is recorded in the system log.
603: Battery not present: The test did not detect the primary battery.
604: Battery Charge Level Error: The test cannot determine the correct charge level of the primary battery.
605: AC Adapter Error: The test indicates that the battery is not receiving a charge.
605: Battery Counterfeit Check Error: A third-party battery was detected. If you purchased the battery from a reseller, contact HP.
607: Primary (internal) battery is weak with low temperature.
608: Secondary (internal) battery is weak with low temperature.
To resolve a battery alert message, update the BIOS and then perform the Battery Test in HP PC Hardware Diagnostics UEFI.
Download and install a BIOS update from the HP website.
HP recommends fully charging the battery before performing a battery test before Windows starts.
