We use AOC-USAS2LP-H8IR without battery. When we boot up system, we got error message “…that are configured for write back are temporarily running in write through mode. This is caused by the battery being charged, missing or bad. Please allow the battery to charge for 24 hours before evaluating the battery for replacement. Battery status: Not present”. We would like to know can we use AOC-USAS2LP-H8IR without battery. Why we got the error message? Any impact and how to avoid?
The error message is just a warning only. It does not have any performance impact.
