On the systems that are not displaying APC UPS in the device manager, disconnect the USB cable and reconnect. The OS should re-discover the device. If the APC UPS device is not re-added, or HID UPS Battery is not added, check to see if American Power Conversion USB UPS is listed under Human Interface Devices. American Power Conversion USB UPS requires these drivers' hidclass.sys, hidparse.sys, hidusb.sys they will be found in C:\Windows\System32\drivers
If those drivers are there and APC UPS or HID UPS Battery is not displayed in the Device Manager under Batteries, I suggest rebooting the system.
If APC UPS is displayed after reconnecting the USB cable and communication is not established with the UPS, I suggest you resent the comm interface on the UPS.
To reset the comm interface of SMT, SMTL, or SMX model UPS from the display interface, hold the UP and DOWN buttons simultaneously for 5 – 10 seconds. The display flashes to indicate that the network interface has restarted.
To reset the network interface of an SMC model UPS from the display interface, hold the MUTE and MENU buttons simultaneously for 5 – 10 seconds. The display flashes to indicate that the network interface has restarted.
