UPS constantly reconnecting

Hi,

I have been experiencing this quite a few times:

Sometimes the UPS suddenly starts to disconnect and reconnect and I get notifications: https://goo.gl/ozMbyT

The only way to stop this is to turn off the machine and the UPS, then turn them on again.

I can’t find a pattern, it happens randomly. Sometimes it doesn’t happen for weeks, other times it may happen more than once in a day.

What is the reason for this behavior and how to make the connection stable?

I am uWhat is the reason for this behavior and how to make the connection stable?sing nut, the UPS is MGE Pulsar Ellipse Premium 1200VA.

/etc/ups/ups.conf


[myups]
        driver = usbhid-ups
        port = /dev/usb/hiddev2
        desc = "UPS:Pulsar Ellipse Premium"
        vendorid = 0463

journalctl -f shows:

How is the physical connection done? Try replacing the cable.


Cheers / Saludos,

I have no other cable. This UPS was bought many years ago with only one cable and it is a specific one.

But I believe the connection is ok. In Windows I am not getting any disconnections (using the MGE software).

Is the battery still good?? You know they don’t last forever

Yes. Replaced with new one about 2 months ago.
