Thanks much for all the good comments. Gave me some stuff to think about. I’m reasonably sure the battery is OK, as if I unplug the thing, the computer will run OK. I haven’t done a full powerfail test on it recently, but might just do that tonight to validate the battery.
I have one that is about a year older that I have hooked up to my media player and stereo, and it doesn’t drop like this one. I have noticed a =very= slight blip in music playback when power drops on my desktop one, so it does seem like =something= is going on with my house power.
Using the ‘pwrstat’ tool from Cyberpower to query it, I see the following.
The UPS information shows as following:
Properties:
Model Name................... LX1500GU
Firmware Number.............. BF014xxx
Rating Voltage............... 120 V
Rating Power................. 900 Watt(1500 VA)
Current UPS status:
State........................ Normal
Power Supply by.............. Utility Power
Utility Voltage.............. 122 V
Output Voltage............... 122 V
Battery Capacity............. 100 %
Remaining Runtime............ 94 min.
Load......................... 72 Watt(8 %)
Line Interaction............. None
Test Result.................. Unknown
Last Power Event............. None
Unfortunately, Looking at the configs for ‘pwrstat’ there doesn’t seem to be an option for its sensitivity.
I’m going to try to see if opening a TT to Cyberpower does any good, and will try running a self-test tonight as well.
Again, thanks all. Hopefully I won’t have to buy a new one.
If you have an older home, try pulling the MAIN FUSE or BREAKER, for the entire house, at the meter box.
Then remove the front panel to your home’s electrical fuse/breaker Box and TIGHTEN ALL THE SCREW CONNECTIONS WITH AINSULATED SCREWDRIVER. Replace cover and reinstall fuse/breaker.
The connections can loosen over time and cause intermittent electrical spikes. This comes from heating/cooling the connections as they are passing current that builds up resistance and thus heat and eventually fails.........................
These are mostly lead acid batteries
Don’t expect much past 3 years.
