Question about Compaq UPS R3000 (242705-001) UPS System

1 Answer

Compaq r3000 ups drops out while pluged in to a\c power

The ups will work fine indefinitely then for no apperent reason it will lose power on the output plugs and none of the LED's change, if you the cut the a\c power to the unit it will switch to backup and restore power. Then you can restore a/c power to it and it will run indefinitely again and repeat the cycle. The batteries are fresh and it only recently started doing this, it is as if there is some kind of circuit breaker,other than the ones on the back, inside the unit that is letting go prematurely. Only 1 LED is lit on the load bar so it should not be overloaded, I know for sure, from amp measurements, that it is only supplying 4 amps of power normally and 11.7 amps with everything possible on.
Thanks

Did you ever get a resolution to this issue? I have the exact same problem. Someone advised that I should ensure that the Sleep mode is disabled through the config but that is already the case. Do you by any chance have the UPS in a non-air conditioned room where it might be getting too hot? Secondly, do you have both the battery leads connected to the battery pack or just one of the pairs is connected?

Compaq Presario R3000 dim screen but not dark


Sounds like the auto-dim in the BIOS is set too low. Fortunately the Compaq R3000 allows you to adjust the brightness right from the keyboard. Hold down the [FN] function key while tapping the [F8] key will brighten the screen, while [FN]-[F7] will dim it. The settings are different for running on AC power and battery, so you must do each individually.

Power problem


All batteries lose their ability to store power after every recharge. I would say the problem is the battery so get a new battery soon but don't forget to charge the new battery. If the problem is still there after replacing the battery, then my next guess is the laptop.

Laptop won't stay on


it might as well be a internal problem related to power or loose contacts with RAM or the power chords internally.
Better to go to the technician in this case.
Your first Battery would have been fine too..

Less then 5 minutes runtime at minimal load


You gave no reasons why you thought it was simply a software setting, so I gave you a link below for some management software. The HP R3000 UPS supports HP Power Management Software (CPM) version 1.8. http://h18004.www1.hp.com/products/servers/proliantstorage/power-protection/software/legacy-software.html In addition the HP R3000 UPS also supports the LanSafe III management software (discontinued). My first question is: When were the batteries last changed? If they haven't been changed in 3 or so years, then it's probably low batteries, meaning they are old and cannot take a charge anymore.
