IBM-OP500 Battery back-up

I have a IBM-OP-500 part #10K1911. Which has served me very well  The other day I rearranged some of my computer accessories, and then noticed the yellow LED lite was blinking. I took it to a battery replacement shop, but this battery checked out fine. In order to be sure we replaced it with a new one, with the same results. No matter what I do the yellow LED keeps blinking. I downloaded the manual, and could not cure this problem What can I do? Thanks Robert Colby

Re: IBM-OP500 Battery back-up

Have you tried pressing and holding the off\on switch to make sure it toggles to "normal" rather than "charge"?

Powered from a generator the APC 3000 UPS running on AC power and running on battery lights come on alternately

It is possible that the auto power detect section has gone faulty and is switching in this shunting manner because of an error in the line detect section. The op amp is detecting a low voltage to switch on and doing so it goes back to power. This can be due to a frequency problem in the AC generator and so If you switch off the generator the fault must stop.
If so have the generator checked for frequency change or the UPS has a circuit error. Try to set the AC voltage of the generator up to the required level if there is a drop on load.

It may still be supplying power but the surge arrestors were probably damaged by the surge. Go to choose support from the menu bar, they should be able to help or maybe even replace your unit.

IBM OP500 Uninterruptable Power Supply that is the link to the manual you need. It sounds like your UPS is not turned on correctly. You must press and hold the on switch. Make sure the AC sign wave is lit solid not blinking, the battery should not be lit as well. If the battery is yellow, that means you are running on battery, if it is red that means the battery is low.
