Question about Compaq UPS R3000 (242705-001) UPS System
I recently came across one of these units and the batteries have been dead for a while and need replacement. The problem is the ups had no power to it for a year or so and when I plug it in it doesn't power up when I push the power button. I'm a electronics technician and I put it on my bench and the standby power circuit seems to be working, but I noticed two eprom chips in the unit, is it possible that the software was erased over that time from not having power. I have the parts to replace the other chips on the board, but I don't want to put the time or money into it if the eporm memory is gone, or is there a way i can upload it from the serial connection. If possible, can I buy a whole new power board?
I have repaired the same.
there are some dycon to protec the circuit in the bottom part of ups that sometimes are broken,
sometimes one plug of the battery is disconnected.
can you give me the software to make shutdown of xp pc when we lost power?
