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

Compaq R3000 (Doesn't power up)

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 the Compaq R3000h UPS. Has been stored for some years, batteries haven't been replaced. When mains power is connected it clicks about once per second and flashes various LEDs on the front panel.

r u mention for battery light?if is it true,then the light is blinking because of your laptop want to make sure the power supply charge that battery.if it is in charging condition,the light on.but if the light goes off,that mean, the battery is already full.

But when u use adaptor without battery, the light will goes off because no charging session is in progress which has same behaviour with battery full(during battery full,no charging session occur)

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


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?

My Compaq R3000 does not charge up


The problem might be the battery itself. Four years is a long time for rechargeables. Also, check if the error ocurs when the battery is not in the slot.

The power plug won't charge the battery which prevents the computer coming on


There was a recent class settlement agreed to by HP regarding these models. HP failed to notify a ton of its customers and I've contacted Scott Kamber regarding.. (We were consultants for the suit).. Weve repaired a ton of these and you are not alone. Did you buy the machine new and register w/HP? Just curious...

It probably needs a new DC jack.. There was a class settlement regarding these models but you are too late for a refund on repair. Weve replaced a couple thousand of these on this model.
