Pismo battery issue

Pismo tells me it has 0 hours on it. Completely drained.

Hi folks:

I have an odd battery issue going on here. I had send my Pismo off to get some work done on it. When I sent it out, the battery I had was generally carrying a charge for about an 1:30 or so. At some point during the work process, I was told that the battery was (suddenly, AFAIK) no longer holding a charge. I figured OK, I've had it for about three years, I hardly ever use it, maybe it was about time for it to die.

So, after all the work is done and I have the Pismo back, I get a new battery (well, a new refurbished battery). It shows up, I plug it in, and presto, a 3-hour+ battery is now mine for the using.

That was two weeks ago. For some reason today I decide to have a look at the state of my new battery . . . and Pismo tells me it has 0 hours on it. Completely drained. I already tried a reset--I'm told that can jolt a battery to life, but no dice. Regardless, to have this happen with two different batteries makes me wonder if the people who did work on my Pismo shorted out or cut something that should be working otherwise. So my question to you, campers, is what do you think might be going on here? Is there some piece of circuitry that you think might be a candidate for having been messed up? For the record, I got a new CPU card and a new logic board installed.

Thanks in advance for any thoughts.

Cheers, Carl

What the service manual recommends:

  1. Verify the battery is charged by pressing the level indicator button on the battery. If the battery is charged, one or more status lights on the battery will glow.

  2. Turn off the computer. Press the reset button on the back of the unit, wait five seconds, and press the power on key.

  3. Try battery in opposite expansion bay.

  4. Try known-good, firmly seated, charged battery. Try the same battery in opposite expansion bay.

  5. Replace power supply card.

  6. Replace I/O logic board.

[Power supply card is a likely contender. Can be found cheap on eBay]
