I'm getting a hardware error and while I'm not a betting man, I'd almost bet the problem is the internal battery as it no longer holds any type of charge at all. Going through the process to clear an error, when I apply power to the machine everything appears to function normally for a minute or so and then I get the error. I can't run a Battery Test because it has to be running on battery before you can test it according to the service manual. Unfortunately I've never worked on one of these before and I don't see anything in the service manual about replacing it and being honest, can't see how to open it up.
Any info appreciated RE: Puritan Bennett - Achieva PSO2
