Quoted from Guzz4851:
It could be a dead battery button cell on the MPU. There is a way to jump start it But I’m not sure what pins they are though. Before you tear into caps etc I’d start simple with the cheap battery.
I've read in several places about this "jump start" or "forcing the board to boot", but no one ever posts that direct information. This would be extremely helpful to many people (my self included of course).
If anyone knows how to do this PLEASE post or PM me with the info. I have 3 maxx boards that could use this help. Replaced the battery, power supply voltage is good (even tried a brand new one, changed ram, re-seated cpu, cleaned connectors.... nothing. Monitor powers up, hard drive fires up, bill receptor cycles, but there is no power up beep, which I believe could be an issue with the bios, possibly from a previous dead battery? This jump start/forcing the board to boot sounds like the last resort before you call a board dead and buy a used working one. I'm not sure of the Force, but I know the Maxx are linix based pc. There has got to be some info on how to get these going again.
Strange thing is that I have one machine and 3 boards. At one time all 3 were working, and now none of them work at all. Same issue with all boards after certain amount of time with no play?
