My 4005 is stuck in a continuous boot loop. I need help restoring it back. I am not going to replace the mother board as they are very expensive. I need help
What caused it to start doing this? Did it crash and then start looping when you tried to warm/cold start?

Power it down. Disconnect the battery. Wait about ten minutes and power it back up. AC first.

I’ve had to do this more than once on a 4100U/ES stuck in a boot loop, while also disconnecting the RAM battery. (done by just sliding a piece of card stock or something between the battery and the connector. Those clips can break, so best not to bend it if possible.)
But in fairness I don’t know if that would cause a 4005 to lose its program… It doesn’t on a 4100ES, but I’ve seen other systems that do.
I was programming it when I went to save the config it wouldn’t start back up. I’ve tried everything I could
Could it be that I added cards to the expansion power supply slots when I don’t have an expansion power supply?
Thats probably it. You might need to buy a new CPU.
It’s been a while since I’ve banged on a 4005, but if I remember correctly it has 5 i/o card slots (for NACs, IDCs, relays etc) on each side of the main board, and if there’s an expansion power supply mounts separately to the chassis and plugs in via a connector on the main board.
In any case, if you have expansion cards installed it might be worth removing them and then trying to boot, in case something is confusing the system. You’d get card errors if it should start up, but If it boots then you could add cards 1 by 1 to see if one of them is causing the problem. (powering down each time of course.)
What I mean is that I programmed cards which I don’t have to the expansion power supply or any cards for it.
Why the hell would you do that? It’s probably stuck searching for those cards
