Re: Mini Lenovo PC Dead Power supply (ACbell PCH018)
You can simply power the PC with just a 12v supply (provided it can deliver enough current) and not bother with the green wire. It worked in my case. I assume if you have a normal ATX supply which requires turning on, you could short the green wire to GND permanently and use the 12v output to power the PC. This would also mean the fan on the PSU runs permanently !
Alternatively, you could probably connect the after-market ATX to the PC "the right way" and make use of the green wire too to switch it on/off, but I haven't tested this to confirm, because it doesn't make sense for this to work as long as there's no STBY voltage - there would be no way for the PC to control the PSU. I imagine what the green wire does is toggle the original PSU between a full power and a low power state to keep power consumption as small as possible, despite the output always being on and fixed at 12v...this makes more sense, since there's no other STBY wire.
