Question Broken PicoPSU - - constant 12V ?

[SandwichMaster]

So, I have a broken PicoPSU - the 12V rail (which should just be a pass-through from the external AC-DC convertor) isn't giving a voltage. I've fixed this by bridging across from the 12V input, to the 12V on the output side. All the other voltages are OK. This works fine, except, I can't put my computer into standby - probably because the 12V rail is now always on.

Question 1 - would a permanently live 12V prevent the PC from going to standby?

Question 2 - if this is the problem, any tips on fixing a picoPSU?

Bridgning might cause issues. Your external power brick' voltage can and will fluctuate, depending on the load.

As for "fixing" - you have to "follow the yellow path", and see where 12VDC rail is broken. I doublt you'll find a schematic for your PSU, so a good set of eyes, a voltmeter, a scope, and understanding how the electrons flow are needed.

Yeah you're right about a schematic - I've spent ages looking for one with no luck! The external voltage is pretty steady at 12.3V - from what I've read the picoPSU just passes that through anyway.
The kernel log shows that it's the ssd bringing it out of standby, so if I can find a way to stop that it might be ok. I'm better with software than hardware so I might try that first
