[kwlug-disc] HP t630 power supply

[Anton Avramov]

Thank you Ron,

I don't mind butchering, but the information online is that those HP 
power supply are using 3 connectors having a resistor on the third 
middle one. Based on the resistance the device knows how much power it 
can draw and if it doesn't have a power supply with the right resistor 
it would refuse to power up at all.

I don't have the connector, but If I can not find an original power 
supply to test I'll take you on your offer and solder the power and the 
resistor directly on the board and see what happens :)

I'll wait a little bit more and let you know.

Thank you once again :)

Cheers.
