Hi and many thanks for your help! Unfortunately the design of the Dim. 8200 is a bit weird. The small circuitboard with the power switch is connected to another small circuitboard, at the bottom of the front panel, which has 2 USB ports. These two circuitboards are connected by a strip with 15 pins (!) so I'm not sure which pins to connect, and I'm scared that connecting the wrong ones will fry everything.
Then, that circuitboard with the 2 USB ports is connected to the motherboard by a cable, and I'm not sure it can be unplugged from the motherboard. I pulled pretty hard, but didn't want to rip it out. It didn't seem like it would unplug.
It's strange how the power button is routed through that extra board instead of straight to the motherboard, but that's how it is. Any ideas? Thanks!
