I have a GX280 board with HS/F but no Dell case. I see that the FP connector is propietry. I have tried shorting varies pins with a screwdriver but nothing, i have shorted many non-dell board to find the power on pins and have never had a problem, i.e damaged the board. But still i couldn't find the combo to short it to power it up. It has 2 rows of 17 pins and one pin missing. From what i have googled the pinout is undocumented and nobody knows the combos individually.
Surely i can't but stuck here, any ideas how i can figure out the pins to short to power up the board?
HOLD ON i just found a diagram on this page, http://scarvell.net/wiki/index.php?title=Dell_PC_FRONT_PANEL_PINOUTS
from what i can make out it could be pins 2,3 and 4, any thoughts?
Sorry, no thoughts, other than try the pinouts.

The GX280 DOES NOT USE the Dell_PC_FRONT_PANEL_PINOUTS described in that web page.
That WEB page has pinouts for VERY OLD pentium 3 based OEM INTEL motherboards.
The Front Panel on a GX280 is attached to a front panel board and ribbon cable that is totally different from that kind
of front panel found on an SE440BX INTEL OEM motherboard.
Its not possible to Guess such things. You didn't say which model you have.
The on/off button goes from the one ribbon to another ribbon to another board to another ribbon to the motherboard.
The Grey cable below plugs from the front cover to the I/O board with the USB ports then another ribbon goes from that board to the motherboard.
