hi duke,

this is an old whore so its definitely fucked by others - I checked R5200 and R5201, diode mode 0.490, 3.33 to 3.40V when powered on. I also removed the flex from J3500 to no avail.

after 4-5 tries it stopped beeping and R5201/02 (SMBUS_MCP_0_DATA) reads 1,1V momentarily - same time the fans seems to pause for a few mseconds - like a restart (it doesn't chime so cant tell for sure).

couple of tries later the beeping is back.

fucker.

Yeah, probably fucked up MCP or something. I would know where I would put this board.....

 

[george-a]

yeah I suspect the MCP too... since I have the tools for an easy MCP swap I will give it a try and if that fails this board goes ..well you know where.

thanks a lot dude.
