Oh ffs, what a noob I am !
Plugged in an 85w mag and of course the fan starts to spin, also just noticed while trying this again back in the mac adding one cable at a time that no matter what is connected and regardless of running on magsafe or battery when you turn it off by holding the power button after a couple of seconds it seems to power itself on again and the fan starts spinning and keeps spinning until I hold the power button down and disconnect the battery and the magsafe.
OK removed U1950 noticed that C1950 looked slightly corroded and it looked like a break in the trace , Removed C1950 and made sure I had repaired the trace getting 3v to pin 8,
I got 3V at pin 2/U1950 now,
But... I have blown U3560 into the abyss! ( How important is this? ) can I work without it or is this another board for parts bin?
I also just noticed that since cleaning up U1950 I no longer get a constant fan spin but what seems to be power cycling , on for a few seconds then off for a few then back on again etc etc same for both voltages and fan spins .
Power cycling seems to have stopped or only happens after long periods of being turned on when testing voltages,
I'm currently in the process of ordering a Medusa ( And a pile of Tiresias (the GPUkiller) chips ) from Harald but he is currently on vacation until the 23rd of june
Without a Medusa would I need to remove the bios chip to try good bios? Or am I best of waiting till the Medusa arrives?
( Also I notice there are 3 different versions of the Medusa what version would you recommend I get?
I don't know if Harald has newer version than 3, for Medusa.
I got version 2 long time ago and still does the things I need.
Probably is better to get version 3, or which one is latest.
Be sure to get all necessary adapters, to connect all kind of boards and single chips.
He has in stock some board adapters with 1.8V support.
I'm still pending to test his battery port tester, received few weeks ago.
Is not dificult to flash SPI chip outside of the board, using cheapest CH4341, or other programmer.
Spoken to Harald, I have to wait until he is back from vacation ( 23rd) before I can put an order in so going to try removing bios chip and using my cheap programmer.
I've just tyred searching the board for a clean ME bios for this board but don't see one posted recently. Would you have a good bios file I could try please?
Also could you give us your feedback on the battery port tester when you have had a chance to try it out.
