My FW800 had a broken CPU. The guy who owned it before soldered there something and after that it booted until the apple logo and hanged after that. Now i got a new cpu from a MDD (both are 1,25Ghz CPU's). I installed it but it didnt turn on. The computer started, but after a while the case fan started to blow very fast and nothin else hapend. I removed the CPU and noticed that one pin was a bit moved sideways( i'm not sure if it short-circuated something, could be possible). I bend it straight again and installed the CPU back. Still the same problem.
Somehow i noticed the PMU switch, while the computer was running i pressed it. Still nothing. I'm pretty sure i pressed it twice after the computer shut down. Still the same. Also noticed that the power button lights up for a second when i press it, the computer starts but the light goes off. So i did the PMU reset the way it was ment to be. Removed the power cable and the battery and pressed it once. Still the same problem.
I tried my old CPU but the same hapend with that.
So what would you guess, did i brick mu motherboard, and possibly my new CPU too? What should i do and how can i be sure what works and what not.
Oh and i measured the voltage of the battery, it was under 1V.
Just in case, my old CPU had a sticker on it:KC3090HKP6SA* SINGAPORE MPU 1.25 GHZ DP
My new one has:J53325NGPXAA* 630T4800/630-4799 CN MPU 1.25GHZ
