There is a disk floating about ATT I think its called. Boot to that and it checks all the sensors.

thats seems bad gpu KTM , specially macs are week in that behaviour , usually once gpu start to fail all internally start to fade out as well , the best option you got here is to replace the gpu KTM , also make sure you insert same chip , if its 128 bit USE 128bits , or you might have future issues

what KTM means ?

i make reballing to chip , and the same problem . you belive that i need to change gpu ?

Re: Apple Macbook pro A1286, wery slow

yes , indeed gpu chip can slow down your system once they are in life end . macs are expert on thaat issue , gpu replacement solve in the moment this issue !

Re: Apple Macbook pro A1286, wery slow

im mad, becase before reflow, or reballing, the fan works normal.
or how can i modify to run only processor graphics ?

Re: Apple Macbook pro A1286, wery slow

fan is controlled by smc. have u done a pram reset after reflow or gpu reballing ?

when a pc is slowind down generally it's intel chipset. (had an hp notebook that was slowing down and after a day it went dead. after reballing these small intel bga it went back ok to normal.
