![]() I think you will find a very similar schematic at this thread on bad caps
http://www.badcaps.net/forum/showthread.php?t=41846 The PT stand for Potomac in your PT10F number. The above thread has a AMD processor same manufacturer of the C50 Processor in your Satellite. |

![]() Sorry about that. It is just every search in Europe came back at PT10 equaling Potomac. So does this have a intel processor or an AMD processor or does it not matter?

![]() Well i got a weird issue with this one , and its not a bios issue since i tryed several for this board and none didn't work .
it does start , but no image , i got a overall consume of 0.7 amp , and this unit its a UMA only PCH , when cheking coils on S0 all of them are powered excepting one phase of the cpu . but the most strange thing , is that once i insert dc jack machine does start alone (like no cmos bat on it or bios problem) but all seems correct and ok here , but machine simples start once i insert dc jack and no image at all . opinions guys . |
