My 750AGP suddenly went out of order. It looks there is some trouble in the power part on the motherboard. If there is strain applied on Motherboard, I can measure 19V on 5A fuse (below CPU board) and book is running. But when I release the strain, book switches off and there is no power going into MB. Moreover the strain to be applied to make NB running must be higher and higher. I guess there will be only couple of parts before the fuse, and some of them is probably badly soldered and there is cold, non-cunducting connection. I checked the connector (resoldered it, for sure), but this was not the problem. Any hints regarding the scheme ?
Thanks a lot. Vlastislav
