I need help identifying this components, first marking MPAG apparently from MPS but I cannot find any with that marking. The other one ES=CL supposedly richtek?? I find no info for both. Laptop is DELL precision m6600, video card have no voltage rails at all, one time I got image but never more, measured 19v 5vrun 3vrun are present in graphic card, gpupwren signal also. I guess the first chip MPAG can be related to some voltage prior to gpu core rails. Any help will be appreciated. Thanks in advance

Thanks mate, I checked and datasheet matches chips pinout, I know now power rails they feed. I've been trying to find any info about this old video chip Nvidia Quadro, but I don't find anything, is there any info available?? At least voltages distribution or any schematics or boardview for reference purposes only.Originally posted by piernov View Post

By any chance u have any idea what component is this, it looks like a transistor sot23-6 marking 3013, but I don't find any logical datasheet that could match and the measurements are weird (I measured one out), it looks like double transistors for enable purposes, there is a whole network of this components connected, I took the first one out and forced enable for rt9018 and I got 3.3v and 1.05v from mp28275 but still no GPU voltage or vram, I guess there is a sequence problem but no schematics and I'm trying to understand the logic for this but I'm stucked 😔Originally posted by piernov View PostComment
