Sony VGN-FZ19VN schematic needed

[Scootie]

Hi there,
I'm looking for schematic for the machine above. The laptop starts up, shows logo, reaches the boot from hdd but then shutsdown. When I try to reboot it the power led blinks twice and that's it. If I remove the AC I can do this all over again.

Hello,

I guess the mainboard is mbx-165 right?




My first guess for this series is the gpu chipset.

Yes, idd, I forgot to mention that. Im trying to find out why isnt the cooler spinning up on start(at all), this must be the cause why the laptop turns off after 20-30 seconds. I tested the cooler and it's working, problem must be somewhere else on the mb.

Fan doesn't spin at start always on those series. If you can do a light reflow on the gpu.

This model doesnt have a gpu, only standard intel sb/nb.

Sorry my mistake. I would start from the cpu as you describe it.
