sony vaio sve151e11m

[ozy]

Working on this laptop that had water spilt on it, and was completely dead,
Replaced pu102 (tps51427a) and removed pq269(SSM3K09FU) VA_off mosfet (awaiting replacement, but removed for now to enable VA)

The laptop now powers up but will not recognize any HDD, or boot from optical drive although they do both spin up, in bios HDD shows as none.

If I boot from usb windows install does not see any drive.

I have 5v at both optical and hdd sata ports, but have never really done any work on sata port so not sure where to look.

this uses the Quanta HK5 DA0HK5MB6F0 MBX-269 motherboard
I have attached schematic for it in case anybody needs it.

Any help would be much appreciated.

Thank's for the schematics. Even if I have a problem. In practice, the computer start normally and after ten minutes the display will not show the images, and the pc was extinguished. Also by connecting to an external monitor gave the same problem, I made a reballing the gpu and worked again for half an hour. After which it is turned off Since that day, if I turn it on, the PC is on but not from the video screen, either on its display, or if I connect it to the external environment.
It could be the ram around the video chip?
Thank's in advance
