Vista desktop doesn't power off after shutdown

[ncanqn]

Hi everyone,

I have just experienced the following problem with my desktop.

- Windows XP + AHCI mode (Intel port, yellow) ==> Shutdown + Power off successful

- Vista Home Premium 32bit + AHCI mode (Intel, yellow port) => Shutdown but not Power off

- Vista Home Premium 32bit + AHCI mode (JMicron, purple port) => Shutdown + Power off successful

- Vista Home Premium 32bit + IDE mode => Shutdown + Power off successful

As you seen, using AHCI mode with purple port is fine but if I plug the second HDD into the second purple port, this HDD will appear as USB HDD in windows. Therefore, I want to use the yellow port which is Intel controller. Any suggestion to fix power off problem when using Intel SATA controller?

Thanks.

My specification:

CPU: Pentium D 3.2

Main: Giga P35-DS3

Graphic: NVIDIA 7100S

HDD: Seagate 250

I tried to plug on any yellow SATA port, but still the same problem. Please help me.

Thanks

Did you try the latest BIOS update?

Thank you for replying,

I'm now using the lastest BIOS version even beta version F14c. I also tried with F13, the result is still the same.

I noticed that either BIOS version F13 or F14c, the AHCI BIOS version is the same and old, i think.

This is the message that is displayed on my screen: "Serial ATA AHCI BIOS version iSrc 1.07 08042006"

So, probably Gigabyte has not been updated the intel AHCI on their updated BIOS.

Any idea?

Thanks.
