Sorry for bumping an old thread, hopefully someone is still watching. I have a slightly similar issue: I'm thinking of replacing an IT8720F on a Gigabyte desktop MB, but I'm not sure if it can be done directly, by simply putting in a blank chip in its place, that's why I'm asking.
This board's been lying around my shop for like 2 years, so I thought I'd have a look at it today (since I didn't have a matching CPU for it until now). It's acting really weird and I think it's the ITE chip to blame. I was finally able to get it to fire up, though it's still not working perfectly: you plug the PC in, it tries to power on for a second, then goes off. After a few more seconds, it tries to power up again, but again shuts off and stays off. The power button does absolutely nothing and there's only 0.6v on the button's pin (same on the reset pin). The way I was able to get it going was by briefly shorting some pins on the ITE chip, close to the corner, though I'm not sure what they are - probably some data line which causes the chip to reset or something. The first time I did this, the board fired up, told me the BIOS is corrupted and it's restoring it from the backup chip. When the process ended, the board restarted, but it came up with the same message and tried restoring the BIOS again and again until I cut its power. What I did next was replace the M_BIOS chip with a blank one and this time, after the recovery process, the PC booted into the BIOS setup menu. Still, it would not respond to the power/reset buttons at all...the only way to get it going after a shutdown was by doing the ITE trick again. No amount of clearing the CMOS gets it going: it just does those two power-up attempts then dies. While it's on, I even upgraded the BIOS to the latest version which worked, but the issue persists, so I don't know what could be causing it other than the ITE. Thank you.
