Brendan,

You are brilliant.
I downgraded one of our AO753’s from V1.24 to V1.16 and it works.
The Acer Aspire 1830 is also an identical BIOS so the downgrade worked for them too (From V1.20 to V1.16).

Tom, Not sure if any of this can help? But have amended the descriptions of each bios version below from the Acer website.

Version - Description
1.24 - BIOS (Well this isn’t much of a description)
1.20 - Releases for support WiMAX
1.16 - 1. Updates ROM to support LAN chip rev. B.

Updates ME version to 6.0.42.1221.
1.11 - Solves no display issue from S3 resume during OOBE at the first cycle of factory default preload.

The zip files don’t appear to have an release notes or change logs.

Regards,
Jason
