After BIOS update all was well for 15hours only!

Yesterday, after updating the BIOS I tested power connect/disconnect recognition in both Windows and Ubuntu 12.04 and suspend on lid closure. Everything worked fine. Then, in Ubuntu 12.04, I suspended the system over night. Next morning, lid closurefails to be recognised by Ubuntu. Power connect/disconnect fails to be acted upon properly by Ubuntu. In Windows, lid closure still fails but power connect/disconnect still recognised - but it takes several seconds rather than being almost instantaneous when all was well the night before.

Very infuriating!... is this Ubuntu corrupting things in the BIOS or is the BIOS somehow corrupting itself with respect to ACPI.
