Just upgraded the bios on acer aspire to 2.03 (problems on brightness adjustment still exist - must be linux acpi related).
Searching the Internet what's with 2.03, I found this acpi tables (attached) for the acer aspire 4736z.

I hope this will help solve some problems on this model related to acpi. This maybe a minor problem on adjusting screen brightness but this will surely help extend battery life on this hardware when working properly.

For those who want to update their bios, here's the link for the latest bios for acer aspire 4736Z, version 2.03 as of this time of writing:
