    Hello,

    I have an Acer 5720G. Recently I bought two 2GB's of RAM and along with it upgraded to 64 bit Win7. I started getting the blue screen of death on boot (right after the windows logo first shows up) with the message "Your BIOS is not acpi compliant". When I downgrade to 3GB's of RAM employing the original 1GB chip, the problem resolves. Both 2GB chips memtest error-free, and the crunchbang linux I have on a separate partition runs fine on 4GBs of RAM, so I suppose this is just capriciousness on windows' part. I googled the situation and saw that people resolved this with a BIOS upgrade, so I believe this constitutes just motivation to mess with the BIOS. Not having done this before, I was cautious and decided to do some homework, and saw all those stories of Acer owners bricking their notebooks doing just what they're told by Acer, so I'm very hesitant to go ahead with it. Acer provides an upgrade here:
    Acer Support: Downloads & Support Documents - Notebook / Aspire / Aspire 5720G

    Should I go ahead with it? What's the current situation on this (most bricking stories were at least two years old)?

    Any do's, don'ts, warnings and advice would be much appreciated.

    Thank you.

    "Your BIOS is not acpi compliant" means a DSDT bug. If the official v1.45 doesn't fix it, then it will be fixed in v1.45 MXM Edition V2. (Unfortunately Acer is not planning to release v1.46; so it can be only done in a 3rd-party mod, like MXM Edition.)

    BTW, the best way to update a 5720G is using the Fn+Esc method: burn the BIOS image (renamed to ICL50HW.FD) to a CD, then remove the battery & AC, and holding Fn+Esc, plug the AC back in and press Power. This can also be used to recover from a failed flash.

    The download from the Acer support site is an .exe, how can I get a hold of the BIOS image to do it the way you recommend?

    Also, where can I find the MXM Edition if necessary?

    You can extract the .exe using 7-Zip to get the included .fd file.

    MXM Edition V1 is in the 5920G vs. 9600M GT thread. V2 is not released yet - I'm still working on getting it fully right.
