DSDT Issues, second opinion needed.

Hi all,

I've been having issues with my laptop suspending, hibernate works fine but suspend results in a black screen, keyboard not working, and I have to do a hard shutdown.

I stumbled upon this: https://cannibalcandy.wordpress.com/201 … acpi-woes/ and I was able to finally get my DSDT file cleaned up. However I was wondering if I could get a second opinion on the results to see if I did the fixes correctly.

The BIOS for this laptop is on 9A-30B and has 4GB of RAM if this matters. I just realized I can't upload attachments, this is a list of changes I have done to the dsdt file:

I hope this is in the right forum. The dsdt is part of acpi spec and is a low level program, correct? I also still need to troubleshoot this issue: "ACPI: No _BQC method, cannot determine initial brightness" from my dmesg output. Perhaps this could be contributing to my problems from my previous thread https://bbs.archlinux.org/viewtopic.php?id=193538

Thanks in advance,
