Recently I upgraded my Asus N550JK with a 512GB SSD, MX100 from Crucial, and replaced my DVD drive with the old hard drive. I successfully wiped the 1tb hard drive I had in before and installed Windows 8.1 64-bit onto the SSD. Almost everything is working
as intended.
When I opened task manager, I notice an odd thing, my cpu usage was higher when my computer was doing nothing at all. (seen here: http://i.imgur.com/bav1ACJ.png )
After doing some research I began using two tools to uncover the problem. The first of which, LatencyMon, told me that the ACPI.sys driver was causing issues. This is what I see:

I have also used the "Windows Performance Analyzer" developed my Microsoft, and found similar results:

I have updated my bios to version 208 and updated my chipset drivers to the latest version. I reinstalled the ATKAPCI package for the model N550JK and have had no luck.
I've contacted support many times and they cannot figure out what is wrong. I am slightly frustrated because my laptop only lasts for an hour on battery life due to this issue.
I can send you the .etl file if necessary, but I want to solve this issue. Research I've done indicates owners of computers with SSD's are more likely to have this issue, and it is surprisingly common in laptops.
Other people have suggested on various forums to rollback the bios to an earlier version of Asus Bios, I believe it was 205, but I can't and won't download from a random source.
Disabling various devices in the device manager does not seem to fix anything either. I believe there is a bug in the code.
