At this stage, the support for your product is offered through your computer manufacturer. I recommend checking the link below for troubleshooting assistance on your Sony computer:
I know for partition information for 8 GB, the value should be 8000, please take a look at this URL for more details:
I am afraid Sony support is being very unhelpful and failing to supply this information. Are you able to give me generic information about the normal requirements for the Intel chipset on this system? For example, can you tell me whether the 8000 Mb partition needs to be at the extreme end of the disk? Also, since this motherboard uses UEFI boot, wouldn't this manual be more accurate?
Perhaps you could at least tell me which chip model number is the one responsible for the rapid start feature, in the above attached system report, so I can look for information based on other's experience with the chip?
