HP EliteBook 840 blue screening after being encrypted?

Question

We have started rolling out Safeguard to the laptops in our facility and have been getting calls of machines blue screening after we encrypted them. So far the only common factor has been that they are HP EliteBook 840 models. Is here a know issue with these models that would be causing them to blue screen, or is there some proprietary software from HP that can cause this? They are all Windows 7 Professional 64bit.

Hi Jacob, 
 
We do get numerous reports of issues on these machines, but they should be fine if all the requirements are met for encryption. Can you confirm if these machines were defragged and put through a chkdsk C: /F /V /X? 
Do you know if these machines have the HP Drive Encryption application installed? This will cause conflicts when installing an additional encryption application such as SafeGuard. 
 
Typically the bluescreen details will show something like: 
UNEXPECTED_KERNEL_MODE_TRAP (7f)

BUGCHECK_STR: 0x7f_8 
DEFAULT_BUCKET_ID: WIN7_DRIVER_FAULT 
 
If that doesn't help please upload a screenshot of installed applications on one of these machines and I'll see if there's anything that looks suspect, like Intel RST / RapidStart.
