Hello,

I recently had an issue with my Inspiron 15 7579 which culminated in the LED diagnostic indicators flashing that I had invalid memory installed. I reseated the memory and that seems to have solved the issues I was having with performance, but after this fix I was being prompted for my BitLocker Recovery key at every startup.

I followed the steps at this link to no avail: https://www.dell.com/support/article/en-us/sln304584/bitlocker-asks-for-a-recovery-key-every-boot-on-usb-c-thunderbolt-systems-when-docked-or-undocked?lang=en (with the caveat that I could not find any setting to "Disable USB Type-C or Thunderbolt 3 (and PCIe behind TBT) Pre-boot" in my BIOS menu).

I finally ended up suspending my encryption by typing "manage-bde -protectors -disable c:" in my command prompt as an administrator. I intended to enable the protectors again but when I run that command I get an error that no TPM is found on my device, which makes sense as Inspiron's don't have one. However, now I'm stuck with my encryption suspended and can't figure out how to resume it. 

Any help is appreciated! Thanks!
