You're welcome... If you search the web for that ME error, you'll find it's not an uncommon issue in various OEM PCs. Did you try disabling TPM in BIOS setup? Removing the battery and clearing BIOS does not violate the warranty. Follow the instructions in the Service Manual. If you don't want to do that, you could try a BIOS Recovery, which I linked above. The motherboard diagram for the XPS 8930 in the Service Manual doesn't list an ME reset jumper, but I presume it has one. There have been instances where that jumper was installed on the wrong pins at the factory in other Dell PC models, which caused these problems... Guess I was lucky not having this issue when I upgraded to BIOS 1.1.16 last week. But I always do them manually totally outside Windows via the F12 boot menu, so that might be the difference. And in the future, don't ever let SupportAssist manage BIOS updates for you. Even if they replace the motherboard, your warranty will cover that. Please post back and let us know what Tech Support does to solve this. The info could help other users who may run into this ME problem. 
I have a 9 month old DELL XPS 8930 running Windows 10 Home 64bit. A few days ago, Dell Assist prompted me to install updates (including BIOS 1.1.16). Upon restarting, I received the following 2 errors: (A7) Me FW Downgrade – Request MeSpilock Failed (occurs briefly during boot up), then;Blue Screen with : ( & QR code and: SYSTEM PTE MISUSE  After spending 45 minutes on the phone with Dell, we managed to get it to boot by tapping F2 at start-up; then F9; and F10. However, that only works 1 out of 5-6+ start ups. The Dell representative said a “software specialist” would call me the next day to assist. Unfortunately, the call never came, and last night I received an email from Dell advising that it would be $90 for a phone call since it’s software related. Now, I afraid to restart my PC as I don’t know if it will boot up, and I need to use it for work!
