Encountered Error Messages and Solutions

I encounter many errors with devices; some of which have no solutions posted online. I’m publishing them here hoping to help others desperately searching for answers.

Error Message (s)MM_FreeBlk.c Line : 501 PJL
Internal Error Power Off/On
MM_AllocBlk.c : Line 611 DS
EncounterAttempted to print through USB Cable connection after installing driver from HP on Windows 11 Pro 25H2. Tried a different USB cable and computer and the error remained.

Error Message (s)Unable to boot from USB Drive – Not found
EncounterAttempted to boot off several USB Drives including NVMe drive inside enclosure and also regular USB Flash Drives. Disabled and Enabled Secured Boot – reset BIOS to defaults – Boot Menu would not detect any other drive aside from the Internal SATA drive as can be seen in this Boot Menu picture. USB drives were plugged in to all ports, front and back and also the single USB-C port included with this PC.
SolutionUses a 16 GB Flash drive. For some reason these PCs are limited to only detecting drives no bigger than 16 GB. Once a Flash drive was prepared with only 16 GB capacity, the Boot Menu changed and detected the flash drive as seen here.

DeviceHP Pavilion All-in-One – 27-r114

Error Message (s)The BIOS you are installing is older than the current version in the system and cannot be executed.
EncounterI visited the product download page for this HP PC and downloaded the latest BIOS update package. I received the above error after executing it, so I tried the 2nd to last update and that one worked.
