Device configuration overlay (DCO) is a hidden area on many of today's hard disk drives (HDDs). Usually when information is stored in either the DCO or host protected area (HPA), it is not accessible by the BIOS (or UEFI), OS, or the user.

IBM ThinkPad and LG notebooks hide system restore software in HPA. HPA is also used by various theft recovery and monitoring service vendors.

Memory protection is a way to control memory access rights on a computer, and is a part of most modern instruction set architectures and operating systems.The main purpose of memory protection is to prevent a process from accessing memory that has not been allocated to it.
Given below are some solutions to resolve the issue. After trying the first solution, check whether the issue is resolved. If the status still shows "Your computer is not fully protected," try the suggested solutions until the issue is resolved. Run the automatic fix

Forms of read-only memory were employed as non-volatile storage for programs in most early stored-program computers, such as ENIAC after 1948. (Until then it was not a stored-program computer as every program had to be manually ...
