The most likely reason that the system is not utilizing all the available RAM is that it is running a 32-bit OS. A 32-bit OS can only address up to 4GB of RAM, and some of that is reserved for hardware and system use1. Therefore, even if the technician installed 8GB of RAM, the system can only use around 3.5GB of usable RAM. To use the full 8GB of RAM, the technician would need to install a 64-bit OS, which can address much more memory2. The system missing updates, the system’s memory failing, or the system requiring BIOS updates are not likely to cause this issue.

When a user rotates a cell phone horizontally to read emails and the display remains vertical, even though the settings indicate autorotate is on, this is typically due to a problem with the phone's accelerometer. The accelerometer is the sensor that detects changes in the phone's orientation and adjusts the display accordingly. If the accelerometer is not calibrated correctly, the display may not rotate as expected.

Recalibrating the accelerometer is the most likely solution to this issue. The process for recalibrating the accelerometer can vary depending on the specific device and operating system, but it typically involves going to the device's settings and finding the option to calibrate or reset the sensor. Users may need to search their device's documentation or online resources to find specific instructions for their device.

After implementing a change authorized by the change advisory board (CAB), the technician should document the date and time of change as part of the post-implementation review. This helps to track the change history, verify the success of the change, and identify any issues or incidents caused by the change1. Documenting the purpose of the change, the risk level, and the findings of the sandbox test are all part of the pre-implementation activities that should be done before submitting the change request to the CAB2.

Drilling and incinerating are physical destruction methods that make the data on hard drives unrecoverable. Standard formatting, erasing and low-level formatting are logical methods that can be reversed with data recovery tools. Recycling is not a destruction method at all.
