Which step precedes plugging in the AC adapter during a Latitude Self-Heal Recovery?

In the context of a Latitude Self-Heal Recovery, the correct step that precedes plugging in the AC adapter is disconnecting the coin-cell (CMOS) battery. This step is crucial as it serves to reset the device’s BIOS settings by clearing any stored configuration that may be causing issues. Disconnecting the CMOS battery helps in ensuring that any erroneous settings or corruption is eliminated before proceeding with the recovery process.

After achieving a reset, the system can then use the AC adapter to power on and enter the recovery mode or attempt to restore previous system configurations. This sequence is important for preparing the laptop for effective self-healing or troubleshooting, as it paves the way for a clean recovery process free from previous settings that could hinder it.

Other options, while they may seem relevant, do not follow the specific protocol designed for self-heal recovery as effectively or directly. Certain actions, such as removing the primary battery or checking the LCD cable, are generally relevant in a broader context of maintenance or initial assessments but are not specifically aimed at facilitating the recovery process. Releasing flea power pertains to discharging any residual current and is a helpful practice but is not the immediate precursor to plugging in the AC adapter in this scenario.
