Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✓

  Shut down laptop and unplug, remove battery, locate and open RAM compartment, insert new RAM module, replace compartment cover and reinsert battery, then power on to test.

  Why this is correct

  This sequence is correct because it strictly adheres to laptop service safety: shutting down and unplugging removes the AC supply, and removing the battery eliminates the last source of power before any internal component is handled. Opening the RAM compartment only after the battery is out prevents accidental short circuits and protects the motherboard and memory module from electrical damage. After the new module is fully seated in its slot, replacing the cover and reinstalling the battery before powering on verifies clean assembly and allows POST to confirm the upgrade.

• ✗

  Shut down laptop and unplug, locate and open RAM compartment, remove battery, insert new RAM module, replace compartment cover and reinsert battery, then power on to test.

  Why it's wrong here

  This order is wrong because opening the RAM compartment while the battery remains installed leaves the motherboard live with battery power. Any accidental contact between a screwdriver, the RAM module, or a stray hand and trace or socket can cause a short circuit that may destroy the system board or the memory itself. The safe procedure always removes the battery immediately after unplugging, before any cover over internal components is removed, ensuring the board is fully de-energized for the upgrade.

• ✗

  Shut down laptop and unplug, remove battery, insert new RAM module, locate and open RAM compartment, replace compartment cover and reinsert battery, then power on to test.

  Why it's wrong here

  This phrase is physically impossible: you cannot insert a RAM module into a slot that is still enclosed under the laptop's access panel. Even if you somehow managed to pry the module past the closed cover, you would bypass the proper anti-static and safety steps and risk damaging the module's edge connector. The correct order requires that the compartment be opened first to expose the RAM slot, and that this happens only after the battery is removed—so this sequence is both unsafe and mechanically invalid.

• ✗

  Shut down laptop and unplug, locate and open RAM compartment, insert new RAM module, remove battery, replace compartment cover and reinsert battery, then power on to test.

  Why it's wrong here

  This order fails because it calls for installing the new RAM module before the battery is removed, meaning the laptop's motherboard is still energized during the module insertion. Handling sensitive components while battery power remains connected dramatically raises the risk of electrostatic discharge or a short from the module's gold contacts to nearby circuitry. Proper procedure mandates battery removal first, before even opening the compartment, so any RAM manipulation occurs on a completely powerless board; deferring battery removal until after installation is a critical safety violation.
