A technician is preparing to open a laptop chassis to replace a degraded internal battery and install a secondary M.2 solid-state drive. Which of the following safety protocols and hardware handling precautions should the technician perform before touching internal system components? (Select TWO.)
- Disconnect the external AC power adapter and unplug the internal battery cable from the motherboard.Answer
- Attach an antistatic wrist strap connected to an equipment ground to prevent electrostatic discharge.Answer
- CVerify compatibility for standard 288-pin desktop DIMM modules to ensure dual-channel memory expansion.
- DPerform a manual high-voltage discharge on the CCFL display inverter board capacitors.
Answer
Disconnect the external AC power adapter and unplug the internal battery cable, and attach an antistatic wrist strap connected to an equipment ground.
Safe technician procedures for internal laptop repairs require completely removing power by disconnecting both the AC power source and internal battery connection, along with enforcing electrostatic discharge (ESD) protection through a grounded wrist strap.
