Zorluk: KolayLaptop Hardware Components and Upgrades

A technician is preparing to replace an internal M.2 solid-state drive inside a corporate laptop. After powering off the device and removing the chassis enclosure, which of the following actions should the technician perform first to prevent electrical damage to internal components?

  1. Disconnect the internal battery cable from the motherboard.Cevap
  2. B
    Perform a deep battery discharge cycle to drain all residual power.
  3. C
    Install a full-sized dual inline memory module (DIMM) to ground the board.
  4. D
    Connect a display inverter board to discharge high-voltage capacitors.

Cevap

Disconnect the internal battery cable from the motherboard.
Disconnecting the internal battery cable immediately isolates the system board from all power sources. Even when turned off, laptop motherboards maintain active standby power circuits that can short-circuit and damage delicate surface-mount components if touched by tools or hardware during repair.

Adım Adım Çözüm

1
Identify the primary power isolation procedure required during laptop disassembly.
Recognize that modern laptops retain standby power from internal batteries even when powered down.
Internal electrical potential can cause short circuits if metal tools or components touch active circuit traces.
2
Select the correct component isolation action prior to handling internal storage drives.
Disconnecting the battery connection safely de-energizes the motherboard.
This guarantees an electrically safe environment for installing or removing internal laptop hardware.
