Answer: B

Explanation:

Disconnect the laptop from any power source and remove the battery To ensure personal safety, it is essential to disconnect the laptop from all power sources and remove the battery before starting any repair, especially on electrical components like an LCD screen. This prevents any electrical shock or short-circuiting during the repair.

Option A is incorrect because working on a metal surface could increase the risk of electrical conductivity and shock.

Option C is incorrect because using a wet cloth can lead to moisture entering the device, which is hazardous.

Option D is incorrect as testing the screen while connected to a power source can be dangerous and does not contribute to personal safety.
