What are the two steps that must be taken before cleaning a laptop computer?

Before cleaning a laptop computer, it is essential to ensure safety and prevent any potential damage to the device. Disconnecting the laptop from the electrical outlet and removing the installed batteries serve as critical steps in this process.

The primary reason for these actions is to eliminate any risk of electrical shock while cleaning, especially if cleaning involves areas like the keyboard or other openings where moisture could accidentally enter the device. By disconnecting the power source and removing the batteries, the technician can safely clean the laptop without worrying about short circuits or damaging the internal components.

Moreover, this process helps to ensure that the laptop is entirely powered down, which is important when handling sensitive components or applying cleaning solutions to non-electrical surfaces. Taking these precautions sets a foundational safety standard, making it the appropriate choice before initiating any cleaning activities on the device.
