Which precaution should be taken while servicing an HP PC?

It is crucial to ensure that the device is powered off and unplugged while servicing an HP PC to protect both the technician and the equipment. When a device is powered off and disconnected from the power source, the risk of electrical shock is minimized, and the chances of causing a short circuit or other electrical-related damage are significantly reduced.

Additionally, working on an unplugged device prevents any accidental power-on scenarios that may occur if an internal component is adjusted or if tools come into contact with live circuitry. This precaution also mitigates the risk of damaging sensitive components due to static electricity, which can be exacerbated when devices are powered on.

The focus on safety protocols in servicing tasks helps create a safer work environment and preserves the integrity of the hardware.
