Which of the following will help reduce the threat of static discharge when working on computer hardware?

Short for electrostatic discharge, ESD is one of the few things you can do to damage or destroy your computer or parts in your computer. Like the shock you receive when rubbing your feet on the carpet and touching something metal, ESD can occur when working in your computer and can cause damage to components. ESD can occur without you feeling a shock and only occurs while working inside a computer or handling an expansion card or other hardware.

Preventing ESD and grounding yourself

The best method of preventing ESD is to use an ESD wrist strap, grounding mat, or grounding workbench. However, because most users don't have such items, we've included the following steps to reduce the chances of ESD as much as possible.

Tip

If you plan on working inside a computer more than once, we highly recommend purchasing and using an antistatic wristband.

  • Zero potential - Most importantly, make sure you and the computer are at zero potential by continuously touching an unpainted metal surface of the chassis or the computer power supply case.
  • Standing - Always be standing when working inside the computer. If you are sitting on a chair or the floor, it can generate more electrostatic.
  • Cords - Disconnect everything from the back of the computer (e.g., power cord, monitor, and USB cables).
  • Clothes - Make sure not to wear any clothing that conducts an electrical charge, such as a wool sweater.
  • Weather - Electrical storms can increase the ESD risk; if it can wait, try not to work on a computer during an electrical storm.
  • Accessories - To help reduce ESD and help prevent other problems, it is also a good idea to remove all jewelry.
  • Surface - Standing on a hard surface, and the computer or other electrostatic sensitive devices should be on the table.

ESD tools

Which of the following will help reduce the threat of static discharge when working on computer hardware?

When working inside the computer, have at the very least a wrist strap to help protect the sensitive components from ESD damage. If you run a business that deals with lots of sensitive equipment, a grounding mat, and grounding table is also highly recommended.

  • Static
  • Wrist strap

Damaged hardware

If the computer no longer boots after working inside of it, try the below recommendations.

  1. If you have added any new parts, remove them and try to boot the computer again. If the computer boots, the part was either not connected properly or incompatible with the computer. Try it again to help verify.
  2. If the computer still does not boot properly after removing all new hardware or you didn't add new hardware, make sure all cables and expansion cards are connected to the computer.
  3. Make sure each expansion card is seated firmly and not partially seated.
  4. Unfortunately, if the computer still does not properly boot, something may have been damaged and is causing it not to work. If the computer is beeping abnormally, refer to our beep codes page for recommendations and beep code listings.

Which of the following would best protect you from static electricity buildup?

Which of the following would BEST protect you from static electricity buildup? To prevent ESD when replacing internal computer components, you attach an anti-static wrist strap to your wrist.

Which of the following are safe methods of lifting heavy objects?

Bend your hips and knees to squat down to your load, keep it close to your body, and straighten your legs to lift. Never lift a heavy object above shoulder level. Avoid turning or twisting your body while lifting or holding a heavy object.

Which of the following are most helpful in keeping a computer cool?

The easiest thing you can do to cool down your PC is to give it some breathing room. Make sure nothing is covering the ventilation ducts so hot air can escape and cool air can flow in. You should also avoid storing your computer in hot and confined spaces, as this can contribute to overheating.

What is your top priority when responding to emergencies and hazardous situations?

When an emergency occurs, the first priority is always life safety. The second priority is the stabilization of the incident. There are many actions that can be taken to stabilize an incident and minimize potential damage. First aid and CPR by trained employees can save lives.
