Notes Chapter 1 Flashcards
What do most computer repair companies require?
Hint document
Most computer repair companies require an authorization of work or work authorization form document with company name and details/times of when and what will occur during the job.
Techno-babble, what is it?
Techno-babble is the use of (often nonsensical) jargon and technical terms to intimidate and silence a challenge to a technical issue.
Computing devices and ESD
All computing devices are well protected against ESD on the outside. Unless you take a screwdriver or pry tool and open up a PC or other computing device, you don’t need to concern yourself with ESD.
ESD only happens when…
When two objects that store different amounts ( the hip electrical term to use is potential ) of static electricity come in contact.
What’s the secret to avoiding ESD?
Keep you and the parts of the computer you touch at the same electrical potential, otherwise known as grounding yourself to the computing device.
You can accomplish this by connecting yourself to the computer via an electrostatic discharge ESD strap.
ESD strap
Make sure the metal plate on the ESD strap touches the skin or your wrist. Don’t put it on over the sleeve on a long-sleeved shirt.
One of the biggest issues when working with a computer occurs when?
It occurs if you find yourself pulling out parts from the computer, it no longer has contact with the system and may pick up static from other sources. We use antistatic mats to eliminate this risk.
ESD strap resistors
Devices that stop or resist the flow of electricity — to prevent a static charge from racing through the device. These resistors can fail over time, so it’s always a good idea to read the documentation that comes with your antistatic tools to see how to test those small resistors properly.
What does a typical technical toolkit have in it?
- Torx wrench
- a nut driver or two
- pair of plastic tweezers
- parts retriever
- hemostat
- Phillips head and flat head screwdrivers
- IC extractor
- extra parts tube
- multi-driver
Non-contact thermometer
Is another useful tool to have on hand. Not only is it more precise than your hand, it can read the temperature of components deep in hard to reach corners of a device.
