Computer Repair Safety

Everyday people like you are injured or lose important systems and data when trying to repair their computers. You need to take certain precautions to prevent disaster. To get started, you’ll need to know how to protect your computer systems and data. This step can’t be overlooked! Wash your hands to prevent spreading grease or dirt to your computer components. When handling components be sure to only touch the edges, especially the chips on the motherboards themselves.

Understand that even your skin oils can damage the inside of a computer. Static electricity can also be your enemy, especially if you are not aware of it. Simply put, it can damage components beyond repair. The equivalent of about 6,000 volts of electricity can be transmitted easily just by walking on carpet, and that is enough static electricity to completely fry your computer and all its components. Even smaller amounts of electricity can damage components. So, a surge protector must be used when you plug your system in. Computers and equipment are sensitive to changes in voltage, so a surge protector will protect them against large spikes in voltage but not an outage. A battery backup system is the best way to protect against a power outage, as it provides the system with constant voltage.

To keep you safe when working on computers follow these guidelines:

Remove rings, watches & necklaces

These personal effects are often made of conductive metals which, aside from possibly damaging components by striking them, could also short circuit pieces of your computer or transmit damaging amounts of static electricity.

Unplug all power sources & cables from computer

Working on computers that are plugged in is an easy recipe for damaging the hardware. If the machine powers up in the middle of you plugging in a component, chances are the component and perhaps the motherboard itself may sustain critical damage. Modern processors will overheat in as little as 7 seconds without their heat sink attached. There are many more ways that carelessness on this subject could damage hardware.

Hold the off button for 10 seconds before working on any computer

Computers that have been plugged in have a residual charge residing in their electrical components. If the computer is not properly grounded for any number of reasons the residual charge has a possibility of damaging the machine or interfering with its ability to correctly function. Similar to the previous section, the residual charge is usually enough to actually power up the machine for a moment, resulting in massive damage to components if they are in the middle of an install or un-installation procedure.

Never open your computer’s power supply or monitor

Power supplies and older CRT style monitors both contain capacitors that hold enough charge to stop the human heart. They can and have killed people in the past. Even if you know what you are doing and take the proper precautions, neither component is worth the danger at this point when the prices of new LCD monitors and replacement power supplies are so low.

Use an anti-static wrist strap

We spoke earlier about how even the slightest static discharge can damage components. Not all damage is immediately apparent either, you may not have damaged a component in such a way to make it fail but instead of its usual 10 year operating life it will now last a total of 3 years before it fails due to the stress of the shock it received. An anti-static wrist strap is an easy and safe way to make sure you are grounded and not in danger of transferring energy into your PC components. Sure, you could maintain a ground by hanging onto the case the entire time, but it is much easier and safer to have both hands available for work and a ground that does not require you to think about maintaining it. This is especially true for the computer repair beginner, where an accident could easily hinder your plans to proceed further in this field. Also remember, how you treat your own PC components is your business, but when you are working on someone else’s hardware it is important to maintain good standards in safety and professionalism. The anti-static wrist strap helps serve that goal.

10 Benefits of Computer Repair Service.

 

In the Tanzania, there are approximately 18,765up to to date. 

Instead of making repairs on your computer, it can be very beneficial to take it to one of these many repair shops.

Our repair service will ultimately save you time and money in the long run. 

Keep reading to learn about ten NorthTECH Computers benefits today!

1. Cost-Effective 

When you take your computer in for repairs, you might expect to shell out a lot of money. Depending on the issue, computer repair services could get expensive.

However, in the end, it's cost-effective to hire a computer repair service. If you try to fix your computer on your own, you might end up spending a lot more money if you make mistakes. 

A repair shop also gets parts for wholesale prices. Ordering single parts for yourself can cost a lot more money as they add up. Consult your Omaha computer repair shop before tackling the restoration on your own. 

2. Time-Saving

Time adds up as you try to fix your computer's problem yourself. Most likely, you don't have the proper training to get the job done. So, you'll be spending lots of time trying to diagnose the problem.

Once you find the problem, you'll need to order the correct parts, meaning you'll be waiting for delivery. Then, you'll need to spend time learning how to make the proper repairs. 

Since computer repair shops are professionals and keep an inventory of most parts, it'll take half the time. They'll quickly get things done so you can return to using your computer as soon as possible. 

3. Efficiency

If you're attempting to repair your computer on your own, you'll soon find that lack of experience will take a toll. This inexperience can cause even more problems or uncertainty, and you may never end up resolving the issue. 

Your repairman is an expert in this field and can most likely figure out the problem in seconds. Their knowledge will allow them to fix your computer the right way to enhance its performance. 

For example, a computer screen repair can take a professional a few minutes to fix and ensure it's working correctly once installed. If you tried this on your own, you could be facing a day's work with no guarantee that it will perform flawlessly. 

4. File and Data Saving

If you're like me, you have thousands of pictures and important files saved to your computer. Now, if your computer is ever failing to work due to the system, screen, or keyboard issues, you're in danger of losing that data. 

Often, people will take on repairs and lose the data by accidentally deleting operating system files. Their inexperience can also cause further damage to the hard drive, making it impossible to retrieve files. 

Your professional repair service will ensure your data is safe and saved. This professional process first involves data safety, meaning it will take the proper precautions to protect your data. 

5. Damage Prevention

When you decide to fix your computer yourself, you risk creating more damage than what you started. A small problem could turn into a large one, making repairs even harder to do. These new repairs could add more time and money to your overall bill. 

Your repair service provider has all the proper tools and knowledge to ensure no further damages occur. Their training allows them to keep an eye out for other potential problems that could arise, keeping them one step ahead.

6. Upgrades

Taking your computer to the shop not only allows you to get the proper repairs, but it also allows you to get beneficial upgrades. You may not realize that your computer needs any updates until your repairman lets you know. 

They will upgrade your hardware and make any necessary updates when it's in their care. These upgrades will also improve your computer's performance, allowing you to have a better working system.   

7. Ease of Mind

Everyday life is filled with many stresses thanks to work, relationships, and schedules. Taking on computer repairs can add even more stress to your daily life as the problems go unfinished. Your busy life will only become harder to deal with when an essential tool, such as your computer, is out of service. 

Instead of wasting your time and creating unnecessary anxiety, find a computer repair shop near you. Their services will free up time in your schedule, allowing you to focus on more important things. Your mind will be put to ease knowing they'll get the job done correctly as quickly as possible. 

8. Tips 

After your local shop has done your repairs, they will usually provide further assistance. They do this by giving you helpful tips and tricks to avoid the same damages. 

Often, they will notice other ways you can improve your computer's use and give you detailed advice. This advice can include maintenance, update, or functioning tips. 

9. Tools

If you begin making repairs yourself, you'll soon start realizing you don't have half the tools you'll need. Computer repairs often require specialized tools that the average joe usually doesn't have on hand. Professionals have all the necessary tools to dig into your computer's structure.

10. Maintenance

Once your repair shop completes fixing any issues, they'll often suggest regular maintenance. If you agree, they will set up a schedule for you to bring in your computer. 

This routine maintenance can help detect any potential problem or enhance performance. With these maintenance appointments, you'll always have a healthy running computer. 

Managed antivirus services that offer around-the-clock protection are also available to keep your data and personal information safe.

Why air conditioning service is important

Air conditioning service is not only important, it’s necessary! With timely maintenance and convenient repairs, you can ensure your air conditioning system is always working properly. It must be serviced twice yearly to keep your air conditioner in top condition. Once a year. Once during the season and once at the end of the season. Here are the top reasons why air conditioning service is so important.

1. Improve air quality:

 

Regular maintenance of your air conditioner keeps the air filter clean. Air in homes and offices moves through air conditioning units daily, passing through filters, vents, and ducts. After being used for some time, bacteria, dirt, and dust will accumulate inside the air conditioner, causing indoor air quality to deteriorate. This can cause serious health problems like allergies, asthma, and lung infections.

    Regular air conditioning services will improve the air quality in your home and business and spread clean air. Hire experts in Arusha and get all AC services delivered to your doorstep in just a few clicks.

2. Extend lifespan:

An air conditioner that is regularly checked and maintained can last a long time without needing to be replaced, which is expensive. In this case, our air conditioning technicians will find out and fix minor issues before they become serious to prevent future damage.

Therefore, it is highly recommended that commercial customers have major service twice a year and general service once a month, and our experts also recommend that residential customers twice a year for main service and once every three months for a long time to use their air conditioning equipment and extend its service life.

 


3. Reduce failures:

 

Professional air conditioning repair technicians will inspect and clean all parts. They will also ensure that the filters are washed and cleaned on time. This will prevent major malfunctions or other problems with the air conditioning unit. 

4. Save electricity bills:

 

If your air conditioner is in good condition, i.e., clean and free of clogs and leaks, it will use less energy. Air conditioning maintenance can reduce your energy bill, help you cut down your expenses, and provide better cooling and airflow.

5. Avoid costly replacements:

 

Repaired air conditioners do not need to be replaced. Replacing air conditioners is expensive, and regular air conditioner maintenance can help you save money and provide better cooling. The lifespan of air conditioning units is also longer, i.e., 5 to 8 years.

6. Eliminate bad air:

Sometimes, your office or home air conditioner emits a bad smell caused by bacteria, fungus, and dirt stored in the air conditioner. In this case, you need to call in an air conditioner repair expert to check the condition of your air conditioner and remove the odour from your home and office.

 

Choose the right air conditioning repair service.

 

There are many things to consider when choosing a trustworthy HVAC company to repair your air conditioner. Of course, you can always wait until the problem occurs and choose one of the first companies that show up on Google. Whether you’re considering replacing your old air conditioning system or repairing it first, you need the right contractor. With all this confusion and choice, how do you avoid choosing the right contractor for your home improvement project? However, research before your air conditioner needs repair to save you time, money, and possibly the hassle of dealing with an incompetent company.

License/Certificate

This is the first and most important thing to consider before hiring a professional air conditioning repair technician to repair your air conditioning system. Professional technicians must have the appropriate air conditioning repair certificates and licenses to work on this equipment. Certification and licensing only mean that the air conditioner repair technician is well trained and has practiced in this field of appliances for a specified period to gain the basic skills to handle any air conditioner problem. Only the most qualified people can be licensed and certified, which is why it is a critical point in the investigation.

Quality technician

A company is only as good as its employees. Finding a company invested in its employees and technicians means it wants the best for its customers. When looking for an air conditioning repair company, look for signs that its technicians are NATE certified. Additionally, good companies provide regular learning opportunities for their technical staff. Finally, just like a company, technicians become wiser with industry experience. The company you choose should invest the time and resources in its technical staff.

Service hours

As you know, Monday-Friday 8-5 does not apply to air conditioning repair. You never know when you’ll need air conditioning professionals, so it’s best to look for a company that offers 24/7 emergency services. The air conditioning repair company you choose should be there whenever you need it, including all day, weekends, and holidays. Now be careful, as some companies claim to offer 24/7 emergency service but then charge more for repairs done outside of normal business hours. If necessary, call the company and ask them from the beginning whether the price for this emergency service is higher.

Experience is important

Whenever you plan to make repairs to your home, it is important to find an experienced company. A company that’s been around a long time is doing something right. With years of experience in the industry, they may have hands-on experience that other young companies may need to gain. A company that has been in business for many years will know how to treat customers and organize operations to improve your overall experience.

Price/Rates

When the cost of air conditioning repair seems too high to be true, be careful. As the old saying goes, you get what you pay for. On the other hand, you should not take out a loan to repair your air conditioner. To help keep costs down, some companies offer special services that give you discounts. Also, try to find a company that offers free repair estimates so you don’t have to pay to have the problem evaluated.

Service Guarantee

It’s always great to experience great service for the first time, but it’s a plus when you find a company that offers a service guarantee! Air conditioning repair is complex; many things can go wrong at times. Therefore, when a business is willing to provide a guarantee on its services, it has sufficient confidence in the quality of its services; if something goes wrong for any reason, we will not hold you responsible.

Brand and model

Air conditioning repair is not one size that fits all, as there are so many makes and models that a company should have the knowledge and equipment to handle them all. Ensure the right ac service you choose has expertise in repairing all models of air conditioning units.

Survey First 

One of the best ways to find a right ac repair service is to ask your family and friends. Even if they had a bad experience, you can check your list off with this company instead of wasting time. People love to share their experiences with others and pass on their favourite companies for others to use.

Repairmax

Repairmax air conditioning repair services can help you achieve this goal. These references are simple ways to care for your home and keep things running smoothly.

 Seven most common access control system cable wiring mistakes

So what are the most common wiring mistakes we see with access control systems?

   1} Using the wrong cable type
   2}Not using the plenum rated cables in a plenum ceiling
   3}Improper wiring techniques
   4}Not keeping the low-voltage wires separate from high-voltage electrical wires
   5}Not using a licensed elevator contractor
   6} Creating unnecessary visual distractions
   7} Not reviewing the wiring diagram with your access control system provider

Let's explore each of these topics in detail below.
1. Using the wrong cable type

Many people assume Category 5 (Cat 5) cable is good for everything, but that is not the case. Cat 5 should only be used for network connections. In an access control system, use Cat 5 to connect the ACU to the LAN (internet).

To connect credential readers to the ACU, use 22 gauge 6 conductor shielded cables. Credential readers must be within a 500-foot distance from the ACU for the reader to work properly. When the credential readers are located further than 500 feet, we often install an additional ACU or deploy a different method that uses Cat 5 cable.

For connecting an electric strike or a mag lock to the ACU, use 18 gauge 2 conductor cables. For exit and egress devices, use 22 gauge 4 conductors (or 6 conductors depending on the egress device) cables.

These cables are not like Coke versus Pepsi or Energizer versus Duracell. Never substitute one cable type for another. If a technician accidentally uses the wrong cable type, the device will experience unexplained interruptions or fail to work. 2. Not using the plenum rated cables in a plenum ceiling

If your space has a plenum ceiling, the cables used in the ceiling space need to be plenum rated to avoid a building code violation. A plenum is a space between the structural ceiling and a drop-down ceiling used for air circulation for heating, cooling, and ventilation. Plenum-rated cables have special insulation that makes them fire-resistant and non-toxic during a fire condition.

Even for a very experienced technician, it can be difficult at times to confirm if a ceiling is a plenum ceiling, especially in older buildings. When in doubt, we use plenum-rated cables despite their higher cost because it’s less expensive to wire once than wire twice.
3. Improper wiring techniques

We often see wires that are dragged through sharp metal ceiling parts, held in place by staples, or fastened to electrical conduits and sprinkler pipes. These improper wiring techniques can damage the metal strands inside the wires, which could result in an electrical short and shortened lifespan of the cables.

Also, watch out for cable wires without sufficient support. If they look like lights hanging on a Christmas tree, the wiring job is probably not in compliance with the local building codes that dictate the wiring support requirements.

4. Not keeping the low-voltage wires separate from high-voltage electrical wires

All the cables used for an access control system are low-voltage wires. They need to be kept completely separate from high-voltage electrical wires to prevent induced voltage or interference that could prevent your access control cables from transmitting signals properly.
5. Not using a licensed elevator contractor

A reputable security company will not try to connect to the elevator on its own because each elevator is set up differently. If you need to connect your access control system to the elevator control system, make sure your access provider coordinates with a licensed elevator contractor.
6. Creating unnecessary visual distractions

Aesthetics is of huge importance to many businesses, and not just for high-end art galleries and retail boutiques. It’s important to plan ahead how the wiring will impact the look of the space. Whenever possible, skilled technicians will run cables through the walls, the ceiling, and other discreet spaces to ensure a seamless interior look. Even if you can’t completely hide the wires, there are tricks to minimize the visual distraction.

Discuss your aesthetic expectations with your access control system provider early in the planning process. It’s common for us to send out a consultant to review the interior design elements, identify potential issues and run a technical assessment to come up with solutions for difficult areas before sending out technicians.
7. Not reviewing the wiring diagram with your access control system provider

Ask to review a detailed wiring diagram to ensure all the readers and locks are correctly marked and the correct cable types will be used. Here’s an example of a diagram we use with our own technicians and customers.
