Taking Charge of Your Electronics

In the early 14th century, a floor globe would have looked like an alien contraption because Copernicus had not convinced everyone that the world is round just yet. Now, such things are common and every library has at least a basic one, and for the technologically inclined libraries, they may even have one that could tell the time and temperature of the places on the globe. A mere 500 years after finding out that the world does not revolve around the earth, progress has certainly made a lot of leaps, and along with those leaps come portability, and portable chargers.

There's a charger for your mobile phone, another for your MP3 (4 or 5), yet another for your digital camera, and then there's a possibility that you have a portable game console, and the next thing you know, you're struggling with a snake's nest of wires. Not to mention putting yourself in danger of the possibility of blowing a fuse, literally and figuratively.

Modern science is supposed to make life easier, is not?

All the Eggs in One Basket

The solution to that tangled spaghetti of chargers is the electronics charging station, a stationery port that has only ONE wire, yet you can charge up to three electronic devices all at the same place and it can save you a lot of time because you do not ' t have to wait for one gadget to be fully charged before you can use that outlet again, or save you from having to reach in to those tight places for other outlets.

An electronics charging station can look like the space age gadget that it is, sleek metal or smooth plastic or it can be disguised as a night stand organizer, made of wood or leather, and can have many useful drawers that can help organize other little gadgets on your night table or desk, like pens, reading glasses, coins, or even paper clips.

To add to the utility of this charming port, you can get an electronics charging station with a night light in its design, or a vacuum cleaner (yes, a vacuum cleaner). To appeal to the more aesthetically inclined market, one can get a hand painted port that looks anything but an electronics charging station, or one with pastel polka dots for the younger generation, or a nice warm mahogany to blend with your desk and leather desk set .

Wireless Gadgets

There are useful gadgets like the wireless home weather stations that will not take up an extra outlet from your electronics charging station. A home weather station is a lot like a digital alarm clock, but it can tell you the weather inside and outside with forecast icons (clouds, sun, sun behind the clouds, etc.), through sensors strategically placed around your home. It can have up to three sensors feeding the display panel, and a radio-controlled date and time display. Some even have moon phase displays, and clothing suggestions, in digital or full color, or even an animated display.

Electronics Devices And Components

For most of us our day starts with a ring tone of an electric alarm clock. Then as we get ready in the morning we use a couple of other devices ranging from an electric shaver to an electric iron. The point here is that we have barely started our day and most of our morning is spent using various electronic devices and components. The list of electronic products that we use in a week would be so long that most of us would be shocked on seeing the amount of dependence on these products. As you must have realized by now, these Electronic products and components form a major part of our daily life. They either provide us a useful function or they entertain us.

Irrespective of the purpose they perform, we all would agree that we can not survive without these products.

These electronic components have become a major part of our daily life, whether we think so or not. Our dependence on these electronic gizmos is only increasing everyday. Nobody needs to be a technology expert to realize that electronic components play a major role in our lives.

In recent years, the electronics segment has undergone a tremendous transformation. All this has contributed to a new way of life. Miniaturization and integration are the key factors that have fueled the tremendous growth of portable electronics technology. Electronic components & devices have been reduced to hand held devices.

Electronics devices are used for everyday functions. Some of these are the ones that are purely for our interest and entertainment. Electronic devices and components like WiFi (Wireless Fidelity) technology, applications such as Voice over IP (VoIP), web surfing, movie play back, MP3 player, portable gaming devices and camcorders are some glaring examples which provide us entertainment everyday. Items like computers and cell phones are now a necessity rather than a luxury. The consumer electronics segment of devices and components gets improved more and more every year to provide us more functionality, convenience and satisfaction. The gap between entertainment and functionality for the usage of these electronic products and devices is getting closer every day. Electronic devices today are compact, lightweight and functional along with a long life cycle due to the high quality electronic components in their production. The electronic market is changing every day and quickly evolving.

Some of the products being offered today are portable electronic devices such as Portable Media Players (PMPs), Smartphones, & GPS-PDAs, laptop computers, hand-held devices such as cellular phones, personal media devices including the iPod from Apple.

Troubleshooting Electronics

One of the most effective methods for troubleshooting electronics is unplugging power.

The most effective troubleshooting / repair tool available for computers or microprocessor-controlled systems is turning power off, waiting a period of time, and turning power back on.

Here's why it works:

Computers and microprocessors are control systems which are generally not fully controllable. This means that either the hardware or software can put them into a state where normal control inputs have no effect on the system. This topic is called "Controllability" in formal Control Theory jargon.

An analogy would be an Interstate off-ramp with no returning on-ramp. Once you get off, you have to do something abnormal, like back-track several miles on surface roads, to get back on.

From now on, I will use the term "computer" to mean computer or any microprocessor-controlled system. Your microwave, VCR, and fancy coffee pot are non-computer examples.

One state that all functioning computers can recover from is the power-off state. Hardware and software engineers work diligently to make sure a computer can turn on into a known controllable state. Imagine how upset customers would be if, regularly, they took their electronic devices out of the box, flipped the on switch, and nothing happened. You can be sure the manufacturer would hear from the customer, and that the hardware or software engineer at fault would also hear about it in no uncertain terms.

So, how does a computer get into an uncontrollable state?

In hardware, there are many causes for what is called a Single Event Upset (SEU). A power glitch, a cosmic ray passing through an integrated circuit (IC), or an alpha ray from the plastic IC package, can all cause an SEU, possibly changing a logic state (1 to 0 or vice versa), or triggering latchup in the pnpn layer most ICs have. In software, the computer can get done in an infinite loop.

How do you turn your computer off, and how long do you keep it off?

Using the off / on switch or normal software shutdown will cure more than 90 percent of the problems, but not all of them. After turning off the computer, you need to pull the plug from the wall and make sure anything the computer interfaces with (modem, printer, etc.) is also turned off and unplugged. (Power strips are great for this.) If your computer has a battery, such as a laptop does, or a built-in UPS battery, you also need to remove this power source. The reason is that even if you turn off your computer, it still draws vampire power to keep certain monitoring and startup circuits alive – which may be causing the problem.

Now that you've turned it off, how long do you keep it off?

Usually, but not always, 30 seconds is enough. This is because bleeder resistors across capacitors used to be designed to discharge logic, memory, and interface voltages to less than five percent of normal voltage in about this amount of time. It was considered good design practice. These discharge paths were also often included in ICs to remove charge from junctions and internal nodes when not powered.

Today, the discharge resistor is often not included in the design. Cost-savings is one reason, but also because real estate in ICs is so valuable. Active pull-down and pull-up devices, which take less real estate than resistors, are used instead. These work when there is power, but they can be high impedance with power removed. What this means is that a charge on system components and IC capacitance can keep the computer in an uncontrollable state for a longer time. As computers get "better" you need to leave them off longer.

What's my personal approach?

I turn the computer off (and remove the battery in a laptop), wait 30 seconds, replace the battery if necessary, and turn it on. If this does not cure the problem, I turn it off, unplug everything, remove battery backup, wait several minutes (up to 30 minutes), and try again. If this does not work, then I leave it off overnight.

If these steps are not successful, re-cycling power will not solve the problem.

As those of you who have visited my website know, I include a personal anecdote for every problem / solution description I provide. Here is my anecdote for this problem:

When I was newly married, my wife would ask me to fix this or that electronic device that went out. Confidently, I would instruct her to pull the plug, reverse it (before plugs were polarized), wait 30 seconds, and plug it back in. She would first complain that this would not help, and then was amazed when it solved the problem.

Now, 47 years later, she just reported that the microwave went out. Without a word from me, she reached back behind the cabinet, pulled the plug for 30 seconds, plugged it back in, and reset the clock. She now accepts this as the best way to trouble-shoot / repair any electronic equipment. From her own practical experience, she knows it works most of the time.

The bottom line: One of the most effective methods for troubleshooting electronics is unplugging power. The time-tested technique is to turn it off, pull the plug, remove the battery, wait, replace the battery, plug it back in, and turn it back on. And best of all … this powerful method of troubleshooting electronics is free!
