A training troubleshooting issues with laptops part

A+ Training: Troubleshooting Issues With Laptops Part 1

Laptop Power Failure

One of the most common occurrences in laptops is power failure.  Whether it be due to high usage, battery failure or an error, it still can be hard to fix. Locating the problem can be a difficult task, but troubleshooting should help you detect the problem within a reasonable amount of time.

The first trick to troubleshooting accurately is to find out what is not wrong. It is a process of elimination. First of all check out the power points used by completing a lamp test to make sure they are not the problem, and then check that the transformer is working. If your laptop is a newer model, it should have an LED on the transformer to show that it is on or off, as well as a LED on the laptop, which shows that there is a power supply going through. If power is still reaching your laptop, but still it won’t turn on, it may be the battery.

A frazzled or problematic battery isn’t necessarily a major disaster, as most modern laptops can run off the mains without the use of the battery. Make sure the laptop can run without a battery, and then you can remove it and power up your laptop as normal. If you are still experiencing power failure, it may be a problem with power regulation, the main switch board or the ‘on’ button is simply damaged. To test for these you will need to use specialist equipment.

Bear that in mind, with the lower end of the laptop market badly manufactured batteries are used, so it may be simply that this battery has had its life and is now ready to be replaced. There are also a few of measures you can take to prevent battery failure, including regularly discharging the power in the battery. The amount the laptops needs charging and to discharge will depend upon the model, so search online for the requirements for the model. Some models need to be charged for a few hours then discharged, whilst others only need discharging once a week. Taking preventative action is often the best way to save a battery and prolong its life.

Troubleshooting is one of the main roles of an I.T technician, thus if you intend to start a career as an I.T technician by starting your A+ training, it’s vital that you fully understand how to and that you continue to gather information on troubleshooting as technology changes.

Buying toner to save money

Buying Toner to Save Money

I think we’ve reached a consensus that there’s a conspiracy afloat. You go to your local office supply store or membership warehouse, and find the deal of the century on a laser printer, photo printer, or inkjet printer. You take it home and are delighted by the quality of the prints, the speed of the printer, and most of all, that your new printer was incredibly inexpensive. The next thing you know, though, the starter toner cartridge that came with your new printer runs out, and you discover that the replacement cartridge costs about half of what you paid for the printer.
Yes, printer manufacturers are able to offer such low prices on printers because they make so much profit on toner cartridges. At least that’s the case when you buy an Original Equipment Manufacturer, or OEM, inkjet printer cartridge or LaserJet toner cartridge.
You are probably aware that there are other types of ink cartridges and laser toner cartridges available, but perhaps you’ve been wary of them. After all, printer manufacturers warn of dire consequences like equipment ruination unless you buy brand name (or Original Equipment Manufacturer) toner. The truth is, there are compatible inkjet printer cartridges and LaserJet toner cartridges that not only meet, but that actually exceed the specifications of the equipment manufacturers. These cartridges are brand new and provide you with toner or ink that will produce the high-quality prints you’ve come to expect – without compromising the parts or lessening the lifespan of your printer.
In addition to Original Equipment Manufacturer and compatible ink cartridges and toner cartridges, you can also find what are called re-manufactured cartridges. These are different from compatible cartridges in that they are OEM cartridges that have been used and refilled. Good re-manufactured cartridges consist of more than simply filling a used cartridge with ink or toner, though. For example, an inkjet printer cartridge and the print head nozzles will be cleaned. Then, once the inkwells have been filled with ink that matches the ink found in Original Equipment Manufacturer cartridges, the cartridge is extensively tested to ensure that it will do the job. It will, for example, go through tests to ensure it doesn’t leak, its circuitry is functional, and the pressure inside the cartridge is exact.
The key to finding the right kind of laser toner or inkjet ink at the right price is understanding the difference between Original Equipment Manufacturer products, compatible products, and re-manufactured products. Next, you have to find a reputable supplier of compatible toner cartridges and inkjet printer cartridges. The Internet is the best place to start. When you do, you’ll feel more comfortable with taking the plunge and buying something other than the pricey cartridges available at your local office supply store. You’ll be surprised that you can save a ton of money – as much as 85 percent! When you do, that low price you paid for your laser printer, photo printer, or inkjet printer will, indeed, be a bargain.

Standardization of midi technology under the general midi gm standard

Standardization Of Midi Technology Under The General Midi (gm) Standard

The problems that electronic musicians faced with playing their compositions on equipment made by different manufacturers was a serious one in the 1980s. Hook up a MIDI Controller made by one manufacturer to a sound module made by another manufacturer, and your flute solo could come out as a drum solo. You could try adjusting the volume and end up changing the pitch instead. This is because MIDI commands, which are used to control every aspect of the composition from notes played, instrument used, volume, pitch, and many other parameters, are numerical, and once upon a time (meaning the 1980s) different manufacturers used different functions to correspond with different MIDI Command numbers. For example, the number corresponding to a trumpet sound on one brand of equipment might correspond to a harmonica sound on another brand of equipment.
There were many other problems as well, most of them arising from a lack of standardization of the correspondence between MIDI Command numbers and the actual parameters that they adjusted. For this reason, the General MID (GM) standard was created – so that all (or most of) the numbers used to generate any particular MIDI command would do the same thing on any brand of equipment that incorporated the General MIDI standard – for example, the number 12 placed at a certain point in the string of digits that represents any MIDI command now triggers any GM standard sound module to play a Vibraphone sound, and nothing else. This sound may differ somewhat on different sound modules (sound quality will vary depending on how expensive the sound module is and what kind of technology it uses), but at least you won’t end up playing a flute instead of a vibraphone.
The GM standard incorporated a variety of standardizations other than MIDI commands – for example, it required all GM compliant sound modules to be fully multi-timbral – that is, each sound module had to be able to receive MIDI messages on 16 different channels, so that the sound module can play 16 different “patches” (equivalent to 16 different instruments) at once, corresponding to the 16 available MIDI channels.
