Computer Repair Tools

By Thomas Morva

Have you ever found yourself up to your elbows in computer wires and chips using your wife's toenail clippers to try and nip off an extra wire? You think you might be able to get your project complete before midnight, when you suddenly realize those clippers aren't going to work without taking out half your motherboard. Substituting computer tools with household things never ensures that your computer is repaired. Still, most people will try almost anything to save money. However, in the case of good computer repair tools, you should never skimp on quality or specialty.

There are millions of computer repair service provider companies who render great support providing all the necessary computer repair tools.

Laptop Computers


How to choose Laptop Computer
By Michael M. Johnson

Laptops are an increasingly popular product catering to professionals and casual users alike. However, it can be very difficult choosing which laptop is good for you and with so many specifications, as well as such a variety of choice, picking the right one can be a very difficult task. This short guide aims to help show you how to choose a laptop computer.

Think about your needs

Some people may think they need a laptop when really a desktop PC would do just as well. The benefit of buying a desktop over a laptop is price - desktops are far cheaper. However, if you need something portable then a laptop is the definitive solution.

It's important to take the time to work out what you really need to get from your laptop. There's no point in spending $2000 on a top of the range laptop when all you need to do is check emails on it.

If your needs are primarily checking emails and writing documents then a low cost laptop will be all you need. If you plan to watch movies and burn files to disk then a middle-range laptop would suit you better. Top of the range laptops are only really necessary for playing games with advanced graphics or for handling programs which need a lot of computer power such as graphical design packages.

Important features

The key features of a laptop are its battery life, processor speed, RAM memory, and hard drive storage capacity. A DVD player/burner is another popular feature, as well as the size and weight. Finally, in high end laptops graphics cards are also important. You may also want to take note of whether MS Office applications (or equivalent) are bundled with the computer or not if you intend to create written documents.

Buying the laptop

It's really important to shop around when you look for a laptop. Deals vary greatly from place to place, but as a general rule the Internet is a great place to start your search.

Computer Printers


Which Printer? Right Technology, Right Choice

By Jimi St. Pierre

Whether you are responsible for a small home-based business, or a large company with many departments and workgroups, there are continuous choices to be made on the procurement of office equipment. Not least amongst these, is the selection of the appropriate printer technology for your business needs? Here in outline are the various technologies and their appropriate environment.

Personal Ink-Jets

Useful for one individual or a workgroup with a minimal colour printing needs, a low-cost personal ink-jet will be the best choice. Personal inkjet printers offer a low initial cost, plus the flexibility to print on a variety of media, such as promotional materials.

Business Ink-Jets

In a bigger business environment, or one where colour output is a major requirement, the workload is likely to be too great for a personal inkjet printer. Thus a unit designed specifically for business will fit the bill, offering a lower cost per page. Many business inkjets employ ink-saving technology and modular cartridges, which avoid the need to change the colour when you change the black and white cartridges, for example.

Laser Printers

Large companies demand more output of all kinds. Perhaps also the demand for colour output on standard-size paper may be addressed with a laser printer

Laser printers have invariably offered monochrome output in the past, but more and more colour-capable lasers are coming onto the market. For organizations with a heavy black-only output though, they still offer the lowest cost of monochrome printing, as opposed to ink-jets which offer a lower cost for colour output. Even so, the picture is changing, and there are some surprisingly low-cost colour lasers available.

Large or Wide Format Printers

Design work or over-size documents for displays require a special kind of printer – a large format printer capable of printing on very large paper (or other media) sheets. Factors to consider here are quality of output, colour capability, speed, networking capability and additional functions such as scanning and copying.

Photo Printers

A photo printer is essentially a personal colour ink-jet with a higher capability for printing on special photo paper. Naturally useful in the home, such printers have their use in the business environment - for example when there is a need to include quality photos in presentation packs for marketing purposes, or for use in training materials.

Business Colour or Full Colour?

For businesses requiring mission-critical exact colour reproduction (such as in the preparation of colour proofs, for example), then it is important to differentiate between machine which offer Black and Business Colour as opposed to the higher quality Full Colour specification.

Multifunction Printers or MFPs

The Multifunctional, All-in-One device combines print, copier, scanner and fax capability in a single machine. These systems are surprisingly compact and affordable. Indeed some MFPs start at prices below £200. However, in this category of printers, some hefty and powerful machines are available for Print for Pay and major corporate use, with a vast array of bolt-on systems for folding, stapling and collating documents.

Impact Printers

Rarer these days, but it is still possible to buy dot-matrix and even daisywheel devices for specialist impact applications, for example for such as multiple-copy form printing. Such printers tend to be more expensive, robust and bulky than the ink-jets and laser printers in more common use. Impact printers by definition are also much noisier in use.

Other factors - Stand-alone or Networked?

If you plan to share the printer in a workgroup on your office network, then network-ready functionality must be specified.

Speed of Operation

Businesses with a heavy output, or with a plan to share the printer among several users, a faster printer is important - and one that will avoid forcing staff to wait for printouts to get through the queue. Any shared printer is also likely to be networked so the network speed in the office is also a factor

Cost Considerations

In additional to the initial purchase cost, there is of course the cost of consumables such as ink cartridges and toner which also require budgeting. The twin costs of initial purchase (or lease) plus consumables and maintenance are defined as the Total Cost of Ownership, and requires a careful projection of costs over the life-cycle of the equipment.

Support and Supplier Backup

All printers come with a basic warranty or guarantee that entitles the purchaser up to one year return to base servicing and repairs. It is wise and useful to arrange additional cover and a service plan to suit the capacity and work-expectations of the printer.

Green Credentials

Protecting the environment is a crucial issue these days, and taking advice whilst looking for the most energy-efficient options makes sound business sense. Doing this should also save money in terms of running costs at least. Questions to ask are - What sort of power consumption and stand-by power-down features does the printer have? Is it easy to print in double-sided (duplex) mode? Can consumables such as laser drums and ink cartridges be recycled? Is the printer RoHS-compliant (The RoHS Directive and the UK RoHS regulations came into force on 1 July 2006.)? And what steps does the supplier make to contribute towards the costs of disposal under the Waste Electrical and Electronic Equipment (WEEE) directive?
