Features to be considered before buying cheap laptops

Processor of the laptop: A processor is very important to run applications and to perform on-screen tasks. The processor should not be less than 1.4 GHz as it may affect the quick performance of the laptop. For day today operation using word processing, e-mail, spread sheets etc the above processor speed is enough. When Pentium processors are bought they assure a longer battery life and at the same time they are quick.

Screen size of the cheap laptops should not be less than 12.1 inches. The screen size of laptops is measured diagonally. The larger the screen size, the higher the resolution, making it easy for viewing more information all at once.

Laptops should have a good battery life as they are carried with the operator for presentations, or for calculations whenever and wherever they are required. A laptop with a good battery life should be able to perform jobs ranging from 3 to 7 hours of non stop work without any electrical charge required in between. Lithium ion rechargeable batteries are an ideal choice.

The hard drive capacity is very important to store large amount of data on to the laptops. A cheap laptop can be chosen with a hard drive capacity ranging from 20 GB to 40 GB depending on the person’s usage.

The keyboards of laptops are different from those of the desktop computers. The keys on the keypad are relatively smaller and are packed closely with each other. Hence, it is very important to see if it can be handled comfortably before purchasing a cheap laptop.

Touchpad or pointing stick inbuilt with a laptop can be more very useful than a mouse connected via USB port. Two USB ports are more than enough for a cheap laptop; in case more ports are required the user can use an external USB hub.

The ideal weight of the laptops should be between 4 – 10 pounds, never go for a more weighing laptop even if it comes for a very cheap amount. In order to reduce the weight of the laptops, external CD drives can be used. For communications a built in Ethernet port is more ideal than the serial ports or infrared ports.

Types of Desktop Memory Configurations For Desktops

A computer memory is one that retains the data for the computer for a certain period of time. RAM, CD, DVD, Hard disk are all part and parcel of the computer system. These devices are used mainly for storing the data from the computer. Here again, all these items differ in the capacity and in the storage speed.

The CPU – Central Processing Unit will be connected to the main memory of the computer. The programmes and the data that are used currently or that are run currently in the computer will be stored in this main memory. But, the present era of computers do come with the RAM-Random Access Memory and a solid state memory. These devices are annexed to the CPU with the help of the memory bus. Memory Bus is otherwise called as the address bus.

In some computers, cache memory is available along with the RAM. This cache memory will possess minute chunks that are going to be used by the CPU immediately. This is installed mainly to cut short the time of fetching and in turn increase the working speed of the CPU. Thus the function of the CPU is increased by the working of the cache memory. Commonly, RAM is considered as the very vital part of the computer memory. It is made up of the integrated semi conductor chips.

The RAM can be compared with the other types of memory. The main feature that brings out RAM from the other kinds of memory is that RAM can be located from any location of the computer with the same speed. Some types of RAM chips are very capricious. Thus these RAM chips drop all the data when the power supply is off. Some of the computers are provided with the Shadow RAM which helps in copying the present data and makes the computers work very efficiently.

Earlier, the computer cost was on the very high side and hence the end users of the computer always desired to upgrade it rather then going in for a new one. But now the scenario is completely different due to the decrease in the rate of the hardware and the interest is increased to change the computers than upgrading them with the parts.

Exchange of computers is economical only in the case of home users and not in the case of high end computer users as replacement of servers is still found to be very costly. Hence for these cases, it is better to replace the computer with the desired spare parts to update the computer.

The memory is available in the market in different configurations. For laptops and desktop computers, it ranges from 128 MB to 120 GB. This capacity will be sufficient for the regular usage. More memory is required when the computer is equipped with more programmes. In these cases, it is not advisable to buy new computers and rather the same can be upgraded with the available slots for internal expansion.

How to care for your batteries to last longer?

Because of the high failure rate of fleet batteries and the uncertain situations such failures create, some organizations assign a person to maintain batteries. This person checks all batteries on a scheduled basis, exercises them for optimum service life, and replaces those that fall below an accepted capacity level and do not recover with maintenance programs. Batteries perform an important function; giving them the care they deserve is appropriate.

A personal user is one who operates a mobile phone, a laptop computer or a video camera for business or pleasure. He or she will most likely follow the recommended guidelines in caring for the battery. The user will get to know the irregularities of the battery. When the runtime gets low, the battery often gets serviced or replaced. Critical failures are rare because the owner adjusts to the performance of the battery and lowers expectations as the battery ages.

The fleet user, on the other hand, has little personal interest in the battery and is unlikely to tolerate a pack that is less than perfect. The fleet user simply grabs a battery from the charger and expects it to last through the shift. The battery is returned to the charger at the end of the day, ready for the next person. Little or no care is given to these batteries. Perhaps due to neglect, fleet batteries generally have a shorter service life than those in personal use.

How can fleet batteries be made to last longer? An interesting contrast in the handling of fleet batteries can be noted by comparing the practices of the US Army and the Dutch Army, both of which use fleet batteries. The US Army issues batteries with no maintenance program in place. If the battery fails, another pack is issued. Little or no care is given and the failure rate is high.

The Dutch Army, on the other hand, has moved away from the open fleet system by making the soldiers responsible for their batteries. This change was made in an attempt to reduce battery waste and improve reliability. The batteries are issued in the soldier’s name and the packs become part of their personal belongings. The results are startling. Since the Dutch Army adapted this new regime, the failure rate has dropped considerably and, at the same time, battery performance has increased. Unexpected down time has almost been eliminated.

It should be noted that the Dutch Army uses exclusively NiCd batteries. Each pack receives periodic maintenance to prolong service life. Weak batteries are systematically replaced. The US Army, on the other hand, uses NiMH batteries. They are evaluating the Li-ion polymer for the next generation battery
