A laptop or notebook is equipped with a battery, so you too can work without direct power available. The maximum useful life of such batteries is quite different for each notebook and also depends on how you handle it himself. Here you can read about various features of the battery of a laptop.
Operation of a rechargeable battery
Put simply stores a rechargeable battery, as in a laptop is power when it is charged, and shows them off when there is no other power. How the process of charging and discharging takes place, determines to a large extent the lifespan and battery life. If you have a device that has a rechargeable battery purchases, then there are always exactly how to deal with the battery. Life after these instructions to prolong your enjoyment of the battery to have.
Guidelines for using your laptop's battery
As already suggested, is there a good guide to the battery and charger to be present, stating how it is best to use and charge for as long as possible to profit from them. One is the battery life itself, so how long it will last and also the battery life when the notebook to provide power where no normal power supply available. A number of general interest are also:
* A battery remains the most optimal work when it is fully charged, after being fully discharged first.
* For most batteries is advised that this is before they actually put into use, first two or three times the cycle of fully charging and fully discharging to continue.
* Almost everyone leaves the bat-in the laptop, but when you work with regular electricity is much better to remove the battery from your notebook here. When you let down because the battery, the process of charging and discharging of a degree place, and this reduces the load on the battery life and their life.
* Just when you rarely have to work with your laptop without power is present on the battery so you are notified, it is advisable to occasionally aware of the laptop battery to work. This will improve the lifespan and battery life for the better again.
* Make sure the battery is always around empty space, so it does not overheat.
Battery life of your laptop
A battery has a finite life, the maximum time that your laptop can work when no flow is present. This is useful depends on the capacity of the battery, but also as said before the way you deal with it. When you're working on your laptop and gets energy from the battery, then you can use that time period extended by the energy of the laptop at a lower level to. In the settings of your laptop you'll find several ways your laptop temporarily to a lower energy to set up without your work during your hindrance. You can also buy or download special software that allows other software that uses lots of energy, turns off when you battery power, such as Windows Vista Battery Saver.
Buying a battery for your notebook
How long the battery charger or your laptop just last depends on many factors, such as how often you use it, how you use and the quality of the battery itself. There can come a time when the battery as it were, and you must replace it with a new one. It is always recommended to an original brand and type on the laptop belonging to replace it. This also applies if you half to buy spare battery to work longer when there is no power available.
The technology of today skyrocket. The computers are getting better, smaller and ever cheaper old. Of course you want along with the time and the time to buy a new computer. But buy a desktop or a laptop? What is right for you?
Desktops
What is a desktop
A desktop is a normal computer you on, under, beside or close to your office move. The computer cabinet is connected to a separate monitor and other peripherals needed.
When is this useful?
A desktop PC is useful when you need a computer for a certain place. A desktop is hard to move. If you still want to move, what is possible, you should disconnect all cables, and everything moved individually.
If not?
It is very awkward when you no fixed place for your computer and it still would have to move. For example if you have a computer for work and home, if your house is updated constantly, or if you have no fixed home.
Laptop (notebook)
What is a laptop
A laptop is a small computer that you can fold open and close. The upper half is a built-in screen, and in the lower half (on the desk) is a keyboard. Everything is so in a package and is easy to carry.
Where is this prudent choice
If you travel a lot and want to take your computer is a laptop handy. Because this laptop bag is an easy to do, it's no problem to wear them. This way you can have all your files and keep up with everything.
When a laptop is not "if you sit in a fixed position, not a laptop you should buy. You can also fine with a laptop sitting in a fixed location.
If not?
If you really sure that your computer never moves, and good performance to go in terms of video card and memory, is more convenient to buy a desktop that are cheaper.
Price
Desktops are generally cheaper if you compare the price and performance. A desktop with a good video card (= especially needed for games) is cheaper than a laptop with the same video card. Because in a more desktop space and the parts may be greater, there is less work needed to get it agrees. It is therefore logical that in a laptop more work and smaller parts (expensive) are.
Short
When a desktop
* You have a permanent place
* You will find better performance for less money
* You do not mind having a computer case stand
When a laptop
* You travel a lot
* You always want everything at hand
* You want something compacts.
To purchase a new computer technical knowledge seems almost a requirement. Without any knowledge of computers and the contents of a computer will be many vendor can easily foist the most expensive computers. Therefore it makes something on the inside of a computer to know, so you know where to look. For those who are totally not interested in computers, this can still be useful when purchasing a new PC.
Desktop or laptop?
First, on the purchase of a computer, a choice between a desktop or a laptop. A desktop is usually seen as a "normal" computer with screen, keyboard and mouse sit separately. One advantage of a desktop is that all parts separately to replace. One advantage of a laptop is a laptop that you're very flexible. A disadvantage of a laptop is that no parts to replace.
Fortunately, this choice for most people still own it.
Parts of a Computer
A computer's processor will form the heart of the computer. It gives instructions and signals to various parts of the computer. When choosing a processor let you include the manufacturer. Today there are two dominant manufacturers in this market, namely Intel and Advanced Micro Devices (AMD). Processors from both manufacturers are basically the same in functionality. People actually pay for the difference in brand and speed of the processor. In general, AMD processors are a better value for money, given AMD a little less known than Intel. In addition, the clock speed is important. This indicates how fast the chip can process instructions. One should also note the system bus, chipset and motherboard. The processor itself is in fact part of a chipset, which is placed on the motherboard. The chipset consists of a number of chips that together are responsible for performing functions related to audio or video.
A good video card is important if one computer to buy newly released games to play or to use the computer for video or photo editing technical. Most video cards that come standard on desktops, will meet the requirements of normal computer use, such as email, internet, watching films and occasionally a (simple) game. However if recent games, it is advisable to have a better video card separate from the desktop to purchase and there (have) put. If you buy a laptop, it is important to choose a laptop stand has built a good video. This is a laptop which is very difficult to retrofit. Usually we buy a laptop's not, if one aims to use the computer for games or heavy editing.
It is also important to pay attention to memory. Memory splits into temporary memory and memory Permanently. Temporary memory is RAM (Random Access Memory) is mentioned. RAM uses the computer as temporary storage for programs and documents you at the time of computing uses. The amount of RAM memory is also important for the speed of your computer. Permanent memory is used for programs, documents and storing the operating system. This happened on the hard disk drive. It is important to check the capacity of a hard disk drive, for example, especially if you plan to download many movies.
Finally, it is a wise choice if you own CD's and DVD's to burn or you prefer to others late. Because a computer must have a CDR / DVDR drive. This is a CD tray or any other media files on a CD / DVD can burn.
System
As for the OS is not really a choice. With most Windows computers 7 shipped. If you buy an Apple-branded computer, then there is an operating system on computers that Apple's own included.
A new computer
Once you have a new image that your computer must meet, it's 'only' a matter of choosing a store. Through the Internet price comparison sites are enough to find. It is advisable to use them, prices of computers can vary considerably from store to store. Good luck!
When you build a computer, or buy, it is important that the computer is working properly. A stable running PC starts with a good ATX power supply. This PSU (power supply unit) is 230 volts AC from the proper voltages that your computer needs, and that is at most 12 volts. You understand that such a piece - for most people unimportant - hardware has a lot to endure. Many computer problems are therefore by a malfunctioning power supply.
What does the computer power supply?
A feed is an important function namely: the conversion of AC (Alternating Current) to DC current (direct current). It is a variable AC power source, which must be converted to be used in a computer. The components in a computer using a similar flow: DC current.
There are different types of feeds available, active, passive and water-cooled power supplies.
If you rondsnufflet internet you see that much difference between the ability of the various power supplies. Starting at 300 watts and as high as 1000 watts. And the price is!
What to look when buying food?
The parts for the 12 volt rail to provide more amps are more expensive than the other voltages. Buy a cheap power supply bijvoorbeel 650 watts, then the 5V and 3.3V often with a fair amount of amps, unfortunately that is not the place where it comes, whether at the 12V connections, which the video card (s) and other stroomslurpers with power.
When you buy a proper diet, has at least 24 amps, but preferably 30 amps on 12 volt connections. May be desirable that the example 2, 12 volt connections with 1x 10 and 1x or 2x 15 amps 15 amps
The number indicates how many amps that supply at that voltage ballast (rail) can handle. The power to the power supply is indicated, the total sum of all the different amps to track, but can be converted to watts
Voltages
A fed 220 or 230 as input for what a large part to the motherboard. This only happens after it is converted from AC to DC. The hard drives, video card and optical drives get power directly from the power supply (12 volts)
The motherboard will have the following voltages:
* +3.3 Volt
* 5 Volt, usually for components
* 12 Volt, modern devices such as video cards that use a lot of power, but also for fans.
* -5 And -12 volts. This is rarely used. The -5 volt power supplies often come up in modern any more.
* 1.0 has a connector for ATX motherboard with 20 pins.
* ATX 2.0 is a connector with 24 pins. This is needed for an Intel LGA775 socket. Often feeds in addition to the connection of an additional 1.0 ATX 12-volt connection for the ATX 2.0 standard. This cable you prick alongside the cable into the motherboard.
Many modern power supplies have one or more S-ATA power connectors. There are also separate adapters to get from the standard 12-volt plugs a plug to s-ata.
Power works best around 50% of their maximum capacity. If you average power consumption of your system has, therefore do well to a power to procure one of the double handle. And the maximum power consumption of your system will set them cope with the efficiency it has, so pull in some extra margin is sometimes needed.
Of particular importance is the efficiency of the power supply. The best power supplies out over 90% efficiency, cheap generic copies, perhaps 70-75%. Power not converted is actually thrown away, and the difference between 10% and 30% of the current used disposal is great, especially if you have heavy systems. It is therefore of great importance to the nutrition info at the right to review or to the manufacturer's website in advance to find.
Faulty power supply? - Computer problems!
The 12 volt power to "all the basic components of a computer. When there is shortage amps on the +12 V in order to feed the various components, it can be challenging.
1. The computer is regularly
Usually this happens for example after installing a new video card or hard drive / optical drive. The power supply is overloaded .. Install a heavier diet will solve the problem.
2. You hear a loud bang and smoke coming from the diet
The food, the capacitors 12 volt power jumped. The damage is often limited to food.
3. You hear a bang and smoke coming from both power from the computer
The capacitors of the 12 volt power outlet in the food jumped, along with several components that were connected to it. Often the motherboard, processor, memory and video card is defective.
Grounding
Besides a good diet is a good socket with a precondition. From my own experience, excellent computer or hardly working at a poor or non-grounded outlet.
The computer can be on his ass get the PC fails, restart, for example, but there is nothing on the hard drives. That this is, is because of static electricity, normally through the earth into the wall is removed. Now that accumulates with many problems as a result. Several parts in this computer can malfunction.
Power connected but the computer does not do anything?
You have connected to the connector for the motherboard, but you may be the 12 volt socket on the motherboard password?
