It is important that you take good care of your laptop to keep it working well. Following these easy steps will ensure that your laptop lasts longer and requires less maintenance. As an added bonus, many of the steps will also maintain your laptop’s speed. It is also useful to do a check of the laptop once in a while to remove any errors or problems which might have crept in during the routine usage.

1.Keep liquids away from your laptop. As tempting as it might be to drink coffee, soda, water or any other liquid near your laptop, accidents can happen all too easily. Alternatively, use a cup with a cover on it, so even if it does spill, the liquid doesn’t go anywhere. Spilled liquids may damage the internal microelectronic components or cause electrical damage. Short circuits can corrupt data or even permanently destroy some parts of the laptop. The solution is very simple: Keep your drinks away from your computer. Even if you are careful, someone else might spill your drink.

2.Having antivirus software available is the best defence against a virus. Even if you know what you download, it could still contain a virus. If you choose not to have antivirus software you run the risk of a circuit error or software problem in your system. The virus may also slow down the system operations and performance.

3.Keep food away from your laptop. Don’t eat over your laptop, the crumbs can fall between the keys and provide an invitation to small bugs or damage the circuitry. Worse yet, the laptop will look dirty if there are crumbs on it.

4.Do not use your computer in a room where animals are. Their fur and hair can get into the internal workings and damage them. Also larger animals (e.g dogs) can accidentally damage them by knocking them off their support by brushing past, wagging tail, tripping over leads etc.

5.Ideally keep the computer in a clean and dust free room.

6.Protect the LCD display monitor. When you shut your laptop, make sure there are no small items, such as a pencil or small ear-phones, on the keyboard. These can damage the display screen if the laptop is shut on them; the screen will scratch if the item is rough. Close the lid gently and holding it in the middle. Closing the lid using only one side causes pressure on that hinge, and over time can cause it to bend and snap.

If you drop your cell phone in water, it is often possible to salvage it. Time is of the essence, however, so the first thing to do is to get your cell phone out of the water as soon as possible. Leaving a cell phone in water for even a few seconds might damage it beyond repair, but there are a few things that you can try and that sometimes work. The main things are opening the phone as much as possible, taking out the battery and completely drying off all of the components.

Remove the Battery

After retrieving your cell phone from the water, the next thing to do is to remove the battery immediately, without even hesitating to turn off the power. This reduces the risk of a short circuit that would render your phone useless. Dry the battery with a towel, and it set aside to dry thoroughly. The battery itself might not work again, but it can be replaced fairly inexpensively. Even if the battery does work, it is a good idea to get a new one to avoid the risk of having the old one leak battery acid.

Take It Apart

After you have removed the battery, dry off the cell phone with an absorbent towel as best as you can. Use cotton swabs to soak up water in crevices and on any fragile, exposed circuits. If you have dropped your cell phone in water, it also is helpful to disassemble it, if you can, and let all of the parts dry separately. Just be sure that you know how to put it back together. If it is a flip or sliding cell phone, leave it open to allow for maximum evaporation.

Avoid Mineral Damage

If you drop your cell phone in water that isn’t pure or another liquid, such as a beverage or in salt water, rinse off the phone with fresh water after you have removed the battery. After you drop your cell phone in water, a quick rinsing is unlikely to do any further damage, but salt, sugar or other materials might. You also could try giving your phone an alcohol bath. The alcohol will displace minerals and microscopic substances and will aid in the evaporation of the fluid. If it is available, you should use an alcohol concentration of 95 percent rather than rubbing alcohol, which usually has a concentration of 70 percent.

Let It Dry

After your phone is clean, leave it in a warm, dry area or near an air conditioner for at least three days before you attempt to replace the battery and turn it on. This is very important, because although you may think that you have thoroughly dried it, the slightest moisture can react with the battery and cause it to short circuit. Putting your cell phone in a container full of dry rice grains also can help dry it out. Make sure that the rice completely covers the phone.

Warranty Likely Voided

Unless you have insurance for your cell phone and it covers water damage, there probably is no point in sending it to the manufacturer with the hope that the warranty will cover the cost of a replacement. If you drop your cell phone in water, the warranty probably will be voided. The manufacturer’s technicians will be able to tell immediately that it has been dropped in water because of the moisture-sensitive stickers that are placed inside almost all cell phones. The best thing to do is to dry it out yourself and hope that it still works.

1.Be sure to make the brightness of your computer to the lowest setting that is comfortable. To do this, look for a purple “Fn” button on the keyboard (usually next to the left ctrl key, sometimes the key has blue lettering instead of purple). After you’ve found the “Fn” button, quickly search for another key with a purple or blue sun with an up or down arrow(usually on the arrow keys or on one of the F1-F12 keys). Now while holding “Fn” press the button with the purple/blue sun and a down arrow. (Please note some computers do not have an Fn button so if your computer does not have an Fn button in that case, just simply use one of the F1-F12 keys alone)

2.Turn off all background programs that are not needed because they take up processor space which will use more battery.

3.Check that bluetooth and/or wireless adapter is off (if it’s built in).

4.Be sure to eject any discs out of your CD or DVD drive if you do not need them. The disc will still be spinning inside and consumes a ton of energy.

5.If you are running very low on power, or are watching a DVD, your laptop may have a way to turn off the LED lights (Power light, hard drive activity light, etc.). Check your owners manual to see how.

6.Unplug any USB devices you are not using (iPods, Flash Drives, External USB mice, etc.). Many of these devices draw power from your USB port, up to 500mA (about a half an Amp) and 5 volts. It adds up quickly depending on how many you have plugged in.

7.When you are not going to use your laptop for a short time, put it into standby or sleep mode. This will only leave dire essential components in the computer running such as the memory. And allow you to resume working on your computer quickly.

8.When you are not going to be using your laptop for an even longer time, put it into hibernate(Shift+Standby Button) mode. It will have the same effect as turning the computer off, but it will allow you to go back to working on your laptop just like in standby and uses little to no power from the battery.

1

Start by turning your machine off. Unplug it, disconnect it and remove any USB wires or memory sticks.

2

For simple cleaning, tilt your laptop forward. Bang the back and hopefully anything lodged between the keys will fall out!

3

Take the end of a teaspoon and wrap it in a wet-wipe. Drag the teaspoon along all the edges of the keys and keyboard. This will pick up any dust and dirt.

4

Take a vacuum cleaner and run it over the keys. This will rid your laptop of any more dirt. Alternatively, you can use a hair-dryer to blow it away but ensure you repeat step 2.

5

If you are still having problems, remove your laptop keys. So far, we have avoided doing this because it is time-consuming, annoying and easy to get wrong.

• Research your laptops brand name and see if you do have keys that can actually be taken off
• Be careful, because the keys are often held on by fragile plastic tabs. Gently pop them off and store them somewhere safe.
• Run your wet-wipes over the bare key-board. Q-tips also work well with this, after soaking them in anything that evaporates (rubbing alcohol and hydrogen peroxide) so that you do not get moisture under the keyboard.
• Pop the keys back on. There will occasionally be keys with metal “stands” on the back – these are easy to slide back into their rails. Other keys will simply require you to depress the corners.
• You can also wash the keys, but this makes losing keys easier.

6

Finished.

Choosing the best laptop car charger is a matter of examining a few simple options and selecting the one that best suits a person’s needs. Some chargers are made for a specific brand of computer and plug directly from the car’s cigarette lighter into the back of the machine. Power adapters that convert the 12-volt direct current (DC) coming out of the cigarette lighter into 110-volt alternating current (AC) are also available. Two- or three-pronged plugs can be plugged directly into these adapters.

One option for a laptop car charger is to purchase a power cord that plugs directly from the cigarette lighter of the car into the laptop computer. Each brand of computer uses a power cord with different specifications, so it is important to select an adapter that is made to be used with the computer. This type of laptop car charger it a good option for a person looking to charge one computer or a couple computers of the same brand. These chargers will only supply one computer with power at a time.

Universal adapters that come with a set of attachments that accommodate most brands of computers are also available. Though they can charge many types of computers, they can still only power one computer at a time. A universal laptop charger or a brand-specific laptop car charger are both relatively inexpensive options.

A power adapter is another way to charge a laptop from a car’s cigarette lighter. These devises are designed to convert 12-volt DC power into 110-volt AC power. The computer’s usual charger can then be plugged directly into the adapter, eliminating the need for a laptop car charger. This is a good choice for someone who wishes to charge more than one type of electronic device from the road.

Some power adapters are made to accommodate one or more plugs at the same time. Charging two computers at once or a computer and a phone at the same time will require an adapter with at least two plugs. Computers, phones, cameras and other electronics can all be charged from a power adapter.

There are power adapters with a variety of different output levels. Reading the power requirements of the laptop is the first step in choosing the right charger. It is very important that the output of the adapter fall within the computer’s acceptable range because a lower or higher output could damage the computer. The price for power adapters ranges significantly. While price is not always indicative of quality, it’s a good idea to check product reviews to determine if a bargain adapter is worth the initial savings.

Finding the correct laptop charger is not a difficult or overly inconvenient process. All it takes is a little research. The information you need to make the right choice can be easily found on your laptop, your old charger, or on the charger to be purchased. The best part about finding the right product is that manufacturers make the choice easy. The information is usually on the charger’s case or in the description, if shopping online.

The best option in finding the correct charger for your laptop is to go to the source. Go to the manufacturer that made the computer and find the charger there. Online stores may be the best option in this case because they usually carry a greater selection than physical stores. Once at the store, look for the charger that came with your computer. This way, you will be sure to find the correct one.

If, for some reason, you are unable to go to the manufacturer’s store or are unable or unwilling to get the charger shipped to you through online stores, you can go to a computer or electronics store. When looking at the laptop chargers available, take the time to look at the computer models the charger you are looking at is compatible with. This information should be listed on the packaging. If your specific computer model is on the list, then the charger will work for you computer. If it is not, find another charger.

You can also find out what type of charger your laptop takes by looking on the bottom of the laptop. In order to ensure that you get the correct replacement parts for your computer, the manufacturer stamps product specifications (specs) on different laptop parts. There are several stamps, but you should look for the one that says “AC adaptor” or something similar. Find the model number and write it down — that is what you should be looking when buying a replacement. This information can also be found by looking at your old charger and in the documentation that came with your laptop.

You can also buy a universal charger. Again, to ensure you are getting one that is compatible for your laptop, check the product specs on the charger’s packaging. You can also be sure the charger will match your computer by making sure the specs for the charger and those for the laptop are the same. This includes making sure the voltage, input, and output are identical. Don’t forget to make sure the charger’s connections will fit your laptop.

Your desktop computer’s motherboard probably has one or more expansion card slots which you can use to add new functions, special connection ports, or powerful graphics capabilities to your computer. These expansion cards will increase the performance of your existing system.

Best Expansion Cards for PC:

Video graphics cards:

In order to play advanced PC games, run high-definition movies, or use sophisticated image-editing software on your computer, you’ll most likely need to boost the graphics processing power with a video card. Video cards take over processing 3D graphics and other video tasks, so your computer’s CPU can focus on other functions.

SCSI controller:

Your computer may not have the correct connection ports for connecting devices using the small computer system interface (SCSI), such as hard drives or certain high-speed scanners. An SCSI controller expansion card allows you to add a port for those devices.

RAID controller:

A collection of hard drives connected in a RAID configuration can share or back up data in various ways, giving you options for backing up data or increasing storage over several drives. A RAID controller expansion card gives your computer ports for multiple hard drives through high-speed connections, usually SATA cables.

USB port card:

Most desktops do have USB ports, but the version of USB they use may be too slow. You may also have more USB devices than you have ports. A multi-port USB expansion card adds high-speed ports to your computer that works faster than simple port-splitters. The latest version of USB is version 3.0, so any USB 3.0 card you install will be backwards compatible with your old USB devices and operate much faster than older ports.

TV tuner card:

If you’re setting up a home theater PC, you may want to be able to watch and record live TV broadcasts with a tuner card. Most tuner cards will include a coaxial cable connection to which you can attach an antenna or other video source. Some tuner cards will also be able to make recordings in multiple digital video formats.
