Laptop AC adapters are an important component of any laptop. Without them, users will be left without power or the ability to recharge the battery. Since AC adapters are an external part, however, they can often take a lot of abuse, leading to failure. Here we will examine some of the most common failure points for laptop AC adapter. 

Without a doubt, the most vulnerable parts of a Laptop AC adapter is it’s cables. Most designs incorporate a thin cable connecting the laptop to the transformer, and then a thicker cable from the transformer to the wall outlet. The thin cable is often the most susceptible to damage. It can get bent sharply, wrapped too tightly, or even kinked or knotted, causing damage to the cables inside. When this happens, there will often be a short in the cable, causing intermittent problems. Some Gateway AC Adapters utilize a 90 degree curved adapter plug that minimizes the stress on the connection at the laptop and many aftermarket ac adapters include this feature. In some cases, wiggling the cable will cause the adapter to work again temporarily, but it is recommended that it be replaced to avoid any risk of electric shock.

Another common failure point for AC adapters is the connectors. There is often a connector between the AC cable and transformer, and another where the DC cable plugs into the laptop itself. This connector is often fairly small by necessity and prone to damage over time as the user continually plugs and unplugs the connector. In some cases, the internal connector of the laptop can also become damaged, so it is a good idea to determine which part is defective before replacement.

The transformer is contained within the large “brick” part of an AC adapter. It is less likely to be damaged than other components because it is designed to be rugged. Nevertheless, repeated dropping or other types of abuse can sometimes cause the adapter to malfunction, and it will need to be replaced.

When you have determined that your AC adapter needs replaced, you can visit an online retailer and search for your model to find a replacement part. You can also try doing a more general search, like Dell Laptop AC Adapter or one that pertains to your brand of laptop.

Different users have different using habits in regular work so that the laptop system and Li-ion battery will perform differently from each other in many aspects. Each time after completing work on the laptop, have you unplugged the Laptop AC adapter from the motherland computer to provide it a good rest to cool down and save power energy? Actually, the radiation of the charging adapter is also very powerful if not disconnected.

Will the HP pavilion dv5000 adapter charge the lithium-ion battery and computer after shutting down? 

After shut down, the whole computer device will have a full rest without getting any power energy from external resources. As a matter of fact, the lithium-ion batteries won’t be charged after being full even though the power supply is connected with it. Of course, if the battery is not full, the charger will supply power energy to the battery after full. 

Why the plug and pin are of high work temperature even if the laptop computer is off? 

It is truth that when the laptop is shut down, the adapter is also working. Of course, the mains supply won’t reach other laptop accessories rather than the adapter itself. The self-charging has occurred to the adapter as long as the socket is connected with the plug pins. If possible, users had better disconnect HP pavilion dv5000 adapter and cool it down to maintain the whole charger in good performance to get longer lifespan. 

The dangerous influence from laptop AC adapter in radiation

As is known to all, radiation is harmful to our health while that of HP pavilion dv5000 adapter is powerful enough if users haven’t unplugged the charger when sleeping every day. Of course, it will also waste electric charge to some extent. If the battery happens to be deep discharge, users can leave some power energy inside and then disconnect it from outlet. It is unnecessary to fully charge the batteries every time.

Introduction: What is an laptop AC Adaptor?

Also referred to as a power supply or power adaptor, an laptop AC Adaptor plugs into a standard electrical outlet and converts the AC electrical current from the wall outlet to the specifications needed by the electrical device that’s plugged in. The laptop AC Adaptor is a box attached to the power cord, either at the end of the cord where the device plugs into the wall outlet, or in the middle of the power cord.

Tons of devices around your home rely on laptop AC Adaptors for their power supply. Laptops, cell phones, cordless phones, digital photo frames, compact disc players, video game systems and that just names a few.

Technology has yet to lead us to a time when laptop AC Adaptors will become universal to all electronic devices.

How an laptop AC Adaptor Works

In short, an laptop AC Adaptor converts the electric currents received by the electrical outlet into a typically lower alternating current that an electronic device can use.

Inside the laptop AC Adaptor are two wire windings that wrap around a single iron core. The first of the windings receives the 120-volt alternating current delivered to the electrical outlet, and creates an electric field in the iron core. The second wire winding turns the newly created electric field into a smaller alternating electric current. The measure of the resulting alternating current is dependent upon the number of coils in the second wire winding in relation to the number in the first winding. If the second winding is half of the first winding, the alternating current will measure half of what it did when it entered the laptop AC Adaptor. Therefore, if there were 100 coils on the first winding, the second winding will have only 50 coils.

AC/DC: The Two Electric Currents

The abbreviation, AC, stands for alternating current and is used to describe the electrical currents utilized to deliver power from power plants to homes and businesses. When graphed, these alternating currents are shown as waves that go up and down; this is because these currents do not flow constantly in one direction, but alternate directions, flowing forward and backward.

DC, which stands for direct current, describes electrical currents that flow in one direction. Direct currents are produced and present primarily in batteries, and are used mainly by devices that run by battery power.

Converting Alternating Current to Direct Current

For electronics that run on battery power, but may also be plugged into an electrical outlet, laptop AC Adaptors are used to convert alternating current into direct current. Inside the adaptor box, behind the two wire windings and the iron core are two rubber wrapped diodes that convert alternating currents into direct current by allowing them to flow in a single direction.

Traveling Abroad

Remember when traveling out of the country that you will need to purchase converters to adapt the voltage and frequency of currents to match the devices you intend to use. While residents of the United States are used to receiving currents at 120 volts and a 60 HZ frequency, residents of Ireland receive currents at 220 volts and 50 hertz frequency

There are many alternatives you can work out when it comes to purchasing a new laptop adaptor or getting an old one changed. But before you look at the alternatives available before side of you, you need to know what these equipment are generally all about.

When it comes to laptops, one of the most frustrating problems we all face is running out of battery. We may be working hard away at homework, university studies, school projects, business assignments and more, and then all of a sudden, our laptop decided to die on us, and we are left with no work, and a very bad headache. Some laptops if not constantly plugged in with a Laptop AC Adapter will lose battery within an hour or two, which is very annoying, but it is the case. There are many reasons this can happen, and some of the reasons most people don’t ever put their fingers on. Most commonly, people will think there is a fault with the laptop, so they will send it for repair, spend a lot of money, and then realise the problem has actually not been solved. Others will blame the laptop battery, replace it, and then realise that too did not work. Then they will just believe that their laptop isn’t that great unless you run it with a Laptop AC Adapter all the time you use it.

It is a good idea to use your laptop plugged in for many reasons. One reason, which is why most people do it, is that you screen will usually appear lighter, and visibility will be enhanced. Another main reason, is of course to save the battery, and keep the laptop fully charged at all times. While these are good reasons, they don’t solve the fact that when your laptop is unplugged, the battery dies very quickly. So how can you improve your laptops battery life? What is the solution when it comes to keeping your laptop on for a longer period of time, when you don’t have access to a Laptop AC Adapter?

The best way you can improve your laptops battery life is to purchase a decent Laptop AC Adapter. A high standard Laptop AC Adapter will prolong your batteries life, as when you use your laptop at home or where a plug socket is available, you will use the high quality Laptop AC Adapter, and over time the new Laptop AC Adapter will improve your laptops battery performance, enabling it to stay on for longer, when not plugged in. The only issue here is, where can you find the best Laptop AC Adapters that will meet your requirements? Most PC stores and laptop shops will stock average Laptop AC Adapters like the one your laptop came with, if you want that extra special Laptop AC Adapter, you need to find a specialist store to buy one from.

Choosing the correct laptop adapter is all a matter of voltage, output power, and proper connection. If all of these things do not match the original specifications of your computer, than a new laptop adapter will likely not work on your machine and may potentially cause a lot of damage. In the end, most replacement adapters will have a list of computers they are compatible with.

The first thing to consider for the laptop adapter is the voltage. The easiest way to check this is to turn the computer over and see if there is a voltage listed anywhere on the bottom of the machine. A sticker may be affixed with this information and other similar laptop specslisted. It should be a number with a V attached to it, such as 19.5V. This information is also available on the original adapter, if it is available.

The second thing to look for is the current output needed for the laptop adapter. This number will have an A of mA associated with it. For example, it may say something like 4.7A or 950mA. These numbers ensure that the power going to your machine will be acceptable and keep it operating within normal parameters. Not paying attention to either of these numbers could cause the electrical systems in the computer to malfunction and quit working altogether.

Once these two issues have been settled, the other important step is simply to make sure the connection fits the port in your computer where it is to be plugged in. The voltage and output current of the laptop adapter will not matter if it is not able to be connected. If ordering online or if you do not have your computer, it is advisable to check this out as soon as possible.

Many may choose the safest route possible and go with a replacement laptop adapterdirectly from the manufacturer, if available. While this is a good option, these parts may be more expensive than others that may be available from after-market manufacturers. Further, as long as the numbers match, all should work nearly the same and be just as safe and effective.

Another thing to consider is whether you want an AC laptop adapter or DC adapter. An ACadapter is made to be plugged into any standard electrical outlet such as those in a home or office. The DC adapter is made for automobile use.

Typically, laptop adapters can be found for sale anywhere computer accessories or laptop batteries are sold. Though the price will depend on the model and manufacturer, most tend to run between $40 US Dollars (USD) and $100 USD. They are also available from many online retailers as well.

An HP Pavilion laptop AC adapter has 4 important components. You should understand these things first before buying the charger. This will help you to choose correct adapter.

1. Voltage is energy per unit of charge. Choose correct voltage for your laptop. Most HP laptops have 18.5v or 19v. A 19 volts charger can be used on laptop that needs 18.5v. If possible try to get a charger that is exactly if possible.

2. Amps are another thing to consider on laptop ac adapters. Amount of current is measured in Amperes also called Amps or A. Most Hewlett Packard notebooks require 2.7A – 6A. Majority of them with 3.5 to 4.9A.

A charger with higher amps will work on a laptop that requires lower amps. For example if your laptop needs a power supply of 2.7A then a 3.5a or 4.9a will work on your laptop. But if your laptop needs a 4.9a then a 3.5a or 2.7a will not work on your laptop.

3. Wattage is another factor on the ac adapter. Watts also called as W. Watts are calculated as Volts multiplied by Amps. So W = V x A. So if your HP laptop requires 19v and 3.5a then it will be 19 x 3.5 = 66.5w. So you will need to buy a 65w charger.

Note that most of the chargers will not exactly provide Watts; you can safely buy the charger as long as Volts and Amps are matching.

A power supply adapter with higher wattage will be advisable for your notebook. For example if your computer has 18.5v and 3.5a or 2.7a then you may consider to buy 65watts adapters. If your laptop needs 4.9a then you must buy a 90watt power cord.

4. Last point to consider is connector tip that connects to the computer. HP has yellow tip or bullet pin type or Center pin type or big Yellow tip. Choose the right connector.

Before buying the HP Pavilion dv series or zv or zd or G series ac adapters get more accurate parts for your computer.

One of the biggest disadvantages with using battery powered products is that batteries have a limited lifespan. Expanding a battery’s lifespan is an area in which manufacturers of laptops, hybrid cars, and cell phones are constantly working on.

The Argonne National Laboratory recently announced that they have come up with a new way to develop lithium-ion batteries. With their latest discovery, Argonne is able to increase the battery capacity in lithium-ion batteries by up to 30%

Currently these batteries have many markets cornered, among them the laptop computer industry. In contrast with its previous counterparts, these laptop batteries tend to be more reliable as well as lighter. However, they also have a downside. Lithium-ion batteries tend to overheat and last about 750 charges, (which means your battery will last about 3years).

The new material used by Argonne would allow these batteries to be charged up to 1,500 times. This is a significant increase from 750. They accomplished this increase by creating a new compound within the battery that acts as a stabilizer.

Today’s laptop batteries use cobalt oxide electrodes. Using this electrode is the main cause for excessive heating. In order to combat the overheating issues as well as increase storage capabilities Argonne used manganese oxide.

Manganese oxide acts as a stabilizing force for a laptop battery because it contains more inactive materials that help balance out the electrochemically active ones.

This technology seems to be ideal for laptops and shows promise for cell phone use, but not quite so great for the hybrid car industry. However, Argonne is looking to expand their current capabilities to create a better power source for hybrid vehicles. In Argonne’s efforts to market this new battery they have made an agreement with Japanese company Toda Kogya.

The following statement was released by Gary Henriksen, Manager of the Electrochemical Energy Storage Department at Argonne, regarding this new deal: “Our agreement with Toda Kogyo is an important step toward bringing to market key advanced lithium-ion battery technologies that are being developed here at Argonne with funding from the U.S. Department of Energy.” He also continued to say, “The technologies being licensed will enhance the performance, life and inherent safety of lithium-ion cells compared to those that employ the cobalt-based cathode technology that has dominated the market since the introduction of lithium-ion batteries in 1990.”

The Toda Kogyo Company has been around since 1823. It is the world’s leading manufacturer of iron oxide particles. Their designs for using these particles as well as their ability to manufacture new technologies will help bring these new laptop batteries to the world market.

Currently, there is no word on how long it will take them to implement this discovery in laptops.

Last month LG Chem, South Korea’s second largest battery manufacturer, caught fire. It is estimated that this fire will trigger a large price increase on laptop battery.

The price increase will affect companies like Dell, HP, and Asus. These companies purchase most of their battery supplies from LG Chem. In total the shortfall of batteries that is likely to ensue could affect up to 40% of shipments from Taiwan.

Dell would not discuss how much prices will rise; however Dell’s spokesman Jess Blackburn was quoted as saying, “the industry is experiencing battery supply constraints because of these problems. Therefore, pricing is being impacted by current availability. But we are working with our partners throughout our supply chain to reduce the impact on our customers.”

Extra battery pack purchases may also be affected by the battery shortage. Larger battery retailers may be limiting the amount of batteries consumers can purchase.

Currently, LG Chem thinks it will be able to get its factory back to full production in two to three months. In the mean time, it will be up to other third-party battery manufacturing companies to increase production to meet the needs of the consumer.

At Priority Electronics, the fire will have little effect on our laptop battery prices. We do not purchase from LG Chem. We have other companies that produce quality laptop batteries for us. Our laptop battery prices are competitive and we offer a one year warranty. In this battery shortage think Priority Electronics as your fully stocked source for batteries

Each year, over three billion dry cell batteries are sold throughout the United States. What happens to each one of those batteries when they run out of juice? Well, that’s something that each of us needs to work on. While the recycling of laptop batteries is becoming more and more common by the day, we still have a long way to go. Here we’ve answered three very important questions that exist when it comes to the recycling of batteries.

WHY do I need to recycle old laptop batteries?
According to Adria Vasil’s book Ecoholic- 50% to 70% of heavy metals found in landfills come from our everyday batteries. That’s 50% to 70%! Because batteries disposed of in municipal landfills and trash incinerators can disperse significant amounts of heavy metals and other toxic substances into the air and water, battery waste prevention and recycling strategies are essential.

Laptop batteries make up a significant part of that 50% to 70% of heavy metals in landfills. And while most manufacturers are taking great steps in producing new types of eco-friendly batteries, it’s important to remember that laptop batteries and computer batteries should never, ever be thrown in the trash.

HOW should I recycle my laptop batteries?
It’s safe to say that most people are beginning to recognize how important it is to recycle laptop batteries and keep them out of our landfills. The easy part about all of this is that you really don’t have to much when it’s time to discard a used up laptop battery. In fact, all you have to do is contact your local recycling facility for more information on how to dispose of your used computer batteries properly.

WHERE should I recycle my laptop batteries?
As we mentioned in the previous section, you can contact your local recycling facility for more information on how and where to go about recycling your old laptop batteries. If you’re not sure just who or where your *local recycling facility is, you can try using the tools put together by Earth911.com or Call2Recycle US. These will show you where the nearest recycling center is, and they can help you from there. You also have the option of sending old laptop batteries directly to Atbatt if you would like. Take a look at the Battery Disposal Guide for more information on how to go about doing so. How to Prepare Batteries for Recycling.

Awareness surrounding the importance of recycling old laptop batteries is definitely on the rise. In the last 15 years, Call2Recyle alone has collected over 50 million pounds of batteries overall. There’s still a lot of work to be done however, and it’s on each person to make sure their old batteries are properly discarded.
