A built-in DVD burner and a wide selection of ports, including a USB Type-C connector, make this a very versatile computer.

What screen size do you want?

No Preference

10 to 12 inches:  The thinnest and lightest notebooks around have 10 to 12-inch screens. However, you may sacrifice keyboard size for portability. Many laptops in this class double as tablets.

13 to 14 inches:  Provides the best balance of portability and usability. Laptops with 13- or 14-inch screens usually weigh between 3 and 4.5 pounds.

15 inches:  The most popular size, 15-inch laptops are the least expensive and provide plenty of desktop real estate. While most 15-inchers are easy to take from room to room, some are on the bulky side.

17 to 18 inches:  If your laptop stays on your desk all day, a 17- or 18-inch system will likely provide everything you need for work and play. Many gaming notebooks are in this size category.

10 Ways To extend the battery life of your laptop

       10 Ways To extend the battery life of your laptop

     There is nothing more annoying than a laptop that showing “Low Battery”. Usually it is not a hardware fault, but the weakening battery of the notebook. We have 10 tips on how to extend the life of your laptop while using the laptop.

1.Regular defragmentation

Defragmenting helps your hard drive work faster, regular defragmentation can make the hard drive to maintain efficient state. The quicker the mocing hard drive works lesser is the load placed on the buttery.So ,your battery can last longer

2. Low the screen brightness

Most of the computer's screen brightness can be adjusted, there are some can even reduce the CPU operating frequency. In the use of battery, reduce these parameters can be more effective to extend the battery life.


3.Shut down the programs background

 There are some programs running in the background, although they can not directly see the operation of these procedures, but are in the consumption of CPU processing power, of course, also consumes the battery power. The best way is to close all the unnecessary procedures in the background, in order to extend the battery life.


4.Reduce the peripheral equipment

USB devices (including your mouse), Wi-Fi wireless connection can consume the battery energy, when the equipment is not in use, it is better to pull out or shield out.

5.Add more memory

 More memory means that the notebook does not have to go over the virtual memory. Virtual memory is built on the hard disk, obviously access to memory power consumption is low, so more memory than the hard disk, can reduce power consumption.


6.Empty the CD/DVD Drives 

Even if you don’t intend to use it,don’t leave any CD/DVDS as leftovers in the drives.A spinning drive sucks battery power like a sponge.


 7.Keep the pin clean

Here we suggest that every few months to clean up the battery metal touch pin, you can use the cloth soaked with alcohol. This can ensure that the battery inside the power, can be more effectively transmitted to the various components to consume.

8. Exercise your battery

"Do nothing" to stay for a long time. Once charged, you should use it at least once every two or three weeks. Of course, do not let your lithium battery completely run out  the power, to keep the battery away from memory effect .

9. Hibernate instead of sleep

When your laptop goes to sleep, it uses a small amount of power to power its RAM and keep its system state loaded in memory, allowing it to wake up and resume in just a few seconds. When your laptop hibernates, it saves its system state to disk and powers off, using almost no power.

If you’re not going to be using your laptop for a few hours, place it into hibernate mode rather than sleep mode to conserve even more battery power. Sleep mode doesn’t use a lot of battery power, but hibernate uses as much as having the computer powered off.

10. Reduce operating temperature

  Reduce the temperature of the laptop can make it works more efficient . Using for  a  long time notebook, the internal will accumulate lots of dust, which may make the          notebook internal working temperature rise. Regular cleaning the notebook out of dust is important to extent the life of battery. 

Misconceptions about laptop batteries

                   Misconceptions about laptop batteries

      For everyone to correct the mistakes in the comparison of  laptop battery capacity, let's list several kinds of bad habits in the process of using laptop may seriously hurt the battery to see if you have the trick?

1. Do not install the battery to use the laptop

The thickness of the mainstream laptop is getting smaller, the battery also uses a built-in non-replaceable design, so the best unplug the battery when plugging in a laptop computer has basically disappeared. However, this argument is very common in the era of battery replacement, the author also found in university dormitories, not willing to install the battery using a laptop a lot of classmates. So what's wrong with this habit?

First of all, the battery is a fragile product, for the sake of protecting the battery, and unplug the battery when plugging in the laptop, this argument is not wrong. It shows that such people are very care for things, and nothing bad. However, if the battery is not used for a long time, you need to charge the battery approximately half of the charge (why is half the power? The following floor 47 users gave a detailed explanation), and need to charge the battery from time to time, otherwise if the battery is placed For too long, long-term in the absence of electricity may also hurt the battery, until you think of it when used, it is likely to appear fully charged condition. Batteries may be discarded when they are not in use, and unplugged laptops from batteries will lose their defense against power outages. Important information on running is lost and accidental power loss may damage the hard disk. On the whole, the installation of batteries to use laptop outweigh the disadvantages, it is recommended that you use the laptop or do not remove the battery.

2. often do not plug in the laptop

In addition to some of the great care of the battery reluctant to use friends, and very convenient to a class that is hard to use the user's computer batteries, I do not think the power cord, and wanting to work often use laptop battery, low battery alarm until the system was reluctantly inserted On the power supply, in fact, the use of these two types of extreme users, are harmful to the battery.

As mentioned earlier, the battery is a consumable, as long as you use the battery alone when the battery will be depleted. In general, there are limits to the number of lithium-ion batteries that can be used in the design cycle. A single charging cycle means that the battery is completely depleted but does not necessarily mean that the battery is charged once. For example, one day you might use your laptop for an hour or more and recharge it after using half the battery. If the next day is still the case, it can be counted once (rather than twice) charging cycle, therefore, to complete a charge cycle may take a few days.

So the number of cycles the battery is often used levels of computer use is an important reference factors such as the author of the MacBook Pro battery has cycled 131 times, for almost two years using a laptop, it is a relatively light Degree of use. The actual use of the battery capacity will increase with the use of the number of cycles and become smaller, which is why the longer the battery life, the shorter battery life reason. The actual size of the battery capacity, can reflect the health of the battery. For example, the author's laptop battery health is 7859/7981 = 0.98, which is 98%.

Therefore, if you often do not plug in the long-term use of laptop computers, will undoubtedly increase the number of cycles of the battery quickly to speed up the process of battery depletion, the battery life will be shorter and shorter, but will greatly reduce your laptop When selling second-hand price.

3. Use the laptop in high temperature environment

Lithium battery operating temperature is limited, in general, the operating temperature of lithium batteries are generally between 0 ℃ -40 ℃, below this temperature will lead to a drastic reduction in battery life, but the damage to the battery is not too Big. However, if the battery temperature is higher than the limit, it will rapidly exacerbate the battery loss. If the temperature is too high, it can cause serious consequences such as battery explosion.

In short, the battery is very afraid of heat. Therefore, when using the laptop in the summer, remember not to let the computer overheat, do not use the laptop in a hot environment, try to use the air-conditioned room. Otherwise, not only the battery is easily damaged, the internal components of the computer are also likely to malfunction。

On the contents of the laptop battery will be introduced to everyone here. Do not know whether we now know how to compare different battery capacity, whether to get rid of the bad habits of using laptop batteries? If you have any questions or suggestions, welcome to the comments in the column below, I will promptly answer for everyone.

Can you remove my laptop battery to extend its life?

     Can you remove my laptop battery to extend its life?

some people remove the laptop battery  before running computer.because they want to preserve her laptop battery. Should they remove it before running the computer on AC power?

Doing so is probably the best practice, but it's a hassle that most people, including me, don't want to bother with. My laptop spends most of its time plugged into AC power, with a fully-charged battery inside.

  Heat from the running computer can shorten the  laptop battery life. For that matter, the heat from the battery doesn't do the computer any good, either. And depending on how smart your laptop is about power issues, it may be draining and recharging the laptop battery as it runs--which could further wear it out.

    That's why the best possible practice is to work most of the time on AC power with the battery out. Then, a few hours before you plan to run the PC off the battery, shut down the laptop, unplug it, put in the laptop battery, plug in the AC power, and let it charge for a few hours. But really, who's organized enough to do that?

    So here's what I recommend: If your laptop is likely to remain plugged for the next week or more, shut it down, remove the battery, and stick to AC power. (You should never remove or insert the laptop  while the laptop is on, even in sleep or standby mode.) However, if you use it unplugged with any sort of frequency, keep the laptop battery in.

   There's something else to consider: If you live in an area with frequent power outages, the laptop battery is also protecting you from sudden crashes caused by loss of power. In that situation, you may want to keep the laptop battery in--or invest in an Uninterrupted Power Supply (UPS).

   Generally speaking,the laptop battery is very important for the laptop,we must take car of it.

How to do if your laptop “ plugged in but not charging”

How to do if your laptop “ plugged in but not charging”

Sometimes, you connect the AC adapter but getting any juice. What’s the matter and what is to be done about it?There are several reasons and how to solve the problem.

1. Replace the Battery

Remove the battery and then plug it in and try to power it on. That way, if it turns on, you know there's (at least temporarily) a good connection between motherboard and DC jack, the problem is likely a bum battery.

2. Examine the cord

Examine the entire length of the power cord for teras,dents,  and worn-down insulation. If you notice any, or if the power brick is warped or smells like burnt plastic, the cord is probably faulty. You'll need to purchase a new cord for your laptop.

3. Check the Connector

Inspect the connection. If the cord's attachment to your laptop wobbles or feels loose, there could be a problem with the connection. Unplug the cord, remove debris with a wooden toothpick, and remove heavy dust build-up with compressed air.

4.keep the computer cool down 

If your laptop battery feels very hot, excess heat could be interfering with the charging process. Turn off the computer for several minutes to cool down. If you haven't cleaned your laptop vents recently, blow a can of compressed air into the fan vents, to remove some dust.

5. Check Your Settings

For Windows Laptops: 

Check your power settings. Go to Start → Control Panel → Power Options. There may be a "low battery level" setting at too high a level, which can cause your computer to shut down instead of charge.  For example, if you set the computer to shut down when the battery level drops too low or set the low battery level at too high a percentage.The simplest way to deal with these settings is to restore them to the default.

For MAC Laptops: 

Check your energy settings. Open Systems Preferences from the Dock or your Applications folder. Click on Energy Saver and check both the "Battery" and "Power Adapter" setting tabs. In rare cases, a sleep setting set too low can look like a battery charging issue. 

6.Power management software in Windows Vista

Understanding battery charging issues
If the laptop does not indicate that the battery is charging, the most likely that the battery itself is operating correctly, but its power management software may have become corrupt. In order to solve the problem, you need to uninstall and reinstall the power management software by using the Device Manager. Those steps will explain how to uninstall and reinstall the ACPI Battery listings in Windows Vista, and how to obtain and install updated BIOS files, if needed to correct other battery issues.

1. Click Start and type device in the search field, then select Device Manager .
2. Expand the Batteries category.
3. Under the Batteries category, right-click the Microsoft ACPI Compliant Control Method Battery listing, and select Uninstall .
WARNING: Do not remove the Microsoft AC Adapter driver or any other ACPI compliant driver.
4. On the Device Manager taskbar, click Scan for hardware changes .
Alternately, select Action > Scan for hardware changes .
Windows will scan your computer for hardware that doesn't have drivers installed, and will install the drivers needed to manage your battery's power. The laptop should now indicate that the battery is charging.
