Notebook battery how to repair notebook battery maintenance?

Now laptops have become a fashion, and more and more people have given up desktops and started to choose laptops. It not only has a great advantage in portability, but also takes up less space and has more integrated hardware. One of the important reasons is that the use of rechargeable batteries is one of the advantages of laptops over desktops, which can greatly facilitate the use of laptops in a variety of environments. And with the progress of battery technology, long-range notebooks emerge one after another. Today, let's talk about notebook batteries.

Introduction of notebook battery

As we all know, as consumables, notebook batteries have a long life. So when choosing a laptop, an important factor is to see if your favorite laptop battery works. So how to choose notebook battery? This question should start with the most basic notebook battery (I hope you can read it all, although it is more dogmatic).

At present, there are three kinds of batteries used in notebooks: 1. Ni-Cr battery; 2. Ni-MH battery; 3. Lithium batteries; they are generally expressed as: nickel cadmium, nickel hydrogen and lithium.

Notebook battery is composed of shell, circuit board and battery, which belongs to lithium-ion battery. Generally speaking, the cell refers to the number of cells in the battery, and mAh refers to the capacity of the notebook battery. The circuit board is mainly composed of protection circuit (or secondary protection circuit) and capacity indication circuit to manage the charge and discharge of notebook battery and its safety.

The standby time of notebook battery is mainly determined by the mah value. In general, the more batteries, the greater the mAh value and the longer the standby time. The life of notebook battery is mainly measured by the number of charge and discharge, and the quality of qualified products is generally 500-600 times. Therefore, the useful life of the notebook battery is less than 2 years, the expired battery will age, and the standby time will drop sharply, affecting the mobility of the laptop.

When consumers choose and buy notebooks, they often see parameter tables and quotations. Among them, there are only one or two parameters about notebook battery. That is, whether it is a lithium battery, how many cells. Let me tell you, the most common thing on the market now is a 6-cell ion battery. General battery life, in high-performance mode, up to 2 hours (except for those BT laptops).

Now that we know the common ones, let's talk about how to look at the parameters on the battery. Nominal batteries such as 4400mAh and 2200mAh can often be seen on notebook batteries, and the author has just said that mAh is the key to battery life. So there must be a lot of friends who think that the bigger the mAh, the better. But in fact this is not the case. The unit that really knows the capacity of the battery should be "Wh", whose Chinese name is "Watt hour". Of course, "Wh" and "mAh" are closely related to the following formula: WhV1000=mAh. It should be pointed out that the unit that measures the power consumption of electrical appliances should be power, that is, "watts".

The important parameters of the battery are composed of three parts: voltage, mAh and watt-hour. From then on, we can know that the choice of notebook battery is not "mAh", but "Wh" and the number of voltages. The author found an example from the Internet to illustrate this truth.

Ex.: the service life of the same 4800mAh lithium-ion battery is different at 10.8V and 11.1V, and this difference is due to the difference of Wh. Through the calculation, we can get the following equation:

4800100010.8 / 51.84 (Wh)

4800100011.1 / 53.28 (Wh)

It is obvious that 4800mAh 11.1V lithium-ion battery will have more advantages in battery life.

How to repair notebook battery

In fact, sometimes the battery will lose its temper, that doesn't mean the battery is broken. Here's a great way to save the battery: use the battery refresh program to restore the battery's discharge time.

Find an example from the Internet, and let's use it to teach you!

IBMThinkpad390/262650 laptops are equipped with Ni-MH batteries. Due to improper charge and discharge, the discharge time of the battery is getting shorter and shorter, with less than 5 minutes left. It is very inconvenient to go out to work with a laptop. Is there any way to restore the discharge time of the battery?

In view of the above situation, we can use the battery refresh program launched by IBM to refresh the battery so as to restore the discharge time. The specific methods are as follows.

(1) use alternating current to power the laptop. First go to FTP://fip.pc.ibm.com/pub/pccbbs/mobiles/isbr01ww.exe to download the TP390/390e/390x series notebook battery update program provided by IBM.

(2) restart the computer, press F8 to enter the startup menu and select safe DOS mode.

(3) go to the directory where the file you just downloaded is located, and execute the battery refresh program isbr0lww,exe. After reading the warning message, insert the floppy disk as required, and then press enter for self-decompression.

(4) start the computer with this floppy disk, the startup PC-DOS will appear on the screen.

(5) if you unplug the AC power supply as prompted, the program will automatically discharge the Ni-Mh battery, and after the discharge is completed, the system will shut down automatically.

(6) due to the high temperature of the battery at this time, it should not be turned on immediately, let the battery cool for a while, plug in the AC power supply.

(7) Boot the computer with floppy disk, this time Autoexec. The bat file automatically runs the refresh program and asks the user whether or not to proceed. After selecting yes, press enter.

(8) at this point, the refresh program begins to refresh the battery, which is very fast. When you return to the DOS prompt A: >, the refresh is complete.

(9) turn off the computer and charge the battery until the light turns green.

(10) repeat the above process 3 times to get the best results.

Skills of using notebook battery

After all, we now advocate low-carbon environmental protection, energy conservation and emission reduction. So you have to start with me, the following author will tell you about the tips for using notebook batteries.

Please hibernate the notebook when not in use

Do not nag the author first, this point should be taken seriously by everyone. When you don't use a laptop, let it go to sleep (it's better to turn it off!) This is not only conducive to the service life of the battery, but also a good protection for the hardware. And the way to let the notebook sleep is very simple, gently buckle the notebook. Ben would have gone to sleep very well. is it troublesome?

The brightness of the screen is appropriate.

Now so many people are nearsighted, to a large extent, it is caused by playing with the computer and watching TV. And the screen is too bright, to a large extent, resulting in excessive stimulation to the retina, resulting in pupil deformation (I am not a professional medical student, just to remind you). So, just adjust the screen brightness to suit you. After all, the most important thing in notebook power management is screen brightness. If the screen is too bright, of course, there will be more power consumption, so the battery life will be shortened.

Make energy saving settings

Desktops use alternating current, and most people may not attach great importance to the energy-saving functions of computers, but for notebooks that need to be powered by batteries, the use of energy-saving features should be paid attention to. How to design computer hardware to be more energy-efficient is not a problem for users to solve. What users can do is to effectively use energy-saving options on computer settings.

Energy-saving settings need to be adjusted by users in two places: first, there are settings about energy-saving methods in the computer's BIOS setting program; the most important thing is that there are many energy-saving settings and operations in the operating system. In the actual execution of the microcomputer system, the energy saving setting in the Windows system should take precedence over the setting in CMOS.

Let's talk about the methods of these two settings:

BIOS interface

1. Energy saving settings in BIOS

In most CMOS settings, there is a "Power Savings", in which you can select multiple options such as "Maximum Battery Life" and "Maximum Performance". "Maximum Battery Life" is the default energy saving mode setting. There are several energy saving modes for laptops, such as Idle Mode idle mode, Standby Mode standby (waiting) mode, and Suspend Mode suspension (hibernation) mode. The reason why these settings on the laptop can adjust the power consumption is that after the computer enters the energy-saving state, it shuts off some unused system devices at the right time. For example, when waiting, turn off the monitor and the hard disk; after entering the dormant state, in addition to turning off the monitor and the hard disk, you can also save the contents of memory to the hard disk, and the whole computer system basically maintains the off state. once the computer is activated or restarted, the desktop will be accurately restored to its pre-hibernation state. The energy saving setting in CMOS mainly sets the time when the Idle Mode enters the Standby Timeout of the Standby Mode and the time when the Standby Mode enters the Suspend Timeout of the Suspend Mode. Most laptops use Phoenix BIOS. Different BIOS energy saving settings may be different, and you should read the on-screen tips carefully.

2. Energy saving settings in Windows

For ordinary users, the operation of energy-saving management in Windows system may be more clear and simple. In the Windows help file, under the "manage hardware and Software" entry, there are two items related to laptop energy saving: "Managing Energy consumption" and "Managing Power on laptops" in "using laptops". You should read these before you set up Windows energy savings.

In the Control Panel of Windows, click Power Management to open the Power Management Properties dialog box. In the Power Management Properties dialog box, you should set the Power usage Plan to Portable / laptop, and reasonably arrange the options such as system wait, turn off Monitor, turn off hard disk, and so on. There will be some differences in the options that different computers can manipulate. New computers and the latest software will have more operable options. Detailed settings should be based on the functions of the computer itself and Windows help files.

Pay attention to the battery alarm

Battery alarm is now a standard feature in notebooks, so when the alarm appears, please save the file in progress immediately, or shut down immediately. This is protective for the battery.

Software monitoring is more reliable.

In addition to the built-in power management function of Windows, there are many tool programs that can monitor the status of the battery. The following is to introduce a better software for you!

PowerCenter is a power monitoring tool, only 800KB, is a software designed for laptops. In addition to showing the percentage of battery capacity, PowerCenter also shows the actual available time in hours and minutes. There are 3 ways to display PowerCenter:

(1) FullDisplay: displays details in the open window, including the use of battery or AC power, the percentage of battery remaining and the time available, etc.

(2) CompactDisplay: always appears at the top of the window in use.

(3) MinimizeDisplay: reduce the PowerCenter to the taskbar of Windows, and the information displayed is relatively simple.

PowerCenter also has a control center that can make up to six warning alerts. When the battery-drops to a certain extent, give a timely warning to the user and save the file being processed. In order not to waste power and CPU resources, PowerCenter automatically detects changes in battery status.

Regular discharge is beneficial to the "health" of batteries.

Use photovoltaic cells regularly to ensure full charging. If you need to fully use the power in the photocell, you can do this: in the Power Management dialog box, select Battery Drain, a specific power mode, and set all three Running on Batteries options to Never, so that the laptop will run continuously. Select this mode, then go to the Alarms tab and uncheck the Low Battery and Critical Battery warning check boxes (so that the machine will not enter the paused state when the battery is low). Next, let the computer run tasks that take up a lot of CPU time, such as automatically running complex 3D demonstration programs, so that you can quickly use up the remaining power in the battery, and of course don't forget to unplug the alternating current when doing these disposals.

Maintenance method of notebook battery

1. When there is no external power supply, if the card in the PCMCIA slot is not used in the working condition at that time, it is recommended to remove the card first to prolong the battery life.

2. Room temperature (20-30 degrees) is the most suitable working temperature for the battery. The operating environment where the temperature is too high or too low will reduce the battery life.

3. When using a laptop in an environment that provides a stable power supply, it is incorrect to remove the battery to extend the battery life. As far as the Asustek laptop is concerned, when the battery is fully charged, the charging circuit in the battery will automatically turn off, so the phenomenon of overcharging will not occur.

4. It is recommended that the battery power correction be carried out once every three months on average.

5. Minimize the number of times you use the battery. The number of charging and discharging of the battery is directly related to its life. Each time the battery is charged, the battery is a step forward to decommissioning. It is recommended that you try to use external power supply.

6. The battery should be removed when using an external power supply. Some users often plug in and unplug the power several times a day, and the laptop is equipped with a battery, which will cause more damage to the battery. Because every time the external power is connected, it is equivalent to charging the battery once, and the battery will naturally lose its life.

7. Recharge after the battery is exhausted and avoid taking too long to charge. Whether your laptop uses lithium or Ni-MH batteries, be sure to use up the battery and recharge it (less than 1%), which is the best way to avoid memory effects. Lithium electricity also has a memory effect, but its memory effect is smaller than that of Ni-MH.

8, precautions in peacetime use: in normal use, it is necessary to prevent exposure, moisture, chemical liquid erosion and contact between battery contacts and metal objects.
