What should I do if my laptop battery is charging?

Notebook battery Charging dissatisfaction How to do, many children's shoes are always asked small, in fact, laptop batteries need personal maintenance.

If you want your battery to be fully charged, you should set the Power management mode to "Maximum battery life".

Here's how:

Start Control Panel, find the "power" option, double-click open (as shown in Figure one). Then click the Settings button in the bottom right corner (figure II), and you can see the two power management modes (figure III) to set the battery mode to maximum battery life.

Figure One:

Figure II:

Might

The longest battery life mode is to protect the battery and prolong the life of the battery. Because of the battery life and the charge cycle, so when using this mode, when the charging power reaches a certain value will automatically cut off the battery charge to protect the battery, so the above mentioned charging is not satisfied with the phenomenon Oh ~

Laptop battery does not charge solution one: replace the electric core or the deep discharge.

If the battery is due to the problem of aging batteries, we can only take the replacement of batteries or deep discharge method to solve, but these actions can cause damage to the battery or can not be used, so be careful before you begin.

Laptop Battery Not charging solution Two: Refresh the battery with a software method.

The IBM Notebook provides a "Battery Maximiser and Power Management" software that allows us to have a good solution to the incorrect battery capacity display and short battery life. Running this software, the computer will automatically check the battery according to the status of the battery and discharge, when the end of the program can be found that the actual battery capacity and design capacity gap will be smaller (but still exist).

Laptop battery does not charge solution three: Use the Firmware method to refresh the battery.

Some manufacturers have embedded the battery correction program in the BIOS firmware (such as ASUS), we just need to enter the BIOS to perform a battery correction program when booting.

Laptop battery does not charge method four: With the self-brought program to fix battery notebook battery maintenance

1, if the strongholds has been upgraded to the Win7 system, it is advisable to use the Win7 built-in function to correct the battery, by entering the "Power Options" interface, select the "High Performance" power Plan.

2. When you click Change Plan settings, set all options under use battery to never and adjust the brightness schedule to the maximum value.

3. Click Change Advanced power settings, expand wireless adapter settings → power saving mode, and set use battery to maximum performance.

4. Expand "battery → low level battery notification" and set "use Battery" to "off". After saving the settings, close all applications and when the battery is full, unplug the AC adapter, power the battery until it shuts down automatically, and then fully charge the battery in the shutdown state.

Activation Processing:

The battery needs to be activated to handle the following conditions:

1. New batteries that have just been activated.

2. When the battery is not being used for a long time, the battery is stored at the computer and is now enabled.

3. For a longer period of time, do not use the laptop or the battery removed from the laptop for storage standby (for more than two or three months), when this battery is now enabled.

How to activate the battery:

Activating the chemical in the battery maximizes the performance of the battery by repeatedly charging and discharging the battery (fully charged, then fully discharged) three times. The so-called full charge and discharge refers to: normal power on the battery to 3% battery charge (preferably once exhausted, but also several times to consume electricity, but should not be spaced too long), and then must immediately charge the battery shutdown for 12 hours.

Here stressed the need to charge the battery immediately, because the battery even if not used will be self-discharging, when the battery power consumption to 3%, if not in time to charge the battery, self-discharge phenomenon is very easy to cause the battery discharge and damage the battery, over-discharge is a major taboo of lithium batteries.

The machine must be turned off when charging the battery for activation. If the machine waits, hangs and so on, when the green power status light is no longer beating after charging to 3-4 hours, it will automatically stop charging the battery, so that the battery can not be fully charged. When discharged to 3% power, the machine will automatically enter the sleep state, at this time should start the machine, in the process of machine startup, click on the lower left of the screen button to shut down the machine.

If the details of the above operations are well mastered, and your battery quality is not a problem, it can be very good to activate the chemical substances in the battery, maximize the performance of the battery, basically the battery in the normal use of the next time can be charged to 100%.

Notebook battery Use for a long time, often filled with dissatisfaction, and even show damage, it must be used to pay attention to a few tips: Whether your notebook use lithium or NiMH, as far as possible to the basic exhaustion of electricity after recharging (less than 5%), this is the best way to avoid the memory effect. In fact, lithium-ion batteries have a certain memory effect, just a lot smaller than NiMH batteries. However, it should be noted that when charging, try to avoid too much time, general control within 12 hours.

The life of the battery is not determined by the total use time, but by the number of charge and discharge. If the battery is always loaded into a notebook without taking it off, the battery will not remain fully charged as expected, even after turning off the machine and removing the AC power. The laptop battery is power-hungry even when it shuts down the computer because it integrates a control circuit into the battery. As soon as the AC power is plugged in, the battery will start charging and the battery will recharge and discharge repeatedly when the power is turned on or off, affecting battery life.

Many books have built-in battery correction tool, in the Lenovo Sun C461m Notebook, for example, if the use of more than two years, battery life is only less than 40%, this time with the use of the Lenovo Precision Correction tool, can restore battery life to more than 80%. For Lenovo Old notebooks, it is recommended to upgrade the new version of the Power management software, and then the battery charge until it is not charged.

1. Double-click the Power Management icon on the taskbar, and select "Maximum battery life" mode.

2. After clicking the Settings button, switch to the Battery Care Settings page, click the Start button, then a prompt window pops up, please close all application processes, and ensure that the AC power adapter is connected, after clicking the "Continue" button, the battery accuracy correction is being processed.

3, to wait patiently, the battery status will show "Power is on, not charging." When "Battery accuracy correction complete" pops up, click the "Confirm" button and the battery status will show "Power is on and charging", indicating that the battery calibration was successful. When fully charged, you will find that the battery life has been restored.

Laptop Battery Not charging method VI: Using third-party software to correct the repair method of battery notebook battery

What if the laptop does not have a built-in battery correction tool? Use the Batcal software to correct the battery at this time. To the author of the BenQ S42 notebook For example, after two years of use, battery life is only about 50%, when connected to the AC adapter, the battery can not be charged until.

1. Run the Batcal tool and click on the "Set Slow Discharge" button to select the slow discharge mode.

2. Click the "Begin Calibration" button and the Power Options window will pop up, and it is recommended to select "Portable/Pocket" mode and set all items under the usage scheme to "never".

3, the screen saver is also closed, click the "OK" button, then you will be prompted to discharge, after the discharge, will pop up a prompt window, prompting you to unplug the AC adapter, when the battery is completely exhausted, the system will automatically shut down, and then plug in the AC adapter normal charging. If you want to quickly discharge, you should choose "Fast discharge" mode, while the screen brightness to the highest, and in the discharge process can not operate the notebook.

Laptop Battery Not charging method VII: Fix the battery in the notebook

To make it easier for the user to fix the battery, some books will integrate the battery correction tool in the BIOS with the Asus A6ja Pen as an example.

1, first to charge the battery, to ensure that the normal boot, when the boot press F2 key to enter the BIOS setup interface. Switch to the Power menu, set the LCD powersaving option to OFF, or turn off the display power saving mode.

2. Position the cursor to the "Start Battery calibration" option and enter the battery level proofing prompt interface when the carriage returns, ensuring that the AC adapter is plugged in.

3, wait for a period of time for the battery to charge (Figure 6), when the screen appears "please remove AC adapter" information, indicating that the battery is full. Then unplug the AC adapter so that the laptop continues to power up until it runs out, the battery will shut down automatically when it is discharged, and then the AC adaptor will charge.

Laptop batteries are consumable items. Notebook best plug in the battery and the use of power, the battery is to be plugged in, or it is easy to burn the motherboard, suddenly power loss is also easy to damage the hard drive and data, I was a professional notebook repair, low-level mistakes I have committed. Listen to me, that's a lot of things I've touched. and the battery separate issue also has, because the battery will have self-power, when below a certain voltage, the battery chip will be locked, this is for safety reasons, the battery will be scrapped. Lithium battery heat is more dangerous, need to find out why, so as not to explode. You put the electricity completely once, life is short once, the total estimate is about 500 times.

Workaround One: Use the Software method to refresh the battery.

The IBM Notebook provides a "Battery Maximiser and Power Management" software that allows us to have a good solution to the incorrect battery capacity display and short battery life. Running this software, the computer will automatically check the battery according to the status of the battery and discharge, when the end of the program can be found that the actual battery capacity and design capacity gap will be smaller (but still exist).

Solution Two: Use the firmware method to refresh the battery.

Some manufacturers have embedded the battery correction program in the BIOS firmware (such as ASUS), we just need to enter the BIOS to perform a battery correction program when booting.

Solution Three: Replace the electric core or the deep discharge.

If the battery is due to the problem of aging batteries, we can only take the replacement of batteries or deep discharge method to solve, but these actions can cause damage to the battery or can not be used, so be careful before you begin.

Battery is a "consumable", the degree of battery loss depends on the correct operation of the battery, operating mode, operating frequency, working environment temperature, inventory time (for unused batteries) and other factors.

1. Battery charge and discharge times directly related to battery life, the general lithium battery charge and discharge times only about 400~600 times, improved products are only more than 800 times, every time the battery is charged to the end of the use of a step forward. (When charging a battery below 85%, it will be recorded and the number of times to charge is increased.) To this end, when the battery voltage is greater than the battery management program set the starting value of 96%, and you are currently located in a 220V AC power supply, should try to use AC power, try to reduce the number of battery charge, in order to prolong the battery life. The battery does not have to be removed from the machine because it does not charge more than 96% of the battery at boot time. But even so, if you are using AC power for a long time and rarely use batteries, it is better to move the battery away from the machine, as the heat generated during the long run of the notebook will cause some damage to the battery.

2. When the power is 3~5%, the battery should be charged in time, otherwise the self-discharge of the battery will cause over-discharge and damage the battery, the machine can be shut down at the time of charging, hang and so on any state, can also be used for edge-filling. Charging must be filled at once, otherwise it will damage the battery. such as charging when the machine shutdown or hibernation, when charging to 3-4 hours after the green power status led no longer beating, at this time the power has reached 100%, should promptly unplug the AC power plug to prevent the battery caused by charging and damage the battery. If the machine waits while charging, hangs or side-charging state, the battery will automatically exit the charging state when the green power status indicator no longer bounces after charging to 3-4 hours. Charging process will be a quick charge, then the Power status indicator is yellow (solid), charged to a certain value after the trickle into a thin current slow charge, then the power status indicator color becomes flashing green; has been filled with 100%, it turns green (solid). Lithium battery Charging process is a constant pressure mode, the start of charging soon after the voltage will stabilize, and the current is getting smaller.

3. Do not charge the battery before it is completely exhausted (that is, the power is in 5-100%), otherwise it will shorten the battery life. The battery should be used when the battery is 5~95%, so the battery will be charged when using the AC power adapter (side charging state).

4. When the battery is 96~100% or the battery has been removed from the machine, you can use the AC power adapter to start the operation, using AC power adapter, please first plug the AC power adapter DC output plug into the machine, and then plug the AC power plug into the 220v~ socket; When removing the AC power adapter, unplug the AC power adaptor before unplugging the AC power adapter's DC output plug from the machine. Failure to do so may cause damage to your device. When using an AC power adapter, when the AC power plug is plugged into the 220v~ socket, and the power status light on the machine is not lit before (note: about 5 seconds in between) Please press the power button to turn on in time, when the computer shuts down or enters hibernation, except for the green power status indicator, all the LEDs are off. Please unplug the AC power plug from the 220v~ socket in time, the AC power plug is unplugged for about 5 seconds, and the green power status indicator is off; (if required, the DC output plug of the AC power adapter can not be unplugged from the machine and the battery will not reverse-discharge through the AC power adapter.) Otherwise, the battery will be charged and damage the battery. The battery is charged because the AC power adapter is still in a non-unloaded state due to shutdown. Do not unplug the AC power plug from the 220v~ socket if the machine is paused to wait or suspend, since the machine still needs to be powered on. (It is recommended not to keep the machine waiting or hanging for a long time to take care of your machine.) )

5. If the battery is not used for a long time (several months), it should be removed from the machine and saved. It is recommended that the battery be discharged and recharged every 1.5 months or so to improve your battery status to increase battery capacity.

6. If the battery is not used for a long time, it should be set to 30~50% after storage, it is recommended to charge the battery once a year, and set its power to 30~50%, in case of excessive discharge and damage to the battery. How to set the battery charge to 30~50% is: when the battery charge is greater than 50%, the power can be powered up to 30~50%. If the charge is less than 30%, then power up to 3%, then charge to 100% and turn on the battery to 30~50%.

7. Do not put the battery in high temperature and cold environment, the battery performance will be temporarily reduced. The battery that holds the standby state and storage state should be placed at a lower temperature where the optimum temperature range is approximately 10~20摄氏度.

8. For the adjustment of the charging start value set the charging start value, click the Power Plug icon in the system tray (when you use AC power on) or the large white battery icon (when you use the battery boot)/select improvebatteryhealth/ Modifies the value of the Startchargingwhenbelow. Do not intentionally drastically change the charging start value set in the battery management program for extended charging cycles, because when you set the charging start value low (for example, 80%), the "charging cycle" of the AC power adapter with the battery may take up to three or four months, but if the battery is used, it must be reactivated again, Otherwise, the battery's status and capacity are poor. This instead increases the number of charges and shortens the battery life. Furthermore, the battery needs to be discharged and recharged every 1.5 months or so, and the extended recharge period after the starting value of the charge (e.g. 80%) becomes meaningless. The battery is fully charged due to self-discharge phenomenon and the power down to 96% generally lasted about 50 days or so, and the battery just about every 1.5 months or so to perform a discharge and charge finishing, it seems that IBM for our pre-set charge starting value of 96%, is justified. However, with the aging of the battery, when the battery is fully charged due to self-discharge phenomenon and the amount of time required to decline to 96% may be shortened, it is necessary for us to reduce the starting value of the charge slightly, so that the time is just about 1.5 months.

9.IBM in the ThinkPad notebook computer related data in the technical indicators of the "battery life" is determined by the manufacturer under specific conditions, the indicator in our normal use of notebooks under the conditions are not attainable, for example: the relevant information in the technical indicators of the "battery life" For 4 hours, we can only get about 3.5 hours of battery power supply in normal use. If the difference is very far, and is still in the warranty period, please contact the news quickly. I was the Lenovo notebook is such a problem, I tried it, first remove the computer battery, plug in the adapter, you can boot normally, then the computer is good. If the computer does not turn on, I decided that is the computer motherboard problem, because the motherboard is the power to connect each hardware platform, so I get customer service, detection problem is the motherboard burned out, repair, one weeks, get the computer, normal operation. (Warranty period, free) if the battery is broken, it's only changed. Batteries need to be put down often, about 1-2 months to charge and discharge once.
