Do you know anything about laptop batteries?
Laptop battery is the battery in the laptop, now using rechargeable battery is one of the advantages of laptop compared with desktop computer, it can greatly facilitate the use of laptop in various environments.
The earliest batteries were nickel-cadmium (NiCd) batteries, but they had a "memory effect" and had to be discharged before charging, making them inconvenient to use. It was soon replaced by Li-ion batteries which had no "memory effect".
For just bought a new laptop, because the charge for the first time after the manufacturer's test, and battery should be with 3% of the battery when the phone is switched on for the first time, don't immediately use external power supply at this time, but the remaining 3% of the electricity to shut down, and then use the power converter charging, don't boot up while charging, charging time must be more than 12 hours, until it is full of (e.g., after a full charge to unplug the power adapter, then one-time will run out the battery again after filling, repeated three times, in order to activate the most potential of the battery.
In daily use, you should try to reduce the number of battery, because the battery charge and discharge times is limited, each charge, the battery life is reduced, so if in the use of an external power supply, battery should be removed, if often plug power supply many times in a day, and a notebook with batteries, greater damage to the battery, because each time an external power supply connection is equivalent to recharge the battery.In addition, notebook batteries have a memory effect, part of the charge (less than 100%) will lead to the battery cell's chemical performance is inconsistent, so the battery performance will decline, so be sure to use up the power before charging (less than 1% of the power), this is the best way to avoid memory effect, otherwise the battery is very easy to temporarily lose power.Three, correct discharge method notebook battery use time is long, often appear charge dissatisfaction, even show battery damage, such as standard battery life could have reached 4 hours, but the battery life after charging less than 40 minutes, as long as the battery can be restored to discharge.Disable the system screen protection first, and then enter the "power options" attribute interface, set the "power plan" to "high performance", then click "change plan Settings", all will be under the "battery" option is set to "never", finally into the "advanced power Settings" battery alarm prompt, such as power less than 5% of the police.
At this time the screen brightness to the top, make sure all the closed after the program window, and save all the data before work, after confirm the battery is above 80%, unplug the power supply and all external equipment discharge, discharge after the laptop will be automatically shut down, then the power plug in to laptop batteries, this process can be repeated 2 ~ 3 times, its purpose is to keep the battery, small current discharge and the discharge status in our daily use is impossible to achieve, its effect and discharge for the software.If there is no alarm operation function, power management properties at this time we need to use the highest intensity of artificial discharge operation, the method is to turn Off the power supply into the BIOS Settings management functions, the "PowerSwitchMode" set to "Off", because many laptop computer has a power-saving mode, when there is a low power automatically shut down, restart the notebook after save Settings, press the PAUSE key before enter the system remain in Windows picture, until the battery runs out and shut down, and repeat 3 times can be recharged after.
Under the condition of the battery power, and sometimes we are dealing with important documents, if the battery is power off suddenly, how embarrassing it is one thing, serious still can cause significant loss of data, but the laptop will be provide power management software, it is often also provides alarm function, allows users to set when the battery is low and the insufficient power to remind them.ThinkPad laptop's built-in power supply manager, for example, the user to run this software, you can in the global power Settings window click on the "enable battery power shortage alarm", and then set the battery goes down to a certain time period (for example, 10%), while only 10% battery life, the system sends out the alarm to remind the user to save the data as soon as possible, in order to prevent the electricity is notebook computer suddenly loses power, undermine unsaved work.
Laptop batteries belong to consume parts, using time and discharge, the more its battery life and life is short, to do this for business users, daily maintenance for the laptop battery is also very important, the ThinkPad power manager provides the battery data view and maintenance functions, in the battery information window, here will display the battery state of health, voltage, temperature, keep the information such as capacity, residual time, charging times, so that the user is reasonable for routine maintenance, such as health show in red, that the battery life will soon expire, please replace the battery in time,The yellow color indicates that the battery is partially aged and should be noticed by the user.Special mention charging times, many users for the sake of convenience, sometimes in case with batteries used connect the power adapter, and plug in the ac will automatically recharge the battery every time, this happens, the more it means the battery, the more severely reduces the service life of the battery, in order to carry out the battery discharge and user software provides the function of the battery charge and discharge limits, method is to point "battery maintenance" button, and then under the "charging valve" choose "custom", can be set at this time when to let the battery charge and discharge, such as don't want to remove the battery because of trouble,You can set the "start charging below" value to less than 10%, so that the battery will not be charged even if connected to an ALTERNATING current.
Battery can't be charged:
This problem is mainly due to the power management mode setting. The user may set it to the longest battery life mode. In order to protect the battery and extend its service life, the battery charging will be automatically cut off when the battery charging capacity reaches a certain value to protect the battery.
1. Click "Start -- Control Panel -- Power supply".
2. In the power on selection, click the Settings button in the middle of the lower right corner.
3. At this point, you can see two power management modes and set the battery mode to the longest battery life.
