What problems should be paid attention to in the use of laptop batteries

The improved product is only more than 800 times, and every time the battery is charged, it takes a step towards the end of use. (When charging a battery with a battery capacity of less than 85%, it will be recorded and the number of charging times will be added.) For this reason, when the battery voltage is greater than 96% of the charging start value set in the battery management program, and you are currently in When 220V AC power is available on site, AC power should be used as much as possible to minimize the number of times the battery is charged to extend the life of the battery. At this time, the battery does not have to be removed from the machine, because the battery with a capacity greater than 96% will not be charged when the machine is turned on. But even so, if you are using AC power for a long time and rarely use the battery, it is better to remove the battery from the machine, because the heat generated when the notebook is running for a long time will cause some damage to the battery. But it should be pointed out that in this case, once the AC power supply is cut off, your unsaved data will be lost due to the lack of battery support. This gain and loss must be carefully weighed by the user. 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. When charging, the machine can be shut down, suspended, etc., or it can be used while charging. . The charge must be fully charged once, otherwise the battery will be damaged. This is based on preventing the shortening of the battery life due to the shortening of the charging cycle and the number of new charges; it is not due to memory characteristics. Unlike nickel-cadmium batteries and nickel-hydrogen batteries, lithium-ion batteries have memory characteristics, and lithium-ion batteries do not have memory characteristics. If the machine is shut down or dormant while charging, when the green power status indicator no longer bounces after charging for 3 to 4 hours, the power has reached 100% at this time, and the AC power plug should be unplugged in time to prevent overcharging the battery. Damage the battery. If the machine is waiting, suspended or used while charging, the battery will automatically exit the charging state when the green power status indicator no longer bounces after charging for 3 to 4 hours. During the charging process, fast charging will be performed first. At this time, the power status indicator will be yellow (steady on). After charging to a certain value, it will switch to a trickle current for slow charging. At this time, the color of the power status indicator will become flashing green. ; After it has been full 100%, it becomes green (steady light). The charging process of lithium-ion batteries is a constant voltage method. Soon after charging starts, the voltage will stabilize and the current will become smaller and smaller. 3. Do not charge the battery before the battery is completely exhausted (that is, the battery is between 5-100%), otherwise the battery's life will be shortened due to the shortening of the charging cycle and the new charging times. When the power is 5~95%, you should use the battery to work. In this case, use the AC power adapter to charge the battery (charging and using state). 4. When the power is 96~100% or the battery has been removed from the machine, the AC power adapter can be used to start the operation. When using the AC power adapter, please plug the DC output plug of the AC power adapter into the machine first, and then connect the AC power source Plug the plug into the 220V~ socket; when removing the AC power adapter, you should first unplug the AC power plug and then unplug the DC output plug of the AC power adapter from the machine. Otherwise, it may cause damage to your equipment. When using the AC power adapter, when the AC power plug is plugged into the 220V~ socket, and the power status indicator on the machine has not ignited (note: during about 5 seconds), please press the power button to turn on; turn off or enter During sleep, after all the indicators except the green power status indicator are off, please unplug the AC power plug from the 220V~ socket in time (not later than 5 seconds), about 5 seconds after the AC power plug is pulled out, green The power status indicator goes out; otherwise, it will overcharge the battery and damage the battery. Because the AC power adapter is still in the non-removed state in the shutdown state, the system's power management program and the interface circuit composed of the power management chip in the battery will automatically switch to the shutdown charging state after about 5 seconds to charge the battery. (If necessary, do not unplug the DC output plug of the AC power adapter from the machine. At this time, the battery will not be reversely discharged through the AC power adapter.) If the machine is in a waiting or suspended state due to the suspension of work, do not plug it from the 220V~ socket Unplug the AC power plug; therefore, the machine still needs to be powered. (It is recommended not to keep the machine in a waiting or suspending state for a long time to take good care of your machine.) 5. The battery life indicated by IBM in the technical indicators of ThinkPad notebook computer related materials is the manufacturer's specified conditions It is measured that this indicator cannot be achieved under the conditions of our normal notebook use. For example, the battery life indicated in the technical indicators of the relevant information is 4 hours, and we can only get about 3.5 in normal normal use. Hours of battery power supply. If the difference is far, and it is still within the warranty period, please contact IBM as soon as possible.
