IBM Thinkpad Pocket book Battery Maintenance.

IBM laptop battery, account activation procedure, due to various reasons, often in information of the operation on the error, unconsciously inadvertently injure your battery. Here we convey a detailed analysis of a couple examples to illustrate the "operational details" in the importance of IBM notebook battery maintenance. Example One particular: When the laptop AC power with the state, shutdown, unplug the AC plug could be when? Finished off work before too long screen off, then you're able to think that success have been shut down, then quickly unplug the AC select readily, Although the screen won't know that off, nonetheless board power indicator (a circle while using Z-appearance of light) remains to be kindle, laptop in fact still working right this moment, that machine needs to supply right this moment, if this unplug the AC plug as soon as notebook from AC energy immediately to battery-powered Situation status, no reason to use the battery a while, although if this will never take much power, but raise the battery more quickly fell on the set initial charge limit value, thereby reducing the battery charge aided by the cycle, affecting the mobile computer battery life. No HVAC plug is pulled returning, pulling the night and then? When board power indicator light turns off (power guage still kindle), if certainly not unplug the AC stopper, the system's power managing program and battery contained in the battery management chip interface circuit consisting of about 5 seconds will automatically turn "off express of charge", so really do not delay after shutdown are going to be no reason to grab the AC plug on the power> 96% of the battery for some days of charging, and injure your battery. [Battery not fully depleted before (ie electricity from 5 to 100%), not to charge the battery, otherwise it will shorten battery life. To sum up, the correct action is: in addition to power lights outside the bottom of the screen all the lights off, unplug the AC plug that with (not later than 5 seconds), AC plug from about 5 seconds after the power indicator automatically turn off. According to the analysis, the original AC power supply, the intention is to minimize the use of batteries to extend laptop battery life cycle, and defects due to operational details, "operational details" of the importance of the Thinkpad laptop battery maintenance evident. Example 2: When using the AC power supply, plug the AC adapter AC input and DC output plug (unload) the operational details of the order is luxurious. IBM laptop battery maintenance of the correct method of operation is: first AC adapter DC output plug into the laptop's power jack, then plug into the 220V AC input AC power outlet, and should be removed when the first AC input Unplug and then pull out the DC output plug. If the plug (unloaded), the reversed order, the AC adapter will be at no-load condition, the AC adapter is not allowed at no-load status, because of their work in the pulse state, no-load transformer windings inside the switch will produce very high peak voltage breakdown, such as anti-IC, capacitors and other voltage-sensitive components. Although the current AC adapter has been equipped with its no-load protection circuit inside, but the design should take into account other problems, this protection circuit protection is very limited, therefore when the AC adapter at no-load condition when may be damaged. From the above analysis we can understand, Thinkpad laptop battery maintenance of any details of the operation is so important, does not allow for vague and sloppy, that's bigger, which is what we usually talk about the careful nature of science and technology . To this end, I feel the need to write down some of the previous rules for the operation of the text on the battery to make appropriate changes, finishing for your reference, to draw attention to the details of the operation, but also criticized the corrections and additions please. Laptop battery activation process: following the battery needs to be activated to deal with: 1 has just opened a new battery. 2 for a long time do not use batteries, storage batteries away from the computer at the state, are re-enable this battery. 3. A long time without using a laptop or notebook computer out of storage from battery backup (for more than two or three months), when the battery is re-enabled. Laptop battery for activation of processing methods: Activate the chemicals inside the battery to maximize battery performance through repeated charging and discharging of the battery (fully charged and then fully discharge) three times. The so-called full charge and discharge is: normal battery power so the battery power to 3% (preferably once depleted, can be divided into several times to power, but not interval too long), and then must immediately shut down the battery charge twelve hours. This emphasized the need to immediately charge the battery, because batteries can also be used, if not self-discharge, to 3% when battery power consumption at this time if not in time to charge the battery, the battery self-discharge phenomenon can easily cause over-discharge The damage to the battery, lithium battery discharge is a big taboo. Activation of the battery charging process, the machine must be turned off at. If the machine at this time to wait, hang-up state, when the charge to 3 to 4 hours after the green power indicator is no longer beating, the machine will automatically stop charging the battery, so can not fully charge the battery. When the discharge to 3% of the electricity, the machine will automatically enter sleep mode immediately, you should restart the machine, the machine starts the process off the bottom left of the screen, click the button, so that the machine shut down. If that's all good grasp of detail and the quality of your battery no problem, you can very well activate the chemicals inside the battery to maximize battery performance, basically a normal battery after each use can charge to 100%. Laptop battery should pay attention to the problem: The battery is a "consumables", battery consumption depends on when you use the battery for the correctness of the operation, the operation mode, operating frequency, ambient temperature, storage time ( of unused batteries) and other factors can affect IBM laptop battery maintenance. 1 notebook battery charge and discharge directly to the laptop battery life, battery charge and discharge is usually only 400 to 600 times, improved product, but 800 times, on one charge the battery on the end to the use of forward step. (When the 85% of electricity to charge the battery, will be recorded and to increase the number of times a single charge.) End, when the battery voltage is greater than the battery management program set in the starting 96% charge, and you currently live place a 220V AC power, AC power should be used to minimize the battery charging to prolong battery life. At this point the battery does not have to move away from the machine, because the boot will not charge more than 96% of the batteries. But even so, if you are using AC power with little long-term use of batteries, it was suggested to remove the battery from the machine to be better, because the long-running laptop heat generated when the battery will cause some damage. It should be noted, in this case once the AC power off, you will not save the data support the absence of cell loss, this was a failure, the user must carefully weigh. 2 When the power is 3 to 5%, it is timely to charge the battery, or battery self-discharge phenomenon will cause over-discharge damage to the battery, charging the machine and may shut down, suspend any other state, can also be through charging . Charge must be a full, otherwise it will damage the battery. This is based on the reduced charge with the cycle to avoid the increased number of charge cycles and reduces the battery life, and not because of "memory feature" issue, lithium batteries do not like the nickel-cadmium batteries and nickel-metal hydride batteries have "memory feature" lithium batteries do not have "memory characteristics. " Such as charging the machine at shutdown or hibernation, when the charge to 3 to 4 hours after the green power indicator is no longer beating, the battery has reached 100% at this time, the AC power plug should be removed promptly to prevent overcharge and cause the battery damage the battery. Such as charging the machine at the wait, hang, or through charging state, when the charge to 3 to 4 hours after the green power indicator is no longer beating, the battery will automatically exit charge state. Charging process will be carried out in fast charging, yellow when the power status indicator (Always), filled to a certain value into the Juan thin current slow charge, then the power indicator flashes green color becomes , has been filled with 100%, you turn green (Always) a. Lithium battery charging process is the constant pressure approach, and began charging voltage that will soon stabilize, and the current is getting smaller and smaller. 3 battery is not fully depleted before (ie electricity from 5 to 100%), not to charge the battery, otherwise it will reduce the charge to increase with cycle number of charge cycles and shorten battery life. When the power of 5 to 95% when on battery, so when using the AC power adapter will charge the battery (through charging state). 4 When the power of 96 to 100% or the battery removed from the machine can be switched on using the AC power adapter, AC power adapter, please use the AC power adapter DC output plug into the machine, then the AC power plug into the 220V ~ socket, remove the AC power adapter, unplug the AC power plug should then unplug the machine from the AC power adapter's DC output plug. Otherwise you may damage the equipment. When using the AC power adapter when the AC power plug into the 220V ~ socket, while the power status indicator on the machine yet, gave the first (Note: during about 5 seconds) please press the power button on, off or sleep, in addition to the other outside the green power indicator lights are extinguished all, please unplug from AC 220V ~ power plug (not later than 5 seconds), AC power plug pulled out after about 5 seconds, green power status LED is off, otherwise the battery will overcharge and damage caused by batteries. Turned off due to the AC power adapter is still not remove the state of the system's power management program and battery inside the power management chip interface circuit composed of about 5 seconds will automatically turn "off state of charge", the battery charge. (If necessary, from time to unplug the machine from the AC power adapter's DC output plug and the battery will discharge through the AC power adapter reverse.) Suspended so that if the machine into standby or suspend state, not from 220V ~ Unplug the AC power plug, so when the machines still need power to maintain. (Not recommended for a long time to make the machine into standby or suspend state to care for your machine.) 5. IBM ThinkPad notebook computers in the technical specifications of the relevant information in the marked "battery" is the manufacturers are measured under conditions specific to the target using a laptop in our normal conditions can not be achieved For example: information marked in the technical specifications of the "battery" for 4 hours in normal use, we can only get about 3.5 hours of battery power supply. If you are very far, but still under warranty, Please contact the notebook battery vendors..
