IBM laptop batteries in use, activate and other operations, for various reasons, often in the details of the operation error, unconsciously inadvertently hurt your battery.

Here we give a detailed analysis of two examples to illustrate the "operational details" importance.

Example One: When the laptop AC power status of office, shut off, when to unplug the AC plug? Work completed shutdown, then, turn off the screen, then it is easy to think that success is turned off, then immediately unplug the AC plug conveniently, does not know at this time although the screen closed, but board power indicator (a circle with the word pattern of light Z) still kindle, laptop in fact still working at this time, that machine then the power supply needed; If this unplug the AC plug when the notebook from AC power immediately to battery-powered Status status, unjustified use of a few seconds the battery, although if this does not take much power, but speed up the battery more quickly fell to the set initial charge capacity value, thereby reducing the battery charge with the cycle, affecting the battery life. No AC plug pulled back, pull night will do? When the board power indicator light turns off (power light still kindle), if not unplug the AC plug, the system's power management procedures and battery inside the battery management chip interface circuit composed of about 5 seconds will automatically turn "off state of charge", so do not pull off the exchange after the delay would be no reason to plug on the power> 96% of the battery for a short time to charge, and hurt your battery. [Battery not fully depleted before (ie electricity from 5 to 100%), not to charge the battery, otherwise it will shorten the battery life. ]

Above, the correct action is: in addition to the power indicator light outside the bottom of the screen all the light has gone out, that is, unplug the AC plug with (not later than 5 seconds), AC plug for about 5 seconds, the power indicator Auto off.

According to this analysis, the original AC power supply, its intent to minimize the use of the battery, thereby extending battery charge with the cycle; the details due to operational deficiencies, "Ai Qing Qing is not actually anti-harm"; "operational details" The importance is evident.

Example Two: When using the AC power supply, AC adapter AC input and DC output plug plug plug (unload) the details of the order of operations is luxurious. The correct method of operation is: first AC adapter DC output plug into the laptop's power jack, then plug into 220V AC input AC power outlet; and unloaded when the AC input should be first Unplug and then the DC output plug. If the plug (unloading), the reversed sequence, the AC adapter will load the state Department, the AC adapter is not allowed to empty state office, because of their work in the pulse state, no-load switch inside the transformer winding will produce very high peak voltage breakdown, such as anti-IC, voltage-sensitive components such as capacitors. Although the AC adapter it has established its no-load protection circuit, but the design should take account of other problems, this protective effect of the protection circuit is very limited; therefore no-load state when the AC adapter when Department may be damaged. laptop battery
