protect your IBM laptop battery
When you are using the IBM notebook battery, something you need to know to protect your battery. Some mistake of operation detail may damage your battery unconsciously.
Now we will give you a example to analyze, and explain the importance of the importance of "operation detail".
If the notebook are using alternating current, after shut it down, when should we pull out the alternating pin?
After we shut down the notebook, the screen will close later, and we will think the notebook has been shut down successful, so we may immediately pull out the pin, but i will tell you it's wrong. Of course the screen was closed, but the main board indicator light is still loud, and this mean your computer is still working, in other words your computer is still need power supply, so if you pull the pin out at that time, the notebook will immediately switch from alternating current to battery current, using battery for a second for no reason, this may not using too much power, but can accelerate the battery decline into the start charge electric quantity, so it will shorten the battery's charging/using period, shorten the battery's life. So it's wrong we pull it out too early, how about pull it late? When the main board indicator light closed (but the power light is still bright), if you did not pull out the pin, the system's power manager program and the Interface Circuit Chips will auto switch to "shut down charging" status, so after shut down and don’t pull out the pin will charging your battery, if your battery was still have >96% power, this will hurt your battery.
So, the correct operation is: except the power light, when all of the light below screen has been closed, please pull out the pin (don’t delay for 5 seconds), after you have pulled out the power about 5 seconds, the power light will close by itself.
