In fact, the laptop's lithium battery in the "light / charge" the number of times is limited, all the use of light recharging will only greatly shorten the battery life. At the same time, the battery should be more dry place to charge, in addition to pay attention to heat problems, which is the enemy of the battery.

The battery is full or the charger is pulled out as well
Q:Is the power adapter too high to hurt the notebook?
You are assured that this is no problem, if this is the output of the current is too large, it will hurt the books, but this is the input current is too large is no problem, we are the production of this, this situation We are very understanding, do not believe you can look at my Baidu name, my Baidu name is equal to my career, if you really have a problem, you can come to me, I can send you one free of charge.
