Buy a new laptop battery, how to use and he said AC power: what do you mean I should plug or unplug after charging in use if there is my first full electric shutdown or direct plug on the line of laptop do not know who can help me
Due to the power of the family is generally about 100V-240V (alternating current, referred to as AC), the power car and aircraft are generally about 12V (DC, referred to as DC), but the three common power supply is not stable, not for the laptop computer direct charging, otherwise it will damage the battery and laptop computer. Laptop power demand for stable constant voltage direct current.
The notebook AC power supply (AC) is the AC DC power supply. Now all the external power sources of the notebook are AC DC, or also called the charger and transformer.
The working principle of laptop power adapter is simple: it is the power of instability by using the principle of switching power supply circuit into a DC voltage by the conversion of notebook computer needs to the notebook computer power supply and charging.
The battery in the notebook battery was completely used up.. Then enough for 12 hours.. This allows expansion of the battery's internal capacity.. Repeat this 3 times later.. Basically just fine.. Notebooks can be plugged into batteries.. If you worry about a power failure and cause a power failure, the file is lost..Many of my friends don't use batteries.. Only external power supply.. That way, you need to keep your laptop batteries in good order.. The battery needs to keep 50% of the electricity.. Use it at least once a month.. It's better to calibrate the battery..In fact, the current battery is full of AC power after it is plugged in.. The laptop battery doesn't power.. After 3 full discharge charging.. Just use it..
