Does the laptop have a direct power supply that affects the battery?

Q: The notebook from the buy back has been the power supply, no use is also, 24 hours a day is followed, the battery did not take down, I would like to have an impact on the computer?

A: When there is AC power will not use the battery, only in the AC disconnect when the battery is enabled, power off when there is a battery to protect the computer, battery life is a little shorter, but negligible. When in use, the plug on the book do not frequently pull plug, to keep the wear interface. Especially in the case of live battery, it is recommended that the shutdown and then pull. If you're only using it at home, you can remove the battery and plug it directly into the power supply, which can prolong battery life.
