I found out that when battery is in and then the adapter is plugged, the adapter shuts off (output voltage gradually drops to 0), and the only way to restart it is to unplug it from AC power and plug it in again. Personally I wouldn't risk it. If, as you say, the power cord is short there's a good chance it'll come out during the operation anyway.
When you use a laptop computer close to a power outlet, plugging in the AC adapter to power the laptop is a good practice. Your laptop battery takes advantage of the power outlet and saves the battery for situations when there is no power outlet available.
It will work but when it has an internal battery that means the internal battery also acts as the real time clock battery which keeps system time. So if you remove AC power you will reset to default time and lose BIOS settings. So unless you want to leave the laptop on 24/7 I recommend getting a new battery. Was this reply helpful? Yes No
Some of this is true for ALL Lithium-ion batteries. However, you should NOT unplug the battery when fully charged. Every time you unplug the power and use it on battery, you degrade the battery; they are only good for a finite number of charges.
Your laptop battery takes advantage of the power outlet and saves the battery for situations when there is no power outlet available. While using the AC adapter to power the laptop, you can leave the battery connected to the laptop. There is no need to remove the battery and keeping it in has benefits.
Removing the battery from a laptop is only necessary if you need to do a hard reset or when replacing internal hardware. Other than that, the battery should always stay inside the laptop. Like all battery-powered devices, if you plan on not using the laptop for over a year, it is a good idea to remove the battery.
