It is important to ensure that the computer is unplugged from any charging cable while working with it. Removing the battery should be the first step in removing or replacing any other part of your computer. This helps prevent injuries to yourself or to your device. There is one exception for the Lenovo IdeaPad P400 Touch: to remove the battery, you will first need to remove the keyboard by following the prerequisite guide.
