A laptop’s battery is the component that provides power to the laptop when it is not connected to an external power source, such as a wall outlet or a docking station. A laptop’s battery can wear out over time, losing its capacity and ability to hold a charge. This can cause the laptop to not turn on or shut down unexpectedly when it is not plugged in .

According to some web search results , some signs and symptoms of a failing laptop battery are:

•The laptop does not turn on or turns off suddenly when it is not connected to an external power source

•The laptop shows a low battery warning or a red X over the battery icon even when it is fully charged

•The laptop takes longer to charge or does not charge at all

•The laptop feels hot or the battery bulges or leaks

To fix this issue, the technician should replace the laptop’s battery with a new one that is compatible with the laptop model and specifications. The technician should also dispose of the old battery properly, following the environmental and safety guidelines .

Reinstalling the laptop’s operating system, enabling a remote desktop account, or issuing a peripheral set for use in the conference room are not effective solutions for this issue, since they do not address the root cause of the problem, which is the faulty battery. Reinstalling the operating system may erase the user’s data and settings, and it may not improve the laptop’s performance or power management. Enabling a remote desktop account may allow the user to access their files and applications from another device, but it does not solve the problem of the laptop not turning on. Issuing a peripheral set for use in the conference room may provide the user with an external monitor, mouse, and keyboard, but it does not guarantee that the laptop will work without an external power source.
