Which component is often checked or replaced when a laptop is not charging?

RAM Module
AC Adapter
Hard Drive
Cooling Fan

The correct answer is: AC Adapter

When troubleshooting a laptop that is not charging, the AC adapter is often the first component to check or replace. The AC adapter is responsible for converting wall outlet power into a form that the laptop can use to charge its battery. If the adapter is faulty, damaged, or not providing the correct voltage, the laptop will either not charge at all or may charge intermittently. In many instances, users may not realize that a problem with the AC adapter is the cause of their charging issues, especially if the laptop still powers on when connected to the AC supply. Checking for physical damage, ensuring that the connection is secure, or testing with a different adapter can often resolve the problem. If the laptop works with a new or verified working AC adapter, then it confirms that the original adapter was at fault and needed replacement. Other components like the RAM module, hard drive, or cooling fan generally do not affect the charging process directly. While issues with these components can lead to other performance problems, they wouldn’t prevent the laptop from charging unless they cause a complete failure of the device.
