How can I find the correct replacement charger for my ThinkPad?
Asked by

I bought a second-hand ThinkPad that came with a charger that may not be original. The label showing its voltage and wattage has been removed, and the connection has become loose, so I need to replace it. How can I find the correct voltage, current, and wattage for the laptop without relying on the missing charger label?

A USB-C charger is only an option if that particular ThinkPad supports charging over USB-C. Some relatively recent models still use a proprietary charging connector, so confirm that feature in the laptop’s specifications first.

Look up the exact ThinkPad model number and its official charging requirements. The laptop’s specifications should tell you the correct voltage and the minimum current or wattage, which is more reliable than trying to identify the damaged charger.

The original charger might not have been the right one, so don’t use it as your reference. Search using the full laptop model number and verify the connector type, polarity, voltage, and wattage before buying.

Check the label on the bottom of the laptop, near the battery compartment, or around the charging port. It may list something like 20 V and 2.25 A. The replacement should match the voltage exactly and provide at least the required current. A higher wattage rating is generally fine if the voltage and connector are correct.
