Lenovo ThinkPad T420S Power Adapter
Due to the fact that one Lenovo adapter is probably used on other similar units, be certain you select the correct one for the ThinkPad T420S model. The Lenovo ThinkPad T420S AC adapter is responsible for two things, charging the battery while simultaneously providing power for the laptop. If your decision is to purchase a different brand charger, please check on both the volts and amps outputs. A universal power adapter is a possibility if yours is unavailable or backordered. When purchasing a replacement adapter, the actual Lenovo brand is the best one to choose.
Clues the power charger needs replacing ASAP
- The unit will not function without the battery installed
- Your Lenovo battery refuses to charge up at all
- Most Lenovo adapters get warm when plugged in for 10 minutes or more
