Lenovo K4350A Power Adapter
If you decide to buy an non-Lenovo adapter, please check on both the volts and amps outputs. Because Lenovo uses one power charger that can be used on other units, be certain to thoroughly note the part number that is needed for this model. The Lenovo K4350A AC adapter is needed for two reasons, to charge any and all batteries and to provide a source of power for the unit. A universal power adapter can be used if you are desperate. Upon choosing a replacement AC charger, choosing the Lenovo brand one will probably be the safest way to go.
Main clues your power adapter is failing
- Most Lenovo AC adapters can get quite warm when plugged in for 10 minutes or more
- The laptop does not work while solely using the AC adapter
- Battery does not charge whatsoever
