Lenovo K23 Power Adapter
The Lenovo K23 AC adapter is needed for two reasons, to charge any and all batteries and to provide a source of power for the unit. When choosing a new AC adapter, selecting the Lenovo OEM charger is usually going to be the safest choice. Because Lenovo has been known to use a single AC adapter that is probably used on other similar units, be sure you choose the right one. If you decide to buy an non-Lenovo adapter, please check on both the voltage and amperage output. A universal AC adapter is another possibility but only if necessary.
Main clues your laptop charger needs a replacement ASAP
- Battery does not charge up all the time
- Most Lenovo adapters will get warm to the touch when plugged in for 10 minutes or more
- The laptop does not run using just the AC power adapter
