Lenovo K29 Power Adapter
When purchasing a replacement AC adapter, the actual Lenovo brand is the best one to choose. Because Lenovo has been known to use a single AC adapter that is probably used on other similar units, be certain to thoroughly note the part number that is needed for this model. A universal power adapter is a possibility if you are desperate. If your decision is to purchase a different brand charger, make note of the output of amps and voltage. The Lenovo K29 AC adapter is needed for two reasons, charging the battery and to provide a source of power for the unit.
What to see if the Lenovo power adapter is dying?
- Battery does not charge every time
- The laptop does not function while just using AC power
- Most Lenovo adapters will get warm to the touch when plugged in for any length of time
