Lenovo M4400S Power Adapter
Upon choosing a replacement AC charger, the actual Lenovo brand is the best one to choose. If you decide to buy an non-Lenovo adapter, it is imperative to note both the volts and amps outputs. Because Lenovo uses one power charger that is probably used on other similar units, make sure you check the part number for the correct one. A universal power adapter can be used but only if necessary. The Lenovo M4400S power adapter has two main uses, to charge the onboard battery while simultaneously providing power for the laptop.
Major indications your power adapter is dying
- Battery does not charge all the time
- Most Lenovo adapters will get warm to the touch when they are plugged in for a period of time
- The unit will not function while solely using the AC adapter
