Lenovo ThinkPad T440S Power Adapter
Due to the fact that one Lenovo adapter can be used on other units, be certain to thoroughly note the part number that is needed for this model. If you decide to buy an non-Lenovo adapter, make sure to check both the voltage and amperage output. A universal power adapter is a possibility if you absolutely need to. The Lenovo ThinkPad T440S AC adapter is responsible for two things, to charge up the main battery and powering the laptop. Upon choosing a replacement AC adapter, selecting the Lenovo OEM charger will probably be the safest way to go.
General indicators that your the power charger will need replacing
- The majority of Lenovo power chargers get warm when they are plugged in for a period of time
- Battery does not charge up all the time
- The unit will not operate while solely using the AC adapter
