Lenovo ThinkPad S540 Power Adapter
Upon choosing a replacement AC adapter, selecting the Lenovo OEM charger is the best one to choose. Because Lenovo has been known to use a single AC adapter that can be used on other units, be sure you choose the right one. The Lenovo ThinkPad S540 power adapter has two main uses, to charge up the main battery and powering the laptop. If you decide to buy an non-Lenovo adapter, it is imperative to note both the voltage and amperage output. A universal power adapter is another possibility if yours is unavailable or backordered.
Indications to watch for in a failing AC adapter
- The laptop does not function using just the AC power adapter
- Battery does not charge at all
- Most Lenovo AC adapters will get warm to the touch when plugged in for 10 minutes or more
