Lenovo ThinkPad W540 Power Adapter
If you decide to buy an non-Lenovo adapter, please check on the output of amps and voltage. The Lenovo ThinkPad W540 power adapter provides two functions, to charge up the main battery and to provide a source of power for the unit. 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. When choosing a new charger, selecting the Lenovo OEM charger is usually going to be the safest choice. A universal AC adapter can be used if you are desperate.
Symptoms the power charger has very little life left
- Your Lenovo battery refuses to charge whatsoever
- The laptop does not run while just using AC power
- Most Lenovo adapters will get warm to the touch when plugged in for 10 minutes or more
