Lenovo M490S Power Adapter
When choosing a new AC adapter, choosing the Lenovo brand one is always going to be the safest and easiest way to go. If your decision is to purchase a different brand charger, make sure to check the output of amps and voltage. The Lenovo M490S AC adapter provides two functions, to charge the onboard battery and powering the laptop. Because Lenovo uses one power charger that is probably used on other similar units, be sure you choose the right one. A universal power adapter is another possibility if you absolutely need to.
Warnings your power adapter will soon need to be replaced
- The majority of Lenovo power chargers get warm when plugged in for any length of time
- Battery does not charge completely
- The laptop does not operate without the battery installed
