Lenovo S40-70 Power Adapter
When purchasing a replacement adapter, selecting the Lenovo OEM charger is always going to be the safest and easiest way to go. The Lenovo S40-70 power adapter provides two functions, to charge the onboard battery and powering the laptop. A universal power adapter can be used if yours is unavailable or backordered. If you decide to buy an non-Lenovo adapter, please check on both the voltage and amperage output. Due to the fact that one Lenovo adapter can be used on other units, be sure you choose the right one.
Major signs of a poorly working power adapter
- Battery does not charge at all
- Most Lenovo AC adapters will get very warm to the touch when they are plugged in for a period of time
- The unit will not work while solely using the AC adapter
