Lenovo S20-30 Power Adapter
The Lenovo S20-30 AC adapter has two main uses, to charge up the main battery while simultaneously providing power for the laptop. If buying off-brand, make sure to check both the volts and amps outputs. Upon choosing a replacement charger, selecting the Lenovo OEM charger will probably be the safest way to go. A universal power adapter can be used if you are desperate. Because Lenovo uses one power charger that is most likely used on other laptop models, make sure you check the part number for the correct one.
Chief elements of an ailing Lenovo power adapter
- Your Lenovo battery refuses to charge every time
- The unit will not work without the battery installed
- Most Lenovo AC adapters can get quite warm when plugged in for any length of time
