Lenovo G40-80 Power Adapter
When purchasing a replacement adapter, selecting the Lenovo OEM charger will probably be the safest way to go. If you decide to buy an non-Lenovo adapter, it is imperative to note both the volts and amps outputs. Because Lenovo uses one power charger that is probably used on other similar units, be certain you select the correct one for the G40-80 model. The Lenovo G40-80 AC adapter has two main uses, to charge any and all batteries and powering the laptop. A universal AC adapter is a possibility but only if necessary.
What are some indications that my AC adapter needs replacing?
- Your Lenovo battery refuses to charge up completely
- Most Lenovo adapters will get very warm to the touch when they are plugged in for a period of time
- The laptop does not operate while just using AC power
