Lenovo G40-45 Power Adapter
The Lenovo G40-45 AC adapter is responsible for two things, to charge any and all batteries and powering the laptop. Because Lenovo has been known to use a single AC adapter that is most likely used on other laptop models, make sure you check the part number for the correct one. A universal AC adapter is another possibility if you absolutely need to. Upon choosing a replacement AC charger, choosing the Lenovo brand one is always going to be the safest and easiest way to go. If you decide to buy an non-Lenovo adapter, make sure to check the output of amps and voltage.
Major symptoms the Lenovo power adapter is in dire straights
- Battery does not charge up completely
- Most Lenovo AC adapters will get warm to the touch when plugged in for any length of time
- The laptop does not function while just using AC power
