Lenovo ThinkPad Edge E40 Power Adapter
Because Lenovo uses one power charger that is probably used on other similar units, make sure you check the part number for the correct one. The Lenovo ThinkPad Edge E40 power adapter is responsible for two things, charging the battery and powering the laptop. When choosing a new AC adapter, choosing the Lenovo brand one will probably be the safest way to go. A universal AC adapter is another possibility if you absolutely need to. If buying off-brand, please check on both the voltage and amperage output.
How do you know when your charger really needs to be replaced?
- The unit will not run without the battery installed
- Your Lenovo battery refuses to charge all the time
- Most Lenovo AC adapters will get very warm to the touch when they are plugged in for a period of time
