Lenovo ThinkPad Edge E440 Power Adapter
The Lenovo ThinkPad Edge E440 AC adapter has two main uses, to charge the onboard battery while simultaneously providing power for the laptop. If buying off-brand, make note of the output of amps and voltage. When purchasing a replacement adapter, choosing the Lenovo brand one will probably be the safest way to go. Because Lenovo uses one power charger that can be used on other units, be certain to thoroughly note the part number that is needed for this model. A universal power adapter is another possibility if you absolutely need to.
What are the signs that the Lenovo AC adapter has gone bad?
- The majority of Lenovo power chargers can get quite warm when they are plugged in for a period of time
- The unit will not run while solely using the AC adapter
- Your Lenovo battery refuses to charge every time
