Lenovo IdeaPad Z40-75 Power Adapter
Upon choosing a replacement charger, choosing the Lenovo brand one is always going to be the safest and easiest way to go. Because Lenovo uses one power charger that powers multiple other machines, be certain to thoroughly note the part number that is needed for this model. The Lenovo IdeaPad Z40-75 AC adapter is responsible for two things, charging the battery and powering the laptop. If buying off-brand, it is imperative to note the output of amps and voltage. A universal power adapter is a possibility if you absolutely need to.
What happens when my AC adapter has to be replaced?
- Most Lenovo adapters will get very warm to the touch when they are plugged in for a period of time
- Your Lenovo battery refuses to charge completely
- The laptop does not operate while solely using the AC adapter
