Lenovo ThinkPad E550 Power Adapter
When purchasing a replacement adapter, selecting the Lenovo OEM charger will probably be the safest way to go. If buying off-brand, make note of both the voltage and amperage output. The Lenovo ThinkPad E550 AC adapter has two main uses, charging the battery and powering the laptop. A universal power adapter is another possibility if you are desperate. 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.
What red flags are there that my charger has gone bad?
- Your Lenovo battery refuses to charge whatsoever
- The laptop does not run without the battery installed
- Most Lenovo adapters will get warm to the touch when they are plugged in for a period of time
