Lenovo G550 Power Adapter
When purchasing a replacement adapter, choosing the Lenovo brand one is the best one to choose. If your decision is to purchase a different brand charger, please check on the output of amps and voltage. Because Lenovo has been known to use a single AC adapter that is most likely used on other laptop models, be certain you select the correct one for the G550 model. A universal power adapter is another possibility if you are desperate. The Lenovo G550 power adapter is responsible for two things, to charge the onboard battery while simultaneously providing power for the laptop.
Cues of an ineffective AC adapter
- Most Lenovo adapters can get quite warm when plugged in for 10 minutes or more
- The laptop does not function without the battery installed
- Battery does not charge up completely
