Lenovo B50-45 Power Adapter
When choosing a new adapter, choosing the Lenovo brand one is always going to be the safest and easiest way to go. Because Lenovo has been known to use a single AC adapter that powers multiple other machines, be sure you choose the right one. A universal power adapter is another possibility if you are desperate. If you decide to buy an non-Lenovo adapter, it is imperative to note the output of amps and voltage. The Lenovo B50-45 power adapter has two main uses, charging the battery and to provide a source of power for the unit.
Major symptoms of a defective power adapter
- Most Lenovo AC adapters can get quite warm when plugged in for 10 minutes or more
- Battery does not charge completely
- The laptop does not work while just using AC power
