Lenovo B575 Power Adapter
Because Lenovo has been known to use a single AC adapter that is most likely used on other laptop models, make sure you check the part number for the correct one. The Lenovo B575 AC adapter has two main uses, to charge the onboard battery and to provide a source of power for the unit. If your decision is to purchase a different brand charger, it is imperative to note both the volts and amps outputs. When purchasing a replacement AC charger, selecting the Lenovo OEM charger is the best one to choose. A universal AC adapter is another possibility but only if necessary.
Key clues to watch for in a bad charger
- Battery does not charge up whatsoever
- The majority of Lenovo power chargers get warm when they are plugged in for a period of time
- The unit will not function using just the AC power adapter
