Lenovo B50-70 Power Adapter
Due to the fact that one Lenovo adapter powers multiple other machines, make sure you check the part number for the correct one. The Lenovo B50-70 power adapter is responsible for two things, charging the battery and to provide a source of power for the unit. When purchasing a replacement adapter, the actual Lenovo brand will probably be the safest way to go. A universal AC adapter is a possibility if yours is unavailable or backordered. If you decide to buy an non-Lenovo adapter, make note of both the volts and amps outputs.
Important clues of a weak AC adapter
- The unit will not operate while solely using the AC adapter
- Battery does not charge up all the time
- The majority of Lenovo power chargers will get warm to the touch when plugged in for any length of time
