Lenovo B40-80 Power Adapter
The Lenovo B40-80 AC adapter provides two functions, 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. Due to the fact that one Lenovo adapter powers multiple other machines, make sure you check the part number for the correct one. When purchasing a replacement adapter, choosing the Lenovo brand one is always going to be the safest and easiest way to go. A universal power adapter can be used if yours is unavailable or backordered.
