Lenovo B480 Power Adapter
If you decide to buy an non-Lenovo adapter, make note of both the volts and amps outputs. The Lenovo B480 power adapter is responsible for two things, to charge the onboard battery while simultaneously providing power for the laptop. Due to the fact that one Lenovo adapter is probably used on other similar units, double-check the part number or model number of the adapter. Upon choosing a replacement adapter, the actual Lenovo brand is usually going to be the safest choice. A universal power adapter can be used if you absolutely need to.
Signs the power charger is going to die
- Most Lenovo adapters get warm when they are plugged in for a period of time
- The unit will not work while just using AC power
- Battery does not charge up at all
