Lenovo B4400 Power Adapter
The Lenovo B4400 power adapter is needed for two reasons, to charge the onboard battery while simultaneously providing power for the laptop. Upon choosing a replacement charger, selecting the Lenovo OEM charger will probably be the safest way to go. A universal AC adapter is a possibility if you absolutely need to. If buying off-brand, it is imperative to note both the volts and amps outputs. Because Lenovo uses one power charger that is probably used on other similar units, double-check the part number or model number of the adapter.
Clues your power adapter needs replacing ASAP
- The majority of Lenovo power chargers will get warm to the touch when plugged in for 10 minutes or more
- Battery does not charge up at all
- The unit will not work while solely using the AC adapter

Always purchase electronic parts from a site you know when you buy your parts online. It is always best to check and double-check the manufacturers part number before buying a power adapter replacement.
