Sony VGN-BX540BW Power Adapter
If buying off-brand, make note of both the volts and amps outputs. The Sony VGN-BX540BW AC adapter is responsible for two things, to charge the onboard battery and to provide a source of power for the unit. When choosing a new AC charger, choosing the Sony brand one is always going to be the safest and easiest way to go. Due to the fact that one Sony adapter powers multiple other machines, double-check the part number or model number of the adapter. A universal power adapter can be used if you are desperate.
Some warnings the power charger is failing
- The laptop does not run using just the AC power adapter
- Battery does not charge at all
- Most Sony AC adapters can get quite warm when they are plugged in for a period of time

A Sony VGN-BX540BW power adapter should be purchased new for a variety of reasons, including wear and tear on any older used one. It is always best to make note of the OEM part number so you order the correct power adapter replacement. Be sure to always buy computer products from a known seller if you purchase through a website. The Sony VGN-BX540BW will thank you for buying smart.
