Sony VGN-B100B Power Adapter
The Sony VGN-B100B power adapter is responsible for two things, to charge up the main battery while simultaneously providing power for the laptop. When purchasing a replacement adapter, selecting the Sony OEM charger is always going to be the safest and easiest way to go. Because Sony has been known to use a single AC adapter that powers multiple other machines, be certain you select the correct one for the VGN-B100B model. If you decide to buy an non-Sony adapter, make sure to check both the volts and amps outputs. A universal power adapter can be used but only if necessary.
Key signs of an inadequate Sony power adapter
- The unit will not function using just the AC power adapter
- The majority of Sony power chargers will get warm to the touch when they are plugged in for a period of time
- Your Sony battery refuses to charge up completely
