Sony PCG-SR27 Power Adapter
When choosing a new AC adapter, the actual Sony brand will probably be the safest way to go. The Sony PCG-SR27 power adapter provides two functions, charging the battery and powering the laptop. A universal AC adapter is a possibility if you are desperate. If buying off-brand, it is imperative to note both the volts and amps outputs. Because Sony uses one power charger that can be used on other units, double-check the part number or model number of the adapter.
What signals that my AC adapter has gone bad?
- Most Sony adapters will get warm to the touch when plugged in for 10 minutes or more
- Your Sony battery refuses to charge whatsoever
- The laptop does not operate while just using AC power
