Sony PCG-GRT270K Power Adapter
When choosing a new charger, choosing the Sony brand one will probably be the safest way to go. If your decision is to purchase a different brand charger, please check on both the volts and amps outputs. Because Sony has been known to use a single AC adapter that can be used on other units, make sure you check the part number for the correct one. A universal AC adapter is another possibility if you absolutely need to. The Sony PCG-GRT270K AC adapter is needed for two reasons, to charge the onboard battery while simultaneously providing power for the laptop.
Red flags to watch for in a failing charger
- Most Sony adapters get warm when they are plugged in for a period of time
- The laptop does not work without the battery installed
- Your Sony battery refuses to charge whatsoever
