Sony PCG-GRS170 Power Adapter
If buying off-brand, make note of the output of amps and voltage. When choosing a new AC charger, the actual Sony brand is the best one to choose. The Sony PCG-GRS170 power adapter has two main uses, charging the battery and powering the laptop. A universal AC adapter is another possibility if you are desperate. Because Sony has been known to use a single AC adapter that is probably used on other similar units, make sure you check the part number for the correct one.
Key symptoms of a weakening Sony power adapter
- Your Sony battery refuses to charge up every time
- The laptop does not run while just using AC power
- Most Sony adapters will get warm to the touch when they are plugged in for a period of time
