Sony VGN-FW370J Power Adapter
The Sony VGN-FW370J AC adapter provides two functions, to charge the onboard battery while simultaneously providing power for the laptop. If buying off-brand, make sure to check both the voltage and amperage output. Because Sony uses one power charger that is most likely used on other laptop models, make sure you check the part number for the correct one. Upon choosing a replacement AC charger, selecting the Sony OEM charger is usually going to be the safest choice. A universal AC adapter can be used if you absolutely need to.
Red flags your laptop charger should need replacing
- Most Sony AC adapters will get very warm to the touch when plugged in for 10 minutes or more
- Your Sony battery refuses to charge up whatsoever
- The laptop does not run while just using AC power
