Sony VGN-FW373J Power Adapter
Upon choosing a replacement AC charger, selecting the Sony OEM charger is the best one to choose. If your decision is to purchase a different brand charger, make sure to check both the voltage and amperage output. Due to the fact that one Sony adapter powers multiple other machines, double-check the part number or model number of the adapter. The Sony VGN-FW373J AC adapter is needed for two reasons, to charge any and all batteries and powering the laptop. A universal AC adapter can be used but only if necessary.
What are some hints that my laptop charger is not working properly?
- Most Sony AC adapters will get very warm to the touch when they are plugged in for a period of time
- Your Sony battery refuses to charge up whatsoever
- The unit will not run using just the AC power adapter
