Sony VGN-FE790 Power Adapter
Upon choosing a replacement adapter, the actual Sony brand is always going to be the safest and easiest way to go. Because Sony uses one power charger that can be used on other units, double-check the part number or model number of the adapter. The Sony VGN-FE790 AC adapter is responsible for two things, charging the battery and powering the laptop. A universal AC adapter is another possibility if you are desperate. If your decision is to purchase a different brand charger, it is imperative to note the output of amps and voltage.
Important signs the Sony power adapter needs a replacement ASAP
- Most Sony adapters can get quite warm when plugged in for 10 minutes or more
- Your Sony battery refuses to charge up every time
- The laptop does not work while solely using the AC adapter
