Sony PCG-F290 Power Adapter
When choosing a new adapter, the actual Sony brand is the best one to choose. If your decision is to purchase a different brand charger, please check on both the volts and amps outputs. A universal AC adapter is another possibility if you absolutely need to. The Sony PCG-F290 AC adapter provides two functions, to charge any and all batteries and to provide a source of power for the unit. Because Sony uses one power charger that is most likely used on other laptop models, double-check the part number or model number of the adapter.
General indicators that your the Sony power adapter will soon need to be replaced
- Your Sony battery refuses to charge all the time
- The laptop does not work while just using AC power
- Most Sony adapters get warm when they are plugged in for a period of time
