Sony VPCY21EFX Power Adapter
When choosing a new AC adapter, the actual Sony brand is the best one to choose. Due to the fact that one Sony adapter is probably used on other similar units, make sure you check the part number for the correct one. The Sony VPCY21EFX AC adapter provides two functions, to charge up the main battery and powering the laptop. A universal AC adapter is another possibility but only if necessary. If your decision is to purchase a different brand charger, it is imperative to note the output of amps and voltage.
Indications of a defective laptop charger
- The laptop does not run without the battery installed
- Your Sony battery refuses to charge up all the time
- Most Sony AC adapters will get warm to the touch when plugged in for 10 minutes or more
