Sony VPCF12JFX Power Adapter
If buying off-brand, make note of the output of amps and voltage. Due to the fact that one Sony adapter powers multiple other machines, be certain to thoroughly note the part number that is needed for this model. A universal power adapter can be used if you absolutely need to. The Sony VPCF12JFX AC adapter is responsible for two things, to charge up the main battery while simultaneously providing power for the laptop. When purchasing a replacement AC charger, the actual Sony brand will probably be the safest way to go.
Clues of a declining AC adapter
- Battery does not charge up all the time
- The laptop does not function while solely using the AC adapter
- The majority of Sony power chargers will get very warm to the touch when plugged in for any length of time
