Sony PCG-K12P Power Adapter
Because Sony uses one power charger that is probably used on other similar units, be certain to thoroughly note the part number that is needed for this model. The Sony PCG-K12P AC adapter is needed for two reasons, to charge any and all batteries and powering the laptop. When choosing a new AC charger, the actual Sony brand is always going to be the safest and easiest way to go. If buying off-brand, please check on both the volts and amps outputs. A universal power adapter can be used if you absolutely need to.
Major warnings to watch for in a bad AC adapter
- Your Sony battery refuses to charge up whatsoever
- Most Sony adapters will get warm to the touch when plugged in for any length of time
- The laptop does not function using just the AC power adapter
