Sony PCG-K33P Power Adapter
When choosing a new AC adapter, the actual Sony brand is always going to be the safest and easiest way to go. If your decision is to purchase a different brand charger, make note of both the voltage and amperage output. A universal AC adapter is another possibility if you absolutely need to. The Sony PCG-K33P power adapter is needed for two reasons, to charge the onboard battery and to provide a source of power for the unit. Because Sony has been known to use a single AC adapter that can be used on other units, be sure you choose the right one.
Major signs your laptop charger is in dire straights
- The majority of Sony power chargers will get very warm to the touch when plugged in for 10 minutes or more
- Your Sony battery refuses to charge up every time
- The laptop does not work without the battery installed
