Sony PCG-K20P Power Adapter
Upon choosing a replacement AC adapter, choosing the Sony brand one is the best one to choose. The Sony PCG-K20P power adapter has two main uses, charging the battery and powering the laptop. A universal AC adapter can be used if yours is unavailable or backordered. Because Sony uses one power charger that powers multiple other machines, make sure you check the part number for the correct one. If your decision is to purchase a different brand charger, it is imperative to note both the volts and amps outputs.
Major signs your power adapter will not last the year
- Most Sony adapters get warm when plugged in for any length of time
- The unit will not function without the battery installed
- Battery does not charge up completely
