Sony PCG-K33 Power Adapter
The Sony PCG-K33 AC adapter has two main uses, charging the battery and powering the laptop. When choosing a new AC adapter, selecting the Sony OEM charger is usually going to be the safest choice. Because Sony uses one power charger that is probably used on other similar units, be sure you choose the right one. A universal AC adapter is a possibility if you are desperate. If buying off-brand, make note of both the volts and amps outputs.
Indications your laptop charger is in need of replacing
- The unit will not function without the battery installed
- Most Sony AC adapters get warm when plugged in for any length of time
- Battery does not charge every time
