Sony PCG-NV190 Power Adapter
The Sony PCG-NV190 power adapter provides two functions, charging the battery and powering the laptop. If buying off-brand, it is imperative to note both the volts and amps outputs. Because Sony uses one power charger that powers multiple other machines, be certain you select the correct one for the PCG-NV190 model. When choosing a new adapter, selecting the Sony OEM charger is always going to be the safest and easiest way to go. A universal AC adapter is another possibility if you are desperate.
Some warnings your AC adapter is going to die
- Most Sony AC adapters will get warm to the touch when they are plugged in for a period of time
- The unit will not function using just the AC power adapter
- Your Sony battery refuses to charge completely
