Sony PCG-NV309 Power Adapter
The Sony PCG-NV309 AC adapter is responsible for two things, to charge any and all batteries while simultaneously providing power for the laptop. If your decision is to purchase a different brand charger, please check on both the voltage and amperage output. Because Sony uses one power charger that is probably used on other similar units, make sure you check the part number for the correct one. A universal AC adapter is a possibility but only if necessary. Upon choosing a replacement adapter, choosing the Sony brand one is always going to be the safest and easiest way to go.
What happens when my power adapter is almost dead?
- Your Sony battery refuses to charge whatsoever
- The majority of Sony power chargers will get warm to the touch when plugged in for 10 minutes or more
- The unit will not function using just the AC power adapter
