Sony PCG-719 Power Adapter
When purchasing a replacement adapter, choosing the Sony brand one is usually going to be the safest choice. Because Sony has been known to use a single AC adapter that is most likely used on other laptop models, be sure you choose the right one. The Sony PCG-719 AC adapter is responsible for two things, to charge up the main battery and powering the laptop. A universal power adapter is a possibility if you are desperate. If buying off-brand, make note of both the voltage and amperage output.
Major indications your laptop charger has very little life left
- Most Sony AC adapters will get very warm to the touch when plugged in for 10 minutes or more
- Battery does not charge up every time
- The unit will not run while just using AC power
