Sony PCG-F690 Power Adapter
Because Sony uses one power charger that can be used on other units, be certain you select the correct one for the PCG-F690 model. When choosing a new AC charger, the actual Sony brand is usually going to be the safest choice. If buying off-brand, please check on both the voltage and amperage output. The Sony PCG-F690 power adapter has two main uses, to charge up the main battery while simultaneously providing power for the laptop. A universal power adapter is another possibility but only if necessary.
Signs the Sony power adapter is in dire straights
- The laptop does not work while solely using the AC adapter
- Most Sony AC adapters can get quite warm when plugged in for any length of time
- Battery does not charge whatsoever
