Sony PCG-FX310 Power Adapter
When purchasing a replacement adapter, choosing the Sony brand one is always going to be the safest and easiest way to go. If buying off-brand, make sure to check both the voltage and amperage output. The Sony PCG-FX310 AC adapter provides two functions, charging the battery while simultaneously providing power for the laptop. Due to the fact that one Sony adapter is most likely used on other laptop models, make sure you check the part number for the correct one. A universal power adapter is a possibility but only if necessary.
Signs of an inadequate laptop charger
- The majority of Sony power chargers will get warm to the touch when plugged in for any length of time
- The unit will not function without the battery installed
- Battery does not charge at all
