Sony PCG-505TR Power Adapter
Upon choosing a replacement charger, the actual Sony brand will probably be the safest way to go. The Sony PCG-505TR AC adapter is needed for two reasons, to charge any and all batteries and powering the laptop. If buying off-brand, make note of both the voltage and amperage output. A universal power adapter can be used if you are desperate. Because Sony has been known to use a single AC adapter that is probably used on other similar units, be certain you select the correct one for the PCG-505TR model.
Key indicators that my charger is about to go out?
- Most Sony adapters will get warm to the touch when they are plugged in for a period of time
- The laptop does not run while just using AC power
- Battery does not charge up all the time
