Sony PCG-TR2A Power Adapter
If you decide to buy an non-Sony adapter, make note of both the voltage and amperage output. When purchasing a replacement charger, choosing the Sony brand one will probably be the safest way to go. A universal AC adapter is another possibility if yours is unavailable or backordered. Because Sony has been known to use a single AC adapter that is probably used on other similar units, make sure you check the part number for the correct one. The Sony PCG-TR2A power adapter provides two functions, charging the battery while simultaneously providing power for the laptop.
Key clues of a declining laptop charger
- Battery does not charge all the time
- The majority of Sony power chargers get warm when plugged in for any length of time
- The laptop does not operate using just the AC power adapter
