Sony PCG-GR300 Power Adapter
Upon choosing a replacement charger, choosing the Sony brand one is usually going to be the safest choice. If buying off-brand, please check on both the voltage and amperage output. Because Sony has been known to use a single AC adapter that powers multiple other machines, double-check the part number or model number of the adapter. The Sony PCG-GR300 AC adapter is responsible for two things, to charge up the main battery while simultaneously providing power for the laptop. A universal AC adapter is another possibility if you absolutely need to.
Major indications of an inadequate charger
- The unit will not work while solely using the AC adapter
- The majority of Sony power chargers will get very warm to the touch when plugged in for 10 minutes or more
- Your Sony battery refuses to charge whatsoever
