Sony PCG-GR290K Power Adapter
Because Sony has been known to use a single AC adapter that powers multiple other machines, be certain you select the correct one for the PCG-GR290K model. If you decide to buy an non-Sony adapter, make sure to check both the voltage and amperage output. A universal AC adapter can be used if you are desperate. When purchasing a replacement AC charger, selecting the Sony OEM charger is always going to be the safest and easiest way to go. The Sony PCG-GR290K power adapter is responsible for two things, to charge any and all batteries and to provide a source of power for the unit.
Simple indications of an ineffective Sony power adapter
- The unit will not work while solely using the AC adapter
- Your Sony battery refuses to charge up completely
- Most Sony adapters will get very warm to the touch when plugged in for 10 minutes or more
