Sony PCG-GR390K Power Adapter
The Sony PCG-GR390K power adapter is responsible for two things, to charge any and all batteries and powering the laptop. Because Sony has been known to use a single AC adapter that is probably used on other similar units, double-check the part number or model number of the adapter. If buying off-brand, please check on both the voltage and amperage output. A universal AC adapter is another possibility but only if necessary. When choosing a new charger, selecting the Sony OEM charger will probably be the safest way to go.
Important hints your laptop charger has to be replaced
- Battery does not charge up all the time
- The unit will not operate while just using AC power
- Most Sony adapters will get warm to the touch when plugged in for 10 minutes or more
