Sony PCG-GRT170 Power Adapter
When choosing a new charger, selecting the Sony OEM charger is the best one to choose. The Sony PCG-GRT170 AC adapter is needed for two reasons, to charge any and all batteries and powering the laptop. If your decision is to purchase a different brand charger, please check on both the voltage and amperage output. 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-GRT170 model. A universal power adapter is another possibility if you absolutely need to.
Some warnings of an inadequate power adapter
- The laptop does not function while solely using the AC adapter
- Most Sony adapters get warm when plugged in for 10 minutes or more
- Battery does not charge completely
