Sony PCG-GRT290Z 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-GRT290Z model. If your decision is to purchase a different brand charger, make note of both the voltage and amperage output. The Sony PCG-GRT290Z AC adapter has two main uses, to charge the onboard battery and powering the laptop. A universal AC adapter is a possibility if yours is unavailable or backordered. When choosing a new adapter, choosing the Sony brand one is usually going to be the safest choice.
Important signs the Sony power adapter will need to be replaced
- The majority of Sony power chargers get warm when plugged in for any length of time
- The laptop does not operate while just using AC power
- Battery does not charge completely
