Sony PCG-GRT290ZP Power Adapter
Due to the fact that one Sony adapter can be used on other units, be certain you select the correct one for the PCG-GRT290ZP model. When choosing a new AC charger, choosing the Sony brand one is the best one to choose. The Sony PCG-GRT290ZP power adapter is responsible for two things, charging the battery and to provide a source of power for the unit. A universal AC adapter can be used but only if necessary. If you decide to buy an non-Sony adapter, make note of both the volts and amps outputs.
Key clues of a weakening laptop charger
- The laptop does not run using just the AC power adapter
- Most Sony adapters will get warm to the touch when plugged in for any length of time
- Battery does not charge up completely
