Sony VGN-Z790D Power Adapter
The Sony VGN-Z790D AC adapter is responsible for two things, charging the battery while simultaneously providing power for the laptop. Upon choosing a replacement AC charger, choosing the Sony brand one is always going to be the safest and easiest way to go. If your decision is to purchase a different brand charger, make note of the output of amps and voltage. A universal power adapter is another possibility but only if necessary. Because Sony uses one power charger that is probably used on other similar units, be certain you select the correct one for the VGN-Z790D model.
General warnings poorly running AC adapter
- Most Sony adapters will get very warm to the touch when they are plugged in for a period of time
- Battery does not charge up at all
- The laptop does not function using just the AC power adapter
