Sony VGN-Z790 Power Adapter
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. Upon choosing a replacement adapter, the actual Sony brand will probably be the safest way to go. The Sony VGN-Z790 power adapter provides two functions, charging the battery while simultaneously providing power for the laptop. If your decision is to purchase a different brand charger, please check on both the volts and amps outputs. A universal AC adapter can be used if you absolutely need to.
Some clues your laptop charger has very little life left
- The unit will not run while solely using the AC adapter
- Battery does not charge up at all
- Most Sony adapters will get warm to the touch when plugged in for 10 minutes or more
