Sony VGN-TZ340 Power Adapter
The Sony VGN-TZ340 AC adapter has two main uses, to charge up the main battery and powering the laptop. Because Sony uses one power charger that is most likely used on other laptop models, be certain to thoroughly note the part number that is needed for this model. When purchasing a replacement AC adapter, selecting the Sony OEM charger is the best one to choose. A universal AC adapter is another possibility if you are desperate. If you decide to buy an non-Sony adapter, please check on the output of amps and voltage.
Signals the power charger will need replacing
- Battery does not charge up whatsoever
- The majority of Sony power chargers will get very warm to the touch when plugged in for any length of time
- The unit will not work while just using AC power
