Sony VGN-TX770P Power Adapter
When purchasing a replacement charger, selecting the Sony OEM charger is usually going to be the safest choice. The Sony VGN-TX770P AC adapter is responsible for two things, charging the battery and to provide a source of power for the unit. If buying off-brand, it is imperative to note the output of amps and voltage. A universal AC adapter is another possibility if you absolutely need to. Due to the fact that one Sony adapter is most likely used on other laptop models, be certain to thoroughly note the part number that is needed for this model.
General indicators that your laptop charger has very little life left
- The majority of Sony power chargers get warm when they are plugged in for a period of time
- Battery does not charge completely
- The unit will not work while solely using the AC adapter
