Sony VGN-CR4000 Power Adapter
Because Sony has been known to use a single AC adapter that is probably used on other similar units, make sure you check the part number for the correct one. The Sony VGN-CR4000 power adapter has two main uses, to charge any and all batteries and to provide a source of power for the unit. When choosing a new AC charger, selecting the Sony OEM charger is usually going to be the safest choice. If you decide to buy an non-Sony adapter, it is imperative to note both the volts and amps outputs. A universal power adapter is another possibility if you are desperate.
What red flags are there that my charger is almost dead?
- Battery does not charge up at all
- The unit will not operate using just the AC power adapter
- The majority of Sony power chargers get warm when plugged in for 10 minutes or more
