Sony VGN-CR540E Power Adapter
Because Sony has been known to use a single AC adapter that can be used on other units, be certain you select the correct one for the VGN-CR540E model. When purchasing a replacement AC charger, choosing the Sony brand one is always going to be the safest and easiest way to go. If buying off-brand, make sure to check both the voltage and amperage output. The Sony VGN-CR540E AC adapter is needed for two reasons, to charge the onboard battery and powering the laptop. A universal power adapter is a possibility if you are desperate.
Major indications the power charger needs replacing
- Battery does not charge completely
- Most Sony AC adapters will get warm to the touch when they are plugged in for a period of time
- The unit will not run while solely using the AC adapter
