Sony VGN-SR499DEB Power Adapter
Upon choosing a replacement adapter, choosing the Sony brand one is always going to be the safest and easiest way to go. The Sony VGN-SR499DEB AC adapter is needed for two reasons, to charge the onboard battery and powering the laptop. A universal AC adapter is another possibility but only if necessary. If buying off-brand, please check on the output of amps and voltage. Due to the fact that one Sony adapter is most likely used on other laptop models, be sure you choose the right one.
What to see if the charger is about to stop working?
- Battery does not charge at all
- Most Sony AC adapters will get very warm to the touch when plugged in for 10 minutes or more
- The laptop does not operate without the battery installed
