Sony VGN-CR490 Power Adapter
If buying off-brand, please check on both the voltage and amperage output. Upon choosing a replacement AC charger, choosing the Sony brand one will probably be the safest way to go. A universal AC adapter is a possibility but only if necessary. 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. The Sony VGN-CR490 AC adapter has two main uses, to charge any and all batteries and powering the laptop.
What red flags are there that my laptop charger is in need of replacing?
- Most Sony AC adapters will get warm to the touch when plugged in for 10 minutes or more
- Battery does not charge up every time
- The unit will not work using just the AC power adapter
