Sony VGN-SZ491N Power Adapter
Because Sony uses one power charger that can be used on other units, make sure you check the part number for the correct one. If buying off-brand, make note of the output of amps and voltage. A universal AC adapter can be used but only if necessary. When purchasing a replacement AC adapter, the actual Sony brand is usually going to be the safest choice. The Sony VGN-SZ491N power adapter is needed for two reasons, charging the battery while simultaneously providing power for the laptop.
Hints your laptop charger will need replacing
- The majority of Sony power chargers will get very warm to the touch when plugged in for any length of time
- Battery does not charge up every time
- The laptop does not function using just the AC power adapter
