Sony VGN-SR390P Power Adapter
If your decision is to purchase a different brand charger, make note of the output of amps and voltage. Due to the fact that one Sony adapter is probably used on other similar units, make sure you check the part number for the correct one. A universal power adapter is a possibility but only if necessary. The Sony VGN-SR390P power adapter has two main uses, to charge any and all batteries and powering the laptop. When purchasing a replacement AC charger, choosing the Sony brand one will probably be the safest way to go.
Some warnings the power charger is dying
- The laptop does not run using just the AC power adapter
- Battery does not charge whatsoever
- Most Sony AC adapters can get quite warm when they are plugged in for a period of time
