Sony VGN-SR399P Power Adapter
Due to the fact that one Sony adapter powers multiple other machines, double-check the part number or model number of the adapter. If your decision is to purchase a different brand charger, make note of both the voltage and amperage output. The Sony VGN-SR399P power adapter provides two functions, charging the battery and to provide a source of power for the unit. A universal AC adapter can be used but only if necessary. Upon choosing a replacement charger, selecting the Sony OEM charger is usually going to be the safest choice.
How do you know if your laptop charger really needs to be replaced?
- Most Sony AC adapters can get quite warm when plugged in for any length of time
- The unit will not function using just the AC power adapter
- Battery does not charge up all the time
