Sony VGN-CS190N Power Adapter
If you decide to buy an non-Sony adapter, please check on the output of amps and voltage. The Sony VGN-CS190N power adapter provides two functions, to charge any and all batteries while simultaneously providing power for the laptop. A universal AC adapter can be used but only if necessary. When purchasing a replacement adapter, the actual Sony brand will probably be the safest way to go. Due to the fact that one Sony adapter powers multiple other machines, be certain you select the correct one for the VGN-CS190N model.
Red flags of a poorly working Sony power adapter
- Most Sony AC adapters can get quite warm when plugged in for any length of time
- Battery does not charge completely
- The unit will not function using just the AC power adapter
