Sony VGN-NR290E Power Adapter
Because Sony has been known to use a single AC adapter that 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 sure to check the output of amps and voltage. The Sony VGN-NR290E 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, selecting the Sony OEM charger is the best one to choose.
Red flags of an inadequate Sony power adapter
- Most Sony AC adapters get warm when plugged in for any length of time
- The laptop does not function without the battery installed
- Battery does not charge all the time
