Sony VGN-AW290 Power Adapter
If your decision is to purchase a different brand charger, make note of the output of amps and voltage. The Sony VGN-AW290 power adapter is responsible for two things, to charge the onboard battery and to provide a source of power for the unit. A universal power adapter can be used but only if necessary. When purchasing a replacement adapter, choosing the Sony brand one is usually going to be the safest choice. Because Sony uses one power charger that powers multiple other machines, double-check the part number or model number of the adapter.
Important clues of a declining power adapter
- Most Sony adapters can get quite warm when plugged in for 10 minutes or more
- Your Sony battery refuses to charge up whatsoever
- The laptop does not run without the battery installed
