Sony VPCSA2EGX Power Adapter
Because Sony uses one power charger that can be used on other units, be certain to thoroughly note the part number that is needed for this model. The Sony VPCSA2EGX power adapter is responsible for two things, charging the battery and powering the laptop. If your decision is to purchase a different brand charger, make note of both the voltage and amperage output. A universal power adapter can be used if you are desperate. Upon choosing a replacement AC adapter, choosing the Sony brand one is usually going to be the safest choice.
Main clues your power adapter has very little life left
- Most Sony adapters can get quite warm when plugged in for any length of time
- The laptop does not operate using just the AC power adapter
- Battery does not charge up all the time
