Sony VPCEA3SFX Power Adapter
The Sony VPCEA3SFX power adapter is needed for two reasons, charging the battery and powering the laptop. Upon choosing a replacement charger, choosing the Sony brand one is usually going to be the safest choice. A universal AC adapter can be used but only if necessary. Due to the fact that one Sony adapter powers multiple other machines, be certain you select the correct one for the VPCEA3SFX model. If buying off-brand, it is imperative to note the output of amps and voltage.
How do you know when your AC adapter is almost dead?
- The majority of Sony power chargers can get quite warm when plugged in for any length of time
- The laptop does not work using just the AC power adapter
- Battery does not charge all the time
