Sony VPCEC4BFX Power Adapter
Upon choosing a replacement AC charger, selecting the Sony OEM charger will probably be the safest way to go. The Sony VPCEC4BFX AC adapter provides two functions, to charge up the main battery while simultaneously providing power for the laptop. If your decision is to purchase a different brand charger, make sure to check both the volts and amps outputs. A universal AC adapter can be used if you are desperate. Due to the fact that one Sony adapter is most likely used on other laptop models, be certain you select the correct one for the VPCEC4BFX model.
Subtle hints your AC adapter is dead
- Most Sony adapters get warm when plugged in for any length of time
- Battery does not charge completely
- The laptop does not operate while solely using the AC adapter
