Model Specific: Swift 3 SF314-57-736C
Issue: Laptop is not charging and doesn't display the power-in light and doesn't 'beep' when power from transformer is inserted. 

I did test the voltage and measures correct.
I have bought another power supply just to make sure and it doesn't indicate power-in either.
Measured voltage correct on both

Suspect it may be the connector or some fuse on the small DC-I/O PCB inside the laptop. 

Doesn't seem you can buy these anywhere. 

Question is if anyone knows if you can get this DC-I/O PCB or can get someone to replace the fuse.

    Likely got zapped then, that's usually the cause of a failed MOSFET...

    Hi mogwaai,

    Did you try with different charger.

    Yes, I bought a second one and tested voltages

    It's some component inside the laptop either connector or a fuse hopefully. I'll just buy the DC I/O PCB if neccessary - bit difficult to find. If anyone knows?

    Now am back on my old HP and I'm not enjoying it one bit.

    The power jack is soldered to the motherboard. I believe the card you refer to is the USB card that has the audio jack and speaker connectors on the other side of the laptop.

    Yes,

    Has USB and power connector. Hoping it may be component on this board rather than the MB. 

    Laptop does switch on with what power it has left though. Possible connector power issue

    It looks like hardware issue. Contact acer tech support,

    That board doesn't have a power connector. It has the speaker/mic jack (black plastic) and a USB port (silver), the connections for the speakers and the connector for the ribbon to the motherboard. The power jack is on the other side of the computer where it's soldered to the MB. If you are trying to plug your power connector into that audio jack it will not work. :)

    LOL, was hoping it was where the power light was... ;) Will take it in I guess have no choice. Only 1 1/2 year old. First Acer I bought and was enjoying using it.
