Acer Swift 3 SF314-41-R8HZ power plug

Dentoxx

I have an Acer Swift 3 SF314-41-R8HZ and I have the problem that the power plug is only super loose in the power socket and either slips out with smaller movements of the notebook or can no longer make contact. I wonder if this is a general problem in this series, since I already have the second new device and the problem has always existed from the beginning. I also have the same problem with the headphone output on both devices, namely that when the headphones are plugged in, there is always a loud crackle when no music is playing or music is being started again. Anyone else with this kind of problem?

The loose connection on the power plug is a bit inherent in the small plugs like this. There is a spring contact inside the jack that pushes sideways on the barrel of the plug, forcing the center electrode to contact the center hole in the barrel. There's not a lot of room inside the socket, so there's not a lot of side force from the spring. With the older (and thicker) laptops there was enough room inside to use a larger socket and plug which was a lot more tolerant. All you can really do is make sure it's fully seated, there should be a slight click feel when it in all the way.

The phono jack has the same issue, though sometimes it's an actual incompatibility. When it's not fully seated you can get the contacts inside the jack to just touch the join between the contacts on the plug, which causes a bit of cross talk leading to noise when they aren't being driven. You can also see somewhat the same issue if the jack and plug don't match. Some headphones have the mic and ground reversed, which also leads to noise.
