My cat obliterated my power cord yesterday. Being a student, spending around 100 euros on a new charger was not an option. So I found a 10-years-experience-in repairing-electronics-company and they replaced my power cord today for around 25 euros.
The process was opening the 'main-box aka the charger itself', cutting the power cord and replacing it with a new one from what they told me (wasn't done in front of me). The charger looks like brand new (by brand new I mean, looks like before the operation, they didn't cracked the case or used duct tape to close it after the process was over) so apparently they didn't lied around the part that they are pro. They also told me that the replacement cord is genuine.
Now, how can I actually check if it is genuine as I am concerned to not get my Macbook fried. Or should I ask what are the risks of having a fake power cord ? Tho' I suppose having a power cord fake should be less dangerous than the entire charger.
I am asking these questions as the MagSafe2 adapter looks quite shady, as the light from the charging LED is leaking around the cord. I attached a picture to be more specific.
After they replaced the cord and tested the charger so I could see that the laptop is charging they went through the menu and showed me some info regarding the power (60W) and infos I simply did not understood. I will post a picture of that screen with those informations. As I do not know how they were before replacing the charger, I cannot compare to the current values.
