rMBP polnilec in iskrenje | |||||
V Angliji sem kupil rMBP15 2015, ki je seveda prišel z angleškim plugom, tako da sem tisti adapter za v vtičnico kupil na ebayu. Pred časom sem tu bral, da ta adapter pa res nima nobene veze, če je fake ali original tako da sem kupil prvo stvar, kljub temu da je pisalo orginal (kar rahlo dvomim). Napetost imamo enako kot v Angliji, tako da to nebi smel biti problem. V glavnem ko plug vtaknem v vtičnico, se vse skupaj kar močno zaiskri. To se ne zgodi vedno, recimo ko to takoj ponovim se ne zgodi. Za zdaj se s tem nisem preveč ukvarjal, sem pač najprej vtaknil v vtičnico in šele potem priključil rMBP, čeprav itak nima veze glede na to da je vmes še cel apple brick. Kaj predlagate, da naredim v tem primeru? PS: Včasih, ko hočem priključiti kakšen USB, ob dotiku z računalnikom preskakujejo iskre. Tega že dalj časa nisem počel, ker imam načeloma vse Wireless, ampak včasih se to zgodi in nisem najbolj prepričan če je to normalno kljub tej šasiji. Možnosti priklopa s podaljškom seveda nimam, ker je tudi ta angleški. PS2: Macbook prenašam v sleevu in dodatno v torbi. Enkrat me je streslo(statika) že, ko sem se dotaknil poliestrske torbe. |

Nisem pa tega opazi pri Projih in iMacu. Je pa na iMacu občasno preskakovala statika iz prstov na žično tipkovnico. Zelo nadležno. Nekako je to problem tudi v ozemlitvi v hišni elektriki. Če se prav spomnim, smo enkrat ugotavljali, da se to ne dogaja čist povsod. Pa seveda šuko kabel tudi pomaga. Seveda, če je ozemljitev po bajti pravilno narejena. --- Je pa podobno tudi s tresenjem, če s prstom potegneš po aluminjastem robu MBPja. _________________ Get a life, get a Mac! ¯\_(ツ)_/¯ |

Zanimivo, potem smo vsi bolj ali manj na istem? Mislita, da potem ni fore v štek adapterju in da bi se iskrilo tudi z originalnim? |

Je pa Apple objavil program menjave: http://www.apple.com/si/support/ac-wallplug-adapter/ Kar bi znalo pomeniti, da tudi vsak kitajc ni za v vticnico... |

https://discussions.apple.com/thread/512900?start=0&tstart=0 Pa še razlaga: "The spark you see is completely normal. The reason has nothing to do with 'in rush' current or capacitors. It has to do with inductance. Any wire loop (any conductor has small inductance), such as a transformer, has an inductance. The transformer has a magnetic field (or lack of one) and when you plug-in or unplug the cord, current flows/stops and the magnetic field changes. Nature abhors a change in flux (change in the amount of mag field) and a counter current is induced by the inductor. This current causes the spark. There is no difference in how you connect the wires. The ring on the end which goes into your computer is the ground. It is designed to contact first, thus providing a path for transient currents to discharge before anything else. Plug it in slow, it shouldn't matter at all. Leaving a charger plugged into the wall without being connected to your computer is not likely to be harmful. You might consider not doing this if you think the power supply is getting old. The electronics inside are pretty robust and what really taxes them is when a large current is being drawn. There's a lot of power conditioning going on in there to clean up the power to be clean enough for a micro controller. In case you care, a switching power supply is one that avoids the need for large expensive transformers and uses a complicated circuit to lower the wall voltage down to 15VDC from about 60 VDC (120VAC / 2 from rectification). Image flapping a switch on and off, where 'on' is clamped to a value, like 15V. If you do this fast enough, the pulse train looks like a constant DC. Except there's a ton of noise and garbage from the switching. Computers' CPU don't use that much current, but all the peripherals sure do, DVD, montior, HDs, speakers, etc." _________________ Get a life, get a Mac! ¯\_(ツ)_/¯ |
