    If only there were more computer repairman who actually care about the quality of their work the way you do I feel people would feel much more inclined to go to shops instead of going out and just buying a new. Preventing a lot more e-waste from ending up in a landfill. Excellent job well done!

    I have exactly the same problem. The computer was working when I shut it down, but did not use or power up for over a year, so figured the battery was stone dead and not activating the charging system. A new battery, unfortunately did not fix the issue. I need to learn how to remove and solder chips to a MB first before I try this repair. Learned a lot about how techs work with chips. As soon as I have the proper materials and tools, I try to resolder the chip. If I can find a power board, I'll try that first, maybe even unclip and clean the contacts first. Thanks for such a great video. :-)

    first of all would like to say big THANK YOU! for this amazing tutorial i was able to fix my macbook air as same with the title of this video no power and no light on charger. what i did is check that specific chip and using my smart phone to zoom it so that i can see what's the problem and it corroded so i clean it up by using tooth brush and alcohol and it works! i don't have the tools that you used in this video but i copy the last part of this video by cleaning smc chip or i don't know what is called anyway thank you again boss!

    I bought a MBA last night for about $120. Early 2015 complete with box and original accessories. It had stopped working, worked intermittently and when Apple took a look, they were unable to determine what was wrong. They suggested that the owner upgrade to a new MBA and they would recycle the broken one.
    So it was advertised as ‘parts only’.
    Charger light came on, but it would not start.
    I left it to charge to 10% and reset the SMC.
    It started up.
    Not only that, it’s currently running Big Sur…
    One owner before me, it’s in great condition and I think I’ll keep it as a daily driver for a little while.

    Hi, I had problem with my Macbook pro A1502 which I believe the battery drained during sleep mode, its happened like twice before but it managed to turn on normally after battery charge or while on charge. It happened again yesterday and this time the charge indicator keeps red even charge for longer time and it wont turn on. I did try to reset SMC while charging, it did shown indicator turn green for few seconds after releasing the keys but it not running. I also did try to check the battery by removing the back cover and its not shown any fault in condition such as bulging. Please do help me before Im trying to change the battery since I cant think of something else. Theyre no warning about battery (before it happened) but I do believe the battery may also has an issue earlier since its getting so hot while on charging. Thanks in advance

  • @thesquiggler3323
    @thesquiggler3323 2 роки тому

    So sorry for the long question(s), but I'm having a similar issue with the SMC on my refurbished (late 2009 unibody) Macbook and haven't been able to find anybody that knows anything about this stuff. Anyway, here it is:
    Is it possible to trigger a problem like this while attempting to reset the SMC? I was recently having some software/partition issues (couldn't get past the login screen), but couldn't access recovery mode using command-R for some reason. I was able to access single user mode (using COMMAND + S), so I decided to reset the PRAM, then rebooted and proceeded to attempt to reset the SMC by pressing SHIFT + CONTROL + OPTION + POWER simultaneously (while on the login screen). This powered the computer off, but I was then unable to power it back on. The green indicator light on the magsafe adapter was still glowing at this point. I unplugged the laptop, took the bottom panel off, disconnected the battery and waited ~30 minutes, then plugged the magsafe in while the battery was still disconnected. The laptop still would not power on, and the magsafe light was now off. I re-connected the battery. The laptop still will not power on and the indicator light on the magsafe is now off (it was green before, indicating that the battery is/was fully charged).
    Anyhow... it's been a strange degradation from a minor software bug, to a system management glitch, to possible logic board failure, and it's hard not to feel like my attempts at repair are instead reaping destruction. I've tried numerous fixes suggested on the internet but nothing triggers a response from the computer (no fan spin, no lights.. nothing). Long story short, I think the SMC reset has somehow gotten stuck (in a low voltage state perhaps?) and is preventing the laptop from charging, powering on, etc. Does this seem plausible, and if so, is it necessarily a mainboard issue or is it possible to force the SMC to properly reset by using a different key combo?
    I might try to zoom in on your video and take voltage readings at the same contact points to see if that reveals anything, but I'm kind of at my wit's end here. Any insight/suggestions would be greatly appreciated. Thanks!

  • @skim32
    @skim32 2 роки тому

    Hello. Was hoping you could help me. I was donated a 2015 MBA. The original owner said it stopped working after water damage. When I plug in the magsafe2, no lights. However I see a blinking low battery icon on the screen. I took it apart and when I plug in the magsafe, the fan starts spinning, and again there is the blinking low battery icon on the screen. As a test I tried unplugging the battery. When I do, the laptop starts up and stays on. And all this time, still no light on the magsafe. This laptop can be purchased on ebay for about $120. So I am not trying to spend a lot of money to repair it. Any idea what it might be? Battery? Or something on the logic board? Or maybe the io board?

    Might be a weird question but if the solder joint was partially damaged would that be considered shortening it out? As a mechanic looking at this I would say that the part might be partially damaged or am I incorrect.

    • @Adamant_IT
      @Adamant_IT  3 роки тому +1

      Yea I can't fully explain this behaviour. My best guess is that there was some spray paint on the pins leaking a small amount of current to a ground pin, and it got burnt off in reflow.
      I've seen a straight reflow fix other issues, so the bit about "might not need to replace the part" is based on that - but this partial short was a bit of an oddball example.

    As someone who has done desktop PC maintenance and repair before, I have experienced that there is a short circuit problem on dusty motherboards. After cleaning the dust well many times, the computers were working again. As in the example in this video, the problem is caused by dust. It's not even a bad connection.

  • @Hagledesperado

    Gahd, it was the spray paint, wasn't it. 100k is very weak for a pullup, I would have expected 10k at most. So I have no problem imagining a speck of paint with unknown electrical properties putting up a good fight against it.

      Don't know if you have had any response about your issue but i think the power goes into the trackpad and then back to the main board and gives a signal to turn on . If there is nothing on the return path it will not turn on .
