Changed for another new battery, seemed to have greater capacity according to System Parameters software and much greater discharge time. Went through Battery Calibration process. All seemed well. Installed remaining battery screws and back cover. Tried to start up; nothing. No light, no fans, nothing. Removed screws until the last known working conditions were duplicated; no change.
SOLVED: USB connection problem with iPhone - MacBook Air 13" Early - iFixit
Went through all processes suggested in above article, still nothing. Battery voltage at first 9-pin motherboard connector is Anyone have any suggestions? It did not resuscitate. Thanks for the tips. Memory is fine. The SSD is fine. But my Macintosh HD partition the whole drive cannot be repaired, evidently. I am not sure what the problem could be.
My mid MacBook pro will start and boot up but only after about minutes of holding and releasing the power button. It works fine after it finally starts. It gets power just fine and I can see the power light come on everytime I hold and release the power button. I have no idea what to do. Please help! My MacBook Pro was brought to life again. After it tried rebooting after an update, it wouldn't turn on again. Just a very short "bssshhhhrrrttttffffrrrpppp" the sound it makes at boot up, like it's about to throw up and the front indicator went out again.
My Mac Pro worked until I updated the os to high Sierra. The Mac kept displaying something to do wth ICloud. When it is switched on the screen awakens, the Apple logo appears, the progress bar starts, very very very slowly proceeds but that is as far as we get. No further. You might consider reinstalling the operating system.
That should provide a boot up menu either from your computer HD or another HD that you use as a backup. Options should include restoring a prior backup or reinstalling the operating system. Some of these options may delete personal files so use at your own risk. Thank you so much for your website! Awesome stuff! Your instructions were really instructive and clear. Just by following your steps, I managed to get my crashed macbook back to health very fast well, 3 hours, but that is faster than sending it to the Apple workshop.
Thank you so much! I turn off myMacBook Pro and when I turn back on, I get the apple with black line inching its way to the end. Gets to the end and does nothing. I ran the hardware diagnostics and it said No Problem found. Me too. Disk First Aid showed my hard drive as being completely full. I'm going to try and delete some files and see what happens. Reset the SMC and the PRAM as you suggested above on my daughters 'dead for a year' macbook pro and it is currently running and happily backing up its files. We shall see how stable it is before jumping for joy!
Using a MacBook I know only 2 yrs old! Last week it shut off while I was using it. Thought a power glitch, restarted but it was stuck in a loop. Moments after showing the Apple ID screen, it shut off, sounded the chime and over and over it went. Tried all the suggestions you recommended. Files all said ok, only problem it said was an issue with the camera. Yea it booted up and I saved data to a jump drive. Worked fine for several days then it shut off again. Now none of the above have an effect - just chime and loop. Took it to India this summer had a few power glitches there, destroyed a kindle fire and curling iron, scared something happened to my Mac.
It has had a few problems since I got back, had to reinstall Office.
Any help, please.? Thank you so much for this article. I have never heard of you or this website, but a quick Google search on my phone led me here.
iPhone won't charge or connect to Mac! Oh no!
I had physically shut my laptop while installing the new update. This saved me valuable hours and a trip to the apple store. I am typing this review on my laptop now because of you. Again, thank you a bunch. Great article. Thanks to this article I was able to open recovery partition. My main drive macintosh was grey and I could not run first aid on it. It also wasn't listed as a location to reinstall OS. I am backing up right now just in case this happens again!
Macbook pro 15" retina, purchased in fall of for anyone interested. Hi thank you for an excellent article. Nice to see a Vancouver ite so active. My problem is with a Mac desk top but the suggestions you make apply to the top as well. I found the s that came with the computer. I put in the Hardware disk and sure enough, miraculously, after pressing ''D key up came the Hardware Test screen. I pushed the Test box button and left the computer to do its test. After 4 hours the progress bar was within a centimeter of the end.
But there it stayed even afetr leaving it overnight. What to do now? Any ideas would be most appreciated. Retired Apple Certified Tech. A friend's 15" MBP non-removeable battery would only flash led for a second and run fans for a second. Thanks much. You made me look smrt. Hi, thank you for posting this. Older MBP. I was getting anxious as I tried everything until I got towards the bottom of the list.
The recovery partition worked! I used a recent time machine backup. I fixed myself although only with the guidance of your article. Thank you for sharing this. Not sure which one worked but my mac is back- thanks for a great article - best I read on the web. I thought I tried everything to get mine to turn on and found this article and did the holding down the power button 10 seconds twice and then the third time plugged the power cord in and pressed the power button and it finally booted up!
Thank you for the trick!! Unplug the MagSafe power cable. Hold down the power button for about 10 seconds and continue to do that. While still holding the power button down, insert the MagSafe power cable and hold it for another 10 sec. And it started right up. I thought that was a crazy thing to do and how did anyone ever discover that it worked???
But it sur did the job on this laptop I managed to switched it on, where my user login logo appeared, but then a loading bar would appear and just freeze. Then I found your link, which made my day! Happy Mac again. Thank you!! Thank you for posting this: - My problem started this am with a very slow IMAC that has 16 RAM , and a time machine attached; - Several warm and cold reboots brought the system totally to its knees, and then it stopped rebooting half-way through the process; - option D during reboot brought me to an error screen D, maybe?
I updated it to macOS Sierra yesterday night and left it be, when I opened it the next day it wouldn't continue starting up. Please help. I can send you the picture of what it's showing me now. Been trying several tips but nothing is working. Remember the reason you wrote this article, and why I wasted my time reading it, was because my computer wasn't starting up. At all! I reinstalled the OS as a clean install over the top of an install from Time machine.
Problem is it won't wake properly from sleep. Sometimes I get the log in screen - where password is required - and having input the password the same screen the appears again, When I input password for the second time it then lets me in and generally gives me the pages left open when put into sleep mode. It's so frustrating and bizzare behaviour. Disk utility tells me there is nothing wrong Any thoughts welcome. I did the power cycle tip too and it worked. Mine is a vintage one already.
2. Run a Power Cycle
I used to leave it on Sleep mode most of the time while connected on the charger. I'm not sure if that was the reason why the second I open it, it won't boot successfully. I'm worried about the files I just transferred from my phone but thankfully it opened so I'll go ahead and retrieve them back for safety. Thanks again! I followed the power cycle reboot steps and got my mac to give me signs of life and then when it died in the middle of boot I restarted the process and plugged the battery in the middle because I only have a 60w power supply and needed an 85w.
I used the battery as a wattage boost in the middle and got my computer back up and running. Thanks for the guidance. My Mac Pro late , non removable battery behaves strangely. It does not switch on at all. Battery shows fully charged when I check by small side switch. Now, If I remove adapter connector, Mac starts up. But no chime. Before it completes booting it shuts down. Restarts on its own after sometime. On restarting same thing is repeated.
Any suggestions please Black screen, L-type chord shows a charge going on orange light , fan whirring. No other signs of life. No start up chime, no matter how many times I hard power down and restart. It's a MacBook pro with a non removable battery. Hi Fennelly.
I have the same issues right now. Did you manage to bring back your computer back too life? Holy Bologna!!! I was convinced my MacBook Pro was toast. The special Poeer cycle seemed Compliments on the well structured and informative guide! Started using a Macbook Pro Md for a week or so now, when it just turned off. At the istore they performed a SMC and run a diagnostic check - proclaiming all is fine. A day after it happened again. Thank you kindly. Great guide, I have no Mac experience and was able to repair my son's Mac using your guide. After hours of trying everybody else's suggestions I fixed me problems with your pointers!!!
It took many layers of fixes but eventually sorted out my MacBook. I luv u?????? You are awesome! I reset the PRAM and it booted up quickly. Worked like a charm. You are the best. Thank you.
USB connection problem with iPhone
The first solution worked for me!! The fan seems to be a lot louder.. But my MacBook is up and running. Thanks so much, Jessica and to Victor Clausson for the "special power cycle" tip. Thanks Jessica! But even after all the El Cap troubleshooting, I've still been stuck! Then, a little comment from you and I was digging into RAM at the same time, but getting no love : It's the memory sticks. Thank you, thank you, thank you! I thought you were nuts. Unplug the power and hold down the button?
Reattach the power and keep holding the button down? What was that possibly going to accomplish? Have appt Apple Store in 1hr!! Been having battery problems within my Apple Care but store refused to do anything; kept doing diagnostic, all extras……???????? I didn't remove my partition with the OSX install - I just can't access it! I don't know what to do. I have replaced the old keyboard thinking it might be problem with the new one. Hi, I'm happy all other users solved their problems with Mac.. But, My problem seems a bit complected..
But still get White Screen after chime Sound Non of the startup combinations or shutdown work Any suggestion would be great Thank you.. Three days ago, I plugged the Macbook early into the socket to charge. The next day when I turned it on - nothing happened. No chime, no screen, nothing. Took it to Mac Genius which was a waste of time, took it to an Apple approved repair shop, they said the keyboard was clearly full of water impossible , had a technician visit the house and test, doing all the magic tricks you can do to wake up a mac, nothing worked - everyone said it's the logic board.
I have had this Macbook purchased new only 2. It didn't make sense that this essential and most expensive part of the MBP would die so soon. I had suspected the battery as responsible for some time for other issues erratic track pad for example. I backed up the computer, turned it off - no problem rebooting at all. And in fact the computer is working much faster now.
I will have it totally checked out and replace the battery 38 euros. When trying to charge my iPhone 5s in my macbook air it just connects and disconnects all the time. It's like the macbook can't recognize it for longer then half a second. When connecting my external harddrive i noticed that the same problem occures but not at the same rate.
The external hard drive can be connected for a couple of minutes before disconnecting. Charging the macbook works okay but noticed the other day that it suddenly stopped charging. But the iPhone is the biggest problem. The charger works just fine when connected to the wall so I'm quite sure the problem is with the computer. I think the way to solve it is to reset the SMC but wanted to check here first to see if someone has another solution before doing so.
- take a picture on a mac without photobooth.
- download ie for mac 5.2.3!
- mac os x mavericks path variable.
Anyone else had this problem? Posted on Jun 6, PM. Oct 20, PM in response to ms. I just saw this because I began having this issue, but for anyone after me looking for answers, I fixed my issue my taking the ends of a tooth brush and bare with me lightly rubbing it into the ports on my laptop to get rid of all the excess lint built up and it works perfectly fine. Oct 20, PM. Page content loaded. Jun 6, PM in response to ms. You need to use the charger that came with your iPhone. The USB ports do not provide sufficient power to charge the phone. Jun 6, PM. I'm using the charger that came with the phone.
Why haven't you taken it to an Apple vendor to see about getting it fixed? Why have you waited two months?
