I know the reset worked, because the light on the adaptor did change color for a second…but nothing. Let the Mac boot up as far as it can, then enter the password and hit return. Anybody got a solution? The MacBook air 11 inch still runs terribly slow. The symptoms certainly seem to point to SMC but doing the reset as mentioned above does not work. Is there any other way to reset it? If I shine a light in the back I see files but no cursot. My Macbook pro cant even show a black or blue screen, no beep, it seems completely dead.
It can only show a green light on the charger and can blink green on the machine if I remove the charger. That is the only life it seems to have. Tried everything still have a black screen including PRAM reset. Any help much appreciated As travelling. This morning, I put my mac to sleep and the screen stayed black despite hearing the startup bell. I followed the instruction pressed the 4 keys together for a few second, then released them together, before pressing the Power button on the top right and like magic, the screen was back on.
Thank you for helping me out. My fans were running constantly and Bluetooth hardware could not be found. Did as instructed on my iMac and it is magically back to normal. Thought I was going to have to carry my machine miles to the nearest service center. I am so happy this worked. Thanks for the article! In case if you are using 5ghz, I would check the band. Mac book pro doesnt support all the 5Ghz bands. All my problems fans run constantly at high speed and general performance is slow were fixed when reset SMC Macbook Air.
Fixed a persistent issue of needing to start in safe mode. I ran disk utility many times without any progress. I have had problems with my DVD starting and ejecting, lately. This site solved my problem on my iMac with its suggestions on resetting the SMC.
The DVD started up and ejected when done. I put it in the box until March then took it to Apple Store where it powered on to my surprise. It powered right up where it left off back in May. Thank you very much for the info. It took the rest of the day to do all the updates through installation of lattest operating system Yosemite. Sometimes it can corrupt and cause random hardware issues. My MacBook Pro was booting to black screen.
But this time it was this trick. For people not understanding the instructions, you press those buttons, and yes, there is no feedback! This time no black screen. What is this actually doing?!?!?!!!!! I reset the SMC twice in the last two weeks because the laptop works fine for a little while after doing it.
But after using it for a few days, it gets weird again. It starts with the fans running very high when charging the battery and it could just turn off suddenly at any moment. Any ideas? Do I have to keep resetting the SMC once a week? Great website, by the way. Thx a lot for this manual. I was running FileVault to save my files, but because I had wrong rights filevault terminates my Mac, so that it freezes and nothing more was working. After a hard reset and after trying to reboot from the recovery it only came the internet recovery option.
Nearly on the way to the Apple store. Could be that the hard drive is dead. I read your explanation of the smc reset. I tried, because it was my last chance. Done and rebooted into the recovery section with the harddiskrepair. Checked the harddisk…seems okay, but the rights are wrong. Trying now to fix the issue and maybe then I will have the chance to unlock the data.
I will see, because decrypted not really much. Maybe I have a chance. But without your help I will be now at the Apple store and bought me a new hard drive or ship it to the care center. Thx from Germany!!! You saved my day. I tried to just push them, I tried to hold them down for a little while… how do i understand that the SMC has indeed been reseted?
A beep? A light? Any sign at all? Im having the same problem. Im pretty sure my mac is not reseting the SMC because the energy setting had not reset. Is there anything else i can do? Well, I started getting these restart messages every time my computer did start working, and had to keep doing this until the computer just gets stuck at the white loading screen with a grey spinning wheel under an apple sign grey also, this computer has the rounded edges and no, does not have the removable battery.
If following these directions does not work, try powering down, unplugging, then doing the shift, control, option, power thing then restart. Thank you so much. MacBook 1,1 Intel Core Duo. Apple is doing their best to deny replacing the ruined batteries but at some point the pressure from customers will make them face this issue, or litigation will. I have a macbook pro 17 inch running Yosemite for awhile everything ok. Replace the battery, reconnect power, and zap PRAM and wait for 2 chimes before letting the keys go.
