What is the possible status of this MacBook? I tried every single combination and every single way of pressing it, nothing. Long story short, now the MacBook is completely dead, I can no longer able to boot the USB, can't get into diagnostics, CMD+R doesn't work, nothing.Īll of the boot key combos don’t work. So I again pressed the power button to shut it down. The progress bar doesn’t move, the Apple logo stays there for hours.
#TURN OFF MACBOOK POWER CHIME MAC#
Turn on your Mac and immediately press and hold the D key.
The first time it rebooted, I can see the Apple logo and the progress bar, but nothing else. Disconnect all external devices except keyboard, mouse, display, and if applicable, ethernet.
#TURN OFF MACBOOK POWER CHIME INSTALL#
Using Disk Utility, I formatted the SSD and proceeded to clean install macOS High Sierra. I grabbed a USB Stick and made a bootable USB. Then I thought, maybe I should clean install the macOS. When I closed the clamshell and open it again, the black screen was back. When I was finally able to boot into the macOS, the first thing I did was updating the operating system from macOS Sierra to High Sierra (Thinking that maybe it's because of an old OS that needs updating).īut no, the problem was still there. I want to turn the power chime sound off, but cant find a setting. Still just a black screen and repeating chime. Tried the SMC reset and PRAM reset, but nothing has any noticeable effect. Then I tried to boot into safe mode, it sometimes works (I am able to get into the OS in safe mode) but sometimes it just doesn’t work, like the shift button doesn't even respond when I pressed it while the mac is starting up. I then pressed the power button to force it to shut down. a few minutes later I come back and the screen was still black and the fan was spinning so loud. Thinking that maybe it just needs time to boot, I leave it alone. Then I opened the clamshell, and pressed the power button. The charger light comes on, and I left it like that for a few minutes. I grabbed the MagSafe, and plugged it in. I thought it might be just the battery os too low. When I was doing some work, the MacBook shut down when the battery level was at around 20%. Also, I cannot use any boot key combination (except for SMC and PRAM Reset). It's just a blank black screen with a repeating chime. So, my MacBook Air A1465 suddenly fell into a deep 'coma.'
