Hello All, My MacBook air randomly sleep and shut of. It was working fine until i keept it to download the latest Xcode from the app store after installing it the device is always sleep and shut of randomly. I tried to reset the SMC many time without any hope. Also I have read old post here talking about the liquid damage after it i have opened my device and i found that everything is clear and fine. Sometime about 2% the devices working fine without doing anything and 98% it randomly sleep i just discovered that the device going to sleep or shut of if i’m not using the keyboard or the touchpad but while i’m using the touchpad or keyboard the device working well. [Update] Sometimes i got this message when i handoff the keyboard or touchpad.
Besides, I have OSX 10.12 and I joined the public beta program to get the latest OS but i faced very weird issue that after downloading the updated and in the installation phase i got a massage that the system can’t verify my device !!! and i can’t install the update.
Please note: that my battery are working fine without any problem and i have visited the Apple service centre in Egypt and they failed to understand the issue. [Update 23rd October] when i try to reinstall the SMC firmware i got this message. I’m sure that this is the correct firmware i downloaded it from apple support website.
Thanks,
To see if it is a software issue, boot up in Safe Mode by holding down the Shift key on boot up.
Hi, It is an issue with the keyboard, where it is triggering the power button by itself (sometimes holding it down, sometimes just pressing it). I have come across this a few times with MBAs, usually caused by a small amount of liquid. Remove the bottom cover, battery, and disconnect the keyboard. Then boot it with the keyboard disconnected (it will boot automatically when the charger is plugged in). If you no longer have the issue, the keyboard will need replacing.
