It's not possible. From OSXDaily Where’s the Startup Boot Sound on New iMac & MacBook Pro? One theory promoted online and originating from some web forums was that you could re-enable the Mac startup chime sound effect by turning to the command line. The claim was that by launching Terminal app and entering the following command syntax: sudo ...

The problem was a faulty hard drive connector cable. I ordered a replacement from iFixIt and the laptop is functioning again.

It sounds like you updated the firmware on the video card. The drive selection screen and other startup keystrokes work from the original EFI. This likely happened when updating W10. You may have accidentally also updated a video driver that included a VC firmware update. Been there, done that. Getting the card re-flashed to the Apple VC EFI is likely to be ...

If you iPad is currently spinning trying to boot and you don’t have access to the power button there isn’t much you can do at the moment. Hopefully allowing you Device to continue to try to boot will drain the batteries. This will allow your device to shut down, then start charging and hopefully it will boot up. Start charging with your computer so you can ...

This can be a software issue or a combination of software issues. But if the power button could not work it cant be put into recovery mode or DFU mode. Or you couldn't force start it. Did you check it while charging cable attached? The thing is this device is so old so there are not many things that can be done. So I guess if it does not start its own. Its ...

I would try plugging it into your computer to see if it's recognized by iTunes or your computer in general. Outside of that, you'd most likely need to visit an Apple Store or an Apple Authorized Service Provider, as you would most likely need a unit replacement or a button replacement.

I found this way to keep Facetime from running at startup. Since it's a rather insidious program, you have to take much more drastic steps to force this program to play nicely. There is a .plist file that can cause Facetime to run during startup. Delete that file, and it should no longer start automatically. It should still run normally if you want (by ...

While the "Unsupported CPU" and "Unsupported PCH" messages in the log appear concerning, I wouldn't jump to the conclusion that this is what's causing the problem. The fact is I've seen these messages before in Macs that run perfectly fine. I see you've already reset the SMC, but you haven't mentioned resetting the NVRAM and this is something you should ...

As @bmike mentions, the issue is the nvidia GPU. The early 2008 MacBook Pro was later covered under an Apple repair program due to the common event of its nvidia GPU failure. More on that here. Sadly, the machine is well outside the terms of the repair program by now. To be absolutely certain of GPU failure, connect the computer to an external monitor ...

Those visual artifacts are very typical of a failing GPU. This looks pretty advanced and you can usually confirm by seeing an external display fail as well. It could be cabling or the LCD, but that’s far less likely. Super rare would be driver or software issue. Make sure you have a good backup in case when the GPU fails it takes down the logic board as ...

Try this... (resetting the SMC) This is how to reset SMC on most modern Mac laptops, none of which have a removable battery: Shutdown your MacBook Air / MacBook Pro Connect the power adapter to the Mac On the MacBook / Pro’s keyboard, hold down the Shift+Control+Option keys and the Power button at the same time Release all keys and the power button at the ...
