My husband’s elderly MacBook Pro keeps restarting but refuses to boot. We’d like to be able to keep it going until the next models are released, which should be soon. Here’s a summary of what’s going on:
I have a seven year old laptop that refuses to boot. It’s a MacBook Pro8,2
with a Quad-core Intel Core i7 CPU running the latest version of Sierra.
The reboot issues arose a few weeks ago when the laptop began needing
several tries (i.e., repeated self-reboots) to start up after I initially
pressed the power button. Now, nothing. The Apple logo and the progress
bar come on, the screen goes gray, then black, the laptop restarts, and
the non-booting sequence begins again, and again and again…
I’ve tried booting from Leopard and Snow Leopard install discs, holding
down the C key upon restart after sliding the discs in. After a few
moments, the CD drive ejects them before the computer has had a chance to
read them. I’ve also tried holding down the option key upon restart in an
attempt to boot from the hard drive image, which does display on the
screen along with a menu for selecting a Wi-Fi network. But, clicking
start only triggers the sequence described above.
I’ve also tried the remote hardware diagnostic test (holding down D upon
startup) in both basic and extended mode, only to be informed that there
are no issues with the hardware. I’ve even tried resetting the PRAM. No
I’m not sure how to proceed and would be grateful for any advice.
Fortunately, the laptop is fully backed up to an external drive as of when
the reboot problem first surfaced. The only other thing that seems worth
mentioning is that the trackpad on this machine hasn’t worked for several
years. It’s jammed from what I assume is a swollen battery inside the
My MacBook Pro is even older, and also has aswollen battery, so even though mine boots OK, I’d like to be able to keep it on life support until the next generation is released as well. Any suggestions as to what might help will be much appreciated.
