Won't power up after hard drive swap
I cloned/swapped my old hard drive to a 1TB HD, booted from the new drive through a SATA>USB adapter, shut down, and installed the new hard drive.
That's when things got weird. It wouldn't boot from the new drive, leaving me with the flashing "?" folder image a few moments after the boot noise. No boot in recovery mode, no option boot.
So I cracked it back open to check my connections. Unplugged keyboard, then I realized the power adapter was still in. My heart sank. Since that moment, I haven't been able to boot from any drive, or even get the machine to power on.
Keyboard ribbon connector is snug, and the ribbon seems undamaged after close scrutiny. I tried a pram and smc reset, but the keyboard doesn't even seem to be getting power.
I don't want to spend much more money on an 8 year old machine, but I don't want to scrap it unless I know for sure it's toast. Is there a way to boot this sucker?
UPDATE: Anyone else who made this mistake and can't make their machine take power, disconnect your pram battery and reconnect it. The machine should now take power and boot again.
Be sure not to pop the pram battery connector off the motherboard entirely- it's a relatively common mistake, and non-fatal- but it makes your computer take much longer to boot from a dead battery.
Is this a good question?
