ProBook 4530s Won't Boot After Sudden Power Failure

[reesejohn69]

Hi,
I'm running Yosemite with Clover on my ProBook 4530s. Couple of hours ago the battery ran out of juice, thus, the machine turned off itself without a proper shut down. Now I can't boot.

I'm getting the following message on verbose mode.

[UPDATE]
It's working now after EC reset!

Boot from USB, repair your disk, run PBI CE again.

Couldn't boot from the USB. Already tried it. EC reset worked, by the way!

Probably unrelated to EC reset. More likely, system was booting without AppleIntelCPUPowerManagement in cache, and thus it was loading from disk post-bootloader. In that case, Clover can't patch it and you get the panic you show in the image.

Fix: Boot without caches. Then repair permissions (just in case), and rebuild cache to place AppleIntelCPUPowerManagement back in cache, so Clover can patch it on normal boot.

Maybe Yosemite decides to boot without caches on its own after a certain number of failed attempts to boot with caches.
