#1234 — Reset password after losing power during a decade old MacBook Pro (MBP) boot up after entering a password for its internal HDD?

Hello.

Here's a weird one. I don't know if this is by design. I was booting up 
a 2008's 15" MacBook Pro. I already entered its HDD's FileVault password 
to slowly boot up its updated Mac OS X El Capitan v10.11.6. And then, I 
accidently pulled its mag power plug from MBP and the system shut down 
(sleep?) due to lack of power (still using the original battery -- never 
replaced any hardwares on it since it is rarely used).

After replugging its power plug back in and turning it back on, it did 
its usual slow boot up but it never asked me to enter my password to 
access its encrypted HDD. Instead it took me to its password reset 
screen with three prompts. Huh? I never asked for that.

Was that supposed to happen?

That battery should probably be replaced pronto.

You mean this screen?:

<https://support.apple.com/library/content/dam/edam/applecare/images/en_US/osx/yosemite-password_reset-choose_problem.png>

That's normally what you see when you let the computer sit at the
FileVault password entry screen for a while, and the computer guesses
that you may have forgotten the password to FileVault. It tells you that
you can hold the power button to shit down, then press the power button
again to boot up into macOS Recovery, where you see this screen. So
apparently your computer booted into macOS Recovery due to losing power.

I haven't ever arrived there by accident, but I suspect you can just
shut it down and boot it up again to get back to the normal boot
sequence.

Why? Is it bad? Will it blow up? This MBP is rarely used since it is 
very slow and old. :/

Yes, that's the screen.

Ah. How long is the wait before the computer bring this FileVault reset 
password screen up? I didn't wait very long since I only powered it back 
up from an accidental shut down during its boot up. I wonder if it just 
went to sleep due to lack of power and then came back to this, but then 
its boot up was slow (normal) after its power loss.

Yes, I was looking a way out and saw a reboot/shut(not shit) down 
option. ;)

Oh well, I was just wondering. No big deal. I was just wanted to know 
if that was even normal. If it was, then it would be a weird design! :)

Because of what *just* *happened* with it. If you accidentally unplug it
while it's running, you risk data loss/corruption. If you don't care
about data corruption, fine. Dying batteries can also swell and leak,
which can cause damage to other internal components. You may or may not
notice that happening before the damage occurs, but you also might not.
If you don't care about that either, fine. It's your computer. Do
whatever you want.

I don't know. If you really want to know, try it out for yourself. Boot
it up to the FileVault login screen, then let it sit while you time it.

It had to check the integrity of the disk (see my previous comment about
data loss/corruption). It'd be a good idea for you to run Disk Utility's
Verify Disk facility - Unless you don't care. Then do whatever you want.
