If you've few technical skills or have some, you could remove the HDD
from failed MacBook (older ones are easier than even older PowerBook)
by using free iFixit guide for MacBook (circa 2006~2010) or MBook/Pro
or MBk/Air from their site online; identification is helpful...
If just a simple MacBook, look through here and identify the model which
matches the failed unit (or look into similar product models and see how
most likely you'd remove the hard drive.) They are enough alike to do this...
only Four of Seven guides listed are for 'earlier' MacBook 13" 2006-2010
other links to all the additional macbook/named product guides:
If you want to pay someone else to open a failed MacBook, to try & get
access to the internal hard drive, there are Apple Authorized Services
and those providers can do various tasks for a fee.
There's a 'universal drive adapter' that attaches to bare drives, has its own
power adapter and comes with wires to connect the HDD to USB cable.
An example of this great idea is from this maker & mac-centric vendor:
NewerTech Universal Drive Adapter USB Bare Drive Adapter
So this is a good product to own because it helps you format a new HD
or SSD, and access failed non-bootable hard drives; can be a first-effort
instead of paying recovery services for your files. {Once out of failed Mac
there are free utilities that could be used to try to get other files.} ~ You'd
need a separate external drive ideally, to archive additional saved content.
