How do I split a Repair Guide into prerequisite components?

How do I split steps out of a guide and put them into a new guide?

The HF35xx Disassembly originally included not only opening the housing but removing one of the internal components (inner lamp). I continued that structure in describing how another component could be removed (main PCB).

However, it doesn't make sense to do it that way since the same steps are referenced as a prerequisite in a the HF3520 Power Supply Repair guide which needs to remove the main PCB, not the internal lamp.

Ideally, I'd like to structure the prerequisite dependencies something like this:

  1. Disassembly: Should only have steps for opening the housing
  2. Main PCB Removal: Depends on Disassembly
  3. µC Board Removal: Depends on Main PCB Removal
  4. VE Board Removal: Depends on Main PCB Removal
  5. VE Capacitor Repair: Depends on VE Board Removal
  6. Lamp Removal: Depends on VE Board Removal
  7. Control Panel: Depends on µC Board Removal and VE Board Removal
  8. Power Supply Repair: Depends on Main PCB Removal
  9. Speaker Repair: Depends on Disassembly
  10. Power Jack Repair: Depends on Main PCB Removal

I'm going to use the T420 guides I did this on as my example.

For the keyboard guide:

Hard drive:

Memory:

Take the images (and steps) from the main guide, then rework them into prereqs similar to how I reworked the T420 guides into something usable.

Okay, I think I get it now. Are there buttons that I cannot see due to lack of reputation that would make splitting a guide easier? For example, a "Duplicate Guide" option would be great.

@hackerb9 That's an admin only thing.

@nick Thanks. That's discouraging, but understandable. I presume "Duplicate" is like "Revert" where it publishes the changes immediately instead of adding the new guides to the patrol queue, right?

@nick Hey Nick, I had a little trouble understanding the prereqs in your answer because my browser only shows the beginning part of each URL. So, I made a graph of it to help me understand. I've made it an answer so maybe it can help other people in the future. Please let me know if I misunderstood what you said, though.

by

@hackerb9 You got it right. There's one weird guide in there I didn't prereq the reinstall guide as I just let it live as a link.

As an example, Nick's T420 guide has the following prerequisites:

Keyboard -> Keyboard_FRU;

Keyboard -> Battery;

Hard_Drive -> Battery;

Memory -> Battery;

Memory -> Keyboard;

Memory -> RAM_Bottom;

Memory -> RAM_Keyboard;

Shown graphically, that would be:

Note that prerequisites are not recursive. The Memory guide depends on doing the Keyboard step first, but it does not depend upon Keyboard_FRU which is why Nick split it into a separate step.

That means the example graph given in the question is incorrect because each guide must explicitly specify all prerequisites. It ought to look like this:

As for tools, iFixit's software does not yet give regular users an easy way to split a guide into parts. Admins can duplicate a guide and remove the overlap, but most people will have to manually create a new guide and move the content piece by piece.

I actually created a one step guide for the FRU info. I could have duplicated it and cleaned it up as I needed but it was more efficient that way.

https://www.ifixit.com/Guide/ThinkPad+T4... - not sure if this fits your example well but I had to split things up for the reverse steps as a elimination for confusion. It's not a added prereq, more of a hidden guide.
