Scope and coverage
Choose your exact model to see current coverage. The library currently contains 2700 guides for 327 exact reviewed models. Other reviewed models remain searchable and receive an honest “no matching guide” result when no procedure applies.
The checks use manufacturer or platform documentation. Separately labelled owner reports help us choose useful checks and explain real-world uncertainties; they do not prove a cause or a cure. These procedures are not our physical tests, even where a linked review is hands-on. If a required menu, version or condition is unknown, follow the unknown branch.

Unknown details remain unknown. Finishing the steps is separate from reporting that a problem is solved. A changed or withdrawn guide cannot silently resume an old procedure.
