Power Save Mode background task scope for low-traffic workloads

Goal is to reduce resource usage for a low-traffic development workload using IntelliJ IDEA Power Save Mode. The decision is whether the mode provides a predictable cost reduction while keeping essential editing usable.

Planning material references Power Save Mode in the context of background activity reduction, but the exact boundary between suppressed and continuing work is unclear from the available brief. Behavior may differ by IntelliJ IDEA version and by installed plugins, and current external verification is flagged as required.

Uncertainty remains about which tasks are reliably suppressed and which may continue, and how that affects features that depend on inspection data.

Which background tasks are documented as suppressed or continuing when Power Save Mode is enabled in current IntelliJ IDEA? Which plugin categories are considered exempt from suppression? Can suppression be scoped without enabling full indexing and inspections?
