GUIDE
1. Record the power-button indicator at the event. The guide identifies steady on as on, slow blinking as sleep, and off as off or hibernation; off alone does not distinguish those last two states.

2. Review Windows power settings and the configured power-button/lid behavior without changing a managed plan. The computer’s actual settings determine the comparison; a closed lid is not proof it slept.

3. Save work, safely remove the dock/peripherals, and choose Windows Start → Power → Sleep when available. Record the indicator and whether an ordinary brief power-button press resumes work.

4. If safe, compare another ordinary event using the documented dock setup or a later direct baseline. Keep the selected power plan and workload constant. Record each actual event instead of repeatedly forcing failure.

5. If a normal resume fails and a forced shutdown is needed, stop repeated testing. Retain indicator, power source, accessory state and backup availability for Lenovo/IT.

EVIDENCE TO RECORD
Indicator during event: Not recorded
Sleep entry: Not recorded
Resume result: Not recorded
Accessory condition: Not recorded
Direct baseline — Saved work, no dock, known power plan: Not checked
Documented dock condition — Same plan/workload, compatible dock: Not checked
Later direct observation — Original baseline during normal use: Not checked

STOP CONDITIONS
Stop using and charging equipment with swelling, casing separation, smoke, a burning smell or suspected battery damage. Do not open or press on it.
Set damaged accessories aside. Do not open mains adapters or force connectors.
Do not erase, reset, flash firmware or bypass a lock as a default diagnostic step.

OUTCOMES
Resume observations saved: The recorded events resumed normally; preserve the original symptom and conditions.
- Retain indicator state with each event.
- Use later ordinary events to report recurrence.
Review the dock-specific resume condition: The direct baseline and dock condition differ.
- Give Lenovo/dock support the two event conditions.
- Keep dock firmware or driver changes a separate supported decision.
Keep the sleep comparison incomplete: Sleep was unavailable, work was active, or comparable events are missing.
- Record the power plan/policy availability.
- Leave omitted conditions Not tested.
Request resume support: Normal resume failed or forced shutdown became necessary.
- Provide indicator, power source, dock state and recovery type.
- Preserve accessible data and stop repeated forced cycling.
Keep the unanswered checks visible: Sleep entry, indicator state or normal-resume result is unconfirmed.
- Share power-button indicator and actual resume behavior.
- List power/accessory conditions and any forced shutdown.
- Keep unperformed conditions marked Not tested. Ask the provider to confirm these before further changes.
Stop the powered checks: Stop using or charging damaged equipment. Keep away from hot or smoking equipment; obtain emergency help for an immediate fire risk. Arrange manufacturer guidance before handling or transport.
- Tell Lenovo or your IT team about the visible damage before arranging transport.
- Share power-button indicator and actual resume behavior.
- Do not open the case, remove the battery, press a lifted surface, or continue a test to complete this record.
