Dock wake-up test bench

You are a senior product engineer. Turn the product idea below into a locally runnable MVP.

## Idea

Dock wake-up test bench
Runs repeated computer sleep and wake cycles and gives each dock a reliability report.

## Product concept

A remote worker has just bought a dock and connects the computer before the return period ends, then clicks “Run continuous wake test.” The assistant guides them through closing the lid, waiting, unplugging and reconnecting power, and waking the computer for twenty rounds, while recording how many times the display, network, keyboard and mouse, and charging each recover, along with how long recovery takes. After a failure, the user only needs to photograph the dock’s indicator light, and the report preserves the connection state at that moment. When the test ends, it generates an evidence card such as “17 of 20 full wake-ups,” which the user can attach to a return request or firmware feedback. It does not compare advertised specifications; it specifically measures the everyday moments that are most frustrating with docks and hardest to reproduce in reviews.

## Why now (backed by facts)

In July 2026, a hands-on report noted that the same MacBook Pro, ThinkPad, and Thunderbolt 4 dock could still experience intermittent wake failures, while replacing the display made the problem disappear. This shows that reliability depends on the full connection combination, not just the dock’s specifications; at the observation point in the Hacker News signal snapshot, the article had approximately 29 points and 22 comments. Vendor knowledge bases are also still documenting cases where displays, networks, and USB devices are not recognized after waking from sleep. Buyers therefore need repeated validation of their own complete setup during the return period, not another specification sheet.

## Direction (model inference, not independently verified)

Target user: Remote workers who have just bought a dock, display, or new computer and want to confirm before the return period ends that their closed-lid setup wakes reliably. People who encounter intermittent black screens, network loss, or keyboard and mouse failures can also use it to reproduce the problem and leave a record for support.

Minimal entry point: The first version supports one desktop operating system, runs a fixed number of automatic sleep and wake cycles, checks whether the display, network, and USB keyboard and mouse recover, and exports a timestamped success-rate report. A photo of the indicator light is initially a manual attachment for failures.

The strongest case against: The strongest case against this is that operating-system permissions and hardware interfaces may not let ordinary software reliably determine whether charging, the display, and USB peripherals have truly recovered, so the test may still depend on the user confirming each round.

These are the model's inferences from the idea itself and the verified facts. Treat them as directional hypotheses against real constraints: do not assume the strongest counter-argument is already solved, and do not write them into the product as certainty.

## Punching above weight (model inference)

Create indexable test pages and anonymized device reports around specific fault terms such as “dock model + display stays dark after sleep” and “Ethernet not detected after sleep,” then share reproducible reports on Hacker News, Thunderbolt and USB-C communities, and vendor support forums.

## Competitors & gaps (model inference)

- Windows Hardware Lab Kit（HLK）: Windows HLK can run device reliability tests that include Sleep with I/O, but it targets hardware manufacturers and driver developers and has high deployment requirements. This idea reduces the test to a single-computer workflow that ordinary buyers can run during the return period.
- Vendor Support Knowledge Bases and Manual Troubleshooting: Dell, Plugable, and other vendors already provide knowledge-base articles and troubleshooting steps for dock wake failures, but they mainly address problems after they occur. This idea fills the gap by running proactive repeated tests and organizing display, network, peripheral, and charging recovery into a submit-ready result.

## How it makes money (model inference)

One-time desktop purchase. Free users can run a small number of tests; paid users unlock full cycles, history, and exportable evidence reports.

## Signal background

Theme: Reliably waking docks
Trigger Hacker News post (original English): A dock that wakes up reliably
Heat at capture: ~29 points, 22 comments (point-in-time values)

The signal data is a historical snapshot from the moment it was captured; heat values drift over time and only explain “why now.” Do not write them into product copy as precise market numbers.

## Deliverables

- Before you start, distill 3–5 verifiable acceptance criteria from the concept and minimal entry point above, list them, and walk through them one by one on delivery.
- Ship the core flow described by the minimal entry point first, so the core user can get through it; leave out generic systems (accounts, payments, admin) unless they are truly necessary.
- Do not show unverified market numbers in the UI or API.
- Keep key copy calm and verifiable; when the product needs domain facts or safety guidance, adapt them from the Sources list or equivalent authoritative pages and cite them — do not write them from general knowledge.
- If building inside an existing project: read the README, dependencies and conventions first; follow the existing stack and style, and do not refactor unrelated code.
- If the current directory is empty: pick a lightweight stack and prioritize a runnable prototype.
- When done, explain what changed, how to run it, and how to verify it.
- Ask only when an ambiguity would genuinely change the product direction; make ordinary implementation calls yourself.
