What you will submit
A single shared link or document containing the fault diagnosis, the step-by-step fix with parts and tools, the realistic naira parts costs, and a professional customer quote for one laptop.
What to do, step by step
- Choose a real faulty laptop you can access, or a clearly described sample one. Record its brand, model, age and the exact symptoms, and write down the customer's story (what happened, when it started — did it fall, get wet, suffer a NEPA surge, or slow down gradually?).
- Document your diagnosis: explain step by step how you worked out the fault, how you separated hardware from software (e.g. BIOS or USB-boot test, swapping a known-good charger, reseating RAM, checking with an external monitor), and state your confirmed conclusion. Note the static and battery safety steps you took.
- Lay out the fix: the exact parts needed (with the precise spec — screen part number, RAM type, SSD slot type or battery model as relevant) and the tools used, then the step-by-step repair or upgrade procedure including any data backup you would do first.
- Source the parts realistically: state where you'd buy them (Computer Village or your local cluster) and the realistic 2026 naira cost of each part, noting whether it's genuine, a good clone or used, and any market traps you'd avoid.
- Write a professional customer quote: the part(s) with your markup, a separate labour figure, any diagnosis fee, your deposit terms, a short warranty, and a clear naira grand total — plus an honest note on data risk and aftercare advice.
- Combine the case story, diagnosis, fix, parts list and quote into a single shareable document or link (Google Doc, PDF or image set) you could genuinely hand to a paying customer.

| Criterion | Weight |
|---|---|
| Diagnosis: clear, methodical reasoning that correctly separates hardware from software using real tests (BIOS/USB-boot, charger/RAM swap, external monitor), with a justified conclusion | 30% |
| Fix and parts: correct exact-match part spec (screen part number, RAM type, SSD slot, battery model as relevant), a sound step-by-step procedure, and the right safety steps (static, disconnect battery, data backup) | 25% |
| Professional quote: itemised part(s) + markup + labour + any diagnosis fee, deposit terms, warranty and a correct naira grand total | 20% |
| Nigerian context and realism: realistic 2026 naira figures, Computer Village/local sourcing with clone-vs-genuine awareness, and honest data-risk and aftercare notes | 15% |
| Clarity and professionalism: the document is neat, well-organised and genuinely presentable to a paying customer | 10% |
You need 65% overall to pass. A failed submission comes back with feedback and can be revised and resubmitted.
Before you submit: make your link public
If your work lives in Google Drive or Google Docs, open Share → General access and change “Restricted” to “Anyone with the link” (Viewer). Then paste the link into a private browser window: if it opens without sign-in, you are ready. A private link cannot be graded — it is the single most common reason a good project fails.
Frequently asked questions
Do I have to finish Laptop Repair Basics before submitting the project?
Yes. The submission screen opens once every lesson in Laptop Repair Basics is marked complete. The lessons are where the methods, the Nigerian context and the worked examples the project depends on are taught.
How is the project graded?
An examiner scores each rubric criterion from 0 to 100 and weights them as shown on this page; you need 65% overall to pass. Most submissions are graded within minutes and you get written feedback on what was strong and what to improve.
Can I resubmit if I fail?
Yes. A failed project comes back with feedback; revise the weak parts and resubmit. A passed project is final — the certificate is issued and cannot be re-rolled.
What do I actually submit?
A write-up of what you did (under 5,000 characters) plus a public link to your work — a Google Drive folder, Google Doc, spreadsheet, GitHub repository or video. The link must open without sign-in; a private link cannot be graded. The free project workbook on this page walks you through all 6 steps.
Is the certificate real?
Yes. Passing this project issues a certificate with a unique verification code. Anyone — an employer, a client, a school — can open the verification page and see that the certificate is genuine and which project earned it.
