Lenovo Support — Find Repair Guides, Parts, Drivers & Warranty

Purpose

Resolve a Lenovo product identifier (machine type like 21ML/20VE, serial number like PF2W2GLT, or marketing name like "ThinkPad T14 Gen 5") to its canonical pcsupport.lenovo.com slug, then enumerate the artifacts a repair tech actually needs: Hardware Maintenance Manual (HMM) PDF, part numbers (FRU/CRU), driver downloads, BIOS/UEFI updates, diagnostic tools, warranty status, and the Self-Repair Guide (ThinkPad/ThinkCentre/ThinkStation only). Read-only — never click "Order Part", "Start Repair", or warranty-claim CTAs.

When to Use

• Repair-shop or IT-admin agent loading the HMM PDF for a specific machine before opening the chassis.
• Pulling the latest BIOS/UEFI for a fleet machine.
• Looking up a CRU/FRU part number from a serial.
• Triage workflows that need warranty status before authorizing repair.
• Resolving a vague user-supplied model ("my T14") to a concrete machine-type variant.

Workflow

The agent uses a hybrid path: an undocumented JSON resolver gets you from any identifier to the canonical product slug in one HTTP call, then you browse the rendered sub-pages with stealth+proxy to scrape the actual artifacts. Pure-API harvesting of drivers/parts is not available — the public REST API at supportapi.lenovo.com requires a sales-issued ClientID (verified 2026-05-20: docs page returns 200 but every endpoint demands ClientID: header), and the in-browser XHR endpoints (/api/v4/mse/getdocument, /api/v4/mse/getUserguide, etc.) are 404 or deny access from outside the page context.

1. Resolve the identifier → canonical product slug (JSON, no auth)

GET https://pcsupport.lenovo.com/us/en/api/v4/mse/getproducts?productId={query}

{query} accepts:

• Machine type (4 chars, e.g. 21ML, 20VE) — returns Type: "Product.MachineType".
• Serial number (8 chars, e.g. PF2W2GLT) — returns Type: "Product.Serial" plus the parent machine-type chain in Id.
• Marketing name (e.g. ThinkPad+T14+Gen+5) — does NOT work, returns []. Use machine type or serial.

The response is a JSON array; each entry has:

• Id — slash-delimited slug (e.g. LAPTOPS-AND-NETBOOKS/THINKPAD-T-SERIES-LAPTOPS/THINKPAD-T14-GEN-5-TYPE-21ML-21MM/21ML). Lowercase this and append it to https://pcsupport.lenovo.com/us/en/products/ to build the product home URL.
• Name — human-readable label.
• Type — Product.MachineType, Product.SubSeries, or Product.Serial.
• Brand — TPG (ThinkPad-Gov / commercial), IDEA (consumer), etc.

Multiple entries returned ⇒ pick the one matching Type == "Product.MachineType" for a clean machine-type query, or the entry whose Serial field equals the input for a serial query. Empty [] ⇒ unknown identifier; bail with success: false, error_reasoning: "product not found".

This call works without --verified and without --proxies — it's served straight from the API tier and is not gated by Akamai for JSON Accept. ~200ms typical.

2. Open the product home page (browser, stealth+proxy required)

https://pcsupport.lenovo.com/us/en/products/{lowercased Id}

Example: …/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t14-gen-5-type-21ml-21mm/21ml

The HTML pages are Akamai-fronted (_abck, bm_sz, ak_p cookies in every response). A bare Browserbase session typically gets through but stealth is recommended:

sid=$(browse cloud sessions create --keep-alive --verified --proxies | …)
browse open "$URL" --remote --session "$sid"
browse wait timeout 3000 --remote --session "$sid"   # client-side hydration
browse snapshot --remote --session "$sid"

The product home page surfaces the four primary tab links (Drivers & Software, Diagnose & Fix, Guides & Manuals, Warranty & Service) — but you can navigate to each tab's URL directly (paths below).

3. Hardware Maintenance Manual (HMM) — the priority artifact

Navigate to:

…/products/{lowercased Id}/document-userguide/doc_userguide

The HMM PDF link is not at a guessable filename. It's published at https://download.lenovo.com/pccbbs/{folder}_pdf/{combined-model-slug}_hmm_en.pdf where:

• {folder} is mobiles_pdf for laptops/ThinkPad/IdeaPad, thinkcentre_pdf / desktops_pdf for desktops, motherboards_pdf for boards.
• {combined-model-slug} is a multi-model combined slug because Lenovo publishes one HMM per chassis-family. Verified 2026-05-20: T14 Gen 5 (21ML) HMM is at …/mobiles_pdf/t14g5_t16g3_p14sg5_hmm_en.pdf — covering T14 Gen 5 + T16 Gen 3 + P14s Gen 5 in one PDF.

Don't guess the slug — scrape it from the rendered page. After wait timeout 3000, the doc list resolves and the URL is in the page HTML (search download\.lenovo\.com/pccbbs/[^"]+_hmm_en\.pdf after browse get html body). The clickable list shows href="#" placeholders pre-hydration, so don't extract from anchors before the wait.

Example one-liner (after navigating to the doc_userguide page):

browse get html body --remote --session "$sid" \
  | grep -oE 'https?://download\.lenovo\.com/pccbbs/[^"]+_hmm_en\.pdf' \
  | head -1

4. Drivers, BIOS/UEFI, diagnostic tools

…/products/{lowercased Id}/downloads/driver-list

The page hydrates client-side and shows a category list (BIOS/UEFI, Chipset, Audio, Camera, Networking, Storage, …). Each category is collapsed; click the category row to expand and reveal individual driver rows (name, version, OS, severity, "Download" button). The flat XHR endpoint that backs this UI (/api/v4/downloads/drivers) returns {"body":"","message":"deny access"} to outside-page calls — there's no shortcut. Snapshot strategy:

browse open ".../downloads/driver-list" --remote --session "$sid"
browse wait timeout 3000 --remote --session "$sid"
browse snapshot --remote --session "$sid"          # category refs
browse click "@<bios-category-ref>" --remote --session "$sid"
browse wait timeout 2000 --remote --session "$sid"
browse snapshot --remote --session "$sid"          # individual drivers visible

The Download anchors are absolute URLs to download.lenovo.com/pccbbs/{folder}/...exe (Windows installers) or .../...iso for bootable BIOS update images.

Diagnostic tools: same page, look for the "Diagnostic Tools" category (when present) — typically Lenovo Diagnostics — Bootable USB ISO + Lenovo Diagnostics — Windows.

5. Parts (FRU/CRU)

…/products/{lowercased Id}/parts/PARTS_BOM_LOOKUP

Renders a BOM table: part description, FRU number, CRU type (Self / Optional / N — "non-CRU, FRU only"), price (where available). The page is also JS-rendered — wait timeout 3000 then snapshot.

6. Self-Repair Guide (ThinkPad / ThinkCentre / ThinkStation only)

A separate site, not under the product slug:

https://support.lenovo.com/us/en/selfrepair/sr{NNNNNN}-{kebab-product-name}-self-repair-guide

The numeric sr{NNNNNN} ID has no derivation rule — it's not the machine type, not the GUID, not the slug hash. Discover it via search, not guessing: either (a) Browserbase Search (browse cloud search "lenovo {model} self-repair guide") — first hit is reliably the canonical SR URL — or (b) the "Repair & Service" tab on the product home page links into it.

Verified 2026-05-20: T14 Gen 5 → sr500045-thinkpad-t14-gen-5-21ml-21mm-self-repair-guide (covers all four sibling machine types 21ML, 21MM, 21MC, 21MD).

Self-Repair Guides are interactive HTML walkthroughs with embedded videos and step-by-step procedures — substantially friendlier than the HMM PDF for non-technicians.

7. Warranty status

https://pcsupport.lenovo.com/us/en/warrantylookup

(redirects to …/warranty-lookup#/)

The form requires a serial number — machine type alone returns nothing. The lookup is a single text input + Submit button. After submit:

• wait timeout 4000
• The result panel shows: status badge (Active / Expired), warranty type (e.g. Premium Care), start date, end date, country of purchase, model description.

If the request only supplied a machine type (no serial), return warranty: null, warranty_note: "serial required". The pcsupport.lenovo.com warranty lookup is rate-limited if hammered — keep ≤ 1 req/sec sustained.

8. Service bulletins

Service bulletins (a.k.a. "Solutions" / "Tip" articles) live at:

…/products/{lowercased Id}/solutions/documentation

Filter the list by category badge: "Tip" articles include known-issue advisories and bulletin-style notes. There is no separate "service bulletin" feed — Lenovo merges them with how-tos in the Solutions section.

Site-Specific Gotchas

• The published REST API at supportapi.lenovo.com is gated. The docs page (/Documentation/Index.html) advertises Warranty, Catalog, Product, Content, Part, Accessory endpoints — but every call requires a ClientID: header obtained via "your account manager or sales representative." For agent-runtime use, this is unreachable. Don't waste budget probing it.
• mse/getproducts is the unsung hero. Smart resolver — accepts machine type (4-char), serial number (8-char), and full slug; returns the canonical Id slash-path you need to build every other URL. Marketing names ("ThinkPad T14") return empty. The endpoint works without proxy/stealth (no Akamai gate on Accept: application/json).
• Other mse/* endpoints look promising but are 404 or deny access from outside the rendered page context. Verified 2026-05-20: getdocument, getUserguide, getProductsBySerialId, downloads/drivers, contents/list, contents/getContentsByProductId, upgradableComponents/products/{...} all fail. The browser is required to render the JS app before these XHRs are accepted.
• Akamai stealth wall is mild. A --verified --proxies session passes uniformly. A bare session (no flags) also generally passes for pcsupport.lenovo.com page renders, but inconsistently — recommend --verified --proxies for reliability. The download.lenovo.com PDF/EXE host is not Akamai-gated; direct curl works.
• HMM PDFs are combined across sibling models. A single PDF covers all chassis-mates. T14 Gen 5 + T16 Gen 3 + P14s Gen 5 share t14g5_t16g3_p14sg5_hmm_en.pdf. Don't try to derive the slug from the machine type — scrape it from the document-userguide/doc_userguide page after wait timeout 3000.
• document-userguide page anchors are href="#" pre-hydration. The actual PDF URLs land in a JS urlMap object that resolves on the click handler. After waiting 3s, the URLs are in the page HTML (just not in the anchor href — they're in script-tag JSON). Use a regex on browse get html body, not browse snapshot ref enumeration.
• HMM PDFs are large (often 30-100 MB). browse cloud fetch --proxies will return a 502 "response body exceeded the maximum allowed size" — verify availability via HEAD or browser navigation, don't try to download through the proxy fetch.
• Driver-list page is fully client-rendered. The categories list shows after wait timeout 3000; individual drivers only appear after expanding a category (browse click @<category> → wait → snapshot). The XHR endpoint that backs this is gated to in-page calls only.
• Self-Repair Guide IDs (srNNNNNN) are unguessable. No deterministic mapping from machine type to SR ID. Use Browserbase Search as a discovery shortcut — "lenovo {model} self-repair guide" reliably surfaces the canonical URL as result #1.
• Warranty lookup needs the serial. Machine type alone is insufficient. Note this in the output JSON instead of fabricating data.
• mse/getproducts Brand codes: TPG = ThinkPad/Think commercial, IDEA = consumer (IdeaPad/Yoga/Legion), LEN/LCFC/etc. = OEM/legacy. Useful for routing — Self-Repair Guides only exist for TPG.
• Locale: paths under /us/en/ work for any machine type globally; non-US users are served the same artifacts. The X-Country header (referenced in the eSupport WebAPI docs) only matters for the gated REST API. For the public web UI just use /us/en/.
