It is listed as 100% tested and comes with a 45-day seller warranty from StoneTaskin — not an HP factory warranty . ⚡ Core Specifications Item Details HP Spare / FRU (SPS) M35805-601 (also referenced as M35805-xxx family) OEM Board No. 6050A3216701-MB (Quanta platform) Compatible Laptop HP EliteBook 850 G8 — 15.6″ chassis (Model series: 2xxx, 3xxx, 4xxx etc.; confirm via bottom sticker) Processor Intel Core i5-1135G7 (Tiger Lake-U, 10nm, soldered BGA — not socketed) CPU Specs 4 cores / 8 threads · 2.4GHz base · up to 4.2GHz Turbo · 8MB L3 cache · 15W TDP (configurable) Graphics UMA = Intel Iris Xe Graphics (integrated only — no discrete MX450 on this M35805-601 variant) Memory Slots 2× DDR4 SO-DIMM (user-accessible, not soldered) — supports up to 64GB DDR4-3200 Storage M.2 2280 slot — PCIe Gen3 x4 NVMe (SSD transfers from old board) Wireless (typical) Intel Wi-Fi 6 AX201 (2×2) + Bluetooth 5.x combo (M.2 2230 module — may or may not be included; check seller photos) Key I/O (on board) 2× Thunderbolt 4 / USB4 Type-C · 2× USB 3.2 Gen1 Type-A (1 w/ charging) · HDMI 2.0b · Audio combo · Power jack Condition Used / Pulled or Refurbished — 100% tested (per seller claim) Warranty 45 Days — third-party (StoneTaskin), not HP official ⚠️ Critical Compatibility — Read Before You Buy 1) Match by Spare Number, NOT just "850 G8" HP uses different system board spare numbers for different CPU tiers and GPU configurations within the 850 G8 family : Spare Family CPU Graphics Notes M35805-601 i5-1135G7 UMA (Iris Xe) ← This listing M35806-xxx / M35807-xxx / M35808-xxx i7-1165G7 UMA or MX450 discrete Higher trims / dGPU Even if your laptop is an EliteBook 850 G8, an i7 board ≠ i5 board and UMA ≠ MX450 board. They are different spare numbers and not interchangeable. 2) How to confirm your board matches M35805-601 Flip the laptop over → read the bottom sticker (Serial / Product / SPS number), or: Open the bottom cover and look at the white label on the motherboard itself — it should show M35805-001 or M35805-601 (the -601is the Windows spare kit) Alternatively, in Windows: CMD → run wmic baseboard get product,version,serialnumber(prints board info, though HP custom boards may show generic strings) 3) What this board does / doesn't have ✅ Included / On-board ❌ NOT Included (you transfer or buy separately) i5-1135G7 (soldered) RAM SO-DIMMs — your old sticks transfer (2 slots) Intel Iris Xe (UMA) M.2 NVMe SSD — your old SSD transfers All capacitors, VRMs, ports Wi-Fi card — usually transfers (verify if seller includes one) BIOS / Embedded Controller Thermal module (heatsink + fan) — NOT included on most listings; buy/keep yours + fresh thermal paste 🔧 Installation Difficulty: High (Full Strip) Replacing the 850 G8 motherboard means: Bottom cover off → disconnect battery first (critical) Remove: heatsink/fan, SSD, Wi-Fi, all ZIF ribbons (keyboard, touchpad, trackpoint, fingerprint, display cable, antenna coax) Unbolt motherboard caddy Reverse with your SSD/RAM/Wi-Fi transferred + fresh high-quality thermal paste on CPU/GPU die contact points The Thunderbolt controller, power rail, and coax antenna tips are the three things most commonly damaged during DIY swaps on EliteBooks. If you haven't done a full business-ultrabook teardown before, use a pro. 🛡️ Warranty / Seller Note 45 days = seller-level only — covers DOA / no-power / obvious dead-component issues after correct installation Not covered in practice: ripped ZIF ribbons, snapped coax tips, burnt board from reused damaged battery, liquid history, bent pins Pay via platform-protected checkout (AliExpress/eBay/PayPal Goods & Services) — do not bank-transfer for this class of part Upon arrival: photo the board label (M35805-601 + S/N) and inspect port corners / capacitor tops before install ✅ Pre-Purchase Checklist Photo the bottom sticker of your EliteBook 850 G8 (or the white label on the existing motherboard) → confirm you see M35805-001 / M35805-601 Confirm your original fault is truly the main board (no power / liquid-killed / known short) and not just: USB-C PD controller (common — port stops charging but board otherwise alive) Bad battery Broken keyboard ribbon Tell StoneTaskin you need exact M35805-601 and ask for photos of the actual unit before shipment Bottom line: This M35805-601 / 6050A3216701-MB is the correct HP spare-grade board for an EliteBook 850 G8 with i5-1135G7 + UMA (Iris Xe). It's a used/pulled part via a third-party seller — the 45-day window is your only safety net, so verify the spare number match before you commit and use protected payment. If you paste the text from your laptop's bottom sticker, I'll confirm the match definitively.
