HP Motherboard L21622-601 – Genuine Replacement Board for HP EliteBook 840r G4
This is a genuine, tested HP laptop motherboard, part number L21622-601, built with an onboard Intel Core i7-8550U processor. It is sourced as a working replacement for the HP EliteBook 840r G4, the reinforced/ruggedized variant of the EliteBook 840 G4 business line. Every board is pulled from a working donor unit, cleaned, and bench-tested for power-on, POST, and I/O function before it is listed for sale.
Key Features & Benefits
- Genuine HP part number L21622-601, matching HP’s own service part listing

- Bench-tested for boot, display output, USB, and charging before dispatch
- Direct drop-in fit for the HP EliteBook 840r G4 chassis
- No BIOS reprogramming or firmware transfer required in most cases

Compatibility & Fitment
Compatible exclusively with the HP EliteBook 840r G4. Before ordering, check the part number printed on your existing motherboard (usually near the RAM slots or CPU socket) against L21622-601 — HP reused chassis across several sub-revisions of the 840 G4 line with different board part numbers. If you’re not sure, send us a photo of your board or your laptop’s full model/serial number and we’ll confirm fitment before you buy.
Performance Overview
The Core i7-8550U is a 4-core/8-thread ultra-low-power processor that comfortably handles office productivity, multiple browser tabs, video calls, and light multitasking. It’s a strong choice for restoring a business laptop to daily-driver condition without the display, keyboard, or battery replacement cost of a whole new machine.
Common Issues This Board Resolves
- Laptop does not power on or shows no LED activity at all
- No display output even with an external monitor connected
- Board damaged by a liquid spill or power surge
- Charging circuit failure — laptop won’t charge on AC power
Why Replace Instead of Buying New?
If your EliteBook 840r G4’s screen, keyboard, and battery are still in good condition, a motherboard swap is a fraction of the cost of a replacement laptop, and keeps a familiar, already-configured machine in service.
