The HP EliteBook 840 G3 motherboard is now available at Mascom International for KSh 13,500, a brand new replacement system board carrying a soldered 6th generation Intel Core i7-6600U processor, Intel HD Graphics 520, and two DDR4 memory slots. This is the authentic HP mainboard (base part 6050A2822301-MB, HP spares 826808-601 and 918315-601) made to exact factory dimensions for the 14-inch EliteBook 840 G3 and the 15.6-inch EliteBook 850 G3. Mascom International stocks the HP EliteBook 840 G3 motherboard at Old Mutual Building, First Floor Room 4, Kimathi Street, Nairobi CBD, bench-checked and prepared to bring a laptop that no longer powers on back to daily work.
This board is made for IT technicians, computer repair shops, corporate IT departments, schools, and SACCOs across Kenya still running HP EliteBook 840 G3 fleets. The 840 G3 became one of the most widely imported corporate laptops in Kenya, filling offices in Nairobi, Mombasa, and Kisumu from 2016 onward. When one stops powering on after a Kenya Power surge, a spilt cup of tea, or a failed voltage regulator, the system board is usually the part that died, and a dead board normally means a scrapped machine. Replacing the HP EliteBook 840 G3 motherboard restores the whole unit at a fraction of a replacement laptop's price.
Unlike other electronics retailers in Kenya that only sell complete laptops, Mascom International keeps bench-checked spare boards for the machines businesses already own. Every HP EliteBook 840 G3 motherboard is checked for power-on, display output, and port function before it leaves our counter. Repair technicians across Kenya tell us a working board saves clients KSh 20,000 or more against buying another business laptop. Pay by M-Pesa and collect over the counter, bring your laptop to our Nairobi CBD service desk for installation, or order the HP EliteBook 840 G3 motherboard for pay-on-arrival delivery to any of Kenya's 47 counties.
Common Questions About the HP EliteBook 840 G3 motherboard
Will this motherboard fit my HP EliteBook 840 G3?
Yes. This is the correct system board for the HP EliteBook 840 G3, matching HP's exact dimensions, connector positions, and mounting points (base part 6050A2822301-MB, HP spares 826808-601 and 918315-601). Your existing RAM, M.2 SSD, Wi-Fi card, keyboard, and screen connect straight back to it. Confirm your unit is a G3 and not a G4 or G5, since those use different boards. If you are unsure, our Nairobi CBD technicians identify the correct board from your laptop's service tag.
Which processor is on this board, and can I move up to a faster chip later?
The board carries an Intel Core i7-6600U (2 cores, 4 threads) soldered permanently in place, paired with Intel HD Graphics 520. Because the chip is soldered, it cannot be removed or swapped for a different processor later; the CPU and board are one unit. The i7-6600U runs at 2.6GHz base and 3.4GHz turbo, enough for Office, browsers, accounting software, and video calls. Tell us which chip your original carried so we match the build exactly.
Does this same board also fit the HP EliteBook 850 G3?
Yes. HP used the same system board across the 14-inch EliteBook 840 G3 and the 15.6-inch EliteBook 850 G3, so this part fits both chassis. The mounting holes, ports, and connectors are identical between the two sizes. If your 850 G3 stopped powering on because of a board fault, this replacement brings it back exactly as it would an 840 G3. Bring the laptop to our Kimathi Street service desk and we confirm the match before any payment or installation.
My 840 G3 died after a power blackout, will a new board fix it?
Usually, yes. Kenya Power surges, sudden blackouts, and liquid spills kill the system board while leaving the screen, RAM, SSD, and keyboard intact. Fitting a checked board brings the laptop back with all your storage and data still on the original SSD. First, though, confirm the board is the fault and not just the charger or battery. Our Nairobi CBD technicians run a diagnosis so you replace the board only when it is truly the dead part.
Will my Windows, files, and BitLocker still work after the swap?
Your data stays safe because it lives on the SSD, not the motherboard, so the SSD moves across untouched. Windows itself boots normally, though a digital licence tied to the old board may ask for reactivation, since the licence reads the new board's hardware ID. The TPM chip sits on the new board too, so BitLocker-encrypted drives need your recovery key ready before the swap. Back up first. Our technicians handle reactivation and encryption steps during fitting.
Can Mascom install the board, or can I fit it myself?
Both work. Bring your HP EliteBook 840 G3 to our service desk at Old Mutual Building, First Floor Room 4, Kimathi Street, Nairobi CBD, and our technicians transfer your RAM, SSD, Wi-Fi card, and heatsink onto the new board, then test the finished laptop before you pay. Board fitting needs full disassembly, fresh thermal paste, and careful handling, so bench work protects your machine. If you prefer to fit it yourself, we supply the checked board and guidance over WhatsApp.
Is buying a board cheaper than replacing the whole laptop?
Yes, by a wide margin. A working replacement board at KSh 13,500 revives a machine that would otherwise cost KSh 22,000 to KSh 40,000 to replace with a comparable used business laptop. For IT departments running several 840 G3 units, repairing at board level keeps a whole fleet alive at a small share of full-unit pricing. The maths favours repair whenever the screen, chassis, and storage remain healthy. Repair technicians across Kenya tell us this single part is the cheapest route back to a running machine.
Is this an authentic HP board or a generic copy?
This is an authentic HP system board, not a generic "universal fit" copy. HP boards keep the original BIOS and UEFI firmware, HP Sure Start, and the onboard TPM chip intact, which means clean booting with no firmware lockouts or security-chip errors. Generic copies often cause boot failures, security mismatches, and missing driver support. Every board Mascom International sells is bench-checked for power and display output first. You can inspect the part in person at our Kimathi Street counter before buying.
Technical Specifications
Processor and Graphics Configuration
- Intel Core i7-6600U (6th generation Skylake) soldered on-board, so processor and board ship as one checked unit
- Two physical cores and four threads handle Office, accounting packages, browsers, and Zoom calls without stutter
- Base clock of 2.6GHz rises to 3.4GHz turbo, giving quick response on everyday business tasks
- 15W low-power design keeps the board cool inside the thin 840 G3 chassis and helps battery runtime
- Intel HD Graphics 520 sits on the board, driving the internal screen and external monitors
- vPro support lets IT departments manage and secure the machine remotely across an office network
- 4MB Intel cache speeds up repeated work such as spreadsheet recalculation and large document loading
Memory and Storage Interfaces
- Two DDR4 SODIMM slots (2133/2400MHz) accept up to 32GB total, so existing memory transfers straight over
- Dual-channel support pairs two sticks for wider memory bandwidth during heavier multitasking
- One M.2 2280 slot takes a SATA or PCIe NVMe SSD for fast boot and file access
- A 2.5-inch SATA bay lets you keep or add a second drive for extra storage
- Your current SSD carries all data and Windows across to the new board untouched
- Memory and drives are not soldered, so both stay user-serviceable after the board swap
Model Compatibility and Part Numbers
- Fits the 14-inch HP EliteBook 840 G3 and the 15.6-inch HP EliteBook 850 G3 on one shared board
- Recognised numbers include base 6050A2822301-MB with HP spares 826808-601, 918315-601, and 903743-001
- Does not fit the 840 G1, G2, G4, or the G5, which use different boards, so match the generation exactly
- Original connector placement means the screen cable, keyboard ribbon, and battery plug reconnect without adapters
- Mounting-screw positions align with the 840 G3 tray, so no drilling or modification is needed
- Confirm your model from the service tag on the laptop base before ordering to avoid a mismatch
Ports, Docking, and Wireless Support
- One USB-C 3.1 Gen 1 port (5Gbps) carries data and display output, though this generation carries no Thunderbolt
- Two USB-A 3.0 ports restore full peripheral connectivity for mice, drives, and printers after the swap

- Ships in anti-static packaging that protects the circuitry from handling damage during countrywide delivery
- Board fitting needs full disassembly and fresh thermal paste, best handled at our Nairobi CBD service desk
- Our technicians transfer memory, SSD, Wi-Fi card, and heatsink, then test the whole laptop before you pay
- Correct installation protects the new board; damage from DIY fitting errors falls outside warranty cover
