Ibrahim runs a logistics office in Kaduna with eight staff. A year and a half ago he bought eight brand-new consumer laptops from a shop because the price looked good. By month fourteen, one hinge had cracked, two keyboards had stopped working and a charger had started to smell hot. He called me and said, “Dan, I want laptops that last, even if they are not shiny.” I told him about a laptop that has become my most common recommendation for offices in Abuja, Lagos, Kaduna and Port Harcourt: the HP EliteBook 840 G8.

This is my honest HP EliteBook 840 G8 review for Nigerian buyers. I explain what the laptop is, how it performs for office work, what it costs in naira (as at 2026, prices change), how it copes with power cuts and heat, and where it falls short. I also cover how to inspect a UK-used unit before you pay, what to ask about warranty, which alternatives to consider and who should not buy it. You will also find my score out of ten.

In short: the EliteBook 840 G8 is a tough, upgradeable Windows business laptop with good keyboards, plenty of ports and easy repairs in Nigeria. It is not the thinnest, lightest or longest-lasting laptop, and used units vary a lot, so the way you buy matters as much as what you buy. If you want to check the current unit and price, the HP EliteBook 840 G8 Core i7 16GB 512GB SSD product page has the details.

HP EliteBook 840 G8 review: my verdict and score

I rate the HP EliteBook 840 G8 with a Core i7 processor, 16GB of memory and a 512GB SSD at 8 out of 10 overall. For value for money, if you buy a good UK-used unit from a trusted seller, my score is closer to 9. It is a working laptop, not a fashion item. It does the daily jobs of an office without drama, and it can be repaired and upgraded when something ages.

The scorecard

Why this matters in Nigeria

In Nigeria, a business laptop is judged by how it survives our real conditions: generator surges, dusty offices, hot afternoons, crowded bags and repair costs that come out of your own pocket. The exchange rate also means a new laptop can be out of reach for a small business, which is why used business laptops from the UK and Europe have become the backbone of many Nigerian offices. The EliteBook 840 G8 sits right in that market. Getting the purchase right saves you money for years, and getting it wrong costs you twice.

HP EliteBook 840 G8 specs in plain English

HP released the EliteBook 840 G8 in 2021. It belongs to HP’s business range, which means it is designed for company fleets rather than for shop-window sales. That is why you find so many of them coming out of UK and European offices into the Nigerian used market.

Screen, body and weight

The screen is 14 inches with a full HD resolution (1920 by 1080). That is sharp enough for spreadsheets, documents and video calls. Some units have a special privacy screen that makes the display look dark from the side, which is helpful in a crowded office or an airport lounge. Some have touchscreens. The body is mostly aluminium, and HP tests the range against military-style durability standards. At about 1.36 kg to start with, it is portable, but noticeably heavier than a MacBook Air.

Processor, memory and storage

The G8 uses 11th generation Intel Core processors. The version I recommend most is the Core i7 with 16GB of memory and a 512GB SSD (solid state drive, the fast storage). A Core i5 version is also very capable for most office work. The G8 has two memory slots, so you can upgrade later, and the SSD is a standard type that you can replace. This is a big advantage over many thin laptops where memory is soldered to the board and cannot be changed.

Ports, keyboard and camera

The EliteBook has two Thunderbolt 4 USB-C ports, standard USB-A ports, a full-size HDMI port and a headphone jack, and many units also have a network port. Check the ports on the exact unit in your hand. That means you can plug a projector, a flash drive and a monitor without a dongle. The keyboard is backlit and spill-resistant, and the trackpad is comfortable. The camera is a decent HD one with a privacy shutter on many units, and better cameras appear in some versions. Wi-Fi 6 is supported, and some units have a slot for a 4G or 5G SIM.

Security and Windows 11

HP includes business security features, such as a fingerprint reader on many units, a TPM chip and tools that protect the start-up software of the laptop. The 11th generation processors also meet the requirements for Windows 11, which matters because Windows 10 stopped receiving free updates in October 2025. You can check Microsoft’s list on the Windows 11 specifications page. For any office that handles money or customer data, running a supported version of Windows is not optional.

HP EliteBook 840 G8 price in Nigeria (as at 2026, prices change)

The G8 is now a few years old, so most of the units you will find in Nigeria are UK-used or refurbished, with some nearly new stock from importers. Prices follow the exchange rate, the specification and the condition. Use the ranges below as a rough guide only and ask for current quotes.

Price ranges by specification and condition

The listing in my shop gives the live price and stock for the Core i7, 16GB and 512GB model, so use the product page for the real number. I always remind buyers: the cheapest quote is often a laptop with a tired battery, a missing charger or a hidden lock. A slightly higher price from a seller who tests every unit and gives a written warranty is usually the better deal.

The quirks of UK-used stock

Most G8 units in Nigeria come from UK or European offices, and that brings a few quirks that sellers rarely mention. The first is the keyboard layout. A UK keyboard has a taller Enter key and puts some symbols, such as the @ sign and the quotation mark, in different places from a US keyboard. Most people adjust in a few days, but if you type a lot or write code, ask for a US layout or plan to replace the keyboard. The second is the ex-company history: these laptops sat in busy offices, so cosmetic wear on the keys and palm rest is common, and the battery has often been through hundreds of cycles. The third is the power plug. The UK charger uses a three-pin plug, which fits most Nigerian sockets, but if yours comes with an adaptor, replace it with a proper cable. None of these should stop you from buying, but you should know them before you pay.

Upgrade and extra costs to budget for

• A new battery. Roughly ₦45,000 to ₦90,000, depending on whether you choose a genuine or a good aftermarket part.
• More memory. A 16GB memory stick usually costs around ₦35,000 to ₦80,000. Two slots allow you to grow to 32GB or more.
• A bigger SSD. A 1TB SSD is roughly ₦65,000 to ₦130,000.
• A quality charger. If the original charger is missing, buy a good one, not a cheap copy.
• A surge-protected extension and a bag or sleeve. Small costs that protect a big purchase.

How the EliteBook 840 G8 performs in real Nigerian offices

Specs tell one story. Daily work tells another. Here is how the G8 behaves in the jobs I see most often.

Office work, accounting and admin

With a Core i7 and 16GB, the G8 handles Word, Excel, PowerPoint, Outlook, Google Workspace and Chrome with many tabs comfortably. It starts in seconds from the SSD, not minutes. For an accountant, a school bursar or an office administrator in Kaduna or Enugu, it is more than enough. Because it runs Windows, it also runs the local desktop programs that many Nigerian offices depend on, including many accounting, POS and school programs. This is where it beats a MacBook for many buyers: your existing software just works.

Video calls and remote work

Zoom, Google Meet and Teams work well. The microphones and speakers are good for calls, and the camera is fine for daily meetings, even though it will not match the sharper camera on a newer MacBook. If your job is full of calls, use a headset, both for clarity and to reduce office noise. For more ideas on working from home, see my guide to working from home in Nigeria.

Light development and design

For web development, PHP, Python, database work and light design, a Core i7 with 16GB is workable. Heavy video editing, 3D or large machine learning tasks are not the G8’s job. The screen is not colour-accurate enough for professional design or photography, so creatives should consider other options.

The settings I change on every office laptop

A good laptop can still feel bad if it is set up carelessly. Before I hand a G8 to a client, I do these steps:

1. Update Windows and the drivers, then restart, so that security and stability fixes are in place.
2. Trim the start-up list. In Task Manager, open the Startup tab and disable programs that do not need to open at boot. This alone can turn a slow start into a fast one.
3. Set a sensible power plan. Balanced mode on battery and a slightly lower screen brightness stretch the working hours.
4. Turn on disk encryption (BitLocker on Windows Pro) and save the recovery key safely, so a lost laptop does not mean lost data.
5. Install a backup routine that copies important folders to the cloud and to an external drive.
6. Create a standard user account for daily work, and keep the administrator account for installs and changes.
7. Remove trial software and toolbars that some sellers or previous owners leave behind.

If your existing laptops are already slow, my guide on how to speed up a slow laptop shows the first fixes to try before you spend money.

Using the G8 at a desk with monitors

Because the EliteBook has Thunderbolt 4 USB-C ports and an HDMI port, it works well as a desktop replacement. Many offices connect it to one or two external monitors, a keyboard and a mouse through a docking station or a simple USB-C hub. That gives staff a comfortable workspace when they are in the office and a light laptop when they travel. It also improves posture, because the screen sits at eye level and not on the desk. If you want to set up desks for a whole team, a few good monitors and docks are one of the best investments you can make.

Core i5 or Core i7?

For most office work, the difference between a Core i5 and a Core i7 in this generation is small. Memory and storage matter more than the processor label. If you must choose where to put your money, I would take a Core i5 with 16GB and a 512GB SSD over a Core i7 with 8GB and 256GB. The i7 is worth it if you run heavy spreadsheets, multiple virtual machines, or you keep your laptop for five or more years.

Battery, heat and power cuts: what to expect in Nigeria

Power is where laptops in Nigeria face their toughest test. NEPA takes the light, the generator comes on late, the surge hits the charger, and the laptop has to survive all of it. Here is how the EliteBook 840 G8 copes.

Battery life in real life

HP quotes long battery figures that come from lab tests. In real office use with a healthy battery, I usually see somewhere around 6 to 9 hours for light work such as email, documents and browsing, and less when you have video calls, bright screens and many tabs. The problem is not the design, it is age. Many UK-used units come with batteries that have lost part of their capacity, and some give only two to four hours. A tired battery is the biggest hidden cost on a used laptop, so check it and, if needed, replace it as part of the deal.

How to check battery health in two minutes

1. Click the Start button, type cmd and open the Command Prompt.
2. Type powercfg /batteryreport and press Enter. Windows saves a battery report file and shows you where.
3. Open that file in your browser and compare the Design capacity with the Full charge capacity. If the full charge number is far lower than the design number, the battery has worn down.
4. You can also press F2 when you switch the laptop on to open HP’s built-in diagnostics, which include a battery test.

Charging with generators and NEPA

The EliteBook charges through a USB-C charger, usually 65W. Use the original one or a quality certified one. Cheap copies sold in some markets can overheat and damage the charging circuit. Plug into a surge-protected extension, and never connect to a socket that also runs a fridge or air conditioner. If your area has heavy voltage swings, a small UPS or an inverter setup for the office keeps laptops safe and gives you time to save your work when the power drops. I explain how this fits into a bigger office plan in my IT maintenance plan for offices.

Heat, fan noise and dust

Under heavy load, the 11th generation Core i7 can get warm, and the fan will spin up. That is normal. What is not normal is a laptop that is hot and loud during simple tasks. On a used unit, that can mean clogged fans or dried thermal paste. Dust is a real issue in Kano, Jos, Abuja and any city in Harmattan season. A good technician can clean the fans and change the thermal paste in an hour or so. If you are in Abuja, my laptop repair service covers this. As a routine, clean the fans every six to twelve months, keep the laptop on a hard surface and never block the air vents.

Build quality and repairs: why the EliteBook lasts in Nigeria

When a client asks me why I recommend EliteBooks and ThinkPads, my answer is simple: they are built to be used hard and fixed easily.

Made for offices, not for display

Business laptops have stronger hinges, better keyboards and sturdier cases than the cheap consumer models. The G8 has a spill-resistant keyboard, an aluminium chassis and hinges that handle thousands of open and close cycles. When Ibrahim’s staff in Kaduna dropped their old laptops, cracks appeared. The EliteBook survives the same bumps far better, though it is not indestructible, and I still recommend a padded sleeve.

Parts and repairs are easy to find

The 840 line has been sold for many years, so batteries, keyboards, screens, chargers and other parts are widely available in Nigeria. Markets such as Computer Village in Ikeja in Lagos and Banex Plaza in Abuja stock many parts, and lots of technicians know the machine. The warning is to avoid very cheap parts that are poor quality. Ask for a warranty on any part or repair, and never let a technician replace parts without telling you. A laptop that is easy to repair keeps its value.

An upgrade path that gives you extra years

Memory and storage can both be upgraded. If a 16GB laptop feels tight in two years, you can add a bigger memory stick. If the 512GB SSD fills up, you can replace it with a 1TB one. A new battery can bring the laptop back to a day of use. With these upgrades, a well-chosen G8 can serve four to five years or longer, and that is why I say the lifetime cost of an EliteBook is lower than the price tag suggests.

A simple care routine that adds years

• Clean the fans and vents every six to twelve months, or sooner in dusty seasons.
• Keep liquids away, even though the keyboard is spill-resistant. That feature buys you time, not immunity.
• Carry it in a padded sleeve and never press hard on the closed lid in a crowded bag.
• Do not leave it charging under a pillow or on a bed. Heat is the enemy of batteries.
• Shut down or restart regularly. A laptop that runs for weeks without a restart often becomes sluggish.

HP EliteBook 840 G8 pros and cons, and who should buy it

What I like

• Tough build. It handles daily travel, bag knocks and long office hours.
• Great keyboard. Comfortable for accountants, writers and admin staff who type all day.
• Plenty of ports. Fewer dongles, and it works with projectors and monitors directly.
• Upgradeable and repairable. Memory, storage and battery can be changed.
• Windows compatibility. It runs local accounting, POS and school programs.
• Value. A good UK-used unit costs much less than an equal new laptop.
• Business security features. Fingerprint readers, a TPM chip and start-up protection.

What I do not like

• Battery life on used units. Often shorter than you expect until you replace the battery.
• Weight. Heavier and thicker than the newest thin laptops.
• Screen. Fine for work, but not bright or colour-rich for creative use.
• Fan noise. It can get loud under heavy tasks.
• Uneven used stock. Two units with the same label can differ in battery, screen and body condition.
• Possible locks. Some ex-corporate units are locked by a BIOS password or a company management profile.

Who should buy it

• Small business owners equipping staff, such as logistics offices, clinics, schools and shops.
• Accountants, bank staff, administrators and civil servants who live in Excel, Word and email.
• NGO and church office teams who need reliable Windows laptops at a fair price.
• Students and graduates who need Windows software and want a laptop that lasts.
• Consultants on a budget who want a professional look and dependable performance.

Who should not buy it

• Designers, photographers and video editors who need a bright, colour-accurate screen and more graphics power.
• People who want the lightest possible laptop with all-day battery life.
• Buyers who cannot verify a used seller or who want a full brand-new manufacturer warranty at any price.
• Gamers and heavy 3D users.

How to inspect a UK-used EliteBook 840 G8 before you pay

The difference between a great deal and a nightmare is usually the inspection. I do this for my clients, and I suggest you bring a friend who knows computers, or ask me to help. Allow at least thirty minutes and do not let the seller rush you.

1. Match the specs to the quote. Open Settings, then System, then About. Confirm the processor, memory and Windows edition.
2. Check the serial number and warranty status on the manufacturer’s site, such as HP Support. Compare the serial with the sticker under the laptop.
3. Run the battery report with the powercfg command I showed above and read the health numbers.
4. Look at the screen with a white and a black background. Look for dead pixels, patches, lines and pressure marks. Check the brightness at full and at low.
5. Test the keyboard, backlight and trackpad. Type across every key. Click the trackpad buttons. Test the fingerprint reader if there is one.
6. Try every port. USB-A, USB-C, HDMI, network port, headphone jack and the SIM slot if the unit has one.
7. Check the SSD health. A free tool such as CrystalDiskInfo shows the drive status and how much life it has used.
8. Look for locks. Press the key that opens the BIOS setup at start-up and check that there is no password. During Windows setup, if it says the device is managed by an organisation or asks for a company account, walk away.
9. Check Windows activation. In Settings, Activation, it should show as active.
10. Do a heat and noise test. Play a video or run a heavy task for ten minutes. Listen for a loud fan and feel the temperature.
11. Test camera, microphone, speakers, Wi-Fi and Bluetooth. Make a short video call from your phone hotspot.
12. Inspect the body. Look for cracked corners and hinge covers, wobbly hinges and stripped screws, which suggest a previous repair.
13. Get everything in writing. A receipt with the seller’s name, the laptop’s serial number, the specification and the warranty terms. If they refuse, walk away.

Warranty, after-sales and support in Nigeria

The laptop is only half of your purchase. The other half is what happens on the day something goes wrong. With used business laptops, warranty terms differ widely from seller to seller, so this section deserves your full attention.

Manufacturer warranty and seller warranty are not the same

An EliteBook 840 G8 came out in 2021, so any original manufacturer warranty on a used unit has probably ended. Even where the serial number still shows some coverage, the repair may need to happen outside Nigeria. That means the seller’s own warranty is what protects you. Treat it as the most important part of the deal. Ask who stands behind it, where the repair happens and how fast they respond.

What a good seller warranty should cover

• A clear period, counted from the day you collect the laptop, and in writing.
• A short replacement window for a dead-on-arrival unit, so a laptop that fails in the first days is swapped, not argued about.
• Cover for the motherboard, screen, SSD, keyboard and charger. Batteries are often covered for a shorter time or excluded, so ask.
• Who pays for parts and labour, and how long a repair should take.
• A named place where you can bring the laptop, with a phone number that works.

The warranty terms for the unit on my shop are on its product page. Please read them before you pay, and if any detail is unclear, message me on WhatsApp and I will confirm it in writing.

What to do if something fails

If the laptop fails during the warranty, report it right away and keep your receipt. Do not let a random technician open it, because that can void your cover. Back up your files regularly so that a repair does not turn into data loss. I cover the full method in my article on data backup for small business. If you buy for a whole office, a simple support plan with a named technician saves days of lost work.

Alternatives to the HP EliteBook 840 G8

The EliteBook is not the only sensible choice. If it is out of stock, or if your needs differ, look at these. The prices are rough guides as at 2026, prices change, and they depend on condition and specification.

EliteBook 840 G8 versus MacBook Air M2

This is the comparison I am asked about most, so here it is in one table. I cover the MacBook fully in my MacBook Air M2 review.

My rule of thumb: if your software needs Windows, or you buy for several staff on a fixed budget, take the EliteBook. If you travel a lot and your work is browser-based or creative, look hard at the MacBook. If you are buying for a whole team, my business laptop buying guide explains how to choose specifications for each type of staff member.

Where to buy and my final verdict on the EliteBook 840 G8

You can see the current price, stock and warranty terms for the Core i7, 16GB and 512GB SSD model on the HP EliteBook 840 G8 product page. To compare other laptops, phones and devices, browse my shop. Ask every question before you pay.

Red flags when buying a used laptop in Nigeria

Most sellers are honest, but a few habits should make you slow down. Be careful if the price is far below every other quote, because there is usually a reason. Be careful if the seller shows photos that are not of the exact laptop you will receive, or refuses to let you test it. Walk away if there is no receipt, if the seller pushes you with “many people are waiting for it”, or if you are asked to send the full payment to a personal account before you have seen the laptop. Online sellers on Instagram and WhatsApp can be reliable, but verify them: look at real reviews, ask for a video call showing the unit, and where possible pay on collection after you inspect. A good seller does not fear your questions.

Which configuration should you choose?

• Accountant, bursar or admin officer: Core i5, 16GB, 512GB SSD is the sweet spot for spreadsheets and email.
• Front desk or reception: Core i5, 8GB, 256GB is enough, and a good place to save money.
• Developer or IT staff: Core i7 with 16GB now, and a second memory stick added later for 32GB.
• Manager or executive who travels: Core i7 with a fresh battery, and if possible a unit with the privacy screen option.
• Business owner who wants one laptop for five years: Core i7, 16GB, 512GB, then budget for a battery replacement in year three.

Buying for a whole team

If you are equipping five or more staff, treat it as a small project, not a shopping trip:

• Standardise. Buy the same model and specification for staff who do the same job. One charger type, one set of parts and one setup image save time.
• Buy a spare or two. Keep a spare laptop and a few spare chargers so that a failure does not stop work.
• Plan the setup. Install Windows updates, security software, backup and your business programs before handing laptops out.
• Tag and record. Put an asset tag on each laptop and keep a list of serial numbers, staff names and purchase dates.
• Budget for extras. Chargers, sleeves, batteries and surge protectors make up part of the true cost.

What happened in Kaduna. Six months after Ibrahim switched his eight-person logistics office to tested EliteBooks, he told me the change he liked most was not speed but peace. Staff stopped queueing for the one working laptop, and the only problem in half a year was a worn battery on one unit, replaced within a day. He said the total cost, with two new batteries and extra memory for the finance staff, was still lower than what he had spent on the first batch of cheap laptops. Lesson: a laptop that is tough and easy to repair costs less over time than a cheap one that keeps failing.

My final verdict: 8 out of 10. The HP EliteBook 840 G8 is a sensible, long-lasting Windows laptop for offices, professionals and students who value reliability and repairability over looks. Buy it from a seller who tests every unit and gives a written warranty, check the battery and locks, and budget for a battery replacement if needed. Skip it if you need the lightest laptop, the longest battery or a colour-accurate screen.

Key takeaways

• My verdict is 8 out of 10 for the HP EliteBook 840 G8 with a Core i7, 16GB and a 512GB SSD, and about 9 for value when bought used from a trusted seller.
• Strengths: tough build, comfortable keyboard, plenty of ports, upgradeable memory and storage, Windows software compatibility and easy repairs in Nigeria.
• Weak points: heavier than thin laptops, ordinary screen, fan noise under load and batteries that are often worn on used units.
• As at 2026, prices change: expect roughly ₦550,000 to ₦850,000 for a UK-used Core i7 unit with 16GB and 512GB, and less for Core i5 versions.
• Run the powercfg battery report and check for BIOS passwords or company management locks before you pay.
• Budget for a battery (about ₦45,000 to ₦90,000) and possible memory or SSD upgrades.
• The seller’s written warranty matters more than any old manufacturer warranty on a used unit.
• Choose a MacBook Air M2 instead if you travel a lot, do creative work and your software runs on macOS.
