The HP EliteBook 840 14 inch G11 Notebook PC, launched in 2024 and sold on shelves through 2025, is the eleventh-generation entry in HP's flagship 14-inch business line and the first EliteBook 840 built on Intel Core Ultra Series 1 ("Meteor Lake") silicon with a dedicated NPU for on-device AI. Wrapped in a machined aluminum shell just 9.04 mm thin at the front edge and weighing roughly 3.1 lb, it pairs a 16:10 WUXGA display, dual Thunderbolt 4 ports, and — unusually for a modern ultraportable — two user-replaceable SODIMM memory slots. Because HP shipped this model in hundreds of factory build codes spanning two very different processor families, your exact configuration is what sets your payout. Many sellers don't realize they can trade in a working business laptop for cash instead of letting it sit in a drawer — Gadget Salvation has been buying pre-owned electronics directly from sellers since 2008, with free insured shipping and payment within about two business days.

Model identification & look-alike models

Confirm it in Windows (easiest method)

  • Hold the Windows key and press R
  • Type msinfo32 and press Enter
  • Read the line labeled System Model
  • It must say HP EliteBook 840 14 inch G11 Notebook PC
  • The line labeled Processor must begin with Intel(R) Core(TM) Ultra 5 or Ultra 7

Check the sticker on the bottom

  • Close the lid and flip the laptop over
  • Find the small printed label near the rubber foot strips
  • Look for Product — a 6–7 character code ending in UT, UA, or AV (example: A6SZ6UT#ABA)
  • Look for Serial — a 10-character code starting with 5CD, 8CG, CND, or similar
  • Either code alone is enough for us to price your unit

Known factory build codes (partial list)

  • Base unit / AV codes: 8M4W2AV, 8M4W3AV
  • Retail & channel SKUs: A6SY4UT, A6SY6UT, A6SY7UT, A6SZ1UT, A6SZ2UT, A6SZ3UT, A6SZ5UT, A6SZ6UT
  • vPro Enterprise SKUs: AK1W9UA, AK1X0UA
  • US units carry the #ABA country suffix
  • Hundreds of additional configure-to-order codes exist — if yours isn't listed, it is still the same machine

⚠ Do not confuse with these models

  • EliteBook 845 G11 — identical 14" chassis, but AMD Ryzen processor. This is the single most common mix-up. If msinfo32 shows "AMD Ryzen," you have the 845, not the 840.
  • EliteBook 840 G10 (2023) — reads Core i5-1335U / i7-1355U / i7-1365U, never "Core Ultra"
  • EliteBook 860 G11 — 16-inch screen with a number pad
  • EliteBook 830 G11 — 13.3-inch screen
  • EliteBook x360 1040 G11 — screen folds all the way back into a tablet
  • EliteBook 8 G1i — the 2025 successor under HP's renamed lineup

  • Intel Core Ultra 7 165H — 16 cores, 22 threads, up to 5.0 GHz, 24MB cache (vPro)
  • H-series units run at roughly double the sustained power of U-series and are worth noticeably more at trade-in

Graphics (GPU) — integrated only

  • U-series builds: Intel Graphics, 4 Xe cores
  • Core Ultra 5 125H builds: Intel Arc Graphics, 7 Xe cores
  • Ultra 5 135H / Ultra 7 155H / 165H builds: Intel Arc Graphics, 8 Xe cores
  • No discrete NVIDIA or AMD graphics chip was ever offered in this model — every 840 G11 uses the processor's built-in graphics
  • Arc-equipped units benefit from dual-channel memory; a single memory stick drops Arc performance sharply

Memory (RAM) — upgradable

  • DDR5-5600 SO-DIMM, two physical slots, not soldered
  • Factory capacities: 8GB, 16GB, 32GB, and 64GB
  • HP's official ceiling is 64GB in dual-channel mode
  • Both slots sit under a lift-off metal cap with a fabric pull tab, reachable after removing five Phillips screws
  • Aftermarket RAM upgrades do not disqualify your unit — tell us the capacity actually installed today

Storage

  • M.2 2280 PCIe Gen4 x4 NVMe SSD
  • Factory capacities: 256GB, 512GB, 1TB, and 2TB (4TB via aftermarket)
  • Only one M.2 slot — there is no second drive bay, and no 2.5-inch bay
  • Common factory drives include the Samsung PM9B1 series

Operating system & security

  • Windows 11 Pro (most common), Windows 11 Home, Windows 11 Pro Education, or FreeDOS
  • Discrete TPM 2.0 chip, HP Sure Start Gen6 self-healing BIOS, HP Wolf Security for Business
  • Optional extras that raise value: fingerprint reader, IR camera for face sign-in, smart card reader, NFC

Display & audio

Display panels

All panels are 14.0-inch IPS in a tall 16:10 aspect ratio — noticeably squarer than the older 16:9 EliteBooks. HP offered six variants: WUXGA (1920 × 1200) at 300 nits / 45% NTSC; WUXGA at 400 nits / 100% sRGB; WUXGA touchscreen at 400 nits; WUXGA at 1,000 nits for outdoor use; WUXGA at 800 nits with HP Sure View 5 integrated privacy screen; and a premium WQXGA (2560 × 1600) 120Hz panel at 500 nits with 100% DCI-P3 coverage. The WQXGA 120Hz and Sure View panels carry the highest trade-in premiums.

Audio, camera & mic

Dual stereo speakers driven by discrete amplifiers and tuned by Poly Studio, paired with a dual-array digital microphone. Above the screen sits a 5MP webcam with a physical privacy shutter; IR sensors for Windows Hello facial recognition were an optional extra, so not every unit has them.

Ports & connectivity

Four USB ports on a 14-inch, sub-10 mm chassis is generous for this class. Note that charging happens over USB-C — there is no round barrel-style power jack on this generation.

Left Side
  • 2× USB-C Thunderbolt 4 / USB4 (40 Gbps, Power Delivery charging, DisplayPort output)
  • 1× USB-A 3.2 Gen 1 (5 Gbps, supports charging your phone)
  • 1× HDMI 2.1
  • 1× Smart card reader (optional — many units do not have it)
Right Side
  • 1× USB-A 3.2 Gen 1 (5 Gbps, sleep-and-charge)
  • 1× 3.5mm headphone/microphone combo jack
  • 1× Nano-lock security slot
  • 1× Nano-SIM tray (optional, only on WWAN-equipped units)

Intel Wi-Fi 6E AX211 Bluetooth 5.3 Optional 4G LTE / 5G WWAN + eSIM No SD or microSD card reader No built-in RJ-45 Ethernet port No barrel power jack — charges via USB-C

Battery, build & more

Battery & charging

A single 3-cell 56 Whr lithium-ion pack, rated for roughly 12 hours of video playback in independent testing. Ships with a compact 65W USB-C adapter. Because this is a USB-C charger, most modern laptop and phone chargers of 65W or higher will run the machine — but including the original HP brick still helps your offer.

Keyboard & touchpad

Spill-resistant full-size keyboard with a dedicated Copilot key and no number pad. The backlight was an optional upgrade, not standard equipment — check whether your keys illuminate before selecting that option in the quote tool. The touchpad is a large glass-surfaced click pad.

Cooling

A single fan paired with two long heat pipes, a heat sink, and a heat spreader, exhausting through a rear vent aimed below the display. Fan profiles are managed in the MyHP app rather than a hardware button.

Build & hinge

Machined aluminum lid and base in HP's matte silver finish, with a lever-style hinge that lifts the rear of the chassis for airflow. Maximum opening angle is a rated 172°, nearly flat.

Weight

≈ 1.42 kg (3.13 lb) starting weight — touchscreen and WWAN-equipped configurations run slightly heavier.

Dimensions

315.5 × 224.3 × 9.04–16.35 mm (12.42" × 8.83" × 0.36"–0.64").

Frequently asked questions

01 How do I confirm my laptop is an HP EliteBook 840 G11?
You don't need to open anything or know anything technical. Turn the laptop on, hold the Windows key and tap R, type msinfo32, and press Enter. A window opens listing your system details. The line called System Model should read "HP EliteBook 840 14 inch G11 Notebook PC," and the line called Processor should begin with "Intel(R) Core(TM) Ultra." If the laptop won't power on, flip it over instead and read the small printed label on the bottom cover — the code next to Product (six or seven characters, usually ending in UT or UA) is all we need. Our HP model number guide walks through both methods with pictures, and our general model finder covers every other device we buy.
02 My laptop looks exactly like this one — how do I know it isn't an 845 G11 or an 840 G10?
This is the most common mistake sellers make with this model, and it matters because the wrong page produces the wrong quote. The EliteBook 845 G11 is physically identical to the 840 G11 — same aluminum shell, same 14-inch screen, same ports, same weight. The only reliable difference is the processor: the 840 uses Intel Core Ultra chips, while the 845 uses AMD Ryzen. Run the msinfo32 check above and read the Processor line. If it says AMD, you have the 845 and should use that model's page instead.

The 840 G10 (2023) is the other frequent mix-up. It looks very similar from the outside, but its processor line reads Core i5-1335U, Core i7-1355U, or Core i7-1365U — the words "Core Ultra" will never appear on a G10. Two more quick checks: if your screen measures 16 inches diagonally you have an 860 G11, and if it measures 13.3 inches you have an 830 G11. If the screen folds all the way back flat against the bottom to become a tablet, you have an EliteBook x360 1040 G11. Still unsure after all that? Send us the serial number through custom quote and we'll identify it for you.
03 Will you still buy it if the screen is cracked, the battery is worn, or someone upgraded the RAM?
Yes. We buy EliteBook 840 G11 units in every condition, from sealed-in-box to visibly damaged. Cracked or flickering displays, swollen or dead batteries, dented lids, sticky or missing keycaps, broken hinges, failed touchpads, and units that will not boot at all all still have real value — just grade them honestly in the condition selector above so your offer matches what arrives. Aftermarket changes are fine too: because this model has two accessible SODIMM slots and a replaceable M.2 drive, plenty of units have been upgraded beyond their factory spec. Report the memory and storage that are physically installed today, not what the original invoice said. One thing worth checking before you quote: if the laptop is still locked to a company BIOS password or an asset-management system, tell us up front, since that affects what we can do with the unit.
04 What raises my EliteBook 840 G11 trade-in value the most?
The processor tier is the biggest single lever. A Core Ultra 7 165H or 155H with Intel Arc graphics is worth substantially more than a Core Ultra 5 125U, because the H-series chips sustain roughly double the power and carry a much stronger integrated GPU. After that, the display panel matters more than most sellers expect: the WQXGA 2560 × 1600 120Hz screen and the HP Sure View 5 privacy panel both command clear premiums over the base 300-nit WUXGA. Then come 32GB or 64GB of RAM, 1TB or 2TB of storage, vPro-capable chips, a factory backlit keyboard, WWAN cellular capability, and a fingerprint reader or IR camera.

Many people don't realize that a used business laptop like this one is worth real cash rather than a spot in a closet. Corporate-class machines such as the EliteBook line hold their resale value far better than consumer laptops, because their metal chassis, replaceable parts, and long driver support keep them useful for years after the original owner moves on. Trading yours in is also the greener option — every EliteBook that gets a second owner is one less machine heading to a landfill. Our blog covers this in more depth in how to sell your used HP laptop online, the best HP EliteBook laptops, and what business laptops the Big 4 consulting firms use.

05 How do I wipe my data before shipping, and how do I get paid?
Copy anything you want to keep to an external drive or cloud storage first, then sign out of your Microsoft account and run Settings → System → Recovery → Reset this PC → Remove everything. You do not need to unscrew the case or pull the M.2 drive — our technicians run certified multi-pass erasure on every drive that comes through our lab, documented in our data erasure protocols.

One extra step specific to business laptops: EliteBooks are frequently enrolled in corporate management systems. If this machine came from an employer, ask your IT department to release it from Microsoft Intune, Windows Autopilot, or any MDM profile, and to clear any BIOS or HP Sure Admin password. A machine still bound to a company tenant will re-enroll itself after a reset, which limits its resale value — so please sort this out before shipping.

Once your laptop reaches our facility and passes functional testing, payment is approved within about two business days. Choose from PayPal, Venmo, Zelle, or CashApp, or ask for a paper check mailed to your address. Your prepaid, insured shipping label is free — see how it works and our shipping instructions for packing tips.
