HP ProBook 4 G1iR 16" — Core 5 120U Business Laptop with RJ-45 and Windows 11 Pro
Intel Core 5 120U16 GB DDR5512 GB SSD16" WUXGA
The HP ProBook 4 G1iR 16 inch Notebook PC, Wolf Pro Security Edition (DW6C1AT) is a 16-inch business laptop with an Intel Core 5 120U processor, Windows 11 Pro and HP Wolf Pro Security, built for offices that want a large-screen work laptop with a proper Ethernet port.
This configuration has 16 GB of DDR5-5600 memory in one SODIMM, a 512 GB PCIe NVMe SSD, a 16-inch WUXGA (1920 x 1200) IPS anti-glare display, Intel Wi-Fi 6E with Bluetooth 5.3, gigabit RJ-45, a 1080p camera and a 56 Wh battery in a Pike Silver chassis weighing from 1.74 kg.
What's in the Box
- HP ProBook 4 G1iR 16 notebook (DW6C1AT) with Windows 11 Pro preinstalled
- HP 65 W USB-C power adapter with power cord
- HP Wolf Pro Security Edition licence (1 year)
What It Means in Practice
- Ten cores and twelve threads up to 5.0 GHz keep Office, Teams, browsers and ERP or accounting clients responsive through a full working day.
- The built-in RJ-45 port plugs straight into the office network — no dongle or dock needed for a stable wired connection.
- The 16:10 WUXGA screen shows more rows than a Full HD panel, and the backlit, spill-resistant keyboard includes a numeric keypad for data entry.
- Two USB-C 20Gbps ports support USB Power Delivery and DisplayPort 1.4, so one USB-C dock or monitor can charge the laptop and carry video; HDMI 2.1 adds another screen directly.
- One 16 GB SODIMM leaves the second slot free — adding a matching module gives 32 GB in dual-channel.
What Will Not Work
- This is not a Copilot+ or NPU-equipped AI PC — HP lists no dedicated NPU for the Core 5 120U, so NPU-based on-device AI features are not supported.
- The display is not a touchscreen; with 62.5% sRGB it is meant for office work rather than colour-critical editing.
- There is no Thunderbolt — the USB-C ports are listed at 20Gbps with DisplayPort 1.4.
- The battery is internal and not user-replaceable; battery service goes through warranty.

Frequently Asked Questions
Can it drive two external monitors?
HP lists HDMI 2.1 plus DisplayPort 1.4 on both USB-C ports, so external screens can run alongside the built-in display. Send us your monitor models and we will confirm the best cabling or dock.
Which keyboard layout is supplied?
It has a QWERTY keyboard. If your team needs Greek characters printed on the keys, ask us before ordering.
How is it different from the ProBook 4 G2i 16?
The G2i moves to Core Ultra processors and Wi-Fi 7 but drops the RJ-45 port. The G1iR keeps built-in wired Ethernet, which many offices still rely on.
Singular Expert Insight · Buyer's Guide
The ProBook 4 G1iR 16 is the practical pick for offices that still work on cable: a built-in RJ-45 port, Windows 11 Pro, a big 16:10 screen and a numeric keypad, without paying for AI hardware you may not use. For a one-cable desk setup, pair it with a USB-C dock from our
docking station range.
✓ Buy it if you want a 16-inch Windows 11 Pro work laptop with built-in Ethernet and a numeric keypad for office and accounting work.
✕ Skip it if you want Copilot+ AI features, Wi-Fi 7, a touchscreen or a colour-accurate display.
→ Also consider the ProBook 4 G2i 16 with Core Ultra 5 and Wi-Fi 7 if you do not need a built-in RJ-45 port.
