Lenovo ThinkPad E14 Gen 1 — 14" Laptop (Faulty LAN Port)
The Lenovo ThinkPad E14 Gen 1 runs a 10th Gen quad-core Intel Core i5-10210U with 8GB DDR4 RAM, a 256GB NVMe SSD and a 14-inch Full HD IPS display, running Windows 11 Pro. Please note: the built-in RJ-45 Ethernet (LAN) port on this unit is faulty and does not work — Wi-Fi and all other functions are unaffected, and the laptop is priced accordingly. Backed by a 12-month Reboot IT warranty on all working components.
Key Benefits
-
Faulty LAN Port — Disclosed Up Front: The wired Ethernet port does not function. Wi-Fi works normally, and a USB or USB-C Ethernet adapter restores wired networking for a few dollars if you need it.
-
10th Gen Quad-Core i5: The i5-10210U runs four cores and eight threads with a 4.2GHz boost — a newer generation than most used business laptops at this size.
-
Windows 11 Pro Pre-Installed: Domain join, BitLocker drive encryption, Group Policy and Remote Desktop all included — pre-installed and activated, ready for a managed business environment.
-
Fast 256GB NVMe SSD: PCIe NVMe storage delivers quick boots and instant application launches, with roughly 180–200GB usable after the operating system and applications.
-
14" Full HD IPS Display: A sharp 1920 x 1080 anti-glare panel with wide viewing angles — comfortable for a full day of documents, spreadsheets and video calls.
-
Priced for the Fault: This unit is discounted against a fully working equivalent. If you work over Wi-Fi — as most people now do — the faulty port costs you nothing in practice.
Performance in Use
Set the LAN port aside for a moment and this is a capable machine. The i5-10210U is a Comet Lake quad-core with eight threads and a 4.2GHz boost, a full two generations newer than the 8th Gen chips that dominate the used market. Office applications, video conferencing, browser-heavy work and general business software all run comfortably under Windows 11 Pro, and the NVMe SSD keeps the whole system feeling immediate.
The 8GB of RAM is the practical constraint. It is enough for a focused workload — a browser, Office and a video call — but it will not stretch to heavy multitasking the way a 16GB machine does. For a single-user, task-focused role this is a sensible configuration; for someone who lives with thirty tabs open, look at a 16GB unit instead.
On the fault itself: the RJ-45 Ethernet port is non-functional and will not pass traffic. Wireless networking, USB, display output, audio, the keyboard, trackpad, camera and storage are all unaffected. In practice most users never plug in a cable, and where wired networking is required a USB-A or USB-C Gigabit Ethernet adapter is a cheap and completely reliable substitute. We have disclosed the fault here, in the product title, and it is reflected in the price — the 12-month warranty covers every other component as normal.

Frequently Asked Questions
What exactly is wrong with the LAN port?
The built-in RJ-45 Ethernet port does not pass network traffic. It is a hardware fault on this individual unit. Everything else — Wi-Fi, Bluetooth, USB, display output, audio, keyboard, trackpad, camera and storage — works normally.
Can I still use wired networking?
Yes. A USB-A or USB-C Gigabit Ethernet adapter plugs straight in and works immediately under Windows and Linux. They are inexpensive and completely reliable.
Is the fault covered by the warranty?
No — the LAN fault is disclosed up front and excluded, and the price reflects it. The 12-month warranty covers every other hardware component as normal.
Does Wi-Fi work properly?
Yes. Wireless networking and Bluetooth are fully functional and tested. Only the wired Ethernet port is affected.
Is 8GB of RAM enough?
For focused single-user work — Office, email, browsing and video calls — yes. If you routinely run many applications at once, a 16GB machine will serve you better.
Does it come with Windows activated?
Yes. Windows 11 Pro 64-bit is pre-installed and activated. The laptop arrives ready for you to create a user account and join your network or domain — no additional licence purchase required.
What are the shipping arrangements?
Yes — free standard shipping Australia-wide is included with your purchase.
