Frequently asked questions

What does the warranty cover?

Our warranty covers all hardware faults, but please note it doesn’t cover accidental damage or software issues. However, we’re here to help with technical support for those matters!

What is a refurbished device?

A refurbished device is a pre-owned item that has been restored to meet high-quality standards. At Reboot IT, we adhere to strict quality guidelines, ensuring that our refurbished products are not the same as used or secondhand items. We meticulously clean, test, and assess each device, replacing worn parts with high-quality components.

Unlike used items, which lack guarantees and rely solely on the seller's word regarding condition, refurbished devices come with assurance of quality and reliability.

What payment options are available?

We offer a variety of payment options to make your shopping experience as convenient as possible! You can pay using all major credit cards, Apple Pay, Google Pay, Shop Pay, Afterpay, Zip Pay, and PayPal. If you prefer, we also accept bank deposits and even cash for in-store purchases!

Lenovo ThinkPad Mini Dock Series 3 — Single-Cable Desk Expansion

The ThinkPad Mini Dock Series 3 (Type 4337) turns any compatible ThinkPad into a full desktop workstation with one connection — USB 3.0, dual display, Gigabit Ethernet, and audio all live the moment you dock. Backed by a full 12-month warranty from Reboot IT (Melbourne, est. 2001). Note: power adapter not included.

Key Benefits

  • USB 3.0 SuperSpeed: 5Gbps throughput — transfer a 50GB project from an external SSD in under 3 minutes versus 20+ on USB 2.0.
  • Dual Display Support: DVI-D and VGA ports let you run two external monitors simultaneously for expanded screen real estate.
  • One-Click Docking: Single proprietary connector attaches all peripherals at once — no plugging in individual cables each morning.
  • Gigabit Ethernet: Stable wired 1Gbps network — more reliable than Wi-Fi for video calls, VPN, and large file transfers.
  • Always-On USB: One USB port stays powered when the laptop is undocked, keeping devices charged continuously.
  • Compact Footprint: Low-profile housing keeps desk space clear while providing a stable base for your ThinkPad.

Performance in Use

Arrive at your desk, drop your ThinkPad onto the dock, and everything connects — dual monitors, keyboard, mouse, Ethernet, and USB storage, all instantly. Undock at the end of the day and you take only the laptop. No cables pulled individually.

For IT teams standardising hot-desk environments, one Mini Dock Series 3 model covers a wide range of T, L, and W series ThinkPads — simplifying procurement and making every desk interchangeable without per-user cable setups.

The USB 3.0 Always-On port is useful for anyone who leaves a device charging at their desk overnight. The dock stays powered even with no laptop attached, so phones and tablets charge without needing the laptop to be present.

Frequently Asked Questions

Which ThinkPad models are compatible with this dock?

The Mini Dock Series 3 (Type 4337) uses Lenovo's proprietary ThinkPad dock connector. It is compatible with select T, L, and W series ThinkPads. Check Lenovo's official compatibility list using your exact ThinkPad model number before purchasing.

Does it include a power adapter?

No — the power adapter is not included. You will need a compatible Lenovo 90W or 135W power supply (sold separately) to power the dock and charge your laptop through it.

Can I connect two monitors?

Yes. The dock has one DVI-D and one VGA output for dual monitor support. Supported resolution depends on your ThinkPad's GPU and the monitors connected.

Is USB 3.0 backward compatible?

Yes — USB 3.0 is fully backward compatible with USB 2.0 and USB 1.1 devices. They run at their native speed, not USB 3.0 speeds.

How does shipping work?

This item ships free via standard Australia Post delivery to any address in Australia. Orders dispatch within 1 business day from our Melbourne warehouse.

12-Month Warranty & Reboot IT Guarantee

Every dock is covered by a full 12-month warranty on all hardware and ports. Reboot IT has been Melbourne's trusted certified refurbisher since 2001 — every unit is tested before it ships. Your order includes free standard AU delivery.
