My T430 Upgrades

A guide to modernizing a classic Thinkpad.

Introduction

The ThinkPad T430 is an amazing laptop known for its durability, upgradability, and compatibility with Linux. In this article, I'll discuss the upgrades I have done to bring it into the modern era.

USB-C Charging Port

I wanted an easier way to charge my laptop, so now I only have to carry one charger for all my devices. This mod is surprisingly straightforward.

Required Components:

Power Signaling

Based on the table from the ThinkWiki, we need to choose a resistor that signals the correct power rating to the laptop. For the 65W T430, this is 10kΩ.

Power RatingResistance
65 W10 kΩ
90 WNot Connected
135 W0 Ω
170 W1.5 kΩ

Wiring & Assembly

The wiring is simple: power to power, ground to ground, and the signal pin connected to ground through the 10kΩ resistor. I used a 3D-printed case which fits the PCB perfectly.

The final result is clean and functional. One potential issue is the length of the PCB interfering with the fan; I solved this by carefully filing down a corner of the board.

Engraved Lid

A permanent and personal alternative to stickers. Using a laser cutter, you can engrave a high-detail design onto the lid. Always test your laser's power settings on a similar surface (e.g. other thinkpad) before engraving your laptop.

Backlit Japanese Keyboard

A simple but effective upgrade for both aesthetics and late-night functionality. I found this US-JP layout keyboard with backlighting on eBay.

Slice Battery

For incredible battery life, the slice battery is the ultimate upgrade. My total capacity is now ~125Wh, giving me 14-16 hours of my typical workflow.
