X230 Laptop Modification & Xiaomi PD Upgrade
Introducing the X230, a venerable first-generation computing marvel renowned for its exceptional keyboard and utilization of a standard voltage CPU. Notably, this device allows for a screen upgrade to a crisp 1080P resolution.
For those equipped with a Xiaomi PD adapter featuring a Type-C interface, a remarkable charging capability at 65W is at your disposal. Furthermore, this adapter seamlessly powers your laptop, though it may not directly recognize the resistance, ultimately delivering an impressive 95W of power. In light of this, an intriguing opportunity arises to explore an internal modification.
Here is a detailed breakdown of the process:
1. Identify the Power Recognition Mechanism:
When connecting a 65W adapter, ensure that it recognizes a 10K resistance to the ground.
2. Manual Augmentation:
Employ a 10K surface-mount resistor and a high-capacity surface-mount diode to safeguard against potential issues when using the original adapter. Connect this assembly to the insurance front end, with the understanding that a 3A current poses no significant concerns. Notably, the connection is limited to +20V and GND, which are directly linked to the casing. Extensive testing has confirmed the reliability of this setup.
3. Location Selection:
The modification can be situated in one of two locations:
· Option 1: Adjacent to the right-side lock hole, benefitting from secure fastening with hardware components (as demonstrated in this example).
· Option 2: Positioned beneath the power button. While it eliminates interference concerns, it lacks a fixed location, making it slightly less aesthetically pleasing when secured with adhesive.
· Final Product:
Once installed, the modification exhibits remarkable stability, particularly when attached using the hardware components near the lock hole.
4. Visual Outcome:
Post-installation, the modification yields a visually appealing result that seamlessly integrates with the X230's design.
In practical testing, the power identification process for 65W operation appears to perform admirably, with the Xiaomi PD adapter maintaining a comfortable operating temperature. This transformation represents a promising success story for X230 enthusiasts seeking enhanced charging capabilities and power management.
