For those who can't read simplified Chinese, basically the op of that post created a summary of all the latest hacks you can apply to X41 or X41T thinkpads (need to be registered to see the instruction images).
They include:
1. LED backlighting (no instructions unfortunately, only a reference to some place in China that can do the ccfl to led conversion).
2. Native SATA interface
3. hacked BIOS to avoid 2010 error (& other inconveniences)
4. OVERCLOCKING! Apparently, some with the PM 1.5Ghz CPU are able to overclock to 2.0Ghz with just a single wire soldering just underneath the memory expansion slot without even have to open the system!
5. Adding memory (nothing special here)
6. Hacking a Mac power brick to be used with X41T (saves space).
Hope that helps someone that would like to squeeze a little more life out of these systems
