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).
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
x41 overclocking reference x41t, just a fly line on the motherboard, the FSB from 100 to pull 133. 1.33 times the frequency corresponding increase
x41-board memory can generally adapt to the needs of overclocking, CPU is not the same situation:
1.5 The basic frequency can be super-success to 2.0G, 1.6 GHz of only twelve cases currently jars success overclocking to 2.1G
Specific overclocking methods:
Remove the memory cover, fly lines are as follows: From the C676 flew R662
Note that in the fly line with insulation tape

Edit: Perhaps another bios is needed? What bios was used?
I fail registering the chinese site and cannot see their pics...they (due to googletrans) also connect to other resistors!
Someone capable to register and/or chinese?
Thx for any help!
Connected to R674 systems hangs: two poss. 1. my cpu cannot go 2.13Ghz 2. it´s wrong!
they are writing a lot on the chinese forum, maybe there needs to be more!
One of the posts did say just to "spread" the soldering of C676 to the nearby ground plate, but then the author also said it didn't work for him possibly because of his CPU's limitation.
I doubt my Dothan running the 1.6Ghz @0.95V shall be unable to run firstname.lastname@example.orgV, but i have additional 1gb of 4200Mhz Ram.
@stormende: Please tell us about your results + what kind of 2gb Ram you have if it works. Keep in mind that in my case the connection between R674 and the point seemed to be the relevant one. Thx
I have just manage to overclock my pm 758 @2GHz
Got x41 non tablet, just brazed those two points like in a picture above and it worked.
here is my validation:
Watching youtube video @720p warmed cpu to 65 degrees celsius.
I am having a normal PM725, whereas you have the Low Voltage Pentium M you were paying for. weird stuff ey? maybe thats the reason why it´s not working for me...I should have a PM778!!!
Did someone know of that? My X41t has a replacement Mobo w/o S/N and a wrong CPU. I am confused!
@Klimu can you please post your bios version? And did u make a shot of the mod?
many thanks anyway
I didn't took any photos because the mod looks just like on that screen above in loyukfai post.
I have used one naked thin wire from a headphones cable.
Google told me that there ware TP x41 with a pm 725:

Do you have links to images for the page you note?
On my X41 Tablet I'm considering the change to the native SATA interface.
The CCFL is starting to dim and I would be pretty happy if I could figure out how to switch to a LED backlight system.
Overclocking would be useful, except I'm concerned the extra heat would shorten the life of the CPU??
Do you know a source of the hacked BIOS?
Which Mac power adapter are they using that is smaller than the current one?
Changing the cable end seems like a pretty simple thing to do.
Thanks and good health, Weogo Reed
I hoped it would be stable and in that case I would have installed a switch from T60/T61 that would enable or disable overclocking (for example, when on battery, let it be undervolted and lower clocks, when need more oomph, just flick the switch and go! )
Also tried it on one X41 Tablet (1.5 GHz) motherboard but that did not work, booted at its original 1.5 GHz speed.
So far it seems to work only on non-tablets?
X32s:PM 758 LV CPU mod,2GB,64GB microSATA SSD,COM mod,IPS
@Thrakath I've used different sticks Samsung, Adata and Kingston, all of them work the same but I'm a little confused because CPU-Z reports the speed as 99.8 GHz Dual, only one stick displays data and Everest does the same. Doesn't you need to populate both banks to enable the dual channel? If so, how come Win 7 and Everest report the 2.5 Gb but you can't use the extra 512?
Kingston PC2-5300 (333 MHZ)
Win 7 Ranks it as 4.1 which is so far the highest score followed by the 60 Gb Hitachi HD with a decent 3.6
I haven't had time to do the OC mod, I want to do the Sata mod first.
Will keep you posted, gents.
I did a SATA mod on my X41 and using Toshiba 80GB 5400rpm 8MB cache 1.8" SATA drive gave W7 hard drive WEI 5.1. Not bad!stormende wrote: I haven't had time to do the OC mod, I want to do the Sata mod first.

Update: It's immensely difficult getting the solder to stick to the second point! I tried about 3 times and failed. I dont want to try more for i'm afraid of damaging the motherboard.. But i've also noted something. C676 appears to be ground, and the pad inside of the R662 is providing 1.1 Volts when the computer is powered.. effectively causing a short. Is that supposed to happen?
