To disassebmle libretto u100, use manual posted by some other user here:
http://www.mediafire.com/?1kgshjbsczz

First of all, the thing I loved most about that manual - is that all connectors have names and numbers!!! So, just read the manual carefully and you will find the connector you need by inspecting the computer. Note: because of that I will not talk about how to remove every single connector - that will just be repeating the manual. I will only mention those that were problematic or somehow special.
Another very important thing - this laptop is very small and has lots of small screws, which are not all the same. You must keep track of them so that it reassembles correctly. I did not, because I was too excited to gut my little friend, whom I love now down to his kidneys. But, again the manual comes to the rescue: they label every kind of screw, and the label embeds the length and color and flatness of the head. So, if you did not keep track of screws, but still have all of them - just read page 4-7 of the manual, and follow instructions for every step of disassembly.

By the way, this is one of the best manuals I’ve read, and I’ve read some manuals!

Step1.jpg
just took off the keyboard. Here all exposed wires need to be unplugged in order to remove the tray. Follow instructions in the manual, though I did not see the need - it is pretty straightforward.

Step2.jpg
Here I lifted the tray up, but cannot completely remove it, because the wireless antenna (the white cable on left) and bluetooth antenna (black cable on right in the back) are crimped on their respective boards. Manual tells you to go ahead and remove them, but I do not have the right tools for it, so I left them on. The bluetooth card can be easily unscrewed, and Step3.jpg shows how to conveniently position the top of the laptop, so as not to damage it.

This is step3.jpg

Step4.jpg is my attempt to show you the wireless card, but I’m out of focus. Sorry. You remove it next just as you usually remove the memory chips, by parting the little clips on the sides, it’s pretty trivial. Note that I also removed the little black cover for the vga port - you need that to remove the motherboard. Step 5 shows the result:

Step6:

Step6.jpg zooms you in, so you could see the modem in the lower right corner - it is hidden by a whole bunch of plastic covers and papers with the specs, like inside a cabbage. Manual tells you to unscrew and unplug it from the usb port card that it is attached to. I found it unnecessary. If you have small fingers and fine motion control, you can gently unplug the black cable from the modem - you will find it hiding underneath that obscene flap of plastic on the far right, bottom.If you must remove modem in order to unplug it - then you will need to unplug the usb port card from the motherboard beforehand, that is the connector immediately to the left of the modem.

Step7.jpg :

Just removed the usb port card, but it is still attached to the motherboard by its cable. Also notice that the orange zif cable toward the bottom, which communicates motherboard with the second board underneath, is unplugged from the motherboard. It retains shape, like a standard copper wire, so you will be able to just unbend it, and it will stay that way. Be careful not to break it off, of course. When unplugging this little cable, I broke off the little plastic hair attached to its housing. That’s because I was clueless and did not read the manual, where it clearly says on page 4-4 that three types of connectors are used in this computer: pressure plate, spring, and normal pin connector. Well, this one it a spring connector, so you need to lift the yellow-colored stopper to unplug it. Take care to not let the stopper fly away, and notice its orientation. I just carefully left it there. Same applies to the big orange pc cable on the right, which connects hard drive to motherboard. Here the stopper is tiny, very thin and black. You know, I just left it there, because I was too scared to break the connector.

step8:

Step8.jpg shows what happens once you unplug the usb cable connecting usb port card to the motherboard.

Remove a few screws, and you get Step9.jpg: motherboard is removed. In my case it is still attached to the hard drive using a pc cable, but it’s ok. It’s out of the way. Now, do not make my mistake and remove all screws in sight in order to remove motherboard. I did that and lost contact between cooling fan and cpu, so I had to go remove the old cooling paste, put on the new one, which was a major pain, given the sizes of everything that had to get cleaned. Now the new cooling paste needs a break-in time of 200 hours, and meanwhile the cpu is running kind of hot. Thankfully this is a pentium m, and they can withstand temperature up to 100C. Anyway, only remove the screws the manual tells you to (I told you wrong in my previous post: here manual is actually correct). The one thing I did modify compared to manual, is that I did not unplug the power cable from the motherboard. That connector is very tough, and I did not want to apply too much force. The power plug slides right out of its housing in the body of the laptop, so I just let it do so, and you can see it kind of dangling in the upper right of Step9.jpg:

Couple more screws allow you to remove the hard drive cover - Step10.jpg:

The blue ribbon is the rubber enclosure for the hard drive, so it would not jiggle it its housing. Hard drive in this case has a mini-ATA connector, which is basically your standard ide, but small. It has regular pins, so you just unplug it from the cable - and that’s it, see Step11_1.jpg:

, Step11_2.jpg:

Finally, Step12.jpg shows you the unfortunate difference in connector of old hard drive (left, mini-ata) and new (right, zif connector). Like I said before, I ordered the converters to go from zif to mini-ata, and will post once I have accomplished something there.

step12:

This is it, folks. I love this little guy, it is so terribly cute, and pretty well put-together. I wish the designers would make a regular door for the hard drive, since it is literally sitting on the bottom, right next to the enclosure of the laptop. I am also put out by the fact that mini-ata 120GB hard drives do not exist. I understand that people are expected to just run windows on this machine, but even for that 60GB is a bit squishy. With 2 operating systems on it, 60GB is down right unsatisfactory. Anyways, enough druling - I will try to resolve this problem and post.
