The Libretto is the father of today's netbooks, this little laptop can support up to 32MB of RAM memory and 2GB of HD. There's the support for an external screen thanks to his docking-station, and it has a bundled floppy drive too!

Difficulty: Medium

Special: Comparison between Libretto and iPod Touch!

    • Say "Hello" to Libretto!

    • This is very small, the dimensions are about 21x11,5x3

    • The best OS fitting inside it is Windows 95, the base RAM is 16Mb (yes, that's 16!) and the bundled HD has 810Mb of memory.

    • There is no floppy integrated, only a PCMCIA slot, a IR port mapped as COM2, a mini-jack for audio (back), a speaker, the power connector and the base attachment.

    • The screen is about 6", 16-bit color, the backlit is powered by a CCFL light as usual in LCDs.

    Now I discovered that it's not enough illuminated... I have to buy a good lamp.

    DO you think is possible to "upgrade" the speaker, or perhaps adding a 2nd one on the other side of the screen, making it stereo?

    Thank you.

    The only upgrade I am thinking about is a real computer. There is no space for a speaker here, and besides that the audio would suck equally.

    • Before starting with screwdrivers it's better to remove first the battery.

    • It's like nowadays notebooks, move the slide-button and pull the battery.

    • The battery-pack contains 9 batteries, as usual 1.2v each 1200mAh; that makes 10.8v, enough to power the HDD, the PCMCIA, the screen and the processor at the same time.

    • The model number is: PA2497U

    • Let's have a look at the chips

    • That's right! The northbridge is made by CHIPS; T6550 A1 GVS60030 9651-b made in KOREA (the last is the serial I think)

    • The CPU is an Intel Pentium PP75 Y856 75Mhz

    • There's another chip with a stick attached to it; F36000 476002

    That’s not the northbridge. That’s the VGA. Chips & Technologies 65550.

    • High definition shots of the motherboard.

    • Note that's it is using the multi-layer technology, patented and seen on some other models such as ZENITH Systems, this allows the boards to be much smaller, but it's very hard to see the tracks.

    • The screen! Not easy to open.

    • First remove the glued tapes at the bottom, so you can access the two screws that hold the upper part.

    • With a screwdriver take away the MousePad.

    • The pad is nice to use, confortable and easy to handle, you only have to get a little pratice, notebooks have abandoned this kind of pointing device from years, but in my own it's still excellent.

    • Now you can see the screen, the power elevator for the lamp, the controls and the speaker.

    • Don't touch any part of the left circuit, it's dangerous to touch it because it handles high voltages for powering the CCFL lamp; take it from the edges and handle carefully.

    • Unscrew where shown with a Phillips cross screwdriver.

    • Carefully move the screen to access better the rear cables.

    • Time to tear out the screen cables.

    • The first is quite easy to take away, the same thing as part-8 (see pict.2)

    • Paying attention not to touch any contact, detach the CCFL cable by simply pulling it.

    • The screen is very small, the maximum real resolution is only 640x480, actually the minimum for Win95.

    • Because the screen is old it contains mercury, and the cables may contain BFR, so try not to break anything.

    • Time to separate the cable from the plastic cover.

    • There's a sticky sheet that is keeping held a little piece of plastic, remove it.

    • When done you can pull out the cable.

    • Et voilà! The work is done!

    • This wasn't very hard, but reassembling is not as easy as opening it.

    • As you see the little PC is still working perfectly.

    • And now a little comparison to the iPod Touch 3G

    • Results are that the iPod touch does more, costs less and is that simple..! (I've already heard it somewhere)

    • I hope you enjoyed the guide, if you have any corrections, tips, additions or reproaches please post them!

Very nice teardown! The relative ease of disassembly of such a tightly integrated machine is impressive.

jjacocks - 답글

Nice job.

Since you have disassembled everything, could you tell us what’s the exact model of the screen?

I have also a Libretto 50CT and I’m looking for a screen replacement.

caiot5 - 답글

I believe it is a Sharp LQ61D133
