Toshiba Satelitte 4000CDS teardown

In this video we're going to be taking a look at my Toshiba Satelitte 4000CDS.
Not the best laptop (in fact pretty terrible), but a good laptop to experiment with and see if we can completely disassemble it without doing any damage.
Stay tuned for part 2 where we will clean and assemble the laptop again and have some fun with it

The thing that was flying around inside was the ferrite housing of the little inductor right beside the power connector as can be seen at 14:14 in the top right corner.

You can keep the glued plastic covers and stickers intact when you you use a heatgun with low heat and peel them off with a needle or something similar. Nice Video as always.

[@cdos9186]

You know what is crazy? To think that every single one of those components had to have been put in at some point when the laptop was manufactured. I've never seen so many parts in a laptop or ever really thought about it. Thanks for the great video!

[@youdud44]

I absolutely love this era of Satellite laptops, especially my 335CDT. I had the same problem with corrosion from the Varta battery on a Pro 460CDT that I learned to take apart, even in the connector to the motherboard, but luckily the leak wasn't as bad as yours.

[@ToddSAFM]

I like the tear-down/restoration angle. Fun. I’m just glad you’re the one putting it all back together.

[@dav1dbone]

I made up a patch cable that plugs into the parallel port to reset password (think it was for the bios), works on quite a few models, needless to say it's sat unused in my parts bin for years. A nice, robustly built, range of laptops - the Librettos of the same (slightly younger) era were very similar, lots of pcmcia accessories too.

[@maxtornogood]

Both the leakage and the teardown itself were extensive, kudos to you! I don't picture myself entirely disassembling a laptop because it probably wouldn't go back together due to me being slack & probably careless.

[@lordmithras47]

To remove that screw, on the CPU assembly you can try the following: 1. place the flat side of a rubber band into the stripped screw hole (similar to this: kzbin.info/www/bejne/oJa4fZZ6erimi7s) or 2. if you have a modular screw driver set, super glue one of the tips into the stripped screw Hope this helps. Look forward to seeing the part where you can this stuff. One more question: are you going to see if you can't replace that horrible LCD screen with something else?

[@RetroSpector78]

Might give that a try. Don't think you can replace the screen so easily. But have a couple of other Toshiba CDT models so will take a look.

[@Inject0r]

@@RetroSpector78 if those fail, you’ll have to get the dremel out I guess. And make it compatible for a flat head screwdriver. I’ve enjoyed this video very much. I’ve got a Toshiba 486DX4-75 laptop lying around in a container, also disassembled. And also with the same kind of dreadful display. On mine the PSU is built in and capacitors need to be replaced. Also in the screen, so that’s quite the challenge. We’ll see how it goes! The three batteries aren’t particularly needed to be able to boot it. Although, it might be very interesting to at least replace the CMOS battery with a double CR2032 battery and a diode. That’s what I’m doing on mine. The rest really aren’t interesting to preserve. The battery for powering the laptop can easily be removed from its cover/cage, so the laptop will be a bit lighter in weight. Good luck on your project!

[@amirpourghoureiyan1637]

@@RetroSpector78 Gorilla glue or baking soda with super glue might help, adding a little bit between a spare screwdriver should expand the adhesive and fill the worn away thread to get a good grip again.

[@mima85]

4:04 - That is due to the hard drive heads being stuck to the platters, and as the spindle motor has very little torque it can't overcome the head's friction force and spin up the disks. Removing the drive from the laptop subjects it to vibrations and small hits, that are enough to make the platters move a bit, freeing up the heads and finally making the drive to be able to spin again.

[@dykodesigns]

That Toshiba bootscreen brings up some memories from my first internship circa 2002. I had to use one of those (or similar model) running Windows 95 to do some basic AutoCAD drafting on. It was slow and not ideal for the task.

[@RetroSpector78]

Think this is my only Pentium 2 based Toshiba. All others are first gen Pentium (MMX) class. too bad for the screen.

[@DaveM245]

Another great video! I love the early Toshiba laptops, I now have two. With Phillips head screws, they are designed to be put in with a machine, when it reaches a certain torque level the bit is designed to ride up and out of the screw, so if you need to apply more torque to remove the screw the bit will try to ride up and out and strip the screw head. The screws may actually be J.I.S screws ( Japanese Industrial Standard) even if they are not, get yourself a set of J.I.S Screw Drivers from E-bay they will fit much better. Here is the description from E-bay, Premium JIS-4 JIS Screwdriver Set Japanese Industrial Standard Drivers New The Phillips screw drivers are more pointed on the end and the J.I.S screw drivers are more blunt on the end, if you have some bit sets you may already have some. Regards, Dave.

[@ivandiazalvarez]

Being a Toshiba laptop these screws can be SJIS which are like Phillips but-not-quite. I usually have no problems unscrewing them with Phillips but the cam is different. Usually SJIS screws are marked with a dot in the head though.

[@jdmcs]

I’ve had similar experiences with small screws. Sometimes you do everything right and the head still strips out. It’s possible that was a cheap screw. It’s also possible that someone else has been inside this laptop and they started stripping the screw head. Once those screws start to strip, it can be very hard to keep it from happening even if you realize you were using the wrong driver and then go back and get the correct one. As a last resort, I’ve dremmeled a slot into screws to get them out. Not sure there’s enough room in your case to try that. And this is risky - you get metal bits everywhere, you risk damaging the screw head (and possibly making things worse), and you’ll probably have to find a replacement screw.

[@RetroSpector78]

Yeah ... thought about it, but too risky. Perhaps when I'm done with it and have no more use for it.

[@LuxorVan]

Just get a #2 phillips for that screw, I often avoid those little kits with changeable bits unless I'm working on something with small torx or flathead screws. If you are out looking for a few decent screw drivers avoid plated ones and look for ones with blackened tips.

[@mikatorkkeli4932]

Hey those are good laptops. I supported them for many years in a corporate environment, not the best but damn they gave there best over the years. Still have two of them and still works :)

[@86smoke]

Regarding that screw, I found it fairly common for screws located neat major heat sources become baked to threads, especially when screw glure was used (Toshiba uses stronger red glue while most of manufacturers stick to blue one). I'd recommend hitting the screw through a screwdriver with a hammer couple of times (supporting it firmly from the other side of course). It may break some baking inside; I call this technique 'negitiations' :)

[@RetroSpector78]

Was not aware of that. Thx for the info.

[@laszlomarktoth7492]

I seen a better idea on KZbin some days ago, melt some solder in the top of the screw, when it's filled the hole stick into a right bit and wait a bit to cool down, and voila you can untight the screw again. Regards Mark

I have a dozen of awesome laptops from 1995-1999 era but they all have the same issue: terrible displays. For this reason I stopped collecting them, but it's a real shame, would be cool if it were possible replace them with some new ones, as for old handheld consoles, but I guess this is pretty much impossible due to the vastity of sizes and different/proprietary connectors they have 😕

[@RetroSpector78]

Think most of them can't be easily converted to an active TFT. You can always mount it under an external monitor and have a cool little retro setup :)

[@framebuffer.10]

@@RetroSpector78 yes sure, but this somehow defeats the whole laptop thing purpose because you probably also want an external mouse and keyboard to be more comfortable and at this point you better use directly a midi tower with proper video/sound cards and everything 😅

[@nickwallette6201]

The TFT screens actually aren’t too bad. You just have to find a model that is using TFT (active matrix) instead of STN (passive matrix). The latter aren’t worth the glass they’re adhered to.

[@herrv1906]

Having its cousin, the Toshiba Satellite Pro 4010CDT (266 MHz instead of 233 MHz and TFT instead of DSTN), it is a pretty capable laptop for DOS gaming. Besides that, its OPL3-SA sound chipset is pretty good as well. If I remember well, I have another one (440CDT) who has a dead motherboard due to similar corrosion issues. 😂

[@RetroSpector78]

Also have a couple of CDT laptops... indeed much better. That's why I tried experimenting with this one. If it goes to hell not much is lost :)

[@MrRadioAct]

I second the DOS gaming comment. I had one of these laptops back in the day and it was amazing to have both the floppy and cd rom built in! Ran many dos cdrom games flawlessly. Good to see that the LCD is just as bad as I remember it was....

[@sleveee]

the screw stuck in the aluminum heatsink is likely corroded in place. it looks like there has been some liquid in the laptop so that screw will be welded in place with white corrosion.

[@slabo8171]

I'm not so brave guessing how to disassemble a laptop, having some bad experience in breaking parts in the process, so I always try to search for a service manual. It can be easily found for this model, in the case of Toshiba it is named "Field replaceable unit documentation". It's terse, but it contains disassembly photos.

[@RetroSpector78]

Found it after I created the cover photo with all of the components sitting on my desk :) Next time I'll google first :) But it was pretty straightforward. Hope the assembly process will go well and I don't forget the component that needs to be put in in step 3 when I'm at step 78 :)

Have a couple of thosiba's with TFT screens and it is indeed a world of difference. I do think these Toshiba's have this iconic purple look and feel that contributes to its retro factor.

[@MarkTheMorose]

Ah, the question of what to do with old laptops... If the horrible screen can't be replaced with one using a superior display technology, might just as well remove it and use the machine as a 'half-top', connected to an external monitor. A Pentium II with 32MB of RAM and sound should, at first glance, be a reasonable system for retro games, but the onboard graphics may limit that. Since it has USB, serial, parallel, floppy, and CDROM, it could be a useful way to bridge between even older systems, and modern ones for file transfer.

The screw may have lost its chemical properties by being too close to the processor and heatsink, generating a lot of heat and it ended up getting too hot where it couldn't stand it and started to soften. *** O parafuso pode ter perdido suas propriedades químicas por estar próximo demais do processor e do dissipador, gerando muito calor e ele acabou esquentando demasiadamente onde o mesmo não suportou e começou a amolecer.

[@Pickle136]

thats one gross laptop. I have a ibm with a passive display and ive wonder if the screen itself could be swapped out. But i had doubts how universal the connectors are. as a last resort on the screw you might try a power drill with a small bit in it. Ive found it can bite into the screw and move it. Once it breaks the locktight it comes easy. another tactic with those glued covers heat up with hot air and then peel. You can find examples of this when guys are removing the badges from cases to retro bright them.

[@RetroSpector78]

Think in most cases it will be a different connector. If you're lucky the motherboard might accept both options but depends on the model. Not sure if I'm going to try and do something with the broken screw. Very close to the CPU :)

Oh my gosh, this computer was in horrible shape! And this computer clearly wasn't designed to be serviced, no technician would want to go through all this much work to fully disassemble a machine, the laybor charge alone to do all this would be at least 500 dollars minus new parts!

[@mima85]

It's actually the fact that you could fully disassemble the machine to its tiniest bits that defines its serviceability. While being quite labour-intensive, on those old laptops you could replace almost everything. Maybe a technician would have spent a couple of hours to replace a component because it was buried inside the machine, but we also have to remember that the cost of the laptop featured in this video would easily break the 3'000$ barrier in its years, and that with a passive matrix screen. With active matrix you were easily into the 4-5'000$ territory, if not even more. With a laptop costing that much, in perspective a 500$ bill for technician labour is not that much. That was the norm with 90ies laptops. Today's laptops, where often not only RAM and CPU but even the SSD is soldered on the mainboard, while being far simpler buildwise they're are also far less serviceable. And as they're quite cheap, at least the low/midrange models, they get thrown away even for issues that could be easily repaired, like a dead battery that today often is not user replaceable as you have to disassemble the machine to reach it.
