I bought a broken T40!

#1 Post by beko1987 » Thu Dec 21, 2017 6:52 am

Not content with my little vintage 240, I spied this on ebay the other day, and after reading all the helpful info on here, decided it could make a fun project, so hit buy it now!

https://www.ebay.co.uk/itm/IBM-THINK-PA ... 2749.l2649

I'm going to try the oven method first, and basically see what happens! I'm less sure what to do with it if it works than if it stays broken, so watch this space! Ebay says it will arrive next week, so it'll be the new year before I do much with it! At least they showed it turned on so I know the screen and general machine does work.

Wow, hope that you will successfully get a full refund!

The eBay seller webpage did clearly state that it was in working condition...

Good luck!

That could indeed be a bad ATI Radeon 9000 GPU, I assume that's what you hope for.
I doubt baking it will do you any good, you need reballing for that.
In any case you can replace the motherboard with any T40/T41/T42/R50/R51 mobo and reuse all other parts.
You can also put in a "newer" T43/R52 mobo, but that requires different CPU and RAM.

It arrived today! Poor thing is filthy, and has a bit of damage to the wrist rest by the optical drive, but I'm not fussed about that for now!

First thing was to plug it in and confirm that the screen is indeed as garbled as it was on the ebay listing. I then hooked it up to an external display and that was garbled as well (just incase it showed the LCD was gubbed and not the GPU). I tried the wedge trick quickly using some post it notes and that did nothing...

Yes, my main aim with this is to try popping it in the oven and seeing if that fixes it, I've read about it a few times. For the price I paid, I'm not too fussed if it doesn't, as I now have 2 x 512mb sticks of RAM and an 80gb IDE hard drive I can find a use for, and buying those individually would cost more than the whole laptop.

Infact I have even less idea of what to do with it if I get it working than if it stays broken... It was just cheap, and I fancied a play!

Quite curious as to how it's ended up in Buckinghamshire, UK from Berkley, California! Came from a nanomanufacturing place called SINAM if that rings a bell with any US members? Luckily the power supply is 100v - 240v so I can just plug a UK figure of 8 cable into it.

Will have a look this weekend and see what can be done

Well, I've learnt lots tonight.

I've learnt how to take a Thinkpad T40 apart, it's fantastically easy to do with the manual! Mine has been bashed at some point, the top bezel has a corner missing, and the metal reinforcer behind the battery is cracked. But Meh, not it's biggest problem.

It's biggest problem was the idiot who forgot/didnt think to take ALL the stickers off before lobbing it in the oven for 6 minutes... Sticker curled and took many tiny components with it. RIP System Board...

I then learnt how to reassemble the whole thing so as not to loose anything, have 2 screw leftover that came from by the bluetooth chip somewhere, and one in the wrong place by the slimbay cage...

I also, thanks to Ebay, and £17 later have a T41 working system board heading my way...
System board assembly, ATI M10-64,
Gigabit Ethernet with security chip for
T42
v 2373-3Ux, 3Vx, 3Xx, 3Yx, 8Xx, 8Yx,
8Zx, 9Tx, 9Ux, 9Vx, 9Xx, 9Zx, AYx,
BUx, BXx, BYx, CUx, CVx, CWx, CXx,
CYx, JXx
v 2374-3VU, 3Xx
v 2378-DXx, EXx, EYx, FVx
v 2379-DXx
93P4158 N

My old board was 93p3842 which I can find no reference to in the service manual. No idea wether the board I bought is a downgrade or not but TBH it can't get more downgraded than it is now...

My £10 potential bargain is now at £27, oops. Was looking at faster processors earlier too, although that's on the back burner now! Found a 1.6ghz Pentium M, 1GB of ram and a Phillips 2.4/5ghz wifi card, and a modem/Bluetooth card. No idea if the hard drive works. Also, right at the end, I noticed the keyboard is in the US layout, which seems obvious considering where it came from. Not a huge issue though...

So, until this new board arrives, the project is paused

Your new mobo is a slight improvement!
You went from ATI Radeon 9000 with 64MB GPU-RAM to ATI Radeon 9600 with 64MB GPU-RAM.
For a fairly complete list of T4x/R5x mobos, see my website: http://theboardroom.info/ibm_list.html

Wonderful, that's not so bad then! Plus, being from a large (going by their feedback) seller if it doesn't work I can send it back!

Once it works it'll come apart again anyway for a good cleanup, and I'll see if it's worth spending another £10 on the few plastic parts it needs. I did find out that the power brick fits my old 240,which was kissing its one so that's handy!

Ive browsed your site before, it looks very familiar! Thanks for putting such good info out there, I can see alot of dedication! I'm a bit out if my league with thinkpads, I'm a vacuum collector myself so know how geeky one can get with these things!

Hoover. I read posts about people with 100+ thinkpads and don't laugh inside, because I have 100+ hoovers. Must do one tonight, might play with my little thinkpad 240 inbetween though!

Some progress! My T41 board came yesterday, so after dinner I got down to fitting it. Despite stern words it refused to fit itself

Image

So apart it came (much easier the second time) and I made use of the anti static sofa and anti static carpet

Image

Soon I had this

Image

Image

Image

Then 20 minutes later it was time to turn it on and see what happens, and the feeling was mixed

Image

Positive, it boots, negative, the screen is still doing that.

I nearly put it away and went to bed grumpy, then I remembered to check the VGA, so out came a cable, on went the telly and

Image

Fantastic, one issue solved! (I got garbled rubbish through the VGA with the old board.

Got stopped in my tracks though

Image

Some googling reveals this is a common issue and I need some sort of whitelist. Meh, that can wait. I popped it apart and had the Phillips wifi card out, back together again and

Image

Oooh. Got presented with a login prompt for someone called Rupert, but luckily the Admin account was unlocked so...

Image

And it booted up into a well used XP Pro install! (800x600 on a 50" LCD was a bit horrible, but I cant be bothered to install the graphics drivers yet) Runs nice and quick (it's a 1.6 with 1gb RAM), I confirmed the trackpad and keyboard worked, poked about with the LCD connector just in case and put it away and went to bed. It seems to have the original IBM install too (lots of IBM utilities, turning the ThinkLight on popped a message up etc) and I'm sure I saw a restore partition during my brief flick through.

Going to take the LCD apart and see if it's a simple connector issue, but posting the above on the Retro Machines facebook group, a lovely chap said he thinks he has a cannibalised Txx in his shed, which he will look for, so if that's cheap enough I might grab that off him and hopefully sort the LCD out and the bits of trim and stuff I need for the case.

It's progress though! Half tempted to boot it back up again, install TeamViewer and pop it by the router with a cat5 and play with it remotely. Or just leave it under the bed for another day

This may or may not be a good idea...

https://www.ebay.co.uk/itm/Job-lot-of-6 ... 2749.l2649

Hopefully, the bare minimum I can get is:

UK Keyboard

Internal metal chassis (mine is snapped)

Keyboard Bezel (mine is snapped)

Upgrade the CPU from a 1.6 to a 1.8ghz

A working WIFI card (the one currently fitted isn't on the whitelist so it wont boot with it fitted, cba to flash a whitelisted BIOS to it yet)

3 missing screws

Since the keyboard bezel is £4 on it's own, it seems good value (postage aside, I've man math'ed that out of my head...) There might even be a good screen, but I wont get excited about that yet. No idea about the rest, I'll give it all a good look over before condemning it, but in a way I hope they don't all work, the I won't feel compelled to keep them, and can part them out/turn them straight back around on ebay!
