If you are throwing it away, some heavy-duty gloves, safety
goggles and a crowbar may help.

Go to IBM.com ; enter your model number. This disassembly diagram
was about the 6th hit on the page.

I suspect the big clue is in the instructions for getting the rear
cover off :

Hidden screws. Lovely.

"No user servicable parts inside", obviously. But IBM has impressive
documentation, also for laptop disassembly. That does redeem them.

Right, "Prying off four snap-on screw covers" is obviously for pro-fessionals only.

> But IBM has impressive documentation, also for laptop disassembly.

So obviously "user servicable parts inside".

They'll be so glad that they have the babblebot's chary approval.

Idjut.

This is getting embarrassing. I have unscrewed the screws but they could not
be pulled out!

There seems to be some kind of detent at the end of the screw thread that is
preventing the screw from coming out.

The documentation said "captured screws". Does the word "captured" mean that
it is a special kind of screw?

Thank you all in advance.

Yes, it means it won't fall out to be lost. It should still be
releasing whatever it was holding-on to...

Hi
Here is how to loss off your hard disk out.
1. Screw off the screws with a star screw driver. Make sure you screw
off the four screws off your CPU.
2. After screwing off the case covers side by side.
3. Proceed to unscrew the section where the hard disk is located. It
is located the section where the Cd Rom, Floppy is located the front
of the CPU. This section has a total of eight screws in all that holds
the hard disk. The hard disk looks like a small box.
4. After un screwing ling it please note unplug the cables that is
connected to the power of your hard disk and the parallel cable too.
5. Then your hard disk is free. Remove it gently. Make sure your bare
hands do not touch the underneath of the had disk.
I hope this information will be of great help.

There are several ways of doing it, but "captured screws" normally
means that there's a washer somewhere on the screw's body that stops them
falling out and getting lost after their hold on the body of the device has
been released.

Not having the machine to play with, there is likely a series of
catches built into the plastic/ metal casing which provide most of the
mechanical strength of the join, and the screws hold the corners together.
So,
- locate a thin blunt knife ("butter knife" ; the bluntness stops you gouging
the plastic in the next step) ;
- observe the *side* of the casing near each screw as you tighten and release
it, somewhere you'll see the casing flex and a joint be exposed as the
tensions change ;
- slacken off the screws fully (they rattle in their holders), then push and
prod the casing until the loosest joint you identified above allows you to
insert the butter knife ;
- work the knife along the casing gap, popping open each catch as you get to
it (sometimes using one knife in each direction from the initial entry point
helps) ; observe catches three times before contemplating using more force and
you'll soon get a feeling for how well-made the case is. IBM machines are
generally pretty-well made.
- proceed as your experience dictates.

You've discovered an area in which you've not got the necessary skills
and experience ; you've asked for advice ; you've received it ; you're
practising on a machine where using a large hammer and a blow torch is
permissible (you said it's scrap) ; you're expanding your skill-set.
I don't see any grounds for embarrassment.

Makes certain assumptions about the users ; which might be
reasonable assumptions about the mass of users, but by the time the
machine has been turned over and the warning read, you've eliminated
95%+ of the population ... and in the remainder there are a fair
proportion of users who may be able to do servicing.
(This newsgroup is between several Sky-satellite-TV related
newsgroups in my offline reader, and a certain muggins is wondering if
the failed channel on the receiver might be a power supply issue, a dry
joint, or something else that might be fixable. All users are not the
same.)

This note is a year later. I do have experience working on the 6643.

The screws are behind a covers that pops off, use a screwdriver to pop the covers off.

The screws back out, but may not come all the way out. That's OK, as long as they are loose. Once loose, they may remain attached to the " Rear Cover" but they will not be screwed into the top cover. The Rear Cover attaches, or pops on and off. Once the screws are loose, grab the bottom of the Rear Cover, near the power supply or base of the 6643 and lift up gently. The cover should start to come loose. The Audio / USB jacks are attached by a cable to the Rear Cover and the Mainboard in the 6643, and you have to roll the Rear cover toward the Audio Jacks.

IBM - Lenovo maintains, I think, the best support site of any MFG of computers.

Go to IBM.com, click on the support tab, in the search window, type the model number, i.e. "664313u", without the quotes, and all the support info will show up. the left side will have Product Info, and other options.
There is a movie index on how to take the Rear Cover off and remove the hard drive.
The link is below.

If you still have the machine and want to get it up and running, I would need to know the symptoms to be of assistance.

Auggie.
