the 755ce is a 486. Maybe all you have to do is to reset CMOS. If
there is cmos battery, disconnect it for a few minutes and then
reconnect and restart the thinkpad.

There is something in the HMM (hardware maintenance manual) about
this. See the IBM web site and search around. I don't think you an
just disconnect the cmos battery, even on an old machine like the
755CE. Simplest method may be swap motherboards between the
machines.

Who in the right mind would purchase a laptop that the password couldn't
be reset by disconnecting the CMOS battery? As if you lost the password,
the motherboard turns to pure junk! No wonder IBM can't make it in this
world!


Cheers!

Most new laptops have this special "security chip" that cannot be defeated
by removing battery.
Only other option is new security chip or new mobo, unless of course, you
have an access to the previous owner.
I used once a guy who I found in Aussie, who could find out the password, I
found him with google and if I remember correctly, it was "joe from
australia"

People that want a laptop that makes it difficult for thieves to
make use of the stolen notebook?

Hi Benjamin! They do? Gee I would think they rather not have their
notebook stolen in the first place.

This is no bug, it's a feature. One reason why only amateurs and
idiots steal an IBM Thinkpad...

Well according to EV, even amateurs and idiots can bypass the geniuses
at IBM. Go figure?

Well I just did a Google search myself and according to JV, it can be
reset with a mere 1.5 volts being supplied to grounding pins on the
security chip. So much for security!

Very interesting. Have to try that on my own laptop ;-)

Most of the citizens of Hiroshima would rather not have had an atomic bomb
dropped on their heads either. What one would rather and what happens are
not always the same.

He didn't say what specific password it would remove. A Thinkpad can have
several. The procedure that he described will most assuredly _not_ work on
a hard drive password as the chip that he suggests attacking is not _on_
the hard drive.

Any idea where I can find instructions for disassembly? I've wrecked a
couple Thinkpads trying to get inside them. The cmos battery removal
doesn't seem to do the trick. I'd like to either change the boards, or
at least salvage the keyboard to use in my original one as that was the
major problem initially.

Thanks.

disassembling the antique is going to be tough, many intricate case
parts and boards. I currently can't find the service manual of this
model. It will have to be trial and error, with maticulous cataloging,
hopefully you will have enough good parts from 2 units to get 1 up and
working. best wishes.

Not that I really care, but who, and what, the hell are you talking about?

"Scumbag" I understand. We've got that one, too! <g>

It was the "nicking" that threw me. I thought someone scratched your laptop,
which made your post somewhat confusing.

Thanks for the clarification!
