Hi, Have you checked this link? Requires some work to construct this little circuit
(easily sourced from junk boards as diodes/resistors are jellybean items and a connector
chopped from serial cable laying around that you have too many of or get one from
Saver/Value Village for few bucks.) and bit of disassembly of thinkpad, not too bad to do
and it is required. The IC is small SMD 8 pin with Atmel as shown in the FAQ.
Make 3 wires disconnectable/connectable with some way of connectors from junk pile so you
don't have to be so careful connecting/disconnecting right on the chip itself in live
thinkpad.

Data is too important so have to do this done to unlock a thinkpad.
Cheers, Wizard

Dan,
You seem to be missing the point of my request for help.
1. The laptop is worth about $50.00, I'm not spending $1200 to recover data off the
HDD, and neither is my friend who it belongs to. She is upset losing the $100 it cost her
two years ago.
2. The laptop doesn't boot. It asks for a password. This is in the BIOS. It can't
be bypassed to boot from floppy or CD. Without this password, the system is bricked. There
is no way to recover it other than changing the logic board and HDD. Since all I want is
the HDD data, that is not the solution.
There is a way to recover the password, but nobody will tell me where the TPM chip is
located on the 600e logic board. I don't want to just take the laptop totally apart. I
want to take as little apart as possible.
I'm hoping someone knows the IBM master password so I can get into the bios and reset
the system. Barring that, this system is junk.
Thanks anyway.

take it to a data recovery place, ask for a free estimate.
be prepared to pay $1200 or more.
as for the CMOS, you can still wipe it.
remove the HDD, then boot either floppy or CD that would bypass that password,
would also confirm exactly how it is locked.
you can still try to contact IBM for recovery (for a large fee I suspect)
otherwise you're SOL
Dan.
