IBM Thinkpad 760 reset BIOS password how?

[ali...@my-dejanews.com]

A customer dug up two quite antique Thinkpad 760 computers from the trashbin.
Thinks they make nice terminals for remote connections via modem.

1st Problem: long time ago someone set a BIOS password, and nobody remembers.
All printed documentation got lost too. How can I reset the BIOS password?

2nd problem: trying to get into the machine I failed to remove a 3 by 3 inch
cover on the backside of the computer. Probably the harddrive is underneath.
There is a small slider on the computer's side showing an arrow and a opened
lock symbol, and a larger kind of black metal clip towards the center of the
back with a plastic release I can press, but the cover does not go off. Since
I don't intend to break anything -- how can I get underneath the cover on the
back side, and what's there? Does it have teeth :-) ?

Thanks,

(1) Official answer is send the machine to IBM to replace the system board.
Only way to get around this as far as I know -- while there may be a way to
do this in the "field" but I haven't heard of it (and I've heard of folks
trying just about every possibility). General idea seems to be to make sure
a stolen system is unusable/unsalable by the thief; whether it's worth
anything in terms of theft-deterrance is a matter of opinion.

(2) If this is the cover I'm thinking of, it is on the bottom-right of the
machine, kind of to the front of being in the middle. (on the left if the
machine is turned upside down :) This cover is to access the memory board.
Push in the clip and slide the cover about halfway to the edge, then lift it
off. My 760CD has no cover on the "back" of the machine other than the
flip-down cover over the I/O ports -- and that's about 8 or 9 inches wide by
an inch high.

The hard drive on these systems is under the keyboard. Open the screen by
pulling back on the two levers on the sides towards the front. With the
screen open, now PUSH those same levers to the back to release the front of
the keyboard. Lift it up to access the battery, floppy, and hard drive
bays. (that little slider on the bottom-right has to be where it shows the
unlocked lock for this to work).

Forget it. I've bought the same machine (760EL) used and now I can't
change system settings, because some idiot didn't remove the
Administrator password. IBM says, that you can't remove it. You have
to replace the motherboard. Thanks, IBM. I'm not working for the CIA,
so I prefer a system, that can be hacked. We are only human. And
humans forget passwords from time to time.

If the system has a Power-on password set, you can remove it by installing a
jumper on the two pins left of the second-battery connector under the diskette/CD
drive. Just power on with the jumper in place.
If it was a Supervisor password there is no way to erase it. The prompt icon
tells you which password is set.

The cover you mention is for the memory DIMM sockets. It should just slide off.
(In fact the early design tended to fall off rather easily so maybe someone glued
it in place!)
