Mark,
Are there just pads or are there pins on those pads? On a normal MB the
procedure to drain the CMOS is to short the pins with a standard jumper.
Try shorting the pins for 15 minutes with no power. If that has no
effect, try power with the pins shorted. This is quite a crap shoot.
Some MBs require a jumper on similar pins to enable a BIOS update so
there is no universal procedure.
BTW, I bought a 701c as well. Mine is pretty rough. The battery pack was
swollen and leaking so I need to open up the case and do some cleaning
before I get to see if I have the same problem.
I guess you haven't gotten to the point where you find out if Warp has
the drivers for the 701c or not. Let me know what you find.
Also... the CMOS backup battery is soldered? It's not a nice replaceable
button battery that you can just pop out and replace? Oh joy.

I'm trying to get a TP 701c I bought off of eBay
working to install OS/2
Warp on. But it has a password set in the BIOS. According to the
service manual ftp://ftp.software.ibm.com/pc/pccbbs/mobiles/tpvol2.pdf
there are two Power-On Password Bypass Pads on the bottom of the lower
system board, but no instructions on what to do with them. Do I need to
short them out? If so how? Someone else suggested desoldering the
backup battery, but if I can just short two pads, that would be
preferred. Right now its completely disassembled. I have two other
701c machines, but they each have their own problems. Worse case if I
can't clear the password I can try to take the display off this one and
put it on the 701c that has a display problem.
