After the Lenovo splash, it presents "This Computer Has Been Locked"..."Your SIM card has been removed or damaged. Please replace the SIM card or enter the unlock password." Cannot proceed to BIOS or anything else. The SIM card is indeed missing, but that can't be the real issue here, can it? What kind of password is it asking for? Could it be a SVP? I've never seen one present this way before. I have not been able to find any info in the HMM or elsewhere about anything other than the usual three kinds of passwords (POP, HDD and SVP), so I'm turning to you knowledgeable folks for info.
Here is a screen shot...if that helps.

BIOS Option ROMs can do interesting stuff. Case in point: CompuTrace. If activated, CompuTrace will look for Windows partitions on every boot, and inject executables into the file system so it can run inside Windows. The Windows component then phones home if internet connection is available, report its geographical location, and in case the laptop is reported stolen, wipe the hard drive.
The hardware RAID support in W-series is also an Option ROM. I won't be surprised if there is an Option ROM that checks the existence / identity of an inserted SIM card.
The usual BIOS upgrade images do not contain Option ROMs, therefore BIOS upgrades will not overwrite them.
That said, have you tried simply removing the WWAN card?

Yeah, I've tried that, and it made no difference. Still get the same "locked" message.twistero wrote:That said, have you tried simply removing the WWAN card?
Anyway, thanks for sharing your knowledge. If anyone comes up with other ideas...please let me know. I don't have to overcome this obstacle, but I would like to.
Alternatively, insert a SIM card (active or otherwise), and see what happens. It seems unlikely that even if the BIOS remembers that there was a SIM card inserted, that it also recorded the SIM card's details.
Tried installing an inactive SIM card, and the T400 did recognize the new card, but still wanted a password to unlock the machine. So no real difference between no card and new card.
By means of nothing less than a lucky guess, I tried a password that seems to have worked! It passes the computer locked screen and goes to a P.O.S.T. screen that reads:
Code: Select all
Phoenix SecureCore (tm) NB for ThinkPad Copyright 1985-2009 Phoenix Technologies LTd. All Rights Reserved (C) Copyright IBM Corporation 2001, 2005 All Rights Reserved (C) Copyright Lenovo 2005, 2009 All Rights Reserved
Last line of the screen is "To interrupt normal startup, press the blue ThinkVantage button"
If I do nothing, it will reboot and ask for the SIM password again, and repeat the same cycle.
If I press F1 at the Lenovo splash, enter the SIM password, it goes to the POST screen with the bottom line "entering setup"...then reboots repeating the cycle, but never actually entering the BIOS setup.
If I press F12 at the Lenovo splash, enter the SIM password, it goes to the POST screen with the bottom line "Preparing Boot Device List...", then reboots repeating the cycle, but never displaying a boot device list.
I was exited about discovering the password, but bummed now because I'm really no farther along getting it to boot than I was with the system locked.
Is the HDD indeed bootable? If uncertain, then replace with a known bootable drive, and see what happens. Perhaps it will boot if the HDD is bootable, even though it won't present you with a boot device list or let you enter the BIOS.Neil wrote:... If I do nothing, it will reboot and ask ...

Here's a T400 with UEFI implementation instead of a BIOS.
It is called the Phoenix Fastboot, which boots in about 10 seconds! http://www.youtube.com/watch?v=DLwaKb6p ... r_embedded
Maybe yours is also a prototype for something?
What's the MTM?
Why don't you ship that machine to me, so I can play with it for a while?

Since I really don't have time to mess around with this right now, I just might send it to you.
