    Default Lenovo T460

    Hi a friend of mine bought a car from COPART, in the boot of the car was a Lenovo T 460 Thinkpad. He rang the guy told him he left the Thinkpad in the car. The guy said it was a works PC and had left the company a while ago. The problem is how to get around the supervisor password to activate the BIOS. ive seen how to do this on other Lenovos but not this model? Anyone know how to do this or show me a link PM me if its possible without changing the motherboard PCB. Thanks Flexy.

    Hi MHP ive tried clearing the CMOS using the battery method. This hasent taken out the supervisor password to allow me to operate the BIOS so I can change the boot up to usb. The BIOS is locked. All the disconnect battery done was reset the time and date to default.

    Yes if you listen to the video Mick its for older PCs. Those are just before the T460. It says in the vid newer models use a different methods to unlock the BIOS.
    Thanks for the prompt answer. I was thinking the bios might be on a non programmable pic or eprom not sure though im no expert. It has to be around you would think to be able to service the Thinkpads?

    if your any good at soldering just replace the bios chip i've done it a few times

    Flashing the bios generally won't remove the password

    When buying the bios chip make sure it is pr programmed and not sent blank eBay is your friend

    Thanks to fanni

    I presume the hardware ID will be created when you read the BIOS.

    Thanks to neilb

    The procedure is on the page I posted, you need to read the bios with a SPI flash programmer and send it to them along with some other details.

    Have you replaced the chips on Thinkpads Fanni? I was under the impression that the only option for these was the link Neil posted.

    I bought all that kit last year and have struggled to get it working, it requires a device with a native LPT port so I bought a Thinkpad T40 and after spending countless hours working on it with the support of the allservice owner, he said it must be a dead LPT port on the laptop so I bought a T43 which arrived today and am working on that now.

    Based on my experience, probably worth just selling it as-is as this has cost me a packet so far (the cost of the kit, two laptops, two pomona clips). Even if you only had to buy one laptop you need to take into account sourcing one, paying for that, the SPEG hardware, the service charge for modding the BIOS and your time.

    Thanks to evilsatan

    Thanks for the info evilsatan I was just trying to help the guy out. Your right anyone could go on spending to fix the problem. It was just to have programs on in his garage anyway. Cheaper to pick up a second hand PC. What would happen if I just formatted the HD? would the BIOS not look for the boot up auto if I installed the H/D blank. Im sure its locked on booting up to the companys system. If not its maybe the bin.

    It depends which passwords are in place, if there is just a BIOS password then you can usually enter BIOS by pressing enter whilst the password is blank so you can see the settings (read-only).

    Say for example that SATA was set to AHCI, and an external ODD/USB and the HDD/SSD appeared in the boot order, then you can tap F12 when you start the system to enter boot devices and then boot to a Windows installer and reinstall Windows to have a functioning laptop.

    If the option to boot to an external device was disabled then you could extract the HDD/SSD, put it into another system, check that the SATA operation mode matches what is on the T460 and install Windows from install media (delete all existing partitions during this install), after the first stage of the install where the files have been copied from the installer and it reboots you could power off that machine and put the drive back into the T460 to boot from and complete setup.

    I think that if there is a HDD password then you can format the HDD to remove but if there is a power on password I am not sure what can be done.
