Lenovo ThinkPad T440s: unable to change bios settings

I've just changed the ssd (harddisk) of my Lenovo ThinkPas T440s, then installing Window 8.1 Pro on the new ssd.

To do that, I first changed the bios settings, allowing for legacy boot. Then I powered-off the machine from the bios (Disable Built-in Battery), so as to change the ssd.

Eventually, there was some problem with the bios, so I disconnected manually the internal battery.

Bios: LENOVO GJET89WW (2.39 ) 04/12/2016
Boot Mode: Legacy BIOS in UEFI
[ This is the lastest bios, obtained here: support.lenovo.com/fr/fr/products/Laptops-and-netbooks/ThinkPad-T-Series-laptops/ThinkPad-T440s/20AQ/CTO1WW/downloads/DS035965 ]

Now, when I enter the bios, I cannot change any setting. How can I fix that?

Do you see a lock signal when you try to enter the BIOS?

Yes.

If I put my old password, it doesn't work.

But if I just type the enter (or return) key, it enters the bios.

Re: Lenovo ThinkPad T440s: unable to change bios settings

That was the case.

Now (mysteriously), I can enter my old pass and change the bios settings.

However, if I do "Load default set-up" (including those recommended by manufacturer), exit and save, then:

The computer wants to boot by LAN, which it can't.

The only solution I found is to re-enable Legacy boot-up (option: both Legacy and Uefi).

What can I do to make it work with the recommended settings?

(As said, if load the recommended settings, it doesn't work, since it wants to boot by LAN, and then fail.)

I would need to see the settings, but my guess is that when you installed windows 8.1, the drive was set to be legacy boot and the default is uefi.

Yes, that's right.

So what should I do?

Re: Lenovo ThinkPad T440s: unable to change bios settings

I had a similar situation with a W540 and I intended to upgrade to win 10.  Here's what I did:

 

Do a full backup.  Run the windows 10 upgrade to get the serial number flagged as being upgraded by microsoft.  Download a fresh copy of windows 10 from microsoft onto a USB stick.  Wipe the hard disk   Set the BIOS to default settings with UEFI only.  Install the fresh copy of windows 10.

Re: Lenovo ThinkPad T440s: unable to change bios settings

Thanks, but I don't want to install Windows 10.

 

Would what you suggest work if I just reinstalled Windows 8.1 with the bios set as UEFI only?

I was on legacy thinking it was necessary in order to allow boot from usb (for installing from a usb key).

 

I don't want to go that path, since I have already re-installed everything (which took me several hours all in all).

 

I would have thought there is a way to work directly either on the bios or on windows 8.1 in order to solve the problem.

Any suggestion?

I don't have direct experience doing what you want to do.  Maybe someone else can help.

Re: Lenovo ThinkPad T440s: unable to change bios settings

If you installed the OS with Legacy Boot turned on, then you have to keep Legacy Boot on to boot into the operating system. The operating system expects the computer to act as a non-UFEI machine, and will refuse to boot in UFEI mode.

 

When you changed to UFEI, the BIOS failed to detect an operating system configured for UFEI boot. Thus, it attempted to boot by other means, such as a network boot. 

 

You can either reinstall with UFEI turned on, or you can load the default settings and then change it to legacy boot.
