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?
Thanks. But this doesn't seem to be the solution. I can boot in Windows 8.1 all right. But I can't change the bios settings. I can also flash various bios from within windows (using their exe's). And I have the latest bios. My problem is that I can't change the bios settings. In particular, it is stuck at Legacy boot. I'd like to change it back to uefi boot. And I'd like to be able to use the bios normally, which I can't currently.
Thanks. So what should I do? The F9 key has no effect, indeed I said, I can't change any setting the bios.
