Alistair Buxton, if one simply reads from the release notes of your hardware from the link I sent you, it's pretty clear your BIOS has bugs (and is in turn insecure): https://download.lenovo.com/UserFiles/Driver/en/Downloads%20and%20Drivers/S10-3T/Tem/24CN62WW-win.txt
The date of release is not a reason to delay upgrading if the OS relies on keeping ones BIOS bug free.
