Bios T420


das Bios für meinen Laptop T420 (Win 10 Home 64 Bit) ist Lenovo 83ET76WW (1.46), 05.07.2013.

Es scheint so, dass Lenovo hier kein Update bereit hält - und das mit Spectre und Meltdown im Hintergrund.
Eigentlich ein Problem für sich - gibt es hier für den T420 (BJ 2011) Lösungen?


Was ist zu tun, um das Gerät sicher zu halten  und um die Kompatibilität mit Win10 nicht zu gefährden?

- mit dem Gerät an sich bin ich sehr zufrieden und möchte es nicht austauschen.
Vielen Dank im Voraus für eure Hilfe.

Actually a problem in itself - are there any solutions for the T420 (built 2011)?


What needs to be done to keep the device safe and not to compromise its compatibility with Win10?

- I am very satisfied with the device itself and I do not want to exchange it.
Thanks in advance for your assistance.

Re: Bios T420

There's an update to address last vulnerabilities - BIOS 1.50 (83ET80WW), 08.03.2018. You can download an installation package for Windows 8 (it may or may not work with Windows 10) or create a bootable CD using this image.

Re: Bios T420

Thank you very much - worked - but only the ISO version has the latest bios - the exe version is about 2 years older.

Re: Bios T420

I can recommend to always use the ISO and not some insecure microsoft windows. When you dont have a optical drive and want to create a image with a propper OS, here is a howto:
