Bios T420

Hallo,

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.

 

Hello,

the bios for my laptop T420 (Win 10 Home 64 Bit) is Lenovo 83ET76WW (1.46), 05.07.2013.

It seems that Lenovo does not have an update here - with Spectre and Meltdown in the background.
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: https://www.cyberciti.biz/faq/update-lenovo-bios-from-linux-usb-stick-pen/
