I have been experiencing issues when connecting my P50 laptop running Linux Mint 19 to a ThinkVision LCD screen. Every so often the display goes blank and then comes back. Sometimes, the display comes back with the browser window resized. I was wondering if it was an issue with the BIOS version I am running.
I looked and I am running NIETT60W 1.33
I see that there are newer versions of the BIOS and ID ownloaded the n1wwr83w.cab (1.56) file and tried to install, but it tells me that my bios is not compatible as it requires a version greater than 0.1.46.
I looked and see that there are older versions, but they are CD images. If I understand correctly I can burn an image to a DVD and boot-up choosing the boot device to be the USB DVD player.
My question is do I need to go all the way back to 0.1.34 and version by version upgrade my bios? Or, can I go to (I hope) 0.1.46 and
upgrade to that and then from there upgrade under Linux to 0.1.56?
Many thanks for your help and hope your day goes well,

My ThinkPad P50 is away from me right now, and I don't run Linux on it, myself, but I did note that Lenovo does have a Linux-based BIOS update utility now for it.
Have you tried installing the Lenovo P50 BIOS Update v1.56 using the Linux utility available for download at https://support.lenovo.com/us/en/downloads/ds106108?

Thanks for the quick response. Yes, I tried the Linux utility, but it says that the version of my BIOS (0.1.33) is not compatible with the cab file version. My BIOS needs to be at least at 0.1.46. Looking at the older BIOS I see that they are ISO images and I can boot to a DVD device fine. But, I wonder do I need to upgrade every increment from my version up to 0.1.5X, or can I skip versions as the changes are included in newer versions?
One line of thinking would be 'try it and see', but that assumes that the developers (all excellent people I am sure) have made the code idiot proof.
Hope your day goes very well,

yes indeed I do have LVFS, but the older versions of BIOS are ISO images which is also fine (I don't think I can use iso images with LVFS unless I do some magic to convert them to cabinet files). I would like to know if I need to install all the images oe-by-one or I can skip some versions.

It has been years since I've done anything with Linux, so I don't have any suggestions about running the BIOS updater in Linux, per se, but as far as the ISOs go, perhaps you could try using an .ISO which has an update half-way between your current BIOS and the latest version, and seeing if that upgrades successfully. If it does, go ahead and then try updating to the latest version of the BIOS.
