Re: Y50 70 BIOS Can't Save Settings Or Exit

All,

 

This has been an interesting thread to follow for one of our engineers who has been trying to but, unfortunately, not been able to reproduce the issue.  Would anyone like to offer a method of reproducing / causing the issue?

 

Thanks in advance,

 

Andy

Andy,
it is not that easy.
For some it happen because of their permanent changes of Linux distribution, others using rolling release with daily kernel updates and most of others - without any specific pattern.
You do need to run like a hundred of kernel updates with GRUB/EFI writes to discover if this is affecting you.

I am also affected. :(

4 days ego I was Installing ubuntu 18.04 developer version.on my Lenovo E40-70
I was running win 10 upgraded from 8.1, I erased my hard disk and tried to install ubuntu with new partitioning from ubuntu install wizard. and while installation I got 'grub efi boot error' and installation failed. then I tried to:
 boot windows DVD or Flash stick to install windows but it failed ."USB flash disk boot failed"
 boot ubuntu 16 or 17 or even 14 with DVD or flash failed."USB flash disk boot failed"
BUT I only can but into ubuntu 18.04 and go to installation process(which has error while installing) or go with ubuntu live.

I tried everything but nothings work!!!!
hard reset bios, iso image, rEFind ,..... but nothings works.

the bios does not saves the changes and the bios setup is allways is on UEFI mode.

Also the bios recognise my hard disk but I dont have it in boot menu I think it is because I dont have OS on HDD but I have a PArtiallyn failed ubuntu installation on that.!!!

is there any idea how to solve it myself or even send it to repair shop?
I called USA and Germany customer service and they have no Idae!

Hello 

This issue is easily reproducible on Lenovo Z50-70 model 20354 :

1/ Download the latest ubuntu stable

2/ put it on a bootable usb and boot from it on the Z50

3/ tell ubuntu you want to install

4/ when asked, tell ubuntu to use the full disk

5/ answer yes to all questions telling you you might not be able to start another system and such

6/ optional : once ubuntu is installed completely, if you want to brick your laptop like me, just take the drive outside and trash all partitions from it, you wo'nt be able to change you bios settings and install any other operating system

 

That's what just happened to me...

I read that flashing the bios again might reset it (https://forums.lenovo.com/t5/Linux-Discussion/Ubuntu-17-10-corrupts-Lenovo-BIOS-USB-not-recognized-not-saving/td-p/3887679), but you only provide a windows flashing utility, and I was unable to enter the bios recovery mode it seems, I tried formatting the usb drive to FAT32, extFAT and NTFS, renamed the file isflash.fd to ACLU1X64.fd and put it alone on the usb drive, tried the Windows+D and Fn+R key combinations when pluging the laptop in (without battery) and powering it on, no luck there...

Dear Colleagues.

My system/BIOS is revived. But I cannot tell definitely, what is the root of unlocking it.

I'm willing to describe the procedure I think led to recovering it but I prefer to share it with one or two capable people, to prove it is working. If it does the trick I will post it here. Since my laptop is no longer affected I cannot work on a simple(r) solution therefore I need at least two volunteers.

What is the risk - none, if you won't mistake console parameters.

What is required:

- laptop with the no BIOS save issue and fully operational LINUX system

- second hard drive (not USB but the SATA disc!!)

- readiness to use screwdriver to open your laptop

That's it.

Please PM me and tell me how skillful you consider yourself with Linux console tools. I will write the step by step guide in response, bit chaotic because I did it by accident and don't know, what would be the shortest way to achieve it.

If you don't have working Linux, don't know too well how to use console - please WAIT until we confirm the solution. I don't have time, patience etc. to hand-hold everyone. (bit bitter but experienced strange stories after posting my rEFInd workaround!).

Anyway.

Hope over the weekend we will have solution to some of you!

Marcin

I have neither a second hdd not a working Linux on the laptop. But I know my way around a Linux console, have no fear of screwdriver (have already tried to clone partitions onto the hdd by taking it out and using it on my desktop through USB to data adapter)

So if you have no other candidates for helps I'm willing, otherwise I'll just wait patiently ;)

Thx in advance.
