so, I flashed the file attached here: http://www.elektroda.pl/rtvforum/topic2452833.html and everything works now! the "ubuntu" entry has been automatically deleted and I was able to access BIOS and change the boot order.

BEFORE INSTALLING!!!

write down MAC address of your LAN card, because it'll get deleted after BIOS update!

1. press windows key+R, type

cmd

and press Enter

2. in the opened command window, type

ipconfig /all

and press Enter, find the entry regarding your Ethernet connection and write down the physical address

3. flash BIOS update

4. after reboot follow this guide: http://www.addictiveblogs.com/how-to-change-mac-address-windows-7-windows-8/

Hello all,

In case you didn't see - Lenovo have finally released a new BIOS for the Z580. This fixes the accessing bios issues and allows you to disable secure boot etc.

Not bad after saying that no BIOS updates would be available.

If you still have trouble you can obtain a single file version of the bios that works as well (use google) but you will need to use the pheonix UEFI flashing tool.

I see a bios update for win 8 will it work on win 8.1 ?? 

so I just updated the BIOS with the file available on Lenovo's site. my Z580 didn't want to boot after flashing the first file. in case someone has got the same problem:

1. turn off your laptop

2. remove the battery and the power cord

3. insert the power cord back in (do not insert the battery back)

4. hold insert key and press the power key (still holding Insert)

5. be patient, a grey popup should appear, asking you to choose the device you want to boot from (HDD, CD, USB etc.); don't choose anything, just

6. press Tab, and select Setup. the BIOS options will appear

7. scroll to Advanced (if I remember correctly), and switch boot type from UEFI to Legacy

8. save changes and exit. you'll be able to boot in Legacy mode.

I can't make my Z580 boot in UEFI mode though. when I switch back to UEFI in BIOS options, the laptop stays on black screen and I have to do a force shutdown.

I also noticed that the laptop has got more brightness levels than previously, but the on screen indicator still shows 10 levels - so after the indicator reaches level 10, I can still make the screen brighter. weird.

Is there any chance Lenovo might provide this bios update as an .ISO file like they do for the majority of their machines?  Have removed Windows 8 in favor of Arch linux, and there is no way to use these .EXE files

Hi All

I bought this lenovo z580 laptop on 28 July 2012.  Now i got Hinges problem, when i tried to find solution for this on this website i came to know that many are facing same problem here.  I called lenovo support they are saying the hinges problem is not covered under the warranty. 

Since many Z580 users facing same problem. It is definatly build quality issue with this series of laptop. So lenovo should respond to this and try to resolve customer issues on this regard.
