Unable to access bios from CMOS

I have installed mint on g580 but cannot get into bios from cmos, removing hdd drive and battery and motherboard battery and pressing power button did not help as suggested by lenevo forum. The system do not recognize the windows or any recognized operating system except the system mint live usb itself. or windows original dvd drive any version. Yep upgraded version but that was in windows 8 but after switching to mint there is no way i can flash phonix bios into the system as all the files available is in windows exe format. tried wine but not successfull. no i did not retain the old bios backup. any way other then changing the motherboard itself

I wonder if the motherboard's manufacturer has something for you on their website that maybe can flash from bios instead of running in OS. Thats how my Gigabyte board is, not sure what is in the Lenovo laptop.

you should contact or drop an email to the motherboard vendor. I hope the BIOS chip is not corrupted.

You can update BIOS via USB, I just did. The CD image from Lenovo is not compatible with USB, you need to modify it, then you can boot from USB. The magic word is El Torito (google it if needed).

Depending on you OS, you need to
- download the CD image for your laptop from the Lenovo site
- extract the "El Torito" boot image from the CD image you've downloaded
- flash this boot image to an USB drive
- reboot your laptop and boot from this USB drive

I'm using Arch Linux, and used to extract the bootable image, and used dd to copy the image to USB.

It would de nice if Lenovo supports updating BIOS from USB directly (they don't obviously, requiring you to either use Windows or have a USB-CD drive)
