I have been facing a strange problem that I cannot turn my dell inspiron 1420 off. The laptop turns on whenever I shutdown the machine. Only possible solution to turn it off was to remove the battery. I guessed that it would be a bios issue.
So I called the dell customer service. The customer care guy confirmed that it is a bios issue and instructed to download 1420_A10.exe file for flashing the bios. Unfortunately I hadn’t any dos boot disks to execute it.? But finally found out a solution to flash using GNU/Linux itself.
Here are the commands to make it work.
Use a pendrive to boot the freedos. Insert a pendrive and make it bootable
Create a file syslinux.cfg in /mnt/disk Add the following lines
Reboot and boot from the pendrive.
You can flash bios from pendrive :)
