I have a - Dell Inspiron 6400 - with Bios revision A3.
[1] After a 2 months of use, grub would hang while booting. The countdown to boot would not work. [2] Today I changed BIOS settings for the second time. The system will not boot anymore and simply displays "Time-of-day clock stopped" message. Haven't tried pulling the coin cell battery yet. -- Ubuntu corrupts real time clock on some dell laptops https://launchpad.net/bugs/43745 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
