David Nemeskey, as per
http://www.dell.com/support/troubleshooting/us/en/19/Product/inspiron-1420
an update is available for your BIOS (A10). If you update to this, does
it change anything?

If not, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Thank you for your understanding.

Title:
  Dell Inspiron 1420 without battery: processor.ignore_ppc does nothing

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I have a Dell Insprion 1420 (Core 2 Duo @ 1.8GHz), and the battery has
  recently died. Because of this, the CPUs have been downclocked to the
  minimum frequency, 800 MHz.

  I have tried the workaround described in bug #706089 (Frequency scaling doesn't work in current kernels) and on various pages around the web, namely, adding the processor.ignore_ppc=1 directive to grub. However, it does not have any effect: my CPUs are still running at 800 MHz. The bios limits (/system/cpu/cpu*/cpufreq/bios_limit) are set to 1801000, so that should not be a problem.
