Title:
Dell Inspiron 1420 without battery: processor.ignore_ppc does nothing
Status in “linux” package in Ubuntu:
Expired
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.
