无法缩放频率，总是跳到最低点
标题几乎解释了它。 我知道这不是硬件问题。 CPU是Intel Core Duo

我需要我的CPU能够达到它的2.4 GHz标记。 有人可以帮我这个吗？
显然戴尔使用的是调节CPU功率的芯片。
如果使用未经授权的充电器，Dell PC将阻止CPU电源。 这是一种迫使您只购买OEM充电器的糟糕方式。
要修复它，必须编辑/etc/default/grub文件。 在GRUB_CMDLINE_LINUX_DEFAULT行上，在splash之后但在结束之前添加processor.ignore_ppc=1 。
（例如： GRUB_CMDLINE_LINUX_DEFAULT="quiet splash processor.ignore_ppc=1" ）
