I had purchased this Dell Inspiron 14 3421 in January 2013, working all well. It came pre-installed with Windows 8 and had BIOS version A03. At that time I could change the maximum CPU speed in power management settings, it could run at half speed around 900 Mhz.
Currently I'm on Windows 8.1 Pro and BIOS version A12, and now there is no CPU speed setting in power management settings. Thus my CPU is running at 1.80 Ghz all the time, whether I'm running word or browsing. Because of this issue & the age of my laptop, it now gets hot after some time of usage. I have 8GB RAM on my laptop.
Is there a way I can lower the CPU speed when there is less load on the system?
Everything is up to date on my laptop, installed the chipset driver again but nothing happened. CPU is still running at full 1800Mhz speed. Even at times when there is low load.
