Some laptops may also offer UEFI options for adjusting Turbo Boost timing and parameters, though laptop UEFI is typically more locked-down than desktop parts. The advantage of using Intel’s XTU was that I got more granularity to play with the actual Turbo Boost settings, though this utility isn’t supported on every Intel laptop. I used Intel’s XTU utility for this, but there are other ways to disable Turbo Boost, including programs like Throttlestop. I figured two hours was all you could expect to get out of a gaming laptop, but since I wanted more battery for long flights, I decided to test the impact of changing the Turbo Boost parameters to see what would happen. Video playback was a bit better, but the laptop has a GTX 1060 in it, and GPU-equipped machines always use more power. When new, it got roughly two hours of battery life in normal use. to turn turbo back on and speed jumps above 2600 MHz and fluctuates around 3100 to 3200 MHz again.Here’s where I want to pivot and talk about my own experience with this trick. Then the turbo command is reversed: $ echo '0' | sudo tee /sys/devices/system/cpu/intel_pstate/no_turbo Speed drops to fixed speed of 2600 MHz which is the regular maximum speed without turbo.

Then the command is issued: $ echo '1' | sudo tee /sys/devices/system/cpu/intel_pstate/no_turbo gif sample below starts out by showing frequency fluctuating around 3100 MHz under heavy load when grep is running on the whole file system. With turbo boost enabled the frequency can jump to 3500 MHz under heavy load. In the example below the Skylake CPU has a regular frequency from 800 MHz to 2600 Mhz. Other answers mention alternate methods to the basic CLI (Command Line Interface). The returned 1 indicates turbo is now off. To disable Turbo Boost use sudo powers and set the switch no_turbo to 1: $ echo '1' | sudo tee /sys/devices/system/cpu/intel_pstate/no_turbo This is a double negative when 'no turbo' is off (=0) then Turbo Boost is on. Using the terminal you can check if Turbo Boost feature is enabled: $ cat /sys/devices/system/cpu/intel_pstate/no_turbo Maximum frequency 3500 MHz (3.5 GHz) $ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freqĬurrent frequency 1027.669 MHz (1.028 GHz) $ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freqĬPU 0 to 7 Frequency when YouTube loads up $ cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_cur_freqĤ out of 8 processors are in turbo mode (above 2.6 GHz) CPU 0 to 7 Frequency when YouTube paused $ cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_cur_freqĪll processors are at minimum speed of 800 MHz even though Chrome is running on two screens with 11 tabs open but YouTube paused. Minimum frequency 800 MHz $ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq This Intel Skylake processor is rated to 2.6 GHz or 3.5 GHz with Turbo Boost enabled.

The frequency is expressed in MHz with three decimal places. Alternate CLI methodsīelow you can see frequencies for CPU Number 0. Accepted top voted answer doesn't always workĪs the second top voted answer pointed out, the top voted and accepted answer sometimes shows the maximum regular frequency.
