When my laptop is on my lap it enters a mode to generate less heat. This is fine 90% of the time but atm I am doing some benchmarking and I don’t know how to tell it that I need it to run in Performance mode so that I get consistent results.
I don’t believe KDE has any baked in lap detection, so I would assume it’s a BIOS setting.
Turn it off in there, stick it on a flat surface with plenty of airflow, fire a fan at if you can and let it cool to a steady state between runs, but I suspect you’ll still get some thermal throttling.
It is not location, but thermal conditions that control the throttling.
When running benchmarks it is highly advisable to have a laptop cooling station such as this to ensure adequate air flow for the high stress conditions.
Thanks! That’s a good idea but it’s a little too involved for what I’m doing.
I know it’s not locational but I just felt like it took too long (long enough that I rebooted for force it to) to turn off the setting after taking it off my lap.
This is where benchmarking gets hard - metrics are the only way to determine what caused a change in the execution, and then the next step is determining how to control them.
Benchmarking on a laptop is always going to be a bit of a lottery.
Here’s a gist started a couple years ago. Looks like this “lap detected” may come from your vendor and some kernel sensors. Might be a good starting point if you want to dig into this.
