日本Lenovo ThinkPad L13 Yoga Gen 4 (Intel) review – transformer with color-accurate display and near-silent cooling fan
Temperatures and comfort, Battery Life
Max CPU load
In this test we use 100% on the CPU cores, monitoring their frequencies and chip temperature. The first column shows a computer’s reaction to a short load (2-10 seconds), the second column simulates a serious task (between 15 and 30 seconds), and the third column is a good indicator of how good the laptop is for long loads such as video rendering.

The optional Core i7-1355U inside the Lenovo ThinkPad L13 Yoga Gen 4 (Intel) can show acceptably high clocks and power limits in short and medium loads. Unfortunately, the frequencies in longer loads are on the low side.
Comfort during full load
The power presets are integrated into the default Windows Power modes which seems handy.
When the system is in an idle state, the fan is dead silent because it’s not spinning at all. In heavy CPU loads, the fan is near-silent despite the ~3800 RPM rotating speed.

Now, we conduct the battery tests with Windows Better performance setting turned on, screen brightness adjusted to 120 nits and all other programs turned off except for the one we are testing the notebook with. The 46Wh battery lasts for 14 hours and 17 minutes of Web browsing or 10 hours of videos. To achieve that, you have to apply the “Balanced” preset in the Windows “Power & Battery” menu and set the “Scheme for Battery” to “Balanced” mode in the BIOS.
In order to simulate real-life conditions, we used our own script for automatic web browsing through over 70 websites.
For every test like this, we use the same video in HD.
