Lenovo ThinkPad E14 Gen 5 (Intel) review – well-build comfortable business notebook
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 CPU here can sustain high CPU clocks and power limits in short and medium loads. In longer stress, the chip can maintain 2.20 GHz for the P cores and 1.62 GHz for the E cores which is a better result compared to the 16-inch HP ZBook Firefly 16 G10. However, the ThinkPad T14s Gen 4 and ThinkPad T14 Gen 4 are doing a bit better job in this section.
Comfort during full load
The power modes are integrated into the default Windows performance presets.
The single fan spins with ~1800 RPM during idle state, Web browsing, or video playback and it’s quiet. Under heavy CPU load, the rotation speed is 3600 RPM and the fan isn’t loud at all. In this scenario, you can feel a bit of heat beneath your fingers while typing but nothing serious. The two palm rest areas are cool enough for normal usage.

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 57Wh battery lasts for for 16 hours and 40 minutes of Web browsing, or 7 hours and 9 minutes of video playback.
Brightness: 180 nits; Display Mode: SDR
Time to Full Discharge: Higher is Better
In order to simulate real-life conditions, we used our own script for automatic web browsing through over 70 websites.
