A laptop for a little less than 800 Euros (~$1099) should have more to offer. It has a bluish cast, low contrast, and is only averagely bright. However, HP manages to ruin the rating by installing an unacceptable screen. Beyond that, we like the tool-less opening of the maintenance cover. HP has also installed decent input devices in the ProBook. HP's ProBook 450 G1 E9Y58EA provides high application performance and operates quietly. The DVD test is performed using enabled energy saving profile (or a higher profile should the DVD not run smoothly), maximum screen brightness, and disabled wireless modules. It places itself between the TravelMate (3:34 h) and ThinkPad Edge (3:03 h) with that. The ProBook shut down after DVD playback after 3:10 h. Websites are opened automatically every 40 seconds, the energy saving profile is enabled, and the screen's brightness is set to roughly 150 cd/m² for this test. Thus, it lasts longer than both the TravelMate (4:30 h) and ThinkPad Edge (4:23 h). The ProBook stopped the Wi-Fi test after 4:48 h.
Here, the screen works with maximum brightness, the high-performance profile is enabled, and the wireless modules are on. The load runtime is ascertained using Battery Eater's Classic test. The TravelMate is on par with 1:05 h, and the ThinkPad Edge did a better job with 1:31 h. The ProBook achieved a load runtime of 0:59 h. The screen is set to minimum brightness, the energy saving profile is enabled, and the wireless modules are off. Idle mode is ascertained using Battery Eater's Reader's test. We did not perform this test with the ThinkPad Edge. The TravelMate shut down earlier (8:13 h). The Probook's battery lasted for 9:39 h in idle mode. Therefore, the Cinebench benchmarks scores are, for example, lower than in AC mode (Cinebench R11.5 single: 0.97 multi: 4.79).Īlthough the ProBook sports a standard mobile processor (not ULV) with four cores it supplies good runtimes. The processor always operates with a maximum of 2.2 GHz in battery mode.
The CPU's temperature settled to approximately 75 ☌ in AC mode (stress test). Even if the processor barely used its Turbo in the stress test, it does in routine use as our performed benchmarks prove. The stress test presents an extreme situation that does not occur to such an extent in routine use.

The graphics core always ran at full speed (1150 MHz). The CPU ran stably at 2.2 GHz when the stress test was performed in battery mode. Recurrent peaks of 2.3 and 2.5 were recorded.
The CPU performed the stress test (Prime95 and Furmark run for at least one hour) with 2.4 GHz in AC mode. The temperatures of both the ThinkPad Edge and TravelMate remain below 40 ☌ at all measuring points. It only surpasses 50 ☌ at the measuring point in the fan's area. The ProBook only heats up moderately in most areas during load. The temperatures were within an acceptable range at all measuring points. None of the three comparison laptops heat up notably in idle mode.
