In an area where most budget machine’s cut back, the Lenovo G580 offers an acceptable level of performance. Equipped with a 2.5GHz Intel i5-3210m processor and Intel HD Graphics 4000, the Lenovo G580 easily tackles basic computing functions such as word processing and basic web-browsing.
With 4GB of RAM the machined does an admirable job of multi-tasking, as I was able to watch multiple video streams without any noticeable lag or drop in performance. However, running more demanding processes (such as a complex excel spreadsheet) will greatly diminish the notebook’s ability to juggle multiple applications.
While the machine performs well with basic functions, the notebook will struggle with visually intensive processes (such as gaming or video editing) due to the limited capabilities of the integrated GPU. However, the Lenovo’s lack of GPU performance is to be expected at its low price point and users will have no issue completing most processes.

Heat and Noise
The Lenovo G580 is surprising quiet given its large bulky form factor. The singular fan located along the left side of the chassis (with additional vents on the bottom of the device) does an admirable job keeping the device comfortably cool under normal conditions. The fan does become audible at times when the notebook is pushed to capacity, but even then it produces only a faint noise. Small burst of heat can emanate from the vent during these occasions; however, it is never server enough to hinder the user’s experience, and the notebook can still be comfortably used as a laptop if desired.
To test battery life we used our new PowerMark benchmark in balanced mode. The test consists of a combination of automated web browsing, word processing, gaming and video playback workloads. The test is far more strenuous than our previous test, measuring the machine under a litany of scenarios to better simulate real life use. With the test being far more demanding the scores are understandably lower than our previous benchmark.
PowerMark batter life test results (higher scores mean better battery life):
In our tests the Lenovo G580 ran for 2 hours and 47 minutes before shutting down after reaching the 5 percent battery reserve. Just shy of the three hour mark the Lenovo G580 does not offer strong battery life. Users expecting to run the Lenovo for any prolonged period of time should have the power adapter on hand.
While having to carry the power jack in addition to the machine is a hassle, it doesn’t come as a surprise that the Lenovo G580 doesn’t offer strong battery life. With the lack of durability and its larger form factor portability isn’t a focus for the Lenovo G580, so the weak battery life shouldn’t be a huge hindrance.
