Heat and Noise
To gain our temperature results we ran our most intensive benchmark for 45 minutes and then took readings with an IR temperature gun. There results were about average. The lowest reading was 78 degrees Fahrenheit and the highest was 96 degrees, which was found on the bottom-middle of the notebook. Ninty-six is not extremely high, but it is something to be aware of. The exact temperature readings (listed in degrees Fahrenheit) can be found below.

The noise levels on the G570 are about average. When the notebook is stressed, you can hear the fan running and making a low murmur, but it is not what I would consider a distraction or annoyance.

Battery Life
The Lenovo G570 has a 6-cell Lithium-ion battery (10.8V, 48Wh). During our battery tests, we set the Windows 7 operating system to the “balanced” power profile, adjust the screen brightness down to 70%, turn the wireless on and connect to a network, and refresh a web page every 60 seconds. The G570 was able to last 4 hours and 32 minutes on these settings. This is above average for a notebook in its class running these hardware specifications, so we were pleased with the results. Of course, that number will go up or down depending on a number of factors such as how badly you’re stressing the notebook, screen brightness, etc.

Battery life test results (higher scores mean better battery life):

We believe the Lenovo G570 would make a good general use notebook to have around the house if you are in need of a lower-priced notebook. The combination of its performance, keyboard and touchpad, solid build quality of its chassis and battery life cover all the grounds to make it a decent system. The complaints we did have about the display and slower hard disk drive will not be big enough deterrents for people if they simply want to own a decently solid secondary or budget-priced notebook. There is also an extensive amount of ports for an entry-level notebook, including more than enough USB 2.0 ports, e-SATA, VGA, HDMI, and a media card reader. The G570 is available now through Lenovo and select retailers, starting at the Web price of $449.


  • Good performance
  • Great keyboard
  • Very decent audio
  • Solid chassis build quality
  • Good battery life


  • Washed out display
  • Slower hard disk drive

    The fatal flaw in the G750 is the hinge, which failed in my laptop after less than 1 year of light use (and no travel) due to very poor design and plastic parts. I discovered that it would cost $90-100 to repair this at local computer stores. I have researched this problem online, and find many posts complaining of failed hinges. Also, these posts report a complete lack of response from Lenovo in repairing this, even for laptops still under warranty. It is amazing that Lenovo doesn’t care enough about there customers or reputation to repair the hinge and fix the problem! You should include this in your review!
