The battery life is rarely the most important decisive factor for buying laptops with a quad core CPU. Thus, Asus doesn't even try to boast with a big capacity. Instead, it uses a common 47 Wh battery (4400 mAh). It's almost baffling that it's capable of more than just changing the location, between living room and office.Acer Aspire 7730Z   Battery,

The WLAN session already comes to an end after 2:00 hours (120 minutes). If you're frugal, you can end up with 2:39 hours (159 minutes) with disabled WLAN/Bluetooth. We determined this idle runtime with the BatteryEater Reader's test (lowest brightness). Acer Aspire 7730ZG   Battery,

A Blu-Ray or DVD movie don't make much of a difference. The movies ran for a short 81, respectively 89 minutes (luminosity 100 cd/m2). The 17.3 incher even needs longer for a full recharge: 2:06 hours (126 minutes).Acer Aspire 7735  Battery

In previous tests, Core i7 notebooks with four cores have always had a higher energy requirement than Core i5 devices. Acer Aspire 7735Z  Battery This isn't any different in this case and is promoted by two hard disks. The N73JQ needs a minimum of 19.3 watts (idle, maximum energy savings). The CPU doesn't downclock in an idle scenario in high performance mode (1.73 GHz) and makes the power consumption climb to 29.5 watts (wireless on, maximum brightness). Energy savers should therefore always use Battery Saving or Quiet Office (Asus Power4Gear modes).Acer Aspire 7738  Battery,

A 17.3 incher with an i5-520M can be more restrained in idle with 14 / 21 watts (min / max) (Samsung R780-JS03DE). Consequently, the N73's 460M alternative will draw significantly less power from the mains.Acer Aspire 8730   Battery

The heavy 120 watt adapter hasn't been included without reason. When the Core i7-740QM and GT 425M compute with full power (stress test), the effective power increases to 117 watts. Such a high power consumption won't be achieved in 3D games. 3DMark06 runs with 77 watts.Acer Aspire 8730G  Battery

N73JQ: Powerful soundAsus sets up a 17 inch entertainer with the N73JQ. Aspire 8730Z   Battery The laptop scores with acoustics, ergonomics and application performance. Sonic Master with ICEpower isn't just hot air. Contrarily, it's a notebook sound that outshines most multimedia laptops. We have to massively reproach the basses, which aren't powerful enough in our opinion. Asus also places the case's haptics and robustness on a high level. Stiff lid, stable aluminum surfaces and matt plastic - all of this radiates high quality and longevity.Acer Aspire 8730ZG   Battery

The high contrast FullHD display (1920x1080) with stable horizontal viewing angles is perfect for movies, pictures or games. Nevertheless, reflections (glare type due to edge to edge design) and a narrow color spectrum disqualifies the Hannstar screen for professional use.Acer Aspire 8920   Battery

The latter wouldn't be impressed by the spongy and somewhat crowded keyboard, either. In return, the equipment is impressive, despite the lack of an ExpressCard54: eSATA, USB 3.0, HDMI 1.4, two 500 GB hard disks, three RAM bays (up to 12 GB) and a BluRay burner make the 17.3 incher fit for the future. Asus additionally has moved a few interfaces to the rear, which results in a cleaned up desk.Acer Aspire 8920G   Battery

The Asus N73JQ-TZ087V is suitable for ambitioned cineasts, who are looking for a state-of-the-art notebook with an appealing FullHD screen and very good sound. They can also start with the full versions of PowerDVD9, PowerDirector V8, MediaShow Espresso and Video Magic (CyberLink) right away. Acer Extensa 7230  Battery

If 1270 euro is too expensive for you, you can also buy the i5-460M model, N73JF-TY060V, for 1020 euro. Video converting is a bit slower, though (40% under certain circumstances, see performance). The general application performance will only differ slightly. Acer Extensa 7630  Battery
