Review Asus K75DE Notebook, 90XB00CN-MPW060 Batteries

Outwardly ASUS K75DE LAPTOP is identical to the Intel-based: thus we find the simple lines, clean and streamlined as the first, with the keyboard cover to isolated elements and covered with a texture IMRpattern in relief. The only difference is the plan keyboard which was in the first aluminum alloy, while here again be in polycarbonate. Also in this case there is also the large touchpad with the integrated keys under the sensitive membrane, as well as the technology Asus IceCool, which provides for the arrangement of the hardware components warmer away from the contact areas of the body, so as to preserve the comfort of use even after sessions of work or leisure stays.The display is identical to the Intel-based and therefore is 17.3 inches with a resolution of HD + with 1600 x 900 pixels.
Another point in common also affects the type of audio system SonicMaster Lite, a simplified version of the processor and void Bang & Olufsen ICEpower , which is usually found in high end models of the Taiwanese media, combined with speakersAltec Lansing . Also here we find the new Asus SuperBatt batteries, which provide an average life of the battery 3 times higher than standard technology and Asus Super Hybrid Engine II with instant on feature, which allows the K75DE out from the stand-by in just 2 seconds and will automatically back up your data when the battery drops below the 5% remaining.

Battery Life

While idle, Asus K75DE Notebook trumps both the Samsung 355E7C-S05DE and the Sony Vaio SV-E1712F1EW in the Battery Eater Reader's test (minimum brightness and WLAN off). The Asus lasts a great 8:12 hours. In the WLAN surf test, the test model ran a good 4:08 hours, once again leaving the competitors behind. At load and during DVD playback, the gap decreased. The high power consumption values start playing a noticeable role. Taking into account the 50 Wh battery of the K75DE (largest amongst the models we have for comparison), the test model performs quite poorly (Samsung 48 Wh; Sony 44 Wh).
Asus presents a new 17.3-inch multimedia notebook in the form of the K75DE-TY068H. This category is already filled with multiple contenders, like the Samsung Series 3 355E7C-S05DE or the HP Pavilion g7-2051sg, which also use the AMD Trinity APUs. In addition to these two, we will also use the Sony Vaio SV-E1712F1EW, which runs on Intel hardware but has the same size and price class, for comparison.
The real star here is the system's battery life. Asus has always had some of the longest-lived Netbooks, and the new 1005HA got an impressive 6 hours and 51 minutes in our video playback battery drain test--about 30 minutes more than our previous leader, the Eee PC 1000HE, and more than 2 hours better than the nonremovable battery in the 1008HA model.

Case

The notebook is made entirely of synthetic material and kept in black, which appears metallic due to its surface structure. This grants the laptop a certain visual appeal and the material is comfortable to touch. The synthetic material is covered with the aforementioned structure and is susceptible to fingerprints and smudges, which are quite visible.
The case and the display can be pushed inwards with little force and are prone to creaking. The display is especially sensitive and we recommend handling it near the middle. The two hinges are sturdy and hold the display well. Opening the notebook requires both hands.

System Noise

The Asus K75DE/K75VD is a relatively quiet notebook. While idle, it does not get louder than 30.8 dB(A) and the cooler fan remains off for the majority of the time. The hard drive is also quiet at 30.4 dB(A). This makes Asus a better choice than the Samsung 355E7C, which has a higher noise emission.
The DVD playback test paints a similar picture. At extreme load, the Samsung model performs better than the ASUS K75DE/K75VJ, as it never gets higher than 39 dB(A). The Asus notebook can reach peaks of up to 44.1 dB(A) in the stress test (Prime95 and FurMark). This is a maximum emission and will rarely occur in everyday use.

Temperature

While idle, the surface temperatures of our test model never rose above 33 °C. Sony shows us that it is possible to do better with its 17-inch model which never got hotter than 28 °C. At load (stress test), the competitors swap positions and the Asus K75DE/K75VM stays 4.6 °C cooler. Asus boasts of their cool hand-rest regions and have dubbed their clever positioning of the hardware: "IceCool". The notebook can live up to the claim and the hand-rest regions never get warm (even at full load).
During, the CPU stress test with Prime95, the CPU temperature never rises above the 66 °C mark. The clock speed fluctuates between 1.9 - 2.3 GHz at the start, and during long periods of high load, is known to drop momentarily to 1.4 GHz. This short-term throttling does not explain the poor benchmark results (in comparison to the Samsung 0335C1960). The clock speed of the Samsung competitor drops to 900 MHz. In the combined stress test (Prime95 + FurMark), the CPU temperature rises to 78 °C. Right after the stress test, we ran the 3DMark 2006 benchmark, which recorded a lower score (-797 points) than in the "cold" state (before running the stress test). The throttling of the 7670M is responsible for this poor performance, as this chip falls short of its base clock speed of 600 MHz by about 146 MHz.
If the laptop is on battery mode, all cores process at a constant 1,414 MHz. The GPUs present similar behavior. With the power adapter, they operate at 334 and 655 MHz, but once the laptop is running on battery, the speed drops to 277 MHz.

Energy Management

The Asus K75DE/K95VMrequires maximum 18.4 W while idle, which places it slightly higher than the Samsung 355E7C (17.1 W) and the Sony SV-E1712F1EW (17.0 W). All in all, the power consumption is still slightly too high.
At load, the trend continues: our test model consumes far more than the competitors. We generated full load using Prime95 and FurMark and measured between 72 - 85.1 W on the ASUS K75DE/K84H. The provided 90 W power adapter has enough juice. The similarly-equipped Samsung notebook consumes 54.5 W in the same conditions. It is worth noting that the 355E7C suffers from CPU throttling at full load. Still, even the Sony Vaio requires a max of 62 W.
We really like the consumption while turned off. The laptop required 0.0 - 0.1 W while off and 0.3 W in standby.

Connectivity

The connectivity of the Asus K75DE/K84HR is acceptable and conforms to that of the competition. Only the Sony SV-E1712F1EW sticks out of the pack as it has one USB 3.0 port less (but makes up for it with an additional USB 2.0). The positioning is well-planned. The ports are far enough from each other so that they do not block each other when in use.

Communication

The Asus K75DE/K84HY uses a RealTek Gigabit-LAN interface which works quite well. The wireless networking is achieved using a Qualcomm Atheros WLAN module (AR9485), which supports the 802.11 b/g/n standards, and has a max transfer rate of 150 MB/s. It operates on the 2.4 GHz frequency and has good range. The connection was stable even up to 10-12 meters from the WLAN router (Fritz!Box 6360) and could deliver a transfer speed of up to 16.5 Mbit/s.
Bluetooth or WWAN are not to be found. The integrated VGA webcam has a resolution of 640x480 pixels and suffices for VoIP. The integrated microphone works well and the input is clear even 1.5 meters away from the notebook.

Keyboard

The flat, wide keyboard, similar to what we saw on the Eee PC 1008HA, is among the better Netbook keyboards we've used, and the full-size right Shift key is one of those things you don't realize is very important until it goes missing. The touch pad is demarcated by a rectangle of raised dots on the wrist rest, and works well, although we found ourselves going into the touch pad settings and jacking up the default pointer speed.

A single quick-access button above the keyboard is for disabling the touch pad (handy if you're using an external USB mouse), and Asus' different preset power profiles are accessible by hitting the FN key plus the space bar. New to this model is a software suite that acts as a software dock popping out of the top of the screen (by default, but switchable). From there, you can access functions such as screen brightness presets and media players. Most Netbook users we talk to are no-nonsense types who just want to surf the Web or send e-mail, so learning the ins and outs of a proprietary menu bar system may not be high in the list of priorities.(ASUS 70-NXM1B2200Z BATTERIES)
Touchpad
The touchpad of the K75DE measures 10.5 x 7.4 cm and is very well-dimensioned. The smooth surface has good sliding properties and is very precise. The bottom part of the touchpad includes two mouse keys which have good pressure points. The stroke distance is good and multi-touch gestures are supported. (ASUS 15G10N373800 BATTERIES)

Display

The 10.1-inch LED display offers a 1,024x600 native resolution, which is standard for a Netbook, although higher-end systems are starting to add 1,366x768 display options. The backlit LED allows the lid to be very thin, and also use less power than a more traditional LCD display.
The average brightness of 223 cd/m2 is slightly lower than that of the SAMSUNG AA-PA2N40L (244.7 cd/m2) and the Sony Vaio SV-E1712F1EW (244.1 cd/m2). The illumination is balanced and there are no bright spots. Photographers or other users, who want accurate color depiction, will not be happy with this panel as the color space coverage is too limited for professional use.
Performance
The Asus K75DE/K84L uses an AMD A8-4500M APU, which is based on the AMD Trinity architecture. The platform is equipped with 4 GB of RAM and a 500 GB Hitachi hard drive - conventional hardware. The IGP (Integrated Graphics Processor) of the model is a Radeon HD 7640G. When more performance is required, a Radeon HD 7670M (CrossFire) kicks in. From the performance, it seems Asus is aiming for buyers who need a laptop powerful enough for everyday tasks and occasional gaming.

Verdict

The Asus K75DE/K84LY offers sufficient performance for everyday tasks and has enough left over to sate the needs of the occasional gamer.
The more notable addition on this Eee PC is Nvidia Ion graphics. Though automatically switching Nvidia Optimus technology isn't available on this Netbook, the dedicated Ion GPU significantly helps with HD video playback and streaming. Full-screen Netflix looked very good; ABC's Flash-based video player also looked great. Hulu in full screen was choppier than that, but still very watchable. If nothing else, Ion turns this Eee PC into a video-capable machine--something that many Atom Netbooks really aren't.
Games can also be played, within reason. Unreal Tournament III ran at 27.4fps in native 1,024x600-pixel resolution, and we found other casual or older mainstream games to be very playable on the Eee PC 1015PN. The one big drawback, other than the small screen, comes from the increased fan-blown heat that billows out the side of this Eee PC when using GPU-intensive tasks such as Flash 10.1 streaming-video playback.
Photographers should avoid this device as the display does not live up to their needs. This Asus model is aimed at buyers who do not want a desktop PC and are looking for a cheap laptop with a large screen. Buyers looking for a similar notebook based on Intel hardware will want to take a peek at the Asus K95.
