Build and Design
The K40IN has a traditional notebook design and shape; it looks like an ordinary notebook and is visually uninspiring. Corners are rounded off to give the notebook a soft look. Nearly all surfaces of the K40IN save for the keyboard are glossy plastic, which is a dual-edged blade. On one hand the glossiness makes the notebook look more attractive, but on the other hand it reduces durability and makes it a real chore to keep clean.
The physical build quality of the K40IN is satisfactory. The quality is consistent; no particular area seems to be stronger or weaker than another. The base of the notebook resists twisting well and the palm rests barely flex under pressure. This lid is one of the better-reinforced lids I have seen on a value-oriented notebook; it is resistant to flexing and pushing in on the back of the lid does not yield any ripples on the screen. The hinges anchoring it to the base of the notebook are strong and display wobble is minimal.
Overall the build quality meets expectations; it is not outstanding and matches up to the competition at the very least. The design is rather plain though not unattractive. However, the glossy plastic will be a turn-off for some.
Screen and Speakers
The K40IN has a 14-inch diagonal display with LED backlighting and a 16:9 aspect ratio. The overall quality of the display is 'very good'. Brightness is excellent and contrast is reasonable. Pictures and movies are a pleasure to view on this display. The viewing angles are above average; side-to-side are nearly flawless, and while the colors wash out and darken from above and below respectively, the picture is fine for about thirty degrees vertically off center. The backlighting is not even with a significant amount of bleed at the bottom; fortunately it is not noticeable during normal use.

The display's 1366x768 resolution is a standard resolution for mainstream notebooks. The horizontal resolution is adequate, however only 768 pixels of vertical space means a good deal of scrolling while surfing the Internet and only enough space to view about one-half of a page in a Microsoft Word.
The K40IN has Altec Lansing speakers located underneath the palm rest. Simply put, the K40IN has two of the worst speakers I have heard on a notebook; my ears cringe every time a sound gets played. The speakers are muddy, tinny, and too quiet. Using the included SRS WOW software enhancer distorts the sound and put this odd pressure on my eardrums that I cannot stand. The headphone jack is fortunately static-free and the best way to get audio signals out of the notebook.
Keyboard and Touchpad
The K40IN's full-size keyboard is responsive and pleasing to use. The keys are large and flat and have a matte texture, which may wear over time. There is no noticeable flex unless a lot of pressure is used. A nice aspect of this keyboard is its quietness; it does not click or clack. It is also good to see the keyboard has a standard layout; all keys are more or less in their expected places.
The touchpad is a mixed bag. The glossy surface can be difficult to track on with moist fingers and the touchpad buttons are loud. Another complaint is the lack of a dedicated scroll zone.
The status lights on the K40 consist of three tiny circles below the touchpad buttons. From a functionality standpoint, they should be larger and brighter for better visibility.
Ports and Features
The K40IN suffers from a lack of ports relative to its competitors. HDMI is noticeably absent; the notebook's only video out option is VGA. Furthermore, there is no ExpressCard or PC Card slot for wireless broadband cards and other add-on devices. All picture descriptions are left to right.
Left side: DVD drive, 2x USB
Right side: headphone and microphone jacks, 2x USB, VGA out, 1000Mbps Ethernet, power jack
Front: Speakers, media card reader (SD/MMC/MS)
Back: Kensington Lock slots, exhaust vent
Performance and Benchmarks Wprime processor comparison results (lower scores mean better performance): PCMark05 measures overall system performance (higher scores mean better performance): 3DMark06 measures overall graphics performance for gaming (higher scores mean better performance): HDTune storage drive performance test: Graphics performance from the integrated Nvidia G102M will only suffice for older games; newer games are out of its league. Despite having 512MB of its own memory the G102M simply lacks the processing power necessary to play modern games. I question ASUS' decision to use Nvidia graphics in this notebook versus Intel integrated graphics, which have lower power consumption. The extra power consumption of the Nvidia graphics versus Intel graphics is not justified since this machine cannot play modern games and its HD video acceleration capabilities will go unused since the K40IN lacks a Blu-ray drive. Something to note about the Intel Core 2 Duo T6500 processor is its lack of VT (Virtualization Technology). This means that the K40IN will be unable to utilize the virtual Windows XP mode in Windows 7. For most users this should not be an issue. Heat and Noise The heat exhaust fan is located in the center of the back of the notebook. This is a convenient location since it keeps heat as far away from the user as possible. The fan is nearly silent even when under load, and is barely audible at idle in a silent room. Well done, ASUS. Battery Life Operating System and Software Conclusion Pros: Cons:
The K40IN is a good performer thanks to its Core 2 Duo processor, 4GB of RAM, and speedy 320GB hard drive. This machine is more than capable of handling everyday tasks and even more intensive applications like Adobe Photoshop.
The K40IN excelled in managing heat and noise. Even under stress the surface of the notebook never got warm and the palmrests remained completely cool – there is even a sticker on the palm rest showing this off stating "Feel the cool comfort – 25% cooler than body temperature." The bottom of the notebook also remained cool, only getting warm in a few areas.
In power saving mode with 25% screen brightness, the K40IN lasted for four hours, thirty-five minutes while surfing the Internet and using a word processor. This is a good number for a notebook that packs a six-cell battery, standard voltage processor, and Nvidia integrated graphics. If ASUS had used Intel integrated graphics instead of Nvidia, the battery life would likely have been a bit longer.
The K40IN comes with Windows Vista Home Premium 32-bit and a ton of pre-loaded utilities. There are at least ten utilities installed – managers for this, monitors for that, and so on. Many of them are startup items which increase log-on time. If ASUS could consolidate all of them into a central control panel then this would not be such an issue. The sheer number of them at present is unnecessary.
The K40IN has good build quality, a pleasing keyboard and screen, and gets over four and a half hours of battery life. Unfortunately the K40IN's value proposition is questionable. It lacks an HDMI port and is priced $100-$150 more than competitors with the same specifications minus the Nvidia graphics. The Nvidia graphics are a puzzling choice for the K40IN; they are not powerful enough to play modern games and consume more power than Intel graphics. The only advantage the K40IN has over its competitors is better warranty coverage. Overall we like the K40IN but are hard-pressed to recommend it for the stated reasons.

In terms of design, this laptop is excellent. It is not very expensive. The graphics are mind blowing. Typing is very comfortable, the keyboard is quite spacious. Battery life is very disappointing. For more details refer asus k40
