The Dell Inspiron 1720 is a 17" desktop replacement targeted towards younger consumers, most of whom are in school. This notebook competes against such notebooks as the HP dv9500t and Toshiba P200/P205.

Build and Design

Gone are the white bumpers of old, replaced with a solid shimmering silver paint, giving the body of the Dell 1720 a much cleaner and refined look. The body still allows some user configuration with its custom top cover paint options, including jet black, alpine white, espresso brown, ruby red, midnight blue, spring green, flamingo pink, and sunshine yellow. The high level of personalization can even go as far as a color matched Logitech mouse as an added $29 option during checkout.

The cleaner look and feel is matched with an even stronger and more durable chassis. During testing no plastic creaks or squeaks could be heard, with flex only apparent in the plastic painted screen cover. The entire bottom shell is a metal alloy which gives the laptop a strong footprint on your desk, and is gives enough strength to resist bending if you hold the laptop by the edge of the palm rest walking around the room. The only downside to the chassis was the metal HD bay cover had some movement, and would make clacking sound if tapped with your finger, or placed on an uneven desk. Overlooking that fact, the underbody is strong enough to hurt your knuckles if you try to punch it without giving up as much as a millimeter of flex in the process.

One concern worth mentioning with the custom paint process is long term durability. The review model we received had a paint defect out of the box on the upper right hand cover of the LCD cover. The rubbery texture paint was already peeling; exposing the glossy espresso brown paint underneath. Since this peeling was visible straight out of the box, long-term day to day use inside various cases or backpacks might show more extreme peeling. Hopefully the paint issue was fixed in production, as our review model has an early May build date.

The glossy WUXGA (1920×1200) screen on the Dell 1720 is absolutely beautiful.  No dead pixels were found during testing, and backlight bleed while noticed on some dark screens was minimal. Colors were vibrant as with many glossy screens, and wide viewing angles made the screen look sharp even at odd contorted angles. Backlight adjustment was very broad, allowing me to adjust low enough for darker room settings, and bright enough to still be readable in sunlight or a bright office. I had the adjustment sitting around the 80 percent mark or two notches down from max level for most of my testing.

Protection for the screen through the rear cover prevented any rippling when you press in the cover. While the plastic section did have more flex than the alloy main body, it was still better than most. The release latch was kind of tricky, and compared to most latches required too much effort to release. Its smaller slick surface needed a fingernail to catch it to release the latch.

The speakers on the 1720 were better than average for most laptops, comparable to speakers found on most midrange televisions. While lower bass was lacking, volume levels were quite loud, and distortion at peak levels was not present. Combined with the 17" display, it would not be hard at all to entertain a small group of friends in a dorm room with the laptop by itself.

Keyboard and Touchpad

The keyboard and palm rest structure matches the strength of the bottom panel of this laptop. Pressing down very firmly, the keyboard flexes less than my T60 Thinkpad. The palm rest is just as firm, supporting my wrists or elbows pressing down with barely a hint of flex.

The keyboard was very comfortable to type on, and gave just the right amount of response for each key press. Throw length was about even with my ThinkPad, with just a bit less clicking sound. The keyboard layout was not cramped at all, and the control key was in the correct (outmost) position on the left-hand side.

The touchpad I felt could be improved. It exhibited a slight delay when starting each time, almost what is seen with some wireless mice, and it also had a hint of lag. The size of the touchpad surface was large enough for comfortable control, and the surface texture had a smooth matte feel. The two touchpad buttons spanned the full length of the touchpad, and each had a responsive click when pressed. One thing I would have liked is a third touchpad button to allow easier control of tabs during web browsing.

Performance and Benchmarks

The Dell 1720 as configured has more than enough speed and storage space to handle most users needs. The Intel T7500 and nVidia 8600M GT combined really make this laptop an excellent performer, for both multimedia uses and gaming. Below are benchmarks to give you an idea of how this laptop might compare up against other rivals in the same category.

Heat and Noise

Coping with heat under stress is one task that this laptop shrugs off with ease. Using two instances of Prime95, each stressing an individual core, the processor went up to 75C after 40 minutes. Outside temps were barely fazed though, even with internal parts scorching hot. With a room temperature of 24C, the palm rest was 27C on the right side, and 29C on the left side. Keyboard temperature was between 30-33C going right to left. Air coming out of the heatsink grill came out at around 46C. Underside temps were into "warm blanket" range of 40-42C, so wearing pants while gaming intensively should be recommended. After letting the laptop cool down for 20 minutes, the keyboard and palm rest evened out at 29-30C with the bottom peaking at 36C under the heatsink area.

The fan noise was rarely loud enough to be heard in a quiet room unless the notebook was under extreme stress such as benchmarking or serious gaming.

Input and Output ports

Port selection was not a problem, although I would have enjoyed seeing a DVI or HDMI port included since there is more than enough free space around the perimeter of this 17" notebook. Going around the notebook, we find the following ports

Left: Kensington lock slot, expresscard slot, WIFI on/off/search switch (view large image)

Front: Media access and volume controls (view large image)

Right: Headphone/Mic, Firewire, VGA, LAN, two USB (view large image)

Rear: S-video, two USB, Power connector, 56k modem, one USB (view large image)


This laptop came with Windows Vista Home Premium preinstalled, as well as other smaller applications included through Dell. The most notable addition being the Norton Internet Security package which I uninstalled from the system during review to speed it up.  Another item unique to Dell is the "Dell QuickSafe" online storage system which comes included free for one year. This gives a user 3GB of online storage space for backing up documents, pictures, or other information to an outside source incase of system failure (or losing your laptop). The user then selects the folders they want backed up, what interval to have it pulled off the system, and let the software do the magic behind the scenes.


Under normal web browsing use the 9-cell battery performed quite well, pushing out 3 hours and 12 minutes of life before going into hibernation mode at two percent. Screen brightness was two notches below max, or about 80 percent, and other items were set to Vista’s balanced power plan. This gives more than enough time for taking notes (surfing the web) during a couple of classes throughout the day away from an outlet.


This Dell 17" laptop is a great performer and extremely well built laptop structurally. It seems to be built well enough to be thrown around in day to day use, and hold up throughout an entire college career. It will roll with the punches, and probably hurt your fist in the process. The only problems I found which don’t relate directly to the function of the laptop are the peeling paint, which should hopefully be worked out as production goes on in the upcoming months. Dell has mentioned paint quality problems with this new design, and how they were working to improve the painting process. Counting out that problem this is a great laptop, and I hope Dell continues on this trend of well built, affordable machines.


  • Very tough structure and underbody.
  • Strong gaming performance with the 8600M GT
  • Excellent battery life for a 17" notebook
  • Bright and Vivid LCD with excellent viewing angles


  • Paint defects out of the box
  • HD Bay cover has some play, making loud clacking noises
  • No plaid paint option … they offer every other color after all.
