HP Pavilion dm3t Review

The Pavilion dm3 is a CULV thin and light notebook series from HP that includes both the AMD-based dm3z and Intel-based dm3t. This notebook packs a 13.3-inch screen, optional integrated WWAN, an optional matching external optical drive, and a wide range of processor options. In this review, we take a look at the Pavilion dm3t powered by an Intel SU7300 CULV processor,inspiron 1525 battery and includes 3GB of DDR3 memory and Intel X4500 integrated graphics.Lenovo/IBM ThinkPad T60


Build and Design

The HP Pavilion dm3t offers an attractive and durable brushed metal finish on its screen cover that resists smudges and scratches.inspiron 6400 battery The perimeter-trim is chromed plastic to accent the gunmetal-gray brushed finish that extends inside the notebook for the palmrest and keyboard surround.Lenovo/IBM ThinkPad X60 The screen trim is a glossy black,xps m1330 battery which blends in with the LCD when the screen is off. The bottom of the notebook is painted with a matte-black finish.


Build quality is above average with the brushed metal finish helping to give some strength to the top of the notebook.dell d620 battery The screen only has some flex under moderate pressure and the cover protects the LCD from most impacts.HP 510 The quality of the materials used is above average on most areas of the notebook; although the chromed plastic might be at risk to chipping over time if you are not careful with transporting it.Acer Aspire 4710 The one area that stood out to us as needing improvement is the touchpad finish, which out of the box had some mild scuffing.HP Pavilion DV9000 HP uses a polished-matte finish that doesn't seem to hold up to mild abrasion as nicely as their older painted glossy touchpads. The bottom cover was a big surprise, since unlike other consumer notebooks that only use plastic bottom covers,Sony VGP-BPS8A HP goes all out with a durable alloy body that adds a nice look and feel when holding the notebook.


Users looking to upgrade their dm3-series notebook will find it easy to access user-serviceable components.Sony VGP-BPS8 The bottom has three compartments, one of which is the battery.Sony VGP-BPS13A/B The two that contain serviceable parts are clearly labeled with symbols showing what parts are underneath. One bay houses the hard drive and WWAN-slot while the other has the system memory and Wi-Fi card. Our model,Sony VGP-BPS9 which didn't include WWAN, still came with the slot soldered in place. No antennas were visible, but at least an upgrade would be possible down the road.


Screen and Speakers

The screen on the dm3-series is a 13.3-inch LED-backlit panel with above average color and contrast.Sony VGP-BPS8B Colors from the screen are bright and vibrant with a cooler or blue hue.Sony VGP-BPS9/B Screen brightness is more the adequate for brightly lit rooms with a peak brightness measured at 212nit. We found screen brightness set at 70% was perfect for viewing indoors.Sony VGP-BPS10 Outdoor viewing with the glossy panel would only be possible in a shaded area away from sun glare. Viewing angles were average with colors starting to invert or wash out when the screen is tilted 15-20 degrees forward or back.Sony VGP-BPS9/S Horizontal viewing angles were better with the screen staying visible to about 60-degrees off center where it started to dim noticeably.


The speakers on the dm3-series are lap-firing,Acer UM08B71 located near the front edge of the palmrest. Sound quality is above average for a notebook this size with clear upper-midrange and high notes. Low frequency audio is still lacking,apple a1060 battery but it is hard to get this from even larger notebooks unless you have a dedicated subwoofer.


Keyboard and Touchpad

The keyboard is an island-style variant that is very similar to the look and feel of most Apple MacBooks.apple a1045 battery The keys are painted with a semi-gloss black paint and feel very solid to the fingertips. The lettering is very bright and visible even in dark lighting. Key movement is precise with little wobble with side to side movement.Dell inspiron 1525 battery Individual key presses are smooth and require very little pressure to fully trigger. If you like the look and feel of the Chiclet-style keyboards, you will be impressed with the Pavilion dm3t.


The touchpad is a glossy ALPS model with some support for multitouch gestures.Dell latitude e6400 battery The touchpad on average is responsive with very little lag. On a rare occasion the touchpad did become entirely unresponsive and required a reboot before it started to work again.Toshiba PA3399U-1BAS It is unclear if this was a driver conflict or a problem with the touchpad itself. The touchpad buttons are easy to press with the side of your thumb and give off a small click when pressed.Acer BTP-60A1 They have shallow feedback and require moderate pressure to activate.


Ports and Features

Port selection on the Pavilion dm3t was great with HP making use of nearly all usable space around the perimeter of the notebook.hp pavilion dv6000 battery The system featured four USB 2.0 ports, HDMI and VGA-out, LAN,Fujitsu lifebook s6510 battery audio jacks and a Kensington lock slot. Other features included a SDHC-card slot and wireless-on/off switch. One unique item on the dm3-series that caused a bit of confusion when it was first taken out of the box was the power button's location. It is located on the right side next to the wireless-on/off button as a small slider-switch.
