Review Toshiba Satellite T135D

The Toshiba Satellite T135 series is a popular 13-inch thin-and-light notebook available in a variety of configurations. We previously reviewed the T135 with Intel inside, but what about the T135D with the latest AMD dual-core processors and ATI graphics? Does the AMD-based T135D offer more than the Intel-based T135 for $100 less? We took a closer look to find out.

Build and Design
The Toshiba Satellite T135-series notebooks are stylish ultraportables that look like previous 13-inch Toshiba notebooks, but in a much thinner and lighter chassis. Toshiba keeps the profile only a fraction of an inch thicker than the USB ports on the side of the notebook, though this is done in large part by cutting out things like an ExpressCard slot and optical drive. For the average user this notebook has all the advantages of a standard computer--a high resolution display, a full-size keyboard and a dual-core processor--but none of the bulk. The black color scheme on our T135D looks nice, although the red exterior of the Intel-based T135 was a nice change of pace. Toshiba offers multiple color schemes for this notebook, so if you don't think black is beautiful then there are other options available for you to purchase.

Build quality for both the Intel and AMD versions of the T135-series notebooks is very nice despite the very thin chassis. In fact, the exterior of the T135D is identical to the exerior of the T135 except for the AMD sticker on the palmrest. Unlike some of the thin-and-light notebooks we've reviewed from other companies, flex and plastic squeaks are kept to a minimum on the T135D, and a metal plate over the hard drive helps keep the vital components safe. The screen cover feels durable as well, although it the screen lid does suffer from some minor flex next to the hinges. In any case, the glossy exterior of the T135D should hold up to typical use and abuse inside a school backpack or an office briefcase. The glossy finish on the body withstands most scratches, but you'll need to constantly clean off fingerprints and smudges if you want to keep your laptop looking new. The imprinted pattern on the lid and palmrests does a good job of hiding small fingerprints, but sooner or later you will need to find a microfiber cloth.

If you're interested in upgrading the internal components on your T135D you'll be happy to learn that the system memory and hard drive are easy to locate beneath a pair of cover plates on the bottom of the notebook. Unfortunately, Toshiba has once again decided to secure the hard drive bay with Torx screws rather than standard Phillips head screws. This means that you'll need to use a set of precision screwdriver bits with Torx adapters if you want to remove the hard drive. This isn't a major problem, but it is something of an inconvenience for do-it-yourself PC owners. The cover panel for the memory slots uses standard Phillips screws, so that will be an easier upgrade. No warranty void if removed stickers were found anywhere, so it should be safe to swap out basic components without risking your warranty coverage.

Screen and Speakers
The 13.3" LED-backlit screen on the T135D appears to be identical to the display panel used on the T135. Colors appear overly saturated (not always a bad thing, but a matter of personal preference) and the contrast ratio looks below average with fairly light black levels. Horizontal viewing angles are good out to at least 45 degrees to either side before you start to notice color distortion. Vertical viewing angles are below average as the display becomes over exposed or colors begin inverting after moving the screen 15 degrees forward or back. Overall screen brightness is good enough for indoor usage under bright office lights or in the shade outdoors. The glossy screen makes reflections something of a problem if you try to use the screen outdoors under direct sunlight.

Speaker quality is below average as the maximum volume output isn't loud enough to fill a large meeting room withn clear sound. The maximum volume setting on this notebook sounds more like what we expect when we set multimedia notebooks to 50 percent volume. Part of the problem is the speaker location on the bottom front edge of the notebook ... which means sound is directed down and away from you rather than up toward your ears. The other issue is the small size of the speaker drivers themselves. Toshiba simply didn't put impressive speakers into this notebook. If this is your only PC for listening to your music library then I suggest purchasing a good set of headphones.

Keyboard and Touchpad
Once again, the full-size keyboard on the T135D is identical to the T135 and we don't have much new information to share with you. The keyboard is comfortable for typing and offers excellent support even under very strong typing pressure. The palmrests are just about perfect for average adult male hands as they support the wrists without causing additional stress points while typing. The individual keys have a springy, responsive action and each key has a flat surface similar to a Chiclet-style keyboard without the additional space between each key. Typing noise is minimal, with no loud "click clack" noises while typing. Consumers who are thinking about buying this notebook for typing long documents or notes during class should have no problems with this keyboard

The Synaptics touchpad was once again a slight disappointment in that it had a very slow refresh rate. Replacing the drivers with the latest ones offered on the Synaptics website didn't improve this issue, so our best guess is that the slow refresh issue has something to do with the touchpad surface/hardware itself. That said, when we uninstalled the drivers the touchpad felt a bit more responsive, so this may indeed be a bug in the Synaptics drivers. We still recommend using the Synaptics drivers since they allow you to use those helpful touchpad features like scrolling or correcting the position of your touchpad/scroll zones. Regardless of the slow refresh issue on the touchpad, the touchpad surface itself is a joy to use. Most of our lab testers agreed that you can easily glide your fingertip across the touchpad surface. The touchpad buttons are made of a reflective silver plastic and don't offer much in the way of comfort. The individual key press is rather shallow and you have to press the left and right buttons along the outside edge ... since the touchpad buttons don't always work if you press near the middle.

Ports and Features
Port selection is fairly good when compared to ultraportable notebooks, but we're starting to get worried about the lack of either an ExpressCard slot or eSATA port on 13-inch and larger notebooks. USB is fine for smaller notebooks, but larger notebooks need to offer a few more options in terms of ports. The T135D includes three USB ports, VGA and HDMI-out, LAN, audio jacks, and a Kensington Lock slot. Expansion slots include just the 6-in-1 SDHC-compatible card reader.

Right: 6-in-1 card slot, audio jacks, two USB, LAN, AC power

Performance and Benchmarks
We found the Intel SU4100 CULV processor and Intel integrated graphics in the T135 to offer reasonable performance, but we were particularly excited to see how the T135D would perform with an AMD dual-core processor and ATI integrated graphics. The short answer is that the 1.6GHz AMD Turion Neo X2 processor performs a little faster than the Intel offering, and the ATI graphics clearly perform better when it comes to basic gaming such as World of Warcraft or older first-person shooter games.

In terms of day-to-day activities it's fair to say that most consumers won't notice much (if any) performance difference between the T135 and T135D. That fact alone probably means most consumers should consider the AMD-based T135D since it's $100 cheaper than the Intel-based T135. However, we did stumble onto some issues in terms of battery life (more on that later in the review). HD video playback for both 720P and 1080P content was flawless, but unlike the Intel CULV solution, the T135D with AMD processor and ATI graphics didn't stress the CPU as much when playing HD video. The only test that we ran in our lab that suggested the AMD processorm might not perform as well or better than the Intel processor was the PCMark05 synthetic benchmark, but we've found that this benchmark doesn't always reflect real-world experience. Bottom line, the AMD-based T135D should offer every bit as much performance as the Intel-based T135 ... for $100 less.

Heat and Noise
Noise levels were great for normal daily use. The default fan speed is always on at a low setting, pushing hot air away from the CPU and out of the notebook. The fan doesn't get much louder even if you stress the system with a game or video encoding. Unfortunately, the quiet fan means you get higher than normal case temperatures when the notebook is left on for more than 30 minutes. The external case temperatures on the T135D are roughly 10+ degrees hotter than what we saw on the T135 next to the CPU and the RAM. This makes the T135D less "lap friendly" than the T135 and you'll probably want to keep it on an airline tray table or a hotel desk when working on the road. All temperatures shown below are listed in degrees Fahrenheit.

Battery Life
Although the AMD-based T135D offered as much (or more) performance than the Intel-based T135 in day-to-day tasks, the AMD processor simply didn't deliver as much in the way of battery life. In our battery test with the screen brightness set to 70%, wireless active, and Windows 7 set to the "balanced" profile the system managed 5 hours and 48 minutes before shutdown. This is more than enough battery life for most consumers who just need a laptop for a few hours of web browsing at a coffee shop, but it is obviously less than the 8 hours and 18 minutes of battery life we saw with the Intel-based Satellite T135.

Granted, it wasn't too long ago that we used to praise any notebook that delivered more than 3 hours of battery life. However, 5+ hours just isn't quite as impressive in a world with notebooks and netbooks that can run for 8 or more hour on one battery charge.

Conclusion
At the end of the day Toshiba left consumers with an interesting pair of options for a thin-and-light notebook with a 13-inch display. The Intel-based Satellite T135 offers good performance, a nice notebook design, and great battery life for $700. On the other hand, the AMD-based T135D delivers better performance with day-to-day tasks and an identical design for only $600. Sure, you "only" get five and a half hours of battery life with the T135D and there's a hot spot next to the RAM and CPU, but $100 goes a long way when you're trying to save money.

The Toshiba Satellite T135D is a solid notebook that offers a lot for a modest price. It's not perfect, but if you can learn to live with its flaws then you can save $100.

Pros:

• Excellent performance
• Great price
• Good keyboard

Cons:

• Exterior gets hot
• Average battery life
• Glossy plastics

Review Lenovo ThinkPad W510

The ThinkPad W510 is Lenovo’s 15.6-inch workstation notebook offering an Intel Core i7 processor and NVIDIA Quadro FX 880M graphics. New to this year’s model is an optional 1080P multi-touch screen with a 95% color gamut and built-in huey PRO color calibration system. In this review, we take an in-depth look at the ThinkPad W510 to gauge its performance as a mobile workstation.

Our Lenovo ThinkPad W510 Specifications:

• 15.6-inch multi-touch FHD (1920 x 1080) LED Backlit 95% Gamut (matte finish)
• Windows 7 Professional (64bit)
• Intel Core i7-920XM (2GHz, 8MB Cache)
• 8GB DDR3 RAM (4GB + 4GB)
• 500GB Seagate 7200.4 HDD (7200rpm)
• Intel 6300 802.11AGN, Bluetooth, Gobi 2000 WWAN
• NVIDIA Quadro FX 880M with 1GB DDR3
• 94Wh 9-cell, 135W 20V AC adapter
• Dimensions: 14.68" x 9.65" x 1.35-1.57"
• Weight: 7.2 pounds
• Retail Price: $2,059 Starting (Exact configuration price unavailable)

Build and Design
Compared to the previous generation 15-inch ThinkPad, Lenovo has made many design tweaks with the W510. For starters, the screen hinges are the same width, whereas before the hinge on the right side was much narrower. Another change is when the ThinkPad is open; the screen itself is centered with equal width bezels on both sides. The uneven screen was found to be annoying by some ThinkPad users and it is nice to see Lenovo finally address that odd design element. As a whole, Lenovo has done a great job of keeping the newer ThinkPad models looking just like previous generations. Some changes have been made to update the touchpad, ThinkPad logo, and port layout over the years but anyone off the street would be able to instantly recognize the brand.

Build quality is very good on the Lenovo ThinkPad W510. Out of the box, this model has a stronger feel to it than most of the smaller ThinkPad models and is fairly hefty. Our model weighed in at just about 7 pounds and is built like a tank. The newer palmrest and keyboard design is solid as a rock with a strong support structure underneath the plastic. Even with a strong grip or a lot of downward force, we saw minimal flex around the palmrest and keyboard. Following with its “overbuilt” (in a good way) trend, the screen hinges are strong enough that it required two hands to open the notebook and even to tilt back the screen once the lid was opened. When fully open, the screen did not have loose wobble or other problems staying firmly positioned. Considering this model offers a multi-touch screen, we found its overbuilt quality to be essential because the entire panel might otherwise push back when pressing on the touchscreen.

The easy access to all serviceable components might appeal to W510 users looking to upgrade. The bottom of the notebook has two covers which houses the hard drive and RAM slots three and four. Removing two screws lets you pop off the keyboard, giving you access to the wireless cards and RAM slots one and two. One point I want to make clear is even with models configured with fewer than four total sticks of memory, Lenovo still includes two open memory slots. We have seen models like the HP EliteBook 8540p that have the spots on the motherboard for two additional memory slots, but don’t solder them in place if the notebook isn’t configured with the additional memory from the factory.

Screen and Speakers
Lenovo includes a brand new multi-touch screen option on the ThinkPad W510. This panel has a resolution of 1920x1080, a high color gamut of 95%, and bright LED backlighting. We measured a peak brightness of 215cd/m2 with the backlight turned to 100%, which is more than bright enough to be fully visible in bright office conditions. Compared to past ThinkPad screens, the W510 ranks just under the X200 Tablet we reviewed in terms of panel quality. Color saturation was well above average, making this screen great for designers but unpleasant for the average user. If you are accustomed to viewing a normal LCD which has a color gamut between 70-80%, viewing this screen will look pretty strange with most colors being over saturated. This isn’t a problem with the screen itself; it’s just an attribute of a high color gamut display. Viewing angles were average with most colors starting to distort or invert when tilted 15 to 20 degrees forward or backward. The high color gamut seems to extend the viewing range slightly, but only because colors still look “normal” even though they have lost most of their potency. Horizontal viewing angles were good to about 70 degrees before the touchscreen layer started to block the light output.

The multi-touch surface was easy to use and responded to a light touch. It supported two-finger inputs like scrolling and zooming. Compared to other touchscreen surfaces, the W510 had only a slightly hazy appearance and didn’t seem to distort the LCD beneath it unless you were viewing the screen from a steep angle.

Another cool screen feature of the W510 is a huey PRO color calibration system. With the screen intended for graphic designers and image editors, one important area is the screen’s color accuracy. The color calibration software helps to correct any color shift as a result of the backlight, color changes over time, or simple screen aging. We actually found that it helped take the over-saturated edge of the screen and helped bring a sense of balance back to the system. Pre-calibration whites had a mild red tint and after calibration they had a cooler look and closer to the normal spectrum. If you opt for the nicer screen, it’s well worth an extra $70 to get the color calibrator if you’re picky about your screen’s appearance.

Speaker quality is average compared to other business notebooks but rates below mainstream consumer notebooks. While the speaker grills might suggest large speakers located under the trim they are in fact very tiny speakers. Peak volume levels are fine for filling a small to medium-size room. Bass and midrange is weak, but this is common for notebooks in this category.

Keyboard and Touchpad
The ThinkPad W510’s keyboard is comfortable to type on and easily lives up to the well-known reputation of all ThinkPad keyboards. It has excellent support showing little flex even under strong pressure. Tactile feedback is great with a precise hinge mechanism and secure key top that doesn’t exhibit any wiggle. The keyboard is the newest design seen first on the T400s and now the T410. The layout changes the position of some of the function keys and adds a row of quick-access sound keys to change the volume level, and mute the speakers and microphones. Another subtle change is a decrease in spacing between each key that supposedly reduces the chance of crumbs getting under them.

The W510 offers a spacious Synaptics touchpad with multi-touch capabilities. Compared to past models, the touchpad surface is textured to reduce friction and prevent your finger from sticking as you slide it side to side. After using the older matte plastic finish version for so long, it is hard to choose my preferred model. Each has its advantages, but only the newer model is multi-touch enabled. The touchpad buttons are easy to use since they are located right along the sloped edge of the palmrest. Feedback is great with a soft touch and a long throw.

Ports and Features
The W510 offers a wide range of ports and features. The port selection includes two SuperSpeed USB3 ports, one USB 2.0 port, one eSATA/USB combo port, FireWire 400, LAN, modem, VGA and DisplayPort-out, and a combo headphone/microphone port. The notebook also features an ExpressCard/34 slot, a SDHC-card reader, and a Blu-ray player.

Right: ExpressCard/34, SDHC-card reader, optical drive, LAN, Kensington Lock slot

Performance and Benchmarks
The Lenovo ThinkPad W510 is a mobile workstation that offers a similar performance of most desktops. Our particular configuration included 8GB of DDR3 memory, an Intel Core i7-920XM Extreme Edition processor, and an NVIDIA Quadro 880M FX graphics card. System performance was excellent in every one of our lab situations, and the 920XM barely broke a sweat. Compared to past systems, this configuration did seem to give us benchmark results lower than other notebook components. It’s a result we’ve seen before with past workstation models that have drivers fine tuned for CAD and rendering applications, but not video games.

The only problem we came across was when we tried to use a power brick lower than the 135w model that was supplied. When the notebook detects you have anything less than the stock power adapter connected it severely limits the notebook’s performance. In this situation, it ran about three times slower than it did running on battery power. wPrime in this mode took more than 70 seconds to complete and the PCMark05 returned a score of 2,000. We bring this up because long-time Lenovo users might have a collection of power bricks from past notebooks. Lenovo hasn’t changed the adapter since the T60, which is great for compatibility. This also makes it convenient to use at home, work or during travel trips without bringing the brick with you. However the W510, or at least our configuration of it, will not come close to the level of performance when using the small power adapter.

Heat and Noise
Under normal conditions, the W510’s the heat and noise levels are fairly modest with low fan speeds and comfortable case temperatures. When the system is sitting at or near idle, the case fan cycles on and off at a near whisper level. When the system is under stress -- like while running SPECviewperf for more than 15 minutes -- temperature and noise levels rose considerably. During the middle of the workstation benchmark run, we measured a peak exhaust temperature of 136 F as it was drawing 111 watts from the wall. Case temperatures during this time jumped 10 to 15 degrees, placing the system well into an uncomfortable range. However, we didn’t have a problem with the temperature rise because most users in this situation would be using the portable workstation on a desk instead of their lap.

Battery Life
This particular ThinkPad was a bit of a power hog throughout most of our tests. On the AC-power side, the notebook demands the larger 135w power supply when turned on or it locks the system into a low-power mode which drastically reduces performance. When running off of a battery, the system draws between 16 to 17 watts of power, which didn’t help its battery test results. With the screen brightness turned to 70%, wireless active, and Windows 7 set to a balanced profile, the ThinkPad W510 stayed on for four hours and 30 minutes before turning off. This time could be attributed to the Intel Core i7 Extreme Edition processor and the NVIDIA Quadro FX 880M graphics card.

Conclusion
The Lenovo ThinkPad W510 offers great performance, excellent build quality, and a beautiful 1080P multi-touch display with a 95% color gamut. The notebook offers a wide range of high-end features including four DDR3 memory slots to allow a total of 16GB of RAM, an optional Intel Core i7-920XM Extreme Edition processor, an optional multi-touch 1080P display, and an optional built-in color calibrator. For the average user, most of these features are excessive, but if you demand the highest performance from a mobile workstation, the ThinkPad W510 has you covered.

Pros:

• Beautiful FHD multi-touch display
• Great build quality
• Excellent performance

Cons:

• Pricey when you add the options
