Review HP Envy 13

Last year, HP claimed to "redefine the premium notebook PC" when the company unveiled the new HP Envy 13. This 13-inch notebook offers high-performance, power-efficient processors, ATI switchable graphics, lightweight aluminum and magnesium construction, and features a bright screen with amazing color depth for exceptional picture viewing and video playback. On paper, the Envy 13 promises to be everything you want in a laptop. Keep reading to find out if this premium notebook is worth its premium price tag.

Our HP Envy 13 Specifications:

  • Windows 7 Home Premium (64-bit)
  • Intel Core 2 Duo Processor SL9600 (2.13GHz, 6M Cache, 1066 MHz FSB)
  • 3GB DDR3 SDRAM (1066MHz)
  • 250GB 5400RPM SATA hard drive
  • 13.3-inch diagonal High Definition LED HP Radiance Infinity Widescreen Display (1366x768)
  • ATI Mobility Radeon HD 4330 Graphics (512MB) with Intel X4500M integrated switchable graphics
  • External Slot Blu-Ray ROM with SuperMulti DVD+/-R/RW Double Layer with 2 USB Ports
  • Intel Wireless-N Card with Bluetooth
  • Dimensions: 12.59"(W) x 8.46"(D) x 0.8"(H)
  • Weight: 3.75 pounds (not including weight of AC adapter).
  • 4-cell 41Wh battery
  • One-year standard warranty
  • MSRP: $1,924.99

Build and Design
The Envy 13 marks a significant design departure for HP. Gone is the glossy HP Imprint finish that was common to its Pavilion line, and plastic has given way to aluminum and magnesium alloy. The simple magnesium lid doesn't feature any kind of eye-catching design, but we appreciate the emphasis on function over form. This is one of the most durable lids we've seen on a 13-inch consumer notebook and should easily withstand any use and abuse from most owners. We applied significant force to make the lid flex, which means the screen should be well-protected inside your laptop bag or backpack.


Build quality remains very good thanks to a solid chassis and durable components throughout. The etched-metal palmrest provides an interesting combination of style and support. The magnesium palmrests don't flex like typical plastic palmrests and the etched pattern is a subtle way to add a splash of creativity to a typically boring area of the notebook. I suspect the recessed etching might collect dust and dirt over time, but the etching is shallow enough that you can probably clean it with a microfiber cloth.


People who like to upgrade their computers on their own by adding extra RAM, a new hard drive, or other aftermarket features will be in for a rude awakening with the Envy 13. HP built this notebook with an emphasis on the thin form factor and clean lines. There aren't easy-access panels on the bottom of the notebook or quick release tabs for the keyboard. Getting inside the Envy 13 isn't a task for the faint of heart. If you decide to upgrade it yourself, you'll need to remove four rubber feet from the bottom of the notebook in order to expose recessed screws, then remove the battery and several additonal screws before finally removing the entire bottom plate. Given the complexity of disassembly, you're probably better off purchasing upgrades when you buy the notebook rather than trying it on your own.


The ENVY 13 and 15 are packaged in new "green" yet stylish paper carton boxes using minimal ink. To further HP's environmentally-friendly goals, the only paperwork included in the packaging is a simplified setup poster. All additional documentation - from the user manual to the warranty guides - are contained on a SD card in the box. The power adapter, VGA display adapter and optional external Blu-ray drive fit neatly inside storage spaces beneath the notebook.

Screen and Speakers
The 13.3-inch "HP Radiance" display is roughly twice as bright as other notebook displays of the same size – 410 nit brightness – and this helps compensate for the glossy surface covering the screen
. It also allows you to cleary see the screen even under direct sunlight. This LED-backlit display offers 82 percent color gamut (versus the standard 45-60 percent on other notebooks), so photos have more intense color saturation and video "pops" off the screen. Of course, if you're a photography enthusiast you might want to tone down the colors on this display since they are a bit too rich compared to natural colors. Viewing angles are average, though at first glance, the screen looks better since the intense color depth masks the typical signs of color shift and inversion at steep viewing angles.

The built-in stereo speakers carry the "Beats Audio by Dr. Dre" branding which suggests a premium listening experience. In our test lab, the results weren't as impressive as the "Beats" brand implies. The speakers produce clear sound with plenty of volume but bass is lacking and the overall sound quality is rather tinny; akin to listening to music from inside an aluminum can. Headphones are the best option to enjoy music and movies from the notebook. Another alternative is using the HDMI-out to pass digital audio to a home stereo.

Keyboard and Touchpad
The full-size island-style or "Chiclet" keyboard is a welcome change from HP's previous keyboards and provides excellent key spacing and support. Most of our editors agree that the 13-inch form-factor is a perfect compromise between size and user comfort when typing. Too small, and the palmrest won't support your wrists. Any bigger, and the notebook ceases to be travel-friendly. Key action is smooth and quiet with a mild click emitted when you fully press a key. Key wiggle is minimal and individual key depth or "throw" is perfect. We didn't notice any keyboard flex on the underlying support struicture even when we pressed forcefully on the keys. In short, the
Envy 13 keyboard is among the best we've used on a 13-inch notebook.

The Envy 13 offers a large and spacious Synaptics touchpad with integrated touchpad buttons. HP calls this a "Clickpad" but that name feels odd to me. When it comes to size, this is one of the nicest touchpads I've used on a 13-inch notebook - with a few exceptions. If you are someone who rests your thumb on a touchpad button and moves the cursor with one of your other fingers, you will need to learn to use the touchpad in a completely different way. The cursor will often jump from one finger to another when the thumb is resting since the entire touchpad surface is being used. You can get past this dilemma by using one finger to move the cursor and then use the "tap to click" setting to click on icons. The touchpad is just too sensitive for two fingers.


Ports and Features

Port selection is disappointing on the Envy 13. You get a SD card slot, two USB 2.0 ports, HDMI out and a combo audio jack. This is simply depressing since most 11-inch notebooks offer more. Frankly, given the cost of the notebook and the amount of unused space around the edges, HP could at least add one more USB port as well as FireWire or eSATA. On a more positive note there are three large heat vents on the sides and back, so at least overheating shouldn't be a problem.


Performance and Benchmarks
System performance with the Intel Core 2 Duo SL9600 processor is average and not particularly impressive considering the price. The dual-core processor is more than capable of handling multiple applications with minimal lag, but if you're going to pay almost $2,000 for a notebook, you want serious performance. The SL9600 underperforms against the older Core 2 Duo P8400 used in last year's 13-inch MacBook Pro. That said, the Envy 13 still offers noticeably faster application switching and file conversion than cheaper notebooks using the Intel CULV class processors.

The Envy 13's graphics solution is more interesting than the processor. The ATI Mobility Radeon HD 4330 Graphics card with 512MB of dedicated memory and Intel X4500M integrated switchable graphics means the Envy 13 offers the best of both worlds: You get performance for HD video and gameplay and extreme battery life when on the road. HP set up the Envy 13 so that the ATI discrete graphics are always enabled when the power adapter is plugged in and the Intel integrated graphis are always used when it's running on battery power. You can switch these default graphics settings using the display menu in Windows, but we would have liked to see a keyboard shortcut to quickly force the laptop into discrete or intergrated graphics modes.

Heat and Noise
System temperatures stayed within normal ranges with the dual-core processor. The hard drive cavity was noticeably warm, but the temperature wasn't uncomfortable. Noise levels were about average for a computer of this size, but the fan runs at a constant low hum even when the notebook is running on battery power. If you need absolute silence in your workspace then the Envy 13 might not be an attractive option. If you don't mind subtle white noise in your daily routine, then you might not even notice the fan when it's running on battery.

Battery Life
Battery life with the 41Wh Li-Ion battery and the L9600 processor is good for a 13-inch notebook running on integrated graphics. In our test with the screen brightness set to 70%, Windows 7 set to the "HP Recommended" power profile, and wireless active, the system stayed on for 6 hours and 55 minutes before going into standby mode. Power consumption during this test floated around 6 watts. When we plugged the external Blu-ray drive
in, the battery life dropped to just under three hours while watching DVDs. HP also offers an optional second 6-cell battery "slice" that connects to the bottom of the Envy 13 and covers the entire bottom surface of the laptop. Although this essentially doubles the thickness of the notebook, HP claims it more than doubles the system's running time.

Conclusion
Without a doubt, the Envy 13 is among the most innovative consumer notebooks that HP has ever created. However, it still feels like HP engineers spent too much time and effort trying to make a "MacBook alternative" and missed the mark completely. Yes, the Envy 13 offers exceptional build quality, a fantastic keyboard, good battery life and a stylish design, but it lacks a number of ports and is more expensive than a 13-inch MacBook Pro.

The Envy 13 is a nice laptop, but few of our editors would rush to buy one for its starting price of $1,500. Here's some advice for HP and other PC manufacturers: If you want to make a MacBook subsitute, don't try to copy the MacBook. There are many PCs out there that are more compelling than Macs in terms of design, features, and price, so think outside the box - or, at least, outside the Apple.

Pros:

  • Excellent build quality
  • Great keyboard
  • Cool "green" packaging

Cons:

  • Expensive
  • Overly sensitive touchpad
  • Limited number of ports

Review Lenovo G450

The Lenovo G450 is a 14-inch screen laptop designed for buyers that are on a budget but still want a laptop that is of decent quality and portable enough to take places outside of the home or office. The Lenovo G450 could be a good laptop for students as they certainly have to be cost conscious and portability is necessary to be able to easily carry a laptop in your backpack. I recently found the G450 for a great price so decided to pick it up and try it out for some of the school work I do.

Lenovo G450 laptop

Configuration and Performance

The Lenovo IdeaPad G450 model I purchased came with the following configuration:

  • Processor: Intel T4300 2.10GHz processor, 800MHz system bus, 1MB l2 cache
  • Screen: 14-inch, 16:9 format LED backlit (1366 x 768 resolution)
  • Memory: 3GB DDR3 SDRAM
  • Hard Drive: 250GB (5400RPM)
  • Graphics: Intel Graphics Media Accelerator X4500
  • OS: Windows 7 Home Premium
  • Wireless: Broadcom 802.11 b/g Wi-Fi
  • Optical Drive: DVD Recordable (dual layer)
  • Webcam: 0.3-Megapixel
  • Ports: ExpressCard/34 slot, Three USB 2.0 ports, monitor-out port, Ethernet port, headphone out and microphone in
  • Weight: 4.9lbs

The Intel Pentium T4300 dual core processor that comes with the IdeaPad G450 clocks in at 2.10GHz, although it’s not branded as a more fancy Core 2 Duo processor, the Pentium T4300 actually performs well and if you look at a chart from the benchmarking site CPUBenchmark.net you’ll see it actually performs ahead of some older Core 2 Duo processors:

Intel T4300 benchmarks

So you have no need to worry about the G450 being underpowered if you get the Pentium T4300 processor. In fact, I recommend this processor because it is a lot cheaper than the G450 with the Intel Core 2 Duo T6600 2.40GHz processor.

The Lenovo G450 configuration I have comes with 3GB of RAM, which is ample to run Windows 7. The hard drive storage is 250GB and the spin speed is 5400RPM, which is a standard rotation speed for a budget laptop hard drive. The graphics are taken care of by an Intel integrated X4500, this won’t allow you to do any high-end gaming but for most people running productivity applications on their laptop (email, web, Microsoft Word) this will be more than enough.

Overall I found the performance of the Lenovo G450 to be really quite good, especially for a budget laptop that has a low price of around $500. There is never any slow down when using the computer, though the most I demanding thing I did was watching HD video on sites like YouTube and Hulu.com, the processor had no problems keeping up with the demanding flash decoding that has to be done for HD video.

For those interested in benchmark results, here’s a comparison to the Dell Inspiron 14 and Dell Studio 14z competing 14-inch laptops and then the benchmark results screenshots for the Lenovo G450 are pasted below that:

Lenovo G450 Design and Build Quality

The Lenovo G450 doesn’t exactly provide an eye catching design, it’s a little bland to be honest. The lid is gray in color and has what Lenovo calls a “hairline finish”. Basically it looks like a brush metal finish but quite obviously the lid is made of plastic and not metal. The lid is also glossy and as you will see in the picture below this means that it reflects a fair amount of light and will pick up fingerprints:

Lenovo G450 top view

Inside the laptop the finish is the same as the lid, a gray hairline finish but with a black screen:

The keyboard is black. One nice design finish is that the white indicator lights have a pleasing look. At the top of the keyboard the volume control buttons are touch sensitive and when you press them the buttons glow to indicate they have registered a touch:

The indicator lights below the touchpad indicate from left to right in the above picture that power is on, battery is charging, wireless is on and then finally hard drive activity.

The build quality of the Lenovo G450 is surprisingly good, though the case is made entirely of plastic it is quite rigid and you won’t find much flex to the body. There is some flex in the palm rests, but not enough to notice while you type. The weakest point of the laptop seems to be on the bottom underneath the optical drive, I can push in quite a bit there, due to the fact the optical drive is mostly hollow space this is not an unusual thing. Overall I would give the build quality of the Lenovo G450 a B-, it’s not the best but it is a bit better than I would expect for a budget laptop that cost me under $500.

Lenovo G450 Screen

Lenovo G450 screen

The screen for the G450 is nice and bright, Lenovo rates it at 220-nits, which is good. The display has a glossy finish, meaning the colors are bright and vibrant, but you do get some reflection from the display because of the glossy overlay. For an example of the reflection you get on the screen from bright windows/lights in the room check out the image below:

P1010950

The display is very wide, having a 16:9 ratio and 1366 x 768 resolution, this is good for watching movies in widescreen format but it’s a pain if you have very tall web pages as it involves a lot of scrolling. You can fit a lot of stuff on the screen horizontally, but not vertically. I can’t complain too much about this though, most every notebook made these days has this same 16:9 widescreen format, there’s no getting away from it.

P1010953 P1010952
P1010951

The screen actually has pretty good viewing angles for a laptop, so overall I’d say this screen is slightly above average and most people will think it’s just great.

Lenovo G450 Port Selection

The port selection on the Lenovo G450 is fairly limited, it comes with 3 USB ports, an ExpressCard 34mm expansion slot, one monitor out port, an Ethernet port, headphone and microphone port. I miss having a media card reader built-in, as that makes it easy to transfer images from a camera via SD card, but you could buy an accessory to put in the ExpressCard that acts as a media card reader. The G450 probably has enough ports for most people, but I know some people won’t buy a computer without an HDMI port for high-definition video output, but you can’t expect that in a budget laptop. Below are pictures of each side of the laptop and a description of the ports you will find there:

Front side: headphone and microphone port

Left side: Ethernet, Monitor out, two USB ports and an ExpressCard 34mm expansion slot

Lenovo G450 left side

Right side: USB port, optical drive, power jack

Back side: Just the battery

Lenovo G450 Battery Life

The advertised battery life for the Lenovo G450 is 5 hours. You could probably get that amount of battery life setting screen to the lowest setting and turning off wireless, but that’s not how most people use a laptop. For a realistic test I charged the battery to 100%, then pulled the plug and put the screen brightness at half and left a web page open that refreshed every two minutes. Doing this, the computer shut down with 5% battery life remaining after 3 hours and 55 minutes. You can assume you can get about 4 hours of battery life using the G450 under normal conditions, if you’re doing a lot of tasks it might be closer to 3.5 hours.

Lenovo G450 Keyboard and Touchpad

The keyboard for the Lenovo G450 is comfortable for typing, the keys are actually very “desktop like’, they’re chunky and are protrude up more than an average laptop keyboard with flatter keys. The keys also have a matte finish, they’re not glossy and slippery like some consumer notebooks. The keyboard is solid with no flex, there’s nothing worse than a mushy springy keyboard.

Lenovo G450 keyboard

There are some useful buttons above the keyboard worth mentioning. The touch sensitive volume up, down and mute buttons on the top right are nice and responsive. In addition, the power button on the top left side has a backup system button next to it that makes it very simple to launch an application that allows you to backup or restore the G450 to a previous state.

I’m not a huge fan of the touchpad, it uses a glossy surface that I find is hard to glide my finger across and it just doesn’t feel very responsive, there is sometimes lag. Using the scrolling areas of the touchpad also proved challenging, sometimes working and sometimes not. I’d recommend plugging in a wireless mouse if you’re at a desk or table, otherwise you’ll just have to get used to using the touchpad and it’s quirks.

Lenovo G450 Speakers

The speakers for the G450 aren’t much to write home about, they’re loud enough but tinny sounding like many budget laptop speakers end up being. They’re actually positioned on the screen, right at the bottom where the hinge area is. I don’t know how Lenovo crammed them in there, but needless to say since there isn’t much space there’s no way you’re getting any bass from these speakers. The speakers are fine fine for system sounds and spoken audio, but I recommend using headphones for any music.

Lenovo G450 Web Cam

Worth mentioning is the fact that G450 comes with a 0.3 megapixel web camera. While that is low resolution, it worked pretty well in low light situations and Lenovo provided some nice software for using the web cam so that’s easy to do. Also included is facial recognition software so you can setup Windows to log you in when it recognizes your face instead of having to type a password, pretty cool!

Conclusion

Overall the Lenovo G450 is a good laptop for the price. When spending a limited amount on a laptop you know there will be certain sacrifices such as not having all the ports you might like and a design that isn’t exactly stunning. I like the fact the G450 has a solid feel to it and seems it will last some of the bumps and bruises that come with getting carried around in a backpack. The performance from the Intel T4300 processor and 3GB of RAM was just fine for my needs, the system never experienced slowness when using productivity applications or even during multimedia use. I recommend the G450 to those on a budget, if you can spend $200 more you can find more appealing laptops, but for the price of the G450 you can’t go wrong.
