Summary: Microsoft does not give consumers the ability to capture screenshots in Windows Phone, but now you can easily unlock your device for development purposes.

“Microsoft has created a mobile demo site to promote Windows Phone’s features to consumers.”

Still tempted by the fruit of another? If you’re looking Microsoft’s way, but aren’t quite ready to toss your adoration for iOS or Android aside, the coders in Redmond are giving you an alternative to quitting cold turkey.

Microsoft has created a HTML5 demo of the Windows Phone operating system that works on iOS’ Mobile Safari browser and Android’s mobile browser. The web demo is a pretty simple way for iPhone and Android users to get a feel for the Metro UI using their existing hardware. It is not as full featured as handing them your Windows Phone but it is a fun way to show off the Windows Phone experience. To try it, point the mobile browser to http://aka.ms/wpdemo, you’ll be immediately tunneled into a emulation of Windows Phone 7. We gave it a test run here at Engadget HQ, and it seems that every tile and swipe save for Apps runs properly. Can’t say the fonts and such looked as smooth on our Galaxy S II as they do on the Radar, but it’s a solid effort that’ll definitely serve you well if you’re considering the switch. Just don’t try to flip the demo horizontally — that’s clearly a no-no.

With the latest iteration of its ID47 notebook, Gateway kept everything we liked about the previous version–an aluminum alloy chassis, an utra-thin bezel, and USB 3.0–and bumped the specs. You now get a faster processor and Intel’s Wireless Display technology but at the same reasonable price of $699. Is this the 14-inch system for you?

Design

Click to EnlargeSporting a brushed aluminum-alloy lid and deck, metallic-colored keys, and a slick dark blue-tinted touchpad, the Gateway ID47H07u oozes style. Even the matte-black bottom and sides have a smooth surface, with a minimum of extraneous holes and grooves. The 0.2-inch black bezel surrounding the screen not only fits a 14-inch display in the same space normally reserved for a 13-inch panel, but it also adds a unique design flair.

Thanks to its thin bezel, the 13 x 9 x 1.1-inch Gateway ID47H07u is about half an inch shorter than many other 14-inch notebooks, such as the Dell Inspiron 14z (13.6 x 9.7 x 0.9 inches) and the 13.4 x 9.2 x 1.2-inch Lenovo IdeaPad V470. At 4.4 pounds, the ID47H07u is a hair lighter than the Inspiron 14z and the V470, both of which weigh 4.6 pounds. The HP Pavilion dm4t is a little thicker, but it has the same weight and depth, at 13.4 x 9 x 1.3 inches and 4.4 pounds.

Keyboard and Touchpad

Click to EnlargeThe island-style keyboard on the ID47 provided reasonable tactile feedback, good key placement, and a comfortable deck. However, the keyboard did show a small amount of flex, particularly when we pressed down on the G and H keys. We do appreciate that the function keys are reversed so you can adjust the brightness and activate media controls without using combos.

The fairly large 3.9 x 2.3-inch Synaptics ClickPad has a slick, glossy surface with a unique blue color. Navigating the desktop wasn’t difficult, but the touchpad picks up fingerprints easily and creates a little more friction that we’d prefer. Multitouch gestures such as pinch-to-zoom worked, but weren’t as smooth as we would like. Those who use the touchpad with two fingers will experience some jerkiness. You can also scroll with two fingers and use a four-finger swipe down to show the desktop at any time.

Heat

The Gateway ID47H07u stayed pleasantly cool throughout our testing. After streaming a video for 15 minutes at full screen, we measured the touchpad at 82 degrees, the keyboard at 80 degrees, and the bottom at a chilly 81 degrees Fahrenheit. We consider temperatures below 95 degrees comfortable.

Display and Audio

Click to EnlargeThe Gateway ID47H07u’s 14.1-inch, 1366 x 768 glossy screen provided sharp, rich images. When we tried watching both a 1080p QuickTime trailer forImmortals and a 1080p YouTube trailer for Mission Impossible: Ghost Protocol, images were crisp and motion was smooth, but colors inverted at even 45 degree angles. Dark areas also showed a high amount of backlight bleed.

Using an AEMC lightmeter, we measured the brightness of the screen, which averaged 153 lux. That’s better than the Lenovo V470 (144 lux), but not as good as the Inspiron 14z (194 lux).

The stereo speakers, located on the bottom of the Gateway ID47H07u, provided accurate audio that was loud enough to fill a room. When we streamed it from Pandora, Maroon 5′s “Wake Up Call” was rich and clear without any distortion. We could really hear the twang of Eric Clapton’s guitar strums in “Lay Down Sally,” and there was nice separation of instruments, too. The Dolby Home Theater v.4 software makes a huge difference, as all songs were flat when we toggled the application off.

Wireless Display

Click to EnlargeBuilt in to the ID47 now is Intel’s Wireless Display technology, which lets users stream content wirelessly from the notebook to a larger display, provided you have a receiver such as the $99 Netgear Push2TV HDTV adapter. Unfortunately, you will have to purchase this separately.

Ports and Webcam

Click to EnlargeThe Gateway ID47H07u has a generous selection of ports, including one USB 3.0 connector that allows you to connect high-speed external hard drives and docking stations. The right side of the laptop houses an Ethernet port, a Kensington Lock slot, and that speedy USB 3.0 port. A VGA port, HDMI, audio in/out, and two more USB ports line the left side. The front lip sports a 5-in-1 card reader.

The 720p webcam provided sharp and colorful images when used near a light source, but it suffered from a lot of visual noise when we used the cam in a dark area of our living room. When we were talking on Skype in a dim area with a light source behind us, fine details of our face were visible, though shadowed.

Performance

With its 2.4-GHz Core i5-2430M CPU, 4GB of RAM, Intel HD 3000 integrated graphics, and a 5,400-rpm, 500GB hard drive, the Gateway ID47H07u provides strong performance that’s good enough for demanding tasks.

On PCMark07, a synthetic benchmark that measures overall performance, the ID47H07u scored a strong 2,342, slightly above the 2,171 thin-and-light notebook category average (and the same score as the older ID47). The new ID47 was also predictably faster than the Core i3-powered HP Pavilion dm4t (1,869) and the IdeaPad V470 (1,821). However, the Dell Inspiron 14z we tested with a 2.3-GHz Core i5 CPU notched a higher 2,562.

The 500GB, 5,400-rpm hard drive booted into Windows 7 Home Premium (64-bit) in 1 minute and 4 seconds, almost dead even with the 65-second category average. The drive took a 2 minutes and 58 seconds to complete the LAPTOP File Transfer Test, which involves copying 4.97GB of mixed-media files. That’s a rate of 28.6 MBps, a little above the 26 MBps category average and the 24 MBps provided by the HP Pavilion dm4t. However, the Lenovo ThinkPad Edge E420s’ 7,200-rpm drive notched a speed of 31.6 MBps.

On the OpenOffice Spreadsheet test, the ID47H07u took 5 minutes and 27 seconds to match 20,000 names to their corresponding addresses, which is 1 second faster than the Inspiron 14z (5:28), about 40 seconds faster than the category average (6:10), and much faster than the V470, which took 7:51.

Graphics Performance

Don’t expect to do any serious 3D gaming with the Gateway ID47H07u’s integrated Intel HD 3000 chip. On 3DMark06, a synthetic benchmark that measures overall graphics prowess, the notebook scored a modest 4,176. That’s slightly below the category average (4,370) and well behind the Dell Inspiron 14z (4,579). Still, the Gateway was better than the HP dm4t’s score of 3,466.

On autodetect settings, the ID47H07u managed 36 frames per second in World of Warcraft, which is playable but half the 74 fps category average. However, when we turned the settings up to maximum, that rate dropped to an unplayable 13 fps, half the 29 fps category average.

Battery Life Test

Click to EnlargeThe Gateway ID47H07u packs enough juice to last just about all day. On the LAPTOP Battery Test, which involves continuous web surfing over Wi-Fi, the ID47H07u lasted a strong 7 hours and 48 minutes, 40 minutes longer than the ID47H02u Gateway squ-412 battery, and more than 2 hours longer than the thin-and-light notebook category average of 5:32. The Pavilion dm4t managed a time of 7:02, while the Inspiron 14z lasted 6:18, and the V470 lasted 4:56.

Configurations

Our review configuration, the ID47H07u, costs $699. For that price, you get the 2.3-GHz Core i5 CPU, 4GB of RAM, and a 500GB hard drive. For $629, you can get the ID47H06u, which has a 2.2-GHz Core i3-2330M CPU, a 500GB hard drive, and 4GB of RAM.

Question: Should I Remove the Laptop Battery For A Desktop Replacement Laptop?

I have a laptop at home which I use as a desktop replacement. As such, 99% of the time the laptop is being used it is plugged in. I wonder if I should remove the battery so that it is not permanently being charged, or does the laptop cut off the current to the battery once it is fully charged? I do unplug the laptop when I turn it off.

Answer:

When using a laptop as a desktop replacement the battery should not be left in for long periods of time. The laptop will over time discharge the battery. Remove the Dell laptop battery – making sure that it is charged to 40% and store it in a dry, warm place. Ensure that it is wrapped protectively and nothing will be dropped on it.

The IBM thinkpad battery should be re-installed every 3-4 weeks and allowed to fully discharge. Leaving a battery in storage for longer than this without using could cause the battery to fully discharge as the circuitry of the battery itself consumes power.

Leaving a battery in a laptop while using an electrical outlet for long periods of time will keep the battery in a constant state of charging up and that will reduce the life cycle of the battery.

A new approach to alkali batteries, in which the cathode is dissolved in water that flows through the system, could overcome the limitations of currently available batteries, scientists in the US say. Rechargeable lithium-ion batteries have revolutionised the mobility of small electronics, but their limited capacity means they don’t stretch easily to bigger jobs such as running automobiles or storing power for national grid networks.

Ordinarily, lithium ion batteries contain a solid anode, which gives up electrons, and a solid cathode, which receives them. The two are divided by an organic fluid electrolyte. This strategy depends on a cathode that can expand to host additional lithium ions from the anode during discharge and contract to release them during charging. The solid’s limited ability to change its volume caps the battery’s capacity, and the expansion and contraction is also a source of wear.

Aqueous cathodes in ‘flow through’ batteries are not a new idea, but Yuhao Lu, John Goodenough, and Youngsik Kim at the University of Texas in Austin, US, are the first to suggest them as the next phase of lithium-ion technology. Their design places a solid alkali ion electrolyte between a lithium or sodium anode and an aqueous cathode comprising a metal – in this case iron – in two oxidation states. The cathode solution flows through the system from an attached storage tank, so its total capacity can be much greater than that of a solid. Moreover, because the cathode is a liquid, it avoids the volume changes as lithium shuttles in and out.

To test the idea, the team used a commercial electrolyte called lithium superionic conductor (Lisicon) with a solid lithium anode. An iron cyanide cathode met many of the requirements for a successful HP 485041-003 laptop battery: it’s chemically stable, it’s soluble in water and its high potential of 3.4V with lithium means it is on par with commercially available lithium-ion alternatives.

The electrolyte restricted their initial experiments to a proof of concept only, says Goodenough. But a thinner, more stable lithium ion solid electrolyte is already under development in his laboratory.

Rob Armstrong of the University of St Andrews in the UK describes the work as ‘highly significant’. Although the solid electrolyte requires improvement, he says, ‘the suitability for both static energy storage associated with renewable energy generation, and for electric vehicles, means that this represents a very promising avenue for future research, alongside lithium-air and lithium-sulfur batteries’.

Your iPad comes with a large lithium-ion battery, and Apple claims the iPad Battery gives you up to 10 hours of continuous usage and hold a charge in standby mode for 30 days. Those are impressive times, although count on getting less in the real world.

The biggest down side to the iPad battery is that it’s not, in Apple parlance, a user-installable feature. If your battery dies, you have no choice but to return it to Apple to get it replaced. Which is all the more reason to take care of your battery and try to maximize battery life.
