Battery Life LENOVO G550 Battery The default provided battery for the 6910p is a 6-cell 55WHr battery that performed reasonably well. With wi-fi on, screen at half brightness and in ‘Balanced mode’ the battery gave 3 hours and 37 minutes of life. Half of that time the notebook idled and the other half it was used for light office work. You can expect somewhere between 2 and 2.5 hours if you’re playing a movie with screen at full brightness, while if you’re doing light work with screen brightness down you could probably get over 4 hours of battery life. FUJITSU SIEMENS ESPRIMO Mobile V6555 Battery Keyboard and Touchpad The ALPS touchpad used on the Mini 311 is a multitouch gesture-enabled model that allows you to use multi-figure gestures such as “pinching” your fingers together or “pulling” your fingers apart to zoom in or out. The ALPS control panel in Windows also allows you to customize these gestures as well. Sensitivity and tracking seemed accurate even when you move your fingers quickly over the touchpad surface. Speaking of which, the touchpad is covered in a glossy smooth surface that sometimes makes it east to slide your finger across the surface and other times causes your finger to “skip across the surface because of the lack of texture/traction. The left and right touchpad buttons are located beneath the touchpad and each button has shallow feedback with loud clicks when pressed.
The Sony SZ is the most expensive of the three, but is also the lightest and has the best screen. However, I discovered that Sony does not provide an option for extended international warranty beyond the standard 12 months and for a notebook costing this much, I’d prefer it to have warranty coverage for at least 3 years since Sony notebooks are known to be extremely expensive to repair after the warranty expires. The HP comes with a 3-year onsite parts and labour international warranty, which presents a better investment in the longer term. In addition, the SZ didn’t look as durable when I tried it, mostly due to the thin LED-backlit display which causes it to creak upon opening. The D620 is also a viable alternative to the nc6400, but I didn’t really favour its design, aesthetics are a major factor in my purchase. Besides, I have also heard horror stories about its dimly lit WXGA+ resolution screen. The full-size keyboard is one of the main reasons I opted for this model, having typed on an nx8420/nc8430. It is very nice to type on and exhibits no flex and is quiet, unlike those keyboards found on the Presario and Pavillion notebooks. The keyboard features dual pointing devices, meaning it has a pointing stick with corresponding buttons as well as a normal touchpad and mouse buttons. The touchpad has a hardware controlled dedicated vertical scroll area, which is a nice touch.As this is a business notebook, there are no so-called “multimedia keys” except volume control buttons. However, there are dedicated presentation, wireless and help keys which can be found on other business notebooks too. In addition, there are function keys to adjust brightness and to control the ambient light sensor. The CTRL and FN keys are in the normal position, but these can be switched in the BIOS according to user preference.The WXGA+ display is made by the manufacturer AUO. It is certainly not the best display on the market due to a slight shimmering effect of the anti-glare coating which is apparent only at a very close distance. Vertical viewing angles are pretty narrow, but horizontal viewing angles are fine. The higher resolution is definitely a plus for me as I require the screen real estate and this is the highest resolution I can get for a notebook of this size. The screen has a light sensor that automatically adjusts the LCD backlight brightness according to the room’s lights. I find it quite useful indoors. This is also one of the first HP models to feature a privacy filter option, allowing you to prevent others from observing what’s on your screen from non-perpendicular angles. Unfortunately, I do not have one to test. Fujitsu Siemens Amilo Pi 2515 Battery 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. The HDX shares several design elements with the rest of the HP Pavilion line, but more than size and weight separate the HDX from its siblings. First, HP has improved their glossy black and silver "Imprint" finish with a new high-impact version called "Dragon." While we didn’t test the high-impact finish by dropping it repeatedly in our office, I can say the finish looks quite durable … though fingerprints show up quickly on the glossy finish. The real stand out design feature on the HDX is the dual-hinge display. Rather than opening with a single large hinge at the back of the notebook, the 20.1" display swings open with a center-mounted rear hinge and is further adjustable with a second hinge at the back of the display allowing you to position the screen for the perfect viewing angle. Although the HDX’s weight of 15.5 pounds might sound excessive, keep in mind that other 20" notebook configurations such as the Dell XPS M2010 are closer to 20 pounds. That said, the HDX would have been more portable if HP had included a built-in carrying handle. The low-cost ultraportable notebook or “netbook” market might have exploded in 2008, but HP plans to take the top spot in 2009 with the all new Mini 2140. This business-grade netbook features a 10.1-inch screen, a remarkably large keyboard, a high capacity hard drive, and plenty of impressive specs. Did HP learn from the mistakes of the past? Is the Mini 2140 this year’s ultimate road warrior machine? Keep reading to discover the answers.
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.
