Lenovo IdeaPad U450 User Review


The Lenovo IdeaPad U450P is a thin and lightweight 14 "widescreen presented in August 2009 for the current line of U series notebooks branded consumer laptops. U450 bridges the gap between the 13" U350and 15.4 "U550. Brochures U are advertised as stylish, portable machines, the media consumption of ultra-low voltage (CULV) Intel and thin LED screens. While Lenovo has managed to combine the perfect blend of performance and portability? Read later to find out!

The revised configuration is 33892GU here that has an Intel Core 2 Duo SU7300 (1.30GHz 800MHz 3MB) and ATI Radeon HD4330 512 MB dedicated video card.



Construction and Design

The dell inspiron 1545 battery is a black plastic casing and slightly rounded corners and edges. The cover and the area around the keyboard (including the palm rest) has a touch like a checkerboard pattern that resists stains, fingerprints and scratches. Some may find distracting or disturbing pattern after prolonged use, but we see this as a design choice that gives this otherwise nice if a bit 'plasticky class and, unlike the common shiny plastic recently. The top of the screen was an emblem of metal, plastic Lenovo integrated in the upper left. The frame around the screen is bright, smooth plastic, black and hinge connecting the body seems fairly typical - the plastic on the outside and not too tight or loose. The device is kept closed by the tension in the joints. A fan on the left. Ports on the back and not just to keep the battery in its place. White LEDs A / C, battery, wireless status, use of the hard drive and touch screen (on / off) are in the lower left of the window. The power button is on the left of the keyboard and Lenovo OneKey (recovery, backups, etc.) is directly above.

Overall, the notebook is well organized with all the components are very durable. The palm of the hand and the case is not based flex and are well supported. Deflection of the screen and can twist a bit ', but there are plans for a laptop this thin - a thin screen that simply can not be perfectly rigid. The fan is in a good position (right) and it is never too hot.

As a 14 ", the area around the keyboard is big enough, and Lenovo has achieved a balance between good profits dedicated controls and disorder. In any case, the design is a bit 'spartan, with only five buttons on the keyboard and more again. The power button (next to the keyboard in the upper left), Lenovo OneKey (just above the power button), volume up / down and mute buttons (beside the keyboard at the top right) and speakers (above the keyboard) is intuitively placed.
The hard drive and DVD player are considered "fixed" (not removable) and repairs and improvements so it will be difficult, requiring navigation through the components inside the laptop. After working with the ThinkPad and Dell laptops to easily remove hard drives and CD drives (often a point of exchange), it was a bit 'of pain, but it is quite comparable to the evolution of consumer laptops.

The fund provides access to a SO-DIMM RAM via two screws removed easily in a plastic mannequin-SIM card connected via a single top and three screws to access the keyboard and internal components below.

The hinges can be a bit 'stronger and the material could be an end a little' higher, but the actual quality of construction is high. The design is the most striking stripes along the entire matter and the subtlety of the laptop. Although a bit 'wide to 14 ", the front of the notebook is actually less than 1" on the table. We found 14 "from a great size for a laptop, and is not an exception, its size and handling characteristics Wight, is ideal for travel and tray tables on the floor, but also used daily in an office.


Screen and speakers

The screen is a 14.0 "WXGA (1366x768 - 16:09) .., bright LED-backlit TFT Lenovo measures at 220 nits, a contrast ratio of 500:1 a camera of 1.3 megapixel fixed-focus the Above screen is in the frame of the screen is free of dead pixels .., quite bright in the clear and can be disabled by pressing Fn + F2 whites are a bit 'cooler and possibly more in particular in relation to portable screens elderly couple - probably a color relatively new LED backlighting are vivid and text is clear that the native resolution is more or less ideal for a laptop of this size in a random check reveals a dark room ... no light leakage or access points.

From left to right viewing angles are surprisingly good, but the viewing angles from top to bottom are typical of a little 'weak. The "sweet spot" is large enough that it should not cause problems. The screen can be folded about 125 degrees - a little 'surprise, but not a problem. If the bright WXGA screen for you, this laptop screen does not fall short. The ATI Catalyst Control Panel (included with the discrete graphics card) gives plenty of adjustment options. In combination with the video card, the screen is ideal for multimedia applications, lights and anything that requires a mid-range GPU.

Two speakers are left and right on the keyboard. Lenovo says it is a "home theater system, Dolby sound with two stereo speakers," but it would be more accurate to say only slightly better than the traditional notebook. They get pretty loud, but louder the volume, his tinnitus. In the better. The headphone jack or the HDMI port will be essential reading for any serious music (later). Volume up, down and mute buttons adorn the right side of the box next to the keyboard. To be honest, the speakers are terrible for a laptop, and probably a little 'above average, but when external speakers are available, will obviously be preferable.


Keyboard and touchpad

The keyboard of this macbook pro battery is a bit 'better than average. The size, the space key on the keyboard and feel are strong. Race distance and a sense of movement are clearly affected by ideals and Thinkpad design. The fundamental sound is solid, while a little 'off. There is some flexibility on the keyboard when you apply a strong pressure, increased left to right, but nothing remarkable use of a normal character. The unique features of the keyboard has a narrow, squeezed between Ctrl and Alt key in the Windows flag on the left of the spacebar, and a Fn key as the key to the left of the Ctrl key. Caps Lock and security numbers (F8), the keys have LEDs in them to show white when activated. No numeric keypad, but the orange Fn key allows access to a number of additional buttons, including volume controls and brightness buttons. In general, you might have a little 'less flexible, but generally exceeds the quality of most consumer portable keyboards.


The Synaptics touchpad is typical of a large area of movement and two separate large buttons, plastic metalicized below. The material is soft, frosted plastic and comfortable and easy to run a finger width. The speed is just outside the box. The section of the touch screen has a line of orange dots almost tangible, indicating that the finger can scroll up or down to scroll. Multi-touch is compatible. The touchpad is nothing special, but does the job. A microphone is located immediately to the left of it, so the sound recording when using the touchpad or write can cause a conflict.



Ports of entry and exit

On the left are two USB ports side by side (but decently large space for a USB dongle), a Gigabit Ethernet port, HDMI (HDCP), VGA, fan, power outlet and a locking slot.

This is a great mix of ports in strategic locations. The headphone jack could cause problems for people with a right mouse next to the laptop, but otherwise, nothing essential is missing or misplaced. The laptop has no expansion slots PC Card slot Express Card o, three USB ports, but essentially this excuse. An S-Video, a FireWire port and the bay would be interchangeable as pleasant, but certainly not essential - especially on a laptop in this category.


The 3.5 mm headphone / audio jack provides some information on your top in all the volumes for the connection to the wall. When off the field decreases and becomes a bit 'more remarkable. This is not a major problem, and is fairly typical of mobile phones, but note for audiophiles out there. An external sound card will be required to obtain a pure sound.


Performance and benchmarks

This configuration comes with an Intel Core 2 Duo SU7300 processor (1.30GHz 800MHz 3MB) and 4 GB PC3-8500 DDR3 SDRAM 1066 MHz (2 x 2 GB). The computer is running Windows 7 and typical programs - word processing, web browsing, photo management - no problem. Since a processor ultra low voltage model, however, there are a couple of advantages and disadvantages. While the battery life extends beyond the normal Core 2 Duo chips loop slightly under load. There are some incidents that passes between the main program or process from the CPU. Configurations with less CPU is likely to fight even more, and may have some performance issues with many demanding programs running. The video editing and serious gaming on this machine is not recommended (but probably the GPU can handle modern games medium-low values), but given its size and target audience, this should not be a problem, activities office and should not be a daily challenge. The startup is fast and decent 4GB of RAM is more than enough for almost all the installed programs to run simultaneously, but slowly. 5400 rpm drive is and can be a good target for an update at 7200 rpm or SSD for those seeking the best possible performance.

All benchmarks were performed after removing bloatware in the administration of energy efficiency and costs after a reboot. Catalyst Control Center has been set for the performance and the default resolution was used. An antivirus program is kept in the background.

The handset has 37 seconds to access the login screen of Windows and a minute to get a usable desktop connected wirelessly at home.


The heat and noise

This dell latitude d630 battery does not heat up and becomes ever stronger, even under load. The hard drive is almost silent and the fan is pretty quiet, even at its best. You can sleep with this laptop, even his height. The hot spots are below the touch screen and ventilation. Neither warms on contact. During operation, the CD is clearly audible, but not most laptops. This is a very quiet notebook.


Wireless

The Intel WiFi Link 5100 wireless card 11a/b/g/n works better than many other wireless devices that worked, collecting dozens of local access points are usually not seen. Windows 7 works well with, so wireless connections easier than ever. Bluetooth is ready, and the combination of an intuitive device. Bluetooth mouse pairing simple and requires no additional drivers. The team may have an antenna for 3G connections, but the SIM card slot that connects is permanently sealed. This is not a major loss, but again, a little discomfort. Wireless works very well together.


Battery

The battery is a 6-cell lithium-ion 5200mAh, 57Wh. It fits in the back and has a locking lever and spring, plastic held in place. Using computer power management mode Energy Star - by default - as a 239 (3 hours, 59 minutes) minutes of power while surfing the Internet (WLAN and Bluetooth), watch videos, and pick up some open programs. It 'a moment for a team with a decent dedicated GPU, but low for a notebook CULV. Strict power settings, turn off the wireless transmitters and closing processes and programs, no doubt, add more time, but with a low-voltage processor, we expected more.


Operating System and Software

The computer comes with Windows 7 Home Premium 64-bit, no problem - lenovo t400 battery calls a "best experience" and apparently made some adjustments and changes, but exactly what is not immediately apparent does not include. Recovery discs. The Lenovo OneKey Recovery Console allows you to create recovery discs (which requires two different DVD or CD) and the backup system of an image file. The team has a hidden partition in order to retrieve the touch of a button factory and a separate partition for drivers only.

However, the default condition includes an incredible amount of bloatware. The kit comes with a lot of trial-ware, adware and utilities are not needed. It took about 30 minutes to uninstall unneeded programs, leaving only the necessary services to Lenovo. Change of energy profiles of performance management can make a difference in overall speed of the system. Changing the default value of "Energy Star" to "high performance" changes the screen brightness and CPU usage significantly.
Over time, a little 'more, you can download a clean copy of Windows 7, you must install it using the key at the bottom of the laptop and install all the drivers and software components separately from the disk or a partition of the Lenovo site. This will almost certainly lead to increased performance slightly.

The distribution of hard disk partitions of 320 GB is a hidden partition OEM 14.75GB, a 252.88GB 200MB hidden C: 30.25GB and D: for drivers. All are formatted as NTFS. About 90% of C is at the finish.


Customer Service

The handset comes with 1 year parts and labor? Warranty. This laptop was purchased with an additional year in the days of on-site repair next-generation business to Lenovo. There is also support 24x7 free warranty issues during the warranty period at 877-453-6686. This service has not been proven, but Lenovo has a reputation worthy of support and on-site repair is generally considered good.


Conclusion

The dell latitude e6400 battery is a thin, well-built, fully portable CULV ideal for consumers looking for a balance between performance and portability. At the price point, the U450P competes with other similar systems (for example, the Dell Inspiron and Dell Studio 14Z 14Z), and probably beat the style and slim. The main users of the web office software, multimedia and realize they can walk with a machine that can handle virtually anything thrown at him. The parameters of the video card is a bit 'a paradox, since the addition of a power-hungry GPUs, defeats the point of getting a CULV, but give better support. The players really do not need to ask (in spite of configurations with discrete graphics games many possibilities). It lacks a few bells and whistles, is a bit 'expensive, and some minor problems, but they are reasonable compensation for one of the most powerful and elegant Culver on the market.
