HP Pavilion dv4 Review - Bring more innovation for users

HP Pavilion dv4 ability to handle graphics very well over the model range with money, but battery life is quite short.

HP Pavilion dv4 series model 3000 can be regarded as typical of the new MUSE design philosophy of HP in 2011. Continued improvement of strength is the line for entertainment, the Pavilion dv4 is the Altec Lansing speaker, hardware with Intel latest Core i Sandy Bridge, USB 3.0 and higher capacity battery.

Version tested Pavilion dv4 equipped 14 inch screen resolution 1366 x 768 pixels, Intel Core i3-2310M 2.1 GHz, 2 GB RAM, 500 GB hard drive capacity, chip Intel graphics HD 3000 821MB Graphics card and AMD Raedon HD 6750M left. The unit is pre-installed operating system - Windows 7 Home Basic 64-Bit.

Design.

Contrary to the trend of design lumpy plastic last year, HP continued to hold traditional polished for  Pavilion line. Plastic cover still in light plastic create a modern definition for the machine, but very dirty. As always, remains compact HP logo in the lower left corner on the face but can not emit light as the old Pavilion.

HP advertising machine can scratch resistant but the reality of this phenomenon is likely to occur if there is contact with sharp objects.

A sharp change in the new Pavilion line of the hinge design quite curved. This also makes the edge  rearwards of the area may have more than giving the company can arrange slot cooler here.

Except eSATA port, this model equipped with almost all the common ports like USB 2.0, VGA, LAN, and HDMI. USB 3.0 port on your computer without the green features as most other models that have more symbols to identify SS front. Do not leave the vents for heat, so the port layout is quite comfortable. Two source signals were placed near the right side USB port.

Keyboard, touchpad.

Series Pavilion in recent years has left HP keyboard that changes its characteristics with chiclet keyboard. Itinerary keys on this model was short but in a sense tap and heated well made on the operation completely comfortable. However, two navigation keys are up and down so small that the press is prone to error, especially those with large fingers.

Pavilion is a line of machines for entertainment, but no distinct multimedia keys integrated keyboard straight up. Interestingly, the volume button, brightness, or pause / play is the main function key while pressing the key for F1, F2, ... The user must press the Fn key added.

In contrast with the shell and parts to fingerprint, the machine's touchpad has given rugged that is not slippery hands when using. Even with a little sweat, users can be confident that operations are not affected much. Mouse is very responsive and light is also another plus point for this touchpad.

Screen.

As a mid-range models of the Pavilion dv4 should display screen of the mirror as well as most other models. Screen Size 14 inch 1366 x 768 resolution for crisp images, vibrant colors but very limited perspective. In addition to the edge of the screen also makes the plastic ball used outdoors or in front of bright light source can cause problems for users.

Performance.

Pavilion dv4 version equipped with Intel Core i3-2310M 2.1 GHz, 2 GB RAM, 500 GB hard drive capacity, graphics chip Intel HD 3000 821MB Graphics card and AMD Raedon HD 6750M left.

Using PCMark Vantage program to assess the overall strength, 5692 HP Pavilion dv4 reach points, higher scores compared with systems using other Core i 2011 but lower than the model with 4 GB RAM memory card but low graphics than the Vaio E as previous reviews.

Using AMD's discrete graphics card, Pavilion dv4 for great graphics power to reach 9,841 points when evaluated by the program 3D Mark 06. This score is very impressive if compared with other models equipped with discrete graphics card with a lower score in the range from 6,000 to 7,000 points.

With discrete graphics chip, computer game play is quite good as Need For Speed ​​Shift rate of 41 frames per second at the highest setting.

Continue to use the program to evaluate Cinebech 5.11 processor and try OpenGL. The results achieved with the processor by using only 2.02 points i3 but the graphics chip average to 39.65 frames per second.

Pavilion dv4 hard drive that uses the speed of 500GB 5,400 rpm / min produced by Toshiba. In fact, the average read speed of data on the drive was 50.7 MB / sec, much lower than the average 60 MB / sec at the same speed and hard drive capacity.

Radiator.

Using new HP technology Coolsense with the introduction of next slot after cooling the machine, Pavilion has very good heat dissipation capability, than compared to the previous life of the HP laptop. Hot parts of the computer keyboard on the surface are displaced and not to focus too much on the left half of the same models. May just underneath the heat but can still use when placed on two legs.

Battery.

Using the 6 cell battery capacity 52 WHR, higher than the ordinary flow only from 47 to 48Whr. Machine takes about 3 hours to fully charge if unused for more than 3 hours and 40 minutes for charge has used.

Tested: Firefox web pages load 10 and for automatically refreshes every 15 minutes, to open an online music site and play back continuously, using a headset instead of speakers and the volume level to 70% of 50% for your morning run until itself off (even at 5%), the time it reached 2 hours 51 minutes.

While testing the machine running a 720p and play back continuously until the machine off, turn off Wi-Fi connection, using a headset instead of speakers and the volume level to 70% (negative bar of Windows Media Player program to 100%), brightness 50% for treadmill until itself off (even at 5% battery), the time it reached 2 hours 38 minutes.

Contrary to the battery, this model for the battery life is quite bad, not three hours while the other is on the Common 3 hours, most likely due to the switch chip and integrated graphics card not really leave well reduce the machine's efficiency.

Sound.

One of the highlights in the Pavilion's speakers. Altec Lansing is still the "luxury" but was designed dv4 front edge of the machine. Sounds pretty big and entertaining enough individuals in the room over 25 m2. More natural treble speakers should fit on the line listening to soft music is much more than the bass.

Unfortunately there are no shortcuts own entertainment that integrates directly into the keyboard.

Touchpad.

E Vaio touchpad is quite good. The still floating on the surface created using the response should not be slippery. TouchPad works quite sensitive and accurate. The two mouse buttons have by reason of moderate to press at ease and comfortable.

Screen.

E Vaio new version still uses 14-inch glossy display resolution of 1366 x 768 pixels. The screen is quite glossy after use but very sharp image and good color. Slightly narrow viewing angle of about 45 degrees from side to side with the square screen before the picture went dark and glossy. To fix this, you should increase the screen brightness to minimize shadow.

Performance.

Do not use discrete graphics, but the Vaio E has reached 3,461 points when assessed using 3D Mark 06 program. This score equally popular models equipped with second generation Intel Core i3 but Nvidia's discrete graphics card like Acer 4750G. This score is approximately an average of more than 3,100 points in the aptop use Core i5 and no other discrete graphics card.

With integrated graphics chip, the machine is not easy to handle normal game. In the experiment with the game Street Fighter IV, the frame rate just stop at 23 per second.

Continue to use the program to evaluate Cinebech 5.11 processor and try OpenGL. Results of the processor and graphics reached 2.57 points on average to 8.08 frames per second.

E Vaio hard drive that uses a 500GB speed of 5,400 revolutions / minute produced by Samsung. In fact, the average read speed of data on the drive was 65.1 MB / sec, a little more than an average of around 60 MB / sec at the same speed and hard drive capacity.

Part 3: Radiator, battery, audio

Radiator.

E Vaio does not use the fan inlet at the bottom but many slot heatsink and thick handset so heat dissipation capability of this model is quite good. The temperature when the CPU running full-load, 100%, the temperature of the processor is only increased by about 68 degrees C after half an hour. The temperature was 67 degrees C in the mail when the drive is about 35 degrees C. With this temperature there may still be used normally on two legs. Test on in a room with average temperature 25 degrees C.

Battery.

Using the 6 cell battery, Vaio E took nearly three hours to fully charge if unused for more than 3 hours and 30 minutes if you just have to use charger.

Toshiba Portégé R830 Reviews: worthy laptop for entrepreneur

Portégé R830 is the performance and battery life is very good but the weakness of radiator from the R700 has not improved much.

After the arrival of the R700 is rated quite high last year, Toshiba continues to bring in business models is one of the development objectives of its most important this year with the R830. An upgraded version of the Portégé retains the advantages such as lightweight, shell be sure, bold business styling . Not only that, the R830 also owns the configuration upgrade to an Intel Core i5 second generation (Core i7) and  some other improvements in features.

Toshiba Portégé R830 equipped with 13.3 inch screen, Intel Core i5-2520M-speed 2.5 GHz, 4GB RAM (upgradeable up to 8GB), 500GB hard drive speed of 7200 revolutions / minute , Bluetooth 3.0, USB 3.0. This is the model being tested, evaluated in the article.

Design.

R830 is not much different R700 in design in overall general. Machine still owns the crust with aluminum, magnesium alloy is very uncertain. Bearing capacity impact when dropped from a height of 70 cm and take more energy to the equivalent of 100 kg on the top of the machine. R830 has a thickness of only about 1.9 cm and weighing from 1.4 kg. These parameters are not significantly different from the R700, but not too special and outstanding as last year due to ultrabook ultraportable line is attracting much attention from consumers.

Arrangement of the ports of the machine was refined this year than last year when the VGA port is designed how far the slot radiator to avoid the harmful effects of the heat out. Also, the distance between the VGA port and the port is also wider to the rest room for the VGA cord from the projector or large screen.

R830 also has a slot in the bottom dock. This device will add more to the increased battery life and graphics for the Portégé R380.

Keyboard, touchpad.

R830 continue equipped chiclet style keyboard as R700. Key size is quite small at first glance but with distance and size according to standard. Journey of keyboard a bit short, but in return the good bounce and smooth feeling very comfortable for the user. The navigation keys are also easy to get used to surf the web or even see the text a bit smaller than the remaining keys.

A pity the R380 is not backlit keyboard, a defect is quite unfortunate and surprising for a model for entrepreneurs.

Touchpad of the year may retain the advantages of sensitivity and response to avoid slippery as R700. Furthermore, to overcome the weaknesses of the button, the R830 has two mouse buttons are lighter and shorter than the keyboard feels comfortable to use than its predecessor.

Screen.
.
Toshiba Portege R830 using the anti-glare screen with LED backlight technology resolution 1366 x 768 pixels. Machine can display well when used outdoors or at the rear lights. However, your perspective is really good, only about 60 degrees from the perpendicular to the screen from side to side. Angle from the top down or bottom up even less.

Machine display color is quite good but the resolution just as the ordinary laptop that R830 not shown true class.

Performance.

Toshiba Portégé R830 equipped with 13.3 inch screen, Intel Core i5-2520M-speed 2.5 GHz, 4GB RAM (upgradeable up to 8GB), Intel HD graphics chip integrated with microprocessor Core i5 rly second generation, 500GB hard drive speed of 7200 revolutions / minute.

Scoring in Windows Experience Index.

With hardware like this, this model achieved 4.7 points (get low score by clicking the graphic capabilities) when put in the system Windows Experience Index in Windows 7 Professional (64bit) installed. On a scale of detail, to reach 7.1 point processor, RAM memory is 5.9 points while the graphics capability is 4.7 points and graphics for the game to reach 6.1 points.

Ratings by PC Mark Vantage.

Continue using PCMark Vantage program to assess the overall strength, Portégé reach 6,957 points, the better score compared to an average of almost 6000 points in universal laptop also uses Intel Core i5 the second generation.

Grading in 3D Mark 06.

Do not use discrete graphics, but the R830 still reach 3,495 points when evaluated by the program 3D Mark 06. This figure is even comparable with the popular models equipped with second generation Intel Core i3 and discrete graphics from Nvidia, such as Acer 4750G. This score is higher than the average over 3000 points in the laptop chips Core i5 and no other discrete graphics card.

Ratings processor.

Continue to use the program to evaluate Cinebech 5.11 processor and try OpenGL. Results of the processor and graphics reached 2.71 points on average to 8.29 frames per second.

Drive the R830 uses a rate of 500GB 7,200 rpm / min produced by Hitachi. In fact, the average read speed of data on the drive was 85.8 MB / sec, the equivalent figure is about 80 MB / sec at the same speed and hard drive capacity.

Radiator.

It is very unfortunate that heat dissipation capability of R830 has not improved much compared to the predecessor R700. Still using a bottom intake fan to increase the ability to regulate cooling airflow within the machine, but this model is still quite hot when in use. According to the figures above, to idle about half an hour with 100% CPU mode (full-load) the machine heats up pretty fast. CPU temperature rose from an average 47 degrees C when booting up to more than 80 degrees C. The temperature inside the machine also increased accordingly.

Temperature difference between the two halves of the machine is quite big, fast heat up the left side while the right is very cool because almost no elements radiate more heat treatment here.

However, if used moderately with the application of web surfing and office with temperatures around 24 degrees C, this model is still fine, but hardly offensive.

Battery.

Do use high-capacity battery Portégé R830 takes longer to fully charge. Machine takes about 4 hours to fully charge if not used and just over 4.5 hours if you used the last charge.

These figures show that the battery life of the Portégé R830 is very good. With the results of this test procedure, the user can safely use the normal range 6 continuous hours without recharging or a day's work (more than 8 hours) with the Eco mode.

Sound.

Like the R700, R830 system is not good quality speakers, the drawback often seen on the series for entrepreneurs. The system for small volume, enough to hear in the room below 20 m2 but not good quality natural sound with much less treble on the bass. When large open end sized sound even slightly cracked

Design

According to the current trend on the cheap new Acer Aspire 4750G still own crust floating fake carbon fiber made of plastic though. This design has brought modernity and luxury to both a machine against dirt during use.

Aspire 4750G is pretty neat design though the screen size is 14 inch. Claws slightly curved design at the edge feels thinner than the actual size. Machine weight 2.26 kg, equivalent to the average in the 14-inch laptop.

Aspire 4750G quite fully equipped from the HDMI port, VGA, USB 2.0 to the latest USB 3.0 standard. However, your lack of data exchange port high speed eSATA. Because it owns the big screen large enough for your own optical drive read / write DVD.

Thermal vents on the left side of the machine are arranged in two rows split the middle connector instead of lying close to the edge as much as current models. To ensure the connection is not ranked too tight, SD memory card reader is given front row next to the factory signal lights.

Aspire 4750G keyboard equipped with the Acer tradition. Because using 14 inch screen, so no separate number pad side. Unfortunately, to create beauty and personalities to the navigation keys of the machine is slightly smaller. Furthermore, this model does not have the multimedia keys separate off the top.

Design of the Acer keyboard feels great depth but rather key fact used for that short little trip down. The keys feel slightly lighter and will need more time to manipulate the machines used if the user is using the familiar desktop keyboard like Logitech or Misumi. In return, the distance between the keys just to help not occur type the wrong keys.

Contrary to the fingerprint area with floating vein same outer shell, the machine's touchpad to the glossy plastic surfaces. This design slightly "missed the point" a bit by using adhesive feeling vulnerable, especially when using longer have sweaty hands.

Continue using PCMark Vantage program to assess the overall strength, Acer Aspire 4141 reached the level of not really outstanding compared to other laptops even lower price. As Toshiba's C600 also scored over 3,900 points with similar evaluations.

To use a discrete graphics card from Nvidia, 4750G reach 5,092 points when evaluated by the program 3D Mark 06. The level is higher than the average of more than 2,000 points in the same processor but use the integrated graphics chip instead of discrete graphics.

Continue to use the program to evaluate Cinebech 5.11 processor and try OpenGL. The results achieved with the 1.91 processor and graphics point quite well with 15.43 frames per second.

Aspire 4750G Hard Drive that is used by Hitachi 500GB production rate of 5,400 revolutions per minute. In fact the data read speed rating is 62.1 MB / sec, equivalent to an average of 60MB/sec in the common drive speed 5400 rpm / min.

Radiator.

 

 

Acer Aspire 4750G can heat at fairly, air temperature does not rise too fast and when to run full-load CPU 100% more than half an hour (in the picture above). Meanwhile, if you tried to run 3D Mark continuously for about an hour, the machine heats up quite a lot, but the use of the legs is still possible. The hottest areas are the side heat sink and the left slot of the keyboard, touchpad.

Battery.

Aspire 4750G using the 6 cell battery 48 Wh capacity comes. To fully charge from 7% to disable the entire machine takes about 3 hours 40 minutes while normal use.

These figures show that the battery of the Aspire 4750G is quite good, may be used both discrete graphics, but the battery life equivalent, and even more models equipped with second generation Intel Core i5 not have left the card.

Sound.

Equipped with Dolby sound systems Advance Audio, the Acer laptop has a higher sound quality than the cheaper models but still not comparable with the entertainment laptop in range 600 to 700$  as of HP or Asus.

Chassis made of aluminum alloy to ensure while the hand area  magnesium alloy helps prevent collisions and improve heat dissipation capability, making it comfortable to use. Dell laptop with a weight of not greater than some 13 inch models the lightest on the market of about 1.3 kg but more powerful configurations and price "pleasant" than many.

Vostro hinge design of the V13 is very similar line of Dell XPS and Adamo with the bulge a little. Using zinc to produce material, joints appear to be quite sure and manufacturers introduced withstand the impact force.

Connectors and webcam.

Connectivity on the V130 has been upgraded quite significantly V13 predecessor a year ago. Machine increase the number of USB ports on the two and a HDMI port with USB / eSATA combo, LAN and VGA.

This result 3MB/giay faster than average and faster than about 0.5 MB / sec compared to a sample other ultraportable 13-inch screen is the Toshiba Portege R700. However, there are slightly longer startup time to one minute 46 seconds with operating system Windows 7 Professional.

Using the integrated graphics chip Intel HD Graphics, V130 achieve 3D Mark 1147 points with 06 while the V13 is only achieved when using chip 554 4500MHD GPU. However, the V130's score is not impressive when about 200 points less than the average score on the ultra portable laptop now. test World of Warcraft gaming system running at 13 frames per second with a resolution of 1366 x 768 pixels with High Quality settings.

V130 using wireless card Intel WiFi Link 5100AGN wireless card. At a distance of nearly 5 meters from the broadcast Wi-Fi, data transfer speed of the machine is 25.6 Mb / sec. Meanwhile, at a distance of 15 meters, the rate drops to 15.7 Mb / sec.

Part 3: Radiator, battery, audio

Sound

Because entertainment is not the primary goal should be the speaker on the V130 for quality only average. Large volume of the machine, but the bass is not clear and can not make sense "enough" for users. When you turn the volume level of 100% in both media player and Windows, although difficult to detect but can still sound a bit shy even on high-quality music files.

Duration battery

In testing web surfing, music playback, wi-fi enabled, turn on volume and screen brightness at about 50% the machine can run continuously for approximately 3 hours.

Heat dissipation capability

The thin laptop is often not appreciated by the ability to heat the space inside the limit is difficult to escape the heat. However, the Vostro V130 is the first model of Dell technology cooling cycle Hyperbaric Cooling with outdoor air suction into the machine to cool the components instead of just pushing hot air through the radiator gap as the normal.

Testing a video player Full HD resolution in about half an hour at room temperature about 22 degrees C, the machine's touchpad has measured temperature is 25 degrees C, radiate more heat between the keys G and H keys are about 31 degrees and the average temperature in the entire bottom may be 32 degrees. With this temperature, the user can comfortably use even on both feet without feeling uncomfortable. Parameters do indeed show that V130 with a new cooling technology makes cooling more impressive than the V13.

This design is not sticking your fingerprint and especially suitable for business users do not like the "polished" as many current mid-range laptop.

Tecra R840 has many similarities to the R830 design from the silver hinge, the gateway to the cooling system and keys. Most obvious distinction between the two models is R840 14 inch big screen while the R830 is 13 inches. Outside of the R830 is also brushed aluminum instead of horizontally so as R840.

Tecra R840 is the most lightweight laptops Tecra line current.

With hardware like this, this model achieved 4.7 points (get low score by clicking the graphic capabilities) by the system when the spots on the Windows Experience Index Windows 7 Professional (32bit). On a scale of detail, to reach 6.9 point processor, RAM memory is 5.5 points while the 54.7 graphics capabilities for gaming and graphics point to reach 6.1 points.

Continue using PCMark Vantage program to assess the overall strength, reaching R840 Tecra 4682 points, no less than a model using second-generation Core i7 chip, discrete graphics about nearly 7,000 points.

Do not use discrete graphics, but rather by the integrated graphics chip. However, the chip is used in conjunction with Intel Core processor should i second generation with 3D Mark 06 score is pretty impressive, reaching 2367 points. Current models use integrated graphics chip Intel Core i3 of the second generation on the market around 1,400 points in the same form i5 a previous generation is only about 1,500 points.

Continue to use the program to evaluate Cinebech 11.5 microprocessors and try OpenGL. Results achieved with 2.43 point processors and graphics cards with 4.19 frames per second.

R840 Tecra hard drive that is using a 500GB 7,200 revolutions per minute. In fact the rate of reading data averaged 81.3 MB / sec, higher than average in the hard school 60MB/giay speed 5400 rpm and approximately the same compared to the hard drive speed today.

Toshiba integrated a lot of systems management features similar to the R840 models for other entrepreneurs. PC Health Monitor Manager can manage many features such as battery, the level of "harden" battery, CPU temperatures, mail or fan speed.

In addition, the R840 can also shock resistant hard drive. When the appliance detects sudden changes in position or powerful, automated alerts and the speed down to limit the ability to corrupt or lost data. This warning can also turn off operation only on the taskbar.
