HP laptop’s Beats Audio explained in retro video

Ever since Think Beyond, we here at PreCentral have been posting about screen resolution, battery life, Touch To Share technology, along with the host of other details we’re used to focusing on with mobile technology. But times have changed over at the Palm Global Business Unit. HP’s famed scale has brought wonderful new possibilities to the platform, along with a host of interesting tech from their own roster. One great example of this is the migration of Beats Audio to the TouchPad. So far, this feature has been little more than a footnote in most of our coverage, but Beats Audio may actually be a significant product differentiator for HP’s very first webOS tablet. Why? Read on after the break to find out. sumsang r470 battery

So let’s suspend disbelief for a minute. Yes, Beats headphones are manufactured by Monster Cable Products Inc., and come in Dr. Dre, Lady Gaga, Bono, and even Justin Beiber branded varieties. Yes, the Beats brand is fueled at least in part by a hype engine that lives for product placement anywhere from music videos to feature-length Hollywood releases. Does this mean ‘Beats Audio Technology’ is nothing more than marketing? Fortunately for us, the answer is no.

Beats was originally a collaborative effort between famed Interscope Records producer Jimmy Iovine and rap superstar Dr. Dre. As people keenly focused on the production of music, they saw a big opportunity to to make an impact in the mainstream consumer market by focusing on something manufacturers barely considered as an afterthought: Audio quality on computers.

During his speech on February 9th, Iovine cited a long line of medocrity in the music supply chain; Everything from poor bitrate music files on iTunes to chintzy speakers on laptop computers. He noted this was particularly egregious because more and more, computers are our home stereos, and no one is hearing music the way the artists were hearing it in the recording studio.

So how does Beats Audio actually address this? While details are slim in the case of the TouchPad (frankly, were were a little busy asking some other tough questions), we have a clever video from HP that explains what it means to have Beats Audio on an HP (HP Pavilion DM4 battery) laptop.

The big theme here is trying to preserve the audio signal from interference as it moves it’s way down the chain to your ears. This includes attempts to isolate the audio hardware on the motherboard, having a discrete headphone amplifier, separated right, left, and ground audio wires, and even a headphone jack with “no metal parts” to reduce grounding noise. There’s also a Beats Audio-specific sound profile that can be enabled to take advantage of the particular hardware that Beats Audio provides.

So how has this setup on HP’s laptops fared with the critics? Largely quite well. Big names like Engadget, Laptop Magazine, and PC World have had plenty of good things to say about Beats Audio when reviewing laptops like HP’s award-winning Envy series. Even the audiophile community at HeadFi generally seem to have found Beats laptops to provide one of the better out-of-the-box audio experiences. Samsung Q428 battery

So ‘Beats Audio Technology’ actually does have some substance. Could it still amount to one gigantic gimmick on the TouchPad? Sure. Will Beats be the end-all-be-all in home audio for tablet consumers? Probably not. Still, it is reassuring to know that Beats Audio has been more than just clever branding, because it means that audio performance on the TouchPad has a chance of being more than just an afterthought. If nothing else, the hype engine surrounding Beats Audio Technology alone is something our friends at Palm could certainly use when trying to get a foothold in the increasingly competitive tablet market.

E-450 than the i7 strong? APU performance advantage measured Secret

AMD introduced this year, the APU integrated graphics core processor in the notebook platform, APU was the integration of a single entry from the E series is equipped HD6310G to high-end A8 equipped HD6620G, in ascending order of performance, while the corresponding Intel also introduced in the SNB platform, built to fight Core HD3000 graphics card, but the entry-level to high-end Pentium B940 i7, are equipped with HD3000. Both sides will be built-in graphics core, so that ‘set was’ no longer possible. Now we are more curious is the core of both platforms show Who built the stronger. Then we will do a series of comparative tests, give us a clear answer.

Built-in graphics card comparison: AMD E-450 APU vs Core i7

See this comparison, certainly many of my friends would find it ridiculous, because these two processors would not be a price segment, the price difference of several thousand dollars, but I do not want on their overall performance to compare to you , but you want to talk about two separate ‘built-in graphics core .’

AMD introduced this year, most of the A series APU with a strong performance graphics core of entry-level E-350 and E-450 uses a HD6310G and HD6320G, mainstream performance class A4, A6, A8 is the integration of HD6480G, HD6520G and HD6620G.

The Intel side is a core was used in the end, from the low end of the B940 to the top of the i7 Core Fengyun are chosen HD3000 graphics card, so it comes to show the core of the PK is the HD6320G E-450 equipped with the HD3000 contest.

HD6320G parameters compared with the HD3000

Before the war, let us first analyze the AMD E-450 APU’s built-in graphics core HD 6320G and SNB i7 built-in graphics core HD3000 hardware parameters:

AMD E-450 APU built-in graphics card is HD 6320G, which is a remarkable fusion of a single frequency of GPU HD 6310G upgraded version of the core code-named Zacate, using 40nm manufacturing process, with 80 stream processors, 4 raster units, support Directx 11.

Intel HD Graphics 3000 Sandy-birdge based architecture, using the 45nm manufacturing process, has 12 stream processors, two raster units, support Directx 10.1 and other features .

Because both the structure in a different way, it is not simply from the number of stream processors, compared raster unit. To say that the most straightforward way is to compare results from the test.

3DMark06 test comparison

AMD E-450 APU integration monochrome graphics test scores with the B940 compare Core

Since the built-in Core i7 Pentium B940 graphics and built-in Core graphics are identical, are HD3000, so we selected the same as the entry-level Intel Pentium B940 and AMD E-450 APU for built-in graphics card comparison, this CPU performance difference between the two would eventually integrated graphics test results will be less impact from the above chart you can see AMD E-450 APU with HD6320G strong performance slightly better, in the main HDR/SM3. 0/SM2.0 graphics rendering, HD6320G have achieved an advantage, but some of the CPU logic operation has lagged behind the Pentium B940, but in the end AMD E-450 APU’s score or pressure over the Pentium B940, view E-450 APU equipped with a single explicit integration of HD6320G graphics performance is indeed a lot stronger than the HD3000′s performance.

From this we can see that the integration of HD6320G the E-450 an advantage in graphics performance, the B940 integrated HD3000 processor performance only to contend with here could not help but think of Intel’s top processor i7 is just the integration the HD3000. just from the integration on the performance of graphics chips, it is not that E-450 is stronger than the i7 it?

E-450 was the integration of a single graphics card than the Core i7′s strong, it is only a theoretical argument aside processors and we actually still need to see the use of overall performance, so we selected the following two sets on the market the most common hardware configuration, AMD A6-3400M APU + HD 6650M and i5 2410M + GT540M a combination of gaming performance comparison test, to see mainstream gaming platform configuration of the game performance in the end.

AMD A6-3400M APU + HD6650M dual-graphics Crossfire mode vs i5 2410M + GT540M graphics card model comparison test game

AMD on the APU graphical advantage is recognized by everyone. HD6320G alone would overwhelm the HD3000, then use the HD6520G of AMD A6-3400M APU to mention the graphics performance, but the core i5 Although performance is not significantly H3000 strong, but with a GT540M will certainly be after independence was greatly improved, A6 + HD6650M can be a combination of advantages it? dell xps m1530 battery

Table of the series APU

Crossfire dual graphics resolution map

Here we have to know is there on the A6 in the same graphical computing tool – Crossfire (dual card Crossfire). APU chip integration of single-fusion was the core of the Radeon with discrete graphics from AMD’s work, both common collaboration for further performance improvement. But we must understand that crossfire system that allows graphics performance is not there the effect of 1 +1 = 2, its function is to allow collaboration between the two operations, increase the graphics computing capabilities, CrossFire at least be able to achieve 1 +1> 1 the effect.

To test the integration with the i5 A6 monochrome graphics authenticity can, we closed the graphics card after a 3Dmark series of software tests in this part of the Intel completely at a disadvantage, because the HD3000 does not support DX11, so I can not run 3Dmark11.

AMD A6-3400M APU dual-graphics Crossfire vs Intel i5-2410M + NVIDIA GT540M contrast

Then we opened a significant independence, APU on a unique platform for CrossFire dual-graphics capabilities, graphical test again. AMD A6-3400M APU equipped with the integration of a single significant HD6520G Crossfire dual graphics with HD6650M be obtained after the 1687 points, far more than the i5 + GT540M combination of 75.91% in 3DMark Vantage or 3DMark 06 test on AMD A6-3400M APU also winning combination. hp elitebook 6930p battery

Measured game

Scores only on the one hand, the majority of the players, the game’s actual experience is more important to our under test is divided into built-in graphics card comparison and exchange of fire and single significant mode of comparison. DX9 game modes are all the test: all 1366×768 screen resolution / default gaming performance while DX10/11 setting of the game are: full-screen 1366×768 resolution / high effects / open vertical sync.

The first is to use the APU was integrated with a single Intel Core Graphics, the two platforms compare the game to run frames.

AMD A6-3400M APU was integrated single Core vs Intel i5-2410M graphics comparison

Support DX11 features let AMD A6-3400M APU’s performance in the game is very strong, in  << dust heterosexual vs. Predator 3>> operation, the use of AMD APU Single core Radeon display frames in the FPS in general significantly ahead on the Intel Core does not support DX11 graphics card.

AMD A6-3400M APU + HD 6650M dual-graphics Crossfire vs Intel i5-2410M + NVIDIA GT540M contrast

Next, we conducted dual-graphics Crossfire AMD APU contrast to Intel i5-2410M + GT540M discrete graphics mode of the game tests, because the <> is a little old game, even on the ‘vertical sync’ after the high-quality pressure on the current graphics card is not great, APU and SNB performance gap between the two platforms is not obvious, are able to run smoothly, APU platform is almost a full frame level.

However, in DX11 games <> <> the game open after effects support, AMD APU platform, Intel processor and comparing the performance gap between the stand alone was significant. Crossfire dual graphics platform in both the APU games have more than doubled the number of frames in the lead. From this point you can also see AMD APU for the latest on DX10, DX11 game support better. dell latitude d830 battery

Summary: Through a series of tests, we get the result of AMD in the graphics performance is indeed extraordinary strength, such as entry-level fusion HD6320G significant performance than a single Core HD3000 graphics card, graphics computing, has a great gaming experience advantage mainstream AMD A6-3400M APU products in the mainstream games have a strong competitive

Repair my Laptop Headphone Jack

Laptop headphone jack repair is a common repair job and can be the result of general wear and tear or a mishap with the jack, what happens a lot is that the headphones are inserted and the plug gets removed roughly or pulled to one side, accidently dislodging or damaging the headphone jack solder points.

This will result in the loss of sound through the laptops internal speakers or through the headphone jack itself.

Depending on how bad the damage is it may be able to be repaired. A technician that is handy with a soldering iron can often resolder the jack in order to repair functionality without too much trouble. Once again if the jack housing or surrounding components have been damaged too much the repair even for the best technician will be fruitless and would result in the board (PCB) that the headphone jack is connected to being replaced.

Here’s where you need to pray that the laptop you have has the headphone jack mounted on a separate daughter or minor board (PCB). Unfortunately if the headphone jack is mounted on the main board you could be looking at big $$ (main boards here in Australia can cost anything from $400.00 – $2500.00).
Please see diagrams below.

Laptop main board with headphone jack.

Laptop minor (daughter) board with headphone jack.

Warranty on this sort of thing is a bit of a grey area and is taken on a case by case basis by most manufacturers and will depend on the repairer’s findings when they inspect the machine.

Some advice is that if you can find somebody who does component level repairs on audio visual or similar equipment with PCB’s of the same detail, they may be able to repair it for you as well (and at a cheaper price, we all know how laptop technicians can charge!), it’s probably a good idea to consult a technician who works a lot on your make of laptop first to get an idea of the problem.

Research exactly what’s involved with your particular laptop headphone jack repair first in order to save yourself some time and money.

Lithium-ion laptop Battery Life and Death

Lithium-ionpacks are expensive, so if you want to make yours to last longer, here are some things to keep in mind:

» Lithium ion chemistryprefers partial discharge to deep discharge, so it’s best to avoid taking the laptop battery all the way down to zero. Since lithium-ion chemistry does not have a “memory”, you do not harm the laptop battery pack with a partial discharge. If the voltage of a lithium-ion cell drops below a certain level, it’s ruined.
» Lithium-ion batteries age as. They only last two to three years, even if they are sitting on a shelf unused. So do not “avoid using” the laptop battery with the thought that the Aspire 4732 laptop battery pack will last five years. It won’t. Also, if you are buying a new laptop battery pack, you want to make sure it really is new. If it has been sitting on a shelf in the store for a year, it won’t last very long. Manufacturing dates are important.
» Avoid heat, which degrades the batteries.

Exploding Batteries
Now that we know how to keep lithium-ion batteries working longer, let’s look at why they can explode. Several news reports in the past six months describe laptop s with lithium-ionthat caught on fire.

If the laptop battery gets hot enough to ignite the electrolyte, you are going to get a fire. There are video clips and photos on the Web that show just how serious these dell vostro 1310 battery  fires can be. The CBC article,”Summer of the Exploding laptop ,” rounds up several of these incidents.

When a fire like this happens, it is usually caused by an internal short in the laptop battery. Recall from the previous section that lithium-ion cells contain a separator sheet that keeps the positive and negative electrodes apart. If that sheet get punctured  dell latitude d830 battery  and the electrodes touch, the laptop battery heats up very quickly. You may have experienced the kind of heat a laptop batterycan produce if you have ever put a normal 9-volt laptop battery in your pocket. It a coin shorts across the two terminals, the laptop battery gets quite hot.

In a separator failure, that same kind of short compaq presario cq42 battery happens inside the lithium-ion. Since lithium-ion batteries are so energetic, they get very hot. The heat causes the laptop battery to vent the organic solvent used as an electrolyte, and the heat (or a nearby spark) can light it. Once that happens inside one of the cells, the heat of the fire cascades to the other cells and the whole pack goes up in flames.

It is important to note that fires are very rare. Still, it only takes a couple of fires and a little media coverage to prompt a recall.

Flagship business notebook compared ThinkPad T420S vs. T410S

In recent years, although in the business notebook market, fashion, portable mobile products have been dazzled us look at the ball, but as a veteran of the business class ThinkPad T Series Pioneer brand is still in its constancy of the classic style of these occupy the peak of the market . It can be said that all of the outstanding ThinkPad design can be found in the T-series products in both the portability, but also become the most popular models are the business crowd.

Recently, we have first to receive a newly released Lenovo ThinkPad T420S notebook. As the T series and mobility in both high-performance flagship product, the new relationship because of the time, we are only in the evaluation of the product in the first performance of the core component of the test. From product design point of view, a new generation of ThinkPad T Series is the biggest change in the size of the product specifications.

ThinkPad T420S with the previous generation products, the biggest difference is the use of a new generation of Sandy Bridge Intel Core platform and NVIDIA recently launched the NVS 4200M graphics card. In line with the graphics processor core within the same time, the platform also excellent for NVIDIA Chi (Optimus) technical support, according to the load status of intelligent 3D applications to call the graphics card, which enables superior graphics performance and longer battery life time. Especially in the solid state drive with a 160GB SSD, the integrity of its platform is expected to be able to significantly improve.

The new ThinkPad T420S so powerful configuration has enough mouth-watering. So in other respects, the aircraft when compared with what the difference before it? Here, we specifically hired the same, SSD solid state drive with the ThinkPad T410S conduct a comprehensive comparison, so that we feel from the details of new models in the design and performance of the unique charm of it.

In terms of materials, ThinkPad T420s Thinkpad heritage of the roof is still the traditional style, T420s for “downsizing” and uses LED-backlit screen, glass, carbon fiber composite material with a magnesium alloy roll cage combination to provide the most efficient protection, which has a long history has been verified.

ThinkPad T420S change the screen size has been a lot of “black fans” who debate the topic, some people even think that their products may be reduced to mediocrity. But the objective point of view, select the 16:9 approach both in terms of cost control, or the needs of the mainstream on the video processing is a good choice. After all, 16:9 panel in cutting efficiency higher than the 16:10 panel.

ThinkPad T410s have all the selling points are reflected on the T420s. Mold specifications ThinkPad T420S biggest improvement is the introduction of high-resolution 16:9 screen design, the best resolution up to 1600×900. More screen width greater T420S keyhole on both sides of the fuselage above the position of the screen left and right hook to make the force more evenly.

In the interface design, ThinkPad T420s introduction of USB3.0 and DisplayPort configuration, and the port layout options in the traditional horizontal layout. Originally designed in such a way as to economize on space within reach for the T420s “downsizing” purposes.

ThinkPad T420S random standard Intel Core i5 2520M processor uses the latest 32nm process technology, the Intel in the early 2011′s native dual-core processor, clocked at 2.5GHz. Compared to the previous generation T410S adopted Core i5 560M processor, although slightly lower, but the frequency dependence in the second generation Turbo Boost Technology up to its maximum frequency is still 3.2GHz, this specification is not lost on Core i5 560M the processor.

ThinkPad T420S notebook nuclear integrated Intel (R) HD Graphics graphics default frequency of 650MHz, although the default frequency do not have much advantage at all, but the graphics card up to the maximum dynamic frequency of 1.3GHz. The T410S with the Core i5 560M provides HD Graphics card could not be done because the real integration of the CPU core, and its efficiency in the implementation of graphics will also be different.

ThinkPad T420S is equipped with NVIDIA NVS 4200M NVIDIA specifically designed for the commercial notebook graphics card, graphics card Geforce GT520M can be regarded as high-frequency professional version. It has 48 CUDA cores, compared with the previous generation T410S NVS 3100M in the core number to two times, support for DirectX 11 features, up to 1GB memory, and raise the operating frequency to 810MHz, Shader frequency raised to 1620MHz .

Comments: Before using the same Intel Core i5 560M processor T410S compared, T420S used IntelCore i5 2520M processor, although the frequency of the core is not much advantage at all, but with Intel’s second generation Turbo technology in CineBench R10 test results and no less than the previous product with even a little improvement. In the graphics area, and its nearly 10,000 points in test scores can meet the needs of mainstream 3D processing.

In PCMarkVantage tests, as two generations of products are used SSD solid state drive with the program, so the hard drive has a higher efficiency in the implementation aspects of the play. The new ThinkPad T420S with Intel Core i5 2520M processor and NVS 4200M graphics card with that platform for an effective overall performance has significantly improved. 12,000 points or more test results also show that the majority of multimedia applications in everyday products completely satisfy customer needs.

The integrated office application environment, ThinkPad T420S also has 15% in performance improvement. The results from the point of view, the four common office applications T420S’s performance is satisfactory, the composite score of 230 points or more, including video creation, and office test the efficiency of the most obvious advantage of children.

Specifications in the previous table, we have seen, ThinkPad T420S random standard Intel Core i5 2520M NVIDIA NVS 4200M plus the product mix of higher power consumption. Materials used in the shell, two generations of a large number of laptops with magnesium alloy, so although the use of materials and auxiliary heat in the body has a strength advantage, but limited to 14-inch mold space, the bulk of its actual effect is still not optimistic.

With the 32nm process technology, the processor with the two products of the overall power consumption is not an exaggeration, compared to ThinkPad T420S laptop working environment in a long time under high load, the C side of the area to the left, the bottom of the processor outlet location and the main outlet of the heat processor volume slightly higher than the previous T410S. However, two generations of products are designed in double-outlet left side and back of the fuselage, so the heat used for most applications the user right-hand little effect. lenovo thinkpad x200 battery

From this comparison, a new generation of Lenovo ThinkPad 420s as the main T-Series models, designed in the mold remained on the previous generation of the classic design, product specifications and details in the display design has changed slightly. While in port and some small details of the layout slightly changed, adding the nowadays more popular USB3.0 interface, but the machine still adhering to the ThinkPad family of excellent quality and precise workmanship of the overall structure.

The core component in the mix, ThinkPad 420s hardware configuration has been fully upgraded. The products selected Sandy Bridge platform with NVIDIA NVS4200M graphics program. In the Intel Core i5 2520M good support, the nucleus and discrete graphics card with excellent, so that the product or whether it is integrated in the daily office processing capabilities are more T410S has improved. lenovo thinkpad t400 battery

Written in the last: As of the end of our test, the media reported a series of ThinkPad CPU deceleration rumors: “high-performance mode the processor will automatically surprisingly reduced to the lowest power mode, and there is now not only in the ThinkPad in the T420 and T520 models have also been found in the same situation. “Perhaps these rumors are not groundless, but in contrast to test the two products are not unusual. Both products work fine and delicate at the same time ensuring full application of the platform to show the performance level, not any so-called reduced frequency of the phenomenon. Therefore, we believe that even if there is reduced frequency of the phenomenon is likely to be also present in the individual or small batches of the above media hype. HP Pavilion DM4 battery
