One of the rare success stories of a tough 2009 in tech, the netbook is set to get an overhaul courtesy of Intel’s Pine Trail technology. Intel released Pine Trail earlier this week, and a few computer makers have announced new netbooks based on it. dell laptop battery The rest will surface at the Consumer Electronics Show in early January. Here’s what to expect from these new netbooks.

Pine Trail is a platform, not a processor, and the details of this new platform have been known since at least May 2009 when Intel held what it termed a “disclosure” (PDF here). It consists of a Pineview processor, which includes both a 45nm CPU with integrated memory controller and a 45nm GPU, the Intel Graphics Media Accelerator 3150, in a single package. Though Intel pairs this with an NM10 Express “chipset,”Dell Latitude D620 Battery, Dell 312-0386 Battery, Dell PC764 Battery, it’s really just one chip (Tiger Point), which functions as a southbridge for I/O. In effect, Intel has shifted from a three-chip solution, such as the Atom N280 with the 945GSE chipset (consisting of a graphics/memory controller and a separate I/O controller hub) to a two-chip solution. Pineview is Intel’s first CPU with integrated graphics, though it will be quickly overshadowed by the launch of the 32nm Arrandale laptop and Clarkdale desktop chips with the same level of integration, which will arrive in a matter of weeks. The advantages of this integration are obvious: it costs less to manufacture, takes up less space and requires less power. (It is also the crux of the escalating legal battle between Intel and Nvidia, which makes its own GPUs and chipsets for Intel-based PCs.)

Intel released three Pineview processors. The 1.66GHz Atom N450 is a single-core processor (two threads) that supports up to 2GB of 667MHz DDR2 memory. The current Atom platform uses slower main memory. The Atom D410 and D510 are both for entry-level desktops (Intel has apparently given up on the term nettops) and run at the same 1.66GHz. The difference is that the D410 has one core and two threads, while the D510 is a dual-core Atom capable of processing four threads simultaneously. Dell Latitude D620 Battery, Both the D410 and D510 support up to 2GB of either 667MHz of 800MHz DDR2 memory (though most coverage has focused on the N450 and new netbooks, PCMag.com tested a whitebox using the D510).

Intel says that there are more than 80 Pine Trail netbooks and entry-level desktops in the works from Asus, Acer, Dell, Toshiba, Fujitsu, Lenovo, Samsung and MSI. Asus was first of the mark, and several sites have posted reviews of the Eee PC 1005PE (links to reviews below). This upgrade has the same basic design as the popular 10-inch Eee PC 1005HA, but with the Atom N450. The Eee PC 1005PE starts at $379 with 1GB of memory, a 250GB hard drive and Windows 7 Starter. Dell announced an update to its Mini 10. The Pine Trail version will start at $299 with Ubuntu Linux (1GB and 160GB hard drive) and $399 with Windows 7. The design is also different–this version is smaller and lighter with a battery that doesn’t jut from the back–and, unlike the Eee PC 1005PE, it will offer an optional, higher resolution (1366 by 768 pixels) display. Fujitsu also announced its Lifebook MH380 Mini-Notebook (Atom N450, 1GB, 250GB hard drive and Windows 7 Starter for $449), and there are rumors of Pine Trail netbooks from HP and Lenovo (which I’m sure we’ll hear about at CES in early January,Dell Latitude D620 Battery, Dell 312-0386 Battery, Dell PC764 Battery, if not sooner). Though Intel is still pushing Moblin, the vast majority of these Pine Trail netbooks will come with Windows 7.

Though there was a lot of talk about Pine Trail giving a boost to netbook performance, and in particular playback of high-quality video, the gains here look pretty modest. That’s not terribly surprising since Intel essentially shifted from the Atom N280, a single-core processor (two threads) running at 1.66GHz to the Atom N450,Dell 312-0386 Battery, also a single-core processor (with two threads) running at the same frequency. Intel says the new graphics core is up to the task of playing 720p video, and that generally seems to be the case though some reviewers had better luck with YouTube HD clips than others. Where Pine Trail really stands out, however, is battery life. With a 6-cell battery, the Eee PC 1005PE was good for anywhere from 8 hours on torture tests to more than 10 hours under typical usage. That’s a compelling reason for owning a netbook.

Since Pine Trail doesn’t change much in terms of performance, the door is open a bit for other chipmakers to come up with ways to speed up netbooks. Intel has been working with Broadcom on a single video decoder chip, the BCM70015 Crystal HD, which will be an option for some netbooks to enhance performance with high-definition video. Meanwhile Nvidia looks set to release a new version of its ION chipset, which will not only bring 1080p video support, but also Blu-ray playback and better gaming performance. Intel execs say this is overkill for netbooks, but Nvidia believes there’s real demand for better performance in this class. At the opposite extreme, I also expect to see lots of smartbook designs using less powerful chips from Freescale, Nvidia (Tegra) and Qualcomm at CES.

This is the time of year for tech predictions, and there is no shortage of netbook prognosticators. Some pundits predict that the fad is over, and netbooks are set to cool off. Others suggest that Intel’s new platform could spark a second wave of rapid growth. My guess is the truth is somewhere in between and netbook unit sales will continue to grow at a decent pace. The new models may be slightly larger than current ones, and laptops using ultra low-voltage (ULV) chips will almost certainly siphon off some sales.Dell PC764 Battery, But ultimately it doesn’t really matter whether you call them netbooks or notebooks. There will continue to be strong demand for highly-mobile computing at lower prices.
Some of the larger laptops are now offering quad-core processors, but most users will be better off with a fast dual-core processor combined with more memory. You may notice that many laptops come with a new type of system memory, DRR3, which is faster and uses less power than DDR2 memory. Most laptops use an Intel chipset with integrated graphics (Arrandale will actually put graphics processor in the same physical package with the CPU) and this has advantages in terms of battery life. But it can’t match either the integrated or discrete graphics from AMD or Nvidia in terms of performance.Dell Latitude D620 Battery, Dell 312-0386 Battery, Dell PC764 Battery, More computer makers are offering solid-state disks in lieu of standard hard drives, but this market has yet to materialize largely because NAND flash remains too costly, though performance has been an issue as well. Microsoft designed Windows 7 to take better advantages of SSDs, so as the price comes down, we may see some pick-up in 2011. But for now, you can ignore them.

Finally several PC makers have started dropping internal optical drives from some larger laptops with displays of 13, 14 or even 15-plus inches to make them thinner and lighter. This is largely a matter of personal preference, depending on how much you travel, and whether you are accustomed to downloading all of your applications and content. Many entertainment notebooks have optional Blu-ray players or burners.

This problem has plagued many loyal users of laptop computers,dell laptop battery including me.

In checking some of the information, recently had the opportunity to consult a professional in an electrochemical Ph.D. and a well-known domestic battery, deputy director of the Institute. Now a number of recently acquired knowledge and experience in writing, to satisfy the reader of you. 　　

Lithium-ion battery cathode material of lithium active compounds are usually composed of negative electrode is a special molecular structure of carbon. Common cathode material for the major components ofLiCoO2, Charging time, added to the battery positive pole of the electric potential to force release of lithium-ion compounds, embedded negative elements arranged in lamellar structure of the carbon. Discharge, lithium-ion from the lamellar structure of carbon precipitation and re-cathode combination of compounds. Lithium-ion movement generated a current. 　　

Although the chemical reaction principle is very simple, but in the actual industrial production, the practical problems need to be considered much more: the cathode material additives required to maintain the multiple charge-discharge activity, the negative electrode material, which needs to design the molecular structure of class to accommodate more lithium-ion; fill in the electrolyte between the positive and negative electrodes, in addition to maintaining stability, but also need to have good electrical conductivity, reducing the battery internal resistance. 　　

Although the lithium-ion batteries little nickel-cadmium battery memory effect,Dell G5266 Battery Dell Latitude CPi Battery, Dell Inspiron 8200 Battery, memory effect of the principle is that crystallization, in the lithium batteries will have little reaction. However, lithium-ion battery capacity after repeated charge-discharge will continue to decline, its causes are complex and diverse. Dell G5266 Battery Is mainly positive and negative changes in the material itself, from the molecular level, the positive and negative electrodes of lithium ion on the hole to accommodate the structure will gradually collapse, plug; from the chemical point of view, is the active anode material is passive, there's the other side to form a stable compounds. Physics will appear on the cathode material gradually falling off, etc., in short, can ultimately reduce the battery charging and discharging process of the free movement of the number of lithium-ion. 　　

Over-charging and over-discharge, lithium-ion batteries will be positive and negative result in permanent damage, from the molecular level, intuitive understanding, excessive discharge of carbon anode will lead to excessive release of lithium-ion and makes it appear lamellar structure collapsed, over - Rechargeable lithium-ion will too hard go into the negative carbon structure, causing some of the lithium-ion can no longer be released. This is why lithium-ion batteries are usually equipped with charge-discharge control circuit causes. 　　

Not suitable for the temperature, will lead to lithium-ion battery inside the reaction of other chemical compounds that we do not want to see, so many of the lithium-ion batteries are being set up between the protective negative temperature-controlled diaphragm or electrolyte additives. In the battery temperature to a certain case, the composite membrane electrolyte membrane hole closed or degeneration, increased battery internal resistance until the circuit, the battery is no longer to heat up, to ensure that the battery charging temperature is normal. 　　

And deep charge-discharge lithium-ion batteries can improve the actual capacity?

Experts clearly told me that this is meaningless.Dell Latitude CPi Battery, They even said that the so-called three full charge-discharge prior to use of "activation" in the knowledge of both of them, Dr. Lane, do not understand this as a need. Why do so many people, however, Dell G5266 Battery Dell Latitude CPi Battery, Dell Inspiron 8200 Battery,after the deep charge-dischargeBattery InformationLane marked capacity would change it? Will be mentioned later. 　　

Notebook computer lithium-ion batteries are generally with the management of chip and charge control chips. Which management chip in a series of registers, there is capacity, temperature,ID, Charge status, discharge frequency values. These values are in use will gradually change. I personally believe that the instructions for use in notebook computers in the "Use a month should put a full-charge" approach to a major role should be is to fix these registers where the wrong value, making the battery charge control and the nominal capacity of the battery match the actual situation. 　　

Charge control the main control chip, the battery charging process. Lithium-ion battery charging process is divided into two phases, constant-current fast charge phase (when the battery indicator light yellow) and the constant-voltage current decreasing phase(The battery indicator light flashes green. Constant-current fast-charge stage, the battery voltage gradually rises to the standard battery voltage, and then transferred to constant pressure in the control phase of the next chip, the voltage will not rise in order to ensure that no over-charge, current battery, along with the gradual weakening of the increase in to0And finally completed charging. 　　

Statistics chip power consumption by recording the discharge curve (voltage, current, time) can calculate the sample battery power, which is what we in theBattery InformationRead insidewh.Value. The lithium-ion batteries in repeated use, the discharge curve will change, if the chip has not been opportunity to once again read out a complete discharge curve, which is calculated out of electricity that is not accurate. So we need to deep charge-discharge to calibrate the battery chips. 　　

Finally, I right battery maintenance view is: 　　

1. No need to ensure that every time a re-release END electric charge; 　　

2. A period of time to do a protection circuit under the control of deep charge-discharge the battery power to amend the statistics,Dell Inspiron 8200 Battery, but it will not improve your battery's actual capacity.

3. A long-term unused batteries, should be placed in the shade in order to weaken its internal self-passivation reaction speed. 　　

4. Protection circuit is also able to monitor the battery self-discharge,Dell G5266 Battery Dell Latitude CPi Battery, Dell Inspiron 8200 Battery, long-term without the battery should be charging to a certain degree of power to prevent self-discharge of batteries in storage in the discharge of excessive lead to excessive damage. 　　

In fact, there is not much to take into account the battery use of attention, in other words is taken into account is not much use. The number of times a cell can use, and perhaps more from the battery itself, differences in the manufacture of individual differences, rather than use. Choose a good reputation of the notebook PC brand, is undoubtedly the future long-life battery one of the guarantees.
