New Laptop Battery

By Khanh Huynh

If you are wondering how long your new laptop battery will last, here are a few things that will give you more insight on the topic.
It is difficult to determine the run time of new laptop battery. The life time of the battery depends on how much power the components of the laptop demand. The parts that drain extra battery, and reduce the run time of new laptop battery, are the hard drive, the monitor and a few other accessories. The other factors that affect the life time, or the run time, of your new laptop battery include the design of the laptop, and the number of hardware that is plugged into your laptop, through its USB ports.
Usually a new laptop battery runs at least as long as your old battery did, when you bought it for the first time. And at times, this battery may run even longer. Small electronic devices, laptops and note books use lighter batteries, and they are defined by the volts, amperes or mill amperes. Did you know that 1 ampere is equal to 1000 milli-amperes? Well, that is just some added information. In order to be able to figure out the life time or the run time of your new laptop battery, you will have to multiply the volts and the amps.
People determine it in such a way that higher the volts, the more your watt hours, but this can vary as it still depends on the amps. To find out the watt hour usage of your new laptop battery, all you have to do is look for it in the user manual of your laptop. There you will be able to find all the specifications of your laptop. A lot of people do not like to read their manuals thinking that they do know everything there is, to know about their laptop. But there are important things that you may not know, which you may end up doing, and in turn, it will shorten the life of your new laptop battery or the life of your laptop itself. It's better to be safe than sorry.
The more programs or peripherals you add in your laptop, the slower the run time becomes. The other harmless things that reduce your battery life are the games, the Wi-Fi and the video streaming. The watt hour that comes on your laptop does not include all these things.

Acer Aspire Timeline 1810TZ This version of the 1810T offers good performance and long battery life for a reasonable price.

by Michael A. Prospero on April 25, 2010


Like its close relative, the 1810T, the Acer Aspire Timeline 1810TZ offers nearly double the power of netbooks while still delivering all-day battery life. At $579, this 11-inch machine isn’t cheap, but for about $180 more than a premium netbook you’re getting a dual-core processor, 4GB of RAM, and a relatively large 320GB hard drive. Plus, the 1810TZ lasts nearly 9 hours on a charge. While we’re not fans of the overly glossy lid, this is one compelling ultraportable.
Design

Not surprisingly, the Aspire Timeline 1810TZ looks the same as the Timeline 1810T and 1410; while at 11.2 x 8 x 1.2 inches it shares the same dimensions as its predecessors, it’s a slightly lighter 3 pounds. Our review unit had a glossy black lid with Acer’s metal logo impressed in the upper corner, and it picks up fingerprints fairly easily. The deck is a silver plastic that’s a decent simulacrum of brushed aluminum, and is offset by the matte black keyboard and glossy black bezel.

Thankfully, the 1810TZ’s six-cell battery does not bulge out the back. Instead, it bumps out of the bottom, tilting the system at a slight downward angle towards the user.
Heat

After playing a Hulu video at full screen for 15 minutes, we measured the temperature of the 1810TZ: the touchpad and the area between the G and H keys was 82 and 88 degrees Fahrenheit, respectively, and the middle of the undercarriage got as hot as 99 degrees. That last temperature is almost a cause for concern; we consider anything over 100 degrees to be too hot.

Best Smartbook: Lenovo Skylight LAPTOP's Best of CES 2010

from laptopmag.com
The breathtakingly thin, beautifully rounded Skylight looks like it's on loan from the future. This device, designed to turn on instantly and provide always-on AT&T 3G connectivity, measures only 0.7 inches thick and weighs under 2 pounds. Beneath its attractive exterior lies something completely new: a Qualcomm Snapdragon processor and flash memory run Lenovo’s Linux-based Skylight  OS, which allows you to easily surf the Web, access social networking, send e-mail, and edit photos through an attractive and simple widget-based interface. Available later this spring for $499 (and presumably cheaper with a two-year contract), this smartbook features a 10-inch display, a full-size keyboard, and up to 10 hours of battery life.

Best in Show: Intel Core i5 Processor LAPTOP's Best of CES 2010

his year's CES was dominated by products featuring the new 2010 Intel Core Processor family. The most outstanding member of this family by far is the Core i5, which brings high-end peformance to mainstream notebooks. We had a chance to review our first Core i5 notebook this week, and we were very impressed by the chip's ability to multitask and perform everyday chores at higher speeds than its Core 2 Duo predecessors. In addition to using Intel's 32-nanometer Nehalem architecture, Core i5 chips contain several innovative features. Hyper-threading allows the processor's two physical cores to run two threads each, dramatically improving the performance of multithreaded apps such as video editors, photo processors, spreadsheets, and high-end games. Turbo Boost allows Core i5 to increase its own clock speed, effectively overclocking itself to speed up processor-intensive tasks. And, for the first time, Intel's graphics chip and memory controller have been integrated into the processor, allowing for better power management, smaller systems, and the ability to amp up the graphics speed as needed.

How Much RAM Do You Need?

A simple RAM upgrade could make your laptop perform like a champ.

If the CPU is the brain of a notebook, constantly performing complex calculations, RAM is the lungs. Pack in enough memory, and your notebook will breathe easy as you speed through games, spreadsheets, and other applications. A lack of RAM, on the other hand, will make your notebook asthmatic, panting and wheezing as it sluggishly executes tasks. Conventional wisdom would have you cram a notebook with as much RAM as possible, but just how much impact does adding memory have on a notebook’s real-world performance?

The Gear

On our tests, we used a Gateway P-7808u FX running 64-bit Windows Vista Home Premium as our base machine. We installed 2GB of Kingston 1.06-GHz DDR3 RAM (two 1GB sticks for $35 each), 3GB of Kingston 1.06-GHz DDR3 RAM (one 2GB stick and 1GB stick for $33 and $59, respectively), and 4GB of Kingston 1.06-GHz DDR3 RAM (two 2GB sticks for $59 each). Note: The 32-bit version of Windows will read about 3GB of RAM.
With each upgrade—2GB, 3GB, and 4GB of RAM—we launched four programs using our application open test: Abode Acrobat Reader, Adobe Photoshop CS4, Firefox 3, and Microsoft Word 2007. We also performed our test while stressing the notebook by compressing a 4.97GB mixed-media folder in the background. Then we ran PCMark Vantage, a synthetic test that gauges a notebook’s performance in Vista. We ran each benchmark three times, and took the average for our results.

Performance

With 2GB of RAM installed, our notebook opened Acrobat Reader in 11 seconds, Photoshop CS4 in 26 seconds, Firefox in 5 seconds, and Word 2007 in 7 seconds. The PCMark Vantage score of 4,274 was nearly 500 points higher than the 3,789 desktop replacement average (most systems in this category contain 4GB of RAM). Surprisingly, bumping up the RAM capacity to 3GB, and then to 4GB didn’t improve the application open times by a significant margin. The PCMark Vantage scores, on the other hand, jumped 415 and 602 points, respectively.
We noticed a bigger performance delta when we ran our stress tests: Application open times slowed to a crawl with 2GB installed; Acrobat Reader took 61 seconds, Firefox took 1 minute and 24 seconds, Word logged 1 minute and 49 seconds, and the Photoshop CS4 file took a painfully long 2 minutes and 24 seconds. With 3GB of RAM, our machine significantly reduced Firefox’s and Word’s open times (55 seconds and 61 seconds, respectively). Across the board, however, 4GB of RAM had the most impact; it reined in the obscenely long load times and cut stress test times nearly in half (or better in some cases). With 4GB installed, our notebook opened Acrobat Reader in 43 seconds, Photoshop CS4 in 1 minute and 43 seconds, Firefox in 40 seconds, and Word in 44 seconds.

Verdict

Although 2GB of RAM may be good enough for performing such simple everyday tasks as Web-surfing, checking e-mail, and watching video clips, if you need more power for opening large files or heavy-duty multitasking, the extra memory will be worth the splurge.
