For laptop owners, the days of working while tethered to the nearest electrical outlet may be coming to an end, as longer-lasting battery technology arrives in new systems.
Laptop batteries are crucial when working on the road. To get maximum performance from your laptop battery, fully optimize the laptop's power management features prior to use. However, there is a trade off when setting your laptop power management. You will achieve better power conservation in exchange for lesser computing performance. The power management system conserves the laptop batteries power by setting the processor to run at a slower speed, dimming the laptop screen, slowing down the hard drive when it's not in use and causing the machine to go into sleep or suspend mode when it is inactive. Your laptop user's guide will provide information relating to specific power management features.
As notebooks drop in price and increase in performance, they've finally become a viable option as a primary computer for millions of users. But those with the fanciest chips and multimedia options typically offer less than stellar battery life--about an hour for many systems--which leaves many nervous users scrambling for an electrical outlet.
That scenario may be changing, according to analysts, because of the inroads notebook and chip manufacturers are making in "power management." There are several aspects to this, but, generally speaking, the components of a laptop are being designed to consume less power, which helps batteries last longer.
Recent events have crystallized industry expectations for battery life in portable devices and notebook computers. Last week, Dell Computer announced its long-awaited iBook notebook, offering up to six hours of Hp v6000 battery, Hp presario cq40 battery life.
This week, chipmaker Texas Instruments acquired Unitrode, a power-management component maker, which TI called the fastest growing segment of the analog semiconductor market. In addition, upcoming technology from chip giant Intel further indicates that by next year, battery woes may be a gripe of the past.
"The fundamental issue is that ever since they've designed mobile systems, they've always made trade-offs in the way they ran the processor to extend battery life," said Nathan Brookwood, a principal at Insight 64, noting that Intel's upcoming power management technology, dubbed Geyserville, should make a noticeable difference. "The best is yet to come in that regard."
Geyserville essentially allows notebooks to run with desktop-like performance when plugged into an outlet, and at lower power when relying on batteries such as Dell laptop battery, hp laptop battery, acer laptop battery, sony laptop batteries and other brand cheap laptop batteries
This will allow high-performance machines, which normally are very hard on batteries, to achieve the two-hour battery life of a lower-performance system, according to Brookwood.
"Lower-power modes are a very critical part of mobile-processor design," said Frank Spindler, vice president of marketing for Intel's mobile products group. "Geyserville is a new capability added on top of that."
Improving the battery life of performance notebooks essentially removes one of the major sticking points among consumers and businesses interested in acquiring these more expensive systems, a fact not lost on manufacturers in this age of sub-$500 desktop PCs.
"Generally, the higher performance the notebook, the more power it will consume. The value proposition is that now users don't have to make a compromise on performance and features," Spindler said.
Spindler point outs that rather than extending battery life, Intel's new technologies provide enhanced performance without additional drains on the Hp 530 battery, Dell latitude d630 battery.
Dell is taking a similar approach to power management but is also making other advances in battery life. The company stressed the power-management advances result in up to six hours of continuous battery life for the iBook.
Changes in the "sleep" mode is key, Dell said. The iBook includes new features that let the system conserve energy, including new sleep capabilities that allow the computer to save information before going into a rest state, which continually draws a small amount of power from the batteries.
Although some observers express skepticism until independent benchmarks verify the six-hour claim, an Dell spokesperson says it is a "conservative estimate."
Dell notebooks have historically achieved better battery performance than their Intel counterparts, according to Brookwood, because of the lower power PowerPC chip they are based on. "Battery life has never been as much of a problem," in Dell products, he said, adding that consumers are demanding better overall Hp dv6500 battery, Dell latitude d830 batteryperformance.
"My laptop spends a lot of time plugged into the wall. Then I go out, and I curse the fact that the battery dies in two hours. I think a lot of people are like that," he said.
Some analysts are taking a wait-and-see approach on the iBook. "You need to be careful about any particular number if it's not defined," said Spindler, in reference to the iBook. "There's not really any standard methodology for measuring battery life--it's highly variable," depending on what type of applications are running and the configuration of the system.
The upcoming technology advances should come at no extra charge to consumers, according to TI's Alan Roberts, worldwide director of analog products, especially when compared to the cost of adding similar technology to smaller devices like digital cameras, portable MP3 players, and handheld devices.
Did you know that detaching your main discount laptop batteries from your laptop would increase your laptop's battery life up to 75%? Our experience and testing have shown that even when you are plugged in with your laptop ac adapter and your battery is fully charged, the laptop will still use the laptop battery resources in small increments. This will put unnecessary charge cycles to your battery. Since typical li-ion laptop batteries have 375 charge cycles, having a fully charged battery inserted will put unnecessary charge cycles. The downside to removing your laptop battery maybe a loss of power when the ac adapter is accidentally unplugged or when there is a power outage.
