Holiday Laptop Shopping Tips


Many people choose to buy a laptop online, where shoppers can find a wider selection and typically lower prices. That's fine, but you really shouldn't buy a new computer sight unseen if you can avoid it. Write down the names of some of the models you're interested in, along with a few notes about why they caught your eye, and head to your local big-box electronics store. See if the store has display units of any of the systems you're considering, or at least very similar models by the same manufacturer. Try the keyboard--can you type easily on it? Is the touchpad a pain to use? Does the screen look good? If the laptop you want to buy has a glossy screen,longe battery life,inspiron 1520 batteryvostro 1500 battery look at other models with glossy screens and determine whether your gift recipient might prefer that look over a matte, antiglare finish.

Pick up the laptop you want to buy, and evaluate its heft. Close the lid and see if the size is something that the recipient can fit into their chosen bag (don't actually put it in a bag, of course, unless you want security all over you). Bear in mind that many display notebooks in stores have the battery removed, which makes them seem considerably lighter.

Once you have a feel for your desired laptop (or a very similar one), you can go back home and buy online with confidence. If you're buying in a brick-and-mortar store, you might want to ask if the retailer has any sales coming up, or at least call around to different stores to see which one has the best price. Or use your mobile phone to check the latest prices online, and see how competitive the in-store price is. The store you prefer might even match the price of a local competitor.

Need More RAM? Do It Yourself

Let's say that the laptop you want to buy comes with 2GB of RAM but is expandable to 4GB,9cells inspiron 1520 batteryvostro 1500 battery. You might be able to save some money if you upgrade the laptop's RAM yourself instead of buying the 4GB option from the manufacturer. See how much more it costs to buy the machine with 4GB, and compare that with buying the RAM separately and installing it (the task typically requires removing only a couple of screws and about 5 minutes of your time--it's easy to do on most laptops today).

Naturally, you'll have to do a little homework first. Make sure that the laptop has an empty RAM socket (ask a sales rep if you're not sure), and find out what type and speed of RAM you'll need. If all of this seems intimidating, it's okay--just buy the system with the RAM upgrade. Your time and frustration are worth only so much.

Know Which Accessories to Get
If your gift recipient will need a spare battery, select one that is specifically made to work with the particular model of laptop. It's not a bad idea to buy the battery right when you purchase the PC--especially if you're buying online, where an extra battery may be offered as an option. Use caution if you buy an aftermarket battery from a manufacturer other than the one that made the laptop: Some of these batteries are priced really well but store less energy. Read user reviews and comments about third-party batteries,gk479 , fk890 carefully to make sure you're not sacrificing battery life to save a few bucks.

As for external optical drives, don't feel obligated to buy one from the manufacturer of the laptop. External optical drives that connect via USB are generally universal, so look around for a good price.

Among other laptop accessories, consider buying a small, wireless travel mouse. Even the best touchpad can be a nuisance at times, and you can find tons of compact,inspiron 15 battery, inspiron 1525 battery battery-operated wireless mice that are specifically designed to travel with a laptop. If your gift recipient wants to use a laptop mouse on an airplane, however, be aware that wireless versions are forbidden--they'll need a wired model for use in-flight.

You can probably avoid spending cash on a specialized laptop bag or carrying case, which retail stores often mark up quite a lot. Unless you encounter a great bargain, or you find a special case made just for the unusually large or small laptop you're buying and the gift recipient would love to have it, bide your time. Buying a really great bag is a whole other process in itself--don't get something the person will hate just because it's expedient and convenient.

If the salesperson tries to push other folderol on you, like screen wipes, blank discs, and extra cables, just say "no thanks." These items almost always carry a high markup in stores, and you're usually better off buying them online if you don't think you need them right away.

When In Doubt, Go Faster

If, after going hands-on with a few laptops, you're just not sure whether your gift recipient needs a faster processor, dedicated graphics, or more RAM, take the leap. Nobody ever complained that their laptop was too fast, but spending the next couple of years working on an annoyingly sluggish laptop will get old in a hurry. Expect software to become ever more resource-hungry over time, too; the applications that the laptop's new owner will use next year will likely be a little more demanding than what they use today. And if they have an HDTV or they're considering buying one in the future, an HDMI output on the laptop may come in handy.

Laptops are a little different than most consumer electronics and desktop computers in that they're, well, highly portable. People tend to throw them into bags, toss them around, accidentally knock them off tables, leave them to be poked and prodded by kids, and put them on the kitchen table, begging to be victimized by a horrific spill. Know your gift recipient and the environment where they'll use their laptop. If you think they have a high probability of destroying their laptop inspiron 15 battery, inspiron 1525 battery within a couple of years, you might want to consider the extended warranty. (When we last surveyed readers on their satisfaction with extended warranties, we found that consumers who purchased them were very satisfied.) Also, laptop theft protection plans may be a good idea for college students, who have their laptops lost or stolen with alarming regularity.

Cycle Battery life at elevated charge voltages

Chargers for cellular phones, laptops and digital cameras bring the Li-ion battery to 4.20V/cell. This allows maximum runtime, and the consumer wants nothing less than optimal use of the battery capacity. The industry, on the other hand, is more concerned with longevity and prefers lower voltage thresholds. Satellites and electric vehicles are examples where longevity is important.

We have limited information by how much lower charge voltages prolong battery life; this depends on many conditions, as we have learned. What we do know, however, is the capacities. At a charge to 4.10V/cell, the battery holds a capacity that is about 10 percent less than going all the way to 4.20V/cell. In terms of optimal longevity, a charge voltage limit of 3.92V/cell works best but the capacity would be low. Besides selecting the best-suited voltage thresholds, it is also important that the inspiron 1520 batteryvostro 1500 battery does not stay in the high-voltage stage for a long time and is allowed to drop after full charge has been reached.

The voltage threshold of commercial chargers cannot be changed, and making it adjustable would have advantages, especially for laptops as a means of prolonging battery life. When running on extended AC mode, the user would select the “long life” mode and the battery would charge to only, say, 4.05V/cell. This would get a capacity of about 80 percent. Before traveling the user would apply the “full charge mode” to bring the charge to 4.20V/cell. This saturation charge would take about an hour and would fill the inspiron 1520 batteryvostro 1500 battery to 100 percent capacity.

Realizing the stress on the battery, some laptop and cellular phone manufacturers choose an end-of-charge voltage that is less than 4.20V/cell. A slightly larger pack compensates for the reduced runtime. Another option to extend battery life is removing the pack from the laptop when running on the power grid. The Consumer Product Safety Commissionadvises the public to do this out of concern for overheating and causing a fire. Removing the battery has the disadvantage of losing unsaved work on power failure.

Heat buildup is always a concern and running a laptop in bed or on a pillow may contribute to this by restricting airflow. Not only will heat stress electronic components, elevated temperature causes the electrodes in the battery to react with the electrolyte and this will permanently lower the capacity. Placing a ruler or other object under the laptop to increase floor clearance improves air circulation around the enclosure and keeps the unit cooler.

The question is often asked: Should I disconnect my laptop from the power grid when not in use? Under normal circumstances this should not be necessary because once the lithium-ion battery is full, a correctly functioning charger will discontinue the charge and will only engage when the inspiron 15 battery, inspiron 1525 battery voltage drops to a low level. Most users do not remove the AC power, and I like to believe that this practice is safe.

Everyone wants to keep the battery as long as possible and use it in a way that is least stressful. This is not always feasible. Sometimes we need to run the battery in environments that are not conducive to optimal service life. As a doctor cannot predict how long a person will live based on diet and activity alone, so also does the life of a battery vary, and it can always be cut short by an unexpected failure. Batteries and humans share the same volatility.

To get a better understanding of what causes irreversible capacity loss in Li-ion batteries,inspiron 15 battery, inspiron 1525 battery, several research laboratories* are performing forensic tests. Scientist dissected failed batteries to find suspected problem areas on the electrodes. Examining an unrolled 1.5-meter-long strip (5 feet) of metal tape coated with oxide reveals that the finely structured nanomaterials have coarsened. Further studies revealed that the lithium ions responsible to shuttle electric charge between the electrodes had diminished on the cathode and had permanently settled on the anode. This results in the cathode having a lower lithium concentration than a new example, a phenomenon that is irreversible. Knowing the reason for such capacity loss might enable battery manufacturers to produce future batteries with longer life spans.

Power loss through Protection Circuit
Besides common aging, a Li-ion gk479 , fk890 battery can also fail because of undercharge. This occurs if a Li-ion pack is stored in a discharged condition. Self-discharge gradually lowers the voltage of the already discharged battery and the protection circuit cuts off between 2.20 and 2.90V/cell. Some chargers and battery analyzers (including those from Cadex) provide a wake-up feature, or “boost,” to re-energize and recharge these seemingly dead Li-ion batteries.

What Causes Lithium-ion batteries to Old

The lithium-ion battery works on ion movement between the positive and negative electrodes. In theory, such a mechanism should work forever, but shelf life, cycling and temperature affect the performance. Because batteries are used under many demanding environmental conditions, manufacturers take a conservative approach and specify a inspiron 1520 batteryvostro 1500 battery life between 300 and 500 discharge/charge cycles. Life cycle testing is easy to measure and is well understood by the user. Some organizations also add a date stamp of three to five years; however, this method is less reliable because it does not include the type of use.

Figure 1 illustrates the capacity drop of 11 Li-polymer batteries that have been cycled at a Cadex laboratory. The 1500mAh pouch cells were first charged to 4.20V/cell at 1C rate (1500mA) and allowed to saturate to 0.05C (75mA) as part of full charge procedure. The batteries were then discharged at 1500mA to 3.0V/cell, and the cycle was repeated.

Figure 1: Capacity drop as part of cycling. A pool of new 1500mA Li-ionbatteries for smart phone istested on a Cadex C7400 battery analyzer. All 11 pouch packs show a starting capacity of 88–94 percent and decrease in capacity to 73–84 percent after 250 full discharge cycles (2010).

Courtesy of Cadex

Designed for a smart phone, the packs were already a few months old at time of testing and none of the batteries made it to 100 percent. It is common to see lower than specified capacities and shelf life may have contributed to this. Manufacturers tend to overrate their batteries; they know that very few customers would complain. In our test, the expected capacity loss was uniform over the 250 cycles. All sample batteries performed as expected.

Similar to a mechanical device that wears out faster with heavy use, so also does the depth of discharge (DoD) determine the cycle count. The smaller the depth of discharge, the longer the battery will last. If at all possible, avoid frequent full discharges and charge more often between uses. If full discharges cannot be avoided, try utilizing a larger battery. Partial discharge on Li-ion is fine; there is no memory and the battery does not need periodic full discharge cycles other than to calibrate the fuel gauge on a smart inspiron 1520 batteryvostro 1500 battery.

A partial discharge reduces stress and prolongs battery life. Elevated temperature and high currents also affect cycle life.

Specifying battery life by the number of discharge cycles is not complete by itself; equally if not more important are temperature conditions and charging voltages. Lithium-ion suffers stress when exposed to heat and kept at a high charge voltage.

Elevated temperature is anything that dwells above 30°C (86°F), and a high voltage is higher than 4.10V/cell. When estimating longevity, these conditions are difficult to assess because the inspiron 15 battery, inspiron 1525 battery state is in constant flux, and so is the temperature in which it operates. Exposing the battery to high temperature and being at full state-of-charge for an extended time can be more damaging than cycling. Manufacturers do not like to talk about these environmental conditions and release information only in confidence when so requested.

In this essay we do not depend on the manufacturer’s specifications alone but also listen to the comments of users. BatteryUniversity.com is an excellent sounding board to connect with the public and learn about reality. This approach might be unscientific, but it is genuine. When the critical mass speaks, the manufacturers listen. The voice of the multitude is in some ways stronger than laboratory tests performed in sheltered environments.

Let’s look at real-life situations and examine what stress a lithium-ion battery encounters. Most packs last three to five years, less if exposed to high heat and if kept at a full charge. Table 3 illustrates capacity loss as a function of temperature and state-of-charge. One can clearly see a performance drop of recoverable capacity caused by environmental conditions and not cycling. The worst condition is keeping a fully charged battery at elevated temperatures, which is the case when running a laptop on the power grid. Under these circumstances the battery will typically last for about two years, whether cycled or not. The pack does not die suddenly but will produce decreasing runtimes as part of aging.

Batteries are also exposed to elevated temperature when charging with wireless chargers. The energy transfer from a charging mat to the portable device is 70 to 80 percent and the remaining 20 to 30 percent is lost mostly in heat. Placing a cellular phone on the heat generating charging mat stresses the battery more than if charged on a designated charger. We keep in mind that the mat will cool down once the inspiron 15 battery, inspiron 1525 battery is fully charged. Read more: Charging without wires.

Equally stressful is leaving a battery in a hot car, especially if exposed to the sun. When not in use, store the battery in a cool place. For long-term storage, manufacturers recommend a 40 percent charge. This allows for some self-discharge while still retaining sufficient charge to keep the protection circuit active. Finding the ideal state-of-charge is not easy; this would require a discharge unit with an appropriate cut-off. Users should not worry too much about the state-of-charge; a cool and dry place is more important.

The voltage level to which the cells are charged also plays a role in extending longevity. For safety reasons, most lithium-ion cannot exceed 4.20V/cell. While a higher voltage would boost capacity, over-voltage shortens service life. Figure 4 demonstrates the increased capacity but shorter cycle inspiron e1505 battery , inspiron 1501 battery life if Li-ion were allowed to exceed the 4.20V/cell limit. At 4.35V, the capacity would increase by 10 to 15 percent, but the cycle count would be cut in half. More critical than the extra capacity is reduced safety, which would be the results of a higher charge voltage.

Maximize Laptop Battery Life

Most laptop batteries last 18-24 months with average use. This is equivalent to 500-800 charging cycles. Average use of a battery will eventually drain the battery’s ability to hold a charge or there may be some adjustments that you can make to get better performance from your battery. However, if your battery is old and is getting less than half of it’s original run-time, then it may be time for a new laptop battery. If you use your laptop battery everyday, use it for gaming, video streaming and are on WiFi constantly, the laptop will drain the battery run-time and over all life much quicker.

Keep your Batteries Clean

Cleaning dirty battery contacts with a cotton swab and alcohol will help maintain good connections between inspiron 15 battery and the electronic device.

Exercise the Battery

Condition the battery at least once a month. If your inspiron 15 battery has not been used for a long period of time, perform the new battery break in procedure described above (condition).

Laptop Battery Storage


NiCad, NiMH and Li-Ion batteries self-discharge during storage Batteries need to be broken in before use. If you don’t plan on using the battery for at least a month or more, the battery should be stored in a cool dry place. Do not leave the inspiron 15 battery inserted in the laptop for long periods of time with the AC/DC adapter plugged in constantly charging the battery. Not only will this reduce the battery’s life, it can over charge the battery and damage the laptop.

Condition New Batteries

New laptop batteries come in a discharged condition and must be fully charged before use. It is recommended that you fully charge the battery to 100% and let the laptop battery discharge completely on its own. Repeat this procedure 3-4 times to break in the battery and so each battery cell can reach it’s full charging potential. Then condition or exercise the battery at least once a month. Li-Ion battery need only be drained to about 40%, not a full discharge for monthly maintenance, however constant shallow charges should still be avoided. Sometimes it’s not conditioning that the battery needs, but a battery recalibration. Constant shallow charging will confuse the battery and it may need to be re-calibrated. For more information on how to recalibrate your battery visit this link. BIOS Says to Recalibrate My Laptop Battery.

Avoid Memory Effect

Keep your laptop battery healthy by fully charging and then fully discharging it at least once a month. Li-Ion batteries do not suffer from the memory effect, but they too still need conditioning at least once a month with a discharge to about 40% and should not be overcharged.

Remove Battery when Using AC/DC Power Source

Laptop batteries are in constant charge and discharge state when you have the AC/DC adapter plugged into the computer and using the computer with the inspiron 1525 battery installed. Removing the battery while using the AC/DC adapter will help prolong the life span of the battery since most last 500-800 charging cycles or 18-24 months.
