THE LAPTOP BATTERY – UNDERAPPRECIATED BUT CRUCIAL


Humans are excellent at adapting. Since the beginning of time, we have learnt, adapted and evolved. New inventions soon become necessities and we absorb and incorporate these into our daily lives with such ease that they practically become the norm.

Take portable devices for example.  Can you remember the last time you met someone who did not have a phone, PDA or laptop? These are not only the enablers but are also the core components of the support system of our very busy, very mobile lives. Devices like laptop computers have increased mankind’s productivity many folds and the demand for these seems insatiable!

Laptops are at the very centre of this information technology era that we live in today. The rise of laptops in their original mobile format started in the late 1980s. In 1986, battery powered portable computers i.e laptops, had only 2% of the worldwide market share; by 2008, this figure jumped dramatically when more laptops than desktops were sold worldwide. As per Gartner analysts, mobile PCs have been averaging a growth rate approaching 40% during the period 2005-2010. A double-digit growth figure for the mobile PC industry (these include laptops, net books and tablets) continues to be forecasted by Gartner for the period 2011-2015.

With the rise of laptop computers, came the rise of the single most important factor that has made its mobility a reality – the laptopbattery! The laptop computer battery (or as it is sometimes referred to as the notebook battery) is undoubtedly the most important component, the very lifeblood of this modern portable technology. It is the laptop battery that provides power to our laptop computer when we are on the move. Regardless of the hardware specs, or the software you have loaded on your laptop, if the battery fails and you don’t have a power socket nearby – you stop being productive.

Despite its crucial role, the laptop battery is often underappreciated or overlooked by both customers as well as laptop computer manufacturers. While we are all intent in knowing the speed of the processor, or the size of the memory, or the hard drive space – most folks don’t pay too much attention to the specifications of the laptop battery such as its chemistry, its capacity, the number of cells  (Cells are electrochemical units that store power when charged and release this electrical charge when needed later) it uses or even the brand of the cells utilized by the laptop battery pack – all of these elements can make a big difference in the overall performance of the laptop battery.

When we purchase a laptop computer, we invest a decent amount in the hardware and software. One expects this investment to be amortized over a period of several years. It’s safe to assume that most people switch to a new laptops after 3 to 5 years. However, in most instances, the laptop battery has a battery life of only 12 to 15 months.  After this time you will start to notice that the time you can use your laptop on battery power – starts to reduce rapidly to the point when the battery is only able to provide a few minutes of battery power. At this point, there is no need to buy a new laptop or be confined to using the laptop only with its power adaptor in proximity to a power socket! Several consumers are unaware that the best course of action is to invest in a replacement laptop battery that extends the usable life of the laptop computer. Laptop batteriescan be purchased from the original laptop manufacturers or online from other aftermarket laptop battery retailers.

In general, technological progress is growing at an accelerated pace. Many scientists have stated that the technological progress made in the last few decades is greater than the total technological progress made by humans since the beginning of time. Nevertheless, no matter what the new gadget and what the new technology; the battery is not going anywhere! It may change its avatar but it will continue to remain the oxygen for our mobile devices for the foreseeable future!

Acer Aspire V3-571G Ci3(3rd Genration) 2.5GHz


Overview

Aspire V3-571G
It's apparent that Acer wanted to produce a work horse when they made the Aspire V3-571G. It certainly will get the job done with its impressive 3rd generation Intel Core i3 processor and powerful NVIDIA graphics card. However, the relatively high-end spec points of this machine comes at a cost. The overall build quality of the machine is questionable, and the display is rather lackluster. Can the Aspire's strong performance make up for its weak visual aesthetics and display? Read the full review to find out.

Build and Design




Aspire V3-571G
The Black Glossy plastic exterior of the Aspire 571G initially caught my eye when I took the machine out the box. At first glance it looks sleek, beautifully reflecting light off its surface. However, the second my finger touched the chassis I realized this was a terrible a design choice. The glossy plastic is a fingerprint magnet, as even the lightest touch will sure to result in an unseemly smudge. With only minimal transportation -- usually consisting of taking the notebook to and from work -- the once pristine exterior looked as though someone had viciously whipped their greasy paws all over the device. It's unfortunate that the plastic cover is so easily decremented, as it looked great out of the box; but keeping the machine in that out-of-the box condition appears to be rather unlikely. I fear for the sanity of any OCD consumers (like myself) who may purchase this notebook.

On a brighter note the thin metal coating that supports the keyboard and speakers actually complements the glossy plastic quite well. Furthermore it is fully resistant to fingerprints, it's a shame that the rest of the chassis could not be made of the same material.

Due to how messy the device is sure to become in transport I wouldn't necessarily recommend it, but weighing in at only 5.7 pounds (6.7 with adapter), it is more than manageable to use this device on the go. Additionally the device should fit in most travel bags with its dimensions of 15 x 10 x 1 inches.

Aspire V3-571G
While the fingerprints are problematic, what really worries me about this device is its structure quality. When bending the chassis I was startled to find the device giving way without much effort on my part. Pressure on the back of the display case employs noticeable rippling on the display. I was actually worried about stressing the display panel too much for fear that it might actually break. Obviously Acer had to save costs somewhere offering its impressive graphics card and processor, but the poor build quality makes me apprehensive about the durability of this machine. Seeing how easily the device gives to even the slightest exertion of force, I seriously question how well this device will hold up in the long-run, especially if it is being transported on a consistent basis.

Input and Output Ports

Aspire V3-571G
The V3-571G offers the majority of its ports on the left side of the chassis, including a USB 3.0, HDMI, VGA, Ethernet, and audio and mic jacks. There are also two USB 2.0 ports on the right side along with the disk tray (which sadly, only feeds into a DVD drive). There are no ports located on the back of the device and only the media card reader is situated in the front, located at the front left corner of the device.




Keyboard and Touchpad

Aspire V3-571G
The notebook offers a full size 'Chiclet' style keyboard complete with a dedicated numeric keypad. Thought this keyboard supports all of the bells and whistles, it is a chore to use. The shallow key compression and lack of tactile feedback makes it difficult for users to tell when they have fully struck the desired keystroke. Furthermore, there were several instances where the keypad failed to read my keystrokes at all. Additionally the exceptionally wide keyboard, which almost uses the entire width of the notebook's 15-inch frame, can make entering functions such as ctrl + alt +delete far more difficult than on other keyboards. Also the strangely spaced keys makes it difficult to navigate to some of the more estranged keys, such as the insert key which is not only oddly placed, but difficult to hit due to its reduced size. While this is fine for average use, if you plan on doing something more extensive such as gaming you will certainly want to use an external keyboard.

The touchpad, (which uses Elan drivers in place of Synaptics) is probably the weakest point of the entire machine. The touchpad by design appears sound, offering a scroll section located to right and dedicated right and left click buttons at the bottom of the pad. However, the touchpad is anything but responsive as it constantly lags or even worse fails to read input all together. Furthermore, thought the machine has a quarantined scroll section, I found myself unintentionally scrolling both horizontally and vertically on pages while simply attempting to move the cursor. It's true that most touchpads occasionally misread input such as this, but the pad on the V3-571 Gwas far too inconsistent to be overlooked. The pad will work for simple pointing and clicking; but if you want to do anything else, such as enlarging images or highlighting text, I'd highly recommend using a USB mouse instead.

Screen and Speakers

Similar to the keyboard and touchpad the Aspire's display is somewhat of a disappointment. The 15.6-inch HD LED LCD display only offers a1366 x 768 resolution, which is more commonly seen on smaller 13-inch and 14-inch displays. The large display and low resolution combines in a visual experience that is grainy with minimal color contrast. Additionally the glossy display also offers limited viewing angles. While not terrible from most horizontal angles, tilting the screen slightly forwards or backwards will quickly make the screen appeared dimmed.
Aspire V3-571G





Light is also proves to be a problem, as the glossy finish is highly reflective. While this of course problematic for outdoor use, strong indoor lighting also significantly catches the glossy screen. Again the display is serviceable; but if you are looking for an optimal viewing experience or want to multi-task, you would be better off using an external monitor.

The speakers on the other hand, which use Dolby Digital Home Theater fare much better. Located at the back of keyboard the two stereo speakers are quite boisterous, only requiring around 50 percent capacity to fill most rooms. At 50 percent the speakers perform admirably offering clear, clean audio; though there is a noticeable lack of bass due to the lack of a subwoofer. However, the sound quality does greatly diminish when the audio is pushed past 90 percent becoming noticeably distorted. The speakers offer better than expected audio quality for a budget lap top. It's great for personal use, just don't expect to be able to crank the volume all the way up and receive the same quality.

Dell Latitude Dell E6400/6500Dell E6400/6500 14.1in Business Notebook


Dell's Latitude range is a regular feature of any commute. Get on any morning commuter train and your bound to see Latitudes of all shapes, sizes and ages dealing with spreadsheets, email, documents and the like and probably the most common would be the 14.1in Latitude D630, or its predecessor the D620, both of which received a Recommended Award when we reviewed them. Whereas in the consumer space this form factor is largely being edged out, in the business sector it remains a particularly appealing compromise between performance, portability and usability. No surprise, then, to see Dell using its new 14.1in Latitude E6400 as the poster child of the new Latitude range.

Dell E6400/6500
In the past we've always praised ThinkPad's, like the wonderful X300, for their timeless design and Dell has clearly tried to achieve a similar effect with the new Latitudes. It doesn't quite manage this but unlike the D630, which was more of a refresh than anything else, the E6400 ispart of a complete redesign of the Latitude range and though naturally it retains the professional appearance of previous Latitude's, it brings with it a level of sleekness and style that's previously been missing.
Dell E6400/6500

This is achieved through a combination of some strong angular lines and a classy magnesium alloy construction that's most evident in the brushed metal lid. It's not complicated but it does work and it helps that the E6400 is fairly light and slim for its size. At its thickest it measures 31mm and with the standard six-cell battery it weighs 2.3kg, making for a fairly portable weight that's 100g or so lighter than the D630 it's replacing. Plus, for the adventurous, Dell is even selling coloured lids for Latitude's too, though we can't see many companies being interested in this!

Dell E6400/6500
So far, so good, but the magnesium alloy construction isn't just about making the E6400 look good, it's primarily about strength and here Dell scores another win. Almost every element of the E6400 looks and feels very sturdy and particular praise must be directed toward the hinge. It's very strong and stiff, so bumpy journeys shouldn't be a problem, while the machine is evenly balanced so the front doesn't lift up when opening the lid and/or adjusting the screen angle - something that's a regular annoyance on consumer laptops. There's also a reassuringly secure lid clasp on the front, so you needn't worry about your laptop popping open when inside a bag.

This sense of quality is continued in the keyboard. As ever with Dell, the basic layout of the keyboard is excellent. There's a large and very usable Shift key on the right, below which sits offset cursor keys, while the Insert, Delete, Home, End, Page Up and Page Down keys are all grouped in a grid in the top right. Everything is more or less exactly where you'd expect and want it to be, the only exception being the omission of the 'Menu' key normally found on the bottom row. It's hardly a deal breaker, though, especially if it allows everything else to be just right.



Dell E6400/6500
This layout prowess is coupled with, without doubt, the best feeling Dell keyboard we've ever come across. Keys are tactile, well proportioned, firm and responsive and you have to press extremely hard to garner even a tiny amount of flex. It still lacks the supreme quality found in ThinkPad keyboards, but other than that it's hard to find any fault whatsoever.

Your laptop battery and your health




When you are using the laptop, you should take care of many things related to the battery in order that the battery as well as the user that is you remains safe from any kind of danger.

First, never keep the batteries adjacent to the fire or any place of too much heat since extreme heat can result in the explosion of the batteries.
 

Secondly, any people should not carry the charging devices within the pocket as well as in their purse along with the metal objects, coins, hairpins and paper clips because short circuit may happen which in turn will cause extreme heat.

Third common risk, which you should avoid, is mixing the old batteries with the new ones or mixing dissimilar kinds of charging devices together because such things may cause leakage which is injurious to your health as well as your belongings.
 

The fourth risk occurs when people try to disassemble the various battery parts of their notebook on their own without calling the expert, in order to rectify any kind of problems in the batteries. By no means, you should do this if you don’t have the particular knowledge, because this may cause heavy explosion, which will harm not only you but also your property and other people in the house. There were such incidents in the past where the users have died due to the explosion when trying to disassemble the battery parts.
 

In addition to these, if the users overcharge the batteries or there is anelectrical error, say a short circuit, the chemical elements present within the cells of the battery may turn into an explosive and can catch fire at any moment.
