2/7/2016 - ASUS N53J Battery

If you feel like your laptop might as well be a PC because of how entirely codependent it is with its power cord, don’t worry, we get it. The struggle is real.But as we wait for wireless charging to actually become a thing (please be a thing), we have to make do with what we have, and it looks like shutting Chrome down and firing up something more economical is the first thing you should be doing at times of need.As you can see in the demonstration from Microsoft below, when identical laptops were left to run four different browsers - Mozilla Firefox, Chrome, Opera, and Microsoft Edge - in a lab-controlled environment, Chrome absolutely hammers that battery.

In this experiment, which had the four laptops run typical browsing behaviour on a number of popular websites until the battery ran dry, the Chrome computer lasted just 4 hours and 19 minutes, the Firefox computer lasted 5 hours and 9 minutes, and the Opera battery-saving mode computer tapped out at 6 hours and 18 minutes. The Microsoft Edge computer let its hypothetical user last an impressive 7 hours and 22 minutes before they had to curse at the screen, throw the cat off their lap, and haul their first-world-problems butt up the stairs to find the cord.

Comparing Edge to Chrome, that’s a 70 percent increase in time spent unplugged, and at more than 7 hours of battery life, that's entire average work day. So bravo, Microsoft, that’s actually pretty cool.To explain the differences, Microsoft also looked at the power consumption of the four computers' Wi-Fi, CPU, and GPU during the experiments, as each browser cycled through common sites including Facebook, YouTube, Wikipedia, and Amazon. Typical browser behaviour involved opening websites, scrolling through articles, watching HD videos, and opening new tabs for each task.

As you can see in the graph below, the collective telemetry - an automatic measurement of wireless data transmission - from millions of users found that Edge uses up 465 mW, while Chrome needs more than 719 mW. They recorded 493 mW for Firefox."[W]e measure aggregated telemetry from millions of Windows 10 devices around the world. The billions of data points from these devices are consistent with the lab results, demonstrating that Microsoft Edge is more efficient in real-world, day-to-day use than the competition," Microsoft writes on its blog.

Of course, this is all just one giant ad from Microsoft to get you using Edge instead of Chrome, Firefox, or Opera, and what they’re not telling you is that Chrome can do a lot of things that Edge can’t, such as allowing for browser extensions.Microsoft says it’s working on improving Edge’s efficiency and versatility in time for the Windows 10 Anniversary update, and Peter Bright explains the details over at Ars Technica:"Flash content that is not deemed to be central to a page's content will become click-to-play, which is something that other browsers also do. Background tabs will also use fewer resources by making their JavaScript timers fire less frequently and by using coalescing to ensure that they all fire together and hence reduce the number of times that the processor must be woken up.

This shouldn't interfere with listening to music or, say, checking for mail in a background tab, but it should reduce the overhead due to spurious animations and so on."But hey, don’t let Microsoft tell you what to do. If you like Chrome, keep using Chrome... until you're on your last 10 percent and really don't want to get up and find the power cord. And that 70 percent extra battery life could definitely come in handy on long flights.There's no way of knowing at this stage if the improved Edge will keep up its power savings, but as Bright points out, it might actually be a really good option for mobile right now.If you switch over to Edge when you need the extra juice, and follow some of these tips, maybe you won't feel like such a cord slave anymore.HP has issued a voluntary recall for the lithium-ion batteries in over a dozen laptop models due to threats of fire and burns.According to the Consumer Product Safety Commission, the computer manufacturer has received seven reports of HP battery packs overheating or melting. Four of those reports involved property damage.

All told, the recall affects nearly 41,000 devices produced by HP and sold between March 2013 and August 2015. The list includes models from the HP ProBook, HP ENVY, HP Pavilion Notebook and Compaq Presario lines, as well as batteries sold as accessories and provided as replacements. (We have one 15.6-inch HP Pavilion model among the laptops recommended in our Ratings.)The batteries—priced in the $50 to $90 range—contain cells manufactured by Panasonic, which was recently linked to a recall involving batteries in Sony's Vaio-branded laptops.

HP advises customers to stop using the batteries in the specified laptops immediately and to power the devices with a plug instead. To see if your laptop is affected, you can refer to the identification tools outlined on this page. The site also includes information on how to request a replacement battery free of charge.
Only 1% of the HP notebooks sold during the two-year period are affected by the voluntary recall, according to the company.

We need to spend significant time with these backpack setups to truly get a sense of whether they’re going to be a boon to living room VR or a clunky fad, but until then: Bring on the VR ideas great and small.In conclusion, Kaspersky researcher Alexey Komarov said it was “strange to see that nearly two years after the publication of a proof-of-concept demonstrating how a smartphone can be infected though the USB, the concept still works.” He added that “you don't even have to be highly-skilled in order to perform such attacks, all the information you ned can easily be found on the internet.”The lounges are Club One class lounge at Jaipur International Airport, Zesto Lounge SHA at Varanasi Lal Bahadur Shastri International Airport and Prive Lounge at Guwahati Lokpriya Gopinath Bordoloi International Airport.

Amit Srivastava, VP of business development at SpiceJet said: “Air travel is no more a luxury today and with more flyers availing it even more frequently for business and other purposes, an exquisite ambience with added amenities has become a brand necessity.”The new lounges offer seating facilities, complimentary Wi-Fi access, flight information screen, televisions, newspapers and magazines. The additional facilities include drinks, hot shower and mobile or laptop battery recharging. At domestic departures, customers can also avail a fixed menu service during the operational hours of the lounge.

Power plans optimize the computer's settings to let Windows know when to turn off the display, put the PC to sleep, or adjust the screen's brightness to save your laptop's battery life when it's running low, among other actions.
The OS has three built-in power schemes to help create a balance between performance and energy usage (Balanced, set by default and suitable for general cases), maximize performance when playing games or watching movies (High Performance), as well as save energy by cutting off or reducing high-demanding features (Power saver). You may have additional power plans available, depending on your computer's manufacturer. Each power plan has two sets of distinct options to apply when the laptop is plugged in a power source or running on battery.

In this guide, we're showing you how to take control and set your computer to auto-select the power plans (depending on various events) using three apps: Power Scheme Switcher, Power Plan Assistant, and Power Plan Manager. Once installed, all apps get integrated into the Windows autostart sequence, so they will run every time you boot your PC.

Power Scheme Switcher
Power Scheme Switcher takes a straightforward approach to automatically selecting the right power plan, based on the battery life. It provides a shortcut to the Windows built-in features that give you the possibility of customizing options.Once fired up, the tool creates an icon in the systray. Right-click it to open a menu and manually switch to Balanced, High Performance or Power Saver power plans by just clicking their entries.The auto-switching mode is disabled by default. To turn it on, double-click the tray icon, tick the Enable Automatic Switching box, and click the drop-down menus to tell the application which power plan you want to switch to when the computer is Plugged in, On battery or When battery % is less than (set the percent level to monitor). Click Ok when you're done.

Power Plan Assistant
In addition to monitoring the battery life to auto-switch power plans, Power Plan Assistant is capable of launching specific applications after picking a specific power scheme.After installation, it creates an icon in the systray that shows the current battery life. Its color indicates the currently active power plan: green for High Performance, yellow for Balanced, and red for Power Saver. To quickly switch to one of these three profiles, click the tray icon and select the desired option from the menu.

Go to Power Plan Assistant Options -> Advanced Settings Menu -> Automatically switch to Power Saver if battery is less than and select the battery level that will be taken into account for auto-selecting Power Saver on drop.Also, you can instruct the program to switch to High Performance or Balanced profile when the laptop is plugged in (Power Plan Assistant Options -> Advanced Settings Menu -> On plugging in, automatically switch to) as well as to Balanced or Power Saver when the device is unplugged (Power Plan Assistant Options -> Advanced Settings Menu -> On unplugging, automatically switch to).

To auto-open an application when the notebook switches to High Performance, Balanced or Power Saver, go to Power Plan Assistant Options -> Advanced Settings Menu -> Run user-defined application/batch file if power plan changes to, pick the target power plan, and click Define application.In the popup window, click the ... button next to Path to application or batch file empty box and browse for the program to launch (or paste its full path), optionally enter Command-line arguments, then click Save and Close.Make sure to click Save the settings when you're done.

Power Plan Manager
Unlike the previous two apps, Power Plan Manager automatically switches power plans based on which programs are running on your computer; it doesn't depend on the battery life. For example, it can select Balanced to save battery life when you're firing up your media player to watch a movie, since media players are known to be resource-demanding. This works by associating programs to four distinct profiles, which are based on a ranking system (more on that later).

After installing Power Plan Manager, it's necessary to Set up the Power Plan Associations (at least two). The tool has four profiles, which are colored differently and named Best Performance (red), Better Performance (orange), Good Performance (blue), and Default (mandatory, green).Click the menu next to each profile to associate it with one of your computer's power plans (High Performance, Balanced, Power Saver). Before clicking Ok, select the frequency for checking the list of currently running apps (more on that later) from Fast (10 sec), Medium (1 min) and Slow (5 min) in Active Applications Check Speed on the right.

Next, you can set up the list of programs to be monitored by Power Plan Manager. As soon as it detects any of them at the specified time interval, it will automatically switch to whichever power plan you indicated.To do this, click the Add button in the main window, select an app from the list (only the currently running processes are shown), click Ok, then Select a Power Plan to switch to, and click Ok. Only one app can be added at a time, and its color in the Level column indicates the assigned power plan (red, orange, blue, green).How the ranking system works: if you assign a program to the red level, Power Plan Manager will auto-switch to that program's power plan when it spots it running. The orange profile will be enabled only if no programs assigned to the red level are running, the blue one only if no apps from the red or orange profile are running, and the green one only if no apps from all the other profiles are running.

Advanced users can set up scripts to remotely control Power Plan Manager using a simple file or app. For example, you can set up the tool to auto-switch power plans after detecting a scheduled backup task that isn't displayed in the list of active processes (more info about this is available in the help documentation).Play our video guide below to see how these three apps work. You can also download Power Scheme Switcher, Power Plan Assistant, and Power Plan Manager from Softpedia.

Your smartphone isn't the only thing that companies are obsessed with making thinner. Focus has turned to laptops as well, with the belief that making thin-as-paper and light-as-air notebooks will draw in more of the forever-on-the-go working professionals. Thinness also lends itself to design challenges that both excite and loom over OEMs—on one hand, thin laptops should be inherently sexy, but on the other hand, it can be a challenge to make a truly powerful, performance-driven pancake notebook. Enter HP's new Spectre 13 laptop. The company bills it as the thinnest notebook in the world, and its sleek, metallic-accented design complements that title. However, unlike Apple's newest MacBook, HP managed to fit full Core i5 and i7 processors into the Spectre, in addition to three USB Type-C ports and a 4-cell battery. While it doesn't come cheap with a starting price of £1,149, it does do its best to offer more power and a fresh design in comparison to the likes of the MacBook and Dell's XPS 13.
