12/1/2016 - Lenovo Thinkpad T420S Battery

We hope the 15in versions of the 2016 MacBook Pro maintain these quad-core processors - the reason for our concern is the fact that the Mac mini when updated in October 2014 lost its quad-core processor options.While the 13in models feature 8GB RAM, the 15in models all offer 16GB RAM and it's likely that the 16GB of RAM offered by the 15in models will remain.

The 15in MacBook Pro is Apple's only laptop to offer the dual-graphics card setup that allows users to switch graphics cards depending on the kind of work being performed. So the less power-hungry apps need only use the integrated graphics, thereby draining less of your battery, but power-intensive apps can use the specialised graphics processor. The Mac switches between the two processors according to the application being used. It's the best of both worlds. Hopefully Apple will continue to offer the dual graphics processor option in the high-end MacBook Pro.

The 13in Retina MacBook Pro offers 10 hours of battery life and the 15in model offers 8 hours. Given that the MacBook Air offers 12 hours of battery life in the 13in model, and 9 hours in the 11in version - despite the fact that the thinner MacBook Air has less battery space, the Pro model is looking like it lacks the stamina of its slimmer sibling. However, the MacBook Pro is a more powerful and therefore more power-hungry machine, so it is unlikely to ever match the battery life of the Air.

We'd like to see more battery life offered by the new 2016 models, though, aided by the new Skylake processors, and other energy use enhancements offered by El Capitan.The 13in Retina MacBook Pro 2015 was quickly announced during Apple's 9 March 2015 'Spring Forward' Apple Watch event, alongside updates to the MacBook Air, and an all-new MacBook, which you can read about in our MacBook round-up article here.The changes to the 2015 13in MacBook Pro were all under the hood. The 13-inch MacBook Pro got a new Intel Broadwell processor chip with speeds up to 3.1 GHz and Turbo Boost speeds up to 3.4GHz - and Intel Iris Graphics 6100. And its flash memory is twice as fast, with claimed throughput of up to 1.6GBps.

Apple also claims that battery life is longer: the 13-inch Retina MacBook Pro now delivers up to 10 hours of general use or up to 12 hours of iTunes movie playback, the company says.There was one change to the physical design of 2015's Retina MacBook Pro: it gained the Force Touch trackpad seen on the Retina 12-inch MacBook notebook.

According to Apple's press release, this will make all the difference to your day-to-day computing experience: "The 13-inch MacBook Pro with Retina display features the all-new Force Touch trackpad that brings a new dimension of interactivity to the Mac. The new trackpad features built-in force sensors that allow you to click anywhere and haptic feedback that provides a responsive and uniform feel. You can even customise the feel of the trackpad by changing the amount of pressure needed to register each click. The Force Touch trackpad also enables a new gesture called Force Click, a click followed by a deeper press, for tasks like pulling up the definition of a word, quickly seeing a map or glancing at a preview of a file."

In May 2015 Apple added two new 15-inch variants of the MacBook Pro to its Online Store, complete with Force Touch capabilities.The base model packs a 2.2GHz quad-core Intel Core i7 processor with Turbo Boost up to 3.4GHz, 16GB of RAM and 256GB of flash storage. That’s without mentioning the Intel Iris Pro Graphics and the Retina display. It also boasts Force Touch.For those of you that need a bit more bang for your buck, Apple also stocks another variation. This one boasts a 2.5GHz quad-core Intel Core i7 processor with Turbo Boost up to 3.7GHz, as well as 16GB RAM and a 512GB of flash based storage. The new MacBook Pro also offered faster flash storage, better discrete graphics on the top of the range, and better battery life.

One surprise was that the 2015 15in Retina MacBook Pro models still featured Intel’s Haswell processors, rather than the newer Broadwell, suggesting Apple is skipping the much delayed Broadwell processors and waiting for Skylake. Probably Broadwell wouldn’t have made a great deal of improvement to the 2014 models.Another reason why Apple has skipped Broadwell is the fact that the quad-core Broadwell chips that Apple would have required for the MacBook Pro models (and the new 27in Retina iMac that was also introduced) hadn't launched at the time.

All eyes will are on Intel now, as the company gears up to release Skylake, which is what everyone is really waiting for. Hopefully it won’t take Intel another year to release Quad-core versions of Skylake or we will have a long wait for faster Macs.Size: On average, a laptop weighs 2.7kg, which is a lot for most kids to lug around. Aim for a screen (which determines both size and weight) of between 11 and 13-inches.Build: School can be a rough and tumble place. A laptop needs to be durable. Try opening up the laptop screen by its corner and feel for any flexing. Avoid anything that looks like it could break. If your budget allows, buy a laptop with a metal body.

Before Intel coined the term "ultrabook" to describe thin, light, and yet powerful mobile PCs, the category was generally defined by the spliced adjective of "thin-and-light." That came to mind today as I encountered Samsung's Notebook 9 laptops for the first time. Much like LG's Gram lineup, these new Windows laptops from Samsung are all about shaving off the last millimeter of thickness and last possible milligram of weight. The 13.3-inch variant weighs just 0.84kg / 1.85lbs while the 15-inch Notebook 9 rises to 1.29kg / 2.84lbs. If those numbers aren't doing a good enough job of conveying exactly how light these machines are, just take a piece of thick cardboard, fold it in half and you'll have a pretty realistic home model.

Another way to describe Samsung's Notebook 9 PCs is that they feel as light as if there were no battery inside them, which is fitting, because the battery is the main thing that worries me about them. I enjoyed using LG's Gram laptop when I reviewed it last year, but its thinness came at the cost of good ergonomics, a keyboard backlight, and, most importantly, good battery life. Glancing at Windows 10s battery life estimator on the 15-inch Notebook 9, I was promised 3 hours and 33 minutes off a remaining charge of 83 percent. That doesn't fill me with confidence that Samsung can pull off the wild trick of making insanely svelte machines that also last for an entire day. Maybe with an ARM processor, but not with an Intel x86 chip inside.

Battery: Most classrooms don't have enough power outlets for an entire group of pupils so schools don't let children use a power adaptor. Aim for a battery life of at least six hours but aim for eight if possible.Safety: Because school laptops can get lost or stolen, play it safe and install a free anti-theft app. Prey is free and available for Windows, Chrome OS and Macs. With Prey you can track down and lock a lost or stolen laptop.Ask the school: Check with your child's school to see if they recommend any particular operating systems. Chromebooks are a low cost option for younger pupils. Windows is popular but If your home is Apple equipped, the Macs may be your best option.

Unless Johnny and Joanne are decoding the human genome at school, they won't need a huge CPU. For classroom chores, an Intel Core i3 or Celeron M is all they'll need.If you want to give them more power, an Intel Core i5 delivers a good balance between cost and performance. If you must push the performance boat out, go for a Core i7.RAM (memory): This makes a huge difference to performance. A laptop with 4GB is plenty, unless your children are into video and photo editing or gaming.Hard Drive (storage): This is where everything is stored. A 256GB hard drive should be enough. If performance matters, go for an SSD (solid state drive). They're a lot faster than a conventional hard drive.

If a larger hard drive is outside your budget, consider an external USB hard drive.Also, set your kids up with a Dropbox, OneDrive or Google Drive account so they can store files online.Wi-fi: This is how the laptop will need to connect to the internet. The wireless technology is regularly updated so try and get the current standard which is 802.11ac. This will mean they get the fastest connection possible, especially since most schools have ultrafast broadband.Familiarity with Windows and its productivity software is considered essential by most employers. Tech support is also widely available.

This is a good thing as Windows is the operating system that is most often targeted by malware. The huge variation in PC configurations also means Windows can be prone to crashing.Google's OS is a simple, reliable and an affordable option. It uses Google's online services for much of its functionality.Most Chromebooks are priced around $400-$500. This means that if they're damaged (or stolen) the impact on your wallet is less than that of a PC or Mac.For browsing, email, social media and basic office tasks, a Chromebook is ample. If your child needs to run more complex apps, a Chromebook mightn't be the best choice. Chromebooks also back up data to your Google account. Their downside is that you need an internet connection to use most apps. Some can be accessed without an internet connection, but their functionality can be limited.
