Acer Aspire 4741G-332G50Mn Battery

Workstation laptops have traditionally opted for Intel’s powerful Core i7 processors, due to their power and size. However, a consumer-grade processor is nothing compared to Intel’s professional-grade Xeon chips. So, when Intel quietly announced, via a blog post on Friday, that it would be bringing its Xeon processors to laptops, it makes complete sense for Lenovo to adopt one as quickly as possible.The benefits for mobile workstation users are obvious. Xeon chips have more cores, which allows for more simultaneous applications. They can also support the more reliable ECC memory standard – which automatically corrects common data corruption errors – so workers don’t have to make compromises when working away from the office.

The Lenovo ThinkPads are competitively priced for their power, especially when compared to other workstations on the market. Lenovo states that both devices will be available from “Q4 2015” and pricing starts at €1,599 (around £1,500) for the P50, with the P70 setting you back €2,099 (around £1,900).With IDF just around the corner, it’s likely we can expect to see more announcements of Xeon-powered workstation laptops slip out over the coming weeks.The larger of the two, the ThinkPad P70, is a 17in workstation laptop that can be loaded up to a whopping 64GB of DDR4 ECC memory, taking up to four storage devices and a terabyte of PCIe SSD storage. It’s also equipped a DVD RW drive, USB3, HDMI, Mini DisplayPort, gigabit Ethernet ports and two of Intel’s Thunderbolt 3 ports – Intel’s take on the USB Type-C connection. It also features Nvidia’s professional-grade Quadro GPU X-Rite Pantone colour sensor below the keyboard and comes with an optional 1920 x 1080 pixel touchscreen, although you can opt for a 3840 x 2160 pixel non-touch screen.

Lenovo’s ThinkPad P50 manages to pack almost all of this into a smaller 15.6in frame, but ditches the DVD RW drive and one of the Thunderbolt 3 ports. It’s essentially the P70 but weighs just 2.5kg instead of 3.4kg, making it suitable for mobile workers who don’t want to compromise on power.Car companies like BMW, Hyundai and Toyota have spent the last few years developing hydrogen fuel cell technology, and it’s looking more like a viable alternative to lithium-ion batteries. Hyundai has just released the ix35 FCEV, the UK’s first mass-produced hydrogen-powered car – and we took it for a drive around London.Electric cars are becoming more popular, thanks in part to cheap, affordable vehicles such as the Nissan Leaf, Renault ZOE and the compact but expensive BMW i3.

These vehicles get their power from lithium-ion batteries – similar to the ones that power our smartphones and laptops – but they come with all the same drawbacks. They’re heavy, performance can degrade over time and, worst of all, they need regular charging. But there is an alternative. Hydrogen fuel cells offer a longer range, are quicker to recharge and, best of all, their only waste product is water vapour.The ix35 FCEV is based on the conventionally powered ix35 SUV, but has a completely different powertrain. It’s similar to an electric vehicle – with one major exception. Hydrogen fuel cells release energy in a chemical reaction by combining hydrogen and oxygen to produce electricity, while electric cars simply use a battery’s charge.

Hydrogen fuel cells have larger range than their lithium-ion counterparts and are potentially greener too. The only waste products of the chemical reaction are heat and water. Better yet, refilling a fuel cell can take around three minutes – much better than the recharging time of an EV.Hydrogen is extremely flammable, so must be stored in a reinforced, chilled environment, while the oxygen required for the reaction is collected from the air. This obviously takes some pretty smart engineering, but the potential benefits are big.When driving the Hyundai around London, it’s very easy to forget the sophistication of its power source. Apart from the left-hand drive configuration of the car we used, there’s very little difference between it and a standard SUV. The boot is smaller than you’d expect, as much of it is taken up by the car’s two fuel cells – but almost everything else in the car is completely standard. The ix35 uses 100kW and two hydrogen storage tanks to offer a top speed of 100mph and a range of 369 miles.

Alongside a smooth power delivery, one of the best and worst things about the car is its total lack of noise. Although the silence made driving a quieter experience, it also had a worrying side effect – pedestrians didn’t seem to hear or notice the car. The result? On busy high streets, I had to avoid several people walking in front of the car simply because they didn’t hear it.While the ix35 FCV appears to tick all the boxes – and even has increased range compared to EVs – its main issue is going to be infrastructure. Electric vehicles are often overlooked for their lack of charging stations, and the situation is even worse for hydrogen-powered vehicles. With only 15, yes fifteen, hydrogen charging stations currently in the UK, the ix35 might be commercially available, but it’ll need significantly better infrastructure to be truly viable.

In some ways, the HP Elite x2 is a boring old rehash of established design ideas. A Windows tablet with a detachable keyboard, kickstand and stylus and a 12in display, designed to take on the Microsoft Surface Pro 4 at its own game. There are loads of these on the market right now, some good, some bad.HP is hoping to distinguish its own effort by offering something last seen in the 1990s: the ace up the Elite x2’s sleeve is its repairability. Unscrew the rear panel (via a series of Torx screws beneath the kickstand at the rear), and it’s possible to remove and replace the screen, hard disk and memory, something that’s impossible to do easily or quickly on a consumer device such as the Surface Pro 4.

But before you get too excited about adding RAM and improving hard disk capacity, this isn’t a development aimed at consumers, but businesses who buy such devices in bulk, saving them large bundles of cash. Not having to replace a device or send it back to the manufacturer every time a single component goes pop could save thousands and thousands of pounds over the lifecycle of a product such as this.Let’s take a look at the design for a moment. Just like countless Surface Pro 4 rivals before it, the Elite x2 consists of a tablet part, in which all the core components reside – the CPU, the RAM, storage and battery – and a keyboard cover that attaches to the spine of the tablet magnetically.The tablet is nicely designed. In fact, if you follow the fortunes of Surface Pro 4 rivals avidly (what do you mean you don’t?), you’ll probably notice a few similarities with HP’s consumer-grade HP Spectre x2 tablet.

The chassis is constructed from a robust-feeling matte-finish aluminium that feels silky under the finger. There’s a glossy black strip running along the top edge at the rear that houses the rear camera module and flash, and the whole thing, ignoring the slightly geeky-looking HP logo, is pleasingly attractive. It’s very slightly heavier and thicker than the Surface Pro 4, but it’s close enough to hold its own and, if anything, build quality favours the HP device. The kickstand at the rear has a built-to-last feel to it, supporting the tablet at angles ranging from near-vertical to almost flat, and it feels more sturdy than the Surface Pro 4’s flat blade.Just like the Surface Pro 4, this HP has tough Gorilla Glass on the front: the top-spec 1,920 x 1,280 model I have here gets Gorilla Glass 4, while the cheaper 11.6in, 1,366 x 768 and 1,920 x 1080 options get Gorilla Glass 3.
