Memory capacity has improved dramatically, and there is now support for up to 2TB of DDR4 RAM – or at least there will be once 128GB DDR4 DIMMs become readily available.Expandability has been given a boost, too, and in addition to Thunderbolt 2 and HP Z Turbo Drive expansion via dedicated PCI Express cards, there are three Gen3 PCIe x16 slots and room for up to eight 2.5in drives in dedicated internal bays. It’s also 5U rack mountable.Further down the range, the Z640 shrinks slightly. It comes in a 4U rack-mountable chassis – but retains support for dual CPUs with TDPs of up to 145W, and its eight DIMM slots accept up to 256GB of RAM.Meanwhile, the entry-level Z440 workstation has been redesigned, and provides support for a single 140W TDP CPU and up to 128GB of RAM. HP has also upgraded its 15in and 17in mobile workstations; these have emerged as the ZBook 15 G2 and ZBook 17 G2. Click here to read our HP ZBook 17 review.

Outwardly, nothing has changed, with both sporting the same burly, metal-framed industrial design to last year’s models. Look closer, however, and just like their desktop cousins, the single Thunderbolt ports now reach Thunderbolt 2 speeds.The hardware roster has changed slightly, too, with Intel’s Haswell Refresh range of CPUs taking centre stage alongside a range of professional GPUs from AMD and Nvidia. Both models also now support up to 32GB of RAM.Both laptops also possess M.2 slots which are ready for HP’s Z Turbo Drive, or indeed any aftermarket M.2 SSD. It’s worth noting that the previous generation of the ZBook 15 and ZBook 17 also had M.2 support, but these were connected via a slower SATA interface. In our time with the new models, we saw the Sandisk drives managing sequential read speeds in the region of 700MB/sec – around 250MB/sec faster than the SATA M.2 generation.HP also offers a variety of display upgrades over and above the standard Full HD displays, with 3,200 x 1,800 QHD+ and wide-gamut Full HD DreamColor panels set to bump up the price significantly.

HP has announced the USB-powered U160 portable monitor at CES 2013, potentially answering the prayers of sales reps who struggle to crowd people around an ultraportable laptop for presentations.The U160 is a 15.6in display with a slightly old school resolution of 1,366 x 768, but its biggest benefits is how it works – getting both its power and graphical feed from a laptop’s USB ports drastically reduces the amount of cable needed to power a presentation.The iPad Smart Cover-style case keeps it safe in transit, although its 1.5kg heft means it weighs almost as much as the average ultraportable on its own.The price could prove appealing, though: the U160’s price in the USA will be $179, or roughly £110. It will go on sale later this month.

Chip manufacturer Marvell is showing off the One Laptop Per Child XO-4 Touch at CES 2013, as the charity project makes another bid to crack the low-cost laptop.The hybrid laptop, announced last year and launching in the first quarter of this year, is designed for educational use in emerging economies.Price and a release date are expected to be announced later this year, but attendees of CES press preview event CES Unveiled were able to get their hands on the device early at Marvell’s booth.The XO-4 Touch is a convertible laptop with a dual-input, 7.5in touchscreen that can run in either standard backlit mode or in a low-power greyscale mode designed to be legible outdoors. Touchscreen capabilities come courtesy of infrared technology and the machine weighs either 1.36kg with a lithium iron phosphate battery, or 1.58kg with a standard NiMH cell.There’s either 1Gb or 2GB of DDR3 RAM available, plus up to 8GB of storage. Computing power comes from Marvell’s 1.2GHz PXA2128 system-on-a-chip. The OS is a version of Fedora 18.The OLPC XO-4 Touch has plenty to prove: the project’s champion, Nicholas Negroponte, predicted sales of five million OLPCs by 2007; the reality in 2009 was closer to 1.5 million, leading some to wonder about the long-term viability of cheap laptops for emerging economies.

Lenovo has unveiled new Ultrabooks, mainstream laptops and all-in-one PCs at CES 2013, all of which take advantage of touchscreen technology.”We’ve aggressively integrated touch across our consumer PCs so that we have one of the largest portfolios of Windows 8 touch products available,” said Peter Hortensius, senior vice president at Lenovo.At the top of the range are Lenovo’s IdeaPad U310 and U410 Ultrabooks, which add ten-finger multitouch support to previous versions. Both Ultrabooks offer tablet-like response times, with Lenovo promising wake-up times of less than one second.Lenovo has also introduced touch to its mainstream IdeaPad laptop range, with the IdeaPad Z400 and IdeaPad Z500 also boasting ten-finger support.Two all-in-one PCs now include touch as well. The IdeaCentre A730 will be available with a 27in 1,920 x 1,080 display with ten-point multitouch, while the more affordable 23in IdeaPad C540 comes with an optional touchscreen.

Lenovo’s final touchscreen offering is a new monitor, the ThinkVision LT1423p Mobile Monitor Touch. Again, this includes full ten-finger touch support.Its 13.3in display includes a 1,600 x 900 resolution and promises great viewing angles thanks to an AH-IPS panel protected by Gorilla Glass.The Ultrabooks and laptops will go on sale from March, while the IdeaCentre A730 becomes available in June. UK prices weren’t immediately available.People who get undressed in front of their mobile devices or computers without a second thought could be the unwitting victims of prying eyes, it’s been claimed.According to research by Kaspersky Lab, Britons are oblivious to the threat of webcam hacking, where an attacker surreptitiously takes control of a device’s camera and uses it to spy on the owner.The study of 2,000 people showed 57% of adults have sex within sight of a camera, be it on their mobile phone, tablet, laptop or PC, while more than a third admitted to getting undressed in front of these types of devices. A further 29% said they took camera-enabled devices to the toilet or bath with them.

Of the 17.5% of mobile phone and tablet users who do try to take countermeasures, 40% believed simply closing the camera app was enough to disable it – in reality, it’s impossible to disconnect the camera on these devices, Kaspersky said.The possibility of a “peeping Tom” in your webcam isn’t the only concern. The same type of hack can be used to steal photos from the user’s device, the company claimed.Kaspersky’s senior security researcher, David Emm, said: “We think of our mobile devices as our window on the world, not realising that for cybercriminals it could be their window into ours.””Hacking into a device’s camera offers those with malicious intent access to our images, our most intimate moments, our identities, and the people we most want to protect, such as our children,” he added.http://www.dearbattery.co.uk

The research was carried out to mark the UK launch of the company’s 2015 suite of security products – Kaspersky Antivirus 2015, Kaspersky Internet Security 2015 and Kaspersky Internet Security Multi-Device 2015 – which have new features to combat this type of security threat.All three products include a module called Webcam Protection, which defends against webcam hacking by monitoring which applications are trying to connect to the webcam. Users are then warned of these attempts and, if necessary, the module can block webcam access.Another new feature of all three products is System Watcher, which specifically protects against ransomware, such as Cryptolocker.The module analyses the programmes running on the computer or device, and if it detects a suspicious software trying to modify a file, it will immediately create a backup of it on the user’s computer, minus any external changes.

Then, if further analysis shows that the programme attempting to change the file was malicious, any changes that have been made will be undone, the company said.The final key new technology is Wi-Fi Security Notification, a feature present in Internet Security 2015 and Internet Security Multi-Device 2015.It verifies the security of Wi-Fi hotspots, the company said, and notifies the user if potential threats are detected, such as a vulnerable network connection or the transmission of an unencrypted password. It also offers tips and recommendations on how customers can secure their home Wi-Fi network.All three products run on Windows XP to Windows 8.1, Mac OS X 10.6 to 10.9, and Android 2.3 to 4.3. However, Webcam Protection, System Watcher and Wi-Fi Security Notification are only available in the Windows version of the products.

One of the most transformative upgrades you can make to an ageing laptop is to swap the mechanical hard disk for an SSD; however, since the cost per gigabyte is much higher than for mechanical disks, the switch usually means sacrificing capacity.WD aims to solve that problem with its Black[sup]2[/sup] dual drive, which combines a 120GB SSD and a 1TB mechanical hard disk in a single 2.5in shell. The idea is that you can run your OS and applications from the fast SSD, while – as with many desktop PCs – storing your movies, music and photos on the slower but more capacious mechanical disk.The drive is 9.5mm thick, and uses a single SATA/600 data and power connector, so it should fit in most laptops with a user-accessible drive bay. The first time the Black[sup]2[/sup] is hooked up, it appears to Windows as a standard 120GB SSD, ready for you to clone your system or install a fresh copy of Windows onto. With this done – using the free WD-branded copy of Acronis True Image and the USB-to-SATA cable that’s helpfully supplied – you can boot into the system and run WD’s proprietary software to set up the 1TB mechanical hard disk as a second partition.
