An anonymous reader writes "According to CNET.co.uk, certain new Dell laptops with a brushed-aluminum finish are giving users more than they bargained for. 'We know this because several CNET staff were hit with an electrical charge while using Dell's new XPS M1530 — and we're not the only ones. Dell's forums are littered with user complaints about the shocking experiences they've had with some systems. The problem only seems to occur in Dell laptops that have a brushed-aluminum finish. These include the XPS M1330 and XPS M1530. It's caused by the two-pronged connection between the mains lead and the power adapter, which isn't earthed properly because of its lack of a third pin. The laptop therefore exhibits an electrical potential (voltage) between its exposed metal parts (the brushed aluminum wrist pad) and earth ground. Since there is no earth, the human body basically acts as a wire that can conduct electric current, hence the tingling, jolting sensation.'"

UNIMurph sends word out of Stanford University that researchers have discovered a way to increase battery life tenfold by using silicon nanowires. Quoting News.com: 'It's not a small improvement,' [lead researcher Yi] Cui said. 'It's a revolutionary development.' Citing a research paper they wrote, published in Nature Nanotechnology, Cui said the increased battery capacity was made possible though a new type of anode that utilizes silicon nanowires. Traditional lithium ion batteries use graphite as the anode. This limits the amount of lithium — which holds the charge — that can be held in the anode, and it therefore limits battery life... 'We are working on scaling up and evaluating the cost of our technology,' Cui said. 'There are no roadblocks for either of these.'"

angryfirelord notes a DesktopLinux article on Lenovo's promise to deliver ThinkPads with pre-installed Novell SuSE Linux Enterprise Desktop 10 in the week of January 14. Quoting: "Lenovo will release pre-installed SLED 10 on its Intel Centrino processor-powered ThinkPad T61 and R61 14-inch-wide notebooks. In February, Lenovo's pre-integrated Novell Linux offering will expand to include some Penryn-based ThinkPads. The starting price for this system will be $949, $20 less than the same laptop with Vista Home Premium."

An anonymous reader writes to mention Nature is reporting that scientists have discovered a much more efficient way to use silicon to convert heat into electricity. This offers the possibility of many different applications including possibly charging your portable electronics just by wearing them close to your skin. "The concept of converting waste heat into electricity isn't exactly new, but it never really materialized due to efficiency hurdles. Now, scientists from the U.S. Department of Energy's (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley think they may have found a key [to] increase the conversion efficiency by a factor of 100."

An anonymous reader sends us to CNET UK's Crave blog, where they report on a demo from CES. So far the only uses for Cell chips have been research stuff and the PS3. Now Toshiba has put a Cell chip into a consumer laptop; they are calling it the Spurs Engine. "The system was demonstrated in modified Qosmio G45 laptops, each of which uses a standard Intel Core 2 Duo CPU in addition to a Cell chip with four 1.5GHz synergistic processing elements (SPEs). Toshiba had four demos running... Demo 3... scans all your movie files, recognizes faces, and creates thumbnails of those faces. You can then click the thumbnails to watch scenes with those faces in, or compile them in a separate playlist."

theodp writes "Mary Lou Jepsen, who left her One Laptop Per Child CTO gig on Dec. 31st, has reemerged with her sights set on a $75 laptop that will be designed by her new company, Pixel Qi, which is described as a 'spin-out' from OLPC. In a Groklaw interview, Jepsen calls for 'a $50-75 laptop in the next 2-3 years' and says it's time to go Crazy-Eddie on touchscreen prices as well." This is probably good news to Bruce Perens, who thinks that the recent report of Microsoft's dual-boot XO project (with Windows as well as the Linux-based Sugar OS) is a feint driven by Microsoft's fear of "the entire third world learning Linux as children." Update: 01/10 21:22 GMT by T : ChelleChelle adds a link to an excellent interview with Jepsen in the ACM Queue, in which she discusses OLPC and some of the technologies it contains.

Ian Lamont writes "The OLPC Project and Microsoft are developing a dual-boot system to put both Linux and Windows on the laptops, according to an interview with Nicholas Negroponte. The article is thin on details, as the OLPC/Microsoft talks are apparently at an early stage. Could this be the end of the OS wars in Nigeria and other developing countries?" While Microsoft has been working on an OLPC-capable version of Windows for some time now, the interesting thing here is the dual-booting provision, rather than forcing users into an either-or choice.

Yogi_Stewart_4 writes "More OLPC/Intel love — apparently Intel used 'underhanded' tactics to try to block sales' contracts of the OLPC, trying to reach the customer directly after an agreement had been reached. "They would go in even after we had signed contracts and try to persuade government officials to scrap their contract and sign a contract with them instead. That's not a partnership." Mr Negroponte cited an example in Peru where Intel sales staff tried to persuade the country's vice-minister of education, Oscar Becerra Tresierra, to buy the Intel Classmate PC."

nerdyH writes "A new Linux-based portable media player (PMP) features an eyeglass-like head-mounted display with 800 x 600 resolution. Dreamax's Indicube i-800 PMP provides an experience similar to sitting two meters away from a 54-inch screen, the vendor claims. It uses an 0.44-inch eMagin OLED display, claimed to offer the smallest pixel pitch in the industry."

An anonymous reader writes "Marking the start of news releases from this year's Consumer Electronics Show, Lenovo has dropped a major announcement on consumers - the arrival of a new line of notebooks. The IdeaPads will be the consumer-friendly companion to the ThinkPads. The announcement covers three notebooks, the 17" Y710, the 15" Y510, and the 11", 2.4lb U110. The IdeaPads will bring a number of firsts to Lenovo's notebooks, including a SSD upgrade option, dual hard drives (Y710 only), and a 17" notebook."

SkinnyGuy writes "Mixed into all of PCMag's CES preview coverage is an interesting story about a projector that's no bigger than an iPod. An early version showed up at last year's CES, but some of the guts weren't inside the small body. Now they are. It uses lasers to project the image. Really fascinating, futuristic stuff."

An anonymous reader writes "This OLPC (One-Laptop-Per-Child) tutorial teaches you how to develop Python activities for the XO laptop. It covers the ins and outs of Sugar (the XO user interface, or UI) and the details behind activity development. You will also learn about Python programming, Sugar application program interfaces (APIs) for Python, and platform emulation with QEMU. Learn OLPC application development and help the worlds children."

theodp writes "The One Laptop Per Child project suffered a blow Monday, with CTO Mary Lou Jepsen quitting the nonprofit to start a for-profit company to commercialize technology she invented with OLPC (the first of Jepsen's pending OLPC patents was published by the USPTO on Dec. 13). The OLPC project halted consumer sales of the cheap laptop at the end of December."

yali writes "The U.S. Transportation and Security Administration has issued new rules limiting travel with lithium batteries. As of January 1, no spare lithium batteries are allowed in checked luggage. Batteries carried in the cabin are subject to limitations on per-battery and total lithium content, and spare batteries must have the terminals covered. If you're returning home from the holidays with new toys, be sure to check out the new restrictions before you pack."

Lucas123 writes "Panasonic plans to unveil the thinnest Blu-ray Disc drive made yet at the upcoming CES show. The drive is 9.5mm high, which allows it to fit into standard laptop form factors instead of requiring manufacturers to redesign systems to fit high-def DVD players as they've been doing. 'Panasonic has already begun offering samples of the drives to laptop makers with the hope that the companies will build it into new PCs.'"

akintayo writes "Digitimes reports that first-tier notebook manufacturers are increasing the standard installed memory from the current 1 GB to 4GB. They claim the move is an attempt to shore up the costs of DRAM chips, which are currently depressed because of a glut in market. The glut is supposedly due to increased manufacturing capacity and the slow adoption of Microsoft's Vista operating system. The proposed move is especially interesting, given that 32-bit Vista and XP cannot access 4 GB of memory. They have a practical 3.1 — 3.3 GB limit. With Vista SP1 it seems that Microsoft has decided to fix the problem by reporting the installed memory rather than the available memory."

brianmed writes to tell us that Stanford researchers have created a new use for silicon nanowires that promise to reinvent lithium-ion batteries. "The new version, developed through research led by Yi Cui, assistant professor of materials science and engineering, produces 10 times the amount of electricity of existing lithium-ion, known as Li-ion, batteries. A laptop that now runs on battery for two hours could operate for 20 hours, a boon to ocean-hopping business travelers. [...] The lithium is stored in a forest of tiny silicon nanowires, each with a diameter one-thousandth the thickness of a sheet of paper. The nanowires inflate four times their normal size as they soak up lithium. But, unlike other silicon shapes, they do not fracture."

theodp writes "PC Magazine's John C. Dvorak has a unique take on the cute One Laptop per Child XO-1, deeming the OLPC project a naive fiasco waiting to unfold that sends an insulting 'let them eat cake' message to the world's poor. When it comes down to a choice of providing African kids living in absolute poverty with access to Slashdot or a $200 truckload of rice, Dvorak votes for the latter. Buy ten OLPCs if it assuages your guilt, says Dvorak, but 'I'll donate my money to hunger relief.'"

Stony Stevenson passed us a link to an IT News story about Microsoft's recent request that the folks behind the XO laptop redesign it to suit their needs. The company now wants to be able to run Windows XP on the highly-publicized and inexpensive portable. "Microsoft general manager ... Utzschneider says a shrunken version of Windows XP could potentially run on 2 Gbytes of flash memory. The XO, however, can only hold 1 Gbyte. As a result, Microsoft wants the XO's designers to add a slot through which more memory can be added via a secure digital (SD) card, Utzschneider said. Microsoft's renewed interest in participating in OLPC might be viewed by skeptics as an admission that a rival offering for developing markets called Classmate — which uses an Intel processor on Microsoft software — has failed to catch on."

Psychor writes "Dell has released a high specification new laptop complete with World of Warcraft branding (Horde and Alliance versions available). With a starting price of $4,499 it's not cheap, but does feature SLI graphics and AGEIA PhysX technology (a laptop first). RAID and solid state storage are also options." Unfortunately for purchasers, the laptop won't boot on tuesday mornings until early afternoon, and some days you just won't be able to log in.
