Surface Book 2 can’t stay charged during gaming sessions

Posted on by
The Surface Book 2 is aimed at graphic pros, but with a stout NVIDIA 1060 GPU, it's a tempting gaming machine, too. As we observed during our review, gaming drains the battery pretty fast, though. Worse, The Verge noticed that the power supply can't...

Intel Haswell’s idle states reportedly won’t play well with some power supplies

Intel Haswell's lowpower state reportedly won't play well with cheap power supplies

One of the staples of Intel's upcoming Haswell processor architecture is its support for lower-power idle states that can rival tablet chips in power consumption, even on the desktop. However, that may come with a big caveat for budget and custom-built PCs: certain power supplies might not cut it. VR-Zone claims that those idle states require as little as 0.05 amps of current, which could be too nuanced for older or cut-rate supplies that deliver power in bigger clumps. That might not be a problem for companies building complete PCs, but Corsair's Robert Pearce tells The Tech Report that it may lead to a lot of motherboard builders playing it safe by disabling those specific modes by default. Many of us, in turn, would either have to buy a fresh supply or toggle the power-saving options ourselves. We've reached out to Intel to verify the truth, but it may be wisest to make a cleaner break from the past with any near-term upgrades.

Rohm 5Wh hydrogen fuel cells power up smartphones, ready for the trash after one charge

Rohm 5Wh hydrogen fuel cells power up smartphones, ready for the trash after one charge

Rohm's hydrogen fuel cells are meant to power smartphones and other mobile devices, but unlike other juicing-up solutions, the cells are only good for one charge. Rohm says disposable fuel cells can be made smaller and lighter than their multi-use counterparts, and as the only byproduct is hydrogen, the company is touting the cells' eco-friendliness. The system generates electricity by using hydrogen that's created by the reaction of a metal material and water. While the device we saw here at CEATEC is a prototype, Rohm may offer its recharging system as both a smartphone case and a USB-attachable juicepack. Each offers 5Wh and can fully charge a handset once. There's also a 200W power generator, which certainly stretches the meaning of portable but can keep a laptop, LCD TV and a peripheral or two going for three to four hours. Rohm says its fuel cells will see a commercial release some time in 2013; for now you can get a sneak peek in our hands-on gallery below.

New fuel cell keeps on going even once the fuel’s dried up

New fuel cell keeps on going even once the fuel''s dried up

Vanadium oxide seems to be the go-to guy in power storage right now. A new solid-oxide fuel cell -- developed at Harvard's School of Engineering and Applied Sciences -- that can also store energy like a battery, also uses the stuff. In the new cell, by adding a VOx layer it allows the SOFC to both generate and store power. Example applications would be situations where a lightweight power source is required, with the potential to provide reserve juice should the main fuel source run out. The team who developed the cell usually work with platinum-based SOFCs, but they can't store a charge for much more than 15 seconds. By adding the VOx, this proof of concept extended that by 14 times, with the potential for more lifespan with further development. Especially handy if you're always running out of sugar.

AMD announces 900MHz version of the Radeon HD 7750, calls it ‘the other 7750’

AMD announces 900MHz version of the Radeon HD 7750, calls it 'the other 7750'

The original Radeon HD 7750 won plaudits for its low-wattage performance and $109 price tag, but now AMD's decided to put out an additional version with 100MHz more clock whizz. The new card also happens to be called the Radeon HD 7750, and it'll sit alongside its doppelganger on the shelves of the world's computer stores just daring you spot the difference. How will you do that? By checking if it requires a separate power supply: the original 7750 was powered entirely through the PCIe slot, limiting its power to 75W and hence its clock speed to 800MHz, while the new one accepts additional power to deliver slightly more grunt and stay ahead of looming competition from NVIDIA. XFX has already jumped aboard with the 7750 Black Edition Double Dissipation priced at $115 after a rebate, and AnandTech says other vendors will follow suit. So, unless you're totally out of power jacks, you know what to look for.

GAEMS announces new Sentry Xbox 360 suitcase, teases Project Vanguard

GAEMS announces new Sentry Xbox 360 suitcase, teases Project Vanguard

How could we forget the GAEMS personal gaming environment? Looking something like a cross between a laptop from the eighties, and a bomb disposal unit, the all-in-one Xbox system was always going to make an impression. Well, with E3 just around the corner, it looks like there might be another model on the way. All we know at the moment is that it's called "Sentry," and will have more of a personal entertainment leaning. This being based on the fact that on top of the Xbox gaming, GAMES only went as far to tease that services like Netflix, HULU and YouTube will be increasingly central to it. The firm is also revealing a new device with the working title "Project Vanguard," about which it's even more secretive. Either way, better make more room on that luggage rack.
