Windows 7 Causes Battery Issues

January 29, 2010

It seems as though the upgrade to Windows 7 has been wreaking havoc on some users’ notebook batteries, dropping the running time by as much as 70%.

Word comes via TheRegister of the reasonably widespread complaints, with many users holding the upgrade to Windows 7 responsible for their sudden and noticeable drop in overall battery life. Moreover, the piece points to the forums over at Microsoft’s own TechNet that sees hordes of users with roughly the same complaint – that their battery life has been greatly diminished since the upgrade to Windows 7. Indeed, there’s been so widespread an outcry that Microsoft has responded directly to address the issue.



Acer Gets Greenpeace Seal of Approval

January 15, 2010

Today sees the launch of two new laptop models from Acer that come with the Greenpeace seal of approval. Part of the company’s Timelines series of slimline, light laptops that use Intel’s ULV (ultra low voltage) Core 2 Duo microprocessors for long-lasting batteries – the Acer Aspire 3811TZ and Aspire 3811TZG will please tree huggers everywhere.

Certified under Greenpeace’s ‘Who is Green’ list as being free of two toxic substances – polyvinyl chloride (PVC) and brominated flame retardants (BFR) – with the exception of their power cables, the two laptops are also designed to reduce energy consumption and can be recycled, the company said in a statement.


RCA Shows off Wireless Charger

January 11, 2010

RCA has taken the time at CES this year to show off a wireless charging arrangement it calls the AirEnergy, which is charged entirely by wireless signals, elegantly enough.

Until now, Powermat had been the wireless charger to watch...

While we’ve been hearing about wireless charging, and some of us practically drooling over it, for years now, it seems as though RCA is a shoe-in to the first company to really hit with something usable, affordable and practical. RCA’s AirEnergy is, as we said above, charged entirely by ambient Wi-Fi, which means that it will charge as you go about your day, likely with it buried somewhere near the bottom of a bag or in a pocket somewhere.


Teardown Reveals Nexus One Guts

January 7, 2010

It was only a matter of time, but it seems that Google’s entry to the smartphone market has already been summarily dismantled and the various bits and pieces subjected to some scrutiny.

iFixit, whose name should be familiar to people who follow the news of new releases in mobile hardware closely enough to want to see hardware stripped down, managed to get its hands on Google’s Nexus One, and promptly strip it down to its component parts.


Windows 7 “Godmode” Only the Beginning

January 7, 2010

It seems that word that people are using the Windows 7 “GodMode” settings panel trick has reached right back to Microsoft, with the revelation that there are plenty of other similar shortcuts.

Cnet managed to score an interview with Microsoft’s Windows division president, Steven Sinofsky, who was fairly happy to talk about the recently uncovered GodMode tweak in some detail. According to Sinofsky, the aim with tweaks like GodMode is to provide easy access to a plethora of settings for developers who might conceivably need to test everything in as little time as possible.


Sony Debuts Short Range Wireless

November 30, 2009

Sony is showing off some new short range wireless technology it calls TransferJet, which supports reasonably high-speed, short range wireless data transfer, ideal for portable devices.

According to Engadget, the whole idea with TransferJet seems to be that it offers an alternative to USB-style connections for data transfer to mobile devices. It might seem relatively simple, but with a theoretical maximum speed of 560Mbps at a range of 3cm there’s no real reason to need something like USB for mobile devices once hardware like TransferJet achieves some solid penetration.

Of course, it’s excellent to see that there’s also some fairly widespread support for Sony’s new attempt to make short-range wireless technology widespread. Brands that we’re interested to see supporting TransferJet include Canon, Nikon, Samsung, Casio, Kodak and Olympus. Admittedly, they’re mostly camera manufacturers for now, but the fact that there are some phone companies in there is fairly interesting.

If only for simple things like transferring contact information and photos, it’s certainly an interesting concept, and in tandem with things like induction-based wireless charging for mobile devices it certainly does make for a very interesting bit of near-future wireless charging and fast data-transfer when it comes to mobile devices.

For now we’re left a little wanting when it comes to details of devices we can expect to see it in, but if you’re at all interested to see what Sony expects to see its short range wireless used for then you’d do well to check out the video over at Engadget, where it shows some genuinely impressive and very simple shots of the devices at work.

Kindle 2 Update Adds PDFs and Better Battery

November 25, 2009

Amazon is updating its Kindle and adding some pretty impressive bits and pieces, including extending the device’s battery life of its Kindle 2 by up to 85% making the whole thing a lot more attractive, but that’s not all.

Word comes from TheRegister that Amazon has also added native PDF support, which has long been one of the features other ebook readers have claimed over the Kindle. The question now is whether or not these updates will just push those who have been, until now, just considering picking up an ebook reader to go for Amazon’s offering or if we’ll just see existing Kindle customers exceedingly pleased with the latest additions.


Nokia Initiates Charger Recall

November 9, 2009

Nokia has announced the launch of what it’s calling an “exchange program” for up to 14 million users who are experiencing issues with the company’s chargers.


Engadget is reporting that Nokia has uncovered an issue with the durability of its chargers whereby they seem to come apart and then pose a threat to users who may suffer electric shocks from using the devices. The official word from Nokia is that,

“We have determined that the plastic covers of the affected chargers could come loose and separate, exposing the charger’s internal components and potentially posing an electric shock hazard if certain internal components are touched while the charger is plugged into the socket.”


Sony Issues AC Adaptor Recall

October 30, 2009

Sony has opted to voluntarily issue a recall of some of its AC adaptors, which have been found to be posing a danger of shocking users.

Anyone with a notebook in the past few years might well remember Sony’s last recall debacle, when batteries manufactured by the Japanese giant were recalled en masse due to the risk of explosion. Back then the losses incurred by a mass recall were considered to be so very high that Sony could very well have been put into a financial situation that would cause it to go out of business.


IE8 is Kinder to Batteries

September 14, 2009

There are all kinds of reasons to choose one browser over another, speed, familiarity, user interface, security and personal preference (the list goes on and on) but the one people seldom consider is battery life. Apparently, it’s an area in which Internet Explorer 8 excels.

The folks over at AnandTech sat down with two notebooks and a netbook and ran a series of fairly exhaustive tests to see to what extent browser choice effects battery life for those of us into mobile computing. It’s worth noting that there isn’t the vast difference you might imagine between browsers, but that there was a noticeable difference at all will be enough to impress upon some the need to carefully choose their browser. Internet Explorer beat stiff competition from Firefox (with Adblock installed), Google Chrome, Opera and Safari, which turned out to be significantly less impressive.
