Acer issues recall for some Aspire laptops

by Laura June posted Oct 10th 2009 at 3:32PM

Acer's issued a voluntary recall for some of its Aspire laptops -- all of which were manufactured before September 15th of this year. It seems that some of them are experiencing an overheat of the microphone cable after "repeated" and "extreme" pressure is applied to the left palm rest. The affected models include the AS3410, AS3810T, AS3810TG, AS3810TZ and AS3810TZG. Acer's set up a website where you can enter the serial number of your device to see if yours might be one of the affected.

Walmart expands Durabrand DVD player recall to 4.2 million

by Laura June posted Sep 1st 2009 at 2:33PM

You know what they say about getting what you pay for? Well, the adage has turned out to be truer than normal in this case. Walmart, which sold some uber-cheap (like, $18 - $29 cheap) Durabrand DVD players in the US and the UK, recently issued a recall in the US for 1.5 million of the units due to 12 reported cases of overheating. The malfunctions caused various degrees of property damage, but no injuries, and now, as a result of several more reported cases of the same issue, the recall has been upped to cover 4.2 million devices. The recall, which originally covered only the silver units sold, has now been expanded to cover both the pink and purple DVD players which were sold between January 2006 and July 2009 exclusively at Walmart stores in the US ~~and Walmart-owned ASDA stores in the UK~~ -- Wallmart reached out to let us know that the players sold in the UK were actually a different spec, and thus not a part of the recall. Seriously, this just leaves us wondering: how many of these bad boys did they sell?

Are iPhones burning up in the infernos of processor overtaxation, or is it all a big misunderstanding?

by Paul Miller posted Jul 6th 2009 at 11:11AM

Apple hasn't ever been great at this whole "heat dissipation" thing, but some new developments in the supposed overheating iPhone scandal of 2009 have us wondering how widespread or reproducible these problems might be. Here are a few semi-facts we've managed to amass:

Somebody's white iPhone 3GS grew some ugly brown markings during heavy use.
A new development is saying that the discoloration came from a case (pictured), not from cooking the plastic.
More users than usual have been reporting an overheated iPhone error after the 3.0 update, but as Apple's support documentation points out, this could just be from the time of year (summer, in case you haven't been outside lately).
There isn't a large mass of evidence denoting a major fault to the 3GS, 3.0 or chintzy white leather cases.

So, all that said, what's been your experience?

Apple blames hot iPhones on the weather, others find oleophobic screen to be fleeting?

by Paul Miller posted Jul 4th 2009 at 10:10PM

Don't worry, everybody, your iPhone baking itself to a crisp is no cause for panic, now that Apple has found the culprit: the weather and your heartless negligence. Apparently you've been leaving your brand new iPhone 3GS in a hot car, and the warm sensation you feel any time you hold the phone has nothing to do with beefed up processors or inadequate cooling. Phew, glad that's all sorted and now nobody will have any problems with self-destructive iPhones they paid hundreds of dollars for. Besides, it serves you right.

Meanwhile, hapless Samsas Traum has found a problem of his own (pictured) that's sure to be blamed on some other act of god in the near future by Apple's spin team: the oleophobic coating is getting rubbed right off his screen. Apparently he has a bit of a fondness for a certain "Flick Fishing" app, which explains the highly localized nature of his oleophobic destruction. We haven't heard many other reports of a similar nature, but we'll keep an eye out for telltale Tap Tap Revenge markings on the iPhones of our rhythm-addled loved ones.

[Thanks, Rafa]

White iPhone 3GS reportedly overheats, turns a browner shade of white

by Laura June posted Jun 26th 2009 at 4:55PM

Right after its launch, we noted the sundry problems reported by new iPhone 3GS owners, but this is the first time we've heard tell of this specific one... and it seems like a doozy. It's unclear exactly what caused this, but what is apparent is an unattractive, brownish / pinkish discoloration on the above handset. The user claims it was caused by overheating during a period of using the GPS and 3G of the phone. Either way, it looks pretty crummy now, doesn't it? What about the rest of you with new, white iPhones? Anything to report? One more shot of this looker after the break.

HTC Touch Pro battery goes rogue, lights up an otherwise fine pair of pants

by Darren Murph posted May 21st 2009 at 10:04AM

Just a note to everyone who carries around a spare smartphone Li-ion in their rear pocket: buy thicker underwear. The scene you see above was all caused by an obviously volatile HTC Touch Pro battery, one that the pants-wearer claims is an authentic HTC cell and not a cheap-o alternative from eBay. As the story goes, a foul odor led him to a laundry pile, where he uncovered eight moist socks, a torched battery and a ruined pair of pants. Look, we're glad this guy's okay and all, but seriously, can you imagine what this testy little thing would've done when tossed into the dryer? It's a blessing in disguise, kiddo.

Ionic cooling system adapted for laptop use, scalded legs cautiously rejoice

by Darren Murph posted May 21st 2009 at 7:41AM

To be totally candid, we can't even utter the word "ionic" without thinking of Sharper Image, but the concept here actually seems like one that just might benefit the public at large... or at least those of us forced to cook our upper legs on a daily basis. San Jose-based Tessera, in cooperation with the University of Washington, has adapted an ionic cooling system for use in everyday laptops. The magic elixir consists of two electrodes, one of which is used to ionize air molecules such as nitrogen, while the other acts as a receiver for those molecules. According to reports, this method can extract around 30 percent more heat from a lap burner than the traditional "fan and more fans" approach. Still, a major obstacle remains in terms of ensuring that the electrodes remain reliable throughout the life of a laptop, but if Tessera has its druthers, some form of the system will be commercialized next year.

70,000 HP laptop batteries recalled due to fire hazard

by Darren Murph posted May 14th 2009 at 3:13PM

It's been quite awhile since we've seen a major recall surrounding volatile laptop batteries, but it looks as if HP is the company bringing the topic back to the forefront. Announced today, the US Consumer Product Safety Commission and Health Canada, in cooperation with Hewlett-Packard, has issued a voluntary recall of about 70,000 Li-ion batteries. Reportedly, these cells can "overheat, posing a fire and burn hazard to consumers," and so far, the firm and CPSC have received two separate reports of batteries that have overheated and ruptured, resulting in -- wait for it -- "flames / fire that caused minor property damage." For a look at what units are affected, head on past the break -- oh, and if you're reading this on an HP lappie right now, go ahead and grab the fire extinguisher just in case.

New cooling material keeps heat down in densely packed electronics

by Darren Murph posted Apr 9th 2009 at 3:17AM

Oh sure, liquid cooling rigs are all the rage, but they aren't too useful within minuscule things like netbooks, MIDs and pocket projectors. The always churning minds over at Fraunhofer-Gesellschaft are already on the issue, recently conjuring up a new material designed to "efficiently dissipate heat even in devices with densely packed components and that can give increasingly miniaturized electronics a longer life." Researchers at the entity's Institute for Manufacturing Engineering and Applied Materials Research have teamed with gurus from Siemens and Plansee to create the substance as part of the EU project "ExtreMat." Unfortunately, details beyond that are few and far between, but given that demonstrations have reportedly "already been produced," we'd say it's well on its way to infiltrating things far smaller than your mind can grasp.

Apple firmware update aims to fix vertical line issues on 17-inch MBP

by Darren Murph posted Mar 25th 2009 at 7:59PM

Apple's latest firmware update for the recently shipped 17-inch MacBook Pro sure is light on details, but one thing's for sure: it reportedly nixes those weird vertical line issues that have plagued so many. Unfortunately, the "MacBook Pro Graphics Firmware Update 1.0" doesn't point out whether it was an overheating problem or a GeForce 9600M quirk that was wreaking havoc, but so long as it works, we guess it matters not. Hit up your Software Update when you get enough courage to suck down 770KB of problem-solving goodness.

NTT DoCoMo halts BlackBerry Bold sales after reports of overheating

by Donald Melanson posted Feb 27th 2009 at 10:58AM

It's apparently not quite the same fire hazard that the truth in advertising standard-bearer Quickfire is, but NTT DoCoMo doesn't seem to be taking any chances with its newly-launched BlackBerry Bold, with the Japanese carrier now suspending sales of the smartphone after some reports of it getting a bit too toasty for comfort. Apparently, some 30 users reported that the keyboard "heated up" while the phone was recharging, although it's not clear if that's due to the charger or the handset itself. For its part, RIM says that the issue "appears to be specifically limited to the BlackBerry Bold devices sold in Japan," and that expects to be able to fix the problem and resume sales of the Bold "shortly." In the meantime, stay frosty, Japan.

NVIDIA reportedly urging customers to buy new problem-free GPUs

by Darren Murph posted Dec 26th 2008 at 4:08PM

NVIDIA has yet to step in and confirm this publicly, but a purported leaked memo from the outfit has been posted over at VR-Zone. What's it say, you ask? Only that the company "strongly recommends that customers transition to the latest revision of the NB8E-SET GPUs as soon as possible." Said revision taps a new Hitachi underfill packaging material that "improves product quality and enhances operating life by improved thermal cycling reliability." If you'll recall, certain PC vendors such as Dell issued their own firmware updates to combat the weak packaging set in the chip maker's faulty GPUs earlier this year, but it appears that NVIDIA's solution is to just let bygones be bygones and get on with the new and improved.

Recalled: 35,000 volatile Sony batteries in Dell / HP / Toshiba laptops

by Darren Murph posted Oct 30th 2008 at 5:25PM

Ruh roh. We're really, really hoping this isn't just the first of another long string of laptop battery recalls, but the US Consumer Product Safety Commission, in cooperation with a slew of other outfits, has just announced a voluntary recall of around 35,000 Sony laptop batteries. As you'd expect, the Li-ions in question "can overheat, posing a fire and burn hazard to consumers," and there have already been 19 reports of overheating including 17 reports of flames / fire and two reports of consumers getting mildly burnt. For the full list (and it's pretty long) of affected laptop models from HP / HP Compaq, Toshiba and Dell, be sure to give the read link some serious attention. Oh, and stop using that battery pronto if yours is one of the afflicted.

Sony recalling VAIO TZ models due to overheating risk (Update: now official for US)

by Thomas Ricker posted Sep 4th 2008 at 5:25AM

Own a Sony VAIO TZ? Well, we hate to be the bearers of bad news but your TZ is likely infected by a possibly dangerous manufacturing boo boo. As such, all VAIO TZ models sold between May 2007 and July 2008 are subject to overheating (unrelated to the Lithium Ion battery, mind you) and eligible for free repair. So far, the announcement only covers Japan, we have yet to see any announcements for the rest of world. However, we do have a reader tip saying that US-based Micro Center stores have pulled all the VAIO TZs from its shelves. We'll update you with US and European support information just as soon as it's available.

Update: And here we have it, the official statement of voluntary recall for the US. 73,000 VAIO TZs -- VAIO VGN-TZ100 series, VGN-TZ200 series, VGN-TZ300 series and VGN-TZ2000 series sold between July 2007 and August 2008 -- are affected after 15 reports of overheating resulting in one consumer who suffered a minor burn. Full notice after the break.

Update 2: UK recalled as well. Apparently, more than 200 laptops globally have overheated resulting in seven people suffering "light burns." The recall amounts to about 440,000 laptops.

Purdue researchers want tiny refrigerators cooling your PC

by Darren Murph posted Jul 24th 2008 at 7:02PM

You think your liquid-cooled rig is pretty snazzy, don't you? After Purdue researchers get their technology on the streets, that stuff will seriously look like old hat. The team is working on a "miniature refrigeration system small enough to fit inside laptops and personal computers," which would hopefully boost cooling performance while enabling computers to be smaller. According to Suresh Garimella, they have "a very good handle on the technology," but it's still a ways from being implemented in end products. Don't worry though, we're sure the likes of Alienware and Voodoo PC will have it up as optional equipment just as soon as it clears the quality assurance lab.
