PC Repair Rip-Offs: Don’t Get Gouged by Fix-It Services

December 28th, 2010

Computers don’t always work as they should. Components fail, and operating systems fill up with crap that hinders performance and occasionally brings the whole machine to a halt. Savvy users know that they can fix most PC problems themselves, and use sites like PCWorld.com to find solutions to their tech problems. Those who lack confidence in their tech skills, however, often fall prey to the rapacious tactics of online and local repair shops.

Lest your local geeks-for-hire take you for a ride (or fleece someone you love), we’ve rounded up a representative sampling of typical repair-shop services to help you sort the rip-offs from the reasonable deals.

LaptopIn this article, I’ll explore some of the most common offerings you’ll find at repair shops large and small. These aren’t scams, to be sure–as far as we know, these are all legitimate services from legitimate businesses. But the actual value of these services–relative to the work involved and the likely benefit to the consumer–can be highly questionable in many cases.

Apple expected to release fix for antenna problem

July 5th, 2010

Apple that it will soon release a fix for the antenna problem where the iPhone shows wrong signal strength through signal bars.

Apple said in a letter, “Upon investigation, we were stunned to find that the formula we use to calculate how many bars of signal strength to display is totally wrong. Our formula, in many instances, mistakenly displays two more bars than it should for a given signal strength.”

Experts and tech enthusiasts were earlier debating if the flaw is with the hardware design on the new Os from the company. The device features two antennas, one of the left for of the phone for Bluetooth and Wi-Fi and the one on the right for cellular signal. The signals get affected by the manner in which the phone is held.

Now the company is preparing the fix for the issue as it faces lawsuits from some of its angry customers. “We will issue a free software update within a few weeks that incorporates the corrected formula. Since this mistake has been present since the original iPhone, this software update will also be available for the iPhone 3GS and iPhone 3G,” it said.

The problem surfaced when customers started complaining about weakening signal when the deviceis held in a particular way. Apple soon acknowledged the issue and issued a statement, “Gripping any phone will result in some attenuation of its antenna performance with certain places being worse than others depending on the placement of the antennas.”

The statement continued, “This is a fact of life for every wireless phone. If you ever experience this on your Phone 4, avoid gripping it in the lower left corner in a way that covers both sides of the black strip in the metal band, or simply use one of many available cases.”

Apple iPhone is available in some countries including US, UK, France, Germany and Japan and will soon be launched in other countries around the world. Apple intends to fix the problem before it reaches more customers in other countries.

“For the vast majority of users who have not been troubled by this issue, this software update will only make your bars more accurate. For those who have had concerns, we apologise for any anxiety we may have caused,” it said.

IFixit,iPad,hardware

April 4th, 2010

The iPad’s design is a melding of the iPhone’s circuitry and the MacBook Pro Unibody’s svelte machined aluminum casing.

Our findings?
The iPad’s battery has 5.5x the capacity of the battery in the iPhone! The iPad actually has two batteries wired in parallel, for a total of 24.8 Watt-hours.

On average, the iPad sips just 2.5 Watts. That’s 1/5 the power of a compact fluorescent bulb!

The rear case is machined from a single billet of aluminum, increasing weight but greatly improving the rigidity of the device.

The empty void in the upper right corner is where the cellular communications board would go in the 3G iPad.

The A4 is a Package-on-Package (PoP), with at least three layers of circuitry layered on top of each other. A4 is packaged just like the iPhone processors, microprocessor in one package and two memory modules in the other package. They’re all sandwiched together in a very nice and thin PoP.

The iPad RAM is INSIDE the A4 processor package. Confirming this took quite a bit of sleuthing: we had to partner with Chipworks to X-ray the processor. The X-ray revealed two layers of RAM. In addition to the ARM processor, the A4 package contains two stacked Samsung dies.

We will be releasing a detailed analysis of the A4 in conjunction with Chipworks in a few days.

The rumored slot for a camera is actually taken up by the ambient light sensor.

The glass panel is quite thick: about 1.18 mm, compared to the iPhone’s 1.02 mm thick glass. This is necessitated by the panel’s large size.

The touch circuit design is more similar to the old 2G and early 3G iPhones than the current 3GS. Chipworks informed us that “there is so much room in the iPad that Apple didn’t need to use small chips, just the right ones and cheap ones.”
