MacBook Air battery replacement not so tricky

Much has been made of the shortcomings of the MacBook Air's battery not being a user-replacable part. But new reports suggest all that's needed for a battery swap is one screwdriver and a few minutes.

The battery is revealed by removing the Philips head screws and lifting off the bottom cover. The same screwdriver can then be used to release the battery from the MacBook Air before unplugging it.

Citing "people familiar with" the MacBook Air, AppleInsider claims the job can be done in "as little as three minutes" and suggests the service will eventually be offered at Apple Stores in addition to the announced mail-in service.

Tech-Ex goes a step further, claiming an Apple Store employee described the 'unscrew, unscrew, unplug' process and said it will be available in store.

You probably won't want to go through this rigmarole on a tray table in economy, so it does not address the needs of long-haul air travellers. Still, there's always Apple's MagSafe Airline Power Adaptor for those flying in the front of the plane.

Assuming these reports are true, what is important is that MacBook Air owners won't need to be without their computer for a week when their batteries eventually fail. Furthermore, an easily replaced battery means aftermarket suppliers will almost certainly join the party, widening the availability and possibly providing flexibility in terms of battery capacity and price - at least after the warranty and optional AppleCare coverage has run out.

Now’s the Time for 400G Migration

The optical fibre community is anxiously awaiting the benefits that 400G capacity per wavelength will bring to existing and future fibre optic networks.

Nearly every business wants to leverage the latest in digital offerings to remain competitive in their respective markets and to provide support for fast and ever-increasing demands for data capacity. 400G is the answer.

Initial challenges are associated with supporting such project and upgrades to fulfil the promise of higher-capacity transport.

The foundation of optical networking infrastructure includes coherent optical transceivers and digital signal processing (DSP), mux/demux, ROADM, and optical amplifiers, all of which must be able to support 400G capacity.

With today’s proprietary power-hungry and high cost transceivers and DSP, how is migration to 400G networks going to be a viable option?

PacketLight's next-generation standardised solutions may be the answer. Click below to read the full article.
