Most APs don't yet support this, but the AIrport Extreme from Apple does. Apple is claiming 450 mb data rates because in a 40mhz channel 5ghz situation, they can use a 3rd spatial stream. Most laptops are 2 spatial stream (Max at 150mb data rate on 2.4ghz, or 300mb on 5ghz (when 40mhz wide channels are enabled). Mobile phones with 802.11n today are usually 1 spatial stream and 1 antenna (Which is why they max at a 65mbps data rate). Aruba APs are mostly 3x3:2 (3 antennas, 3 transmit chains, but still only 2 spatial streams). In fact, most Cisco APs are 3x2:2 (3 antennas, 2 transmit chains, 2 spatial streams).

It does not have an 'Extra' antenna for 802.11, that J3 antenna is hooked into the BCM2070 Bluetooth chip at the bottom of that wireless board, so it's a bluetooth antenna.Īpple is still ahead of the game with a 3x3:3 radio, as most APs (Even Cisco enterprise APs) do not support 3 spatial streams today. There could be more clarity around the wireless card.

I understand that as delivered, the motherboard is designed to work with an optical drive on the optical drive port (3gb/s) & a SSD or HDD on the main 6gb port.ġ) Where's the actual quote of what David Moody said?ģ) Given that he is a hardware executive, is it reasonable that they did a hardware correction, (rather than a software patch)Ĥ) Can we trust that Intel's budget for the recall replaces for full HDD support on the optical drive Cleaver - 2011 MacBook Pro Owners Launch Petition Over Defective GPU By Tyler Lee, on 17:11 PDT Back in 2013, there were growing complaints about how Apple’s early 2011 15-inch and 17-inch MacBook Pros were suffering from issues with its AMD GPUs.

: 'Earlier this year, Intel discovered problems in the chipset of Sandy Bridge processors that were shipping, but Apple vice president of worldwide Mac hardware marketing David Moody told Macworld that the company was using the latest updated versions, which corrected the flaw.'įrom. Also 6 Gbps SATA SSD problems require cable replacement, replacing a PowerBooks hard drive, Motorola Atrix 4G and the future of mobile computing, and more. So I did some digging - the best assurance I can find is on. Many Early 2011 MacBook Pro Problems Addressed in OS X 10.6.7, MacBook Pro GPUs Benchmarked, and More, The Book Review, 2011.03.25. That link shows people have already fitted exiting OptiBay models. they've emailed to say they will know within a few days their official opinions. Actual repair of the MBPs requires reballing the chips (150US repair) but instead Apples drawn no correlation between the 2011 iMacs and the 2011 MBPs, so owners out of warranty have been told.

I've an outstanding request with MCE Technologies asking them to verify. I suppose that shifting the SSD to the OptiBay and adding a HDD would necessitate changing a PRAM / NVRAM setting. The drive is considered user replaceable - such that users can swap either HDD for SSD or (less likely) SSD for HDD - meaning the motherboards must be identical and include the Sudden Motion Sensor. My conclusion / assumption on this is that the SSD models are all build-to-order vs, ready made for the HDDs. That said, I couldn't see a KXM chip on the teardown photos (but didn't find them on past models either.) , the MacBook Pro has in the past featured a Kionix three-axis accelerometer chip, (KXM52-1050), for protecting its HDD. It can also be used to connect computers to external monitors and transfer data at the same time, all with a single cable.According to. Thunderbolt is supposed to transfer data at a rate of 10 gigabits per second. The newest addition to the family is Intel's new high-speed connector technology called Thunderbolt. It features an AMD Radeon HD graphics processor.

The MacBook Pro 15' Early 2011 is one of the first Apple laptops powered by an Intel quad-core i7.

The Unibody revision also introduced some features that were never before seen on an Apple laptop: the inclusion of dual video cards (one for regular use, one for graphics intensive applications), the Mini DisplayPort (which replaced the full-size DVI display connector), and larger hard drive and RAM capacities. Apple did offer a free video card replacement on some mid-2011 iMacs exhibiting similar symptoms, though the cards in the MacBook Pro are different, and recalls as a whole are rare. The MacBook Pro 15' Early 2011 Unibody's case is composed of a single block of aluminum, following the same process of the MacBook Unibody and the MacBook Pro 17' Unibody Repair. MacBooks tend to look very similar, and it's important to know which machine you have before ordering any replacement parts.
