Speed bump (speed bump) American computer journalists call upgrade computers in which in addition to performance and several other parameters did not change. With them, usually not too much of a problem. But this time… In one of the comments Steve jobs has called a “good Manager”. I don’t think so. He was not “just a Manager” – he was a filter, a generator of ideas and a lot more. As a Manager he’s been different.
To create something “insanely great” and to correctly manage the company is not the same thing. In the era of Steve jobs “a good Manager” was Tim cook. And even during the most risky maneuvers, the company worked flawlessly.
In 2011, Steve jobs was never able to fully take the company under their control, and Tim cook could not perform their duties in full. Perhaps one of the reasons for problems with the MacBook Pro released October 24, 2011, it was just that. This assumption.
Problem with GPUs from AMD (which overheated and failed) to detect early and to take action. To spend more time and effort to it – especially since something like this has happened. If these measures delayed the release of the new MacBook Pro in light of the company would have suffered much less damage.
Screen of death:
To convince AMD of the existence of a problem may not be too easy – but to consider the likelihood of overheating of the graphics in the design of the computer was possible. For example, do not solder it to the motherboard (to facilitate replacement), to embed sensors overheating, to increase the cooling – it would cost a lot, but what happened has cost significantly more.
The party who tested it was good, but whether it was necessary to confine her?
Did not finish…
24 Oct 2011, Monday, online store closed for updating, and when it become available again in the list of the new 13-, 15 – and 17-inch MacBook Pro.
The set of initial configurations were exactly the same as before. The same three models (with exactly the same identifier – MacBookPro8,1, MacBookPro8,2 and MacBookPro8,3), only the clock frequency has increased (slightly), one and a half times increased the volume of drives, and the 15 – inch and 17-inch models now installed a more powerful discrete graphics from AMD. Prices remained the same.
The 13-inch model
13-inch MacBook Pro (MacBookPro8,1) was only integrated graphics, Intel HD Graphics 3000, which is reserved for their needs 384 MB total RAM, if its volume was less than 8 Gigabytes and 512 Megabytes if the amount was equal to or greater than 8 Gigabytes.
In the initial configuration of all 13-inch variants included 4 GB PC3-10600 (1333 MHz) DDR3 SDRAM, according to Apple the maximum amount of which was limited to 8 Gigabytes. In fact, with 16 Gigabytes had no problems.
There were two options: with dual-core Intel Core i5 2.4 GHz (i5-2435M), cache third level 3 MB and dual-core Intel Core i7 2.8 GHz (i7-2640M), cache in the third level 4 MB. Both processors supported all the “Goodies” Sandy Bridge, including Turbo Boost 2.0. The clock frequency of the i5-2435M could be dynamically enlarged up to 3.0 GHz, and the i7-2640M up to 3.5 GHz.
In the version with Core i5 is installed in the hard disk of 500 GB (5 400 rpm), it can be replaced by:
— HD 750 GB (5 400 rpm) for $ 100;
— SSD volume of 128 GB for $ 200;
— SSD 256 GB for $ 600;
— SSD 512 GB for 1 $ 200.
In the February version was a disk of 320 GB (5 400 rpm).
In the version with Core i7 installed disk 750 GB (5 400 rpm). In the February “big” was the disk of 500 GB. Instead of disk 750 GB can be ordered:
— SSD volume of 128 GB for $ 100;
— SSD 256 GB for $ 500;
— SSD 512 GB for 1 $ 100.
Outside of the online store of the SSD were cheaper, at least a third.
The 13-inch model of the problem with discrete graphics is not touched, for obvious reasons. Cons sometimes turn into advantages.
In all other respects the model was similar to February.
15 – inch and 17-inch models
Models were two: MacBookPro8,2 (15-inch MacBook Pro) and MacBookPro8,3(17-inch MacBook Pro). All variants of both models is 4-core.
In online store there were two initial configuration MacBookPro8,2:
— “economy” Intel Core i7 2.2 GHz (i7-2675QM), cache third level 6 MB. Turbo-max is 3.1 GHz. Disk 500 GB (5 400 rpm). Option of processor this option was not;
— the “business-class” Intel Core i7 2.4 GHz (i7-2760QM), cache third level 6 MB, turbo max 3.5 GHz and the possibility of replacing the processor Intel Core i7 2.5 GHz (i7-2860QM) scasum the third level is 8 MB, turbo max to 3.6 GHz. The disk is 750 GB.
And one initial configuration MacBookPro8,3, Intel Core i7 2.4 GHz (i7-2760QM), and with the option of replacement with a more powerful Intel Core i7 2.5 GHz (i7-2860QM). Exactly like the 15-inch “business class”.
Everything else, except for graphics cards, all as in the February models.
In the “economy class” – the discrete AMD Radeon HD 6750M and Intel HD Graphics 3000. The first 512 Gigabytes of GDDR5, the second was taken from the total RAM to 384 or 512 MB, depending on its size.
Problem with him, as far as I know, was not.
In the others, but the same Intel HD Graphics 3000, was used and AMD Radeon HD 6770m, also with 1 Gigabyte of GDDR5.
The GPU was soldered to the motherboard, which had to change to a healthy whole.
2 200 owners ruined AMD Radeon HD 6770m, also sent a petition to Apple, which threatened to turn into a lawsuit. Apple did not bring the case to court. Until 2016 free she changed the PCI card in the affected MacBook Pro, and are also reimbursed costs to those who already replaced it at their own expense.
But after 4-6 months, usually the parent map again needed replacement. How much did that cost Apple I don’t know, but affected by the problems were at least tens of thousands (it was shown by 10-15% of the MacBook Pro with AMD Radeon HD 6770m, also), replacement cards cost about $ 500. Damage to the reputation of the company was enormous.
In media appeared reports that the problem was identified on all MacBook Pro (Late 2011), regardless of the model of the GPU (even on the 13-inch), but no one was able to confirm their statements.
