Speaking of that -- did you reboot by any chance? Some video driver bugs show up mainly when the system has been up a long time, and can be cleared away by restarting the OS. (Because they're issues with video card memory allocation, and the longer the system is up the more chances there are for memory management bugs to cause buffers to stomp on each other, or whatever.)

Quick battery-related question. I bought my parents a MacBook Air for their anniversary, but had it delivered to me so I could get it all set up, install a spare copy of Office 2011 I have, etc. Now I want to ship it to them but was wondering - given it might be flown via UPS or FedEx, do I need to drain the battery down at all before shipping it?

Oneiros posted:A while ago I convinced my brother to get a Samsung 830 256GB and he stuck his old spinning drive in an optibay knockoff. I encouraged him to handle the data allocation manually because the Fusion drive thing was new and I was concerned about how little free space the system keeps on the SSD (5 GB?). It was my understanding that running a SSD with that small of a "landing zone" for writes both increases wear and decreases performance, though of course it's still much faster than a HDD. Do SSDs even have wear, what with the whole "no moving parts" business and all? (I honestly dont know)

duck monster posted:Do SSDs even have wear, what with the whole "no moving parts" business and all? (I honestly dont know) Yeah over time the NAND cells become unable to be written. They can be read from practically forever though- so a dead SSD is basically read only storage. A samsung 840 will get around 3 years of use before this happens, larger higher quality drives can last significantly longer. It'll be interesting in the tail end of the decade to see first gen solid states start to die all over the place. 'course the whole thing can gently caress up and trash the data but that's not wear that's just breaking.

japtor posted:Yeah the NAND life has an effect on the read only state too. I think the more exhausted the flash is the shorter the shelf life (unpowered state) is. The one I remember was the Samsung 470 from a few years back. It eventually stopped writing after however many TB at which point the guy pulled it out and put it into storage to check it. I think he checked in a day or two and it was fine, but after leaving it alone for a week or so it was unreadable. Yup. Writing to a flash NAND cell degrades its ability to retain a charge which, of course, encodes the value of the bit(s) stored in the cell. More damage means more electrons "leak" out of the floating gate and increases the likelihood that data becomes corrupt or lost entirely over a shorter period of time.

No, just ship it. It has most likely already flown with a full charge.

Seconded, but don't use any isopropyl percentages below 95%. Amazon has a bunch of these, make sure you get lint-free wipes. On SSD's, I've already seen a lot of first generation PATA ZIF SSD's from first generation MacBook Airs go bad. Most are read only, some just don't work at all anymore.

My mid-2012 Macbook Air is displaying a "Service Battery" warning. The battery does seem to be way shittier now than ever. Checked the Cycle Count, it's at 266. Is that high? I have no idea. I do have AppleCare but didn't memorize the terms on batteries. Any anecdotes on what dealing with this is like at the Apple store? Can they just replace the battery? If not, it's a custom build so hopefully getting a replacement wouldn't take too long. I have to finish developing an app by the end of the month, so if there's a chance it could be a whole ordeal I'll probably wait until it's complete just to be safe. Thanks in advance.

Past that they'd probably charge $109-129 or whatever. The actual task of swapping the battery is pretty quick but it is kind of delicate as the battery is essentially just one big gel pack encapsulated in just enough plastic to keep the innards in place and not blast open if dropped.

It's also worth noting that the more reputable batteries are in the $90-$100 range, so the apple full service option is not much more expensive. The newer batteries are rated for 1000 full discharge cycles, still holding 80% of the full charge.

It's a little over a year old, but I did buy 3 years of AppleCare. It stays plugged in most of the time (fully charged), otherwise I grind it down to 20% or so before letting it fully charge. There are several times where I pass out and it just dies overnight.

Check to see if the alert is still there after using the computer unplugged for a while. I remember getting one in the toolbar battery menu a few months back (2011 Air) and it went away on its own after about 5 minutes. Haven't seen one since. You could also try rebooting and seeing if that makes any difference. (If you've got AppleCare and a fruit stand nearby I'd just take it in).

A good amount of the online tips are bunk such as warning about charging too high eventually destroying battery capacity. So make sure you never charge your laptop above 80%! Things like battery electronics improved over the years to charge much more carefully at the high state of charge through a process called adaptive charging.

Escorted may have been to strong a word, but the manager came out immediately and said, "This has entered legal territory, you need to leave the store right now and call Apple Legal, we can no longer help you here," and walked me out. It's not like they called security to haul me out or anything. I posted about it in this thread when it happened (and the previous and subsequent trips to the store to get my Mini fixed). I was perfectly polite and not a douche at all - the Genius was very apologetic when the manager instantly turned sour and, when I came back a week or two later when the manager wasn't around, we figured out a way to consistently reproduce the issue and he was finally able to get authorization to do another repair (it was my 6th trip in for that issue and they'd attempted 3 different hardware replacements already). Edit: FWIW, it was the cable connecting the bluetooth/wifi card to the logic board that was causing kernel panics. They'd replaced almost all the other hardware, including the logic board and the bluetooth/wifi card, but of course hadn't thought to change out the cable. When the store gave up (and refused to replace the Mini outright) I called AppleCare on the phone and they told me, "Everything in that computer is brand new now - the panics must be a software issue and we will not swap out a computer for a software issue." It was panicking on a clean install of OS X with no third-party software installed. Hence my attempt at mentioning the lemon law...

A full discharge (i.e. 100% to zero in one step) supposedly may help calibrate the percent battery indicator in the OS, but for modern batteries a full discharge is really just a cumulative 100% of activity. Five percent of discharge and recharge every day for 20 days is a full cycle, which is why just unplugging it occasionally is all you need to do.

Yeah, because backups don't exist and shouldn't be made, ever. The cloud also doesn't exist. It's also not possible to put the essential data on external disks because those are as big as refrigerators. I'm sure there are use cases where SSDs don't make sense, but for the majority of users it works and they'll keep getting better.

Don't use the mac store ever for repairs if theres an authorized third party repairer. I've had far too much troubles with the apple store not respecting Australian law regarding repairs. All devices in australia have life time guarantees for manufacturer defects, they can't impose their own arbitrary conditions (Its determined by law, not contracts) and so on, and the courts here take a *very* dim view of fine-print shenanigcans. Apple are constantly just straight out violating australian laws, and unfortunately the penalties for minor violations means they just ignore it until they are ordered to repair something, and as I discovered the hard way, thats a long process. Until I started going to a local authorized repairer, and the guy there is a nerd and has no incentive at all to arbitarily flunk repairs because he actually wants to get paid. He even had the "water damage" ruling by apple reversed after he noted NONE of the moisture sensors where tripped and that the apple guy *couldnt* have examined the part he did, because the seal was untampered. A friend of mine recently quit the apple store over one of the guys who would flunk stuff for water damage to avoid repairs despite knowing it wasnt water damaged. Guess who had flunked mine? duck monster fucked around with this message at 07:24 on Sep 12, 2013 |

I actually did return my iMac with the scratched cover glass to the store. They immediately put a new glass on it, only to now have introduced a "dead pixel" (which looks more like a cluster of pixels or dirt) in the middle of the display. They tried to play it down, but left the decision up to me. So it's on to display panel #5! (Out of curiosity, is it even possible that dead pixels can be added later on? It really looks more like some dirt.) In any event, the conversation never got to the word "lemon" and I never spoke to a manager, so all is well. At least in my particular store, they've never taken more than a minute to acknowledge any problems I had and they've always been nice enough.
