Smart battery finished polling type


Mac Os не запускается. smartbattery: finished polling type 4

Andrey | 09.01.2017 | Все о гаджетах |

В один из дней мне принесли MacBook последнего поколения, который не запускается. Зависает во время загрузки и все. По сути проблема стандартная, скорее всего битая файловая структура диска, и есть два варианта:

  • Удасться починить и тогда компьютер запуститься
  • Не удасться починить. Тогда надо будет копировать папку пользователя и переустанавливать систему.

Но изначально возникли проблемы, удерживая кнопки cmd + R чтобы загрузиться в recovery mode и запустить дисковую утилиту я понял что в рекавери компьютер тоже не хочет грузиться. Но ничего страшного, пробуем загрузиться через интернет. Зажимаем во время включения opt+cmd+R и видим тоже самое — не можем загрузиться.

На самом деле, чтобы проверить файловую структуру диска, совершенно не обязательно загружаться в рекавери, можно загрузиться в single-user mode. Для тех кто не знает, это режим с помощью которого мы можем используя командную строку что-то быстро исправить. Загрузился в  single-user проверил файловую струкруту диска, права доступа — все ок, нареканий нету. Странно…

Загружаемся в verbose boot. Это режим который показывает что именно сейчас происходит. Видим что загрузка затыкается на строке

Ага. Ясно. Принудительно выключаем компьютер кнопкой включения. Скорее всего проблема в SMC. Нам надо сбросить параметры управления контроллера системы. Для этого зажимаем Shift + Control + Option и включаем компьютер.

Спустя пару секунд, после перезагрузки, компьютер запускает в штатном режиме.

На этом все, но если  вас возникли вопросы или пожелания пишите в комментариях, попробую вам помочь.

Sierra is not installing - Apple Community

Hello Fellows!

I am completely stuck in the middle of nowhere. Trying since weeks to upgrading a Mac Air to Sierra but it stuck on the big apple screen with the installation status bar fully completed. I kept it for days with no results.

By using Command+V (verbose mode) I can see the mac doing this:

- AppleKeyStore: operation failed ........

- AppleMCP89TMS: powerGettingDown (0): Done

- SmartBattery: finished polling type 1

- busy timeout [0]......

- SmartBattery: finished polling type 1

- busy timeout [1]......

- IOConsoleUsers: time(0) 0->0, lin 0, link 1

(It is just looping at the SmartBattery, not going forward)

So, from the Recovery mode I tried to Reinstall OSX though the result was exactly the same as above.

Then, I tried from another Mac to create a bootable USB key from my Mac, and followed the instruction here:

Create a bootable installer for macOS - Apple Support

Downloaded Sierra from Apple Store

Mounted a new USB key 32Gb

Went into terminal and lunched the command:

sudo /Applications/Install\ macOS\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/XXXX --applicationpath /Applications/Install\ macOS\ Sierra.app

(where xxxx is the name of my USB volume)

The command asks for the password, and after entered the admin password... nothing happens... ????

Now, from the Recovery mode, I tried to erase the HD, but I cannot from there.

So, I am installing the OSX on the USB key with the hope to startup the Mac from USB key...wondering

...am wondering if when the installation on the USB key will be competed, I will be able to startup the Mac from the USB key and then to delete the Mac HD and eventually installing Sierra on it?

Apple Smart Battery Case Review: Better Than It Looks

One of the chief complaints about any smartphone is limited battery life. Apple has been more fortunate than other smartphone makers in that many third parties have created battery cases that extend the iPhone's battery life for hours. But now, Apple is getting into the business itself with the Smart Battery Case. This $99 accessory for the iPhone 6 and iPhone 6s has a few advantages over third-party solutions. But when it comes to the area that matters most — providing enough juice to last an entire day — how does it compare to competing products?

Design: My Humps

The iPhone Smart Battery Case has a noticeable hump where the battery resides. While this undoubtedly makes Apple's case less bulky than rival offerings, it's not as elegant as other cases, such as the Mophie Juice Pack Air, whose smooth backside has a more unified look.

(Image credit: Samuel C. Rutherford / Tom's Guide)

The Smart Battery Case is covered in a soft-touch finish, which is not only comfortable to hold, but also helps to keep the iPhone from slipping out of your hand.

(Image credit: Samuel C. Rutherford / Tom's Guide)

The top of the Smart Battery Case is made of a flexible material that bends back to let you insert the iPhone itself. Mophie's Juice Pack (pictured above), which is made of a harder plastic, has a detachable upper section, which makes it easier to insert and remove your iPhone.

I like that the Smart Battery Case has a Lightning connector on the outside; every other battery case I've seen has to rely on a micro-USB connector. This lets you use the iPhone with other accessories while it's still in the Smart Battery Case; with others, you have to remove the iPhone first.

MORE: Best Smartphones

Weighing 3.5 ounces and measuring 5.9 x 2.8 x 0.5 inches, the Smart Battery Case is slightly heavier but a smidge smaller than the Mophie Juice Pack Air (3.6 ounces, 6.1 x 2.9 x 0.6 inches). Apple's case is available in either white or gray, while the Juice Pack Air comes in nine different colors: black, white, rose gold, gold, purple, green, blue, pink or red.

Features

The Smart Battery Case doesn't come with a headphone jack extension. If you don't have this little accessory, which comes with just about every battery case, good luck trying to get anything other than Apple's own headphones into the iPhone.

(Image credit: Samuel C. Rutherford / Tom's Guide)

Cleverly, when the iPhone is inserted into the Smart Battery Case, you can look in the Notifications pane to see the charge level of the batteries for both the iPhone and the Case. However, unlike the Mophie and other battery cases, there's no indicator on the outside of the Smart Battery Case, nor is there a way to turn off the Case when the iPhone is inside and use just the iPhone's battery.

Performance

Apple claims the Smart Battery Case's 1,877-mAh battery will last up to 18 hours over LTE when using the Internet.

On the Laptop Mag Battery Test (Web surfing over LTE with the brightness set to 150 nits), the iPhone 6s and the Smart Battery Case lasted a combined 18 hours and 50 minutes, before stopping at 6 percent. Without the case, the iPhone lasted 5 hours and 52 minutes.

MORE: Best Unlocked Smartphones

The Mophie Juice Pack Air has a 2,750-mAh battery that the company says will provide more than 100 percent extra battery life. We will update this review with those results, and reserve the right to change the rating of this review.

Is the Smart Battery Case a tacit admission by Apple that the iPhone doesn't last long enough? Maybe, but the excellent endurance offered by the Smart Case helps make up for that deficiency.

(Image credit: Samuel C. Rutherford / Tom's Guide)

While I like that Apple's case has a Lightning connector and shows the battery life of both the case and the phone in the Notifications pane, its humplike backside kills the elegance of the iPhone. If you don't mind the looks, though, the Smart Battery Case will keep your iPhone 6 or iPhone 6s going long after the day is done.

Polarizing Options - Choosing a Battery Charger

Your battery went flat, it is dead and you need to get to work in the morning. After rummaging around in the cabinet, you drag out hulking metal box with two switches, a set of wire clamps and a wall cord. You battery charger looks just like the one your grandpa used 40 years ago on his Buick. Heck, this might actually BE the one that charged the old Buick every winter’s eve. You shake off the dust, plug it in and are greeted with the soft hum of the transformer. No, this isn’t Optimus Prime; it is the part that makes the charger work. You nod you head in satisfaction and head back into the house. A few hours later you come out to check on things. One quick sniff and you know something isn’t right. A look into the engine bay and your suspicions are confirmed, that old battery charger has overcharged the battery, which is now boiling over, sending the smell of sulfur wafting through the air. Now you’ve done it, time for a new battery.

This story is as old as that same battery charger technology, but it doesn’t have to be that way. Battery chargers have changed quite a bit from the days of the uncontrolled, full amperage battery boilers of the yesterday. Today’s modern charger is different. Today’s modern charger is smart. What exactly does that mean? Much like your cellphone or TV, these battery chargers are microprocessor controlled.

Automatic Operation

The reason that those old-style chargers boil the electrolytes in a typical flooded battery is because they don’t shut off when the battery has reached capacity. This can be controlled through several methods. Solid state controls use resistors and capacitors to measure the voltage on the battery. These work, but they can fail, leaving your battery melted inside your car.

A microprocessor is essentially a computer for you battery charger. Where a solid-state charger puts amperage to the battery until it shuts off, the smart charger operates in a much different manner. Rather than simply blasting the voltage charge to the battery, the smart charger utilizes a multi-phase charging cycle similar to what the alternator does in the car. Pro-Logix smart chargers from SOLAR use a 7-phase cycle to achieve maximum charging efficiency.

Phase 1:  Energizing

This is the first stage, where the system is powering up, preparing the charger to work. Output is roughly 6 amps, while the voltage increases from 4 volts to 7.

Phase 2:  Fast Charge

The amperage is increased to 20 (depending on the model), and voltage increases, maxing out at 14.4 volts. This is the longest phase and puts the majority of the charge into the battery.

Phase 3:  Absorption

If you just turn off the charger, much of the power charges gets lost. This is because the plates and electrolytes in the battery are a chemical process, it takes time to absorb all of the energy from the charge. The absorption phase slowly reduces voltage and amperage, allowing the battery to work, retaining more of the fast charge.

Phase 4:  Completion

This is the stage in which the charging cycle is finished, and the cells have equalized.

The next 3 stages are part of the maintenance cycle.

Phase 5:  Resting

The battery and charger go into a rest mode; there is no voltage or amperage running through the charger in this phase. This allows both components (battery and charger) to cool down, as well as reduces the possibility of drying out the battery during extended storage.

Phase 6:  Exercising

At this point, the battery is fully charged at rest, but what about with a load? The charger will run a series of load tests, working the battery to find out if it is holding the charge. This also prepares the battery for the restoration phase.

Phase 7:  Restoring

After the exercises, the battery’s charge will be reduced, so the charger runs through a charging cycle that is similar to the fast charge, but reduced in strength. This maintenance routing ensures that the battery is at full capacity and ready to be put back into service.

This graph shows the phase cycle of the Pro-Logix chargers

Chances are when you need a battery charger, you are in a situation where you need to get your battery charged and it needs to happen quickly. A smart charger will compensate for ambient temperature, battery condition, and other factors to ensure that your battery gets charge quickly and charged safely, ensuring that it lasts.

Battery Types

We covered the different types of batteries in our “Batteries 101 – A guide to automotive batteries” article a few months back.  If you have multiple battery-operated vehicles, then you need a charger that is capable of charging all types of batteries. While flooded batteries are still the most common automotive battery, AGM (absorbed glass mat) and gel cell batteries are becoming more commonplace. A standard solid-state charger does not work very well for these types of batteries, in fact, they can damage them internally.

Other types of vehicles, such as motorcycle, ATVs, watercraft and lawn mowers often have specialized batteries that are not easily charged with a bargain-store charger either. The smart charger is capable of handling any lead-acid battery, big or small, 6 or 12-volt, of any type currently on the market.

Battery Testing

The last thing you want to do is waste time charging a battery with a bad cell inside. The Pro-Logix chargers from SOLAR have internal testing mechanisms that check the batter for bad cells, sulfation (this is what happens when a battery is used when not fully charged), or deeply discharged batteries.

Deeply discharged batteries must be charged slower than a mildly-discharged battery in order to achieve full charge. “Deeply discharged” is considered having less than 10 volts or lower than 50% of its capacity. If a battery is so discharged that it has below 6 volts, some battery chargers won’t even recognize that a battery is connected and a second battery must be connected to get the charger to cycle.

Battery Charging Safety

Smart chargers are smart, so smart that they know when the battery is connected correctly. Hook it up wrong, and it will tell you.

Battery Maintenance

Unlike a solid-state charger, the smart charger is also the perfect solution for long-term storage. Over time, batteries will lose their charge naturally. With a maintenance charger connected, the battery will remain fresh during storage so that when it is time to ride, the battery is good to go.

Battery Charging Boost Mode

For those times that you just have to get the car going and don’t have time to let the battery charge, there is boost mode. Depending on the charger, you can get 20 amps on up to 250 amps of engine-cranking amperage for getting your car started and down the road. Just don’t forget to plug it in when you get home for a proper charge cycle.

How to choose a charger

You know you need a high-quality battery charger, but you don’t know which one to choose. We have broken them down into several categories that will help you decide exactly what you need. All of the Pro-Logix chargers are capable of charging all types of batteries and each one has the 7-phase maintenance cycle to ensure that the battery it is connected to lasts as long as possible.

For the casual user, the entry-level charger will be sufficient. These are available in 10 and 20-amp versions.

Casual Battery Charger User

The casual user is defined as owning 1-2 vehicles, living in a moderate climate, where both vehicles are driven daily. Driving your car every day helps maintain the battery, which reduces the need for regular use of a battery charger. The Pro-Logix PL2310 or PL2320 are perfect for the casual user to provide a maintenance charge for vehicles, personal watercraft, ATVs, and battery-powered lawn equipment when needed. The PL2310 has 2, 6, and 10-amp charge modes, where the PL2320 steps up the amperage to 20 amps for a faster charge, perfect for larger batteries and heavy-duty batteries such as lawn equipment and PWC/ATVs where you need a full battery in relatively short charge time.

If you have ever needed to get your vehicle started with a discharged battery, then an upgraded charger with Boost Mode is the one for you.

Casual+ Battery Charger User

When you need emergency starting power, boost mode is what you want. The Casual Plus user have one or more vehicles that sits unused for longer that a few days at a time, owns multiple PWCs, ATVs or battery-powered lawn equipment. Just like the casual chargers, there is a 10-amp and 20-amp version, however the PL2510 (10-amp) and PL2520 (20-amp) feature a 55-amp and 100-amp engine starting boost mode. These chargers are what you want if you live in an extreme-climate area where the freezing cold can zap your battery’s charge overnight and you need to get to work. Simply connect the charger, fire it up in Boost mode, give it a few minutes, and then hit the key to start the engine. These chargers are also perfect for starting those vehicles that sit for months at a time, such as ATVs, PWCs, and battery-powered lawn equipment.

If you have lots of cars, or are an automotive professional, then a wheeled charger is absolutely the best option. This fully-functional unit has 250 amps of starting power!

Professional Battery Charger User

If you run a shop or just own a lot of vehicles that use batteries, then you might want to consider a wheeled charger, such as the Pro-Logix PL3730. This charger features 5, 15, 40, and 60 amps in standard charge mode, with a 275-amp boost mode for starting vehicles with completely discharged batteries.

The Pro-Logix PL2520 experience

We put the Pro-Logix PL2520 charger to the test. We had a battery that had been causing some problems for its owner. The alternator is not working properly and the battery subsequently went flat. The battery was put on the bench for an overnight charging cycle. Here is how that went:

First, the battery was tested with a voltmeter. 11.72 volts at rest, but there was no enough energy stored to crank the engine.

The PL2520 was connected and it recognized the battery and showed the current charge on the display.

The PL2520 has multiple settings for boost mode, voltage and amperage, as well as battery type.

You can choose several variables for the charging rate, voltage and battery type. We put the charger into 10-amp, 12-volt, Standard battery configuration as we had time for an overnight charge. If we needed the battery quickly, 20-amp would be faster, and boost mode would start the car, but this battery needed a full charging cycle as the alternator needs replaced in the car.

You have to push start.

The charger does not begin the cycle until you hit the start button. This is part of the safety features, if you were to touch the clamps together while connecting the battery, it won’t blow the circuits.

Green light means it is done!

When the charging cycle is complete, the charger illuminates the green “Charging Complete” light. There are no dials or gauges to decipher, when it is done, it tells you.

The completed battery shows 13.09 volts.

The battery was disconnected from the charger and left to rest for an hour to check the residual charge. The voltmeter showed a full 13.09 volts resting voltage, and the car has not had any issues starting for 1 week without any additional charging for our tests. After the one-week, the battery has been connected to the charger nightly.

The alternator in the car needs to be replaced, as it is only charging part of the time. This is where a smart charger is very handy. The battery can be connected each night to ensure that the battery stays charged until the alternator can be replaced. Many modern cars use alternator locations that make it extremely difficult to change them, and the car is often down for a long time. This particular vehicle, a 2000 Mercury Cougar, is one of those vehicles. Until the alternator can be replaced, the Pro-Logix Charger will keep the battery from being deeply discharged and ruined, and allow the owner to continue driving it to work. If you have a long commute, this is not a good solution, but if you only have to drive 30 miles a day, it is good stop-gap alternative.

You shouldn't get the iPhone 7 Smart Battery Case wet, but that didn't stop this developer from putting it to the test

The iPhone 7 is Apple’s first officially water resistant phone. We put this water resistance to the test on video in our recent post about the top iPhone 7 features. Some people have also wondered how cases might fare when subjected to water. A case like Apple’s iPhone 7 Silicone Case would be okay, but I certainly wouldn’t recommend submerging Apple’s iPhone 7 Leather Case.

What about the iPhone 7 Smart Battery Case? It features the same material used in the silicone case, yet includes a 2365 mAh battery sealed inside. Is it safe to get the Smart Battery Case wet? Apple’s official response to that question is a very unambiguous no. Yet, that didn’t stop AirParrot Remote developer, Squirrels, from testing the limits of the case’s potential water resistance while on a company retreat.

Apple’s official stance on getting the Smart Battery Case wet is clear, as it’s mentioned several times in the instructions that ship with the case:

  • Don’t open, remove, crush, puncture, or short circuit the Smart Battery Case, or expose it to fire, high temperatures, or liquids.
  • Don’t connect or disconnect the Smart Battery Case or a Power Adapter with wet hands.
  • Unplug the Smart Battery Case if any of the following conditions exist: The case of iPhone is damaged, exposed to rain, liquid, excessive moisture, or needs service or repair.

In addition, someone decided to ask Apple Support on Twitter about how the case interacts with water:

So yes, it’s very clear that you should, according to official Apple documentation, absolutely steer clear of water when charging your iPhone. Yet, due to the fact that the iPhone 7 is IP67-certified — meaning it can be submerged for up to 30 minutes in up to 1 meter of static water — it might be tempting to put peripherals, like the Smart Battery Case, to the test.

But you really shouldn’t do this. Apple’s documentation makes it abundantly clear that you shouldn’t get the Smart Battery Case wet, and that you definitely shouldn’t charge your iPhone while it is wet, even if it’s being charged by the Smart Battery Case, and not the typical AC outlet. Electricity and water, right?

We review the iPhone 7 Smart Battery Case + subscribe to our YouTube channel

Still, curiosity can make it easy to disregard even the clearest of warnings, which is why the development team at Squirrels decided to put the iPhone 7 Smart Battery Case to the test. (To be clear, Squirrels is not endorsing such activity, but wanted to share their findings with me, as they knew I’d be interested in the results.)

The Squirrels team submerged the new iPhone 7 Smart Battery case in:

  • a pool at 2-feet deep for 30 minutes
  • Florida Gulf Coast saltwater at 1-foot deep for an hour
  • a hot tub at 1-foot for 30 minutes

Needless to say, that’s a pretty extreme series of tests, but the Smart Battery Case came out relatively unscathed. It’s also worth noting that this test is making me long for another beach vacation ⛱.

Apple’s iPhone 7 Smart Battery Case is epoxy-sealed, which helps keep the inside dry

Squirrels does warn that cheaper Lightning cables are subject to corrosion when wet, while Apple’s own Lightning connector didn’t encounter any issues with corrosion. In other words, you’ll want to make sure that the case is completely dry before attempting to charge again, especially if using third-party cables.

It held up well, but it’s still not a good idea to get the Smart Battery Case wet

Further, Squirrels discovered that the case’s internal components are epoxy sealed, which help provide liquid ingress protection. When considering the case’s build materials, it’s not totally surprising that it held up well under these conditions. In fact, many found that the iPhone 6s could stand up to water much better than expected, even though Apple wouldn’t acknowledge any level of water resistance.

What can we learn from this test?

Despite how well the case fared, it’s still not a smart idea to get your iPhone 7 Smart Battery case wet to any degree, and you’ll definitely want to avoid charging the case or your iPhone until it’s dry if it happens to get wet.

But it’s nice to see that if you do have an accident that causes the case to get wet, it’s not necessarily the end of the world for the $99 accessory. Simply allow it adequate time to completely dry before trying to use it again.

Smart Batteries¶

  Copter

ArduPilot supports two types of “smart batteries” that communicate using SMBus, the Maxell battery and the Solo battery. While not yet very common, smart batteries are easier to attach and detach from the vehicle and are capable of providing more information on the state of the battery including capacity and individual cell voltages (not yet supported).

Note

Support for Solo smart batteries was introduced in Copter-3.3, Maxell battery support arrived in Copter-3.5. We have not yet found a webstore that sells the Maxell smart batteries.

The diagram above shows how to connect the Maxell battery to a Pixhawk.

SMBus is close enough to I2C that the GND, SDA and SCLK lines from the battery can be connected to the Pixhawk’s I2C connector (see I2C pin assignment on this page).

If using the Maxell battery set BATT_MONITOR to “7” (“SMBus-Maxell”).

If using the Solo battery set BATT_MONITOR to “5” (which may appear as “SMBus” or “Solo” depending upon the software version).

Restart the board and connect with a ground station and check the battery voltage appears. If using the solo battery, the BATT_CAPACITY parameter should be automatically updated to the batteries actual capacity in mAh.

  • Battery “address discovery” is not supported so the battery must use the I2C address 0x0B (7 bit address). Most smart batteries use this address.

  • If using a Solo battery with Copter-3.4.6 (or earlier) with a Pixhawk1, the ArduPilot start-up scripts must be modified to search for the battery on the “external” I2C bus. This is not necessary if using Copter-3.5 (or higher) This can be changed in the startup scripts (see line below) to tell the batt_smbus driver to searching on bus “1” instead of “2”:

    # optional smbus battery monitor if batt_smbus -b 2 start
