How understand when the battery is 100%?

From the outside battery light , how can i understand when the battery is 100% charged?? is the first time i use it, and so is the first charging now the light is white, stable, not flashing! I never start the lenovo so i don't know how much was the battery %!
Therefore, how much do you think i should let it charging for the first time??
Thanks

welcome! I have had my mac for 2 years and it has only 77 cycles on it and still has a fantastic charge, I leave it plugged in almost all the time. Read this also: http://www.apple.com/batteries/notebooks.html

I just got my MBP 6 days ago. When the battery is 100%, it says that the remaining time is only about 5 hours. Isn't it supposed to be higher?

I'm just wondering if my computer is defective? The battery life should be 9 hours, and it's not like I have a thousand apps open or anything.

Not quite. Please read the 'fine print', the operative words being 'up to'. Then if you read the criteria used to achieve that level you will find the the least CPU/GPU intensive application was used with nothing else open.
Furthermore, that time estimate is not very reliable since it reflects what is occurring at that given moment. That can be very volatile and can be observed by opening and watching Activity Monitor. I suggest you use the % option.

HT4623 Hi!My iPAD lost its charge fast !!I've got an iPAD capacity 57,1GB and it has available 55,1GB ,version 7.0.4 .I'd like to know how long does the battery last when it is 100 % charged.

Hi!I've just installed the iOS 7.0.4 operating system and the battery lost its charge at an incredibly speed.I'd like to know how long does the battery last if everything is right when it has 100% charge.Thanks!

I`m `propping` up this thread to to the top of the forums again as it`s been three months and not a single community member or Apple support personnel have replied, which I find discouraging.
I`ve tried everything - both the iOS device(s) and Apple TV have been upgraded (albeit reluctantly) to the latest versions, since iOS 7 looks like crap compared to iOS 6. Both use the same WiFi network. Bluetooth is set to `off`, as per the online tutorials on the Apple Support page.
I also tried shutting all of them down, including the router, waiting 30 seconds and turning the router, then the Apple TV then the iOS device on sequentially with 30 seconds in between each, again as per this discussion forum, and still nothing.
Why can Apple not make a technology, such as AirPlay, work with greater than 10%?
Any other ideas?
Come on, people.
Thanks,
Doug

You're on your own. Good luck.

Should I disconnect the charger once the battery is 100% full. Or can I use the laptop plugged even when the battery is full., Should I disconnect the charger once the battery is 100% full. Or can I use the laptop plugged even when the battery is full.

You can leave the charger plugged in, as you cannot overcharge...charging automatically stops when your battery is full. Once every 2 ~ 3 months, its a good idea to drain the battery to about ~ 40%, then recharge to full. Otherwise, you can charge whenever you like & leave connected whenever you like.
Try to avoid full battery discharges, Lithium batteries don't like that & frequent full discharge/recharge cycles will eventually kill your battery.

Why i can't see the "full charged logo" when iphone battery full 100% in ios7.0.2

Try this:
Go into Power Manager, choose the Logging profile.
Go into Windows' Power Options, choose a different profile, then switch back to the Logging profile.
See if this clears any contradiction between the two.

I use my 7th gen ipod on bluetooth and when the battery dies while on bluetooth it wont turn on or charge and the computer doesnt find it. This is my 2nd nano in just over a month. The first one had the same problem. how can i fix this?

I have the latest ipod nano (7th gen, 16gb) and I use it mostly on bluetooth. When the battery dies during use with the Bluetooth it doesn't take a charge, the battery doesn't turn on and of course the computer doesn't even acknowledge that it's plugged in. This is my second nano in just over a month, the same thing happen with the first one. I just want to know if their is a way to fix this so I don't have to keep sending it in? Or maybe pay the difference to upgrade to a touch?

If the battery has been completely depleted on the Nano (not really a good idea) then it is going to take 15 to 30 minutes before your computer can see it. Same thing will happen with an iPod Touch.

How can you tell when the battery is fully charged?

when done syncing, i have a totally green large battery icon- but thats what i always have- any other indication- or am i misreading the large green battery as an indicator to charge completness?
the little white battery icon never seems to change when using touch 2g?
what am i missing please
thank you very much

The small battery symbol has a lightning bolt symbol when the battery is charging and a electrical plug symbol when it is completely charged.

When the battery charged fully in macbook pro and the charger (AC Adapter)

when the battery charged fully in macbook pro and the charger (AC Adapter) is connecting (Showing Green Lamp) to the macbook pro does that effect to the battery live of the macbook pro with Retina Display 15'' ME665
Also I want know the Best headphone compatible with macbook pro Retina that help me to Hear and Record ?
Notes ( the macbook pro 15" has just one port for the headphone usually it's tow for record and hear)
Best Regards,

The MacBook Pro charging circuit will charge the battery until it reaches 100% charge and then switch to power mode for the MBP. When the battery drops to 93-95% charge the circuit will switch back to charging mode to top off the battery charge again. You will not harm the battery or MBP by leaving it plugged in most of the time.
There are many good headphone/microphone combinations on the market, best really is more a function of how much money you want to spend. Check those offered in the Apple on-line store for features/price to see what would best fit your needs. You can also look at audio equipment suppliers, all the earphones need is a standard 3.5 mm plug.

Can I use my iPad Mini while plugged in thus keeping the battery at 100%?

Can I use my iPad Mini while plugged in thus keeping the battery at 100%?
Or must I use it on battery all the time?

Copied from Texas Mac Man ...
The quickest way (and really the only way) to charge your iPad is with the included 10W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
How to Calibrate Your Mac, iPhone, or iPad Battery
http://www.macblend.com/how-to-calibrate-your-mac-iphone-or-ipad-battery/
At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

My phone seems to delete contacts and info when the battery gets low, is there a solution to this issue?!

After the most recent update, I've noticed a couple MAJOR changes! 1) The battery life can barely make it through half the day. I have to keep charging it no matter how little I use it. I've even turned off apps running in the background, it didn't make much difference. And 2) When the battery gets really low, at the 10% mark, it deletes contacts and settings. I've lost so many contacts all of the sudden and I constantly have to restore my iPhone. It's so frustrating! And when the battery gets low, it also deletes my e-mail account to receive e-mails on the phone. I'm tired of having to constantly reset my phone carry a charger with me, it's not reliable any longer and I'm not sure why. Help??

Here is some information on the applecare +:
http://www.apple.com/support/products/iphone.html
It appears that you have to buy the applecare within 30 days of buying your phone - you said that your phone warranty is almost over, so when did you buy it??? That could be the explanation for the error.

ZBook 17 powers on automatically when the battery is removed and placed back

Hi all,
I am an IT engineer with a 15 years hands on experience and troubleshooting skills.
2 of the laptops I own are ZBook 17.
One is a UK import (F0V53ET, manufactured in October 2013) and the other is a US import (D5D93AV, manufactured in April 2014). Both of them are running the latest BIOS revision (v01.21).
The strange problem I encountered is as follows:
At the D5D93AV when the AC and the battery are removed (i.e. for upgrading the RAM), when the battery is placed back in, the system automatically powers on. Same applies if there is NO battery attached and the AC plug is attached.
At the F0V53ET, this does not happen (and the normal is NOT to happen).
What I tried to do so far to see if the problem is resolved at the D5D93AV:
1) I upgraded the BIOS to the latest version (v01.21) at both the ZBooks.
2) Ensured that BOTH the laptops have exactly identical BIOS settings.
3) Ensured that turn on the machine while on AC is UNCHECKED.
4) Ensured that there are no power on options enabled (like the timed power on, e.t.c.)
5) Tried to disable settings like "USB charge, wake on USB" e.t.c.
6) Tried to remove the CMOS battery, press the power button with no battery or AC to fully discharge, attach the CMOS battery after a minute to ensure the CMOS was cleared and placed everything back.
7) Tried to replace the OS from Windows 8.1 Pro to Windows 7 Pro to see if it has an impact to the UEFI Bios settings (i.e. any conflict with Hybrid sleep e.t.c.).
8) Tried to enable "Power on while on AC" to see if the system behavior changes. When the battery is attached and the AC is also attached, it will power on if the "Power on while on AC" is enabled (so this works as expected).
9) The problem gets reproduced ONLY when there is either no battery and the AC is attached, or when the battery is attached without the AC (i.e. after reassembling the machine after a RAM upgrade). Then it powers on automatically.
10) I also swapped the batteries between the 2 ZBooks but the issue with the US model is not resolved either. The battery works fine.
It seems to be either a BIOS issue, or a Power Board issue (hardware fault). The UK model behaves as expected, while the US model seems to have these issues.
Any ideas will be really useful.
So far this is what I did not try yet (due to lack of time):
11) To attach the US model to a docking station and see how it behaves.
12) To disable or enable the Hybrid sleep from the Bios (instead of leaving this to AUTO).
13) To replace the CMOS battery (swap them between the 2 Zbooks), although I don't think it might be the battery as the US unit is NEW with 12 hours of use.
14) To completely remove (or swap) the Optical drives and see if the problem still persists. I know there are some really rare occassions that the Optical drive might be partially faulty and short circuiting. It may sound crazy, but I have seen and experienced this more than 3 times espexially at desktop machines.
Any info or tips will be useful, although I am afraid I may have to escalate it to the 3rd line of HP as it is a really odd issue.

Hello, @panoulix
To get your issue more exposure I would suggest posting it in the commercial forums since the HP ZBook 17 Mobile Workstation is a commercial product. You can do this at Notebook - HP ProBook, ZBook, EliteBook, Compaq, Slate/Tablet PC, Armada, LTE.
The support page for your product may be helpful in the meantime:
HP ZBook 17 Mobile Workstation.
I hope this helps!
Thank you for posting on the HP Forums.
