Is the battery built-in or easily removed?

I just wanted to know whether the new macbook follows the design of the airbook
in this respect. I prefer to have more than one battery ready for use, is the need arise

The user manual is already available (don't recall the link though). The steps to remove the battery, replace the hard drive, or swap memory are pretty much the same action. It might even be easier. I believe it can be done without tools now. In previous generations, you had to at least have a coin or other device to turn the battery lock.

that seems normal: http://support.apple.com/kb/TS1909. Also, new macs do not require battery calibration: http://support.apple.com/kb/HT1490

Is it normal that after the battery says charged and i remove the cable, the percentage is 96% not 100% is that normal?, is it normal that after the battery says charged and i remove the cable, the percentage is 96% not 100% is that normal?

please help i just bought it

Let me repeat what Sig said in different words.
When you fully charge your battery, your MBP will say 100% and the light on the charger will turn from amber to green.
With the charger still connected, as you use your MBP, the charge level will decline from 100% to 95% and the light on the charger will be green. It is no longer charging the battery but is providing power to the MBP while you are using it.
When the charge level falls below 95%, the charger will the start charging the battery as well as providing power while you are using the MBP. The light on the charger will turn amber.
When it reaches 100%, then the cycle will repeat.
Also you might read this about your MBP battery:

None of my battery (built-in and removable) are charging and both to 0%

Dear all,
I have a Thinkpad T440s (Windows 7 /Ubuntu dual boot) for 1 year.
Everything went fine at the beginning with the battery. I then had several problems with the removable battery charging only to 63%. Now the problem is even more bothering because both batteries are at 0% but none of them is able to reload... So my computer only works with A/C...
I have the Lenovo power manager (from the beginning) telling me that battery 1 (built-in) is 0% and is charging (but it doesn't in fact..) and battery 2 is 0% and without activity.
I have tried thousands of tricks like reinstalling the power manager app, resetting the built-in battery (in the BIOS), play with the threshold or alimentation modes. I don't know what to do at the moment......
Please bring me some help, I'm desperate!
Thanks in advance
Kind regards,
David

Hi David,
Have you performed the above troubleshooting which was provided earlier?
If yes and the issue still persist, then it could be related to the hardware issue. You have to visit nearby Lenovo authorized service center for further assistance.

Updated to 4.4 and now my Bluetooth 'studders' when listening to music and a phone call. Yes I have reset the phone and removed the battery.

I just updated my Note 3 to 4.4.2. Since then when I listen to music or make a call on my Bluetooth my music and calls 'studders' and has some type of 'drop-outs' during the music and calls. This was not the case prior to the update.
Yes, I have power down the phone. Yes, I have removed the battery and restarted the phone. My Bluetooth headset is an LG 730. I tried listening to music on my other Bluetooth devices and they also 'studders' and has drop-outs during calls and music. I connected with a wired headset and the 'studdering' disappeared.
Is there a way to revert back to the previous 4.3 version of Android. I use my phone extensively for business and drive with it. The law for my state requires 'hands free' usage of my phone.

Unfortunately, I was forced to do a factory Reset. This wiped the device to a new state.
Afterwards all Blue-tooth, wi-fi and calls operated fine.
I would advise that you notify your customers that they would most likely have to do a Factory Reset once they update their device.
All contacts, pictures, data and applications were either lost or had to be reinstalled.

My MacBook Air 13' (2013) will occasionally start the fan at full blast, not connect to any wifi or detect any wifi, and will remove the battery icon from my menu bad as well as tell me there is no battery connected. How do I fix this?

My MacBook Air 13' (2013) will occasionally start the fan at full blast, not connect to any wifi or detect any wifi, and will remove the battery icon from my menu bad as well as tell me there is no battery connected. How do I fix this? I have restarted my computer multiple times, **** it down, and ran a diagnostic test to tell me nothing is wrong and my computer is not running any applications. There is no reason for the fan to be on full blast! when I try to set the option to show my battery icon in the menu bar, it will automatically uncheck. How do I fix all of this?

Have you tried SMC and PRAM resets?

I removed my battery in an attempt to insert a SIM card, obviously without knowing how to insert the SIM card. I put the battery back into place and it was already charged 100%, but it's stuck in recovery mode. I've already restored it, but it won't boot.

I was trying to insert a SIM card into my iPhone 4 without actually knowing how to do so. I assumed that I was to remove the back of the phone and find a slot for it near the battery. I removed the battery in an attempt to find a SIM slot, and was obviously unsuccessful. I put the battery back into place and screwed the phone back plate back on. Note: the battery was fully charged and the iPhone was working perfectly fine before. After screwing the iPhone back into place properly, I thought, I attempted to cut the phone on and it would not do so. I put it back on the charger, and the screen came up that says "Connect to iTunes". I obviously couldn't do so if its plugged into the wall. I plugged into the computer, connected it to iTunes, went through the Recovery mode process, and it still won't turn on. The computer says that the iPhone is in Recovery mode, but iTunes can't do anything because it has already been restored. When I disconnect it from the computer, I hold all buttons in all possible combinations, but it won't turn on at all. When I plug it into the wall, it again says to connect to iTunes. I don't know if I damaged the battery or any part within the iPhone, but I was sensitive in my approach to removing the battery and putting it back in, and there is no visible damage whatsoever. I am extremely frustrated and in desperate need of Apple-Pro help.

do you have a cdma iphone 4? becauase cdma iphones dont have a sim card slot... the providers that use cdma technology here in the us would be verizion, sprint, criket, ect... if you want to use your iphone 4 on att or tmobile (gsm carriers). then you would need a gsm iphone 4 (has sim card slot). a gsm iphone 4 is different than a cdma iphone 4 (they have different radio chips). maby you missed the sim card slot? sim card slot would be on the side of the phone.. never inside (unless it has a removable back cover like the galaxy s3 or s4), if you dont see a sim card slot on the side of the phone than you have a cmda iphone 4. can you tell me what carrier you are trying to use?

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.

How can I remove the battery from my Iphone and Ipads?

How can I remove the battery from my iphone and ipad?

The iPhone and iPad do not have user serviceable batteries. Battery replacement is handled by Apple. Make an appointment at the Genius Bar if battery replacement is required.

How can I remove the battery from my IPhone

my phone will not complete a call.

You should not remove the battery.
It is not meant to be removed by the consumer.
Have you tried a reset?
Restore?

Pls help me my ipod nano wont charge even if i use other laptop or pc . The battery notification tells its full charge but when i remove my ipod its still not charged

Is it not charging at all? Did you try to reset? If YES to both, request for a replacement of the ipod. Battery or the unit itself is defective. Cheers!

My macbook pro running lion will not boot . it stays on the grey page with the cog spinning. I have tried all methods of booting to no avail. I have removed the bottom and taken out the battery and the ram . will this affect my applecare warranty.

my macbook pro running lion will not boot . it stays on the grey page with the cog spinning. I have tried all methods of booting to no avail. I have removed the bottom and taken out the battery and the ram . will this affect my applecare warranty. I had to try myself as I'm overseas for two months and nowhere near any sort of help .

there was a recent software update that seemed to screw HDV up. Do some searching here over the last month or 2 and you'll find a bunch of posts and some possible solutions.
Worst case scenario, do as Shane suggests. But might I suggest you take a look at the user tips section of the forum. there are some great tips on how to prevent these sorts of problems by cloning your startup drive, etc.

Small electric shocks, laptop refused to start until I remove the battery and put it back in.

I own a Dell Inspiron 15 7000 Series i7537T-5005sLV.
A short while ago I tried to power on my laptop but it didn't come on. I thought that the battery drained and I didn't notice however when I plugged in the power cord no lights came on. I decided to open up the laptop and remove the battery and put back the battery and try to power on the laptop. It came on after doing that and I saw lights again.
I also notice that after reseating the battery, the latency between pressing the power button and the laptop actually coming on is shorter. It is almost instantaneous.Before there was about a 1.5 seconds delay. (THIS COULD BE MY IMAGINATION THOUGH)
I also noticed that I got little "pinches" or small shocks when my skin comes in contact with the edge of the laptop, especially at the end of the palm rest area. The shocking sensation could be cause the hair on my hands as my skin brush along the edges of the laptop as I type. I say this because I've never experienced a shock touching anywhere else on the laptop and I never felt a shock while using the tips of my fingers to touch the edges.
One last thing I feel I should mention. Around the SD card slot area there is a small dent protruding outwards; barely noticeable. It was a brand new laptop and the seal on the box wasn't broken or tampered with so I am assuming that this was a manufacture's defect. One I was willing to overlook since the dent wasn't that bad and added some character to the laptop. However I am beginning to worry that the unit might be damaged and that is why I had the power issue.
The laptop is about two weeks old. I had to replace the first one because the display had horizontal waves running from top to bottom. Even in the BIOS. They were especially visible against gray backgrounds.
I don't want to have to return another one and I like the laptop but if it is unsafe to use then I'd rather send it back and keep my life.

Hi Groudie,
I would suggest you to use the system in a work place or your friends place to check if issue reoccurs.

Very secure BB Curve 8320 - wipes itself if the battery dies or is removed

I seem to have purchased an interesting BB last year. If I let the battery die or even remove it from the BB I then lose everything and have to reload the OS and restore my last backup. This has become very painful as I have acquired some apps I like and I hate to keep reinstalling them.
T-Mobile BB Curve Titanium 8320
v4.5.0.81 (platform 2.7.0.78
This occurs even with a fresh install of the default apps.
Pulling the battery requires a new install of the OS
BT doesn't matter as this occurs even with a fresh install with nothing else having been done to the device but pull the battery or let it die.
doesn't matter if the SIM is in or not
doesn't matter if the microSD card is in or not
Replicate:
when the device is completely wiped and there is no OS, and the light flashes RED (5 times?)
reinstall the OS, accept the defaults
when completed then pull the battery
screen goes black
put battery back in
begin loop
screen remains black
LED flashes RED (5 times?)
screen remains black
return
end loop
rinse and repeat until you are tired of this game
anyone else have this issue or am I the only one with this advanced security feature?

I don't understand how this is any advanced security feature. Seems more like a problem.
I would recommend you upgrade the device to the latest 8320 OS release, the one you're using is quite out of date.
1. Do a complete backup of the device if you can, using Desktop Manager.
2. Wipe the device first (options > security > general settings > menu key > wipe handheld).
3. upgrade. See the instructions in the link below for download link and instructions.
