Battery charging and power adaptor issues

I'm having slight issues with both my power adaptor and the battery itself.
First I think I have cord issues as the light status can change from dim green to red or bright green if I move the cord around.
Second, my MBP is having trouble recognising if power is going to the battery or if it's charging etc. It can recognise if there's no adaptor connected at all, but if there's an adaptor connected, it has trouble seeing if there's power coming from the adaptor even if the light is on. I.e. it can stay at 100% and supply comes from the power adaptor and then suddenly drop to 80% power and start charging agan. One issue that happened earlier today was the adaptor was connected, and the battery indicator was at 100% with supply from the adaptor. Suddenly the MBP shutdown, and when I rebooted it was at 17% (I've tried repeating that in case of a dodgy battery but I couldn't)

If that doesn't help, the problem could be the adapter, the battery, or the I/O board (or a couple of less likely things). If you can borrow another adapter and/or battery, try them to see where the problem is. Or, if you're near an Apple Store, take it in and they'll diagnose it for you (for free, but they will charge for repairs if you need them and don't have AppleCare).

It rained in my window last night, on my power strip. My macbook adaptor (charger) and iphone adaptor were both plugged into the strip. The power strip is dead. Iphone is fine. Macbook will not boot up and charger light doesn't go on.

Spill Cleaning
And, don't think that just because it was two teaspoons and not a glassful that there is a difference.
Some liquid has just spilled into your Mac. What should you do?
Do
Immediately shut down the computer and unplug the power cord.
Remove the computer's battery (if you can)
Disconnect any peripherals (printers, iPods, scanners, cameras, etc.)
Lay the computer upside down on paper towels to get as much liquid as possible to drip out.
Note what was spilled on your Mac.
Bring the computer into an Apple store or AASP as soon as possible.
Don't
Don't try to turn it back on. Liquids can help electrical current move about the components of your Mac in destructive ways.
Don't shake the computer (this will only spread the liquid around).
Don't use a hair dryer on it (even at a low setting a hair dryer will damage sensitive components).
Do not put in a bag of rice in as much as rice will get into the ports and optical drive and do further damage.

This morning, my macbook pro won't turn on even though the battery is charged and power cord is working. it worked fine last night. what can i do?

Understanding iPhone Charging and Power Adapters

I've been in a protracted discussion (now locked) regarding iPhone battery charging and whether it is harmful/helpful to use the iPad power adapter rather than the iPhone power adapter.
There are a lot of misconceptions related to iPhone charging and current ratings on the iPhone and iPad power adapters. As an electrical engineer, I'd like to clear up some misconceptions.
Apple supplies a power adapter, not a "battery charger," with the iPhone and iPad.
The iPhone power adapter supplies a constant 5V at up to 1A (rated–independent tests have shown that it can supply almost 1.8A).
The iPad power adapter supplies a constant 5V at up to 2 or 2.1A (rated).
The iPhone's battery charging voltage and current are regulated within the phone.
The iPhone's battery is rated at 3.7V. Charged with the raw 5V from the power adapter, it would be destroyed. Fortunately, the internal regulation in the iPhone prevents that.
The maximum current that an iPhone will draw from a 5V power adapter is right around 1 amp. It does not matter if the charger is capable of supplying more, that's the most that the iPhone will use.
Because of the internal charge regulation, the iPhone battery will not charge any faster on an iPad power adapter than on an iPhone power adapter.
Apple approves the use of the iPad power adapter with the iPhone. It is completely safe for that purpose and does not harm the phone or battery in any way.
A water analogy might make this much easier for people without electrical engineering background to understand.
Water pressure (psi) is analogous to voltage.
Water flow (gallons per minute) is equivalent to current flow (amps).
A faucet valve is analogous to the iPhones battery charging regulation circuitry.
A bucket's capacity (gallons) is analogous to a battery's capacity (amp-hours or AH).
Let's say you adjust the faucet to flow 1/10 of a gallon per hour. The five gallon bucket will take 50 minutes to fill up. Easy enough. But then...
You need a lot more water flow for a new sprinkler system.
You need a lot more current for your new iPad.
Since the water pressure is constant at 80psi, the only way to get more flow use a bigger supply line.
Since the voltage is constant at 5V, the only way to get more current is to use a higher current power adapter.
After installing the new higher capacity water supply line, you go out to your faucet and adjust it to 1/10 of a gallon per hour.
After plugging in the higher capacity iPad adapter, you plug in your iPhone and its charging regulation circuitry adjusts the current flow to about an amp.
The bucket still takes just as long to fill up.
The battery still takes just as long to charge.
The faucet is not under additional strain since the pressure is still 80psi.
The iPhone's battery charging circuitry is not under additional strain since the supply voltage is still 5V.
I hope that I've clarified this for those who want to better understand the subject.

As far as the battery status, the tiny little icon in
the upper right corner of the screen is somewhat
helpful, but while it is connected it does not
actually indicate the level of the charge or that the
Iphone is charging. I was hoping to find a more
informative screen that would give better battery
details. When you first connect the iPhone sometimes
I get a large battery icon that shows the level
visually Is there a way to navigate to this screen?
1. Press the top button to turn the display off if it's not off already.
2. Connect to a power source.
3. The screen should display a large battery meter in the middle of the screen that actually shows the state of charge, even if charging.
If you don't see this plugged into your Mac try the AC adapter that came with the phone. If you still don't see it take it to an Apple store.

When I got a new iPhone5, I experienced short battery life, and system sofware issues were not the cause. The camera also takes a blury picture regardless of lighting and I have the black one. Has anyone else experienced similar problems?

What makes you so sure it isn't software?
The camera can be focused by take the point of focus on the touch screen.
If it is new as you said, it should be under warranty. Make a Genius Bar appointment or contact Apple with a repair request.

First battery charge and current issues?

Hi!
I just bought a new MacBook (2.0 GHz, 160 GB). I have two quick questions:
1. I plugged in my AC adapter, turned on the notebook for about 5 minutes to make sure it works fine, etc, then shut it down to let the battery charge. Would I have lost any battery capacity by not fully charging the battery first? And do I need to let the battery run through a full cycle when I first use the computer to ensure full capacity?
2. Are there any updates/best practices for the 2008 (December) MacBook batteries? I know there was an issue in 2007, but for the new line am I set to go? And is it still best practice to put shut the Mac down instead of putting it to sleep to save wear and tear on the hard-drive/battery?
sorry for all the questions: it has been 5 years since I bought my last notebook so I am a bit rusty/excited!

Battery Charging and Diagnostic Issue

My problems began a year ago when I bought a HP Envy 17. I'm sure you hear that a lot.
I have come to terms with carrying a portable fire hazard around with me, as with the bizarre decision to seemingly set a different temperature for 'auto-overheat emergency shutdown' off battery than when on battery (side-note, any cure for that?)
More pressingly, my battery has decided that it no longer wishes to charge itself. It has slowly reduced from 100% to 0% over the past few days, even when plugged in. The mesage reads "plugged in, not charging"
The suggestion from HP forums is to follow the instructions here:
http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&dlc=en&docname=c01443470
I resolved to perform a battery test. It took several attempts to reach system diagnostics, but the battery test option was easy to find. On being asked to perform it, the screen displayed the following:
Battery Check - Test in Progress
Estimated Remaining Time: 8 seconds
Progress: 0%
It remained the same for the next 10 minutes. There was no response either to any attempt to exit the check by using the ESCape key. Eventually, I performed a sophisticated manouevre which involved pressing the 'Off' key, then trying again. The same happened the next time.
Am I not waiting long enough? Or is there a better way to deal with the issue? Any advice would be appreciated. Thanks in advance.
EDIT: Resolved by reference to a response given to a user who posted half an hour after I did. Bit sad I didn't receive one. Any info on how to meddle with the auto-shutdown thing would still be appreciated.

Hi E57,
Thank you for your inquiry.
I am glad you were able to resolve your issue from another thread.
I do not know how to meddle with the autoshut down fearture, but here is a document that may assist you to reduce the overheating issues. Troubleshooting an Overheating and Auto Shutdown Issue.

Firewire, can I use it to charge with power adaptor?

Ok so I have the new 30GB iPod Video, and I only have USB1.1 ports, yes it *****, yes it'll take all night for me to load all my songs on it. Well what can you do!
My Question is can I use firewire with a power adaptor to charge it away from my computer or do I need to buy a USB power adaptor?
Any advice would be most appreciated
John

Yes, you can use the firewire power adapter to charge the iPod.

How can I resolve iPod Touch 4th gen charging and iTunes connection issue?

I have an iPod Touch 4th generation and the other day it stopped charging. When I pug it in, it appears to be receiving a minimal charge to keep it alive, but isn't restoring the battery life and doesn't show that the battery is accepting the charge. After plugging it in for a day, the battery was only partially charged to approximately 20%. I've tried several USB cables and different plug-ins to no avail.
Then I tried to connect it to the computer and iTunes doesn't recognize it. I've tried uninstalling and reinstalling the Apple Device Manager and iTunes software, and resetting the iPod. I've also tried holding the sleep and home buttons at the same time while connecting the iPod to the computer with iTunes software open. Nothing seems to work. I have other iPods/iPhones that connect to iTunes without issue, so it is isolated event with this iPod Touch. I was hoping to restore the iPod to its original settings to see if that would do the trick, but am unable to figure out how without iTunes. Any suggestions? help!

Not Charge
- See:
iPod touch: Hardware troubleshooting
- Try another cable. Some 5G iPods were shipped with Lightning cable that were either initially defective or failed after short use.
- Try another charging source
- Inspect the dock connector on the iPod for bent or missing contacts, foreign material, corroded contacts, broken, missing or cracked plastic.
- Make an appointment at the Genus Bar of an Apple store.
Apple Retail Store - Genius Bar
and/or
Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

My Macbook Pro runs VERY slow when unplugged. The battery charges and runs ok. Ran an SMC reset (no success), Safe mode (did not work), and hardware check (came back ok). What can I try next to fix this?

Hello all,
I am new to posting on this forum but I really hope that someone out there can help me out. I have a 13" MacBook Pro, 2.53 GHz Core 2 Duo, 4GB 1067 MHz DDR3, running OSX 10.6.8. My problem is that when I unplug the laptop form the charger and run it on the battery, the computer becomes unresponsive to any commands at all. It basically really slows down to a crawl. Even when rebooting it will take 5-10 minutes or more to do so. The odd thing is, when it gets plugged back in while any of this is going on, within a minute or two it works perfectly. It has been in a mac authorized repair shop for 7 weeks and has had a new logic board and a new hard drive replaced. The battery was tested and charges fine, holds a charge when unplugged, and the system profile shows the battery at Normal. Recently, many knowledgeable mac enthusiasts gave me tip that might help. Here is what I did: Ran an SMC reboot (no success), rebooted the computer under safe mode then unplugged it to test (no success), and ran a hardware test on the install disk (showed hardware ok)
I am at a loss as to what to do next. It has become impossible to use this laptop for my classes when it is unplugged. I am about ready to just go buy a new one, and call this one a goner.
I am hoping someone reading this can help with any other ideas on its problem. Help? Anyone?
Steve

LPBassman,
since the tech in your IT department was able to copy your daughter’s data from her MacBook Pro’s internal disk, I’d suggest completely erasing the internal disk (using Disk Utility in Recovery mode, reformatting it with a “Mac OS Extended (Journaled)” filesystem), reïnstalling its original version of Mac OS X (either Snow Leopard from the grey Mac OS X Install DVD if it originally came with two grey DVDs, or Lion via OS X Internet Recovery if no grey DVDs originally came with it), running Software Update to get it to 10.6.8 or 10.7.5 respectively, reïnstalling Mavericks, running Software Update again to get it up to date, and finally restoring your daughter’s data.

Network Card turned off and Power regression issues.

Hello,
Can any one please help me setup wifi/ethernet on my Thinkpad t420? It has Intel Wifi Link 1000 BGN. If i am not wrong it is suppose to work by default. How and what modules do i have to load to turn on my wifi card? I know how to make wpa_supplicant work.
Their are power regression issues with linux kernel. How can i make pacman to not to upgrade to latest kernel releases?
Thanks.
PS:- I have done research but couldn't come find an answer. Sorry if this question has been asked many times.

Check http://intellinuxwireless.org/?n=Downloads for intel wifi drivers
Pacman should not syncronize system wide missing packages unless specified with the -u [OPTION] on the -S [SYNC] argument, see the man pages on pacman.

Also make sure you have done all the stuff on wireless setup in the beginner guide, it is very comprehensive

I need the mother board plug for the battery charger and Bios Battery for an XT178 Laptop?

HP xt178 Laptop (1P) F4685H SN: TW24604214
I need to replace the motherboard plug that the Battery Charger plugs into as it is broken.
The Bios Battery has failed and is NO: ML1220 with a number 28 in ink stamped on it.
are these parts available from HP or can you provide me with common part numbers.
Jack

Hey JD,
That's a reaalllllllllyyy old laptop. As an HP employee I feel obligated to recommend picking up a new one at your local retailer.
If you are serious about finding parts then you may be out of luck. HP stopped servicing that notebook in 2006.

Win 10 Upgrade and Power Manangement Issues

I have an S230u Twist. After upgrading to Win 10 I have the following outstanding issues: The most problematic is that after the upgrade I have an issue with the unit going to sleep. Upon waking, the screen brightness resets to about 5%. It doesn't do this all the time but often enough be irritating. I've turned off adaptive brightness but this doesn't help. I've run System File Checker which made some fixes to corrupt files and this helped somewhat. Lenovo Solutions Center reports that the Power Management Software is not installed even though I 've upgraded the Power Management driver with the Win 10 version. I'm at a loss to know what to check next to fix this. The other issue concers the start menu - the "Most Used" doesn't seem to update with the Most Used programs I use (most which are on the Task Bar). Any support I can get on the Power Management issue would be most appreciated.

I spent more hours trying to resolve. Down loaded driver 355.60 Win 10 64 bit (355.60-notebook-win10-64bit-international-whql)Uninstalled current driver and software via device manager.Expanded the driver and ran setup. Performed a custom install without GF Experience. Install went through fine and rebooted after removing software.Came back up and continued install and completed with no errors. Ran device driver and confirmed driver installed. Set GoogleEarth to run with graphics processor.Everything seemed okay.Set desktop to include in notification tray and Display GPU Activity so I could see that GE was running in processorThen launched GE with 3 buidings and citties. Ran site seeing tour.Crashed after a couple of minutes with System_thread_exception_not_handled and rebooted. When it came back up I turned of to show in notification tray and turned off GPU activity.Re-Ran GE and it lasted a bit longer and then crashed with the same errorSystem_thread_exception_not_handled and rebooted. Would welcome any further help.

Quick battery charge and drain

Hi,
I hope somebody will be able to help / explain this issue to me - I bought the z3c two days ago (haven't charged it for 30 min before first use, really don't know if this could be an issue), and I have noticed that unlike most people's charging time (which is about 2.5-3 hours) mine is around 1.5 hours on the micro usb charger (1% per 1 minute), and the battery drains quickly with a bit heavier usage. I upgraded it automatically to lollipop, and I did a factory reset afterwards when I noticed that the battery was draining quickly. Google location services have been disabled, I only keep the auto sync on from time to time.
Is there a possibility that something is wrong with the battery or am I just doing something wrong with the applications etc? Should I wait a couple of days to see how the battery behaves? (I'm sorry if this question has been repeated somewhere else already).

Hi Nerie
Welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.
You have taken some good steps so far to troubleshoot the problem. Have you tried putting the phone on Stamina mode and/or Low battery mode? These functions are designed to maximise the battery life. As well as turning off Google location services you can also turn off Bluetooth, Wi-Fi & Mobile data when not using them. Also try turning the screen brightness down as I can see the Screen is using the most power. Turn off phone or put into Airplane mode when there is no network coverage in the area as the phone repeatedly scans for available networks - which consumes power.
Hope the above steps do help, keep us updated.
