Battery charging & CPU heating issue

i've change week ago late 08 White MB 2.4GHz to Unibody 2GHz and notise following:
1. charging time increse in average in 2 times (from 2hrs to ~4hrs) and last 1,5 hrs avrg takes progress from 90% to 100%.
i found it very strange becouse unibody batt less on 1000 mA/rhs than batt in WhiteBook. Charger power supply in the same time not changed
what reason of so longe charging? is it normal or the bug? in travel conditions this "downgrade" is very noticeble
2. In "office mode" (web, mail, documents etc, with 15-20% CPU loading) avrg temp of my CPU by iStat is about 67/55C in AC/Batt mode. When I on AC some times it very uncomfortable for palms, especially for left
Is it "normal" or something wrong with my MB?

I can't help you with the battery... mine charges quite quickly. The old macbooks would overheat quite often, and the fans don't do anything to help. It will still work, but there's not much you can do. They seem to have fixed that for the aluminum MBs, but I don't know about the white one...

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.
I hope this has helped.

Probook 6550b Battery/Charging/AC Adapter Issues

Hi, I am having some trouble with my Probook 6550b and am pretty stumped and just want to inquire to the online community before I confirm my worst fear that I have a problem on the motherboard. I am running Windows 7 Professional 32 bit. I bought this laptop about a month ago second hand and it needed a new battery right off the bat and I knew this going in to the purchase. The laptop would still power on with the AC adapter though and the system seemed to run great other than the battery issue. I purchased a OEM replacement battery and installed the battery on arrival and I booted the computer up and everything looked to be working just like it should, the battery was charging and the icon was there in my tray as proof. I thought I had found the remedy to my situation but I was wrong. The battery had charged to about 50% when I shut the system down and I did not touch it for about 5 days until I came back from a family vacation and when I powered it back up the battery had 50% life left but it was no longer showing as charging in the system tray, yet the AC adapter was plugged in. The icon that I was seeing was a battery level without the plug next to it. I started to reasearch this issue and found many topics online about uninstalling battery drivers in device manager and followed that process quite a few times with no success. The battery was still not charging. I ran the HP battery check utility and everything came back perfect which led me to believe the battery was perfectly fine. A message appeared at the bottom of that window that told me there was no power supply hooked up (even though the adapted is still plugged in). I ended up running the battery all the way down to 5% during the research and experimentation process and now the laptop will not power on when both the battery and the AC adapted are connected. The battery itself will not power the computer back on (I am assuming since there is <5% life left), but it will power on with the AC adapter connected (but the battery cannot be installed). The system tray icon I am receiving is a low battery with a flashing 'X'. I have searched and searched online and have not really been able to come across any other possibilities other than a bad power supply or a bad charging mechanism on the motherboard. Some questions I have: Would a fresh installation of Windows possibly remedy this? (I figure not since the laptop will not start up with both battery and AC plugged in; screams hardware issue to me)Any BIOS settings that I may be overlooking?Could a BIOS update help?Any other Windows settings that I may check?If indeed this is a motherboard issue, where could I find a replacement?Thanks so much ahead of time for any and all responses, hopefully somebody will be able to help me!

EDIT: I install the battery after I startup the laptop with just the AC adapter and that's when I lose the power from the supply and the battery icon shows loe battery with a flashing red X. So basically when the battery is plugged in the computer disregards the power supply totally.

Battery draining/over heating issues - 925

hi all,
ive had this issue for a while now but havnt moaned about it until now but ive just had enough of this constant issue and want some help
i have the lumia 925 and have the above simptons, i have the lumia amber update and have disabled every setting and background app the only thing i have enabled and running in the backround are -
touch display is turned on (double tap to wake)
on my home screen i have the apps - Photos, Battery, Bing news, The Weather Chanel, set as live tiles
the backround apps i have running are - Battery, Bing News, Facebook and whatsapp
apart from that all other settings are disabled or off
i can disable bing news if have to but i dont think this is the issue here as before i was having the exact problem
one time i noticed a 30% decrease in battery, not to mention the battery got really hot in hand

Hey Robert,
If it's anything like my 920, sometimes it gets caught in a CRAZY battery drain cycle. Sometimes it may get hot, sometimes not, but I always make sure that my GPS is working correctly. A lot of times it's not, and I need to reset the phone by either turning it off or holding down the power and volume down buttons.
Especially check any apps that you may have downloaded that may be using GPS. Also, if you do the power + volume down, always turn your phone off again the normal slide down way afterwards or your live tiles won't update correctly.

MacBook Pro - Battery and Trackpad Heat Issue

Hi,
I purchased my MBPro 15-inch in December of 08 (so unibody type). For the last few months, after a couple of hours, the trackpad becomes unusable. You can't "click" and navigating around the screen clicks and unclicks and is general extremely sensitive.
When I remove the battery, it works fine (but you have to keep the power supply connected or it dies instantly). As of this week, when I replace the battery, it goes straight back to the problem. Previously, I would get 15-30 minutes of "normal" usage and then the problem would reassert itself.
Should I just get a new battery? Is this the kind of issue that Apple had previously on non-unibody MBPros and required a mass recall and replace of batteries?
Any suggestions would be greatly appreciated

Welcome to Apple Discussions!
This is likely the same issue which resulted in a recall of swollen batteries (Battery Update). Have you carefully checked your battery for any signs of swelling or leaking? If you do have a swollen battery, stop using it immediately and get a replacement. You don't want to risk permanent damage to your Mac.
The battery doesn't even have to be in use. Some time ago, someone posted a picture of a spare battery that had never been in a machine, but which had still swelled up and come apart.
There seems to be some question as to whether this is to be expected of all these batteries, or if it is an indication of a factory defect. For this reason, people have had mixed results trying to get the battery replaced for free from Apple. Generally, if you've been able to get 300 cycles out of your battery, your battery is just considered worn out and your chances of a free replacement are remote. If this happens on a newer battery with fewer cycles, I believe decisions are made on a case by case basis.
I actually hope that swelling is a characteristic of a defective battery and not something expected to happen to all of them. Especially since the new Unibody Macs now have a built-in battery that is not supposed to be user replaceable.
Good luck!

5s battery & heating issue (ios 8.1.3)!!!!!!!

i just bought 5s and updated it to ios 8.1.3, my maximum battery life is 4 and half hours of continues usage (just downloading apps and browsing and chat and no games), is that normal??

Hi Bebars100,
The resource below will provide information and tips to maximize the battery performance of your iPhone. If you follow these suggestions and still have issues with your new iPhone, it may require service.
Apple - Batteries - Maximizing Performance
https://www.apple.com/batteries/maximizing-performance/
“Battery life” is the amount of time your device runs before it needs to be recharged. “Battery lifespan” is the amount of time your battery lasts until it needs to be replaced. Maximize both and you’ll get the most out of your Apple devices
Your device is designed to perform well in a wide range of temperatures, with 62° to
72° F (16° to 22° C) as the ideal comfort zone. It’s especially important to avoid exposing your device to temperatures higher than 95° F (35° C), which can permanently damage battery capacity. That is, your battery won’t power your device as long on a given charge. Charging the device in high temperatures can damage it further. Even storing a battery in a hot environment can damage it irreversibly. When using your device in a very cold environment, you may notice a decrease in battery life, but this condition is temporary. Once the battery’s temperature returns to its normal operating range, its performance will return to normal as well.
iPhone, iPad, and iPod work best at 32° to 95° F (0° to 35° C). Storage temperature: -4° to 113° F (-20° to 45° C).
MacBook works best at 50° to 95° F (10° to 35° C). Storage temperature: -4° to 113° F (-20° to 45° C).
Charging your device when it’s inside certain styles of cases may generate excess heat, which can affect battery capacity. If you notice that your device gets hot when you charge it, take it out of its case first.
If you want to store your device long term, two key factors will affect the overall health of your battery: the environmental temperature and the percentage of charge on the battery when it’s powered down for storage. Therefore, we recommend the following:
Do not fully charge or fully discharge your device’s battery — charge it to around 50%. If you store a device when its battery is fully discharged, the battery could fall into a deep discharge state, which renders it incapable of holding a charge. Conversely, if you store it fully charged for an extended period of time, the battery may lose some capacity, leading to shorter battery life.
Power down the device to avoid additional battery use.
Place your device in a cool, moisture-free environment that’s less than 90° F (32° C).
If you plan to store your device for longer than six months, charge it to 50% every six months.
Depending on how long you store your device, it may be in a low-battery state when you remove it from long-term storage. After it’s removed from storage, it may require 20 minutes of charging with the original adapter before you can use it.
There are two simple ways you can preserve battery life — no matter how you use your device: adjust your screen brightness and use Wi-Fi.
Dim the screen or turn on Auto-Brightness to extend battery life.
To dim, swipe up from the bottom of any screen to open Control Center and drag the Brightness slider to the left.
Auto-Brightness adjusts your screen to lighting conditions automatically. To activate it, go to Settings > Display & Brightness and set Auto-Brightness to On.
When you use your device to access data, a Wi-Fi connection uses less power than a cellular network — so keep Wi-Fi on at all times. There are two ways to turn on Wi-Fi:
Swipe up to open Control Center, tap the Wi-Fi icon, and log in to a Wi-Fi network.
Go to Settings > Wi-Fi to access a Wi-Fi network.
iOS 8 is designed to be the most battery-efficient iOS ever. And it gives you more precise ways to manage your device’s battery life, because you can see the proportion of your battery used by each app (unless the device is charging). To view your usage, go to Settings > General > Usage > Battery Usage.
Here are the messages you may see listed below the apps you’ve been using:
Background Activity. This indicates that the battery was used by the app while it was in the background — that is, while you were using another app
To improve battery life, you can turn off the feature that allows apps to refresh in the background. Go to Settings > General > Background App Refresh and set the switch to Off.
If the Mail app lists Background Activity, you can choose to fetch data manually or increase the fetch interval. Go to Settings > Mail, Contacts, Calendars > Fetch New Data.
Location and Background Location. This indicates that the app is using location services.
You can optimize your battery life by turning off Location Services for the app. Turn off in Settings > Privacy > Location Services.
In Location Services, you can see each app listed with its permission setting. Apps that recently used location services have an indicator next to the on/off switch.
Home & Lock Screen. This indicates that the Home screen or Lock screen was displayed on your device. For example, the display was awakened by pressing the Home button or by a notification.
If an app frequently wakes your display with notifications, you can turn off push notifications for the app in Settings > Notifications. Tap App and set Allow Notifications to Off.

X230 CPU performance issue on AC power without battery

Dear Lenovo & Community Members,
I've recently received my X230 (model no.: 2320-24B), and discovered an issue related to the CPU performance of X230 on AC power. To make the long story short, my X230 is not running at full performance on AC power with battery detached. Accordingly, the X230 was shipped with setting at "Maximum Performance" under "Intel Speed Step" in BIOS by default on AC power.
Full Story:
My notebook is X230 (model 2320-24B) which comes with Ivy Bridge i7-3520M. I have a habit to detach the battery when it was fully charged, as I want to reduce the battery aging and my job does not always require me to work on the go. And by accident, I've discovered that X230 performs differently on AC power with and without battery. To be more precise, when my X230 runs on AC power with battery detached, it runs as slow as my Sandy Bridge i3-2100 desktop, which sounds very weird to me for a notebook costing me more than $1000.
Accordingly, I've benchmarked my X230 and here are the results, both with BIOS setting to "Maximum Performance" under AC Power:
AC power, without battery - WEI CPU Score: 4.9, WinRAR 4.2 benchmark: ~1,900kb/s, CPU @ 1.189Ghz on load
AC power, with battery - WEI CPU Score: 7.2, WinRAR 4.2 benchmark: ~4,000kb/s, CPU @ 3.6GHz on load
On battery power - WEI CPU: 7.2, WinRAR 4.2 benchmark: ~4,000kb/s, CPU @ 3.6GHz on load
Based on my tests, I’ve found that X230 is only performing at maximum performance when attached with its battery, and it is underperforming at its lowest clock speed when not being attached with the battery.
Conclusion:
I would like to ask if other owners of X230 in this community have the same problem (and are able to repeat my findings). I'm quite disappointed to find that my X230 is running even slower than my i3-2100 desktop, and it simply doesn't make sense for a notebook with removable battery yet unable to run at full performance without battery. I demand Lenovo to address this issue.
- Joseph (PhD Information Systems)
Edit: I'm already running the latest BIOS 1.12
Solved!
Go to Solution.

Hi slkong, welcome to the forum,
allow me to assume that you have the 65W AC power supply. If this is the case in order to reach full CPU performance you do need to have the battery attached, there are several threads on this within the boards concerning different systems and also this Knowledgebase article.
Hope this explains the situation for you.

IPAD 3 battery charging issues

iPAD 3 battery charging issues. Read most of the discussions. My question is: If I take my iPAD to Apple Genius bar - what's the test they do to qualify for a replacement (do they place it on a charge and see the charge for Y% for X minutes or do they have other methods)

We're iPad users like you, so don't know.
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.

Ipod 3rd Gen battery charge issue

I have various 3rd gen ipod's and logic boards. parts n pieces etc. here is my issue.... i recently purchased a new battery for 1 of these 3rd gen ipods to repair. when i first plugged everything in and connected usb cable ipod fired up no problems but the battery was not showing any charge. i even tested battery as it was charging with a multi meter. the voltage was slowly discharging. Now... i disconnected the battery and plugged it into a 2nd gen ipod mini and did the same thing. The battery showed a slow charge as tested with the meter. once the battery charged to full 3.7v i then put it back into the 3rd gen and powered it on only to the same effect with no battery charge indication and also a slow drain with the meter test. i've tried this on 3 or 4 different 3rd gen logic boards that i have and with the same results. I'm confused *** is goin on here. any replies please. thanks.

Just how its logic board is programmed I guess.
They make splitter cables which is a firewire and usb cable in 1, so if you have a wall charger you can charge and sync via USB at the same time.

Anyone have heat issues on 2011 MBP, WITHOUT the CPU being used at 100% ?

I hear many people having heat issues with the 2011 MacBook pro. All have mentioned some process using 100% of CPU. I wonder if anyone has heat problems even though the CPU is not being used at 100%. This would shed some light as to whether the problem is related to software or hardware.

Mine too. Get a inferno hot, and i cant use Firefox anymore, because the fans stars in less than one minute.
Everything started after the instalation of the OS X LION.

IOS 6.1.2 Upgrade- Battery Drainout, Apps Crashing, Battery Charging issue

After my iOS 6.1.2 upgrade Battery drains out very very fast and Apps Crashing on frequent basis. Called up apple but in vein... Any Workarounds here ?
Till iOS 6.1.1 it was perfectly fine.
The problem is more pathetic with the battery charging. Even though I chagre it for hours, it just drains out in the next couple of hours...

The same problem here.. its just goes on draing out and out...
I have tried several ways of downgrading it but failed..
Try contacting Apple Support in your country.... Else it seems we have no other way then to wait for the 6.1.3 upgrade..
Anyone with any workaround ?
