Strange behaviour on low battery...

Hello all!
I tried calibrating my battery and ran into this.
The instruction comands to use the notebook until it fully drains the battery and automatically goes to sleep.
But, in my case, a minute after the low battery warning, it turned off instead falling asleep. I have no idea as to what kind of problem (PEBKAC?) it is.
As the warning says, it should go to sleep to keep the contetns of RAM, and this behaviour does not seem to be customizable, so I was a bit disappointed having found it had turned off...
Also I am not sure about the step #5 of battery calibration (as it's presented Mac Help): "Turn off the computer or allow it to sleep for five hours or more", it says, and I am not sure as to what "for five hours or more" is related to: to keeping it in sleep mode, or to both sleeping and turned off?
(From the common sense's viewpoint, it should mean to keep it turned off or sleeping for five hours, but I am not sure...)
Thanks in advance,
Anton

This may occur if you have Battery update 1.3 installed.
If you have the Santa Rosa MacBook “New Model” you may not need to do this. Some people have reported that once the 1.3 bundle was removed on the SRMB they could not get the battery update 1.2 to install.
Check and see if you have battery update 1.3 installed. Try these two locations for it. It will be one or the other.
MacBook/Library/System/Library/SystemConfiguration/BatteryUpdater.bundle
MacBook/System/Library/SystemConfiguration/BatteryUpdater.bundle
Leopard installs it. It is the MacBook Pro update.
If it is 1.3 drag it to the trash and then reboot. After you reboot you will be able to empty the trash. Once you have done that run software update and it should install Battery Update 1.2. You should reset the SMC (System Management Controller) after doing this.
Also I am not sure about the step #5 of battery calibration (as it's presented Mac Help): "Turn off the computer or allow it to sleep for five hours or more", it says, and I am not sure as to what "for five hours or more" is related to: to keeping it in sleep mode, or to both sleeping and turned off?

It means either one will work. If you let it sleep for five hours or if you turn it ff for five hours the same goal will be accomplished. This lets the chemistry settle. I prefer to turn mine off completely once it goes to sleep.

Strange low battery warning...

Evening all.
I recently bought a new Nike+ sensor for my touch as the battery died in the old one.
I successfully paired the sensor with my touch but when I started the app the low battery warning still showed up! thinking this was wrong, given it was a new sensor, I went for a quick jog, calibrated it and continued jogging. when I had finished it said I had done 0 miles!?!
Now thinking it was a duff sensor I took it back to the shop and got a new one. paired it again and the low battery still comes up!!
Could this be a software problem? I have paired it several times and the warning still comes up and after a jog it records a distance of 0 miles
Anyone have any ideas??
Thanks,
Andrew

When I took the above stats, I had recharged the battery just onced. Now I've gotten up to two recharges. I think you are correct, it takes a few cycles to stabilize. Thx for the comment.

My iPod says the battery is low, the apple symbol appears and then cycles back to low battery message?

My older iPod classic says when I dock it either with charger or hooked up to computer that the battery is low, the apple symbol appears, you can hear a whirring sound (hard drive coming on) then a clicking sound and then back to low battery message. Has been doing this for the last week.

Hey there Kevin,
It sounds like your iPod Classic is exhibiting some unexpected behaviour when you have it connected to your computer with the usb cable. I suggest the troubleshooting steps in the following article to help troubleshoot the device:
iPod classic Troubleshooting Assistant
http://www.apple.com/support/ipod/five_rs/classic/
Start by resetting the iPod, then retesting the issue.
Reset
To reset your iPod:
1. Toggle the Hold switch on and off. (Slide it to Hold, then turn it off again.)
2. Press and hold the Menu and Center (Select) buttons simultaneously until the Apple logo appears, about 6 to 10 seconds. You may need to repeat this step.
Tip:
If you are having difficulty resetting your iPod, set it on a flat surface. Make sure the finger pressing the Select button is not touching any part of the click wheel. Also make sure that you are pressing the Menu button toward the outside of the click wheel, and not near the center.
If the above steps did not work, try connecting iPod to a power adapter and plug the power adapter into an electrical outlet, or connect iPod to your computer. Make sure the computer is turned on and isn't set to go to sleep.
Thank you for using Apple Support Communities.
All the very best,
Sterling

Screen says "Unable to listen to music; low battery" & won't charge?

My niece just called me with a problem I could not find a solution to doing a search.
She said she was listening to a song when her Nano stopped playing. When she looked at the screen, it said "You Can't play music, your battery is dead". It appeared for about a minute, then disappeared.
She plugged it in via the A/C wall adaptor, but the charging icon is not showing on the screen.
I told her to attempt a restart, but nothing happened. I asked if she attempted to charge it using the computer. That had also been tried before contacting me, and no icons appeared then either. Initially, my thinking was that it would need to be connected to the charger for a while before it had enough energy to show anything, but she said that it's been connected to the wall charger for over 3 hours now and that's why she decided to call me. Unfortunatley, we live a few thousand miles apart, so I can't run over and see it. And yes - I did have her check the hold button & that's not on either (see; I read these boards & do searches when I have questions! LOL)
Any ideas are greatly appreciated, as I'm at a complete loss. I have never heard of an iPod, Nano or regular, displaying such an interested message (I asked over 3 different times, and each time she repeated the same thing - unable/can't listen to music, low battery - then died).
Hopefully, someone can answer so I can regain my iPod Goddess status in her eyes =) I was floored when I did a discussion search and couldn't find the answer!
THX!

Hi Menhem,
It is unfortunate that the automatic calibration didn't complete. I would recommend going ahead and trying the Manual Calibration steps at the end of the document Testing and Calibrating the Battery (Windows 7), then go back to using the notebook as you normally would and see if the behaviour of the battery and charging system changes at all, you could also run the battery test again to see if you get a different result. If it improves great, but if there are still problems, try the automatic calibration one more time to see if it will complete.
Another thing to do is to make sure you are up to date with your BIOS, the latest BIOS for your model is F.52, which you can find at the link below, but it is relatively old at this point, so I would thing that you probably already have it on your PC. In general I would recommend running the HP Support Assistant application, and letting it check your PC and keep it up to date with all the necessary drivers.
How long have you had the notebook? Batteries do degrade over time with normal usage, and if you have had the notebook for awhile, and have put the battery through many charging cycles, it may just be time for a new battery. Check out Purchasing a Replacement Battery for instructions on finding a replacement battery. Some other documents to review are Improving Battery Performance (Windows 8, 7, Vista) and Understanding Lithium-Ion and Smart Battery Technology, both of which may have some good information to help you with your issue.

Font has a strange behaviour

One of my fonts has a strange behaviour. Some characters print perfectly on screen but not on the printer, neither in the preview ???
I tried to de-install and re-install that particular font, but that did'nt help.
any clues ? thanks,
MJ

Here's the problem. It's a complete piece of junk.
The baseline is so far off on zero through nine that they're being just about pushed off the chart. Next, look at the glyph names. A-H are correct. From there on, you get some sort of bizarre numbering where the rest of the upper and lower case letter designations should be.
That this font ever worked is amazing.

Strange behaviour with firefox

In all my flash movies I've a strange behaviour that happens
only whit Mozilla Firefox.
When I go over a clickable area it just doesn't work and it's
located lower than expected,
with Internet explorer and opera I don't have this problem.
The clickable areas are movieclips with on(release) script
set.
thanks

Are you using a percentage size of the flash object? E.g.
height=100%?
This is known to cause problems. You could omit those by
setting the height of the <body> tag to 100%, too (weird, I
know). Or delete the very first line in the html document, the one
that sets the doctype

Macbook shuts down on low battery

Hi!
My macbook powers off on low battery several minutes after low-battery alert. So nothing gets saved if macbook was left without power for a long period of time.
About first 3 month when it was new it went to sleep on low battery. But what happened now and how can I fix such a behaviour?

I believe I have found the problem...
If your battery is 0102 or 0102a firmware (check in System Profiler), then I believe it is the culprit; I have been through 4 batteries, and the only two that worked were 0110 firmware.
Another thing....if you have Secure Virtual Memory on, turn it off. I've noticed that Safe Sleep on low-battery doesn't seem to function if SVM is turned on; however, if I have SVM off and a battery with firmware 0110, it works dandy every time. I've tried SVM both OFF and with it ON with a firmware 0102 battery, and it still gives the same result--shuts down instead of hibernates.
I don't know if that will fix it for everyone, but it certainly fixed it for my last-gen Blackbook! (knock on wood)

Very Low Battery / Resetting issue - lets make Apple fix this!!!

There appears to be a lot of posts within the last few weeks about the "Please wait, very low battery" message and constant resets EVEN ON A FULL BATTERY. I too have begun to experience this problem. I can only think that there is some kind of bug that has been introduced with the latest firmware and itunes combo. Can anyone that it experiencing this issue, PLEASE put your experiences in a reply to this thread. As an addition to my post below, I have also heard that using the prior version to the latest Itunes in conjunction with the latest may also be the root of this problem. I have been using two itunes, the latest at home and a slightly older one at work. Can anyone shed anymore light on this possibility?
This is from a reply post I made earlier tonight:
I noticed my ipod 5th gen 60 gig was strangely in the red on battery life, so I connected it to my macbook pro and answered a few emails. I then noticed out of the corner of my eye that the ipod resetting. Weird! I had never seen it do this while attached to the computer. So, I went back into itunes and it said something about not disconnecting the device physically - some how the pod had reset and disconnected itself. So, I re-attached it, and moments later, it reset again. Instead of attaching to the computer, I attached the pod to a wall powered usb charger (non-official). After a few minutes, the pod said it was fully charged (weird), so I disconnected it. I thought I should check to see if it was playing music ok and started playing a song. It seemed ok, so I skimmed through a few tracks. Soon the ipod reset itself and started to continuously reset as if in a loop. After several reset attempts (menu and select) I was presented with a "Please wait, very low battery" message screen...
Hmmmm. I thought I should attach it to the wall charger and leave it to re-charge, thinking that the battery must be just plain out of juice. I got past the very low battery message and into the menu with a reset. Strangely, the battery showed as being fully charged... Disconnecting the pod and playing several songs again, the unit reset and showed the low battery message... Leaving the pod attached to the wall charger, even though it said it was fully charged, didn't remedy the problem. More resets when playing a song or two.
Initially I thought that it was a faulty battery. But, before I jumped to conclusions, I googled the above message. This showed me that this is a reasonably common issue with several possible causes. Some of the suggestions to remedy the issue included:
* Reset the ipod - nope, same problem
* Restore the ipod - did this first up... No go
* Put the unit into disk mode attach and restore - nope
* Drain the battery completely and then re-charge on wall charger - nope
* Open the unit, disconnect the battery, and re-attach - I really thought this would work, but nope.
* Disconnect unit, insert wall powered usb, start unit to reset it - nope
* Buy a new battery - NOPE, same thing keeps happening even with a FRESH battery!!!
* Put the unit into diagnostic mode and then charge... This kind of worked in the fact that it actually charged the new battery...
It appears to me that the battery status is all out of whack. The OS seems to think that the battery is completely full, and hence, doesn't take a charge. Equally, even though it says there is a full charge, after the unit plays one or two tracks (requiring a few harddrive seeks I suppose) it will exclaim that there is no battery remaining, reset loop and eventually enter "very low battery" mode. It does the latter even if the battery is new and appears to have been charged (via the diag screen).
So, where to from here... Well not entirely sure, but I reckon that what I have to do is drain the fully charged battery WHILE the unit is active. Perhaps then, it will re-calibrate its internal battery meter... Right now, I have been able to put the pod into disk mode and it is actually showing a battery icon WITHOUT the fully charged symbol (the little plug icon). It also shows a slight depletion in battery remaining. My hope is that this depletion will get bigger over the next few days and, if it does, it may right the funny loop-like state it is in.
Has anyone got ANY other ideas as to how to fix this problem. As a side note, I updated the pod to firmware 1.3 recently. I am considering a restore using an older firmware. Where can I track down 1.2? Can I press the option key and click restore to choose an alternative restore image from the 1.3 already in itunes?
Any suggestions/help is EXTREMELY welcome as I am almost about to give up...

I think my problem actually might be the same ... the other day it was full battery one minute, and the next it was saying "Please connect to power,low battery". I wasn't near a power source, so i just left it. Then it started making this funny whirling sound and the screen went silvery blank, so i figured it was the hard drive crashing. I hooked it up to the computer overnight and the next day I could at least get the apple on the screen to show up and the computer would recognize it somewhat. When it's hooked up to the computer it goes from the apple screen, to please wait, very low battery, to the regular screen with a fully charged battery sign, to the "do not disconnect" screen with the battery charging.. When the "do not disconnect" screen appears, sometimes the computer recognizes it. But when it comes up it first says that an unknown error (-124)has occured and the ipod cannot be synced. And then it says the disk cannot be read or written to. After I press okay again, the screen goes to the apple and back to the please wait very low battery screen... and then in tunes it says the ipod cannot be synced because the required folder cannot be found. Then it comes up again and says iTunes cannot read the contents of the iPod. Go to the Summary tab in iPod preferences and click Restore to restore this iPod to factory settings. Now I would try to do that, but I don't have a summary tab in the preferences, if the preference tab they refer to is under the edit section. For the couple of seconds the my ipod settings appear on the screen, the files on it aren't even the same as before. It says I only have 7.78GB of only songs on my 30GB. Not only do I have more than 7.78 GB of songs normally on my ipod, I have videos and games that also should appear. Everytime it reconnects however, the GB go down? Now its at 6.07GB
It also makes this beeping sound randomly. Sometimes it when the ipod goes into the very low battery screen, but sometimes it beeps during the apple screen, or sometimes during the do not disconnect screen.
The most frustuating thing for me is that about mid-March I sent my iPod away to get a new battery before my warrantee was up. I got it back the first week of April, good turn around period, but instead of getting my old ipod back, I got a refurbished one. Now this is happening to it, and my warantee is already up. I know it can't be the battery that's wrong with it, there may be something wrong with it, but I'm sure they know better than to give me an ipod with a dead ipod.
Now it's coming up as 5.77 GB . . .
When it first happened, I was hoping that I could simply hook it up to the computer and click the restore button. This is impossible however because I can never get to the restore button before the computer unrecognizes my ipod.

[Solved] Warn on low battery/halt

Hi,
This is my third day of arch, and on two occasions so-far I have forgotten that my laptop is unplugged and so has run out of battery and turned off. I thought that maybe it was time to do something about it.
How do I go about calling a script (i.e. to halt or to play a sound or something) when the battery is low. (1)Would /etc/acpi/handler.sh be the right place to put things in? (have got the laptop dimming when ac power is removed, and the screen turning off when lip is closed)
From perusing the forums it seems someone mentioned laptop tools, however from reading documentation on it, in various places, it scares me a little. Things about killing HDs. (2) Can I be sure that I have disabled any RAM-killing features? Also, from looking in /etc/laptop-mode/laptop-mode.conf it seems that it only supports hibernate on low battery, however this is another thing I have yet to set-up. (3)Can hibernating be done with a swapfile smaller than my ram (RAM is 1.5gb, swap 1gb)? If no, (6) can I change my swapfile size w/o losing data on my /home partition (the partition preceding the swapfile)?
Thanks if you managed to get through the jumble above. I fail epicly at forum posts. Never can seem to make them totally comprehensible.
Edit: If relevant: Laptop is HP 530, running on Openbox.

Thankyou so much. I now have hibernate working like a charm. This is why I love arch linux - useful advice in 4 hours
What do I need to watch out for then in the laptop mode conf to ensure nothing is done to my HD. Currently my conf looks like:

# LCD brightness settings
# Using these settings, you can make laptop mode tools automatically adjust
# your LCD's brightness settings. The settings are extremely simple -- they
# only allow for the execution of a command, nothing more. The reason for this
# is that LCD brightness settings are very different between laptop vendors.
# Suggestions for commands:
# * If your system has the file "/proc/acpi/video/VID/LCD/brightness" (VID may
# be VID1 or similar), use this file as BRIGHTNESS_OUTPUT, and use
# the command "echo <value>". The possible values can be listed using the
# command:
# cat /proc/acpi/video/VID/LCD/brightness
# * If you have a file /sys/class/backlight/.../brightness, then you can use
# that file as BRIGHTNESS_OUTPUT, and the command "echo <value>".
# As far as I understand it the values are between 0 and
# the value contained in the file /sys/class/backlight/.../max_brightness.
# * For Toshiba laptops, use the command "toshset" with the -lcd or -inten
# command. Read the toshset(1) manual page for more information on the
# parameters for this command. If you use this command, set
# BRIGHTNESS_OUTPUT to "/dev/null".
# Should laptop mode tools control LCD brightness?

IPhone 5 will not turn on. Endless Low battery, Apple Logo, reset loop

Today I dropped my phone, not a big drop, only about 2 feet. I had a lifeproof case on so I thought to myself," No big deal" To my shock and disbelief, my phone would not turn on! I tried to plug it in to a charger to try to start it. It immediately came on with a low battery symbol. I thought that was strange as it had a 70-80% charge on it. But I was hopeful. It then displayed the Apple Logo and I thought I was safe. Then after about 5 sec it went blank. Then the Low Battery symbol came on again. Then the Apple Logo for a few seconds, ... then Off. It does this over and over in an endless loop. I dont know where to go from here. I tried googling the problem but didn't come up with much. I tried holding the home and power button for 20-30 seconds like one video recommends but that did nothing. It only loops if its plugged in to a charger. If its not plugged in it is just off, no activity at all and it will not turn on. Any help will be much appreciated.

Just to follow up if anybody else has this problem.
The drop must have ruined the battery. After taking it to a local repair shop to get serviced, as suggested by Ingo2711, the phone is back to 100% after a new battery was installed. $50.00 bill for a new battery is not to bad at all to fix my phone.

Low battery, apple icon, sad mac

I just got my "new" used 4th gen ipod. I turned it on got the apple logo and then a sad mac with an exclamation point. I'm charging it to see if its an issue with the battery (the battery is showing low charge). What I can't understand is why the battery charging icon appears and then intermittingly the apple logo is followed by the sad mac and then back to the battery icon? Is the sad mac because of the low battery or another issue? It's only been plugged in an hour and I have not reset it. What's happening? Thanks

Low battery icon does not equal to sad iPod, which means something wrong on the HD of the iPod, and its OS does not manage to process. However, most of the sad iPod problem do caused by the low battery. See the following helps
Hello,
If a sad iPod icon or an exclamation point and folder icon appears on your iPod’s screen, or with sounds of clicking or HD whirring, it is usually the sign of a hard drive problem and you have the power to do something about it now. Your silver bullet of resolving your iPod issue – is to restore your iPod to factory settings.
http://docs.info.apple.com/article.html?artnum=60983
If you're having trouble, try these steps at different levels one at a time until the issue is resolved. These steps will often whip your iPod back into shape.
Make sure you do all the following “TRYs”
A. Try to wait 30 minutes while iPod is charging.
B. Try another FireWire or USB through Dock Connector cable.
C. Try another FireWire or USB port on your computer .
D. Try to disconnect all devices from your computer's FireWire and USB ports.
E. Try to download and install the latest version of iPod software and iTunes
http://www.apple.com/itunes/download/
For old and other versions of iPod updater for window you can get here

F. Try these five steps (known as the five Rs) and it would conquer most iPod issues.
http://www.apple.com/support/ipod/five_rs/
G. Try to put the iPod into Disk Mode if it fails to appear on the desktop
http://docs.info.apple.com/article.html?artnum=93651
If none of these steps address the issue, you may need to go to Intermediate level listed below in logical order. Check from the top of the lists to see if that is what keeping iPod from appearing on your computer in order for doing the Restore.
Intermediate Level
A. Try to connect your iPod with another computer with the iPod updater pre-installed.
B. Still can’t see your iPod, put it in Disk Mode and connect with a computer, instead of doing a Restore on iPod Updater. Go and format the iPod instead.
For Mac computer
1. Open the disk utility, hope your iPod appears there (left hand side), highlight it
2. Go to Tab “Partition”, click either “Delete” or “Partition”, if fails, skip this step and go to 3
3. Go to Tab “Erase” , choose Volume Format as “MAC OS Extended (Journaled), and click Erase, again if fails, skip it and go to 4
4. Same as step 3, but open the “Security Options....” and choose “Zero Out Data” before click Erase. It will take 1 to 2 hours to complete.
5. Eject your iPod and do a Reset
6. Open the iTunes 7 and click “Restore”
For Window computer
Go to folder “My Computer”
Hope you can see your iPod there and right click on the iPod
Choose “Format”. Ensure the settings are at “Default” and that “Quick Format” is not checked
Now select “Format”
Eject your iPod and do a Reset
Open the iTunes 7 and click “Restore”
In case you do not manage to do a “Format” on a window computer, try to use some 3rd party disk utility software, e.g.“HP USB Disk Storage Format Tool”.
http://discussions.apple.com/thread.jspa?threadID=501330&tstart=0
C. Windows users having trouble with their iPods should locate a Mac user. In many cases when an iPod won't show up on a PC that it will show up on the Mac. Then it can be restored. When the PC user returns to his computer the iPod will be recognized by the PC, reformatted for the PC, and usable again. By the way, it works in reverse too. A Mac user often can get his iPod back by connecting it to a PC and restoring it.
Tips
a. It does not matter whether the format is completed or not, the key is to erase (or partly) the corrupted firmware files on the Hard Drive of the iPod. After that, when the iPod re-connected with a computer, it will be recognized as an fresh external hard drive, it will show up on the iTunes 7.
b. It is not a difficult issue for a Mac user to find a window base computer, for a PC user, if they can’t find any Mac user, they can go to a nearest Apple Shop for a favor.
c. You may need to switch around the PC and Mac, try to do several attempts between “Format” and “Restore”

Advance Level
A. Diagnostic mode solution
If you have tried trouble shooting your iPod to no avail after all the steps above, chances are your iPod has a hardware problem. The iPod's built-in Diagnostic Mode is a quick and easy way to determine if you have a "bad" iPod.
You need to restart your iPod before putting it into Diagnostic Mode. Check that your hold switch is off by sliding the switch away from the headphone jack. Toggle it on and off to be safe.
Press and hold the following combination of buttons simultaneously for approximately 10 seconds to reset the iPod.
iPod 1G to 3G: "Menu" and "Play/Pause"
iPod 4G+ (includes Photo, Nano, Video, and Mini): "Menu" and "Select"
The Apple logo will appear and you should feel the hard drive spinning up. Press and hold the following sequence of buttons:
iPod 1G to 3G: "REW", "FFW" and "Select"
iPod 4G+ (includes Photo, Nano, Video, and Mini): "Back" and "Select"
You will hear an audible chirp sound (3G models and higher) and the Apple logo should appear backwards. You are now in Diagnostic Mode. Navigate the list of tests using "REW" and "FFW". The scroll wheel will not function while in diagnostic mode. For further details on Diagnostic mode can be found at http://www.methodshop.com/mp3/ipodsupport/diagnosticmode/
Try to do the 5in1, HDD R/W and HDD scan tests. Some successful cases have been reported after the running the few tests under the Diagnostic mode. In case it does not work in your case, and the scan tests reports show some errors then it proves your iPod has a hardware problem and it needs a repairing service.
B. Format your iPod with a start disk
I have not tried this solution myself, I heard that there were few successful cases that the users managed to get their iPod (you must put your iPod in disk mode before connecting with a computer) mounted by the computer, which was booted by a system startup disk. For Mac, you can use the Disk Utility (on the Tiger OS system disk), for PC user, you can use the window OS system disk. Try to find a way to reformat your iPod, again it does not matter which format (FAT32, NTFS or HFS+) you choose, the key is to erase the corrupted system files on the iPod. Then eject your iPod and do a Reset to switch out from Disk Mode. Reboot your computer at the normal way, connect your iPod back with it, open the iPod updater, and hopefully your iPod will appear there for the Restore.
If none of these steps address the issue, your iPod may need to be repaired.
Consider setting up a mail-in repair for your iPod http://depot.info.apple.com/ipod/
Or visit your local Apple Retail Store http://www.apple.com/retail/
In case your iPod is no longer covered by the warranty and you want to find a second repairing company, you can try iPodResQ at your own risk
http://www.ipodresq.com/index.php
Just in case that you are at the following situation
Your iPod warranty is expired
You don’t want to pay any service charges
You are prepared to buy a new one
You can’t accept the re-sell value of your broken iPod
Rather than leave your iPod as paper-weight or throw it away.
You can try the following, but again, only do it as your last resort and at your own risk.
Warning !!!! – It may or may not manage to solve your problem, and with a risk that you may further damage your iPod, which end up as an expensive paper weight or you need to pay more higher repairing cost. Therefore, please re-consider again whether you want to try the next level
Last Resort Level
1. . Disconnecting the Hard Drive and battery inside the iPod – Warning !! Your iPod warranty will be waived once you open the iPod.
In Hong Kong there are some electronic shops offering an iPod service for Sad iPod, the first thing they do is to open up the iPod’s case and disconnecting the battery and the Hard Drive from the main board of the iPod. Wait for 5-10 minutes and reconnecting them back. The reason behind which I can think of is to do a fully reset of a processor of the iPod. In case you want do it itself and you believe that you are good on fixing the electronics devices and have experience to deal with small bits of electronic parts, then you can read the following of how to open the iPod case for battery and HDD replacement (with Quicktimes)

2.Press the reset button on the Hard Drive inside the iPod – Suggestion from Kill8joy
http://discussions.apple.com/thread.jspa?messageID=2438774#2438774
Have I tried these myself? No, I am afraid to do it myself as I am squeamish about tinkering inside electronic devices, I have few experiences that either I broke the parts (which are normally tiny or fragile) or failed to put the parts back to the main case. Therefore, I agree with suggestion to have it fixed by a Pro.

I am not suggesting that you should follow as well, but just read them as your reference. You are the person to make the call.
Finally, I read a fair comments from dwb, regarding of slapping the back of the iPod multiple times
Quote “This has been discussed numerous times as a 'fix'. It does work, at least for a while. In fact I remember using the same basic trick to revive Seagate and Quantam drives back in the mid to late 1980's. Why these tiny hard drives go bad I don't know - could be the actuator gets stuck in place or misaligned. Could be the platter gets stuck or the motor gets stuck. 'Stiction' was a problem for drives back in the 80's. Unfortunately the fix can cause damage to the platter so we temporarily fix one problem by creating another. But I know of two instances where a little slap onto the table revived the iPods and they are still worked a year or more later.”UnQuote

'Stiction' was a problem for drives back in the 80's. Unfortunately the fix can cause damage to the platter so we temporarily fix one problem by creating another. But I know of two instances where a little slap onto the table revived the iPods and they are still worked a year or more later.”UnQuote

Disable Wireless Trackpad low battery notification?

That's basically it. Does anyone know how to?
The low battery message keeps poping up on the notification center every 10 minutes - and I'm still up to 15% battery. I don't want to use the trackpad for the next week having to close the notification every 10 minutes.
Thanks.

Yep, super annoying as I get at least another 2 months out of the battery. Two months of constant reminders.
Surely there must be a way to stop this? Or at least to modify it's behaviour so that it only comes up when down to 5% and only reappears once per day?

M70 freezes when connecting AC Adapter after low battery warning

When I get the low battery warning, I connect the AC adapter but when I switch the power on, the laptop screen goes blank. The DC in LED lights up, the Power LED stays on and the Battery LED comes on but I cannot use any keys on the keyboard, the laptop has frozen. Any ideas?

Does this happen when you connect the small plug directly to your laptop or the mains plug?
I noticed similar problems (usually shutdown) when connecting/disconnecting the mains plug. This does not occur when the power adaptor is plugged in and I plug the power connector at the laptop in/out. I guess there is a problem with the transient behaviour of the power adaptor & the power detection in the laptop.
This applies to Satellite M60. I recall no similar issues with an older Sat 3000.
