Battery meter reads only 0-1%, or 99%.

OK, well this a little hard to explain but I'll try my best:
Basically, one day a couple weeks ago I took my PowerBook to school and had it in class and basically drained the battery completely to 0%, managing to still continue working about 30-35 minutes after reading 0%. OK, so it powers itself off and goes to sleep. Understandable. I put it away and charged it back up at home later that night.
The problem now is that the battery meter up at top no longer gives me accurate readings on the battery. When the battery has been charging for about as long as it usually would take for it to say 100%, it stays at like 2%. Sometimes, it'll just jump right from 1 all the way to 99%. Ok, like right now it said 2% but now went to 1% even though the AC adapter is still connected and the light has remained on. I have not seen the percentage say anything between 3 and 98% ever since the day I used it in class. It will go from 0-2%, then occasionally to 99% and back to 2, 1, 0. To make this problem seem even a little more strange, before this problem started showing, the computer would rarely start itself up again in the morning without being plugged into the wall first. Essentially, it would become "cold" overnight, and I'd have to plug it in first to the wall to start up. NOW, this thing always wakes up from sleep in the morning or basically whenever no matter how little battery life I think it has.
I got my computer in Jan/2004 and it still has the original battery. Needless to say, I was already getting some pretty short battery life. I'm not sure what the proper procedure on batteries in these things are, if I should have replaced it by now with a new one?
HELP!
--DANIEL
(FYI, the meter has now been stuck back at 2% for about the last 10 minutes.)

IPhone Battery Meter Never Goes Down

My battery meter will only show 100% charge...then all of a sudden the "please charge" will come on the screen. When I plug it in, the battery meter again shows 100% charge. When I charge it all night it holds a good charge, but I have no indication of when my battery is going to die.

I have experienced the same problem. I actually didn't even get a warning, power just ran out I the phone was dead until I charged for 20 min.

Set Cell or Row to read only if certain condition is met

Greetings,
As the subject suggest, I need to set Cells or Rows to Read Only or "Gray out" If Certain attribute doesnt contain any value.
The requirement is to search for records of certain range and display it in the table. And the records will not be editable (read only) if certain attribute/field of the record is NULL. In another words that particular row will be gray-ed out.
Right now I am able to extract out the range of records out and display it in the table but I am not able to set the display of the records/ rows to read only. Do note only certain row needs to be set to row only depending on a particular attribute.
I was to code these in WDDOMODIFYVIEW()... anyone have any solution to this? Points will be given of course. ")

Please dont use the DOMODIFY method for such changes.
The Properties mapped to the context are designed for exactly this purpose.
Your context node should be extended with another attribute. Eg attr_y_Read_only.
The read_only or enabled attribute of field y would then be mapped to this attribute.
Depending on cell editor type it may be called enabled or read only.
You then set this new attribute to true or false appropriately for each element in the node.
This new attribute, although inside the node, need not be displayed as part of the table.
It is there to help control fields in the each element.
Regards
Phil.

IPod passes Apple battery test but only lasts 2hrs during normal use

I have a 1st generation iPod mini; the battery has been acting up lately. I have done Apple's battery test a few times; each time the battery lasts for 6-8 hrs. However, during normal use, it lasts only 1.5-2hrs, even after a full charge.
I have this problem even when the backlight and the EQ is off. Also, the battery dies, even though the battery meter is half full. If I immediatly turn on the iPod, the meter is empty, but after 20 min, it's half full again. When I try to play music, it turns off.
On top of this, the battery takes a minmum of 8hrs to fully charge!
Please help...!

My ipod mini 2nd generation was like this too.. it would reset itself resetting the time also for no reason every 20mins.. and it wouldnt hold a charge.. i sent it in thursday and i should get it back this week.. if your ipod is in warranty.. send it back asap!

Previous Meter Reads and Usage are not correct after meter Proration

It seems that during proration there are two meter reading available the one with the Meter Reading type as 03 ( Automatic Estimation ) and other is Meter Reading type 01 - MR By employee that is being retrieved. The 03 reading type seems to be the reading after the proration and the o1 reading is the reading done before the proration . The reads are coming out on our invoices incorrectly. Usually there will only be one Meter reading to be picked up. but it seems do proration it splits meter into 2 entries. The entry with with metering type 01 has the correct previous and current meter reads but incorrect usage. The entry with meter read 03 has the incorrect previous meter read and correct current meter read but incorrect usage. Our print work bench generated fiction is calling SU_DB_ERCHZ_SELECT_BILL_NEW to retrieve the values but the values that it retrieves are not correct., The second records is being put on the invoice. The form that exist in the SU_DB_ERCHZ_SELECT_BILL_NEW is called db_erchz_select_join and is used to retrieved the usage and meter reads.. This information is then passed to out user exit.
The previous meter read should be 5,073,998     and the usage should be 7500

Why is the battery meter so annoyin?

Ok heres the thin, i got my 5g black 30gig ipod two weeks ago...everythin was fine, until after the first full charge i noticed after about an hour of music the battery meter was down to 3/4 of a charge and kept goin down dramatically, after reading some of the disscussions i did the update and charged it untill it said full, so then after about 4 1/2 hours its in the red, so obviously it still goes down quite fast, to calibrate it at the moment by runnin it till dead, so has anybody else had this problem, and what happened to you....another thing what is the best way to charge it...through an ac adapter or computer.

ok...using my ipod normally (between .5 and 1 hour a day right now) the battery lasted about 8 hours....so it ran for 3.5 hours in the red...this is really dissapointing although it says that it will run 8-12 hours, but also realizing that was the first time doin a charge discharge cycle to try and calibrate it but after charging it the meter is doin the exact same thing...after fully chargin it, the second i start playin music the meter goes down...now the backlight timer is 2 seconds, the eq is off, and the library is on shuffle...and i only change songs once in a while...so why am i only gettin 8 hours?

2.1 firmware update displays incorrect battery meter

After installing firmware 2.1 on my iphone I started noticing my battery meter displaying the incorrect charge level. I charged it in full yesterday, and this morning I still had more than half the battery meter. I checked 10 minutes later and the meter was now showing 10% left with the red battery meter.
I went ahead and charged it again , used it for a while and now noticed that the battery meter is not only showing the incorrect amount left (still) but shows a different battery status on different menu screens. Shows battery meter to be full in the home screen and half the meter on an app, email ,etc.
Firmware 2.1 has definitely messed up the meter!
inaccurate reading on the battery meter , someone else has to be experiencing this same problem.
let me know if someone else has this same problem !

try draining out the battery first and then recharge it, see if that shows an accurate. I had that happen to me on the 2.02 update. The battery meter was inaccurate. Like when i reached 20% it was actually at 50% when i plug it in to charge. So i did sent them a feedback about it. So I'm hoping that the 2.1 fixes this issue. So far my battery is showing at 100%.
Usually for me at the end of the day after a full charge in the morning, the battery meter would go down 1 bar. So i'll have to wait and see.

IOS 4.1 on 3G - Battery Meter Wrong

Has anyone had problems with the battery meter after updating to 4.1? The meter is correct while discharging, but not while charging. To get an accurate reading after a charge, the only solution I've found is rebooting the phone. I've tried several times with the same result. Also, I've tried draining to see if recalibration was needed or something. Any help would be appreciated.

Greetings,
There is likely no issue with your phone/software, other than you may need to calibrate the meter. That old phone can have a meter go out of calibration with the installation of iOS 4.1, especially if you are going straight from 3.13.
All you have to do is to charge it up overnight, then run it down all the way until it shuts itself all the way off, not just go to sleep. After that let it rest a half hour or so, and fully charge it, without using it. It's best to plug it in, and then do a full shut down, and let it charge fully. The meter should be in calibration, after that.
I've seen some folks have to do this a couple of times, if they continually short charge it, but once is usually enough.
I wouldn't pay too much attention to what the meter says while it's charging, as other things are going on that will make the meter fluctuate a bit, since it's on.
Cheers,
M.

Time, airport, battery meter will not display.

Hey I have an ibook g4 that does not want to display the battery meter, sound volume, time & day. for some reason. I have looked all over system prefs and got nowhere fast. If someone can let me know whats up...please do. I have tried to right click over it and everything. thanks.

I'm not interested in ascribing blame either but waiting for Apple to fix something that isn't broken will only divert attention from seeking the problem's underlying cause. Assuming the AirPort Utility app on your Mac remains unaltered, it's exactly the same one everyone else is using. Should there be any doubt about that, reinstalling OS X will obviate any concern.

Clamshell - battery meter problem?

Somebody has to be able to explain this one to me...
I bought a used graphite 466 to hold me over until I can save up for a brand new laptop. It was running like a dream, at least until...
I turned it on one morning, as I usually do... and the battery meter was acting really weird... I still got my 4 hours of use out of it, but the meter very slowly ticked down to about 95%, then took a huge nosedive down to just 5% in an instant... I was forced to run off the adapter until my class was finished, and I brought it home...
I was at home, adapter hooked up so I could recharge it while I continued using it. The charge slowly crept up to maybe 9 or 10%, then jumped straight to fully charged. That was the point where I realized something was very wrong... so I scoured the support pages, and the discussions, to try to find something that matched what was happening with mine.
I did the PMU button, reset the NVRAM through open firmware... I even let the battery run down fully and took it out of the laptop for the night...but there was no change...
Next, I decided to download one of those programs to check the battery... and either I'm very confused, or the numbers just dont add up.
According to XBattery, my battery stats right now (fully charged and running off the adapter) are:
installed: yes
charging: no
charger: yes
battery %: 100
(so far, all makes sense... what a fully charged battery should say, I would think... but then it gets weird)
Max. cap: 3.600Ah
Curr. cap: 64.860Ah
Charge: 64.860Ah
(this part makes me think maybe the labels for these numbers are mixed up somehow... how could my current capacity be that far above the max?)
voltage: 16.858v (the adapter itself says it should be 18v, but this is close enough)
amperage: 0 (it's not currently drawing any power from the battery... i guess?)
cycles: 80 (charge cycles, I guess...sounds way too low for it to be a battery problem... )
Flags: 2d000005 (no clue... I'm sure they mean something, but I don't know what...)
Now, I'm no expert as to what all those numbers really mean, but my impression is that it's not a battery problem per se....
Anybody have any idea what's wrong with my machine? Is there something simple that I'm missing here?

I ran a terminal command to show my battery information:
"IOBatteryInfo" = ({"Capacity"=64860,"Amperage"=0,"Cycle Count"=90,"Current"=3363,"Voltage"=16415,"Flags"=754974725,"AbsoluteMaxCapacity "=3600})
While I'm no expert, I think I have at least some grasp of what it's saying...
Capacity is 64860mAh, which XBattery lists as 64.860Ah... different units, same thing...
Cycle Count is now up to 90... that's fine... I've charged and discharged a few times since last time I checked the count...
Amperage is at 0, even though the menu says it's charging... not sure how that is true...
Voltage is 16.415... not too far off from the 18v listed on the outside of the power adapter... that's acceptable...
For the flags, 754974725 in decimal is the same as 2d000005 in hex, which matches XBattery...
The part I don't get is... if I'm showing a charge of 3363 out of a max of 3600, why is it only at 5%? The only way it could be was if it was comparing the charge to the current capacity... 3363/64860, which is about 5.2%...
For some reason, the computer is not giving it more power, because it's so close to that 'assumed' capacity... 3600 space left on a 64860 battery, which would be around 95% charged... and that's before counting the 3363 I 'persuaded' the battery to accept... But when it checks capacity after I unplug the adapter, it is nowhere close to what the machine was 'assuming' while the adapter was connected...
I would think my computer (or any computer for that matter) would be smart enough to at least pose the question as to why the 'max capacity' is so far below the 'current capacity'... It's like saying 'This basket holds 36 apples maximum, but currently, it's holding 640+ apples... it doesn't really make much sense... There is no situation in which both statements could EVER be true for that one single basket, or my battery in this case...
You'd think an error screen would pop up or something: "The battery is currently sending unreliable and conflicting capacity data, so therefore, time and charge percentage are unable to be calculated in any reliable fashion..." Then it should instruct me on what to do to correct it... Or, at the very least, suggest that I call for assistance... right?
This issue has evolved from weird to downright annoying... I just wish I knew what the real problem was so I could fix it already!

Iphont battery meter not working/ push notifications not working/restarting over and over again.

A few weeks ago, I went on a vacation out of the country. I had my iphone 5 on airplane mode for a week. When I got back and turned it off of airplane mode, it started restarting over and over again right after being plugged into the charger. Eventually, it seems to get ahold of itself and stops turning on and off, but the phone battery meter freezes where ever it is at that point. If it has 100% battery, it says it has 100% battery until it dies. If it only has 1% battery, I'll leave it on the charger long enough to have 100%, but it will still say 1%. The battery life itself is not any different. According to the meter, my phone will stay on all day with 1%. Also, after being dead, my phone would turn on immediately after being plugged in (rather than waiting a few minutes to get enough charge as usual). I think this is because since my phone does not know how much battery it has, it thinks it has enough to turn on right away.
I visited the apple store, and they told me to restore it as a new phone. When I did this, it did not work at first. But after a day, my phone battery life meter started working normally again, and it stopped doing the turn on/turn off continuously thing. BUT imessage no longer worked. It said "waiting for activation" for two weeks. Also, push notifications no longer worked. Every time I openned an app, it would notify my that i could not have push notifications and to connect to itunes. Certain apps wouldnt work at all (snap chat, lulu). They would just give the alert about push notifications over and over again.
I wanted imessage back, so I restored my phone as new once again. This time, imessage, push notification, snapchat, ect. started working again. But, it has gone back to not knowing how much battery life it has and restarting over and over again after being turned on from a dead state. WHAT DO I DO?! I don't want to have either of these problems. It's kind of like my phone has a virus.
note: the first time i turned it on after coming back from vacation, it said "no sim card" for a few minutes.

Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Repair Database. If that doesn't help, then try again, this time using Rebuild Database.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. (In Library Manager it's the FIle -> Rebuild command)
This will create an entirely new library. It will then copy (or try to) your photos and all the associated metadata and versions to this new Library, and arrange it as close as it can to what you had in the damaged Library. It does this based on information it finds in the iPhoto sharing mechanism - but that means that things not shared won't be there, so no slideshows, books or calendars, for instance - but it should get all your events, albums and keywords, faces and places back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

Lying Battery Meter...any suggestions?

Hi,
I have a silver 2nd Gen iPod mini, 8 months old. Its battery meter lies to me. For example, once, it said that it was almost full; but it died after 10 minutes of usage, and when I turned it on, the battery icon came up and the screen read "please connnect iPod to power." how would I solve this problem? any suggestions welcome
thanks

oh..ic..
but is the latest updaters reliable? because I've came across many posts where owners of all iPods were outraged by the new updater...I personally had some trouble with it too, but I got it all sorted out.
By the way, this lying meter has been doing this since when I got it (I'm sure) but I've only started paying attention in the past 4 months. I've done several updates to the iPod since when I got it, and its still lying...but I'll try the latest updater again.
thanks

Battery meter haywire

Today, I was using my iPhone 3GS (3.1.2) regularly and I eventually found myself down to 11% by mid-afternoon (under this exact same usage per day, I am often around 60%).
I shut off my iPhone, and turned it back on, thinking this would solve the problem but it did not. Next, I plugged it into my charger and watched it charge rapidly to 19% within 2 minutes. Then, I disconnected it and played some music and it stayed at 19% even after five minutes of music playing (which is a good sign since a full charge should net 30 hours of audio playback).
I plugged it back into my charger and right in front of my eyes, I saw the battery meter jump from 19% to 55%. Instantaneously.
Is there a physical component of the battery meter gauge that could have gone bad? Is my battery going bad, after only a few months of use?

I'm not going to discount the "you have a bad battery" or "You have push applications draining the battery" theories. However, if the iPhone is not getting physically warm to the touch, then I'd discount the high-drain theories.
I've had battery gauge wierdness myself, with the % available plummeting very rapidly down to single digits, then *staying there* for hours.
In my case, this happened not long after I'd completely discharged the phone, then had a failure to re-start during the mandatory 10-min waiting with low battery sign as it was plugged in. I got a white-screen boot, which a hard reset (hold power and home button) fixed. But after that, battery gauge wierdness...
In my case, I did a restore-from-backup as a new phone with firmware reload, and then did a couple of complete charge-discharge cycles, and now the gauge is behaving relatively sanely.
I hypothesise that something in the firmware "learns" the battery charge characteristics and uses that to display percentage remaining, and that whatever code / data is associated with this is vulnerable to "mis-learning" or corruption.
In short: I don't think the battery gauge is always correct, but I don't think that this actually affects the battery life you get out of the phone too much.

Battery Meter Red, Not Charging when plugged

Last night i was using my phone to browse and surf the net. the battery was running out finally it gave me a graphic that i need to plug it in. The graphic was a plug + the electricity symbol. So i plugged it in and the plug and the electricity turned into just the electricity symbol. so i went to bed and when i woke this morning, the phone was on the same screen. It had the battery meter in red, the electricity symbol on the but no charge. So i checked the plug on the wall, and it works. So i decided to plug it in to the computer and still the same. No charge going through.....
I restarted it while still plugged and nothing.
so finally i restarted it, unplugged the cord....then replugged it and it finally started getting charge...
Has this happened to anyone? Or is there some kind of safe gaurd that i dont know about and just making a full of myself on here?

Ok I think I have an answer. This happened to me twice and both times, it resolved the same way.
CAUSE: Both times, this happened when I let the battery run down too much. I was playing a game or listening to music and ignored the low battery warnings thinking I could push it and eventually the iphone shut down. No problem, I thought. I can just plug it in and keep on going. But when I plug it in, the iphone won't charge ... like it normally does. I get the red battery meter and the plug and lightning symbol as previously described. The phone won't turn on. I tried resetting it several time - hard resets as well - with no response. Always to the screen with the red battery.
SOLUTION: What i did both time was to keep the phone plugged in for at least 4 hours and maybe even more. I noticed that the red battery symbol flashes when it is not plugged in but when it is plugged in - the red battery symbol does not flash. Even though the phone is non-responsive in every other way, it seems to recognize if it is plugged into a power source or not. So I kept it plugged in for several hours. By the way, the phone is totally unusable during this time.
After that time period - I did a hard reset and the phone booted up with the white apple symbol and I started recharging again - this time it took.
I did this TWICE so I think it will work in the future.
THEORY: I am not a computer person (I'm a gynecologist in real life) but I will try to explain this behavior as best as possible. I think when the battery runs down too low it shuts down. But it shuts down EVERYTHING! Even the software that charges up the battery - which is a bug that Apple needs to fix - but everything shuts down. So this may sound stupid but it seems that when it is shut down to this degree the phone does not know how to charge itself. That is why nothing works. The phone remains shut down. It does not reboot. It does not charge up. However, as noted above, the phone does seem to recognize when it is plugged in to a power source or not as indicated by the flashes on the red battery symbol. It flashes if it is not plugged in and it stops flashing when it is plugged.
Anyways, even though the phone does not know how to charge up, it is charging anyways - but only by a trickle. A microscopic trickle. And it takes a couple of hours via this trickle to charge up the phone to a certain level to be able to reboot. After the reboot - you have to charge up the battery again - but since the phone is now working, it knows how to charge itself up normally.
Again, this is an amateur theory but I can't explain this behavior any other way.

IPad 2 battery meter stuck, anyone else?

It seems after downloading a few apps and putting the iPad to sleep with wifi on the battery meter stops updating the next day when I wake it from sleep. I used to notice the ipad draining by 1% every 9 minutes, but now it has been 20+ minutes and no change. A reset seems to fix the problem, but is anyone else encountering this issue or willing to test? I'm on iOS 4.3.5

Ater a few more weeks of testing, I have noticed several more details about the battery. After a full charge to 100%, the first few % (going from 100% down to 90%) takes longer to drain compared to the rest of the battery. So going from 100% down to 99% took me 22 minutes and towards the 90% mark, I noticed more consistent drainage (about 9 minutes for every 1%)
The second thing I noticed is that downloading apps had nothing to do with the battery meter getting stuck. It just took a really long time (about 27 to 30 min) for it to get unstuck after I first woke it from sleep. This would happen only when I left the ipad for long periods of inactivity (sleep). It would not happen after putting it to sleep and waking it up in 10 minutes (battery continues to drain properly).
The third thing I tried to test was to rule out the battery meter reporting the % incorrectly. If the meter was following a pattern whereby it was stuck at 100% for 30 min and then continued to drain properly, this should affect the ipads battery life. I continued to use the ipad over the course of a week (with the meter getting "stuck" several times) until it hit its final 1%. I was able to use it for about 6-7 minutes before it died. Basically the ipads battery meter was reporting the % accurately (even with the meter being "stuck") or the ipad would have just died at around 2% or more since the ipads battery meter was constantly getting "stuck" over the course of the week.
I think this has something to do with the rechargeable batteries themselves. For instance; after heavy usage of the battery followed by a long period of rest, the battery seems to gain some of its charge back or at least retain a higher capacity (this would explain why the battery meter seems stuck when you wake it from a long sleep). However; after heavy usage and a short rest period, the battery seems to not retain this ability.
I'm not sure if this phenomenon applies to all rechargeable batteries and it would be great if other ipad owners would post their experience (not even sure if anyone else actually takes the time to stare at their battery meter and time it for every % that goes down lol).

Battery meter reads only 0-1%, or 99%.
