Battery consumption in power supply operation

Hello there.
i have a Problem with my MacBook Pro 15 i5 using Windows 7 with Bootcamp:
If i start my Mac with Windows 7 ( Power Supply and FULL Battery ) and start play a game ( for 2 or 3 hours ) the Battery is almost empty (Windows Info: "Power Supply Operation - Battery charing - 15% left") after quitting this game. So my Macbook has a Battery consumption during power supply operation. Why my Macbook is using the Battery instead of Power Supply ?
If i use Mac OS i dont have this problem. Just with Windows 7.
Why the Battery is almost empty after playing a game although i used Power Supply ?
Any ideas ?
Thanks

no ideas ? i really need help !

Battery not charging, power supply not reliable

For a week or so I've had trouble recharging the battery in my 12" iBook g4. I had to fiddle with the power supply connection so the computer would recognize that it was plugged in, and the power icon in the top menu bar would flip randomly between running on battery, charging, and plugged in. Often I couldn't fully charge the battery, but it discharged at a normal rate.
Tonight my iBook battery abruptly dropped to reading either 1% or 0%. I tried connecting my usual power supply, which didn't register at all. I tried another power supply and got a few seconds of operation before the computer went to sleep again. So long as it's plugged in it does the same thing whether the battery is in or out.
I'm not sure whether this is a battery problem or a more basic computer problem--the logic board? something else? Any suggestions would be appreciated.

AH, I've basically had the same problem and found a fix! It is most likely a DC-Inboard issue with your iBook as my iBook would boot from the AC Adapter and if it did it would last a mere 20 seconds. The DC-Inboards are old now and die, the part is $10 on eBay, if you want to know for sure its the DC-Inoard plug in the Ac-Adapter and if it turns green you're good (It may be a other issue), it turns a yellow-ish color (Not ORANGE) then it is the DC-Inboard, the orange color can be both good or bad. The yellow-ish color is due to the DC-Inboard not being positive if it charging or not, and when this happens you can "Jiggle" the power cord to get it to boot (However it must stay on a desk and not move!) and if you're lucky you'll have enough time to back up any info you may have (Just for safety incase the DC-Inboard doesnt do the job!)
Here is a link for the DC-Inboard replacement- http://www.ifixit.com/Guide/iBook+G4+12-Inch+1.33+GHz+DC-In+Board+Replacement/69 9

Macbook Battery and/or Power Supply Problem(?)

Hello everybody.
New to these forums but been a Mac user and software developer for many many years.
I've detailed the problem on my blog here: http://vanirsystems.com/danielsblog/?p=209
Basically my battery isn't charging on my Macbook but the power supply is still able to run the laptop - laptop still recognises whether the battery is in/out, have tried all of the usual things:
* leaving it to charge when its off
* leaving the power supply unplugged to get rid of static
* resetting the PSU
Battery has been working fine up until this point, was able to fully charge and run the laptop for hours... then all of a sudden there was nothing.
Battery Model is A1185.
If anyone could get back to me on the forum, or my blog or by email then I would be very thankful.
Many thanks in advance,
Daniel
[ edit ] p.s. really looking forward to trying Mac OS X 10.5 Leopard [/ edit ]

As of yesterday, I am experiencing a similar battery problem. The battery shows up in the menu bar as fully charged, and the battery indicator lights also indicate that the battery is charged.
However, my Macbook shuts off about one second after I unplug the power supply. When I try to turn it on again, it begins to boot up (the disc drive makes it's usual racket!), but before the startup sound would occur, it shuts off completely. The screen powers up but doesn't get to the grey screen before everything shuts down.
But interestingly, the battery will keep the Macbook running if I put it to sleep first. (I can unplug it while it's sleeping without a problem, as long as I plug it in again before I turn it on.)
The battery model is also A1185. I've done the battery update. My Macbook's SN starts with 4H6386N and is from Sept. 2006. Am I eligible for the two-year warranty?
Thanks so much for your help.

PowerbookG4 Runs on Battery But Won't Recognize/Recharge with Power Supply

My 15" 1.67gh Powerbook G4 will run just fine from battery power. The power supply does not charge the battery, though the amber light does turn on when it's connected. The screen power management display acts as if it's unplugged and doesn't recognize the plugged in power supply.
I have another G$ so can recharge the battery, and the power supply cord works fine in that one. I have tried the 5 second reset method (with the power supply and battery out)
This machine was used with an old battery that caused overheating during the summer to the point where the computer turned itself off.
Is the internal power supply fried? Is there a fuse that can be replaced? Is there some kind of other software/firmware procedural fix that I can try?
How much do these cost if I have to have it fixed? Is it worth doing for a computer this old? Can I just buy the part and try to install it? Is there a way to get it properly diagnosed without spending a ton of money?

There are 4 components to the charging circuit: power adapter, DC-in card, battery, and logic board. Unfortunately there is no automated test to determine what is causing any charging issues, so you have to solve it by elimination.
Since you have a working power adapter that will charge the battery on another PowerBook, that's good. And the system runs on battery power alone, so the battery sounds OK. That leaves either the DC-in card or the logic board as suspect. DC-in card would be the less expensive component to change, as they run $75-$95. A replacement logic board can run $300-$400. Those are used parts prices only without labor.
You could take your system to an Apple store, or better yet call them first, to see if they are even still repairing Powerbooks. If yes, see if you can have it sent to the Apple depot for repair (assuming you're in the US). As long as the case isn't banged up, it should run around $350 to have whatever is wrong fixed. If the case is banged up, it can run into the $650 range as they'll replace the case too. Comes back with a 90 day warranty. If they do the repair in the store, the price goes up... a logic board replacement in the store is around $750, as I recall. If you go this route, ensure you have a hard drive backup too before sending it off.

Pavilion DV6 1311el power supply ok, power led does not light up

I own a dv6 notebook model 1311el that works just fine with a charged battery but it wont accept charge from the charger. The led next to the power jack does not light up, i have removed the power button bezel and keyboard and then i used a multimeter to measure the voltage between the wires of the power jack cord and there were 19.5 and 15 volts as it should... I am sure that the power supply works because i gave it to a friend of mine which has the same hp model.

Hello Nessuno,
I see your AC adapter is not charging your HP Pavilion dv6-1311el Entertainment Notebook, your battery indicator LED is not lit. I would like you to start here, this will help you determine if it is the battery or the power supply: Battery Does not Power Notebook or Hold a Charge.
A battery that does not charge might be the result of a power adapter failure, a system board failure, or a battery failure. Please perform the steps listed in the troubleshooting document in order to diagnose the failure.
I hope this is helpful.

New battery not charging and no power supply reported

The battery for my G4 17inch powerbook had expired and a new one was needed. A brand new battery has been purchased and inserted into the machine. With the old battery the charger would go green then quickly amber before going off. With the new battery the light never comes on and in the battery info in the operating system it is listed as a new battery with 1 charge but the power supply section is not listing the power as connected. However with no batterys inserted the power supply will power and run the machine.
Can anyone offer any advise of something I could try or is it likely to be a dead laptop / charging circuit?
Thanks

There's 4 components in the charging circuit: power adapter, DC-in card, battery, and logic board. If you can run on power without the battery, and does not run when you insert a battery, that suggests that the DC-in board may be OK. So ... power adapter works, assume DC-in card works, new battery assume it works ... if you accept those assumptions, then you have a logic board issue.

New battery/power supply problems

i bought my ibook on ebay, put in some upgrades and am pretty happy with it. One thing keeps making me extrememly angry. Randomly, without warning, the power supply cuts out. When I look at the port, the light's still on. This wouldn't be so bad because usually the battery would kick in. However, mine came without a battery. So, everytime my power supply cuts, the computer shuts off. What's the problem?

Mike,Check your Energy Saver options (Apple Menu > System Preferences > Energy Saver > Options Tab > 'Schedule' make sure this isn't set to turn off your iBook.
I'd also try resetting the Power Management Unit. (Click this link and follow the instructions).
At least your clamshell's a good deal lighter! (Doesn't it tip back too easily without the weight under the front?).
The problem with running a machine like this is that the Clamshell has no internal battery (unlike every other Mac ever!) this means that you really do need the main battery for correct operation of the system. You'll be forever re-setting date/time etc so it may be worth inv a main battery - even if it's a really cheap one that only gives you 10 minutes run time - it will guard against this type of problem.

Power Supply Isn't Charging the Battery

This is a rather tricky issue. It's happened before, a few weeks ago, but it had seemed to work itself out and began functioning normally. As I was playing Neverwinter Nights today, the iBook went to sleep. I had the Power Supply plugged in whilst I was playing, assuming that it was charging the iBook. As it was going to sleep, I would try to wake it up only for it to sleep again after a few seconds. I managed to save and exit the game, and I noticed it's at 0%. So I unplug the adaptor and replug it. It continues to go to sleep, so I shut the iBook down.
After a few hours of fiddling with it and checking for information online on my iMac, I managed to get it to charge to about 15%. At this point, I turned the iBook back on and tried to get it to continue charging, but it's slowly been working its way back down to 8% or so ever since.
What's strange is that the 'ring' on the plug lights up as Orange, but it doesn't charge. I've noticed if I leave the iBook and Power Supply plug alone, the charge indicator will sporadically change between 'Battery Life Indicator' to 'Battery Charge Indicator'. It's not like it flickers between the two, but every few seconds or so, it will change from one to the other, but it still steadily drains the battery. I've tried resetting the PMU, but it doesn't seem to have done anything with the situation. I also tried to diagnose if my Power Supply is bad by reading Apple's information pages on it.
One of the troubleshooting documents shows images of bent metal rings on the connector. I looked at mine, and the metal ring is separated at the tip ever so slightly, nowhere near as bad as in the images. I can't figure out what's wrong. Could anybody give me some help?

I have the very same problem - you could try someone else's charger if possible
did not work for me though
If you get any luck could you forward the reply to [email protected]

Power consumption with dual power supply

Hi,
I need to know how dual power supply works, I mean, when you have two power supplies in a router if both of them are working at the same time, or if one of them is working while the other one only begin to work when the first one stops.
And if both of them are working at the same time, what is the power consumption, the same as if only one of them was working?
Thanks

The implementation details can potentially differ per product category but usually the following is applicable:
The product provides configurable power redundancy modes and choosing a mode dictates whether load will be shared across supplies or whether a particular supply will be dedicated for redundancy.
If both (or more) supplies are working at the same time then both share the power load.
The actual power consumption depends on the power required to run the installed components and is the same whether you use power supplies in redundant or power sharing mode.

Can I keep plugging in my iphone to the power supply despite fully charged to reduce the battery cycle?

Since an iphone battery lasts for 300-500 cycles before losing its juice, can I just continuously connect my iphone to the power supply to avoid using the battery, like how I use my macbook.

Yes, you can but best read this

My battery will not charge when plugged in to power supply. What's up??

I recently purchased a new MacBook Pro from my college, and have barely had it two months. One morning I started it up and it would not hold a charge. It will not remain on unless it is plugged into the power supply. If I unplug it while it's on it immediately shuts down.
Sometimes if it's plugged into the power supply for a while it will shut itself down un-announced.
I'm very frustrated, mostly because I just bought it and had Snow Leopard installed and everything. The message on my battery status simply says (Not Charging), though the icon says it's fully charged, and the light on the power supply is green. I'm very confused.
Any idea what's going on and how I can fix it? Is the battery simply not connecting, or is it shot already?

As the original post stated, "One morning I started it up and it would not hold a charge. It will not remain on unless it is plugged into the power supply. If I unplug it while it's on it immediately shuts down."
This is exactly what's happened to mine this morning. Last night everything is fine, remember seeing about 5 hrs remaining on the battery, plug it up but this morning will not remain on unless its plugged in. If I unplug it, it immediately shuts down.
My first thought was somehow I didn't plug it up or there was something wrong with the plug itself and the battery was drained but then I realized its working with the power cord so that's not the problem, only when on the battery.
How can a battery just crap out overnight???

I just got my iPhone 4 a week ago, and I realized that whenever the battery reaches 55% or less, it automatically shuts down. I have to charge it again to turn it on. I won't turn on unless there is an external power supply to it. Why is this so?

I got my iphone 4 a week ago, but i realized that whenever the battery reaches 55% it automatically turns off and will not turn on unless its connected to a power supply (AC charger or USB on pc). I tried hard resetting it but it did not work. Havent restored it. Any idea why is this so? I hope it has nothing to do with the battery.

Hi,
Not that's not normal and is one of the Problems I was having before Restoring as New...
Just make sure you Sync ALL your important Info... Contacts... Music... Etc... to your Computer...
and then do a Restore as New...
i was a bit reluctant at First, because I hadn't done it before... But it was So Easy and am Really Glad I did...

HP DV7-1020US (Power supply/battery issues) Please help diagnose!

Hi everyone,
I've read a lot of forum information about power issues/problems with this model laptop.
But have finally decided to post this question up here for some real HP support.
The problems started with the battery not being able to hold a charge. Shortly after, my brick started making a strange beeping
noise. I purchased a matching brick. I was able to get a few good minutes of charge and then every time after the laptop wouldn't power-up
at all. I'd just get flashing lights on the front (HD, Lightning bolt, Power). The lights would stop blinking after resetting the battery. I did some
research on laptop batteries and found that not allowing it to drain and then be recharged could cause it to go bad.
I purchased and received my new battery in the mail today. I am currently in the process of charging the new battery but have noticed
that the little lightning bolt light in the front of the laptop is NOT lighting up as it should when it's charging.
Is it NOT lighting up because both the battery and brick are after-market products?
I am going to allow the laptop with the new battery and brick to charge for 16 hours without attempting to turn it on.
I'm concerned that the system board or internal power supply might be having problems as well.
Has anyone encountered these type of power issues with this particular laptop?
Should I be able to run the laptop without the battery? That option has not worked for me.
Any assistance/guidance from you pro's out there would be greatly appreciated.
Thanks!
JUST WANTED TO ADD:
Laptop has been charging with new brick and battery for 8 hours straight and now, the battery indicator light is blinking.
I've tried removing the battery and reseating it but as soon as I plug the power back into the laptop the blinking begins again.

Hi people!
I started having the same problem with my 1020us. Battery isn't charging (it's 91% available, when the battery reaches 35% the laptop power-off). The battery led in front panel blinks too when laptop is plugged in to AC adapter).
Another problem with HP. I am so disappointed. =\
