Does ibook draw full power from wall if no battery installed?

I've been using my iBook G3(duel usb) for over a year now without a battery installed(battery died last year). Was wondering if the ibook is now drawing electricity from the wall at 100% all the time now since there's no battery installed. Even when it's asleep or powered down. I heard that if you have a dead battery installed the ibook continually draws 100% power to try to charge it.
thx

If there is no battery in it, it won't be trying to charge it.
It's my opinion that you shouldn't use it without the battery in place. It draws 65 watts at the most (depending upon your adapter). Leaving out the battery subjects the internal contacts to dust and debris. Even a nearly dead battery will usually hold enough power to keep you from losing all your work if you accidentally become disconnected. If Apple intended for it to run without the battery installed, I believe they would have included a battery hatch cover.
I leave my iBook on 24/7 and just sleep the display so the automatic nightly OS X maintenance routines can run. The display takes the most power, and sleeping the display limits the power draw, even if it's trying to charge the battery. It's hard on the adapter to be working at charging a dead battery, though. If you put the battery in and the green ring lights up, you will know that the adapter is NOT trying to charge the battery. Your battery has been out so long that the adapter will probably not try to charge it, anyway. Check it and see. If the ring is green, you'll know it's not drawing a charge.

Cisco 3702i running on a WLC 8500 Drawing low power from 2960s

Hi ..
I keep getting alarm errors in Prime 2.1.
"Access point 'AP01' associated with controller 'WLC-01'
draws low power from Ethernet. Failure reason: 'The AP draws 15.4
watts from Ethernet'.
Prime is running version 2.1
WC is a 8500 running software version 7.6.120.0
2960s is a WS-C2960S-48FPD-L running Version 12.2(55r)SE
I have all ready done the following & still getting the same results :
1)Used the port command "power inline port maximum 30000
2)check & unchecked the box marked pre-standard power
3)Enabled CDP on the AP and PoE+ Switch
4)check & unchecked "Pre-Standard State" and "Power Injector State"
Any help with this would be most appreciated .
Regards
Chris

Could be similar to the below bug, Please the TAC notes at the bottom
AP process CDP packet addressed to bogus multicast address
CSCtc39367
Description
Symptom:
All AP1252s in a given VLAN, which are on switchports configured for extended
PoE (16.8 or 20W), may intermittently see their power draw simultaneously
drop to 15.4W.
At the same time, the APs will each log a message similar to the following:
%CDP_PD-2-POWER_LOW: - INJECTOR_DETECTED_MULTIPLE_MACS_ON_HUB
AIR-LAP1252AG-A-K9 (001e.bead.7c5f)
Conditions:
Another AP in the AP1252's broadcast domain intermittently transmits
a CDP packet to a bogus multicast address (i.e. one other than
0100.0ccc.cccc), such as fdc8.a414.cccc.
Workaround:
On all of the access-ports to which the APs are connected, configure
a mac access-group that filters out non-IPv4 multicasts that are not
addressed to valid multicast MAC addresses.
For example:
Cab4-Cat4507Rc(config)#mac access-list extended WOOF
Cab4-Cat4507Rc(config-ext-macl)#deny any any
Cab4-Cat4507Rc(config-ext-macl)#int gig1/2
Cab4-Cat4507Rc(config-if)#mac access-group WOOF out
(this blocks all non-IPv4 traffic that is not sourced by the switch.)
Further information: So far two TAC cases have been reported to Cisco matching
this bug. In both cases only one Access Point was transmitting these CDP
packets causing all other Access Points to drop the power consumption. In both
cases an RMA was done for the faulty Access Points.
If you require any help in isolating whether you are facing this bug on your
deployment please open a TAC Service Request.

When charging and using, ipad 2 is 100% battery, does ipad use the power from the power adapter or from the battery?

I have a quention, when i am charging and using my ipad 2 at the same time, if the battery of ipad is fully 100%, does ipad use the power to work from the power adapter only or from the battery only or both? Thanks!

YOu don't have to have your receipt. Apple should have a record of how long you've had the device. If you bought it in april 2012, then your 1 year warranty against manufacturer's defects is almost up. You should find your local apple store, make an appointment and take it in.

660 ti does not emit full res from HMDI out.

Alienware X51

MSI GeForce 660TI
Crucial 16gb 1600mhz RAM (2x8)

Vertex III SSD 128gGB
Windows 7 (64)
My 660Ti supports full res through two DVI ports, the DP port, but not HDMI. Through HDMI it only supports 1920*1080. To be frank, my HDMI cable is porting through an HDMI-to-DVI adapter, but this same setup works from my other machine in full resolution.

MY 30G ZEN M VISION DOES NOT CHARGE FULL

My zen is not charging fully it charges maybe 3/4 to 90%, this has been going on for a whole week. I tried different computers, i have checked for updates, i have also used the recovery tool. This incicent happened after my zen battery went completely dead after such a long time ( so actually had to wait for it tobe charged ), now i dont have a fully charged zen. Any suggestions would mean alot

How long have you had the player & is it used alot. If you have a wall charger use it until it stops charging that usually about 3-4 hrs on direct current much longer on the usb. If you can only charge by usb then use a rear port on the computer to charge since you get full power from there front ports are not part of the motherboard the rear ones most likely are. If after that you still don't get a full charge then you will probably need to replace your internal battery in the near future.

Does using a MacBook plugged in ruin it's battery?

I own the 2013 13’’ Retina MacBook Pro. I want to ask 2 questions:
1-When the light on the charger is green, does the laptop still run on it’s internal battery or does it use the power from the charger?
2-Is it good for the health of the battery to use the computer in desktop conditions, always plugged in or does this ruin the battery overtime?

Leaving it plugged in will not ruin the battery, though it is good to unplug periodically and exercise the battery.
The charging circuit has over-charge protection, when you reach 100% the circuit switches to using line power for the MacBook Pro (what is happening when you see the green LED). When the charge drops to 93-95% the circuit starts charging again to top up the battery (the LED is amber then).
Discharging the battery to the point of shutdown is not good for the battery and does nothing in the way of calibrating the battery. Lithium-Ion batteries do not have a memory and cannot be calibrated, no matter what you may hear to the contrary. The only calibration that can be done is to the charge reporting circuit.
Discharging the battery to 50% and recharging will give 3 to 4 times longer battery life than full battery discharge to shutdown, so use the battery half way and recharge to get a battery that will be healthy longer.

HT1338 Does anyone have a fix for the error message "Because a USB device was drawing too much power from your computer one or more of your USB devices have been disabled" - this is a brand new machine with nothing connected to the USB ports - i've done u

Hi
does anyone know how to fix the message on my iMac:
"Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled."
This is a brand new machine and did not have anything attached to the USB ports"
Thanks for any help

If you are getting that message on a brand new Mac with nothing connected to the USB ports, take it back. It is broken.

Which rail(s) does XP CPU draw power from on KT3 Ultra2

I wonder if someone can just clarify the following point for me please. My understanding is that on the KT3 Ultra 2, the processor draws power from the 3.3 & (or) 5v rails and not the 12v rails. Is this correct?
Many thanks for any info that you can provide.

Cheers Wonkanoby, just wanted to make sure. I wanted get a new psu and needed to be clear on what I should be looking for as regards output ratings.

"Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled.

Here is the total error message:
"Because a USB devce was drawing too much power from your computer, one
or more of your USB devices have been disabled.
To prevent damaging your computer, the USB device drawing too much
power has been disabled. Other devices may have also been disabled.
When you disconnect the device drawing too much power, your other USB
devices will be enabled again."
Now in contrast to every other thread on this i get this error message eveytime i connect my soundcard (interface). Not when i start up the mac or anything, just when i connect the sound card. (the soundcard does not have its own power source but note that this has never happened before and i have had this soundcard for about a year!)
It deactivates so i cannot use it.
I have tried:
Connecting the soundcard to my mothers mac -> it worked!
Connecting an external harddrive to my mac -> it worked!
so basically, i can't be the soundcard or the cable and it cannot be the mac USB port?
I don't know what to do! i really need this to work! anyone got an idea??

4th Gen. ipod. No longer charges from wall socket. Still can charge from computer. Wall power adapter and cord both work fine on other devices. Wall Why?

4th Generation ipod. Used to charge fine from wall socket (cord and USB adapter) and could also charge on the computer. Suddenly stopped charging from the wall. The same cord and adapter still work for my iphone, so there is not problem with either of them. What has changed? Why won't the ipod charge from the wall anymore? Is there anything I can do about it?

Thanks! It didn't actually work with the one I was using to charge the computer either. We had tried the computer cable with the power adapter, and it didn't work to charge the ipod, though it does charge my iphone. Following your idea further, I waited for my husband to get home from a trip and tried one of his extra cables he keeps in his backpack. That cable worked in with the USB power adaptor. I had thought that because the cable I use on my computer charges my iphone through the USB power adapter or the computer, and that it charged the ipod through the computer that it was fully functional. Apparantly not. Thanks again.

IPod Nano Drawing Too Much Power From USB Port

My daughter plugged her iPod into the USB port of our iMac today, something she has been doing for months and months, and yet this time she was greeted with an error message telling her that something was drawing too much power from the USB port, so my iMac was shutting down that port. I moved the iPod to another port -- same error message. I moved the iPod to another iMac -- same message. So I am confident that the culprit is the device and not the computer. Any ideas on how to resolve this issue? The iPod is an iPod Nano 7th Generation (current model).

My issue has been solved. The USB cable was bad. I am unsure how to remove my question from the forum ... sorry for taking up anyone's time.

Ibooks battery power from 22 % to 0%

hi all ,
I was looking for this issue if any one has faced it but can't find any. I had an year old Ibook g4 and it was working fine untill some day it was low in battery.
I saw it at a 33 % level at first and within seconds it responded that battery using system safe power or something like that( i dont remember that exactly).
And same happened it today when the power was at 22 % it dropped to zero level in no time .. I have no idea why this happened. My warranty just got over so i am clue less to find any help from them...
Any help would be great.

If you checked to see whether or not your computer's battery was among
those specified serial numbered ones in that Apple listed in their Recall
page, and it was not; perhaps you need to see in System Profiler >
Power in the computer, what the battery cycle count and amp hour life
and other battery-related readouts are in there.
When your computer went to sleep after the menubar battery gauge went
to Zero, did you immediately plug in the power adapter and give the battery
a 6 hour or maybe 8 hour charge; at least until the amber/orange indicator
light on the charging wire had turned green, then wait maybe another half
hour before disconnecting the charger and starting the computer? Could
be you need to run the battery to zero again and then let it go to sleep;
and yet again reattach the power adapter and just let it charge; maybe
even 12 hours to overnight that time, to be sure it really is charged as
full as it will reasonably get. Then look into the System Profiler> Power
section to see what the battery says for original battery Amp/Hr (that'd
be the new capacity) compared to the second amp hour listing shown,
which would be for the battery as it then appears to the System.
A low battery amp hour listing indicate (after all that) the battery may be
going bad. But it may be only the calibration of the battery was needed
and the charge memory and indicator were needing a reset & recharge.
But if your computer's battery is among those recalled, you should stop
using the battery as soon as possible and follow the instructions in the
battery recall information and order page. They say to remove a recalled
battery and run the computer from the AC power adapter until a new
battery arrives. There are additional instructions with replacement batteries.
