Multiple power problems...

Alright, so let me start out by saying that I have checked my power settings on my MacBook as well as my house to make sure that the power settings were correct.
My battery picks and chooses when it wants to charge. For a few days I wasn't able to move the laptop, and when I disconnected it, it would lose charge almost instantly and shut down.
The second issue is that my laptop likes to eat chargers. While I have seen announcements about MagSafe adapters becoming warped, I have had two that decided to warp and they both have been factors of heat that my laptop has put off.
That leads me to my next problem. My laptop frequently overheats and I constantly have it on a desk. My case is cracking and that's an entire unrelated problem and I'm at my wits end. I have had 613 cycles of charging on this laptop and I'm beginning to think that the battery just might be shot. I just need to confirm this before I take it to the Apple Store, as that is a bit of a drive for me.

you definitely need a new battery... they do not last forever.
average battery cycles are from 300-500 before you need to replace them.

1130AG Power problem

I have this AP and it has a problem. If I plug in only the power injector with nothing plugged into the network side of the injector, nothing happens. If I plug an ethernet cable from at Linksys POE switch to the network side nothing happens. If I plug an ethernet cable from a Cisco 3560G POE switch to the network side of the power injector it powers fine.
Once the AP is booted, I can pull the cable from the network side of the injector to the Cisco 3650 and the AP will continue to run. Have tried multiple different pwrinj3 and AC adapter combination and nothing works. I know it isn't the power injector that is the problem. Something in the AP is not working correctly.
Once the AP has been running for a while, if I unplug the power injector from the AP it will die, but if I plug it in again in less than 30 seconds the system will boot again just fine. What is it about the 3560G that allows the AP to boot when nothing else will.
Any thoughts?

What if you connect the AP directly to a PoE switch (without power injector). does it work?
Have you eliminated the cables thing? bad cables cause power problems usually. try to eliminate that part.
If all is fine and the AP is not working it could probably be an AP hardware (or maybe software) problem.

MacBook Pro Power Problems.

My MacBook Pro is exhibiting power problems. I am running Yosemite and it seems that the problem may have arisen since I dowloaded this upgrade. When the battery is charged it shows 99% charge and I can use it on battery power. As normal with use the charge gradually reduces, say to 30%. I then switch off using either the on/off button/apple logo, waiting for the dialogue box, " do you want to switch off etc". The next day, I switch on, but the computer will only boot up when the power lead is attached. When the computer comes on, usually as normal, the charge always shows 0%. When it is recharged the whole process repeats itself. Help please.

Hi,
Thanks for responding. My MBP is late 2009 and the battery has never been replaced. When I look at battery condition, it registers as normal, as it does when I do the power checks you suggested. When I plug in the power cord it glows green and within a few seconds it is on amber, until fully charged. I've done the SMC reset. I noticed this morning that after using it last night the battery capacity was 93% and an expected duration of about 5.5 hours was listed. After limited use this morning, restricted to email admin only, the charge level had dropped to 88%, but the predicted duration was only 2.75 hours. Currently the level is 73% and the duration is 3 hours, although I have accessed the web several times. Presumably there is some sort of algorithm that looks at current usage and predicts the duration. I will continue to monitor this to see what happens. In the meantime if you have any more thoughts!!!
Regards
Roger

Hard Disk or Power Problem

I have a Powerbook that I have had for many years now. Recently it hasn't been booting up. I hit the start button and it chimes like it usually does but the screen and hard disk don't do anything. Sometimes it does boot up but it doesn't start easily. When it does boot sometime freezes when I go through the login and when loading the desktop but once the desktop is loaded it works fine until it goes to sleep. I just bought a new battery for it this summer. I have been reading though the Discussions and I figure my computer is either having power problems when starting up or I need a new hard disk. Any thoughts?

You will find step by step directions at iFixit. Note that your computer does not have the EMI finger referred to in the directions. Also, be especially careful with the tiny screws in the sides on the computer. You don't want to strip the heads or it will be very difficult to get them out. Here are few tips you may find helpful:
• Print out the ifixit directions as well as the screw guide ahead of time.
• Be sure you have the right tools. You don't want to damage the screw heads or you may never get them out. And the Torx screw driver is critical. For a spudge I use the handle of an old toothbrush (choose one made of hard plastic), cut off the brush and beveled the handle end like a flat blade screw driver). For some spudge jobs a credit card will do the trick.
• Click on the pages of each step which involved removing screws to enlarge, then print out the pages. Poke holes in the paper where the screws were removed, poke the screws in the holes and stack the pages in order in which there were removed. Reassembling is a lot easier. No cups to tip over and spill. No guessing. Each screw is exactly in the right place. You can use an ice cube tray, egg carton, dixie cups etc. I previously used small medicine cups one for the screws in each step. I nested them so that the last ones out and the first to go back in are on top. (Some users report cutting up the screw guide and placing the applicable section in each container.)
• Be very careful pulling out leads. Hold the lead as close to the plug as possible and wiggle (the plug ) to loosen its grip. Don’t hold the wires and pull as that can damage the cable, or worse, in some instances pull the wires out of the plug. Indeed, some users have pulled the socket off the logic board! Use needle nose pliers or tweezers if you can access the plug, or nudge the plug with a small instrument to help loosen its grip.
• Use force gently in removing parts. Separating upper and lower case takes some doing. Use a plastic tool (spudge) so as not to leave marks.
• Refer to the screw guide when reassembling computer. Putting longer screws in the wrong place can perforate the circuit board.
So will I be able to put the OS and everything on by the installation discs?
Yes you will. Indeed you may be able to clone the contents of your current HDD to the new HDD by placing the drive in a firewire enclosure and formatting and cloning the new drive before installing it in the computer. If you have data you need to backup and have a sound installation on your current HDD this might be an option to consider.
When you get your new HDD it will need to be formatted before you can install the OS on it. If you need directions for formatting and installation, I can post step by step directions here for you. Let me know.
Good luck.

Intermittent power problem Canon 5D Mark iii

My Canon 5D Mark iii (2 years old) has an intermittent power problem, as described below. It may simply be a question of cleaning the terminals that the battery connects to. I haven’t tried since I can’t reach them at the bottom of the battery compartment.
Details as follows:
this is a recent problem in the last 3 weeks
the problem occurs with all three Canon batteries that I use
from time to time when the power is on, the camera suddenly loses all power and displays an “empty” battery image
sometimes it happens of its own accord while no demand is being placed on the camera
but more usually it occurs at the moment of focusing (I use back focus on the * button)
it is often fixed by turning the power off and then on again. This fixes it half the time
it is always fixed by turning the power off, removing and then re-inserting the battery
needless to say this is very annoying!
Since coming back from a trip, while transferring images from the camera to my computer, I noticed that the (almost) full battery started showing “empty”.
The transfer was completed successfully, and when the camera was disconnected from the computer, the battery showed that it had lots of charge left. Very puzzling!

It sounds like either the battery terminals aren't getting a solid contact or there's a fault (something loose or grounding out) inside the camera. But if something were genuinely loose or grounding out inside the camera, then power cycling or even re-inserting batteries would probably not fix it -- which makes me suspect it's still something outside the camera.
Are any of the batteries new, or are they all about the same age as the camera?
Batteries only last a few years but it'll depend on how they were used. In other words if all three were used about the same and enough charge cycles to be at the end of their reliable life... it might be time to replace them.
It's difficult for the internal battery terminals to get dirty unless the battery itself had something on the battery iteself when you inserted it. You can try a bit of denatured alcohol on a cotton swap to reach in and clean the terminals. Also, inspect the batteries to make sure they're all clean.

Multiple Inheritance problem persists in Interfaces

Hi,
I tentatively made a program and found that multiple inheritance problem of C++ persists even with interfaces. Although this is definetely a special case but I want to know what is this problem known as( i know that this is perhaps known as diamond problem in C++). And is there a way out of this thing.
interface one
     int i=10;
interface two
     int i=20;
interface z extends one,two
public class xyz implements z
     public static void main(String [] a)
     System.out.println(i);
}O/P
D:\Education\Java\JavaStudyRoom\Applets>javac xyz.java
xyz.java:16: reference to i is ambiguous, both variable i in one and variable i
in two match
System.out.println(i);
*^*
*1 error*
Thanks for replying

This is not the so called diamond inheritance problem. What you have here is an ordinary name clash. And as has been noted you can resolve it by qualifying which constant you're referring to, like
System.out.println(one.i);
For the diamond inheritance problem to apply both the one and the two interfaces would need to inherit a common ancestor (that's how the diamond is formed). Furthermore the common anscestor would need to carry implementation which would then be inherited two ways, once via one and once via two. This is the diamond inheritance problem Java is avoiding by allowing single inheritance of implementation only.
P.S. My previous post was posted my mistake.

SP10 - multiple approver problem with CUP

We have SP10 (patch 1) in our development system and cannot move forward to production because of a real show stopper. I have currently reported this to SAP thru an OSS message (and it is in development) but would like to know if anyone else is having this issue with SP10. (this happened even before applying patch 1)
We have multiple approvers when creating NEW users or CHANGING users in CUP. We have it configured to allow just one of the approvers to approve before going on to the next stage. Since we put in SP10, CUP is requiring ALL approvers to approve the request before going on to the next stage. We get the following message when one of the approvers approve the request: Request no: 5020. is approved, pending for other Approvers.
I've seen this reported for UAR and SOD but not for CUP. In fact, there is a fix for UAR in Patch 1 of SP10. I applied this patch but it hasn't fixed the CUP issue. I also don't have the issue when rejecting a CUP request, or when approving it through the configuration --> Request --> Administration screen (what I consider the Back-door since only security administrators get the configuration area).
Thanks for your input.
Peggy

Christian,
I totally agree with you.
The good news is.... We installed SP11.1 and the multiple approver problem is fixed.
We have decided to leave our production system at SP8 until this system settles down a bit. Of course, this means we can't use many of the new fixes and features (such as UAR). We use our sandbox system to apply new support packs and do very rigorous testing. And our DEV system is at SP8 too.
Good Luck.
Peggy

Mini Power Problem

My mini (2009, Intel core2 duo, Snow Leopard, up to date) has a power problem. Perhaps it has overheated.
It shut down unexpectedly, without warning.
I try to start it by pressing the power button. The power light turns on briefly. there is no chime. Then the light goes out.
I tried resetting the SMC. No effect. I tried holding the power button in. The light stayed on for several seconds, then flashed rapidly 10 times, and turned off.
I have given it over half an hour to cool, and placed a fan behind it to help.
No change.
Thoughts?
Other minor points. I upgraded the RAM and hard disk 6 months ago. No problem.
It is running dual monitors, Wireless is turned off, ethernet is on, and I have a speaker plugged through the firewire port. But I tried disconnecting everything and restarting naked. No help.
I'll try again now... nope. Please advise.

Next bit of data. The chime does not happen. That seems to have been a single occurrence. I've opened the mini, and see the internal green LED on the motherboard is lit. When I hit the power button, then may be a tiny whirr. I'm not sure whether it is the disk or a fan. But it lasts a fraction of a second, then the main external power light goes out, and the motherboard green light also goes off, then comes back on. I'm thinking there may be a big power draw (disk drive? Fan?) exceeding the power available, and it shuts off. Possible?

NX6800 Ultra T2D256 Power problem...

I have read all threads I can find on the NX6800 Ultra T2D256 but can't find the solution. I keep getting the "power down because not enough power" error at the start up of XP Home. With the Thermaltake Purepower 560w ps, I'd think it is more than enough to power this card. I have installed the card in my son's computer and he get's the same msg. I have made sure the pins are tight and making contact, it's set up on one rail, and I have tried every combonation I can think of. I called Thermaltake and they say it should run the card fine so they are sending me a replacment ps. For some reason I just don't feel the replacment will do it. Could it be the card? Or is it the slow AMD 2100 CPU? I don't what that would have to do with the power problem of the video card though... I'm pritty sure everting is up to date but I could have missed something...
Any suggestions would be appreciated...
Oooops... no sig line...
Avalanche
A7V600-X mobo
OCZ 512 x 2 duel channel mem
AMD XP2100 CPU
T-take ps 560w (Silent Purepower)

Ok, I will try the 2 power cables again and I take it that nothing else but the card should be run on those 2 lines?
Also, that leaves me with only 2 power lines to run 2 cd/cdr, 2 HD's, and 1 floppy. I also have 5 case fans.
Now can you point me to an explination of what "replacing all the AGP/Gart drivers and doing a driver clean on the NVidia drivers" is?
I am running the ATI 850Pro on that computer right now so I know to un-install the ATI drivers of course before installng the NVidia card. I have never heard of "Gart" and didn't know there were seperate AGP drivers from the mother board drivers...
Still got a lot to learn and thank you for all your help...

L430 multiple driver problems (ultranav and others)

Hello,
I have multiple driver problems with my newly purchased L430.
1) After hibernate the UltraNav driver randomly stops working. This means that the settings are grayed out and my old settings aren't applied. Sometimes the mouse pad and track ball also stop working after hibernate.
2) The hardware mute button and hibernate don't like each other as well. After resuming from hibernate with the mute button on the sound doesn't work anymore. Rebooting only helps if you have disabled the mute before rebooting.
3) The intel usb 3.0 driver can't be installed unless you want a lot of bluescreens.
I do have the newest drivers and BIOS (2.54).

It's ok my friend, I just hope I will be able to help.
Now to the problem. The thing that worries me the most and the reason I asked you to contact a Lenovo Repair Center, is the blue screens with the Intel Usb 3.0 installation. If the driver is correct this should not happen and most of the times it signifies a pure hardware problem, not a software one. Really, it just should not happen, period!
So please, before anything else, download and boot with a Linux Live cd, any distro you like (e.g. Linux Mint, Fedora, etc). Better choose a 64bit version. It's one way of determining if you're facing a hardware problem with the usb 3.0 ports.
The information you give is very useful and more or less complete, but I would like to also know the model of your SSDs, both the 2.5'' and msata.
Meanwhile, you can check either with the Linux Live cd or with Memtest86+ your ram. This does not seem to be a memory problem but it would be nice if we could exclude it from the suspects list. Many - if not most - of these problems are multifactorial and we cannot leave anything to chance..

Brightside with manufacturer power problems

Verizon needs to step up and make this right.
I am on my third Samsung Brightside. All three have had some sort of power problem. The first would auto restart after I powered it down. The second would shutdown when I slide it open. This new one shuts down for no apparent reason. Obviously, many others are having the same issue per the discussion board. Verizon said there is nothing I can do, but continue to return these for replacement. This is not acceptable.
Each device was replaced with a refurb. The 2nd return (a refurb) was used for less than a week before it started powering down upon slide open. Verizon tried to charge me for the replacement due to errosion. I argued that there is no reasonable argument Verizon could make to charge me as I had the insurance. Although the agent agreed to remove the charge, this was sneaky and underhanded. I am very disappointed in Verizon.
I am still using the third Brightside which shuts down for no apparent reason. Is there any way to get a different phone without being penalized?
Message was edited by: Steven Sulkin

this has to do with the power button's position on the phone. when you move your body might hit the power button (kind of like a butt dial). The only way for you not to hit the power button is to have a hard covering on the power button or get a flip phone where the power button is being covered. for the shutdown on the slide the power button is sticking down when you slide the phone. Hold down the power button when you open it and it will shut down.

Notebook gx700 - power problems

I am a happy owner of a GX700,
The laptop worked fine for several years.
Unfortunately for some months now I have problems with booting.
Believing it was a disk problem I proceeded to replace it but the problem remains.
The problem occurs only at the first turn.
Once the machine has booted I can turn the notebook all the time without problems.
looks like a power problem on the motherboard. could it be?
Thx
Pinos69

Were you able to find out the problem? From what I can see it could be the processor, motherboard or it could be something as simple as the power adapter not supplying the necessary power or amperage any more.

Wake / Power problems

I love my MacBook... However, I have been having the same problems regarding Sleep / Power management etc. I searched support but have seen no updated in the KB.
1. Wake -- Several time my MB has not wake from sleep regardless of what I do. Sometimes it will not turn on at all.
2. I have shut the MB down only to come back and find a buring hot MB that is neither sleeping nor Off.
3. I have reset the PMU, no change.
4, Sometimes I need to remove the battery and reinstall in order to start it.
Power problems seem to be complicdted issues with the units
Any other suggestions would be great

I've been toying with this issue and I found that if my Bluetooth mouse gets moved before I open the lid then my MacBook is already waiting at the password prompt. If I then go and enter my password it goes back to sleep. I've got to be careful not to move the mouse otherwise it wakes the machine while the lid is still closed. But if I turn off the bluetooth wakeup then the mouse will not keep the MacBook from going to sleep while I'm using it.
