font color="2200cc" Apple USB Power Supply and Display Flicker /font

When charging my iPod touch using my Apple iPod Mains/USB charger the screen flickers gently throughout the charge. I've tried this on two entirely seperate power supplies (one in Wiltshire, one in Gloucestershire) and both are the same. I don't have immediate access to a different Mains/USB charger to try that though.
There is never any flickering when charging via my iMac and never noticed any issues charging our Nanos on the Apple Mains/USB charger.
Has anyone else noticed this or am I alone?
cheers
mrtotes

I'm living in the US and have the exact same issue. Regardless of the power source and cable (I charge through iMac G5, Macbook, and car charger with three different cables), the same problem is observed. flickering is evident when Safari is loading page when brightness is at the lowest with or without being connected via cable.
However, I sometimes can't replicate the problem when not on cable. I'm trying to find what's causing it but not clear at this point. I talked to Apple support but the guy on the phone couldn't figure out what's causing it and recommended me to go to see genius.
I hope this is a software issue rather than hardware.

Can Shuffle play while charging on Apple USB Power Adapter?

Hi,
We would like to purchase a shuffle (2nd gen) to play continuously music on hold to our company's telephone system. The Phone system's audio-in jack is compatible. I've connected my 1st Gen iPod shuffle to the phone system, and it plays fine.
We will not be able to plug the shuffle into a computer, so we will need to plug it into the Apple USB Power Adapter.
Is anyone doing this? Does it work? Any problems?
Thanks,
David

Equivalent solution: Apple Universal Dock + Griffin DOck Adapter for 2nd Gen Shuffle + USB Power adapter
Just need to remeber to set the switch in either charge or play position...

Macbook Pro power supply and grounding.

Hey Apple people. I noticed something disconcerting with the power supply on my MacBook Pro 13" (non-retina)
I have a stainless steel metal table in my kitchen. It is the same type of stainless steel table you find in restaurants.
I have my 13" MacBook Pro in a Speck See-thru case.
The MacBook Pro in it's case is sitting on a Rain Design "M Stand".
The Rain Design "M Stand" is sitting on the stainless steel table.
I am wearing a short sleeve shirt.
I am sitting on a fabric covered chair at the table.
The battery was getting low so I got out my power supply, which is the power brick with the two prong plug adapter.
I plugged this into a power strip and the other end into the computer.
While touching the case of the computer with one hand and leaning on the stainless steel table with my other bare arm. I felt a vibration through the fingers that were in contact with the MacBook Pro. I knew what was going on, and I got really concerned.
I tried an experiment.
I got out the extension cord that came with the MacBook Pro power supply and I changed out the two prong plug on the power supply for the extension cord. The extension cord has a grounding post.
When I plugged the power supply back into the power strip and connected the power supply to the MacBook Pro. I no longer felt a vibrating sensation when I was in contact with the stainless steel table and the computer.
I have other MacBook Pro power supplies and I always use the grounded extension cable with them, because it is located at my regular workstation area. This stainless steel table is located in my kitchen, and I was eating dinner and watching YouTube videos.
Just thought you would like to all know that when you don't use the grounded cable on your MacBook Pro. you become the ground.
Never using this power supply anywhere again without the grounded cable.
Thank you for your time.
Matthew Sievert

It depends on what you are doing. Yes, the power supply can get hot. This is normal.

Can I charge an iPod Classic 3G with the Apple USB power adapter?

I have just buy an iPod Classic 3G with 15 GB (SN JQ4239GQQQF) from ebay.
I have read that it's posible to sync it with my PC with Windows 7, but, It is not possible
to charge it by usb.
I could charge it with the Apple USB power adapter?
Thanks

With that particular model, only the Firewire cable and connection will provide power to the device. The USB cable is only for syncing.
Using the iPod Dock Connector to FireWire and USB 2.0 Cable
Here is the cable you'll need.

Old Apple USB Power Adapter with new nano

Hi. I have an older Apple USB Power Adapter (model A1102) that I've been using with an Ipod Mini (bought it with the mini a long time ago). I have a new 3G nano on order. Will this power adapter work with the new nano? Or will I be forced to buy a new one?
Output from the adapter is 5V - 1.0A
Thanks

Since I also converted from a Mini to a 3G Nano, I thought I'd give you a couple of pointers; I probably spent a couple of days preparing my existing mp3 library (and that says nothing about videos).
1) Make sure all of your mp3's are NOT marked read-only and load everything you want into the NEW iTunes
2) Work on collecting/saving the NEW things like album covert art and lyrics (I sometimes use the lyrics area to list musicians/personnel)
3) Re-construct your playlists and SAVE everything (iTunes actually writes back to the mp3 files--that's why you don't want them read-only)
4) Only then start messing with videos, because they tend to crash iTunes depending on your hardware, OS, etc. (for example, iTunes doesn't work well with Vista). My best advice for videos is use a 3rd party converter (like Nero Recode) to ensure iPod format compatibility; don't even waste your time with iTunes for anything that isn't a downloaded/purchased item.

Apple USB power Charger

Hi all,
Is the Apple USB power Charger only compatible with USA wall plugs? Does it come with a thing to plug it into UK wall plugs? Would I need to buy anything seperately?

It is a universal power supply
it does not come with the UK adapter (which you can buy in most electronics stores)
there is a travel kit, but if you only need the UK adapter, that would be a bit of overkill (IMHO)

LEOPARD, BATTERIES, POWER SUPPLY and other power issues

Hello ALL!
Happy New Year!
In fact I feel a bit scary last two days. Never had this kind of feeling since LB replaced :-D My scare related to the topics i've read here about batteries and leopard. Later below i will write my questions specific.
I just summarise my problem:
1. With battery installed unplug from mains leads to instant shutdown like it is some desktop.
2. The battery now does not have LED indication at all even in system it comes up as 100 charged and System Profiler reads information from battery.
3. When In unplug the laptop from mains first time, the battery did not give any indication of level of charge before i plug it in mains, after that it started charging and system indicator was trying to calculate remaining time till the end of charge endless...
4. This battery was working fine since 3 years without significant reduction in capacity. Before yesterday it was enough power to watch 2-2.5 hours DVD.
5. Battery seem to be dead. Mind that it was no slow reduction in capacity (keeping charge)
6. I was making calibration with some regularity.
7. While sleep mode with leopard seems battery drains faster even for me seems general operation after upgrade became longer.
So my questions are:
1. Is my battery really dead and needs replacement?
2. If yes, what are the symptoms of normal dying of battery?
3. Regarding all the posts which incline to Leopard as main cause of dying batteries should I run to buy a new one ....
4.... or it is hardware problem which lays in DC in board (heard also about battery board) which was discussed here but nobody directly gave indication that it was real cause of the problem?
5. Is it possible that even the battery will be brand new when i plug it in laptop it will die if it something related to hardware?
Thank you very much even for some smallest but helpful suggestion.
Ivan
PS: I am not in USA and not in any closest distance to Apple Store genius, most of my friends now on MB or MBP or iMac so even have nobody to try battery on exchange or even power adapter.

You didn't answer Illaass question, the newer minis have an internal power supply and should be connected directly to your mains, older ones have an external "brick". Since you mention the internal power supply, I guess your mini is one of the former, 120-240 V mains connected directly to the computer. If so, it should not be a problem using the tv power cord, if you actually have one of the older minis I don't see how you could connect the tv power cord, the contacts are really different.
So, if you have a new mini without power brick between the mains outlet and your computer, there should be no problem using any other mains cord, provided the contacts are the same. These power cords are massmanufactured by several manufacturers according to intnational standards and freely exchangeable.

MDD power supply and fan upgrade kit question.

Hello, Its been a few years since I posted anything here and I'm getting ready to (possibly) trade in my mirror drive door 1GHZ dual processor machine on one of the current imac-s.
I'm not real hopeful that putting much work into my current machine is worth it. Here's why:
1) crazy levels of noise - I wear woodworking hearing protectors when I surf the web. Listening to music on itunes is fine so long as you like a background of low level blow dryer noise!
2) I'm still running OSX version 10.2.8, I have been too cheap to buy the latest OS. I'm tempted to go out and spend the $119 on 10.5 but I only have the original 256mb of ram installed and since the min requirement of ram is 512, I know I'll need to spend an extra ~50$ on a 512mb PC2700 ram chip. My price tag to do a minimal update is rising...
3) I would love to neutralize the noise and install the Apple provided MDD power supply and fan retrofit kit that they sent me at no charge several years ago while I was still under warranty. But I never did because the tech at my local (Dayton Ohio) reseller told me that the kit only addressed high noise levels when rebooting in OS9. So I never bothered. Looking on ebay, I see where power supplies for G4's could fetch 75 or 100$ or so.
In summary, here are my questions.
1) Has anything come along recently to tame MDD G4 fan noise that is easy to install, cost-effective and most of all, something that actually works to decrease the noise?
2) To get the quietest, quickest performance with the current OS 10.5 should I cut my losses now and trade (or sell on ebay) my MDD, sell the new power supply and just purchase a new machine with the OS already installed?
Thanks a bunch in advance for any assistance...
from Bill.

Bill,
Carl has some pretty good points that I'd agree with - trying the replacement PSU and fans should quiet it down somewhat and replacing the stock main fan with a newer, quieter unit will also help. But I'm going to disagree with him on running Leopard on the G4's with a few reservations.
As you might notice from my profile, I'm running Leopard on my dual-867 MDD and find the performance acceptable; perhaps a little slower than Tiger in some respects but it does run well enough within the limitations of the G4's capabilities. The reservation I have about recommending Leopard on a G4 is the graphics card - without Core Image support (which you won't have unless you upgrade the video card) Leopard is going to tax the CPU more and may bog down in some tasks like Quick Look and Cover Flow.
In the end, whether to continue upgrading the G4 is a matter of use and economics. Tiger would be a fine upgrade with minimal cost and squeeze a few more years out of your G4 if you're not requiring software that needs an Intel CPU (like certain iLife '08 apps).

New power supply and sleep light question

I just got my iMac back with a new power supply and logic board installed under the Apple repair extension program. I had diagnosed the problem using the Apple troubleshooting assistant online. When I did this I also reset the SMU (system management unit) per the instructions with the troubleshooting assistant.
My computer is now working correctly but when I run Software Update I am prompted to install the iMac G5 Sleep Light Update version 1.0. I had previously installed version 2.0.0 back in July/05. I don't have the ambient light sensor iMac. I am a little nervous about installing this version or reinstalling the version I alreay have in my utilities. I realize this is a firmware update and cannot be reversed.
Anyone else experience this with 2 different versions of the Sleep Light Update, I don't seem to be able to find any info on the Apple site.
Thanks for any info
Scott

"reinstalling the version I alreay have in my utilities"
Please correct me if I'm wrong, but if you have it in your utilities folder, I believe that means that the installer folder has been downloaded, but the install was not done. I am thinking that once installed, it disappears from the Utilities folder.
I see no reason why you would need to do that firmware update if you don't want it. In the future, if you or someone else wants to do the update, it'll still be available on the Apple website.

Old Apple USB Power Adapter with New Shuffle

I just purchased a shuffle (2nd gen) and was wondering if I can use the Apple USB Power adapter that I use for my ipod (5th gen - the adapter is about two years old) to charge it, or can I only use my computer? The Apple store shows that it's compatible with the newer adapters, so I'm assuming I should be fine, but wanted to make sure.
Also, is there anyway to check on the computer, once the shuffle is docked, how full the charge is or isn't?
Thanks!!

It should work... try it!
Also, is there anyway to check on the computer, once the shuffle is docked, how full the charge is or isn't?
The only indication is the status LED, it's either orange for charging or
green for "charged"...

How do I use LabVIEW to control and vary the voltage on my Agilent Power Supply and simultaneously record temp from 1 DMM and voltage from another DMM?

I am using an Agilent Power Supply to apply a voltage to a
thermistor to heat an Al chassis. I want to use LabVIEW to tell
the power supply to apply 5V for 10 minutes, then step to 7V for 10
minutes, etc. I am completely new to LabVIEW, so any help would be greatly appreciated!
In addition to that, I want to place a type J thermocouple onto the Al
surface and use a Keithley 2000 DMM to monitor the temperature (it has
a built in conversion from V to Temp for type J). I will also be
using another Kelthley 2000 DMM to record the output voltage of a new
uncalibrated thermocouple. I would like to collect the output
voltage for this uncalibrated thermocouple and the temperature reading
from the type J simultaneously. How should I go about doing this
in LabVIEW? I will be using version 6.1. The power supply
and DMMs will be connected to a PC using GPIB.
Again any suggestions would be greatly appreciated- I have no idea
where to begin on such a project. I have taught myself how to
make a basic VI- converting temp in oC to oF, but that is as far
as my knowledge goes.

What you want to do should be fairly straightward and a good way to learn labview.
First off, if you haven't already, I would download the drivers for the Keithley and Agilent instruments. I found the keithley drivers at the link below. You will need to find the labview drivers for the Agilent PS at their website. Drivers are the VI's you will use in your program to control the insturments.

If you open Labview and go to the help menu and click on Labview bookshelf there is alot of information on getting you started coding labview. This should get you started, if you have anymore questions just ask in this same thread and I am sure you will get all the help you need.

Monitoring 3750x and 3560x Redundant Power Supply and Fans

I need help for monitoring the redundant power supply of my switches (3750x and 3560x)
I have configured my snmp on my switches and is able to monitor interfaces, temperature and etc.
The problem is when I am monitoring the redundant power supply and fans.
I am using two Cisco C3KX-PWR-350WAC Modular Power Supply per switch.
The OID I use to monitor the PSU are the following:
Power Supply 1
.1.3.6.1.4.1.9.9.13.1.5.1.3 Instance: 1003
Power Supply 2
.1.3.6.1.4.1.9.9.13.1.5.1.3 Instance: 1004
When I do an SNMP walk, the value is showing (1) which means normal.
When I simulate a power outage on power supply 1 or 2 by unplugging the power source, the value doesn't change and is still (1).
Values: normal(1), warning(2), critical(3), shutdown(4), notPresent(5)
As for the Fans:
When I remove the fan module, I am able to get a notification that the fans are down, but when I plug back the fan module it is now using a different instance.
Below is my config for SNMP:
snmp-server community XXXXXXXXXXXXXX RO
snmp-server location XXXXXX
snmp-server contact XXXXXX
snmp-server chassis-id Cisco3560X
snmp-server enable traps snmp authentication linkdown linkup coldstart warmstart
snmp-server enable traps transceiver all
snmp-server enable traps tty
snmp-server enable traps license
snmp-server enable traps cpu threshold
snmp-server enable traps syslog
snmp-server enable traps vlancreate
snmp-server enable traps vlandelete
snmp-server enable traps port-security
snmp-server enable traps envmon fan shutdown supply temperature status
snmp-server enable traps errdisable
snmp-server enable traps vlan-membership
snmp-server host X.X.X.X version 2c XXXXXXXXXXXXXX
Note: This problem is the same for all of my 3560X switches and 3750X switches. I am not sure if I am monitoring the wrong OID.
Thanks in advance

Hi ,
You are running an old IOS code , definitely you are hitting a BUG .
there is no workaround or I would say unfirtunetely you will not be able to get the correct power supply status via SNMP.
you need to use command line for this.
I mean "show env all "
**** if you want to know the Excat BUG that your code is hitting ,please contact TAC.
Thanks-

Do I have to have an apple USB power adapter to charge the ipod or can i use one for a htc phone?

Must I have an Apple USB power adaptor to charge an ipod or can I use the power adaptor from my htc cell phone?

Read the cell phone user manual to see if the charger can charge an iPod Nano.
FYI the usb power charger (AC) does not have to come from Apple. I purchased mine from Macmall.com

Severe Incompatibility between Mac Pro 2012 power supply and Tripp Lite 2400 watt Line Conditioner [switching transformer].

The Mac Pro will not power on when connected to the Tripp Lite LC2400. The Power Supply makes continuous clicking noises and repeatedly resets the Mac Pro every 3 seconds.
The same Mac Pro connected to an outlet with no Tripp Lite starts up with no problem.

Hi,
I've the same notebook. I've not had any hardlocks so far, but I've not seen so much flash movies yet. Anyway, I just tried closing running youtube-video tab on Kde4 + enabled desktop effects -> Everything's fine.
Anyway, perhaps we can collect some issues and solutions in this thread. Here are problems, that I encounter:
- restart does not work
- errors during boot:

Issued solved:
- in order to make nvidia graphics working you have to disable Optimius in BIOS.
- Battery not recognized -- fixed after recend updates
- grub2 does not work. As soon as grub2 loads, the laptop reboots. -> stick to grub1 -- works now (either I did sth wrong the first time or a new version of grub2 fixes this issue)
- in order to make the touchpad work properly install psmouse-elantech from AUR
update: this is only a half-solution. vertical scrolling on the right edge works but graphical tools which rely on x11-input-synpatics still don't work. However, everything works fine with kernel 3.3. Once this in the main arch repos you won't need psmouse-elantech anymore.
