PCLK2 not in HiZ on PC power up

I am using the PCI-DIO-32HS, and in the 653x user manual it states that this card should power up with all lines in high impedance (HiZ). However, this is not 100% true as PCLK2 outputs 5V when my PC boots up (all other lines seem to be fine). Is this due to the card being damaged, or have I inadvertently changed the power-up setting of my device? If so, how can I change it back.
I base my reasoning on a previous post which seemed to suggest this possibilty, i.e. changing the power-up state of a device. Is this at all possible?
Thanks for the help

Adrian,
You are correct in that all of the lines should be in the high impedance state upon power up. By default, all lines should be pulled down. The way you change that is to connect either the DPULL (for data lines) or CPULL (for control lines) to 5V to pull up or GND to pull down. This is explained in Appendix D of the 653x user manual. If you are measuring 5V on PCLK2, try jumpering CPULL to GND and see if that forces PCLK2 to 0V.

MacBook Pro does not go to sleep when power cord is connected

Hi Experts,
I have recently discovered that my MacBook Pro (2009) with OSX Lion does not go to sleep when the power cord is connected. It does not matter if I close the lid or select sleep from the Apple menu. All that happens is that the screen is powered off, the SIL is solid and I can hear the HDD/fan. I have not changed any of my power settings recently and it has not been a problem previously. If I disconnect the power cord the MB goes to sleep as supposed to (the SIL led starts flashing).
Doing some research I have found other users with somewhat the same issues when VMWare Fusion is installed. I have done some further testing and it seems that if I disable the virtual machine's Network Adapter and quit VMWare Fusion the MB goes into sleeping mode when the lid is closed even with the power cord connected. Enabling the Network Adapter again prevents the MB to go into sleeping mode when the power cord is connected. This even applies when the VMWare application is shutted down.
My guess is that the Network Adapter somehow prevents the MB to go into sleeping mode. The workaround is of course toggling the Network Adapter on and off but the virtual machine has to be running in order to do so. Not being that familiar with network settings on a Mac is there any other way to get around the problem?
Thanks in advance :-)

To anyone,
I have turned internet sharing off but the Ethernet box remains checked. If I uncheck the Ethernet box, the Internet Sharing bubble turns red, however when I close System Preferences and re-open, the box is automatically checked although Internet Sharing is off. Because of this my Macbook Pro will not sleep properly.
All other sharing items are turned off. Only Internet Sharing continues to automatically show Ethernet as active from a Wi-Fi connection.
Any advice?

Replacing Firefox 3.6.16 containing my history, bookmarks etc by version 4.0, I find that it will not open on my Mac Power PC G4 running on OS 10.4.11. Is there is a compatibility problem and how do I retrieve version 3.6 with my bookmarks etc

Firefox 4 requires at least OS X 10.5 and an Intel Mac. There is a third party version of Firefox 4 that runs on OS X 10.4/10.5 and PPC Macs, for details see http://www.floodgap.com/software/tenfourfox
If you prefer, you can get the latest version of Firefox 3.6 from http://www.mozilla.com/en-US/firefox/all-older.html
When you install one of the above it will use your existing bookmarks etc

I have tried with a wired USB keyboard and mouse using a single screen. Powered up with option pressed. No change.

Run the Apple hardware test to see what it tells you. Run the extended test when prompted, which can take awhile.

IPhone 4 will not charge when connected to power

I have tried the home/ power trick and at first it went to the apple logo then would power up and then cycle off and then repeat infinitely. Now the phone is so low on power that it only shows either the lightening bolt while connected or the cord + lightening bolt when not connected to power. It is still not charging though. I left plugged in overnight and still no change.Help please

If not a problem with the power adaptor or cable being used, more than likely the iPhone has a hardware problem with the battery or something else. Make an appointment at an Apple store if there is one nearby.

Try booting in Safe Mode by holding your Shift key down when booting. Also, try holding the eject key down when booting to eject the DVD. If you plug a mouse in and hold the clicker down when booting, that should eject the DVD.

Can not edit or create new power points since installing Yosemite.

I can not edit or create new power points since installing Yosemite. I can open and run the power points I have previously created but every time I try and edit or create a new power point it simple comes up with this
Also when I open the font drop down menu all the font names are in Chinese

Have you run all the office updates? We have to assume this is a proper copy of Office 11 of course and not one 'from Hxxx-Kxxx'. I would also consider re-installing Yosemite-something is screwy on your installation of something if its picking up China..unless of course it is true that the Chinese have been hacking into iTunes and are secretly trying to make you into an agent of the state..you will speak Mandarin..you will speak Mandarin

"iPad not charging Connect to a power adapter or a USB port on this mac to charge" Maverick issue!

Ever since we updated to mavericks our deployment of 60 iPad's flashes "iPad not charging Connect to a power adapter or a USB port on this mac to charge" on the screen every time one is plugged in. It is a false alarm because the iPad does in fact trickle charge and it does update the device like it is supposed to. At this point it's more of an annoyance then an actual problem. However I would like it to stop popping up every time one is plugged in.
Does anybody have any ideas to stop it?

Your computer USB port typically provides only 2.5W of power. iPads require 10-12W of charging power. That's why you get the "Not Charging" message. However, the iPad is charging, but much slower. There's no way to stop it.
 Cheers, Tom

HP Pavilion dv6-1355dx not turning on using AC power supply.

1. Product Name and Number:
VM222UA#ABA "HP Pavilion dv6-1355dx"
2. Operating System installed (if applicable):
Windows 7 64bit
3. Error message (if any):
Dose not turn-on on AC power or charge the battery
4. Any changes made to your system before the issue occurred:
None
Summary of the poroblem:
Facts:
1) The laptop works perfectly fine using the battery.
2) The battery dose not charge using the AC adapter that came with the laptop.
3) The battery dose not charge when the laptop is turned on or off.
4) No chaging light turns on when pluged into AC.
5) When the battery is pluged into the battery slot on the laptop, the white AC power led on the dc jack turns off.
6)The very second I remove the battery from the computer, the white AC power led on the dc jack turns back on!
7) With the battery removed and the AC power supply pluged into the laptop, the laptop won't turn on, and the white AC power led on the dc jack remains on.
Tests done:
1) Used another adapter with the laptop, but had the same problem.
2) Used different battery, but had the same problem.
Interesting fact:
When the battery is completly drained out, the white AC power led on the dc jack turns on, but I still cannot turn on the laptop on AC power supply.
Note:
I Have a multimeter that I want to use to test the power supply and charging circuit on the motherboard, but I don't have a schamatics of the mother board, so I am stuck.
Any suggestions from the HP community would be appriciated. Thanks.

The laptop has a modular DC jack that plugs into the motherboard with a cable and does not require soldering. The first thing to try is a replacement of that jack. Here is the Service Manual:

Try this...
Press and Hold the Sleep/Wake Button and the Home Button at the Same Time...
Wait for the Apple logo to Appear and then Disappear...
Usually takes about 15 - 20 Seconds... ( But can take Longer...)
Release the Buttons...

PCI-GPIB does not like returning from computer power-save mode. I need to restart the application. Uggh! Customer not happy.

It seems volatile memory is lost on the PCI GPIB Card. When the system returns from power-save, I cannot get to my GPIB instruments. I have to close the application and restart it. I've tried unregistering and reregistering the gpib globals and resetting the device interfaces (reissuing the ibdev command) without luck. I am using Visual Basic 6, but I also get the Measurement and Automation Explorer to fail in the same way, so I don't think it is my development environment.

Can you change your power save settings? What operating system
are you running?
Also, some BIOS's have options for power save. For example, recent
IBM's can be set to maintain power to all peripherals, or only to main
memory. Of course, you would want it to maintain power.
I suspect the GPIB board and its driver are completely unable to
handle power save operation. It probably was never considered while
it was being designed.

Because of low battery my iphone 5 got switched off and than its not starting by pressing the power button or by keeping it on charge. While charging a white screen comes for 2 second and goes away. This process continues till the phone is on charge. Please suggest how can I start my phone.

Hello Ritugor,
I would be concerned too if my iPhone was not powering on. I found an article with steps you can take when you encounter an issue like this. I recommend following the steps below:
Will not turn on, will not turn on unless connected to power, or unexpected power off
Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIsand corrosion.
Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
After at least 30 minutes, if:
The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
If the display turns on, go to step 4.
If the display remains black, go to next step.
Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.

Thanks Niel. Can you tell me how to learn whether my DVD is Mac OS X server 10.5 or 10.6?
That info is not in Info. The disk was created Aug 2004, so it seems very unlikely.
I guess I have to ask Yamaha for an upgrade/replacement. It has not been easy to reach Yamaha support. Suggestions welcome -
