Static charge and Mac Pro wake up

Just a curiosity question -
Often, when I am about to sit down at my Mac Pro, I'll reach for my desk chair and receive a tiny static shock - probably from my socks and the carpet. But the goofy part is that it wakes my Mac Pro from its sleep mode. Isn't that strange? Does this happen to anyone else?
I'm not even touching the Mac Pro or the table it is sitting on - I am touching (and shocking) the chair!

One of the USB cables is picking up the electrical
radiation from the spark. Any signal on the USB will
wake the computer.
The funny thing about the stock answers given on this forum to this question is that it's treated as if it were a common, expected occurrence. But after owning 5 Macs and 1 PC over 15 years, I have to say that the only computer I've ever owned that is so sensitive to the local electrical environment is the Mac Pro.
The Mac Pro wakes up for small, normal, everyday electrical disturbances that never affected any other machine I had.
There is something different and possibly defective about this particular model. I do not think it is so easy to brush it off as an expected disturbance to the USB cable, because all my other sleeping computers have USB cables too, and they stay sleeping if I want them to.

Even when I charge my Mac Pro to the full bar, the battery seems to be drained even when I am not using it. Example, after charging it full, i switched it on the next day and its 79% battery left. Is there something wrong? help please

Assuming you are disconnecting from line power, when you say switched on, do you mean it was shutdown or in sleep mode? If sleep mode the battery will still drain because sleep still keeps some things active and the battery does drain a little. However, to go from 100% to 79% charge overnight is a bit excessive in sleep mode. Unless you have some processes set to activate over night by the cron file and do things like backup the system.

1500VA UPS + Sleepy Mac Pro Wakes Up = Overload

I have seen a couple of people mention that upon a "USB event" informing a sleeping Mac Pro that the UPS went on battery that the UPS then went into overload. I also have precisely this same problem for a stock Mac Pro. The discussion I am referencing is:
http://discussions.apple.com/thread.jspa?messageID=3052641
My question is, is this normal? The Mac Pro shouldn't draw in an instant over 1440VA (120V * 12A) for a stock system because there isn't any additional electronics requiring that power. If it WERE a fully loaded, fully connected (external devices included) system, then sure I can understand this. However, the computer shouldn't draw what it doesn't need. I DO understand that there can be spikes in current draw, but more than 1440VA? Is this normal?
Is there anyone who has a UPS and a Mac Pro who has put the Mac Pro to sleep, lost power to the UPS (intentionally by pulling the cord or by accidental power loss), had the Mac Pro wake up WITHOUT overloading the UPS? Even when my Mac Pro is the only device connected to the UPS it will overload the UPS upon wake-up.
To add a stipulation, if the Mac Pro is asleep but there is no communcation link (usually USB) between the Mac Pro and the UPS, then the Mac Pro will sleep happily in ingorance of power loss and thus not try to wake up and overload the UPS. However, if you try to wake up the Mac Pro while the UPS is on battery, then that may not be a good thing.
If anyone CAN put their Mac Pro to sleep while on a UPS and lose power, then what is your UPS's ratings and is your Mac Pro the stock configuration?
Thanks. Just trying to determine what is normal for the Mac Pro. Currently I am NOT putting it to sleep and all is just fine even when my CRT monitor has to wake from sleep (we've had two power outages within the last three days, besides my own intentional power loss tests).

120V * 12A = 1440VA
240V * 6A = 1440VA
Which is close to the 1500VA limit of the UPS;
If the Mac Pro draws more than 1440VA, then it is out
of spec even if it IS just a spike. The power supply
should be covering/dampening spikes. I was told by
AppleCare that the power supply is a 980W supply.
980W is the maximum for the whole system but not
necessarily NEEDED if there are no devices needing
that much power. Apple says 250W for the stock system
at peak performance, but it would be nice to know
what is the peak spike in power draw. If there are
spikes that draw beyond even the power supply's
capability, then shouldn't there be a recall for
those systems?
It would be nice if high powered switching supplies did not have a current spike at turn-on, but they all do.
Some people have mentioned that even their lights
flicker when the Mac Pro (and PowerMac G5) is powered
on or wakes from sleep. Is that also normal?
Normal, but not desired.
One more thing. If an Apple laptop had a peak power
draw spike like my Mac Pro, then the laptop battery
would likely overload as well and shut the system
down immediately (as in power disappears immediately
rather then a nice shutdown process). Can anyone
imagine going to wake up one's laptop only to find
that upon wake-up the laptop overloads the battery
and the system shuts down (that's only possible if
you were able to power up the laptop at all which
means you'd probably have to be connected to a wall
outlet before being able to put the laptop to sleep)?
A laptop runs directly from the DC battery. The input current surge is in the input part of a power supply where the AC is converted to DC. A laptop doesn't have that. Some parts (such as disk drives and firewire ports) use 12 volts directly from the battery, Other parts, such as the backlight and CPU, need higher or lower voltages. These use switching supplies, but since they are running from DC, don't have the large input capacitors and current surges.
The ideal way to handle UPS is to run all the equipment from DC, from a set of batteries. A power supply charges the battery when AC is available. A phone exchange runs that way. Everything is designed to run on 48VDC from a set of batteries in the basement. These are kept charged by AC, or if the AC is off for too long, diesel generators. Some computer companies made 48VDC power supplies as an option for computers they sold to phone companies.
Three-phase AC input would also allow a design without a high start-up current surge, but would severely limit sales for home use.
With high powered AC input switchers, you need a larger than normal UPS, or one that is designed to handle a large start-up current spike. Such an UPS might draw too much power to run on a household circuit.
Mac Pros are getting close to the limit for home use. A dedicated circuit should be used if possible. Apple does not want to stress this, so as not to limit sales.

"Charging" icon when actually not charging on Mac Pro Early 2008

I'm perplexed by a charging/syncing issue I noticed recently with my iPad and Mac Pro Early 2008. I've seen the many posts about the "not charging" message when it is actually being charged. My situation is the opposite - I plugged in the iPad last night for sync and charge with my Mac Pro and when I woke this morning, the charge icon was still on the iPad but the charge level was the same as last night - i.e., 55%. I confirmed the iPad screen was off.
One change from the previous times I've charged is that this time I used a new USB extension cable - might that be the culprit? The cable worked for syncing and an iPad software upgrade. I would think that the iPad would give a message that it is not charging if there wasn't enough juice available. Seems odd to have this opposite phenomenon occurring.
I finally disconnected and plugged the iPad into the 10W wall A/C charger and it now appears to be charging normally.
Thoughts?

I checked the machine settings this morning and while the display was in sleep mode the computer was set to never sleep. I'm also wondering if there's a chance the iPad was "awake" all night with screen on - don't think so, and I kept it plugged in this morning and put the iPad screen to sleep for at least 20-30 minutes and the recharge progress never changed - i.e., stayed at 55%.

Can't Get MacBook Pro and Mac Pro to Network

I have a MacBook Pro (2008 - 2.5 Ghz. Core 2 Duo with 4 Gb of RAM running OS X 10.6.7) that I have been connecting to my Mac Pro (2005 - 2 2.66 Ghz Xeon with 20 Gb of RAM running OS X 10.6.7) through an Ethernet switch on my school's network. This has worked without a hitch for years, but when I upgraded to 10.6.7 recently, the MacBook and Mac Pro fail to network. On the MacBook Pro, the Mac Pro's icon doesn't show in the shared area, and on the Mac Pro, I can see the icon for the MacBook Pro, but when I click on the icon to connect, I get the message that "Connection Failed There was an error connecting to the server (name of my MacBook Pro). Check the server name or IP address, and then try again." I have tried a direct connect using the "Connect to Server" under the Go menu on both machines, using their IP addresses, but no luck. Is there something I need to re-set to get these two to talk again? I have other Macs on the same network that my MacBook and my Mac Pro can see, and both machines can connect to them. They just can't connect to each other.
Thanks in advance for any ideas you might have on how to fix this.

I fixed the problem by re-setting the default values for my VirusBarrier X6 anti-virus program.

Is it OK to use USB 2.0 connection for Glyph external drive and Mac Pro as project drive?

Is it OK to use a USB 2.0 connection for Glyph external drive and Mac Pro as project drive? I was told by Sweetwater tech support to use Firewire, but both the FW400 and FW800 connections crash my audio interface software mixer (Presonus' "Universal Control" software).
Both Firewire connections also create a 10 second hang for each Command-Save that I do.
USB 2.0 for the external drive seems to be working so far, but is there some reason I should be wary of using this as my go-to project drive? In other words, I am imagining that there was probably some definite reason that the tech support guy mentioned not to use it. But maybe not. It's a brand new Glyph. In any event, it's nice to have the 10 second hang eliminated, and I was just looking for some advice, since digging into the Presonus software issue could take some time.

If you have a mac pro, why not stick the external HDD inside via one of your many SATA cables & have it run 9 times faster than your USB?
Or stick a HDD CADDY in your mac pro, so you can slot in a full sized 3TB HDD for recording, and when you are done, pull it out & slip it in an external enclosure if you need to take it places?

Lacie Speakers and Mac Pro Firewire problem waking from sleep and loud feed

Lacie Speakers and Mac Pro Firewire problem waking from sleep and loud feedback. I had a powermac before this with the speakers and it worked fine. But the mac pro is having these issues. Is it the firewire port or the speakers or (and most likely) just a firmware glitch with mac pro? Anyone else see these issues?

http://web.mac.com/jerimydulay/Site/MyAlbums/Pages/Lacie_FirewireMIDI.html
Here is my audio settings. For some reason I wish I could remember what I did. It was actually the Apple Store tech in the Unversity Village in Seattle that gave me the idea and I swear I had to change the settings in MIDI setup. Now that Leopard is out it seems the MIDI stuff has been redone. I included screenshots of my MIDI setup as it is currently to see if you see something different on your computers. Let me know!

SADLY not as i downloaded an upgrad to my original PAGES/
i have in the meantim had to open www.icloud. then from there import the file that i am working on and then check on ipad if it uploaded/ yes it did.
but what a waste of time as it doesn not save any changes done automatically back in the cloud....
i am now downloading the new LION and hope that it will fix the problem
i cant find any other way. I was lead to believe that you wrote, it saved automatically, on to the cloud, you then opened anohter device in anotother country even, and the new file was there, waiting, in its latest version.......
and the same magic was supposed to happen in reverse.
It doesn't/
if i have to open a browser, go to www.icloud....why on earth did they not just leave us an icon to drop it in in that case?
I hope the new lion will help resolve the isssue/
any other ideas> keep em coming...thank you so much.

New to MAC - trying to sync iphone and Mac Pro with imac

Hi,
Just made the switch to Mac. Purchased my Mac Pro yesterday, loaded .Mac, and plugged in my iPhone to the computer. Followed the steps to Sync iCal and contacts from iPhone and although it is registering there is a phone and downloading photos, it is not syncing anything else.
The steps I took were System Preferences, .mac, and checked the relevant boxes. It indicates syncing is taking place but the calendar on iPhone and Mac Pro are not syncing.
Could anyone help with advice? SHould I be able to sync easily between the iPhone and the Mac Pro with .mac?

You use iTunes to sync an iPhone - not *.Mac Sync* or iSync.
*.Mac Sync* is for syncing between Macs, and iSync is for syncing third-party mobile phones and PDAs.
The iPhone specific forums are here:

HT201380 keep having scrolling problems with Maverick on both iMac and Mac Pro despite downloading mail software update

Have scrolling problems with Maverick despite downloading mail update on both IMAC and Mac Pro
Have to reboot and it helps for awhile then stalls again

The Mac OS X 10.4.7 Update introduced connection issues as a result of (according to the documentation) "Mail now supports connecting to mail servers through a SOCKS proxy". This probably has nothing to do with your problem, but it'd be worth going to System Preferences > Network and making sure the SOCKS Proxy is not enabled in the network configuration used to connect to the Internet.
Also, it looks like the crashes you're talking about are actually freezes, i.e. Mail becomes unresponsive rather than quitting unexpectedly. In Mail, open Window > Activity Viewer, and see whether Mail displays there what it's doing when it freezes. Actually, you may be able to avoid having to force quit Mail by canceling whatever it's doing (by clicking on the red stop icon of the activity).
Reinstalling Mail will probably accomplish nothing, but it might be worth reinstalling the Combo Update for the type of machine and the version of Mac OS X you're using (which you would have to do anyway if you wanted to reinstall Mail):
Mac OS X 10.4.7 Combo Update for Intel
Take a look at the following articles for guidelines on how to properly install system updates:
Troubleshooting installation and software updates
Installing software updates
Basically, you should verify/repair the startup disk before installing the update, and no applications should be running while installing it.

Is an adaptor cable available rouse to charge a Mac Pro from an auto, either a power point or usb?

Is an adaptor cable available to charge a Mac Pro from an auto power point or usb?

I'm having a very similar problem.
I've got a 2010 iMac that I've got hooked up to my Pioneer Elite via HDMI cable using the Moshi adapter.
It's been working great for months, but today the audio began dropping out -- a fraction of a second, every six seconds or so.
I installed the latest Snow Leopard update today. Does anyone think there might be a connection?
thx!

Mac Pro wakes up on its own!

I have had my Mac Pro for over two years, but only since maybe two weeks ago have I had this issue. I always put the computer to sleep when I'm not using it, but lately it will wake up "on its own" with the least provocation. The most frequent catalyst is static electricity, when I feel a spark from touching my doorknob, or turning on my lamp, or taking off my sweater, the computer will turn on, even if I'm a few feet away. Plugging the power cable into my nearby MacBook will do it too. And I think, though I can't remember exactly, that it sometimes happens without anything electrical happening nearby, just seemingly at random! Does anyone know if I can do anything about this?

This is for a Mac that won't sleep.
Here is KB article HT1776 with their tips.
Mine follow;
USB devices and hubs often cause Macs to not sleep or wake quickly from sleep (notably HP printers and scanners, HP all in ones, and Cannon scanners). Disconnect all USB except for keyboard and mouse and try. If it sleeps, add one back at a time testing after each one to find the culprit.If you've set your Mac to receive faxes, it may not be able to sleep. It might also have a damaged preferences file.
If you use your Mac for faxing, open System Preferences. click Print & Fax, click the Faxing tab, and uncheck the Receive Faxes On This Computer box.
If that doesn't work or you've never faxed on your Mac, go to Finder/Hard Drive /Library/Preferences/SystemConfiguration and delete the com.apple.PowerManagement.plist and com..apple.AutoWake.plist files (if your Mac asks, type your admin. password).
If the latter file isn't present in the folder, go to user name(probably your name)/Library/Preferences, delete the com.apple.systemuiserver.plist file, and reboot your Mac.
Hope this helps!
P.S. One member here reported this (Michael Gleason);
"I have had this problem with my IMac G5. It is surprisingly irritating. LaCie's Silverkeeper backup software was the cause. By default it gave itself permission to wake up the computer to check if a backup was needed. Do you have this or a similar program installed which has scheduled activities including wake-up permissions as an option?"
Dave Hamilton provided this link, xlr8yourmac.com, to a member, which addresses failure of deep sleep with some users that updated and added new FireWire and USB card.
Also, here is Apple KB article TA2469 about PCI cards and sleep.
tomhorvat adds this; After few days of messing around I found out that I had desktop background (wallpaper) set to change every 1 minute.
After unchecking "Change picture..." in system preferences (under Desktop/Screen saver), my powerbook went to sleep all by itself.
Tristan Currier noticed this; "I have a Canon printer(shared) and my imac would not sleep. I opened up printer/fax in system prefs and noticed it said the printer was in use when it was off. Opened up the printer queue and noticed about 7 pending documents. Deleted them all and now it sleeps.
Check the printer queue!"
Good Luck!  DALE

Time Machine turns itself on after my Mac Pro wakes from sleep (every time)

Hi,
I have a 2009 Mac Pro and it currently has Lion on it (10.7.4), but the problem I am about to explain started when the machine was running Snow Leopard, so it doesn't appear to be an OS-specific issue.
I do not currently use Time Machine, I use Carbon Copy Cloner and some online backup solutions to handle backups. I did use Time Machine for a short time on this machine just after it was introduced, but I didn't end up using it for long and the external drive I used for the backups is no longer in service.
The problem is this:
I have Time Machine off and I have all of my drives (I have 4 drives in my Mac and an external drive) set not to be backed up for good measure. Time Machine will stay off like it should except in one instance. If I put my machine to sleep, when my Mac wakes, Time Machine is instantly turned on and I get a warning telling me no backup drive has been selected and that I should pick one. I go into the Time Machine preferences and turn it off. It will remain off (I've checked the preferences to be sure) until the next time the machine is put to sleep. Time Machine will remain off, even through reboots. It is only waking from sleep that causes this.
I've tried zapping the PRAM, getting rid of the Time Machine preferences and even logging into a new, unused user account and testing it from there and the problem continues. This is really starting to annoy me. I wouldn't mind having TM on, but having to click through the warning every time my Mac wakes from sleep is frustrating.
I don't want to have to buy a new external hard drive and let TM backup to the drive because, as I said, I've got my backup solutions handled already and I'm not willing to put yet more money to use a feature I don't need right now.
I've done searches online and asked around and no one has been able to help me yet. So I thought I'd try here.
Anyone have any ideas?

Do you see a wake reason in Applications>Utilities>Console?

Early 2008 Mac Pro wakes up from sleep with Mavericks.

Ever since I upgraded to OSX Mavericks on Tuesday, my early 2008 Mac Pro keeps waking up from sleep mode every couple hours. It goes back to sleep again on its own though after a minute, so I'm thinking it's some kind of new automated feature that I'm not aware of. With the Mac Pro being fairly loud when it wakes up from sleep mode, it woke me up three times last night! Is there some kind of option in the system preferences that I'm not aware of that can deactivate this new behavior? I usually only shut down my computer once a week, and keep it in sleep mode when I'm not using it most of the time, but I'm going to have to start shutting it down every night now to keep it from waking me up throughout the night...

Hello MARl0,
You may want to disable the Power Nap functionality, if available, in System Preferences -> Energy Saver.
