Carbon X1, OneLink and non-working USB ports

I have a Carbon X1 (2014) and the ThinkPad OneLink Dock (4X10A06077). I have Windows 7 Pro installed. Sometimes when the system returns from sleep the OneLink taskbar icon displays "Detached!". Even though the icon says Detached!, the display attached to the dock is working, but the USB ports do not function. I lose mouse and keyboard; unplugging/plugging does not work. USB ports on the Carbon X1 do work. I have not verified whether or not Ethernet also fails as I am using WIFI at this time. The USB ports on the dock continue to not work after restarting the laptop. Power cable needs to be unplugged from the dock before the USB ports work again. I have updated all drivers. The BIOS is up to date. I've disabled all power management on the USB ports in the Windows Device Manager. However, the problem persists. Thanks

Welcome to the forums. Lots of good information and help to be had here.
OK, first, let us know more specifically which of five flavors of Power Mac G5 you have. Find the serial number on the build plate on the inner bottom panel just below the CPUs and use this site to get the exact configuration:

In the meantime, assuming that you haven't replaced the PRAM battery in quite a while or ever, that would be a good thing to do.
Getting dust out of the system is a must. The power supply is especially prone to dust buildup. You might want to deal with that by taking the machine outside, as it can get pretty thick coming out.

I have an hp pavilion laptop with non working usb ports

I just called HP to order a replacement OS cd so I can restore this computer -- I've tried everything else to no avail! I was just told by the hp technician that an HP laptop that is not yet 5 years old that I paid nearly $800 for is GARBAGE! He actually indicated I should throw it away!!
I have no words to sufficiently express my disappointment. I will never buy another HP product.

The DV6000 series was very prone to motherboard failures of all kinds, it might be time for an upgrade.
Or you might consider sending it in for repairs

I plugged in my ipod and now i get 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" - i have a MAcBook pro and now my USB ports do not work - can anyone help me ???

Sometimes you have to reset the SMC two or three times for it to work, don't know why. I've seen that error message before and 100% of the time it was fixed with an SMC reset. I suppose it's possible that your keyboard or mouse IS drawing too much power, do you have access to another you could try?

Solution and problem about USB port shutdown in thunderbolt

Problem:
Recently, i find that all USB port, audio in my thunderbolt have been disabled and when i restart computer, it will work for a while, i play a song, the audio go through display for a while, then go to Internal Speakers. In System Preferences -> Sound -> Output, i find that Display Audio disappeared. i googled online, i find that USB ports are disable as same time. I went to Apple Store, changed logical board, it DOES'T work. I called them, THEY DO NOT KNOW WHAT HAPPENED.
What i do:
To my knowledge, the thunderbolt display connect to my Macmini by thunderbolt port, the OS recognize thunderbolt as two logical ports, one is video and another is USB ports(just like usb hub). the audio is belong to USB ports. Therefore, i guess that the problem is software, not hardware.
Solution:
If you have this prolbem, please do not apply any update after 4 april 2012, the files include Java update for OS X 2012-001 to 003, also a flash play update( it is maybe the flashback virus). I am not sure which one cause the problem. Because my work, i have to use time machine every half day to backup my computer, so i restore my OS and find the solution.
I hope it help you.
Readman

For most users I don't agree with the above recommendation. The latest Java updates address the security holes being utilized by the current strains for the flashback trojan and also attempt to remove it if you are infected. So here's yiour choices:
1. Must you have sound coming out of your display's not-so-good speakers vs. alternative better sound systems? If so take your chances, or,
2. Install the updates to at least check for the trojans (or at least use F_Secure's Flashback Removal Tool) but turn Java off. Turning Java off is the general recommandation anyhow, no matter whether you update or not.
3. If you must use Java, and don't update it, risk the possibility of getting one of the flashback trojans and possibility compromising your on-line security. Here too turn Java off in at least the browsers you use.

Whenever I go to iTunes with my iPod 5th generation 32 gb iPod Touch, running iOS 8.0.2, It tells me that the "Other" category is using up 14.59 gb of data. I have no clue why it says this and I have searched the internet for fixes and none worked.

Whenever I go to iTunes with my iPod 5th generation 32 gb iPod Touch, running iOS 8.0.2, It tells me that the "Other" category is using up 14.59 gb of data. I have no clue why it says this and I have searched the internet for fixes and none worked. I have tried on a windows and a mac and noticed no change. I have tried restoring to a backup but that didn't help. I haven't had time to do a full restore but I will try if the problem persists.

An "other" larger than about 1 1/2 GB indicates corrupted files.

Next, usually restoring from backup eliminated the corrupted files. However, sometimes restoring to factory settings/new iPod is required.

I have an Iphone 5S and used to sync it to my computer in the past without any problem, but now I can't and appears the message "usb device not recognized", and the cable is good and so the USB port. Do you have any idea what's the problem?

Try leaving it plugged in and then restart the computer.

Completely frustrated with downloan not working and deleting and attempting to reinstall resulting in three different accounts on my computer and none working.

I downloaded Firefox mobile to my Droid. Connected to computer and followed instructions, using code provided on phone. Did not work. I tried to re-sync phone. It didn't work. I deleted Firefox on phone and reinstalled app. The connected phone to computer to re-sync. Could not get anything to work using"I have an account" tab so opened up another sync account. It didn't work. I deleted app again and tried again and used a third sync account to sync phone with computer. I got nowhere. Completely frustrated with three sync accounts and none working.
Need help to delete all accounts and start over. Can't seem to find a way to do this.
Thanks in advance.

Colin,
I tried this (opening in Photoshop CS5 and resaving as jpg) as you mention:
The remedy to this problem has usually been to open the image (the one that is having an identity crisis) in Photoshop or another image editor, and simply resave it. You don't need to edit it or rename it or anything--just open and resave.
Re-imported and it does work fix (I get picture1 and picture2 instead of just picture1 for all pictures).
Having said that, I looked at all the file properties I could for:
picture1.jpg (original)
picture1.jpg (resaved in CS5)
To see what changed. All are properties are identical (color depth, pixel size, etc.) except that resaved image is ~20% larger (I saved max file size jpg in CS5).
So original is ~6MB
resaved jpg is ~8MB
So the question - why can't CS5 premiere import these directly (with resaving?) and what is working with the resave that locks up the first time?
These pictures are straight from a Canon 50D, with no editing or resaving - dumped off camera to computer. I can reproduce this error 100% of the time (new project, new folder, import 2 pics) so it isn't something goofy with the way I'm importing - 100% how premiere is handling this.
Very disappointed that I now need to open/resave/rerender each of ~1100 images to simply use them. Given that these jpgs are being produced by a mainstream camera with support image format.
Any thoughts?

Calculate Date/Time Difference in a Calculated Column Omitting Weekends, Holidays and Non-Working Hours

I am looking for a formula to use in a calculated column that calculates the difference between two date/time fields while excluding weekends, holidays and non-working hours
6/1/2010 9:43 AM - 6/7/2010 1:45 PM
Here is the closest that I have gotten; however, this formula gives me a result of 96:
=IF(AND((WEEKDAY([Resolved Date],2))<(WEEKDAY(Created,2)),((WEEKDAY(Created,2))-(WEEKDAY([Resolved Date],2)))>1),(((DATEDIF(Created,[Resolved Date],"D")))-(FLOOR((DATEDIF(Created,[Resolved Date],"D")+1)/7,1))-3),(((DATEDIF(Created,[Resolved Date],"D")))-(FLOOR((DATEDIF(Created,[Resolved
Date],"D")+1)/7,1)*2))*24)
Any and all assistance is greatly appreciated!

I don't know how to exclude holidays but i exclude weekends(Sat&Sun)-
IF(ISERROR(DATEDIF([Start Date],[End Date],”d”)),””,(DATEDIF([Start Date],[End Date],”d”))+1-INT(DATEDIF([Start Date],[End Date],”d”)/7)*2-IF((WEEKDAY([End Date])-WEEKDAY([Start
Date]))<0,2,0)-IF(OR(AND(WEEKDAY([End Date])=7,WEEKDAY([Start Date])=7),AND(WEEKDAY([End Date])=1,WEEKDAY([Start Date])=1)),1,0)-IF(AND(WEEKDAY([Start Date])=1,(WEEKDAY([End Date])-WEEKDAY([Start Date]))>0),1,0)-IF(AND(NOT(WEEKDAY([Start Date])=7),WEEKDAY([End
Date])=7),1,0))
-Thanks

Changing working and non-working days

Hi
I am trying to make a permanent (default) change in working and non-working days. I am living in Israel and our non-working days are friday and saturday. I want to configure these as the non-working days so I won't need to do it manually via the change work
time menu.
Thanks
Chen

If you are using project server then you can do it permanent from
PWA --> Server Settings --> Enterprise Data --> Enterprise Calendar then
You can configure either your stranded calendar or create a new calendar in which you can make Sunday to Thursday as working days and Friday and Saturday as non working days.
You have to do it manually. There is no tool available which will do the same for you.
Where as if you are using Microsoft Project professional stand alone then for every plan (MPP file) you have to do it.

HT3310 I have an iphone 5. Speaker works but I cannot hear through the apple earbuds. Tried multiple earbuds and none work. But they work in other iphone 5.

I have an iphone 5. Speaker works but I cannot hear through the apple earbuds. Tried multiple earbuds and none work. But they work in our other iphone 5. Has anyone been able to resolve this without pursuing a replacement ? If so what was the fix?

You're not using a supported carrier. What did you think Apple was going to tell you?
As fizzDripper suggests, contact the SIM card provider. How to make an unsupported SIM work on your phone is not Apple's problem.

I have three ipods, none of which is being recognized by my itunes. I have the current editions and tried different USB ports. The mouse works just fine in the USB port. I have reset the ipods. Any ideas if it's the USB or the ipod or what's going on?

I have three ipods, none of which are being recognized by my itunes. I have reset each ipod, with no results. I wonder if the problem isn't with the USB ports. The mouse works fine in each port; nothing happens when I plug in the ipods. I have tried two different USB cables. I have no other USB devices with which to test. I have made sure I have the most recent updates and rebooted the computer. Any idea what is going on?

Did you already have a look at this article?

Non operational USB ports and stuck on grey apple start up screen

Two problems
1. USB ports are non operational. I believe I fried them by accident. When hooking up an external USB hub, I may have connected an incorrect power supply. Now the USB ports on the front and back of my tower are non operational/do not work. As a work around, I bought a USB pci card and installed it. This has been working for my keyboard, mouse and external hard drives but my iPhone will not sync. My ilok is recognized in system profiler but I cannot download anything to it.
Anyone know how to fix this? Is it possible I fried my main USB port?
2. I was reading different threads and a possible solution to the USB port problem was to reset my PMU. I have no clue why or if this would fix it but I gave it a try. Disconnected power supply and everything else after shutting down the computer. Found the pmu button on logic (or is it the motherboard or is it the same thing?). Pressed it, waited 20 seconds, put computer back together, connected power supply mouse and keyboard and tried to power up. The computer would not power up and the front power light was on but would not power up/boot. In a dumb panic, I opened up the tower and pressed the pmu button again without disconnecting the power. This seemed to work bcause my computer powered up! A red light on the logic board turned on and I got to the grey apple screen. This is where it froze. Hard reset, powered up, same problem. Unplugged power supply and tried again. Same problem. Tried pmu reset (unpluged power this time) and a repeat of the first pmu attempt. I tried starting up with cmd opt o p (I forget the exact letters but it was a reset with starting chimes), then I tried reinstalling with boot DVDs. It would get through the first DVD then restart and get stuck. Finally, I got it to accept second Boot DVD and finish installing and tried starting in safe mode. Got to safe mode and went to disk utility and checked first aid. No reported repairs necessary. Copied all files needed from HD and shut down. The computer did not shut down properly (this has been an ongoing problem before all these current problems and it has had problems booting fulling with hard resets needed once and a while). From here I tried restarting, pulling power supply, staring again and it keeps gettin stuck on grey apple loafing screen. The spinning wheel spins and then gets stuck, fans increase in speed and nothing. I can get back to safe mode either.
I'm very wordy I guess but more info the better, right?
The tower is very very very dusty. I will compress air it to clean it and attempt to clean connectors with alcohol. I will let it sit over night disconnected an then try powering it up.
What could the possible problems be? What can i do? Any suggestions on proper cleaning. I know how to ground properly and not to use a vacuum. I might have pressed the pmu button more than once. I'd the battery dead? Could it be a power supply problem. ****, I'm out of ideas and I really tried solving without posting but I'm poor and need my computer! Help!

L550/010 USB port not working properly, non-standard USB ports

I wondering if anyone can shed some light on this strange problem I'm having with my laptop USB ports.
Background.
I have a USB device (CED-M2 USB Chronograph). The device comes with Windows 7 software to upload fps readings.
The CED has a calculator style keyboard - so you can lookup data without the laptop.
My L550 PSLWSA-01000Q, is running Windows 7 professional.
Problem.
When I connect the CED into the USB port the buttons on the CED no longer operate, As soon as the USB lead is disconnected the buttons work. Uploading the data doesn't work either. The buttons freeze occurs as soon as I plug into a powered USB port (even if user not logged into Windows and programs are not running).
I've installed the upload program onto two PC's at home (Vista Home and Windows 7 Home) and both PC's connect to the CED and upload fine. Furthermore, the CED push buttons works perfectly! So, this leads me to think that the hardware or signals from the laptop USB ports is not standard.
I've tried all three laptop ports (e-Sata/USB and normal USB ports), same problem.
Any ideas what could be causing this problem?

Hi Jerry
Firstly, thanks for repsonding.
All L550/010 USB ports appear to work well on other devices (Sierra Wirless card, HP optical mouse, HTC phone), doesn't matter which port (USB, Esata/USB) all works fine with these units.
I've tried connecting the Chrono via a USB 4 port expander - same problem, no comms, chrono buttons locks up. Connect to Home PC running Vista Home and Windows 7 Home and works fine 9 - just can't take those to the range.
The Chrono unit is self powered (9V Alkaline) and it's new, so USB supplied 5V is not a problem.
The buttons seize whenever the laptop is powered up. Also, if the chono unit is powered down, connecting the USB lead to the laptop turns it on (wakes up). This wake up functions on both home desktop PC's and laptop (good), however, with the laptop I can't power down the Chrono as the buttons don't work.
Whilst laptop connected, and rebooting the Laptop, the Chrono buttons will work just before the Press F2 for setup screen comes up - so could it be electrical.
I've downloaded the latest BIOS from Toshiba and Intel chipset too - no change.
I got the unit to connect once tonight - when I plugged my mouse in at the same time - USB configured for mouse, and whilst doing that the Chrono worked. Once mouse working, Chrono stopped. Can't repeat results.
