Weird noise coming from computer when 'waking up' from sleep mode

Hi everyone,
I recently upgraded to Yosemite 10.10.1 - specs are in the attached photo below.
Since yesterday, when I turn on my computer, or 'wake' it up from sleep mode, it makes a strange and noticeable whining noise. I've had the computer for around two months and it has never made such noises. The noise lasts for about 1-2 seconds. Aside from that the computer is operating as usual.
I reset/shut down the computer several times and also did a PRAM reset. I have no idea what the issue may be and can't seem to find anything of relevance in the community. Should I go to an Apple Store? Is there something to be fixed or will the computer need to be replaced?
Thank you all for your time!

Sleep mode - I use sleep mode for scheduled recording of TV shows in Windows Media Center. If I shut down, no recording.
Yea, waking up to do a recording is certainly a valid scenario. I gave up on Windows Media Center right before they came out with an XBOX that is actually quiet and could be used as an extender. We've been a TiVo family since those noisy XBOX days.
Regarding sleep/hibernate, I just got tired of my machines waking in the Lenovo dock and having to reset application position, screen resolutions, and all of the other crap that seems to happen to ThinkPads on a resume. That doesn't even take into account the black screen of death or other reliability issues I've seen over the years.
I am firmly a shutdown guy now. It's clean and I know what I get when I press the power button again. With 15-25 second boots and fast I/O, the reliability outweighs the perceived time savings.
We haven't discussed what might be corrupting the original posters file system. That is disconcerting. Sounds like a Crucial M4 firmware issue. If that is the culprit, there's going to be hell to pay on the mSATA M4 based Ultrabooks assuming it has the same bug.

OSX 10.9.1 macbook pro 13 retina - wifi does not reconnect automatically when waking up from sleep mode since I have a Bluetooth apple magicmouse

Hello,
My config is OSX 10.9.1 new macbook pro 13 retina (2014).
The wifi does not reconnect automatically when waking up from sleep mode since I have a Bluetooth apple magicmouse.
It was not the case before I bought the BT mouse.
Is this problem between Wifi and bluetooth coming from the OS?
Is there a fix already available or scheduled?
Thanks

Hello alexandrefromfrance
Check the Symptom: The network connection drops unexpectedly section for steps on what to do when your MacBook Pro does not connect after waking from sleep. I have also quoted the section on troubleshooting the issue as well.

High power comsumption and wrong setting when waking up from sleep

See here for some more information: http://forums.lenovo.com/t5/Windows-7-RTM-Discussion/High-Power-Consumption-with-Windows-7/td-p/1668...
Settings: T400, integrated GPU,"maximum battery live" power sheme, brightness level 3, wlan on. Newest switchable graphics driver, power manager and power management drivers installed, SU4 didn't find newer drivers.
Power consumption is between 12-16W most of the time, whereas it was close to 10W on XP, from what i heard from a friend, i installed win7 on my machine right after i bought the thinkpad.
When waking up from sleep( i think hibernation as well) power consumption is abnormal, because both GPUs are activated. You have to switch to to the dedicated and back to the integrated via power manager to deactivate the ATI, which is very annoying.
Is lenovo working on these issues or are there any workaroungs already?

I've got similar problems on a T400 with hybrid graphics running Windows 7 x64 Professional, upgraded from Vista x64 Professional. I've upgraded everything to the latest (driver, bios, etc etc) using System Update.
When I boot up from cold, and switch to using batteries, the power consumption is around 8w. Very good.
Then I suspend, and resume from suspend, and the power consumption shoots up to like 20w. Horrible.
Then I manually switch to "High performance" and then back to "Energy saving", the power consumption comes back down, but to >9w, which is like 13% above the original 8w level. Acceptable, but not good.
This seems to indicate there're at least two problems with the power management aspect of T400 + Win7 x64:
First, there is the well-known problem that both internal and external graphics cards get turned on upon resume. Lenovo, please fix this problem. It's completely unacceptable to have to manually perform that switching every time one closes, and then opens the lid, or loss 60% of the battery life. And I do need to use the external GPU from time to time, so disabling it at BIOS level is not acceptable either.
Second, there is the more subtle problem that some other hardware/driver besides the graphics card makes the T400 draw an extra >1w upon resume.
I really wonder if these problems occur with T400 preinstalled with Win7 x64. If they do, shouldn't every major laptop review sites take notice of the defect and warn people. If they don't, then I do not really see why it's so hard for Lenovo to provide earlier users with the right driver/registry patch/etc to enable the correct behavior. As far as I know, these problems have not been fixed since Win7 came out.
Finally let me add that other that this, I'm extremely satisfied with my T400/Win7 system. The thermal dissipation, noise level, and durability are just top-notch. But this just makes the above mentioned problems more of a thorn in the side!

When I disconnect my iphone 3gs(iOS) from computer, the device disappears from my itunes. This prevents me from doing a wireless sync. how do i fix it so that my device stays on itunes without having to plug it in all the time?

When I disconnect my iphone 3gs(iOS) from computer, the device disappears from my itunes. This prevents me from doing a wireless sync. how do i fix it so that my device stays on itunes without having to plug it in all the time?
it worked the first few times i did it but the next day after i closed out of itunes once, the device only appears when i plug in my phone.

Whenever a menu choice is grayed out, that is because you have Restrictions turned on in Settings. Be sure to turn it off.
You are confusing an itunes store account with an icloud account. You two can continue using the same ID for itunes (thus sharing purchased music, apps, etc.), but you really should have separate accounts (different IDs) for icloud, since an account is intended for one user to keep his/her devices in sync.
To create a new icloud account, go to
http://www.apple.com/icloud/setup/
Then go to Settings>icloud and scroll to the bottom of the screen and tap Delete Account. (have restrictions turned off) That will disconnect the device from the account but will not delete data in icloud or other devices. Then sign in using the new ID.

Disconnected from ANY chat program when I go into sleep mode

I am using an airport express connection with road runner. When my computer goes into sleep mode, any chat program I am using is disconnected -- this happens with AIM, iChat, and Netscape Navigator's chat screen. As soon as I move my mouse, or touch the keyboard, and go active, AIM automatically reconnects. Any ideas on how I can remain signed into a chat service when I go into sleep mode?

In sleep mode your mac only keeps the data in the RAM. all other things will be turned off, so that it´s impossible to stay online with the chat applications.

Need help - wifi gets disconnected when it goes to sleep mode - iOS 6, iPhone 5, WPA Enterprise

Hi, I have read a lot of discussions regarding wifi gets disconnected when it goes to sleep mode on iOS 6, mainly on iPhone 5.
Here is my configuration and it just keeps disconnecting wifi connection once it goes to sleep mode
iOS 6
iPhone 5 white
Purchased on Nov 3
Work wifi config: WPA Enterprise
I tried to manual add the wifi but it did not work. I tried all except for upgrade to iOS 6.0.1. I had a call to Apple Support and the guy told me I could not trust everything i read from here (well, how dare he is!!!). But I did all I could think of, and read from here.
I am with ATT and I do not have a receiption at all at work. I have to turn it to airplane mode, and use the wifi connection. I put my iPhone 4 with iOS 5.0 side-by-side to compare. My iPhone with iOS 5.0 DOES NOT disconnect the wifi connection when it goes to sleep mode; but of course, we all know, iPhone 5 with iOS 6.0 does
Any helps would be so much appreaticated. I am considering to return the phone to apple store, and cancel my 2 yrs extended contract with ATT. I might think to get another one once they have the issue fixed. It is no point to have an expensive paper-weight at work while I can't use the celluare nor wifi connection.
Thanks again,

Hi ChrisJ4203
I have tested it at home wifi tonight. My phone and my wife's iphone (both iPhone 5 with iOS 6.0) do the same.
With cellular data on (aka airplane mode OFF) with WIFI ON
Wifi icon replaced by ATT's LTE icon once the phone was waken up from sleep mode; but within 2 secs, the wifi connection got reconnected again.
With cellular data OFF (aka airplane mode ON) with WIFI ON
WIFI icon disappeared from the top bar after both phones were waken up from sleep mode. It took a while to reconnect to the wifi network (more than 10 seconds).
On a separate note, after i rebooted my phone, i can see it does "searching" the ATT's signal, then it shows "No Service", then next second, it shows ATT with full bars and LTE icon.
My question is, i have never noticed the "No Service" showing up from my iPhone 4. The "No Service" shows up on my wife's phone too. When I first got her phone and was doing the installation, I had noticed the cell signal dropped from full bars to no service, then within few seconds, it went back up. I have not had time to test on her phone again, but it is something I will be monitoring for. I wonder if anyone has similar experience like this.
anyhow, any feedback on how to fix the wifi got disconnected while in sleep mode would be very helpful.
thanks,

Is it best to turn off your computer or put it in sleep mode.

Is it best to turn off your computer or put it in sleep mode.
I have a MAC Book Pro
2.4 GHz Intel Core 2 Duo

Well. Apple recommends to put the Mac into sleep mode if you are going to use your Mac after a short period of time, and they only recommend to turn it off when you are not going to use the computer for several days.
In sleep mode, your Mac consumes only a small battery capacity, so it's worth to put it in sleep mode. Also, it's much faster than turning the computer on every time you want to use the Mac

so I have called HP tech support 12 times over the last 6 weeks and still my HP Officejet 4620 loses connection overnight. Of course becasue it was a birthday present I spent more time than I normally would have on this issue. While the tech are very polite they have not fixed my problem and now it is too late to return printer to store. This is a lot of money wasted and I think they need to admit this is a bug in this printer and resolve the problem!!!!!

How to stop the computer from changing its local network name when waking up from sleep mode

How do I prevent a mac mini from changing its' network name automatically when it wakes up from sleep mode... It will wake up and display a warning that the network name is already in use and it changes its name to (n+1) name with number after it... I know that there is no other device with that name because the only other things on the network are 2 hard drives (one being used for time capsule) and a printer..
This is very annoying and needs to be fixed.... don't tell me to make the computer never sleep because that defeats the power savings settings under power management.

Go to System Preferences>Network>AirPort and delete your network from the Preferred Networks box. Reenter your network information. Make sure that AirPort is the topmost listed interface when you Show Port Configurations. Apply the changes and Restart. Does it work now?

Weird noises coming from DV3-4110ej laptop

Hello everybody ! .
My laptop was sent to repairs few weeks ago due to weird noises (which i can only describe by words=>sound like long ' bzzzzzzz
' sounds which will not last the whole time, but every 2-3 seconds (for about 10-15 seconds,maybe more) ) .
According to the technician, the problem was in the hd, which was replaced, but still, the noises didn't stop.
I've already tried formatting the new hd,defragment,tune up (by hp), read that it has something to do with the AC unit - connected it to the battery - no good.
about the comp (if it may help) :
1 . DV3-4110ej , model number XM719EA#ABT
2. os : Windows 7 64 bit
Thanks in advance !

When waking up from standby, monitors power up but no picture is displayed. HP ENVY Phoenix h9

Product: HP ENVY Phoenix h9 PC Series
Product #: H3Y51AA#BL
Model: h9-1387
OS: Windows 8 64-bit
Monitors: DELL 2407WFPHC x 2
Updated graphics drivers to latest non-beta version.
Hello,
Since purchasing my PC a few months ago, there has been one "display" problem after another. This is the current problem:
When stepping away from my computer, I lock it via Win+L and shortly after my monitors turn off. When returning a short time later, I attempt to wake up (But not really "wake up"... To try and fix previous display problems, I've already disabled hibernation and sleep options) my computer by moving my mouse. This causes the monitors to exit standby and power up, but all that is dispalyed is black screens when I should have been presented with the login screen.
Mouse and keyboard clicks do nothing and I'm stuck at black screens. To continue, I press my PC's power button which causes the hard drives to spin-up and shortly after the computer turns off. I press the power button again and the computer boots to the login screen where once I enter my password, Windows loads and all my programs etc are displayed as they were before I locked my PC.
You can see previous problems I've had listed below, hopefully they will also help you detect the cause of the current problem.
Please help.
Thanks!
Peter
Previous problems that I've had:
1) When waking from hibernation, the computer would not wake monitors from standby leaving no way to login and save work. Hard reboot required. Solution: Disable Windows hibernation features.
2) Error along the lines of "Display driver failed and have recovered". Possible solution: Disabled hardware acceleration in Firefox.
3) When waking from standby, I find my 2 monitors have merged into one, and at a different resolution than normal. Once entering password to login, programs that were on seperate monitors are now on the same monitor. Right-clicking the desktop and selecting "Screen Resolution" -> "Detect" would set the monitors back to normal until the problem occurs again. Possible solution: Updated graphics card driver. Not sure if this problem has been fixed, it may have just been covered up by the new problem mentioned above.
This question was solved.

Hey peterallcdn,
I'm sorry you're running into this resuming from sleep issue. Sometimes services that are trying to resume can cause issues like this. I would suggest trying a clean boot (booting with only essential system services running) and then seeing if it resumes from sleep properly.
Here are the steps to disable non-critical services:
1. Windows + Q to bring up Search
2. Type 'msconfig' and press Enter
3. Click the Services Tab
4. Check the Hide All Microsoft Services box
5. Click the Disable All button
6. Click Apply and Restart
When you restart Windows should only load essential system services, no 3rd party software. Lock the computer and let it go into sleep mode as you usually do and then try to resume from sleep. Let me know what the result of that is.
I have seen other cases where Google Talk or antivirus programs will prevent the computer from resuming properly.
