Screen flickers when resuming from sleep mode

I have a newly brought T430 laptop with the Nvdia graphics card. Sometimes when I resume from sleep mode, the screen flickers before entering into the desktop view.
Is this a problem or normal? I hope nothing is wrong with my gpu. Is there a way to check?
Thanks!

It is definitely not a Leopard bug because it has been happening on every portable Mac I've ever had.
I don't agree. I had no problems at all with my MacBook Pro running Tiger. I initially did an upgrade from Tiger to Leopard and when the problems started I assumed it was a problem with the upgrade. I then completely erased and did a clean install of Leopard. The problem has actually gotten worse since I did the clean re-install.

Just close the screen, wait for it to go back to sleep, then open it again. It will probably be fine.
As I mentioned in my opening post, I've gone through that song and dance more times than I can count. I've closed it, waited for as much as an hour, opened it back up...same problem. I've hard powered it down, closed it, disconnected the AC adapter, removed the battery, opened it, held down the power button for 15 seconds, re-installed the battery, reconnected the AC adapter, pushed the power button, and the display will still be dark. It's sometimes taken as many as 5 or 6 iterations of that process before it will finally reset whatever problem it was having and boot normally with a functioning display.

T61 - WWAN does not connect when resuming from sleep mode

Hi.
I have a T61 with integrated WWAN, which works perfectly - except I use sleep mode a lot, and when i resume from sleep mode, WWAN doesn't connect, I always get the same error - IP configuration failed. If I restart my OS, WWAN works normally again.
So far i have tried on Windows XP, Vista 32, Vista 64 and Windows 7 32 bit - always the same!
I connect via Access Connections, maybe there is a known issue?
Thank you, B

This bugs me as well. With the new Verizon software I just installed, it says "Adapter Disabled" when I resume from sleep.
I suspect a driver bug that needs to be adressed.
I use Vista Business 32bit, but had the same problem with XP.

Sound not staying muted when resuming from Sleep mode

The subject says it all. When I resume from Sleep mode the sound is not staying muted. I have found a third party app to get around this but I would rather solve it without having to run something else in startup.
I have a HP Pavilion dv7-2206tx Entertainment Notebook running Windows 7 with all the latest updates installed.
Anyone know how to prevent this from happening?

Have you seen if the problem occurs if you use the nouveau drivers?

Error in AJAX call when resume from Sleep mode?

We have developed a HTML5 web app and added it to home screen the app is working fine. But the AJAX call is not working when we resume the app from SLEEP MODE. If the app keep opened.
THIS ISSUE COMES ONLY IN iOS8.
Please give the solution for the above issue.
Thanks

Sounds like maybe the eject mecinisim is stuck..? Try inserting a CD or DVD and then Eject it to see if that makes a difference.
If not, try reseting both the SMC and PRAM
as per > Resetting the System Management Controller
and > Resetting your Mac's PRAM
Then if it is still acting up, contact Apple or your local AASP

Helix freezes when resuming from sleep mode

Every time I close the lid, the Helix enters sleep mode. Then, when I reopen it and enter my password, the computer freezes, most often taking me to the Photos app. In order to resume work, I have to use the Power button to shut down and restart. Very frustrating -- can't even walk across the room with the lid closed without having to restart, often losing whatever I was working on. Any ideas?

Hi Yvonnerose,
Thank you for the reply!
1) Update your bios and update the Intel Management Engine firmware to the latest. Below is the link to enter the downloads page and download latest application accordingly, please click on "Select Product" then in "QUICK PATH" enter the MTM no. select the exact model.
http://support.lenovo.com/en_US/downloads/default.page#
2) if issues still persist, please check the installed RAMS or he secondary RAM installed as in some cases it has been found cause the interruptions. If the system is shipped with dual memory try running with only one RAM first to check if problem still persist.
3) If both of the above fails please contact nearby Authorized Lenovo service support teams, they will able to advise according on the next course of action.
Hope this helps.
Best regards,
Hemanth Kumar

T510 Blank screen occasionally when resuming from sleep

I've been having a lot of trouble with my video driver recently on Windows 7 32-bit
Right now I have the NVS 3100M driver version 8.17.12.8562 installed.
When resuming, the screen will go bright pink for a moment then show the login screen,
but once in a while it will just remain blank. (Not on an external moniter, but the lappy itself)
A few BSODs once in a while that typically point to the nvlddmkm service
Any solutions or similar problems with these drivers?

Hello Nigel,
I suggest you, if you are able to login into Windows then please update your Graphics driver, Power Management and BIOS from the below mentioned web link.
http://support.lenovo.com/en_US/research/hints-or-tips/detail.page?&DocID=HT063289
Please download and install the driver according to your Operating System and also check the release date of the driver. Alternatively please reinstall your Operating System. It might resolve the issue.
Regards,
Harish

Wifi problems in Mountain Lion when resuming from sleep mode.

I have recently upgraded my Macbook Pro to OS X Mountain Lion. I have been noticing that everytime my computer enters sleep mode and I wake it back up to use again the wifi connection is lost or frozen. If I roll over the wifi bars at the top of my desktop the rainbow wheel appears over my toolbar and I cannot access the internet. The only way I have found to fix this problem is to restart my computer and connect to the internet or use a program or set the energy settings to prevent the computer from falling asleep. This problem has really been agravating me for the past couple of weeks. Has anyone experienced a similar problem or found a permanent solution?

Ok, so it's certainly a Broadcom wifi adapter. The Lenovo nomenclature refers to it as "1x1 11b/g/n Wireless LAN PCI Express Half Mini Card Adapter (43142)". But why are you trying to install Realtek drivers?
The only driver I could find is this one, for Windows 8. Please uninstall all other drivers, reboot and install this one, or let Windows find a suitable driver and see if that works. Also please read the document from the link, it gives detailed instructions on installation and uninstallation, how to check version number etc.
It might be the case that you have to wait a bit for an updated driver for win 8.1 to resolve the problem, but It doesn't hurt if we try to find a solution.

[SOLVED: clear CMOS] Reboot when resuming from sleep mode!

Hello all,
System Specs(Desktop):
uname: Linux 3.10.10-1-ARCH #1 SMP PREEMPT 2013 x86_64 GNU/Linux
GPU: nVidia GTX-550 Ti - Drivers: 325.15
The sleep and hibernate modes work as they should. But lately whenever I tap a key or press the power button to wake the pc from using either of the suspend modes, it reboots instead of turning on(hardware) and prompting with the loging screen like my laptop does.
I've check the wiki and searched the forums but nothing is close to what I'm experiencing.
Any help or links to something I might missed is greatly appreciated.

17" MBP - no screen ilumination when resuming from sleep

I've had the bug since installing the latest Lion update 10.7.3
I never shut down my 17" MBP, just close the lid and let it sleep, however, since the latest Lion update when I open the lip the screen illumination comes on briefly and then turns off - I then hit one of the screen brightness buttons (F1 & F2) and the screen illumination comes back on.
How do I go about correcting this ?
I've read that reseting the power controls could resolve this bug, but not sure how to perform the reset.

A printer that's not connected had a print jog in the queue.

T60 Type 2623 Blue Screen on Resume from Sleep Mode problem solved - XP Pro

I hope that this post ends some frustrations for some people.
I hope that IBM deals with this issue by getting ATI to fix the video driver issue.
After three months of tracking down blue screens when resuming from Sleep Mode and some lockups while working, I have identified the problem on my T60 Type 2623 running Windows XP-Pro and all service packs and updates. The Sleep Mode resume issues were intermittant and it would be fine for a day or two and then reboot on Resume or reboot every time I used Resume for a while. For months the Blue Screen would reboot and attempt to send the message to Microsoft using the logs, but the logs were always corrupted. I disabled every driver that I could and the problem continued for months.
The problem solution came about when I decided to try my Rhapsody Music account after many months of not using it. I kept getting a message about DRM (Digital Right Management) being disabled and Rhapsody software could not self-fix this. So I finally called Rhapsody and they spent over an hour with me trying to get Rhapsody to work. The support person asked me about my computer and I noted that it was an IBM T60. He then asked about my Video Card and I responded that it was an ATI Mobility Radeon X1300. After a few minutes on hold he asked about my driver version which was 8.442.3-080103a1-057754C the set from January 31, 2008. He noted that there is a known problem wit the 8.4 driver and it interferes with DRM. He had me go to control panel Settings and Hardware and then roll-back the driver to the prior version.
After a reboot, the DRM issue was solved and I soon discovered that my resume from Sleep mode no longer crashed. In fact it has been fine and crash free for over a month now. I have noted that the older driver can sometimes resize my screen to something like 600 X 800 if I close the lid under certain circumstances, but that is just a function key reset to get my normal desktop resolution back. At least it is not a blue screen reboot with a corrupted log file.

Solved!
Go to Solution.

Unfortunately I could not fix the problem so I wiped my system and loaded all new drivers before I found this posting.
Is there a way to get the old ATI driver that works? The only one available on the ATI and Lenovo website is the latest one with the problem. I agree with you David, Lenovo should have fixed this problem already with ATI.

Marching ants when resuming from sleep - software or hardware issue?

Hello -
My new T400 thinkpad works great except periodically when resuming from sleep mode, I get squiggly marching ant lines across the screen. I can continue to log-in, open apps, etc but the lines won't go away until I restart.
Does anyone have any idea whether this is a hardware or software issue? I'm running Win 7 Enterprise.
Thanks in advance for any feedback.

This problem was fixed by disabling and then re-enabling the video driver. Updating the driver didn't work; it had to be diabled and re-enabled. According to the technician the marching ants were a result of an incorrect refresh rate (it was refreshing either too fast or two slow).
At least that took care of the issue on my T400. Hope it helps!

Macmini 2011 on lion, goes to a blue screen om monitor when awakening from sleep mode, last 3 or 4 seconds, can anyone help? Thanks

Macmini 2011 on lion, goes to a blue screen on monitor when awakening from sleep mode, last 3 or 4 seconds, before desktop appears, can anyone help? Thanks

Depending on the system configuration, this may not
be unusual. The Mini that I use for my home theater,
which is connected to a receiver then to a TV, all via
HDMI usually takes a couple seconds to come up just
the way yours does. Same happens when I switch sources
on the receiver. Actually, it starts with the blue screen and
will sometimes flash before the desktop comes up.
It seems that when HDMI goes dormant, there is handshaking
that needs to be re-established, at least thats my SWAG on it.
On the other hand, the Mac Mini Server that I use as a work
station and is connected to a Thunderbolt Display, wakes to desktop
in a second, maybe two. On this combo, it just comes up to
the desk top.
It also probably depends on what processes were active when
the Mini was put to sleep. So it may take some time for it to get around
to reloading the desktop.

A problem with a macbook retina when resuming from sleep.

After many questions and a complete reinstall at an apple store I stil have the problem. When resuming from sleep, and sometimes seemingly at random, the machine swaps to a different application. I run several desktops full screen and it will swap to a different desktop virtually every time I resume. Not a huge deal but annoying. It seemed to start happening when I installed Office for Mac, but that might just be coincidence. I'm not running anything weird in the background, just a utility to show when the graphics card is active. Any help would he greatly appreciated.

Running games at full resolution may produce occasionally-choppy video, but nothing that would prevent you from playing. I mayself have played Portal and Left 4 Dead 2 on mine, and I haven't noticed any problems.

Touchpad and trackpoint problems, especially when resuming from sleep

I am having persistent problems with the touchpad and trackpoint on my L530. I prefer to use the trackpoint usually, and found that the touchpad was super-sensitive and caused the cursor to jump around during normal (touch) typing so I disabled the touchpad. Next time the thinkpad resumed from sleep mode, the mouse was frozen. Nothing would reactivate it. I had to switch user, which temporarily fixed it, and then reactivate the touchpad.
If I try and change trackpad settings at any time other than directly after a reboot, the settings are greyed-out and I can't touch them. Right now, both trackpad and trackpoint are completely dead again, but I've plugged in a USB mouse and that seems to be working, so I've given up fiddling with it. This will be a pain when I'm moving around with the laptop though!
The OS is Windows 7. Yesterday I went looking for the most recent driver, uninstalled the existing one (as per guidance) and installed the new driver. No luck.
I've heard this is a common problem and apparently installing a generic driver works, but I'm not completely sure what to use. Anyone know?
Oh, and I'm not sure if this is related, but quite often when I resume from sleep mode the keyboard is also dead. However, if I switch user it comes back to life. So annoying but not the end of the world.

Thanks for posting this information in this forum. You just saved me a couple thousand dollars!
Based on my experience if you want to get this problem fixed as soon as possible you need to do the following:
1. www.apple.com/feedback
2. Post a video of the problem on www.youtube.com
3. Send www.apple.com/feedback a link to the video on youtube.
4. Encourage others to visit your youtube video and to post their own.
Good luck!

Airport Card turned off when resuming from sleep - New since 10.6.6

I use safe sleep regularly, as I use my laptop at both work and home. Ever since the update to 10.6.6 though, I have had to manually turn my Airport connection back on after resuming from sleep.
Previously, although it was unreliable about connecting to a preferred network (an unrelated, but equally frustrating issue*) at least it would remain on. Now I've had to add the icon to my Menu bar just so I don't have to dig into System Preferences every single time I reawaken my laptop.
Does anyone know why this is happening, and if there is anything I can do to prevent it? I apologize if this has been asked before, but when I searched I was unable to find anything.
*This issue is unrelated and not the focus of my post, but if you happen to know about it I would absolutely appreciate your input.
When resuming from sleep, despite being between 5-20 feet from my preferred router I will often receive a dialog asking me to select from a list of SSIDs and enter a password even though that information is already saved. Then, once I complete this information Airport doesn't actually connect and the only way to resolve the issue is to turn Airport off and then back on. After this, it will automatically connect with no problems and remain connected until I put the computer into Sleep mode again.

Maybe check in your keychain and verify the password saved is correct for your wireless router?
Do you broadcast the network name?
Could you describe "unreliable about connecting to a preferred network"?
Is "use secure virtual memory" checked in the Security preference pane? If so try unchecking that maybe? If it's a hibernation issue sometimes that could cause weirdness.
