X200s BSOD when resuming from hibernation

I always get a BSOD regarding CLASSPNP.SYS when trying to resume from hibernation after the laptop has hibernated because of critical battery level. The BSOD also says that "physical memory dump failed with status 0xc000009c". If I just choose to hibernate it resumes just fine. The problem only appears when the system hibernates by itself.
Any ideas?

T61p: Vista - BSOD when resume from sleep / hibernate, casued by classpnp.sys

I've got a T61p (Type: 6457) with preinstalled Vista, later upgraded with SP1. Everything worked like a charm, untill a week or so, when the BSOD appeared when either resuming from sleep or hibernation.
I've checked the minidump, and it seems as the classpnp.sys is causing the trouble, however, I've yet not found a good solution to fix the problem (I'm close to doing a restore to factory install, but would like to avoid if possible
Anyone?

There's an issue with your GPU, video driver or both...try running this for a while:
http://freestone-group.com/video-card-stability-test.htm
If there's an underlying problem, this test will reveal it. And when I say "a while" I mean for an hour or more...
Please be advised that if your GPU is on its way out (I've had them fail on T60p due to VRAM corruption) this test might just finish it and push it over the edge. Proceed at your own risk.
Good luck.

T440p BSOD when resuming from sleep

Hi,
I have a T440P that was getting blue screen of death every time I was trying to resume it from sleep. KB2459268 fix from http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS019407 and reduced the occurences from 100% to maybe 75% of the time.
The problem is very annoying as I have to keep the laptop always on in order not to reopen all applications every day. The BSOD description is:

* Bugcheck Analysis *
SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M (1000007e)
This is a very common bugcheck. Usually the exception address pinpoints
the driver/function that caused the problem. Always note this address
as well as the link date of the driver/image that contains this address.
Some common problems are exception code 0x80000003. This means a hard
coded breakpoint or assertion was hit, but this system was booted
/NODEBUG. This is not supposed to happen as developers should never have
hardcoded breakpoints in retail code, but ...
If this happens, make sure a debugger gets connected, and the
system is booted /DEBUG. This will let us see why this breakpoint is
happening.

BSOD on resume from suspend with sandisk extreme ssd

Hello folks!
Has anyone had this happen?
After buying the sandisk extreme ssd and installing it, i get bsod every time when resuming from suspend.
I have tried other hdd with no problem, and tried a fresh install with win7 x64, but still have this problem with the sandisk..
Any ideas anyone would be aprreciated, thanks

I developed a waking problem from sleep mode when I changed out my ram to bigger. My Lenovo loses about 600mb of 'something' from memory between entering the sleep mode .. to waking up? I still haven't figured it out. You might want to try changing the memory sleep/suspend setting to just hibernate. You should wake up plenty fast from hibernate on that ssd. If using it.. you might also read up on the intel rapid storage technology. I read that needs uninstall/reinstall sometimes when changing to ssd.

Minor lag from GUI when resume from sleep

Hey people!
I've been on archlinux for a couple of months now and I have fixed bugs here and there but something I have just noticed yesterday (it would happen before but I couldn't say when it would occur) is that after my system resume from sleep (it's not slow, it takes 1 or 2 secs) gnome GUI is a bit slow and it doesn't stop till I reboot my pc (it doesn't occur until my pc resumes from sleep).
It's not that bad but quite annoying. I don't really know how to approach that kind of problem. I think it would be related to something like "gnome is not completly reloaded when resume from sleep and there are some infinite loop going on"...
I hope someone has a clue in here!

hey, sorry to revive an old thread, but this was the only other person I could find with this issue.
I had originally reinstalled power manager and the the pm driver because it wouldn't save any custom power settings. When I finally got it working, it wouldnt wake up from sleep just like the above user's issue.
Machine is relatively new win7x64 install with all updates (lenovo updates too) installed.
Would like to avoid a total reinstall if at all possible.

10.6.4 complete system freeze when resuming from screensaver-VMWare Fusion

I have a Macbook Pro, 3,1. I just upgraded to 10.6.4 and noticed the following symptoms:
Shortly after launching VMWare Fusion 3.1 running a Windows XP VM (from a Bootcamp partition), a series of pop up messages were complaining about a bad OpenGL driver. The message popped up repeatedly and wouldn't let me out, even though I kept pressing "Ok". I had to force quit Fusion, which caused a chkdsk on relaunch of the XP VM.
After a complete reboot, I started VMWare again. The Fusion complaints haven't shown up again, but when resuming from the screensaver, the system either completely freezes up, or the screen login window starts to flash rapidly and seize up. I'm running Spaces with 6 virtual screens. Whether I'm in the Fusion Spaces screen or any other Spaces screen, the system freaks out when resuming from a screensaver.
I use this system at work, so I have to be able to lock my screen when I leave my cube. The only way I've been able to ensure the system doesn't freeze up and cause a hard reset of the XP VM is to completely disable the screensaver and power saver features, such as Start Screen Saver = Never, Computer Sleep = Never, Display Sleep = Never and launch the login window by clicking on my user name in the upper right corner of the screen on the menu bar. Even that causes a sluggish screen and I'm not confident it will keep working. I also made sure (from day one) that the Windows XP screensaver functions were all completely disabled. I prefer to use the OS X screensaver for everything, if for no other reason than having a single screen locking/unlocking point for when I step away.
This was all working properly in 10.6.3. The only nit-nat I noticed about Fusion in 10.6.3 was that it had to be launched in the "Primary Window", which seems to be the upper leftmost Spaces desktop. If I ever moved it to, or started in any other Spaces desktop, it would also exhibit the same random lockups. Keeping it in the "primary" space seems to have stopped the lockups.
I noticed that there seemed to be significant updates to the OpenGL drivers in 10.6.4. I am experiencing an unfortunate side effect of these updates and hope I'm not alone and that a fix is coming soon. Looking at the other posts, there seem to be a lot of similar problems. I wanted to describe my configuration in case the Apple dev team reads these posts. Thanks.

I ended up doing an erase and fresh install of Snow Leopard (10.6.0), upgraded to 10.6.4 with the combo update, then a fresh install of all my apps, including VMware 3.1. Everything has been solid for 2 days now. I'm guessing that my system had a magic combination of issues that weren't visible in 10.6.3 but became obvious only after upgrading to 10.6.4. I had been upgrading my OS since 10.5.0 over the last 2 years and needed to do a clean re-install for some time now.
I'm guessing that others who are noticing problems with the 10.6.4 update have a similar situation with their installations. Think back on all the times a software installation failed, or the system required a hard boot. Plus, I had a lot of 3rd party apps on my box that never posted updates for later Snow Leopard releases, so who knows? Anyway, it's good to have a clean and snappy system again. A lot of my apps launch a lot faster now and survive the screen saver and power saver modes just fine.

When resuming from standby mouse-click/keyboard doesn't work.

When resuming from standby about 80% of the time the mouse on my Macbook Pro (Early 2011) stops working. I think it is a software issue. It appears that the mouse will do a click or click and drag but will not let go when removing my fingers. The issue only happens within 5seconds of waking up. The issue is only fixed with a hard reboot. I can bring up the shutdown menu, but am unable to slect shut down as the mouse/keyboard won't give input. This issue was present in Lion and was gone for the first few months of Mavericks but appeared again this week.
I can freely move around the mouse cursor and enter expose with three fingers but cannot select anything.
Any help would be appreciated.
Thanks.

You can use viewToModel() method to get caret position for x, y location. No need to click.

Stas

When resuming from screensaver

When resuming from screensaver screen is pixelated in large blocks about a quarter inch square. I can put in my password after i roll the cursor around enough to see where to click to put in my password. Is there a fix for that yet?

Just wanted to say that i got an adwise in the thread that i posted earlier that has worked for me.
Adwise form Softwater:
Try deleting this file:
~/Library/Preferences/com.apple.screensaver.plist
and then re-starting your mac.
Don’t worry, deleting the file is harmless. It will just recreate itself to default settings when the computer reboots. It may be that the current file is corrupt.
Note: to get to this file in Lion, you have to chose ‘Go’ menu from the Finder menubar at the top of the screen, while keeping the ‘option’ key held down. When you do this, you will see ‘Library’ in the Go menu bar. Click on it and navigate to Preferences and look for the filecom.apple.screensaver.plist and trash it.

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.

X220 very slow reconnecting to WiFi when resuming from sleep

So my X220 with the Intel 6205 card is having issues reconnecting to WiFi when resuming from sleep or hibernation. It takes about a minute for it to do so, though occasionally it will reconnect right away. Maybe 1 out of 20. When doing a cold boot or restart, it connects immediately upon the desktop showing up.
This was not always the case, in fact when I first got my X220 in June, I have not had this issue.... In fact, I don't know when it started happening, but it was maybe a couple months ago. I just thought it was my old router going bad. Well I got a new router, and it still happens. I have the latest Intel WiFi drivers from Lenovo, and I even tried downgrading to the previous driver from Intel's site. Still the same problem. I tried setting a default profile in access connections, and that does not help. In fact, it behaves the same way if I totally uninstall access connections as well. In fact I tried this on three different brand routers, and I can reproduce it on all of them (Asus, Netgear & TP-Link) so I think this is not a router issue. Other devices in the house reconnect right away with no issues (iPhone 4, PS3, Mac desktop, Dell laptop).
I currently have BIOS 1.24, but this was happening with 1.21 and 1.23 as well. My X220 originally came with 1.16, and I haven't updated it until 1.21. Unfortunately I don't remember that far back, if the problem started occuring then.
There was a brief discussion about this in another thread, but it went nowhere so perhaps this will get more attention. At least one other user reported the same issue.
Here's a clip of exactly what happens. When i press the button or open the lid from sleep, the windows wifi icon will start spinning for a few seconds, then turn into an X. then only about a minute later, does it quickly connect to the wifi and I have full signal. Manually clicking on the icon and selecting the access point does not speed up the process. It will only connect when it wants to, about a minute after resuming from sleep/hibernation.

Solved!
Go to Solution.

Normally when a laptop running windows tries to connect to a network, it may also seek to identify certain components on the network, for example, asking the router "Who are you?". In your case, maybe the config are corrupted because the network address entries are messed up. Queries send out to the network come back with no replies, and the computer waited for the default time till timeout and it gives up.

Access Violation in aapltp.sys when resuming from sleep.

Hello,
*I have diagnosed an issue in the aapltp.sys (touch pad) driver included with the MacOS 10.6.2 DVD. This issue causes a illegal access to be performed by this driver when the computer resumes from sleep (I have never reproduced it when resuming from hibernate or during normal operation). This issue occurs about once in every 10 resume operations, with both Windows 7 and Windows Vista. I have not experimented other versions of the OS.*
*The version of this driver included with 10.5.x DVD does not have this issue - this is a new regression.*
*In summary, KeyMagic (another apple driver) running on a system thread calls the OS for a dispatch (FxDevice::Dispatch). This ends up being routed to aapltp. While executing, aapltp dereferences a memory position offseted from a register that contains NULL. This causes an Access Violation which escalates into a BugCheck.*
*AFAIK Apple does not distribute driver symbols so I was unable to dig into the cause for the fault in this driver. I am appending some additional crashdump information that might be useful. If you require additional information, let me know. I can either provide you with the full crashdump of perform further analysis if you make the symbols available.*

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.

Kernel panic when resuming from sleep

I've been getting random kernel panics on my MacBook Pro when resuming from sleep. That is, only when resuming from sleep - otherwise the computer is fine.
I read some other discussions on here regarding kernel panics, but it seems that an inspection of the panic.log file usually uncovered a bad USB driver or something of that nature. I have no extra peripherals on my machine, and the panic.log is fairly vanilla. In fact, every entry in the log looks like this:

Yes, every log entry ends with that "invalid frame pointer 0xbffff358" bit.
The only thing I can surmise is that the memory (factory installed) is faulty, given that the frame pointer address is always the same.
Can anyone shed some light on this i.e. does this sound like I'm on the right track?

AH HA ! Then yes the combo updater is a good first step. It's not the same as applying all the smaller updates as they come out, using this ensures that every aspect of the OS is current. Before and after you use it, Repair Permissions ...

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!

P35 - CPU fan reset when resumed from sleep

Hi,
I just got S3 sleep to work where it turns off all fans. The problem is that when it resumes from sleep, the CPU fan spins a lot faster than from boot. I've set it to run at 12,5 % as long as temps are under 65c. I'm guessing it runs at about 50 % when resuming from sleep. It does this until I restart the computer.
Tips?
/Edit; Just checked with SpeedFan, CPU fan normally runs at 1100 RPM, but after resume it runs at 1800 RPM. Any utility I can use that resets this to 1100 after resume?

I ended up disabling fan control in BIOS, so that SpeedFan would work in OS. This means that CPU fan runs at 100 % until OS and SpeedFan har loaded up. Tips to fix this through BIOS or whatever are welcome.
