X220 resume from sleep and boot issues

This is driving me crazy! I have an X220 with Windows 8 and UEFI boot installed.
It all started when I first installed Windows 8 a few months ago which required me to update my BIOS to the latest version. The installation process often got stuck when booting from the Installation CD (the round circle stopped spinning, the display was at full brightness). Eventually I managed to boot into the Installer (when the boot logo doesn't get stuck, the display is then dimmed to minimum).
I was quite happy to have a superfast lightweight OS which booted in an instant.. When suddenly it started to get stuck when booting (same issue with the boot logo not spinning anymore). This happens quite randomly, but I often manage to boot (maybe 2-3 times a week, I don't boot often though..). Now, the booting hangs are less of an issue for me but more often that that it fails to resume from sleep. The LEDs flash and then it instantly drops to sleep mode again (well at least the sleep/moon LED is active). This happens quite often as I sleep/resume up to 5-10 times a day (changing lecture rooms, meeting rooms, save battery when the lectures are boring, ...)
Now after researching and spending hours in debugging this issue, it seems that I'm not the only one having this (or a similar) issue, but often without any definitive solution being specified.
This is what I have already tried:
* Upgrade BIOS and SSD firmware to latest
* Install/update latest drivers
* Mess around with BIOS options
** UEFI/Legacy First options
** Intel Virtualization/vt-d
** Others..
I know based on other threads that I'm not the only one experiencing exactly these issues. Has anyone managed to fix this?
Thank's in advance

I had a similar issue, as soon as a described even a little bit of it to warrenty support they sent someone to swap the board
It seems thats the only fix, its been fine since

Windows explorer + other windows applications crashing regularly at resume from sleep and hibernate

Good evening,
I have a Thinkpad W510 (4319-29G) running Windows 7 Pro 64bit. The system is loaded with the latest software and drives from Lenovo including BIOS 6NET74WW (1.34), upgrade was done Dec 7th (windows update performed Dec 15th).
The machine has
- 8Gb RAM
- nVidia Quadro FX880M, driver version is 8.17.12.5896, 7-9-2010 and video card BIOS is 70.16.5f.0.b
- dual harddrives,
- one Seagate Momentus XT 500Gb (ST95005620AS) FW rev SD23 in the main location with C: and some other partitions
- one Hitatchi 320 Gb (HTS723232L9SA60) FW rev FC4ZC50B in the bay.
- Intel Centrino Advanced-N 6200 AGN, driver version 13.3.0.24, 7-14-2010
- Intel 82577LM Gigabit Network Connection, driver version 11.5.10.1030, 7-22-2010
Recently I have experienced crashes of multiple windows components at resume from sleep and hibernate.
It seems to happen when swithing location (from work to home) and thus switching from docking station with wired network connection to no dock and wireless network connection (dont know if this has any bearing but anyway).
In the event viewer I typically have some 6-12 application errors logged. Sample output from event viewer is:

It seems that a module "nview64.dll" is always the first application to crash. I suspect this has something with graphics to do.
I dont know if this event triggers the following crashes or if it is so that the display is initialized before the other programs.
After all crash diagnostic messages have been shown windows explorer restarts and also other applications restart but a lot of system tools in the system tray are gone so a cold start is needed to restore all tools again.
I really would appreciate any help and suggestions how to fix this really annoying issue.
Thanks, Anton

Resume from Sleep / Hibernate issues

Hi all,
First time poster. I have a Helix and am running into a heap of resume from sleep (and hibernate) issues.
The sleep issues tend to happen overnight - I do not have this issue if I sleep the machine and then wake it up 5-10 minutes later (e.g. moving between meetings at work). However, when I attempt to wake the machine up in the morning, it fails to resume from sleep, and instead boots from scratch.
Typically, when the unit is in this state, the status led on the lid is rapidly blinking (which I believe means that it's trying to enter sleep) Since there is nothing in the Windows event log during the overnight period, I'm wondering whether it's trying to enter a deeper sleep mode and failing.
This happens every second day or so. Which is really frustrating as a tend to lose some work.
I tried enabling hibernate as a trial, to see if that would avoid the issue, but resuming from hibernate fails as well. At least I get a Windows event log entry for this (source: kernel-power. The unit fails to resume from hibernate with status 0xC000000D)
I have the September 10 BIOS update, and am running Windows 8.1 Enterprise (though I had the issue with Windows 8 as well).
Any ideas on how I can troubleshoot this?
Regards
AC

Windows 8: In Windows 8, the default shutdown behavior puts the system into hybrid shutdown (S4) and all devices are put into D3. Remote wake from hybrid shutdown (S4) or classic shutdown (S5) is completely unsupported. In Windows 8, NICs are explicitly not armed for wake in both the classic shutdown (S5) and hybrid shutdown (S4) cases because users expect zero power consumption and battery drain in the shutdown state. This behavior removes the possibility of spurious wakes when explicit shutdown was requested. As a result, Wake-On-LAN is only ever supported from sleep (S3) or hibernate (S4) in Windows 8.
Note that in Windows 8, hybrid shutdown (S4) stops user sessions but the contents of kernel sessions are written to hard disk. This enables faster boot.
http://msdn.microsoft.com/en-us/library/windows/desktop/aa373229(v=vs.85).aspx
From the Helix User Guide:
•Slow blinking: The tablet is in sleep mode.
•Fast blinking: The tablet is entering hibernation mode or sleep mode.
That was my reason for clarifying if hybrid-sleep was enabled; since it's the default setting and you noted that the LED was blinking fast. Does the LED ever stop blinking fast?
There can/may be multiple log entries during a normal sleep operation, because "the system uses the lowest-powered sleep state supported by all enabled wake-up devices." If one of those devices wakes the system (this does not mean power on) then the logs will report the devices and will likely return to a another level of sleep, but this does not mean full power loss or empty logs.
If the system has successfully entered sleep state, then you should see the following message in System Event logs.
Event 42, Kernel - Power
This system is entering sleep.
Sleep Reason: Button or lid
When the system is successfully woke you will see a System Event Log similar to this:
Event 1, Power - Troubleshooter
The system has returned from a low power state.
Sleep time: 2013-10-08T01:42:25.XXXXXXXX
Wake time: 2013-10-08T05:53:21.XXXXXXXX
However, there will be other events in the logs after sleep and prior to this wake period, such as hardware device issues(My helix has Bluetooth device warnings, nfc driver warnings and some other nondescript hardware errors), kernel messages (about boot manager, boot options, etc.).
Have you changed the behavior of the power button?
You also can program the power buttons so that by pressing the power button you can shutdown the tablet or put it into sleep or hibernation mode. To achieve this, you need to change your power plan settings. To access power plan settings, do the following:
From the desktop, tap the battery status icon in the Windows notification area.
Tap More power options.
In the navigation panel, tap Choose what the power buttons do
Follow the onscreen instructions to configure settings.
Lastly, when you updated to Windows 8.1, did you format the whole C:\ (mSATA) drive?

X120E Touchpad inoperable after resuming from sleep

hello friends I'm a happy X120E user and a tech [pc's, mac's, lans, etc] - I do all sorts of tasks with my x120e and its been great. I recently "upgraded" my SSD so a fresh new install of Windows 7 was in order. After updating everything I have a problem I did not experience previously at all - not once in 3 years of use.
Upon resuming from sleep [and as far as I can remember this only occurs when resuming on battery], the touchpad/cursor is inoperable, frozen in the centered position, and I have found no way to 'wake' it. I finally have to shutdown/restart to get things functioning again. Keyboard works fine, but not touchpad or trackpoint [either/both].
maddeningly, its not consistent in this. sometimes it works, sometimes it does not.
I have seen the same issue with, and without, the supplied Lenovo Ultranav driver installed.
Question: in the X120E implementation, is the touchpad a PCI bus device or a USB device? I see no power plan options [i.e. "Advanced" >"Allow this device to wake the computer"] available via Device properties. There are no pointer/mouse/touchpad options whatsoever under Power Plan Settings.
Will Fn+F8 enable/disable the touchpad on this notebook? or,... should it?

No. Powering off and on again didn't work. My drive is a Seagate 750GB internal SATA drive in a Vantec NexStar-3 external enclosure. I don't think it is a driver issue. After the device removal error it won't mount on my PC or my Mac via FireWire or USB.
What I need to know is if there is some way to connect to the drive and make it mount with other software, using some kind of keystroke during startup, or maybe through terminal or something. I can't even try to repair the drive because it won't show up in disk utility.

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.

Upon resuming from sleep, the monitor goes black

the laptop is actually booting, but the screen flashes on for a sec then goes dark. I can still see the screen and icon to log in, but the backlight is out, and I cannot log in actually. if I close the lid and wait then open it again, it does it again. I takes sometimes 5 times for it to finally stay lit and work again. This also happens if I do a hard boot, sometimes taking up to 8 times with a hard boot. I thought it might be related to the OS so I installed a partition and installed windows but it happens the same to windows. It never goes out when I am working on it, only if I let it go to sleep or power it off and then try to resume or turn back on. Any ideas?

Fix - *Dont give your iMac a static IP*
go to your Main or First routers settings and Give the iMac a SET IP so that it never changes. Then renew your DHCP lease and that set IP will come up and stay there. FOREVER!
I just resumed from sleep and it is not doing it anymore.

My Mountain Lion mac crashes after resuming from sleep

Hello
My Mountain Lion mac crashes after resuming from sleep every time I use it
It happens every time the mac resumes from sleep and it started like a week ago
I remember installing the new updates for flash? and xquartz and nothing else.
I have also had microsoft word installed on my mac for about 1 weeks before this problem started so might be related to that
Please share with me any tips on how to fix this because I am really annoyed of losing stuff after each time my mac resumes from sleep

I have an iMac bought may -11, and it worked fine with Snow Leopard.
About a week ago I bought and installed Mountain Lion 10.8.2. Everything went fine, and all software worked ok. iPhoto had some problems, but after installing update the system prompted to do, it has worked ok.
The propblem occurs now and then, when computer is waked up from sleep. The Desktop occurs, but no software starts, not even System Tools untlil rebooting the computer. Of course, I can not reboot the computer from "Apple menu", but holding the power button down.
This is very embarassing! OsX Mountain Lion has turned out to be a very big disappointment. I installed id because of iCloud (i have a new iPad, too with iOs 6 installed).
Can anyone help me? Is there any other way to solve the problem than re-installing good old Snow Leopard?
I would not like to do that, I bought Mac because I was bored in re-installing and recovering!
Thank you

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.

Windows 10 Resume from Sleep Very Slow

Completed the upgrade to Windows 10. Machine is now very slow to wake from sleep. Full resume takes about 2 minutes. When resume starts, touchpad lights up but screen stays black. It seems that the machine is going through some type of process that takes long. I noticed that the graphics drivers for AMD were updated. I tried to reinstall the old AMD drivers but the install failed. Could the graphics drivers be causing the problem? What other drivers that might have been updated could cause the problem?

Later news! The problem driver was the AMD Radeon 6700M series ver 15.200.1062.1003. The slow resume from sleep and similar delay in startup was resolved by disabling ULPS. See this URL in the AMD community forum https://community.amd.com/thread/184727

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.

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.

I7 iMac with Bootcamp 3.1 and Windows7 64-bit won't resume from sleep

When I try to resume from sleep, by clicking the magic mouse button, the screen comes up and I can move the mouse around but the bluetooth keyboard does not work and I can't launch any programs. Have to use the rear button to force a power off and restart.
Is anyone able to resume from sleep okay and carry on using Windows 7? If so, any tips? Thanks in advance, very frustrating.

I don't have an iMac, and it seems those have some design "issues" to say the least. I'd say yes, motherboard and/or firmware (UEFI or SMC, or both) could be buggy and at fault.
Other than resetting SMC and running Apple Hardware Test, not sure what else or next to try.
I've seen a number of BIOS updates out in the last months for my PC motherboards that have definitely improved sleep, S3, hibernation - EVGA, Gigabytes, and Intel - all X58 vs P55 (Lynnfield Core i5/7 LGA 1156) the iMac uses.

First I switched to Windows Vista/7, then I switched to build-my-own and custom parts. Love the looks of iMac, came close at one point, but I prefer the specs, options, and configure for my own needs in hard drives, graphics over cool factors.
The iMac even in 2008 when it came with Penryn 64-bit processors never got 64-bit Vista/Boot Camp drivers, and that was why I didn't buy iMac back then, just lack of support I guess, and not seeing the market and need (for a good solid Windows desktop machine by Apple).

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!

GTX660 Twin Frozr 3 OC and resume from sleep problem

Hi,
My 660 twin frozr performs perfectly in game/bench and standard operation but I get consistent error messages when resuming from sleep 'hybrid, S3).
Messages are : either "the graphic driver did not respond and has recovered" or a BSOD "driver verifier has detected violation" or "DPC watchdog violation"
My system :
-Windows 8 64bits
-MSI 660 TF3 OC at stock speed
-MB: Gigabyte H77N WiFi, BIOS F2 then F3C
-i5 3470 at stock speed
-RAM: 2x4GB Crucial ballistic tactical low profile 12800 (XMP profile 1 at 1600MHz 1.35V), OK for hours at memtest86
-PSU: Seasonic G-360. 360W seem low power but 12V single rail is 30A and it powers my system at full load flawlessly (OCCT, game, unigine bench and so on)
What I have tried :
-reinstall windows 8, MB drivers (chipset, WiFi...)
-updated the bios from F2 to latest (but beta) F3C
-nvidia 310.90whql, then 314.07whql (using driver fusion for cleaning)
The resume from sleep issue is still there
Then I tried:
-the 660 TF in a old core2duo with a MSI P35neo MB and vista 32bits. It resumes with the notification "the driver did not respond and has recovered successfully. nvlddmkm..." No BSOD but got this notification each time
-then I tried the old ATI HD4670 in my new PC and the resume/sleep works like a charm.

OK, I had to make a bootable USB drive with DOS because nvflash is not 64bits compatible.
My S/N is 602-v287-050B1212022370 (checked on the box).

No video when using external monitor and resuming from sleep.

I know some people were having problems with the new MacBooks, but I guess the Mac driver fixed something. However, when I'm in Windows and have my Dell 24" hooked up to the Mini DisplayPort -> DVI adapter, I cannot resume from sleep. The monitor will turn on, but I can't get an image on it.
In MacOS it seems to resume from sleep fine, but not in Windows. Anyone else seeing this?
Thanks!

Is no one else getting this error? Does anyone have any issues when their MacBook is hooked up to an external monitor and it goes to sleep?

Update to 10.6.8 - system hang (mouse issue) after resume from sleep

I am on older
MacBook Pro3.1
Intel Core 2 Duo
2.6GHz
Run on 10.6.8 almost flawelessly. Shortly after upgrade to 10.6.8 system started to hang periodically after resuming from sleep. Symptoms are that it stops responding to mouse (be it touch pad or USB mouse). Keyboard seems to be ok but system doesn't seem to be fully functional. I am able to ssh from the other computer and 'shutdown -r now' after reboot system seem to be ok until next resume from sleep. What interesting though is that this problem newer manifests then I am using external monitor.

Found problem. It was due to magic mouse that I left on. I carry this mouse in the laptop bag but rarely use it. Last time I used it (around the same time I install the update) I left it on in the bag. It was apparently disconnecting/connecting on its own and by some reason sometimes was breaking touch pad and other usb mouse connected to laptop, as soon as I switched magic mouse off broblem was fixed
