Thinkpad T420 Intermittent Freezing / Lockup

Thinkpad T420 Intermittent Freezing / Lockup
My Thinkpad T420 keeps intermittently permanently freezing / locking up. However it seems that anything that uses hardware acceleration makes the system suddenly lockup. For instance, boot into Windows 7 and open Chrome Browser play a YouTube Video and it will lock up or enable the Windows Areo Theme and try looking at the event manager will also make the system permanently lock-up.
Here is the troubleshooting that I have tried so far:
Fresh OS installation from the recovery partition and update using Lenovo System Recovery but problem still persists. ( includes updated BIOS )
Run Lenovo Diagnostics ( 20 times pass over ) and no fault reported. ( no test in Diagnostics for CPU Graphics )
Tried a known good harddrive and loaded Windows 7 and applied Lenovo System update and problem still persists.
Tried using a known good memory module ( Lenovo T420 memory module ) tested separately in each memory bank, the problem still persists.
Used the machine with out the Battery, using just power cord and problem persisted.
Used the machine with just the battery and the problem still persisted.
Using the machine with Battery connected plus power adapter and problem persists.
Removed the DVD drive and the problem persisted.
Removed the Wifi Card and the problem still persisted.
Removed the 3GS card and problem still persisted.
Swapped over another keyboard from another Thinkpad T420 and problem still persists.
Disabled Fingerprint reader in BIOS and problem still persists.
Confirmed no freezes if Thinkpad is booted into the BIOS and left for some hours.
Booted machine with a live Linux Mint 16 DVD and problem still persists ( Freezes straight away )
No freezing when the laptop is used in Windows 7safemode.
No freezing when the laptop is used with Linux Mint in safe mode though Mint does confirm that hardware acceleration has been disabled.
CPU tempertures are within the normal range.
The troubleshooting confirms that the problem is a hardware fault. So I logged a warranty call and explained that it was likely a fault with the System Board or the CPU. The engineer replaced the system board and the problem still remained.
So it look most likely that the integrated graphics seem to be causing the problem, especially when the system freezes when hardware acceleration is used. Has anyone else had a similar problem. I'm now waiting for the next plan of action form Lenovo. I did confirm the system freezing problem with Windows 7 and Mint 16 after the engineer replaced the system board and before he left. I'm still waiting on Lenovo getting back.

I done extensive testing, it was not the hard drive. It turned out that the integrated graphics on the cpu were faulty. The CPU has since been replaced and the problem solved. As per my first post, anything that used hardware acceleration would cause the freeze hence my suspicion about it being the cpu or planer board. It would freeze in windows and when using a live mint Linux cd, so the mint live cd ruled out the hard drive and preloaded software on it.
Thanks,

MacPro3,1/10.8.2 intermittent freezes multiple times a day

For the last two weeks my MacPro 3,1 has been experiencing three to five intermittent freezes per day. The last couple of days I have experienced nearly one an hour.
I have not been able to peg it to any specific system update, application or hardware issue. There are no kernel panics in relation to this issue. This MacPro originally started with a fresh install of 10.6.x, and has been a stable system through all OS updates, up to and including 10.8.2.
The freezes have occurred with various programs running: (only) Finder, various elements of CS6, iTunes, Mail, Terminal, Activity Monitor, etc. iTunes will continue to play music. Activity Monitor will update statistics in graphs for a limited time, while the process monitor responds for a longer time. After a freeze I have mouse control and can click between on-screen windows and applications. The menu is non-responsive. I will occasionally get the beach ball of death. The only recovery is a hard power down and reboot.
In attempting to diagnose the problem, I have experienced similar freezes with a fresh install of 10.8.x with no 3rd-party software on a temporary partition. This led me to believe I had a hardware problem. I pulled and reseated all RAM, the four hard drives and SSD, the video cards. I ran SoftRAID's non-destructive verify on all four of the Samsung HDs, which then predicted a potential problem based on one of the drive's SMART data. I then backed up the data located on the RAID and did a three-pass certify-level test on the suspect HD with SoftRAID, which cleared the drive of errors.
Any ideas are greatly welcome. I have included the system information and one system log from this evening while attempting to copy files from an external drive to the RAID.
Thanks much!
Tom

Ah, the "20 Questions" - mention m4 and would have said to check you have the latest firmware. Common enough that after way too long lengthy threads to get to the bottom.
Even Zero all does not rule out bad sectors all the time, but it does insure the headers are good when you format a drive or setup an array. I thought the latest SoftRAID 4.x scanned in the background during idle time AND it reports disk I/O retries (bad is a bad work, 'weak sectors' is probably more accurate: is 5 retries bad or is 10?). Is not a 100% black/white issue.
Firmware is hardware and heck, OWCs own SSD controller is throwing out a bunch of corruption issues too.
iTunes use to be good at detecting weak/bad RAM. AHT isn't. Memtest may not (especially with ECC) and DIMMs also have firmware, SPD code and variations.
SSDs though with the constant improvements and change have been popular issue. In May-June a bug in the latest SandForce controller firmware that took a long while to get to the bottom.
Odd that Crucial doesn't say more or the comments section on Newegg and Amazon don't have more?

Thinkpad T420 with Optimus: Card is turning on at random

Hey yall,
I'm using bumblebeed on my Thinkpad T420 and upgraded to bbswitch for power management. The discrete card still shows up in lspci when it's 'turned off" but power consumption goes down and bumblebee says its off, so I figure that's the best I'm gonna get.
Weird thing is, it keeps turning itself on for no good reason. I manually switch the daemon on and off, which I thought was completely controlling all software interface with the card. Apparently ACPI is turning the card on for some reason, and I don't want it to. The only reason I noticed is because I was watching the logs to figure out unrelated ACPI behavior. Pasted below is when I unplugged the laptop and plugged it back in a couple times to see what happened. About a minute later, ACPI wakes up the card. The stuff after that is me running a script that cycles the daemon, which is the most consistent way I have to disable the card manually. I think I pressed a laptop button in there somewhere too.
Does anyone know why ACPI might be waking up the card at random, and how to get it to stop? I have a feeling it's eating away at my battery without my knowledge by turning itself on when I'm on the road.

Ok, so, apparently it is turning itself on when I'm using Flash. I am scratching my head. My browser should have no idea that card exists, because I use optirun to select things to run in that layer. And the bumblebee daemon is off. This seems like a security issue! I'm only able to control the card with root privileges; how on earth is Flash getting around that?
Any ideas are welcome, this is a little over my head. I don't understand ACPI in any intimate way.

Thinkpad T420, Integrated Graphics, Dual Monitors

Warning: this isn't really a problem thread. I've looked and looked but can't find a definitive answer for my question.
I'm seriously considering a Thinkpad T420 for a new work laptop. I've heard great things from many people, but the most important question has yet to be answered: if I get one with integrated graphics (Intel HD 3000), will dual monitors work with VGA and DisplayPort with a DVI adapter? It's crucial that I'm able to use two external monitors simultaneously and I'm sick of using TwinView because I can't rotate a monitor. Can anyone confirm that this works?

according to tabook.pdf
Intel HD Graphics 3000 in processor,
external analog monitor support via VGA DB-15 connector and
digital monitor support via DisplayPort (supports single-link DVI-D via cable 45J7915);
supports dual independent display;
Maximum external resolution: 2560x1600 (DisplayPort)@60Hz;
2048x1536 (VGA)@75Hz; 1920x1200@60Hz (single-link DVI-D via cable 45J7915)
So, it looks like the hardware is certainly capable of it.

My thinkpad t420s doesn't last 2 hours

hardware and software:
* thinkpad t420s, brand new with standard battery
* CPU: i7-2640M CPU @ 2.80GHz, 4 cores. frequency scaling is enabled, they all usually run at 800MHz (ondemand governor)
* intel SSD, no HDD
* wifi: iwlwifi: Intel(R) Centrino(R) Advanced-N 6205 AGN, REV=0xB0
* thinkfan is installed, but couldn't get it configured properly. TODO
* kernel args
[dieter@dieter-t420s ~]$ cat /proc/cmdline
BOOT_IMAGE=/vmlinuz-linux root=/dev/mapper/cryptpool-root ro root=/dev/mapper/cryptpool-root cryptdevice=/dev/sda3:sda3crypt:allow-discards ro add_efi_memmap i915.modeset=1 i915.i915_enable_rc6=1 i915.i915_enable_fbc=1 i915.lvds_downclock=1 pcie_aspm=force quiet quiet add_efi_memmap
bios options:
* graphics is set to optimus (though i don't have bumblebee/optimus enabled right now, I haven't needed to attach an external display). TODO force "built-in GPU" in bios, maybe that helps.
* intel speedstep set to optimal battery usage when not on AC
* adaptive thermal management set to "balanced" (it's that or performance)
* cpu power management enabled
* pci-e power management enabled
test:with some basic usage (say 40 min of browsing over wifi and watching some vids, and the rest idle) it doesn't last 2 hours. (about 1h50min)
although I think I have all the most important things taken care of, I'll also have a look at https://bbs.archlinux.org/viewtopic.php?id=134109 and maybe laptop mode tools (I did look at it, but as i don't have a HDD and i have frequency scaling already enabled...)
I'll also need to try some power diagnostic tools like powertop or whatever it was.
any more tips? this is kindof disappointing, I was expecting 4-5-6 hours.. thanks!

I have a T420 (didn't want to bother with the dedicated GPU) and get 6+ hours. I followed the steps on 'Laptop' on the wiki, installed tp_smapi, thinkfan, granola, etc.
i also had trouble getting thinkfan to work. The trick I found with it is to stop the daemon and launch it manually (with the -n flag, as shown in the rc.d daemon script) to see what it complains about. After a few iterations to thinkfan.conf the daemon seemed to start without problem. This thread (found on the thinkwiki AUR page) helped me the most: http://ubuntuforums.org/showthread.php?t=1749186&page=1.
thanks, so what's your thinkfan config?
Here it is. Hope this is helpful. You'll probably need to run that find command and replace the four lines which start with "sensor".

Intermittent freezes upon cold boot

Greetings gurus,
I've been experiencing intermittent freezes on cold boot since a few weeks. I did not have them on 10.5.4. I've only had 4 freezes and according to the CrashReporter log all are identical, as far as I can tell. I have not installed any new hardware and I have only one external thing connected and that's a Sennheiser USB headset. I'm unable to tell if all leave identical messages in other logs however.
The *CrashReporter log* for the four occasions says that the process which broke is *coreservicesd [43]*. On each occasion, it is said that "Thread 0" crashed. This is how the beginning of that log reads (from the crash earlier today):
*Process: coreservicesd [43]*
*Path: /System/Library/CoreServices/coreservicesd*
*Identifier: coreservicesd*
*Version: ??? (???)*
*Code Type: X86 (Native)*
*Parent Process: launchd [1]*
*Date/Time: 2009-01-19 20:33:26.618 +0100*
*OS Version: Mac OS X 10.5.5 (9F33)*
*Report Version: 6*
*Exception Type: EXCBADACCESS (SIGBUS)*
*Exception Codes: KERNPROTECTIONFAILURE at 0x0000000000000000*
*Crashed Thread: 0*
The symptoms are:
+ *Menu bar* is invisible (can make out language flag, airport and bluetooth icons and bottom of menu bar).
+ Finder is unresponsive (can't open folders on the desktop and their icons are gone but not their names - relaunching the Finder does not help).
+ Applications won't launch from the Dock.
+ I can access the Restart, Sleep, Shutdown dialog box by pressing the off button on my ACD, but the Shutdown button doesn't work.
+ Holding the power button will not always force shutdown, but seems to put the computer in some sort of sleep mode (when pressing the button again the desktop will appear "greyed" out and a white progress bar will display).
As it doesn't happen upon every cold boot I haven't been able to use the Verbose mode. I have done the following:
+ Trashed the plists of Finder and Dock
+ Fixed permissions in DU
+ Left it unplugged from the mains for a whole day
+ Reset PRAM/NVRAM
+ Using Onyx, deleted the caches under Cleaning - System and Cleaning - User (radical perhaps?)
+ Turned off all login items (AppTrap, Gmail Notifr, Fuzzy Clock, Skype)
+ Run Apple Hardware Test, normal and extended, with no errors found
+ Verified boot disk in DU while booted from the installation disk: no errors
I tried a Safe Boot but it froze. However, it does not freeze every time.
When it froze this evening, I found loads of the following message in Console-All Messages:
*WindowServer[51] LaunchServices/5123589: coreservicesd is running an unsupported version, 0 ( we are 10500000 ), so we cannot talk to it.*
Many of them are prefaced by loginwindow[23] instead of WindowsServer.
Below are the messages in Console-Console messages from the latest time that it froze (all of the messages). There's some talk about com.apple.UserEventAgent-Aqua which I don't understand.
When it says that a "thread" crashes, could it be hardware-related (i.e. the processors)? But should not AHT have caught that? Or is it some corruption in the system? I have backups and clones so I'm not worried about losing data. I'm more concerned about the hardware.
Any thoughts and ideas would be helpful.

Actually, doing the following would probably fix everything; at least it has fixed every issue I have ever had.
If Disk Utility can't fix it, you'll need a more robust utility for the repair. I would recommend DiskWarrior. It is the best at directory repairs. It rebuilds then actually replaces your old directory. I feel every Mac owner should have a copy. Make sure you get the disk so you can boot up on it to run repairs. You can also install it on another drive and run it from there to repair this one. DW works faster that way.
I use DW once a month to try and catch errors in my system from getting too far out of hand.
If you have a good backup, hopefully a clone of your system before you had issues, an Erase and Install may also rid you of this issue. But, beware! You will lose everything on the drive with this procedure. Let us know if you need help with that!
 Luck! DALE
p.s. by Thomas Bryant '''' from a previous post.
Diskwarrior is a "must have" utility and it's corrected any weird problem I've ever encountered. Anytime I have to do a forced shutdown etc. I run DW to get the directories back in tip top shape. Directory problems cause strange issues and often over the course of several weeks or months the little problems add up to finally a major problem. Tom

HEAT = Intermittent freezing or complete crash requiring a hard reboot

I have a stock Macbook Air 1.6ghz with the hard drive and I'm on my second machine. Both have done the same thing leading me to believe there is a serious defect in the Macbook Air. What happens is that after about a half hour of using the machine and running it with some apps like Parallels, video, whatever, it will get really hot. Especially in the upper left region of the computer. It feels hot to the point that you can't really hold on to it as it's too uncomfortable.
iStat claims the case temperature is: 108 degrees fahrenheit. This is prior to it getting really slow and crashing, since I can't really get to iStat when that happens anyway. The whole process of the Macbook Air getting to this point seems to correlate with using the disk and pushing the CPU. What always seems to be true is that the upper left region of the base of the computer is really hot.
The intermittent freezing is quite annoying as the trackpad will completely become non-responsive and you can't type or do anything. Although if a USB mouse is plugged in you can move that and it will move the mouse cursor on the screen, but clicking or doing anything doesn't work. One time we were in a video chat through iChat and it worked fine for about 20 minutes or so and then suddenly started doing the intermittent freezing. The video and audio would freeze, then it would suddenly come back and play the missed portion in fast forward or just skip it altogether.
So my question is how do we get this fixed, I love my Macbook Air, but being able to actually use it is even more important. The minute I try to do anything more compute intensive it just seems to seize up and die. From my experience and reading about other peoples experiences this appears to be a fundamental defect in the Macbook Air. I would like to actually get some support for this instead of the usual we don't know anything about it and blah, blah. Hopefully Apple will just own up to it and work to quickly fix it.

Yes I've considered what I do on the machine, and no it doesn't matter what I'm doing specifically. What does seem to matter is whether what I'm doing is taxing the machine. If I'm compiling software, running a video, running Parallels with Windows, copying large files, etc. then it will cause the machine to heat up and then start failing. I don't have to do very many things at the same time either, if I watch a video on it and compile some software it will heat it up and cause it to start failing. It seems to be a combination of using the processor and hard drive to where it can't handle things.
Right now for example I'm doing a Macports port install of Apache 2 and then typing this message into Safari. That's it. The machine is right now at 113 degrees F according to iStat. That seems to be the magic temperature where at that level and up it starts failing. It's hot enough that touching it is too uncomfortable. It's sitting on a Targus cool pad, clear open access for the vents below. It's simply not designed properly to handle doing anything that pushes the hardware, in my opinion and from my experience with it. I do really like the form factor though so I wish it did work properly. I'm writing about my experiences with it so hopefully Apple will pick up on what users are experiencing and fix the design of the machine. Clearly it has design issues.
The other thing that bothers me about the Macbook Air is that everyone acts like the users are somehow causing the problem. Things like oh you are blocking the fans and putting it on your lap, or you set it on something that causes it to heat up, or it's the software you are using. Well I've got news for you, these things should work in those environments, it shouldn't be a problem to put the thing on my lap, if I wanted a computer that I could only put on a table or something similar I would have just stuck with my Macbook Pro or bought an iMac. This thing is built to carry around and throw on your lap to get stuff done. At least that's why I wanted it.
I guess for now I'll just have to use it for only 20 - 30 minutes at a time and give it breaks to cool down, ugh!

Intermittent freezes while recording

Hello. While recording with Adobe Audition, there are intermittent freezes. As a result, there are sections in the recording where there is no sound at all. Here is an image of the wave:
http://img177.imageshack.us/img177/548/auditionaf6.jpg
I am using Windows Vista on a laptop w/ a built in microphone. This problem doesnt occur when i use other sound recording programs. I have 2GB of RAM.

Turn off all processes working in the background, such as anti-virus programs, autoupdate programs, Wi-Fi cards, internet access, etc. They are stealing resources from your computer that Audition needs.

Slow launch and intermittent freezing in Windows 8.1

Been trolling through the threads and cannot find a solution. I've also tried the QTMovieWin.dll solution but no change. I've also uninstalled, then went back and deleted all reminants of iTunes related files (incl. Bonjour, iCloud, etc), then re started the computer and re-installing the latest iTunes program (via run as administrator). I've done this several times to date. On each occasion I launch iTunes but it take at least 10minutes for it to launch, and when it is running it intermittently freezes for a couple of minutes or so. Problem is worse when I attach one of my devices, and then becomes a pig of a thing to complete certain tasks.
Has anyone come across this behaviour? As far as I'm aware the drivers are update, but are any specific drivers that I should double check?
Any help would be appreciated.

Hello eycon
Try out the article below to troubleshoot your issue with iTunes freezing on you. Also check to make sure that when you removed iTunes, did you uninstall in the order of the second article as it does make a difference when troubleshooting the issue.

Why is my MacBook Pro 10.6.8 intermittently freezing?

My MacBook Pro 10.6.8 is intermittently freezing, it will last about 60 minutes from start up before it freezes - the freeze typically starts when saving a document.
For example in Pages, error message: ‘-document name- could not be saved’, sometimes continuing ‘...because of Disk Error’. Then the software won’t quit, I try selecting Force Quit and that doesn’t open and then I get the Beach Ball. It has happened in Safari, Mail, Pages, Photoshop and also when I tried to open Disk Utility. On one occasion the words in Finder/Edit changed - 'Undo' was replaced by ME1, 'Redo' ME6 and 'Cut' ME13.
I have repaired permissions, installed latest OSX update and run Applejack. The Mac is early 2008 4GB RAM and has a Crucial SSD installed in Feb this year. I am fully backed up although I don’t have a bootable back up apart from the original OSX disks from ’08.
Would really appreciate any clues.

Hi Dale
26GB remaining (but bear in mind this a Solid State Drive which I'm told doesn't need so much headroom - I've previously run it fine with 12GB remaining).
I have 4GB DDR2 SDRAM
Thanks, Paul

Since I upgraded to Lion, my computer (iMac mid 2010) intermittently freezes.

Since I upgraded to Lion 10.7.3, my computer (iMac mid 2010) intermittently freezes. The mouse moves, but I can't do anything. I can unfreeze it every time by calling up the Force Quit box and then excaping out. I've tried everything (all upgrades installed including firmware, new version of Flash), but it still freezes. Any help is appreciated.

There are a couple of things to do. First is restart in the Recovery Partition and repair Disk Permissions in Disk Utility and Repair the Disk. How you do this is when you hear the startup tone hold down the Option key and choose the Recovery Partition. Choose Disk Utility and Repair Disk Permissions at least twice. Then while you are in DU run Repair Disk twice. Quit Disk Utility and restart however restart in Safe Mode, this will clear some caches, it's possible one or more has become corrupt. After it has fully restarted then restart normally and test.
If you get the same behavior post back to try some other items.
BTW how much Free RAM does the machine have. You can find this out in Activity Monitor which is in Applications - Utilities - Activity Monitor and click the System Memory tab.

Does Thinkpad T420 with Windows 7 home Premium support Windows 10 update

Does the Thinkpad T420 running windows 7 Home Premium support the windows 10 upgrade? Also, my machine is very slow to start (3- 4 minutes). Will the upgrade to windows 10 help this issue?

The T420 is not supported by Lenovo for Win 10. That doesn't mean that it would not mostly work, but it does mean that you will certainly have some 'adventures, along the way, and may find that some things just don't work with Win 10 - whether those things are important few you will depend very much on how you use your T 420.

Droid X2 Owners with Freezes/lockups READ THIS!! and VZ/MOTO employees!!!

I am COMPLETLEY convienced the Freeze/lockup has something to do with the SD card or SD card slot. i retored my phone to 100% stock yesterday, NO bloatware removed etc...ran so nice all day, this morning i decided to put the SD card that came with it back in the phone, formatted it, and BOOM within 15 min, SCreen lock up
MOTO and VZ, you need to look into this. i think that is the issue on the freezes. im going to maybe call and see if i can get a replacement....
**also has happend with a seperate 32 Gig SD card*** SD card slots bad???

Interesting.....if you are running GB, then that's probably your problem. I have had an original DX since Nov 2010 and up until August when they released GB, I had absolutely no problems with the phone. Once GB got installed to the DX, the SD card started having serious issues. The card the phone came with just up and completely corrupted right after GB got installed on the phone, and then the replacement card that I was forced to go buy (VZW refused to replace it but that's an entirely different story) has had problems 3 seperate times since I installed it into the phone since the end of August....seems like every 3-4 weeks the SD card suddenly has file system errors and I cannot read anything on it (computer won't even recognize it), so I end up losing pictures, ringtones and other things to the point that I have regularly back everything up to my computer just to make sure I can keep these pictures and ringtones. They're not all that important pictures, but still....if I was able to go 9 months on Froyo with NO problems with the SD card (or phone for that matter), then how come 2 months since VZW pushed the GB update to the phones are there regular occurences......something is fishy in Denmark with all these sudden problems
I would hope that VZW and Moto would realize the problems increased ten-fold since GB was pushed and actively attempt to fix them once and for all, but I truly believe they view it as the phone being EOL (no NEW phones are sold anymore) that the issues are no longer of a big concern to them. Seems like the only answer is that as we are able to do so, just upgrade to a different phone. I know for a fact that I will NEVER get another Motorola phone.....the DX is a great phone, but Moto, and to an extent VZW, have truly caused the phone to go down the proverbial toilet, which is a shame

Is the ThinkPad T420s available with i7 without getting the NVIDIA graphics?

I'm looking at ordering a Lenovo T420s soon for myself. In both the reseller guide and on the Lenovo CTO site I don't see any configurations of the T420s that are offered with the Core i7 processor but without the NVIDIA Optimus graphics. Is this an available configuration?

Previous: ThinkPad T420s // ThinkPad T410s

Will we be seeing those machines in April? I would be upgrading mine to recycle mine to a new hire. No approval yet, but depending on the timeline I may not have the option of waiting...
I like the look of the T430u but we use docking stations here so that one may not be an option for me. Besides I want a full power laptop because I find iPad fills the ultraportable space for me quite well right now.
