IRQL_not_Less_Or_Equal T400

We're getting a very strange problem on any T400 we try something on. Alot of our users have 3G dongles that they use. The dongle in question is an E170 HSPA model.
When we insert the BT dongle to the machine, a piece of software installs itself which is needed for the dongle to work, called BT Access manager. The installation works fine. Now, after installation the software boots up and at the point of connection we get this issue on BSOD.
"A problem has been detected and is shutting down your computer to prevent further damage"

***Stop: 0x000000A (0x00453041, 0x00000016, 0x00000000, 0x804F8A68)'
I have done the following in no particular order.
Defrag on C:
System Restore to three seperate points
Lenovo Restore and Recovery
Complete reinstallation of Windows XP SP3 and completely up to date patches and updates.
Every driver in existence for the BT dongle
Changed drivers for the internal network card. (new and old)
Changed drivers for the wireless adapter (New and old)
I am currently doing an SFC check as a last resort. I have spoken to BT about the issue to see if it's something they're aware of, however this is the first instance they've heard of. I have also logged a call with Lenovo however they're being particularly useless on a number of calls so I've given in on that.
I have installed this on a number of others laptops, namelt HP's and Dells with no errors or issues at all.
Does anyone have any advice at all about this as we're currently upgrading all of our users to these T400's and the majority of them will be using these dongles.
Many thanks in advance

I'm assuming you've tried the basics here, but just in case make sure:
1. You're running the latest service pack/essential updates - I am indeed yes.
2. You have the latest driver versions for your 3G dongle and that they are the correct version for the installed OS - I have tried all the Win2k and XP drivers for this dongle yes.
That out of the way, I could use a bit more information.
1. How many T400 systems have you tried this on? - We have seen this problem on 4 machines.
2. Where those systems in a factory-install state when you tried it? - I have the same issue when on factory install state, with Windows XP SP3 w/ updates, and with our own image.
2a. If not, are you able to try the dongle on one in a factory-install state? - Have tried this in configured and unconfigured with the same error.
3. Is it always the same error across the different T400s? - Exactly the same error yes.
3b. If not, please post 2 or 3 so I can see the differences.
4. Does the error message always change when you run SFC? - No, the errors now seem to be sporadic as to which one we get. Either I am now getting the initial IRQL error or I am getting the second STOP error.
Also, if you could provide the memory dumps and error logs for the systems on which this is occuring it would be a great help.
It took me a while as Windows Debugging Tool was being typically troublesome for me.

T400 windows 7, blue screen memory_management and IRQL_NOT_LESS_OR_EQUAL

Hi can anybody help me solving this problem? I have T400 with windows vista 32. I upgraded it into windows 7. And now my laptop is having problem with the blue screen when the windows started it says about memory management or IRQL that asked me to disable the BIOS memory such as caching or shadowing.... What do you guys reckon?? Cheers.

I used to get that BLUE SCREEN ALL THE TIME
I stoped getting it one after I slipstreamed windows xp pro to sp1 and did a clean install
I use latest nvidia http://www.nvidia.com
I use the latest via drivers http://www.via.com.tw
also you should check to make sure your video card is seated properly take it out and put it back in
clear cmos/bios
check your memory make sure it's seated properly also try moving it around I found that the middle slot was bad on my board but I have a K7T266 pro2 v2 thank god I have a three year warenty still time to rma when every I get around to upgrade

T400S IRQL_Not_Less_Or_Equal

Welcome to lenovo user forums
You can use the System File Checker tool (SFC.exe) to check and fix system corrupted files.  To do this, follow these steps:
1.       Open an elevated command prompt. To do this, click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator. If you are prompted for an administrator password or for a confirmation, type the password, or click Allow.
2.       Type the following command, and then press ENTER:
sfc /scannow
The sfc /scannow command scans all protected system files and replaces incorrect versions with correct Microsoft versions.

T400 beeping WHILE sleeping - how to disable?

My T400 goes to asleep and beeps a couple times every 5 minutes or so.
Example:
5 minutes
beep...30 secs...beep...30 secs....beep...30 sec.....beep
5 minutes
Everything else is fine, it doesn't freeze or anything, resumes perfectly. The beeping started after I upgraded all the drivers including BIOS (I was getting BSOD with IRQL_NOT_LESS_OR_EQUAL errors - but updating drivers seems to have taking care of that issue).
Thanks.

Complete WAG: do things like low battery alarm function while asleep? If so, is your low battery threshold set way high?

Memory speed on T400

I have 2 ea. 2gb DDR3 PC-8500 1066Mhz memory modules installed in my T400. If I check the modules under Everest Ultimate 460 they read DDR2 running at 667 Mhz. If I use CPU-Z they also read DDR2 but don't show a speed. Has anyone else been able to check the speed of their modules and what program did you use? I don't see anything in the bios to cause the memory to run slower than rated. Do you think they are really running at 1066 MHz or do I have some type of compatibility problem. I get the same reading if I pull one of the modules out and check them one at a time.

Short answer, yes, the DDR3 memory bus in your T400/T500 should show at 533mhz(+/- 1mhz)
CPU-Z 1.51 will properly show as DDR3, previous versions may have incorrectly shown as DDR2
Here are your answers explianed in detail:

Terrible customer service after systemboard on T400 died for no apparent reason.

So I hate for my first post to be a negative one, but here goes.
I'm sorry if my actions sound rude or impatient, but I'm sure some of you understand the aggravation and worry that accompanies a computer that suddenly stops working when it is needed.
Warning... here's the abridged version, it will still be long. I have also attached a email I sent to Lenovo websales... it has not gotten a response. So far I have not received parts that were supposed to be shipped. I have been hung up on. I have been interrupted. I have been ignored. I have been told that if I want my product fixed I should upgrade my current existing warranty to an on-site service.
I bought a T400 roughly six months ago. I had minor issues with the sound cutting in and out after waking up from sleep since new. I figured it was probably a driver issue. Never bothered to try and fix it, it wasn't a big deal. Other than that, I loved my T400 and recommended that everybody check out Lenovo if they're in the market for a new laptop. Well... no more. I recently put my T400 to sleep. Left it on my desk and walked away. I came back about 20 minutes later, noticed that all the indicator lights were not lit. Strange... okay. I tried to start it. Nothing. I did a search on google, came up with the procedure to press the buttons to drain the system board. Nothing. Oh no. I immediately call Lenovo since I was going to be returning to classes soon. The phone conversations I had with Lenovo techs were less than stellar. One tech told me he could not ship out the box since the system was down... but he somehow managed to look up my serial number, input my information, and issue a case number. Well... turns out he also closed that case. Since he couldn't ship out a box, I brought it to a local authorized warranty service center. They told me it would be no problem. I dropped it off first thing in the morning, several hours later, a tech had called to tell me that the systemboard was dead (what I thought) and that he had already placed the order with Lenovo and that the part was in stock and should be in the next day. I wait two days and did not hear anything. I call the shop. They call Lenovo. Apparently the part is now backordered and there is no ETA on when it may be back in stock. They said I should pick up my laptop and send it in. So I pick up my laptop and call Lenovo to try and obtain a box. I spoke to one gentlman who seems to empathize with me. He wanted to speak to a supervisor to see if he could have the case elevated. I was put on hold... several minutes later, I was somehow transferred to another tech. This guy had no idea what was going on, he was less than helpful, and he did not seem to be interested in helping me at all. I finally convinced him to ship me a box. When I got off the phone, I realized I should try and obtain some sort of time frame. I called back. Some women picked up. I explained my situation once again. She told me the part was in stock (not what the store and 2 techs had just told me). So I asked if it could be shipped to the store? "Uh... Well..." *Click* She either hung up or we got disconnected. I waited several minutes for a call back. There was none. So I called again... This employee told me that the part does not have an ETA and he has no idea when it might be back in stock. This gentleman is a little pushy and interupts me a few times, but for the most part seems to want to try and help. I was told that Lenovo would keep my laptop for an indefinite period of time until the part is no longer backordered. That's not what I want to hear. I need my laptop for school and research projects. He tells me that if I want to get my laptop fixed in a timely manner, I should upgrade my warranty service to a better one. This raises flags. Is Lenovo just trying to pocket more of my money? Shouldn't the standard warranty cover this? So I decide to email Lenovo and see if they can shed any light on the situation and offer any alternatives. I have tried twice since last week and gotten no response.
Here's the email I sent.
To whom it may concern:
My name is William Xiao. I purchased a Lenovo Thinkpad t400 roughly 6 months ago. The deciding factors in this purchase were all the things I had heard about Thinkpad's excellent reliability, durability, and the outstanding customer service. Unfortunately, none of these have been true in my experience thus far. I had recently put the laptop to sleep. When I came back twenty minutes later, none of the indicator lights were illuminated. The system would not power up. I performed all of the procedures offered by the technical support to completely drain/power down the system board. This did not rectify the situation. When I did call technical support, I do not feel that I was treated with respect. One time I called, the employee was very unenthusiastic to help. The technician was very rude. He frequently interrupted me and did not listen to what I had to say. I asked him to ship a box out. He told me he could not (or would not) do that. He told me to call back the next day with the case number to get somebody else to ship out a box. Or to take it to a repair center. I decided to take it to a local repair center first thing the next morning (Jan 5, 2010). The center assured me that the repair would take no longer than 3 or 4 days. Several days later (Jan 7, 2010), I called to check on the status of the repair. Apparently the system board that was needed was in stock when they ordered it, but became backordered with no ETA on when it might become available again. Unfortunately, I am leaving town to return to college on January 11. The shop suggested that I pick up my laptop and have it shipped to Lenovo. I called Lenovo the evening of January 7th. The first person I spoke to seemed knowledgeable and empathetic to my situation. He looked up the part and said it was out of stock at their depot. I explained to him that I would be returning to school soon and needed my laptop for classes and my research projects. He put me on hold while he went and spoke to a supervisor about escalating the case. For one reason or another, I was transferred to another employee who was not a supervisor. This employee was absolutely clueless about what was going on. His attitude was very poor. He told me that the original case that was opened had been closed on Jan 4 or 5. I had not asked for this case to be closed. When I asked him to to ship a box, he seemed somewhat reluctant to do so. He seemed frustrated when I asked him to have it shipped to a different address. As I said, I would be returning to my school over 200 miles away. I would no longer be able to have the box shipped to my home where I was over winter break. For whatever reason, this employee just did not seem to understand that. I asked if the parts were not in stock, how long would it take to get them in stock and get my laptop repaired. He could offer no answer. I asked him if there was any way this case could be escalated since I cannot be without a computer at school. He told me no. I do not feel that I was treated very respectfully. He told me to call some other department. I asked if I could be transferred. He very reluctantly did so. The other department was closed for the night. I called back to the technical service center in Atlanta, Georgia. This time I spoke to a woman. She told me the parts ARE in stock. I asked if they are in stock, can they be shipped to the store where I was having my computer repaired at. She said "Uh... Well..." and then she either hung up on me or I was disconnected. I waited several minutes for a call back. None was ever received. Thus far, I have been extremely unsatisfied with the customer service that has been offered. I asked if there was any way that a temporary unit could be offered while mine was being repaired since I was told that my laptop would be kept for an indefinite period of time while waiting for the part become available again. Or I asked if they could pull a T400 from the shelves, take the system board out, and use that system board to repair mine. I was interrupted and told no. This seemed to be a common theme: interrupt the customer, do not know what is going on, tell them no to any sort of request. It is interesting that the recording on the telephone says how much Lenovo values customer satisfaction. Well, I am not satisfied at all. This computer is still under warranty. It should not be my responsibility to drive to and from service centers to try and obtain repair. It should not be my responsibility to have to call back whenever somebody decides they do not want to perform a task at that time. Lenovo should be repairing my computer in a timely manner. I was told that if I wanted my computer repaired in a timely manner, I should upgrade my current warranty to a on-site service. I feel that they should be doing whatever is possible in order to best serve the customer. It looks like Lenovo is more concerned with making a fast buck. A computer is very important to my education, as I said, I need it for both classes and research projects. Based on the quality of the product and the customer service that has been offered, I will not be buying any Lenovo product in the future. I was strongly considering purchasing a Edge for both my girlfriend and my mother. And I had previously recommended many people to buy Lenovo after I initially purchased mine. But that is no longer the case. Not only will I likely not be purchasing another Lenovo product, I will warn all of the people I know who are in the market for a new computer to look somewhere else. I really want to like and enjoy my Thinkpad, it is very unfortunate that I cannot and that Lenovo will not do what is necessary to make things right again.
Your very unsatisfied consumer,
William Xiao
Any ideas? Any other email addressed I might be able to reach somebody at?
Thanks for reading that mess. I appreciate any input that this forum may have to offer.

As I said (in my overly long post), I had already brought it to a reputable local warranty service center (still about a half hour to forty minute drive each way) after an employee refused to ship out a box (supposedly the system was down, but he looked up my information and was able to both open and close a case without telling me that he was closing it, he told me to call back about it later) because the turnaround time SHOULD have been faster. I was quoted a 3 day turnaround time, 4 days MAX. I dropped it off first thing the morning after I spoke to somebody at Lenovo. Tech took a look at it later that day, before noon, put the order in, called me to let me know that he ordered the part and that it was in stock. He tells me that generally they receive the part the next day. I hadn't heard from the shop in 2 days. So I call. They call Lenovo, part is now on backorder. That's why they told me to ship it. Now I'm dealing with this headache.
I should not have to spend this much time trying to obtain a warranty. The staff has been rude, unhelpful, and uninspiring.
If something is not done to rectify this situation... at least some sort of apology or attempt to make amends, this will certainly be my last Lenovo product. I will not be purchasing a Lenovo for my girlfriend or family members. I cannot in good conscience recommend that others purchase a Lenovo. My faith in the product and in the company has been corrupted. I would hate to have the new motherboard fail unexpectedly and without reason in another 6 months (which would be just after my warranty runs out), but the service provided thus far cannot justify me spending 140 dollars on a on-site service. If things don't take a turn for the better, it would seem that the best option for me may be to sell my once loved T400 when I get it back and buy a new laptop from a company that actually stands behind their product.
I NEED a laptop for school. The turnaround time I was quoted should have my laptop back to me right before school started again. I have been back to school for a week, and after all this time, they cannot even tell me when I might be able to have my laptop back. The staff flat out refused to offer any sort of temporary laptop for me to use while they held mine for an unknown period of time. I have read of people being offered loaners. They also refused to pull the system board from another T400 because "it will not work." That's just incorrect.
I want to love my Lenovo. I really do.
Edited to add more information. I figured it was better than posting multiple times in a row and cluttering things up.

T400 network cable unplugged even actually it's plugged

Hi guys,
I got a network cable unplugged issue from last week on my T400 laptop. No matter the network cable is plugged or not, it always report network is unplugged, and the two lights (green & yellow) at the side of the network cabel socket is always on even if the cable is unplugged. Plugging the same network cable to antoher laptop, no issue on network access.
Here are what I have tried:
1) upgraded the device driver (intel pro) to latest one, does not help;
2) Tried the repair function, but failed;
3) tried to restore to a point which is one week earlier than the date it stop working. did not fix the issue;
4) changed the Intel pro to 100Mb full deplex, does not work; but when change to 10MB full duplex, some web pages are accessible, but the data download is always stopped after a while. However, these two days this setting could not access web page any more. It keep acquiring IP address and always says no connection.
5) With Ubuntu 8.1, shows same issue.
I also tried the wireless to see whether can accesss the network, it even could not turn on. is the wireless and ethernet on same hardware card? now both wired and wireless out of work.
Please help to advise the possible causes, solutions or how to diagnose further, thanks very much,
Adam

Depending on the type and model of the router it is able to switch the ethernet ports to power save-mode.
Some combinations "Thinkpad vs router" do have problems with it. Disable the powersave - mode for the ethernet port(s) in the router-configuration and try again.

Creating a Booting 2.5" HDD in UltraBay for T400s

I have a T400s with a 1.8" HDD. I know eventually it will fail.
1.8" HDD are rare nowadays and not cheap compared to 2.5" drives. Same applies with 1.8" SSD. I don't want to spend a lot of money on a 250GB SSD nor install another 1.8" 250GB HDD.
What I want to be able to do is install a 2.5" HDD in the Ultrabay HDD Adapter from which the laptop can boot from. I created restore/recovery disc when I first got the T400s.
My question is how can I install windows 7 pro from the recovery disc onto the new 2.5" HDD. There are two possible ways that I can think of but not sure I would encounter some problem that would prevent me from accomplishing this.
Option a) put the 2.5" HDD into a external HD enclosure and connect it to the USB port. Insert the recovery disc in the DVD drive still in the ultrabay slot. Install Win7 onto the 2.5" external usb HDD. remove from ext hdd enclosure and using the Ultrabay HD Adapter install the 2.5" HDD into that slot.
Option b) put the 2.5" HDD into the Ultrabay HD Adapter and insert it into the ultrabay. Connect an external usb DVD drive to the T400s and place the recovery disc into this ext dvd drive. Boot off of this ext.dvd drive and then install win7 onto the 2.5" HDD inside the Ultrabay slot.
for option "b" I'm not sure if I can boot from off a usb connected dvd drive. I know on netbooks you can but not sure if I can on a T400s or if the bios somehow won't let me.
for option "a" I think I can but not sure if windows will let me install on a the blank non-formatted external usb connected hdd??
has anyone done either of the two options above?
thanks.

1.8" HDD are rare nowadays and not cheap compared to 2.5" drives. Same applies with 1.8" SSD. I don't want to spend a lot of money on a 250GB SSD nor install another 1.8" 250GB HDD.
What I want to be able to do is install a 2.5" HDD in the Ultrabay HDD Adapter from which the laptop can boot from. I created restore/recovery disc when I first got the T400s.
My question is how can I install windows 7 pro from the recovery disc onto the new 2.5" HDD. There are two possible ways that I can think of but not sure I would encounter some problem that would prevent me from accomplishing this.
Option a) put the 2.5" HDD into a external HD enclosure and connect it to the USB port. Insert the recovery disc in the DVD drive still in the ultrabay slot. Install Win7 onto the 2.5" external usb HDD. remove from ext hdd enclosure and using the Ultrabay HD Adapter install the 2.5" HDD into that slot.
Option b) put the 2.5" HDD into the Ultrabay HD Adapter and insert it into the ultrabay. Connect an external usb DVD drive to the T400s and place the recovery disc into this ext dvd drive. Boot off of this ext.dvd drive and then install win7 onto the 2.5" HDD inside the Ultrabay slot.
for option "b" I'm not sure if I can boot from off a usb connected dvd drive. I know on netbooks you can but not sure if I can on a T400s or if the bios somehow won't let me.
for option "a" I think I can but not sure if windows will let me install on a the blank non-formatted external usb connected hdd??
has anyone done either of the two options above?
thanks.

Well if you are ambishous and willing to forego the warranty you can take the lead this user did. Its not a Thinkpad but the issue is the same. The standard height SSD would not fit. You can make it fit.
Read the article further in this link. http://windowssecrets.com/newsletter/some-ugliness-installing-an-after-market-ssd/
This should help a lot of users wishing to super charge their 400's.

How do I use my lenovo T400 as a second monitor for my tower PC?

I have a docking station with DVI and I connected my tower with the laptop via the DVI cable. How do I go on?

so you have the lenovo t400 on the docking station and connecting the tower to the docking station via dvi?
i think the dvi on the docking station is only dvi out not in which means the laptop screen can not be used as a second screen.
hopefully i got it right
Thx dave

T400 with ATI Radeon HD 3400. Driver not found after running ImageX.exe /Capture

Hello,
I was able to reproduce the following problem on a T400.
- unattended installation of WXP-SP3 (slipstreamed)
- reboot
- install latest ATI driver from Lenovo/IBM site (8.503.2.2-080818a-069536C)
- reboot
At this point, the video driver is well configured.
- Reboot once or twice, video driver still good.
- Boot the T400 on WinPE 2.0
- Capture the C:\ to a network file share using ImageX.exe (from Microsoft's WAIK 1.1)
- Shutdown the T400, and reboot on C:\
- At this point, video driver is "lost". The Hardware Wizard says "new driver found", but stick with default VGA.
Then I get an ATI error telling the driver is missing or not well installed.
- When rebooting several times, suddenly the card is back in the device manager as a Radeon HD 3400.
(without re-installing the driver ...)
Anyone has an explanation ?
Please not I did not run "sysprep.exe" before capturing with ImageX.exe
stefan

Update on this problem.
After running "sysprep.exe -mini -quiet -reseal -shutdown", I ran the "ImageX.exe /capture".
After rebooting the T400, the ATI driver was fine.
Either is a coincidence (but I could repeat it 3 times...) or it is not advised to run "ImageX.exe /Capture" on a non-syspreped Windows XP.
I know that a non-syspreped Vista system has a limitation if captured with ImageX.exe. But I am not aware on any limitation with XP.

T400 not booting at all.

My T400 is not booting at all.
When I power it on, no matter it's on AC or battery, it just shows the boot screen
Black Screen with Thinkpad written (in BIG white letters).
and "To Interrupt normal setup, press the blue ThinkVantage button"
I tried pressing Thinkvantage button nothing happened.
I also tried pressing all function Keys, from F1 to F12... nothing happened
I am not too sure what went wrong, I am on travel and needed my laptop badly.
not sure what to do can anybody help me please.
System Configuration:
T400, 2 GB RAM,
Windows XP SP3,
Just one Partition on hard disk C drive.
How did this happen:
I am also not too sure but I remember few things that I did last, and mentioning them here,
not too sure if this has got something to with the problem that I am facing...
1. I compressed my C drive.
2. I had hibernation enabled ...disabled it...shutdown-ed the machine
3. Next time when i rebooted machine..i was in flight....I did work that i wanted to do ,,then enabled hibernation...
and hiberanted...
4. Before hibernation could have completed .... i closed the flap..and kept it in bag...
5. later on when i powered it on ...its not booting at all

I don't tell what caused your problem ( there are more knowledgable people here for it) but it is not wise to do these alterations you mention on a trip - better try things at home with a recent backup

Memory Problem for T400

I brought my ThinkPads T400 one year ago. In this year, I brought Window 7 and installed in my laptop. After I installed all the drivers for the laptop. I can only use 2.99 GB memory out of 4GB. What is the problem? Do everyone knows? (Everything works fine, I can use the ATI Handen 3400 Discrete Video card, and the BIOS setup for display is:
display monitor: Internal
switchable graphic: disabled
graphic: discreted graphic

Where are you seeing your numbers?
My T400 Win 7 Pro 64, Task Manager -> Performance: Total: 3990, Cached: 2374, Available" 2475, Free: 129.
That is with switchable enabled, integrated running, which IIRC would actually use more memory than your setup.

Memory Usage Issue - T400

Hello,
I got my T400 in this morning and facing a small issue with the memory usage. I ordered the laptop with Windows Vista Biz. 64bit
The memory usage at the start up is above 1.3GB. Is that normal?
I am using a desktop PC where the memory usage did not hit 900MB (I am using Windows Vista Ult. 64bit).

Hi, everyone
I got a new t440p 20ANA00UHH (8GB RAM, win8 64bits) about one week ago. It works really well, but its memory usage confused me. In Task Manager, the "Performance" option shows memory is 68% (5.4G in use), but "Users" option shows memory usage 66% (1019.5M in use). Is that normal ? I just opened some websites and word files.

Up to 8gig memory supported on T400????

Can the t400 support this much memory? I think lenovo says that it does

when the DDR3 first came out in 4 gig module, each one had costed like 900+ USD... so two of them costed same as a W500 in USA...
