Preferred Solution: Thinkpad t400 notbooting

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Hi Punittiwari3353,

Welcome to Lenovo Community!


Have you checked it individually with battery and without battery?
Did you check with different power adapter or with different power socket?
Is the CPU fan running with regular speed?
Boot the system into ?Safe mode? and check if the issue persists there also?

Hope this helps. Do post back if the issue persists!

Best regards,
Hemanth Kumar

Hi, I've searched the forums and elsewhere online, and I can't find any real help for this issue. I'm running Win 7, and I have the most up-to-date drivers from the Lenovo site. I have turned on loudness equalization, but it has not helped the problem. This is an across-the-board problem. What I mean by that is, this problem persists regardless of the application, which I happen to be using. For instance, I use Media Player Classic: Home Cinema to watch movies. If the volume is at 0%, as I begin adjusting it upward, the volume level rises. However, as I reach about 70%, the volume stops increasing. There are audio adjustments w/in the application to boost the volume, but they serve to provide minimal effects. Overall, the volume is incredibly low. If you're sitting more than a few feet away from the laptop, it is inaudible. I don't know what else to do, and I was hoping that someone might offer some assistance. Thank you.  Jeff

A:Thinkpad T400 Volume Too Low

Welcome to Lenovo Community! jmg999
 
How about uninstall your current Conexant driver and install custom Dolby driver from my signature link? It should help to boost a lot. In fact, T400 speakers are louder than other new T-series speaker.

I honestly have no clue what could have caused this!  I turned it on this morning & it was stuck on the booting screen. It read "ThinkPad" in large letters followed by "To interrupt normal start up, press the blue ThinkVantage button." I waited for about a half hour for it to boot & it never did. I of course pressed the ThinkVantage button & to my dismay...nothing happened. Afterwards, I unplugged it & removed the battery pack. I then plugged it back in & attempted to start it up again. Once again, nothing. I unplugged it again & attached the battery pack. At that point I tried starting it up again and N O T H I N G!  What do I do?!

A:thinkpad T400 Ram Upgrade

RAM: You need a minimum of PC3-8500 1066MHz DDR3. However faster chips like PC3-10600 1333MHz DDR3 or PC3-12800 1600MHz DDR3 will work fine as well.
 
If there's little or no difference in price I'd buy the faster memory. The reason is that if I upgrade to a new(er) notebook it's more likely the RAM will work at full speed on that system.
 
Note also that while you can upgrade to a maximum of 8GB (2x 4GB) with a 32-bit OS like WinXP-32 you won't be able to utilize more than 3GB.
 
SSD: Any of the drives you've listed will work well.

Now, I suspect that the inverters are fine and I'm wondering about the LCD switch or LCD cable. I suppose I could just buy a cable, but before that, I wanted to take a step back and try to figure out if I'm overlooking anything. I've not been able to find a picture or location of the t400 lcd switch in either the lenovo hardware manual for the t400 or elsewhere online.Hi,I've got a thinkpad t400 with CCFL backlight. I recently replaced a bad LCD (the backlight was working at the time) with a new one. However, while the new screen works, it's backlight did not. I ordered a new inverter and plugged that in - still didn't work. I grabbed the old screen's backlight and tried it with both inverters - did not come on. I then grabbed another laptop I have and plugged in the old screen's backlight - it came on. Plugged in the new screen's backlight (while lcd was still plugged into the thinkpad), it's backlight came on.So, I know both backlights are fine, and suspected I just had a crappy inverter. I got a replacement new inverter and it still doesn't work. Tried new lcd and old backlight with all three again, no dice. Backlights still turn on when connected to spare laptop. So I now suspect the inverters are fine. I noticed that the laptop no longer goes to sleep or hibernation when the lid is closed.

I have a thinkpad T400. Couple of months ago the problem started. I could not shut it down it just keep re-booting. I had to press and hold the start button to shut it. Now it won't boot at all. It beeps 1-3-3-1 and just sits there. When I press start button all lights come ON for a while and after only battery , AC and Ready lights stay ON. Here are few things I did so far without any luck: 1. Removed battery and AC adaptor waited few minutes put it back - same problem2. Removed CMOS battery. DIMM cards waited for ten minutes replaced - same problem tried with swapping  DIMM cards - when I put only one card on top slot it says put the card on zero "bottom" position. After placing the Mem card on the bottom slot no thing happens. It beeps again and sit. When I checked in the manual it says either DIMM or System board. I do not know which one is giving me the problem. I just do not want to replace all parts without knowing. Can any body help please or had similar issue and solutions if you managed to solve it. Thank you. Roshni

So I uninstalled the antimalware. So I can't really run to see if I have a virus.  To make a long story short right now NONE of the function keys work nor the THINKVANTAGE.  When I reboot and attempt to go to safe mode, bios utility I get nothing except opening up windows where sometimes the cursor will open a program or not and the trying to open programs from the start menu or the task bar is hit or miss same happens in the start menu and trying to open a browser.  I am running on Windows 7 Pro 64-bit and would like to go back to factory settings, but ag...

Hi,

Lenovo Support & downloads - ThinkPad Switchable Graphics Driver for Windows Vista 32bit and 64bit - ThinkPad T400, R400, T500, W500

and when I rebooted, it went through some diagnostic tests in a cmd window to finish installation. But when I checked the device manager again, the ATI adapter still says it cannot start.

I also tried this:

ATI Catalyst? Mobility Display Driver

which I got to by selecting W7 32-bit > Mobility Radeon > Mobility Radeon HD 3000 series.

It seemed to install OK, but I got a message which I've gotten with previous attempts, which says:

We have verified the image and the issue is related to LCD panel, but I suggest you to check with reseating the LCD cable on both the side which is connected to the LCD panel and also to the system board.

First, my t400 would only boot with power cord unplugged. Then it stopped booting altogether. I read to press the power button 10 times and hold it on the tenth time and to unscrew the palm rest to unplug the little battery for 30 seconds. That is the only way I can get it to boot now. I picked up a new regular battery today thinking it might be related but that hasn't solved it. Any ideas?
 

A:thinkpad t400 wont boot w/o reseting little battery behind palm rest

I looked at it closer and to get it to start i don't press the power button at all. I unplug the power cord and after unplugging the CMOS battery for awhile i just plug the power cord back in and it starts up. The first thing i see as it starts up is an error message about a bad CMOS checksum and then i have to change the date/time in the BIOS or it yells at me to do it. After all that it boots into windows 7. Once it is in windows no matter what i do to change the settings of what the power button does it still doesn't do anything. I can restart it fine but once i shut it down it the CMOS battery needs to be reset to get it going again.

Mick.

A:t400 questions

What operating system is your T400 running on? Seeing that it is a considerably old laptop, one can expect it to run quite slow. If you want decent performance you'll want something at least an i5 processor, an SSD drive, and 4GB of Ram. If the writing is not clear to you it is probably because it has a low resolution display. Not a whole lot you can do to change this. If the cursor is choppy. Your best bet is to get the latest drivers. Try downloading them here https://pcsupport.lenovo.com/us/en/downloads/migr-66898 To get photos from an SD card onto it, you could get a SD card reader to USB adapter. In reality though, you might be better off just buying a different machine altogether.

Hi all --  Longish post, need help, please read! Recently my T400 has been creating significant heat under load. After combing through a number of T400 heat issue posts I decided it was likely some combination of too much dust and insufficient thermal grease. So, I poured over the hardware maintenance manual (HMM)... I disassembled the system, extracted and cleaned the fan, removed existing thermal grease off the CPU, GPU and Southbridge, reapplied Arctic Silver 5, reinserted the fan and reassembled the system. Everything seemingly worked well. System booted without issue and the temperature difference was noticeable (TPFancontrol said so, anyway). To test the machine I decided to put the system under some significant load -- a few crazy calculations in Excel. It chugged away for about 10 minutes and then... BEEP BEEPrebootFAN ERROR My resposne: FML. But I can deal with a little adversity; so back to the forums and the HMM. All signs pointed to replace fan. And so I did -- ordered a new fan yesterday knowing full well there was no way to restock it because they don't take returns... and the $100 this part cost isn't exactly chump change. (Note, I find it highly unlikely the FAN is worth 1/15 of what my original machine cost me). I digress... A new fan arrived an hour ago (at least the parts counter is efficient) and I replaced the old fan. I'll be frank, I didn't replace the thermal grease -- the new fan assembly had plenty... I re... Read more

A:T400 FAN ERROR

The grease that comes with the fan is fine. It is at least as good as what you buy and it is applied better than you can. My guess is that there is a blown fuse (F4) on the motherboard, but it is hard to diagnose from 3000 miles away. Lenovo does not replace fuses. It requires a good soldering station - not a simple soldering iron. They just swap motherboards. Make sure that the fan spins freely and is plugged in correctly. Antenna wires can get in the way if they are not run properly. If you don't want to fix, I would discuss an exchange, but that should be done through private messages.

Every once in a while it will just shut down, I've taken a infrared thermometer to the bottom of the unit and measured ~163 F surface temps!!I've had TPFanControl installed since the vista days (my warranty had just expired by then), as I had experienced some overheating issues.  I installed Windows 7 and it seemed to run much cooler...but recently I am having issues again.TPFanControl shows 62C and dropping at the moment (now it's 59C), but it was reading 73C+ before I switched fan control to manual. The fan speed is now at 3422RPM instead of the ~2000RPM it was reading before (at 73C). It seems to run sluggish....I'm sure 70C+ temps aren't normal, right? Compared to my home built six core AMD system, which idles around 35C...About a year ago I took the keyboard off and blew out the dust....seemed to help a little. Also made sure the heat sink screws were tight. My next option seems to be taking the heatsink off and apply some arctic silver paste. Curious to see what others have experienced...This is my first Thinkpad...I was always told they were rock solid. This one has been quite flaky.

Need guidance on finding drivers for T400 running WinXP.  I know XP is "obsolete" (by virtue of vendors saying so) but the laptop is in fantastic shape and very, very stable.  Just need to undo tweaks that didn't produce the intended effect, so now I'm looking for drivers to get the powermanager, fingerprint reader and PCI simple communications back working.  Lenovo seems to have pulled those from the website.  Following their links leads to a sever error.  Any help would be greatly appreciated.

I have a problem with the right side USB on my T400, obviously a pain the butt so in the service manual section 1180 covers the disection to get at the USB sub assembly, almost literally have to take the machine completly apart I have the PCMCIA/Express Card version which is adequate for my needs. I have a USB 3.0 card installed in the top slot. no pain, no gain, so is the USB sub assembly fixable, USB shows a device error suggesting a signal problem and I wonder if there is a problem with the logic board as opposed to a damaged port

I went to sleep last night after setting my T400 thinkpad into sleep mode, and I woke up in the morning to 'un-sleep' it and it flashed all the little icons on the little status tray below the screen before they all turned off and nothing happened. I tried to unplug the laptop (Having plugged it in when I woke up) and got the same results minus the 'plugged-in' status light blinking. I tried it without the battery in (but plugged in) and it happened again. I'm not sure what else I can do, because I can't even get the computer to even start up. I would love to have the problem resolved. Thanks in advance for the help.

A:T400 not powering on

Try removing both the power and the battery and holding the power switch down for 10-30 seconds. (more is better since I don't remember the exact number).  Put the battery and power back on and try powering it up.  If this doesn't work you can try removing the palmrest and pulling the cmos battery as well.. here's to hoping the first idea works..  Best of luck!

Hello, I have recently picked up a used T400, it had no OS installed and I happen to have a copy of windows 7 pro with a key. Will I need to install any drivers or extra software with windows 7 or will everything work fine without drivers? Thanks

A:T400 Drivers...

Hi T400man and welcome to the community,
 
Once you get the OS installed, run Windows Update and try to not install updates pertaining to hardware drivers.  You'll need Net.Framework 4.0 installed and then you can install TVSU and it will find and install hardware drivers for you.  It's not a good idea to install every driver that it finds all at once, especially if your machine needs a bios update.
 
If TVSU determines that you need a bios update and you want to install it, install that one by itself.
 
Regards,
Dave

So, I am working on building my sister a new laptop, for the task I have picked a Thinkpad T400, I bought this laptop for Ģ40 off ebay and am very happy with the conditions of it, it came with an Intel P8400, 1GB of RAM and no HDD, this is fine as i have ordered a T9900, which it yet to arrive, a 250GB 850 EVO, and i planned to use the 8GB 1333 DDR3 kit out of her old laptop, this consists of two 4GB modules and are 1.35V, now the problem is that the thinkpad will refuse to boot with any of these modules, not even if one is installed, it simply throws the RAM issue post code and does not start up, i am curently running the latest bios available however it is simply not working, sadly it looks like i am going to have to purchase new RAM but I am not sure what to purchase as corsair apparentsly have issues with the T400 and Crucial recommend 1600mhz DDR3L (1.35V) so i am not sure if this will work, could you let me known of known working memory, why is the current memory not working and will the crucial reccomended stuff work?

I think I blew a fuse on the motherboard of my T400. The on board camera stopped working when the ribbon cable disconnected from the screen and camera while I was replacing the screen hinges. That's what I get for not cutting the power prior to the repair. My problem is I can not find anything that will tell me where the fuse is that powers the camera and the specs of the fuse. Everythig else is working fine. I even replaced the on board camera first thinking that was the prob.

A:T400 Motherboard Fuses

 First, questions:  Do the status LEDs on the LCD bezel work?  Do all the USB ports work?  If the status LEDs are out, there is a 0.5-amp fuse near the LCD cable connection.  However, my guess is that the LEDs will still work.  I haven't worked on a T400 for a while, so this is from memory.  The camera, I believe, is actually a USB device, which is why I am asking about the ports.  Do you have Bluetooth?  Does that still work?

Hello, this is my first post. I've bought a used T400 recently, and it had a working bios when I bought it. Now that I have an SSD for it, I tried to install Fedora 26 on it. I put in the CD (that I verified on a different computer), selected it in the Boot menu (F12 on start up), then it goes to a black screen with with a blinking white purple, then it restarts after a about a minute and goes to the same black screen. I made a live USB, but that gave me the same result. I have read somewhere that such issue can be fixed if I disable secure boot, I don't see the option to disable secure boot. my BIOS version is 3.21, would updating it fix it? Also if I turn it on without charging cable, it says "0190: critical low-battery error", charging it for a while doesn't seem to fix it. (Battery indicator is orange and is flashing about 2 times a second). I was thinking that it might be the issue with the operating system that I'm installing, so I'm planning to try Debian tomorrow. Thanks,Alex

Oh where do I begin...  I'm having issues with the two buttons right below the touchpad.  The left button spontaneously stopped working.  I can't drag and drop anything.  I can't select anything but I can close a window.  I can single click on a link, but I cannot double click.  If I click on a button on the start menu then a window where I clicked will pop up asking if I want to open the application or show on the desktop.  When I click on the bar on the scroll bar it stays pressed until I click it once more.  If I try to drag and drop a mp3 in iTunes the file stays attached to the arrow, when I depress the left button the mp3 is still attached and the only way I can separate the mp3 file from the mouse is to press the escape key.  I can't click on the right button to bring up the mini menu to copy, paste, select all, etc... things either. I've attached some screenshots as to what my settings are and the issues that I've been experiencing. I've updated the driver.  Then uninstalled and then reinstalled the driver and the ultranav software. http://i51.tinypic.com/20r1yy8.jpghttp://i51.tinypic.com/2uh64nl.jpghttp://i54.tinypic.com/2aik3fp.jpghttp://i56.tinypic.com/2v940ub.jpghttp://i53.tinypic.com/2hxumwj.jpghttp://i54.tinypic.com/1603osl.jpghttp://i53.tinypic.com/10wp20z.jpghttp://i53.tinypic.com/11tt05c.jpg  (This happens whenever I click on the desktop with the left button)http://i55.tinypic.com/2e4du3a.jpg
