• ThinkPad T400 does not start, is turn on below the screen & turning HDD switch off in a loop

  I put my Thinkpad T400 hibernation, but the next morning I couldn't start. When I press the power button, the lights under the screen turn on and I hear the sound of the hard drive and get it out. I don't even see anything on the screen. It is only black. The process continues to repeat in a loop, except if I press the power button to turn off.

  I tried the static load, remove the thing.

  I also removed the hard drive, put it back again, but not working anymore.

  Help, please.

  Solved the problem myself.

  Removed the internal battery and reinstalled after 30 s.

  It worked perfectly. Typing of him now.

• ThinkPad t400 not turn on!

  Help!

  I just poured the water on my thinkpad a little water just for fun, but when I turned it on, it does not fuel upward!
  I'm sobbing on this loss.
  I thought that my thinkpad had also the drainage holes.

  Please help, please help!

  Hi all
  IT'S MY EXPERIENCE THAT IS POURING WATER ON MY T400.
  I got to pour the water on purpose on my Thinkpad T400.
  I'm very young but I just removed the four screws of ram and also removed a screw of keyboard as well.
  I opened the lid, and then I removed the touchpad. Then, I also removed the keyboard. I noticed the water entered the cooling fan and I also found water near the Intel Core 2 Duo processor. I also found water near the hard drive and in the custody of the enclosure, so I removed the Panel silver inside the laptop. I also removed the CD player. I let it dry under a FAN (I did not use a hair dryer, as this may damage the components. Then I put everything back up 3 minutes.i lit .he not even turning on, instead, I hear 1 beep, 3 beeps, 3 beeps 1 beep. I surfed on the internet and found that the error means that RAM is not correct or there is a problem. I still once reassembled RAM as it was before (I changed the arrangement before that caused this error).
  Then, to my surprise I saw Thinkpad on screen and the Windows XP operating system started to load!

  I checked if I had connected the keyboard and the mouse properly. Everything was fine.
  I LOVE MY THINKPAD.

  You can use this method, BUT be extremely careful you don't have static electricity.

  Kind regards

• How to upgrade to windows 7 on Thinkpad T400?

  I brought the Thinkpad T400 in 2008, I want to run windows 7. I know that I need to update my BIOS to activate windows 7. I'm going to buy a windows 7 at BestBuy, is it OK?

  can someone tell me the steps? Thank you very much.

  My Thinkpad T400 is CTO of 2764

  Intel Core 2 Duo P8400, 2261 MHz

  ATI Radeon HD3400

  BIOS:

  Version: 7UET43WW (1.13)

  Date: 08/19/2008

  SLIC:

  Version: 2.0

  PubKey: LENOVOTP-7U

  Marker: LENOVOTP-7U

  The SLIC table is only important for Windows pre-installed.

  Buy Win7 and install it on your computer. Activate it on the internet after all the drivers are installed and working properly. After that drag an image of your HARD drive as a backup to an external drive.

• New Thinkpad T400 is not start the system

  Hello world

  I received my new Thinkpad T400 a month ago, product ID 2764CT 0. I told my computer to the hibernate after that the battery power is 5% of its capacity. I forgot to put the computer off last night and this morning, when I plugged the power cable has tried to turn on the computer, it wouldn't boot. The screen is completely turned off and would not turn on no, I know that the computer is turned on, because I can feel hot air coming out of the vent in the heat. 'Z' light was turned on, but the computer does not respond. Except for the CD player, no contribution has no effect on the computer.

  Can I call customer service for this problem, or is there a way to fix it myself?

  Thank you.

  Unfortunately, my thinkpad would not even start up. There is no video, and he wouldn't respond to all entries. It has a Z (the Z letter in a circle) light on, but other than that, it doesn't work.

  Seems it's time to get it in service from lenovo, give them a call.

• L.H.S heat exhaust vent Thinkpad T400 is broken

  Hello world

  I happened to be in a hurry to do something really important, and I wore my laptop too.

  When I was almost a corner of a table, I accidentally hit the Thinkpad on its cutting edge. (oops).

  Then the result was that on the left side,

  vertical bars (for cooling) has been broken.

  Really, I cherish my Thinkpad I really wish she was fixed.

  This can be corrected? or do I have to replace the whole Panel?

  Thank you

  Chris

  I wouldn't worry much; I broke things on my T400 a long time earlier.

• ThinkPad T400 not display after BIOS update

  Hello dear,

  I updated my BIOS via Lenovo BIOS update and everything went successfully and it asked me to restart your computer after the BIOS update and now I don't get any screen, I waited like 10-15 min to see if I can see something and saw it started and I've updated my drivers for win 7 ultimate and when restarting again I don't have no matter what screen and I wait 20 more to see if I get something.  Anyone else facing the same problem here after the BIOS update?

  What should I do guys then, I always let the warranty? Update BIOS removes the guarantee?

  Thanks in advance for your advice

• My ThinkPad T400 does not start!

  Honestly, I have no idea what could have caused this!

  I turned it on this morning & it was stuck on the startup screen. It read "ThinkPad" in big letters followed "To interrupt normal startup upward, press the blue ThinkVantage button." Waited about half an hour for him to start & it never did. Of course I pressed the ThinkVantage button & to my dismay... nothing happened. Subsequently, I have unplugged it & removed the battery. I then plugged it back in & tried to start again. Once again, nothing. I unplugged it new & attached to the battery. At this point, I tried to go back to the top and N O T H I N G!

  What should I do?

  Take a look at your usb ports, there could be some sort of pins to touch, as a result of the damaged usb pins.

• ThinkPad T400 screen broken

  
  

  It is a CCFL Backlight, which is easier to find than a LED backlight. A panel of a T400, R400 14.1 "or 14.1" widescreen T61/R61 will fit. With T400/R400, you must be sure to get one with a CCFL Backlight. You can use a (1280 X 800) WXGA or WXGA + (1440 X 900) display.

• Crucial 128 GB M4 + BSOD Thinkpad T400

  Just traded my old Samsung SSD with no TRIM for a Crucial M4 128 GB.

  It was very good, so I left it overnight installing drivers.

  The next day, I started to install all my apps and I was getting BSOD all the time.

  Anyone have any ideas? its alignment, sound in AHCI and TRIM is activated and on the last Firmware 0009

  I have disabled LPM now and I'll see if that helps, its amazing how much faster the SSD is, he almost ignores the Welcome screen

  It's just a shame he tops out at 280 MB/s because of the SATA2

• T400 connection to TV

  Hello. I have a ThinkPad T400.that has 3 USB ports, 1 firewire, VGA and audio 3.5.

  I also have a TV that has the following text

  2 HDMI, 1 port (shared with component) USB, RF, Composite, component of the Digital Audio Out (Coaxial s/PDIF)

  I'm new TV connection and laptop, so I have no idea what these things mean. I want to be able to connect the laptop to the TV sometimes display presentations powerpoint or screenshare other presentations and maybe see the netflix and hulu.

  I searched the internet for instructions on how to connect these two but I find a lot of contradictory information. What types of cables or converters do I need to share the audio AND video? I think that maybe the answer is a combination of 2 cables. A VGA to component and composite out headphones. Is there a reason that HDMI must be involved in the process?

  Antone who succeeded in this regard, please teach me how. Thank you for your time.

  Well, I finished just buy another TV. I made sure to read the box to see she had a VGA input and a PC to TV, audio port. It was easier that trying to understand on the connectors, I would need and if the sound will work correctly.

  Thanks for the ideas so. At least I'll know what things to try if I decide to use the laptop with another TV.

• T400: randomly turns off

  Hey everybody!

  First time poster here!

  I've recently updated my Lenovo ThinkPad T400 with a Crucial M500 (240GB SATA SSD 7 mm) and 8 GB of RAM Kit (PC3-8500 DDR3 NON - ECC).

  After a few days of trail and error, I finally installed (successfully, I might add) Windows 7 via USB. I leave my laptop on when I SLEEP, but in the morning she is cut off. When I power it on I get the windows is not stopped correctly and I always choose the option "Start Windows normally" and, in addition, Google Chrome informs me that it was not closed correctly and restores my tabs.

  I have no idea why it randomly closed OFF... ideas?

  Also, when I try to run my noting system after one or two flashes of the screen than my laptop turns off, so I'm unable to do this as well.

  

  
  

• The T400 2768 L 35 WWAN is ready?

  Hi, I bought a T400 2768 L 35 (impossible to find this serial number in the standard list, but that's what it says on the bottom plate of my laptop) my university IT shop a couple of years. I have a 3G compatible SIM card and I would use it on my laptop to surf the net. I found SIM card but did not see any WWAN card in Device Manager. Is there a way I can go online via WWAN? Or am I doomed to rely on wifi

  Welcome to the community.

  as long as it has not changed, this is the hardware configuration for your machine:

  ThinkPad T400 (2768-L35): T9600(2.8GHz), 4 GB of RAM, HD 500 GB at 5400 RPM, LCD 14.1 in 1280 x 800, 256 MB ATI Radeon HD3470, CD-RW/DVD-RW, Intel 802.11agn, option WWAN, Bluetooth, Modem, 1 Gb Ethernet, UltraNav, Secure Chip, reader of fingerprints, camera, 4 c Li-ion, Win7 Pro 32

  the key word above is option. because you do not see a device WWAN in DM, you have probably no card installed. you mention you location SIM, then you probably also have the WWAN antenna, but for sure, you can check if you are comfortable pulling the palmrest and keyboard. Please see the hardware maintenance manual here:

  http://download.Lenovo.com/pccbbs/mobiles_pdf/43y6629_04.PDF / pg100-101.

  If you find the sons of antennas not connected, all you need is a proper map and drivers. the important thing to consider is that the card must be on the BIOS 'white list' trusted network devices. If you scroll down to pg150 of the HMM, you will see the map in the exploded views as ex. No. 25. scroll further down to pgs273-275 who see there are 3 cards listed with their #s FRU. While you are looking to buy, be sure to get a genuine FRU role, rather than a generic/universal model.

  Finally, you can get the driver of the pilot matrix, here:

  HTH a little.
