Solved slow bootup with blank screen on Lenovo x200 tablet type 7449-A12 (Rev: 1.0)



When power on the Lenovo x200 tablet type 7449-A12, the screen is blank for about 15 minutes before the Lenovo x200 tablet start to boot up normally to the Windows 7 x64 Operating System (OS). The problems were due to the Trust Platform Module (TPM) was not in operational mode and the Intel Active Management Technology (AMT) Firmware needs to be updated to version 4.2.21.1037 or higher version.

Solutions:
  1. Please make sure that you have already download and installed the below for Lenovo x200 tablet type 7449-A12:

  2. In the Lenovo x200 tablet BIOS (press F1 to enter into BIOS during power on), kindly make sure that the "Intel (R) AMT Control" is enable in the BIOS "Config" -> "Intel (R) AMT" -> "Intel (R) AMT Control". Below are the default setting for "Intel (R) AMT Control" in the Lenovo x200 tablet BIOS:
    • AMT CIRA timeout = 0 (default to timeout at 60 seconds)
    • Console type = PC ANSI
    • IDE-R for normal boot = Hidden

  3. Please download Intel AMT 4.2 Management Engine (ME) Firmware version 4.2.21.1037 (7ur6c4ww.exe) or higher version. After extracting the 7ur6c4ww.exe to a directory, and after reading the installation instructions, I opened a Command Prompt with "Run as administrator" right, and run the "meupdate.cmd" file. It will takes about 3 minutes to update the Intel AMT 4.2 Management Engine (ME) Firmware in Windows 7 x64 OS. After that, kindly reboot the Lenovo x200 tablet. You will immediately see a normally boot up screen (no more blank screen for about 15 minutes) on the Lenovo x200 tablet.

    In the Windows 7 x64 OS, the Intel TPM will be in "Operational" stage with "inactive: Unowned: Enable" settings. The "TCG Spec Version" is 1.2 and the "Firmware version" is 4.2.21.1037.

An x200 in my organisation suddenly began displaying this behaviour. Type 7458-54M Vista 32bit worked a treat. Cheers

Awesome tip and thank you a million times. This saved my rear end. I can't believe Lenovo couldn't make this simpler.

This did the trick on a regular x200 (not a tablet - 7458). Thank you very much for sharing this.

Your solution worked - thank you!

I searched all over the internet and received all sorts of incorrect advice (e.g., upgrading Lenovo's Client Security Software, etc.). This was the only place I found with the correct solution that worked. I was getting close to pulling out my hair with the 10 minute delay on reboot and this fixed it!

FWIW, I have a X200 7459 with Win 7 Ultimate and started having this problem after upgrading to bios to the latest version.

Hip, hip, hooray, this worked on my regular X200 as well.
All of a sudden, the boot time was really slow and long.
Where I thought the computer was hung, and I just happened to leave it running to see if it would do anything after a while.

Two thumbs up Jack, thank you for sharing this, you saved my butt. I was kicking myself in the butt for upgrading the bios. I'm glad I stumbled onto this post and your helpful fix!!

My lappy is a X200s, 7470-5HU, I was going from bios 2.04 to 3.21, upgrade was done via Win7 32bit.

Thanks again...

Dear Bolo,

Please make sure that your Windows Operating System language is English language. Kindly download the English version drivers and try the update again.

My Windows is 100% English and laptop is from USA but drivers.. I don't know... I downloaded it from your links but maybe it was forwarded. Could you upload your drivers?

Jack Ng said...

Dear Bolo,

I clicked on both the links & was automatically forward to the below 2 links in English (en_US):

Intel AMT 4.2 Local Manageability Service (LMS) and Serial Over LAN (SOL) Driver

Intel AMT 4.2 Management Engine Interface

It is advisable to download the drivers from Lenovo website in order to get the latest drivers.

Please try again. Thanks.
