Lenovo T400s just freeze

2010-07-13, 6:48 AM

We installed on three T400s Laptops Windows 7 Prof 32 Bit and all of them freeze sometimes after a couple of hour work. After that you need to hold the power button and restart the notebook. I already installed all the newest drivers on them. I switched off all the power options in BIOS but we still get this problem. Where could it be? What else could I try?


I'm happy for any advice.

I have the same anoying problem but with a Lonovo T400 and with win7 x64. The shutdowns also happen really randomly and I did not managed yet to determine the problem.

Sometimes my screen just freezes and the computer does not respond to anything and sometimes it shows a BSOD before it wents black but most time it just shuts down/ goes blck. Every time this happens, the LED on the left side next to the battery LED is illuminated as if the notebook still runs! To restart it I first have to hold the power-on button until the notebook is completely off and then restart it. The system protocol says the following (german windows):


  Problemereignisname:    BlueScreen
  Betriebsystemversion:    6.1.7600.
  Gebietsschema-ID:    1031

Zusatzinformationen zum Problem:
  BCCode:    7f
  BCP1:    0000000000000008
  BCP2:    0000000080050031
  BCP3:    00000000000006F8
  BCP4:    FFFFF80002E9BE58
  OS Version:    6_1_7600
  Service Pack:    0_0
  Product:    256_1


Sometimes it is also just the Error 41 (Kernel-Power).



What might be interesting is that the complete issue never happened if I booted in safe mode. Maybe you can check if that is true for you too? I also own an advanced mini dock and when the notebook was docked I also never experienced this error.


I hope somebody is able to help, since working normally with this notebook is almost impossible!
