Thinkpad T400 No display after BIOS update

[Biosupdate]

Hello Dears,

I have updated my BIOS via Lenovo BIOS updater and everything went successfully and it asked me to restart your computer after updating BIOS and now I do not get any display , I have waited for like 10-15 min to see if i can see anything and i saw it booted and i have updated my drivers for win 7 ultimate and upon restart again i dont have any display and i am waiting 20 more to see if i get anything .  Anyone else face the same problem here after updating BIOS?

What should I do guys next, I still have the warranty left? Does updating BIOS remove the warranty?

thanks in advance for your advise

regards

Jan

@Biosupdate,

Are you able to view the ThinkPad screen after the laptop has been booted up?

Try the solution offered by Neils, it's the last post:- http://forum.lenovo.com/t5/T400-T500-and-newer-T-series/T500-takes-15-minutes-to-boot-after-bios-upd...

If that doesn't work then perhaps downgrading the BIOS might help as suggested by wawrzyk:- http://forums.lenovo.com/t5/X-Series-ThinkPad-Laptops/X200-takes-forever-to-boot/m-p/326941#M19656

The first link worked

 Solution worked for me,

I have waited like 10 minutes for my T400 to boot up and my hands were on the F1 BUTTON and I pressed that , then i entered Config and disbaled ATM and then I went to security section which is also in Bios and i enabled i actived the security and it worked. Now I dont have to wait for my T400 for 10 min to boot and I hope the Lenovo team could find the solution because downgrading my BIOS it did not help me. 

thanks
