Hi, I have a 1920x1200 external moniter connected to my t400 via VGA. I'm on 32bit vista and was using the dedicated ati mode "performance mode" to output my external moniter. Everything was working fine until I hit "lenovo update" and installed everything that was "recommended" and "optional". Now whenever I hibernate my computer and try to resume it...it completely freezes up. I have no choice but to proceed to hold the power button down for 5 seconds and shut it down manually. When I restart it it tells me to choose to resume hibernate and I click on it and then it gives me a BSOD. After that I once again hold the power button for 5 seconds and watch as lenovo takes 5 mins to scan my hard drive completely.
Basically, the new updates have screwed up my t400 horribly. I unfortunately disabled system restore and i vague remember seeing a bios update and new integrated graphic settings. Anyone know how I can fix this? thanks

you could try to reverse the bios update by downloading the old bios image and reinstall them, to see wether that works.

thanks that sounds like a really good idea except after about manually restarting my comptuer 5 times in a row it's lagging massively now and i cant even control alt delete without it giving me an error. i cant delete any files without the whole explorer freezing on me now.

Hi, my t400 is still not working properly after i set it to "factory defaults" I think it's becuase I downloaded the BIOS without looking at the notes.
"f you use Windows Vista, before applying this BIOS into the system, you should install Windows Vista KB 937500. The information of KB937500 is located in the following Microsoft's site.
To verify if KB937500 is installed properly,
so basically i think im missing that file. or do you think i should try to download the old BIOS again and try that?
also how would i go about installing the older bios again?

what bios version are you on now? You should just back date the bios, i have found that some bios updates cause funny problems.

i dont have the same problem but i downgraded the bios back to 3.01, because after installing the newest 3.09, the fan was on all the times.

yes you backdate the bios by installing the old bios image over it, but since your laptop is unstable in the OS, it is advisable that you do it as CD rom image, rather than through the windows, since if the process stops in the middle of the update, most likely your laptop would end up as a brick.

go to bottom of the page and download the bios you want
