I have a Lenovo thinkpad E40 laptop, the mode number is 0578-CTO. About a week ago I tried to installed some driver from lenovo official website, afterward it started to have a boot-up issue--for ~90% chance, the laptop froze at the first screen which displays the big logo "Thinkpad" . It never get beyond this point to the operation system. I installed several drivers but I think it must due to the "ThinkVantage System Update 4.03" since it's the only one has something to do with BIOS, and I never had this problem before.
For about 10% chance the laptop was able to get beyond the frozen screen, boot Windows and everything works just fine, all programs, all my files are all functioning appropriately like the laptop has no problem at all.
The situation becomes worse and worse with time, and it finally doesn't boot at all today. (After more than 10 hours of trying, finally I got it turned on and I'm not turning it off again) I called Lenovo custome service and they said I need to replace my whole motherboard and it cost at least $575 which is almost the price of this laptop. I think it must be a software issue--the update screwed BIOS somehow. I don't know why thinkcentre post such a software making people incautiously update their BIOS and screw it up. I even want to buy a BIOS chip and replace it myself.
So, is their any solution to it? The simplest one I can think of it to install a old-version system update to change my BIOS setting back, but I cannot find any.
Any suggestion will be appreciated.

Have you tried reverting back to an earlier restore point? Here are the steps to do that if you need them:
Let me know if this helps.

There's no restore point eariler than the problem. The earlist one is last Sunday. I don't want to try that point since it will restart my computer and I really don't want to do that unless I'm convinced this problem is fixed.
This is also the reason I cannot re-install the operation system. The installation process requires several restarts, but the freezing problem happens BEFORE it tried to boot from somewhere (DVD drive, usb, harddrive, or anywhere else), so the frozen problem will happen regardless I have my system disk inserted. Plus I don't think operation system will change BIOS setting. Moreover, any key (including Enter key and all F keys) doesn't work at that frozen screen.

I would first try to reset BIOS if you can get into it. I just noticed in your first post that you say laptop, but you posted in the ThinkCentre forum. Which is correct? What model and OS are you using?
Could you try to clear the CMOS if you can't get into BIOS (only do this if your ThinkPad is out of warranty)?
The process is on page 54 here: http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles_pdf/75y4302.pdf

It is a thinkpad laptop. I posted it worng...
BTW, page 54 in that PDF only tells me how to check battery pack, it didn't say anything about how to clear it.

I'm sorry. It's page 98. The preceding pages will tell you how to remove the keyboard, etc to get to it. Leave the CMOS battery unattached for 15 minutes or so to fully discharge.

OK. i think now I'll just keep it turned on. I'll try this method someday in the future when I have to restart it.
Thank you Ron for being so patient answering my questions!

Sure. Let us know if you have any other issues. (Clearing the CMOS will reset your BIOS setting to default.)
