T400 BIOS upgrade failure - what next?

2010-11-24, 7:29 AM

Hi there - I am looking for some help with my new T400 6475-UC4.  I was upgrading various drivers and software using the Lenovo toolbox.  One of the upgrades was the BIOS.  All was going well until the system froze rewritting a block.  I didn't capture the exact screen message.  I left the upgrade running in the vain hope something would happen.  It didn't.  Searching the forums I have read some people have tried the follow bootable CD BIOS flash.




So I have tried that.  When I switch on the T400 the disk spins but before it gets a chance to do anything there is a long beep followed by 2 short ones.  I have 800+ warranty days left, is the only option to send this in for a repair?  

Thanks for any anticipated support and advice

you have no other options other than send it in. Luckily you have warranty remaining, otherwise you would need to pay for a new motherboard.

There might just not yet be the need to launch a whole warranty case  in my opinion. The link you refer to is only usable if you have a fully functioning bios. Your case is special. You're facing a corrupt bios.


May I ask you if you get to see the initial boot screen (typical white Thinkpad & intel logo on a black background)?
