Hello
1 long, 2 short is an error with the video adapter. This isn't specific to IBM systems either, that code is the same for pretty much every BIOS out there.
It seems your video card may be at fault. has anything changed? do you have any picture on the display at all? If you have zero picture it will be hard to get into safe mode and try to roll back drivers etc. It may be that the video adapter is just defective. You can contact IBM/Lenova and see about getting a replacment or you can take it into an authorized repair place. You can also attempt to obtain a replacement video adapter for the T61 and install it yoursel fif you have the knowhow
Hope this helps Good luck!
