BIOS Post codes?

[bfgun]

Can someone tell me what this bios post code means? I have a T43 thinkpad, opened it to blow some dust out then put the keyboard back in.

Now i get 4 fast beeps, then 3 slow beeps. Nothing displays on the screen.

Thanks,
B

The beep information is in the Hardware Maintenance Manual.
