Can't be done I'm afraid and as you don't have a CD, you can't revert to factory settings unless IBM ofer you that at the first black sceen you see at startup. If a Function key isn't offered at that stage, there is no factory recovery.
Don't buy a CD on e-Bay - most are fakes and won't pass activation or genuine advantage tests. The laptop has a future though - a Linux operating system is just as good if not better and costs nothing. Download and burn your own bootable CD and you can test that as a LiveCD without installing to test if you like it or not.
A good one for starters is PCLinuxOS and that comes from http://www.pclinuxos.com. A good utility to burn bootable disks is ImgBurn and that's free as well.
The obvious fix here is to ask whoever you bought it from what the password is.
