Now I cant load anything on it??? It boots up and says "invalid system disc" I have an external Floppy drive and an external cd drive. even when they are not conncted it says the same??? HELP PLEASE....
I have another computer (desk top) so getting os and boot disc from net is easy also am not scared to take 240 to bits with correct tools or hammer if needed and will fit new parts but other than that , I am an idiot so if you know how i can fix this please please put it simple for me.....?
P.S also what is the slot on the left hand side of the thinkpad for?
