I have a ibm thinkpad t40. It was recently dropped and now I get a error message disk i/o error replace the disc and press any key. I Think it is a harddrive issue but before I replace the harddrive I would like to Make sure It is really the Harddrive. It dropped from the coffee table to the carpeted floor about 3 feet when I started getting this error message. I have no why to access the bios when I hit the access ibm button it tells me service is not installed are there any other whys to get into the bios on this machine? I was going to try and do a format of the drive but I cannot get the disk to boot up either. Why I would like to get into the bios to change the start up order. any help is greatly appreciated..
