A friend of mine has a IBM thinkpad 770 and on start-up he receives an error 8611. IBM website says that it is either the motherboard; on-board mouse; external mouse; etc (long list...lol). He had it on-line and had IBM did ran a diagnostic test and they told him it was a broken wire on the external mouse. Being an electronic tech I didn't hesitate to open and inspect. Upon Visual inspection I could find nothing that looked cracked, bent or broken. Is there a way to bypass the boot-up diagnostic test so windows will load? I am able to boot to dos with a floppy and can find nothing wrong with his windows system (as I thought it might be a bad or disabled driver).
Any advice would be greatly appreciated.
