Changing the cmos battery on my old Thinkpad T43…

I went school to work on computers. I did get a Associates in Computer Systems but there isn’t much of a job market lately due to the smart phones. Anyway I had this IBM Thinkpad for about 15 years. Other than the cmos battery the laptop has been pretty solid. So in this video I replace the cmos battery and troubleshoot. I find out I disconnected the fingerprint reader and touch pad connection.
