Changing the cmos battery on my old Thinkpad T43

Описание: 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.

Windows XP SP3 is the Operating System. Intel Pentium M 755 (2GHz). 2GB of RAM. 60GB hard drive. I don't connect to the internet with it. I do however play older games on it since its 4/3 ratio looks better with the old games.
