I have an IBM thinkpad 600E I had the 161 and 163 error codes and unable to boot up the computer. I was checking the rams and i accidently pulled out the cmos battery wire. I didnt notice until i found this. the problem is that aven if i have the wire put back again it persists in making same error How should this be remedied ?

Go to www.ibm.com Find and download the user manual, and the "hardware maintenance manual." Do you know how to get into bios/setup? Start with the machine OFF. HOLD DOWN and CONTINUE TO HOLD THE "F1" key. WHILE STILL HOLDING "F1", turn the power on, and CONTINUE TO HOLD "F1" This will get you into the bios "setup." You should check the date, bootup order, etc, and reset. I would check the "wire" you think you reconnected---you may just not have actually reconnected it. The "hardware maintenance manual" shows you how to maintain this machine, and it explains the meaning of the error codes. This will get you started on looking for the manual: http://www-307.ibm.com/pc/support/site.wss/multiplefiledownload.do?validate=true

I do not think you fixed the CMOS battery - (backup battery = CMOS battery) According to the error codes, you have a dead backup battery and the time is not set. Makes sense? 161 (Dead battery.) 1. Go to Checking the Backup Battery 2. Backup battery. 3. System board. 163 (Time and date were not set.) 1. Set time and date. 2. System board. Numeric error codes index - ThinkPad 600/E/X 98% of the population is asleep. The other 2% are staring around in complete amazement, abject terror, or both.
