Cmos battery and IBM thinkpad 600

I have had problems booting up my old thinkpad. I did some research, and most people think its the cmos battery, which is cheap. I would like to know how I would change it out.

In the past, I thought that I had these problems because I did not turn my TP on for a long time. By leaving it on, it seem to fix the problem, but not now.

I get the following mother board errors

DEV 001
ERR 0091
FRU 3610

Here is the cmos battery I might need. I think I might need to replace the main batter after that.

Thanks, Whicky1978

 

Usually a pc will boot with cmos battery that is low have you had problems with the OS loosing the time and date. How old is your Think Pad

 

My thinkpad is a Pentium II, and it does lose track of the time and date.

 

Thinkpad 600

 

Well looks like you know the problem next step is to replace the battery.If you have the manual look in their if not check their web site.

 

There are only a few panels that I can open on the thing, maybe I will find it.

 

Wow I really this computer. I searched IBM Thinkpad and my username and came across this old thread. I was trying to remember which Thinpad I had. some consider the 600 to be one of the toughest ever made
