On March 25, 2012, I bought an old laptop which was the IBM Think Pad 600 X. You can read more about it on this post.
Now, what exactly happened is that it no longer works due to the error that often comes out upon turning the laptop ON. The errors are 161 and 163 which according to the User Manual; it is a problem that has something to do with the CMOS battery.
It took me a couple of hours searching various websites and forums for any similar problem. There are actually a lot of individuals with similar problem as I have. However, such concern ends up without any good possible solution.
The most suggested possible solution is to replace the CMOS battery and hope that it will work the time that you are going to power it ON. If it got stuck on the Date’s Settings then perhaps it’s the time to give up and buy your self a brand new laptop.
