Hi All,

I have an IBM R32 laptop. It works well for about four years. But,
recently I sometimes can't start or resume it. In such situations, If
I flip the laptop upside dwon and tap it, I may work again. I don't
why. My friend has the similar symptom. Would anybody know the problem
and how to solve it? I guess that I need to replace the CMOS backup
battery.

thanks in advance.
