umm, yes you can clear a cmos that way, on some laptops. I'm wondering what he shorted tho, just incase it was something else.
"Under the keyboard or bottom of laptop - If you are working on a laptop computer the location of the dipswitch (almost never a jumper) can be under the keyboard or on the bottom of the laptop in a compartment such as the memory compartment."
I'm not forgetting the other issue, but need to know what he shorted and where it was on the laptop.
