2. By the CMOS battery - Some manufactures place the jumper to clear the CMOS or BIOS password by the CMOS battery itself.
3. By the processor - Some manufactures place the jumpers by the CPU of the computer.
4. Under the keyboard or bottom of laptop - If you are working on a laptop, the location of the dip switch can be under the keyboard or on the bottom of the laptop. It is usually located in a compartment such as the one that contains memory. (Laptops almost always use dip switches, not jumpers.)
