The jumper is normally close to the CR2032 battery.

It will also have CMOS J1 or something like that written below it. Possibly CMOS RESET

Some Acer Aspire desktop models come with a jumper that is used to clear the password and other settings stored on the CMOS. This jumper is located on the motherboard and is often found next to a label such as "JBIOS1" or "CLR_CMOS." To clear the CMOS using the jumpers, turn off the computer, disconnect the power (http://www.ehow.com/info_12176121_acer-aspire-password-removal.html#) cable and remove the case cover. Remove the jumper shunt from pin 1 and pin 2; then place the shunt on pin 2 and pin 3. Return the shunt to its initial position after 10 to 15 seconds. If the Aspire doesn't come with a jumper to reset the CMOS, the CMOS can be reset by removing the lithium coin-cell battery instead. Removal is accomplished by pushing down on the tab securing the battery to the motherboard and lifting the battery out of its slot. Leave the battery out for 24 hours, and then return it to its original position with the positive sign facing up.


I assume no liability for the accuracy, completeness or topicality of the following instructions. These instructions describe only in general, how to erase the CMOS on PC-Mainboards and Notebooks. It may be completely different for your computer!



the jumper will look like that little green plastic plug in picture,you just move it over to the pin that is free and the pin next to it,but remember to move it back to original position.
