Dell dimension 3100 win xp home will not logon or go to setup/boot screen, only goes staight to black screen saying TYPE SYSTEM PASSWORD AND PRESS [ENTER] but it doesn't let you type anything. Also will...

The simplest way to remove a BIOS password is to simply remove the CMOS battery. A computer will remember its settings and keep the time even when it is turned off and unplugged because these parts are powered by small battery inside the computer called a CMOS battery. If we pull out this battery, the computer will forget alot of its hardware settings, including its BIOS password. This should not be performed on Laptops if you are not experienced working with laptop hardware.

Where are the switches on an older motherboard to alter the configuration of the motherboard


This will be found right near the CMOS battery

Locate the 3-pin CMOS jumper (RTCRST) on the system board.
Remove the jumper plug from pins 2 and 3.
Place the jumper plug on pins 1 and 2 and wait approximately five seconds.
Replace the jumper plug on pins 2 and 3.

What does the bttery control? Can I remove it for 5 seconds,then replace it and solve the ITHR checkpoint problem ?

if you are referring to the round battery on the motherboard, it controls the cmos settings remove this and your PC will not boot. yet clearing your cmos may help. look for the lil jumpers usually located near that battery and change them to reset, power on let boot then power down. then place them in the original slot.
