HOW DO I REPLACE THE CMOS BATTERY ON MY GATEWAY SOLO 1200?

SOURCE: Gateway 450rog cmos battery

The CMOS battery is located on the motherboard, just under the bottom left side of the keyboard, by the letter 'V". It looks like a clock battery, marked 3V (volts). The battery comes out of its "cage/connector" by gently lifting it with a small flat screwdriver. Replacement CMOS batteries are inexpensive and readily available at any computer shop. Hope that helps
