Where to find the CMOS battery

After a long search, I finally found the CMOS battery of my Armada E500 where I was expecting it the least: under the power buttons bar, attached to...guess what...the inverter!

Removing the cmos battery, won't address your virus problem, as you probably know it will only reset your initial boot up and not alter any software virus, unless you have an unusual bios virus.

take out the keyboard from the bottom side with a flat screw driver under it there´s a few screws take it out lift the cover and there is the battery.

Note most new computers no loger use cmos watch type batteries. They use rtc or real time clock batteries.

Had a problem with my gateway mx6025. I reset the bios password and just put spaces and then saved and exited bios. When i loaded up the computer the password screen loaded. I put in spaces and i could not get in. I tried the old password and could not get in. I called gateway to see if there was a default password and they could not help me either. After about 3 hours i finally figured out what to do. I know this sucks but I tried everything else first. (cmos password restore software would not work) Take apart the laptop and lift the keyboard. See your manufacturer info for this. Mine was here: http://support.gateway.com/s/Mobile/Q106/Blade/8511418.pdf
There is no need to remove the keyboard cable from the clip just move the keyboard aside

With the laptop open facing you, there is a round capacitor on the bottom right of the keyboard. It has a red and black wire connected. Lift up the capacitor, it is only connected to the motherboard with tape. Unplug the red and black leads from the motherboard via the white connector clip. Wait 5 minutes. Put everything back together and reboot. No more password!! Remember to reset the clock because it will be behind by 5 min.

To remove the upper plastics to get a t the cmos battery,you need to remove the 4 screws holding the screen in places. They are visible by the hinges. (That is if you have already removed the rest of the obvious screws).
