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.

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!

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).

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.

Resetting the CMOS password on an Acer Aspire laptop is much more difficult than resetting the password on a desktop.
Disassembly steps vary from model to model, but on most models, you'll have to take apart the computer to access the CMOS battery.
Don't take apart the notebook if you don't have experience disassembling PCs.
After turning off the computer and disconnecting the AC adapter, take out the battery (different from the CMOS battery).
All visible screws must then be removed from the bottom of the notebook.
Remove all components stored to their separate compartments on the base of the notebook.
Turn over and open the PC. Lift up the switch cover and remove the screws securing the keyboard to the PC, if any are visible.
Remove the keyboard.
Remove the screws securing the monitor to the hinges, and then set the monitor aside.
Disconnect all visible cables connected to the motherboard; and then remove the screws from the top cover.
Remove the top cover to reveal the motherboard. Locate and then remove the CMOS battery. Leave it out of the notebook for 24 hours; then reinstall it and reassemble the Acer Aspire.
Other Options
If removing the CMOS battery fails to clear the password, or if you dont feel comfortable with the idea of opening your computer, you might be able to gain access to the computer using a backdoor password.
These special passwords were implemented to allow technicians to access locked computers. Not all models recognize backdoor passwords.
Most Acer Aspires use the Phoenix BIOS, and backdoor passwords for this BIOS include BIOS, CMOS, phoenix and PHOENIX.
All of these passwords are case-sensitive.

BIOS
Step 1:
This might not be your laptop it might give you a guide into the cmos battery
The CMOS (Complementary Metal Oxide Semiconductor) battery saves basic settings on your computer. If the date and time function on your Acer notebook isn't working, chances are your CMOS battery needs to be replaced. Separate from your laptop's main battery, the CMOS battery is about the and shape of a coin and is located inside of your computer. Changing the battery yourself isn't the simplest task that relates to your Acer, but it isn't terribly difficult either. Here's how.

Open the notebook screen until you can easily access the keyboard. Locate the plastic bar that borders the top of the keyboard. Insert the flat head screwdriver at one end of the bar and gently pry it up until you can grip the edge with your fingers. Pry the other side of the bar up with the screwdriver and pull out the entire bar, being careful to mind the ribbon cord that connects the keyboard to the computer. Remove the two screws on either side of the keyboard that secure it to the computer. Slide the keyboard up and place it to the side. Remove the four screws on the exposed metal plate that covers the motherboard and remove it. You should now see the CMOS battery in the bottom-right-hand corner of the motherboard. Remove the battery by gently pulling it up and off the motherboard. Replace it with the same model battery (available at any computer store or online). Reassemble the computer the same way you took it apart. Acer TravelMate 6592G Keyboard Replacement Guide http://tomkaminski.com/acer-travelmate-6592g-keyboard-replacement-guide

CMOS battery gateway t-1625
Remove the keyboard and the media button panel.
Remove all the screws from the underside of the laptop.
Remove the access panels.
Remove the hard drive.

There are three screws that holds the chassis together here (inside the hard drive bay). You won't be able to completely open the chassis but now you can use a flat blade (I used a small flat head screw driver) and pry the top and bottom pieces apart.

As I mentioned, you won't be able to completely take the two chassis pieces apart but you will now have enough clearance to access the CMOS battery to the right of the headphone jack (looking at the bottom).

I used a small flat head to pop the battery out. I then used long tweezers to place the new 1220 battery on the battery tray and reached around from the hard drive bay and popped it in with my index finger.

Put everything back together in the order you took it apart.

Where is the cmos battery located on the samsung r60 plus
Glad to HELP YOU!

As a rule of thumb: for laptops/notebooks/netbooks the CMOS battery is located under the keyboard. So you have to remove the keyboard in order to reach the CMOS battery.
Here I've found for you a nice video that will show you everything in detail.

GOOD LUCK!

Reset bios jumper motherboards for HP G60-519WM Notebook PC
If this is really an HP G60, the fix is really not that difficult.

Shut the system down, remove the main battery and the AC power cable from the laptop.

Remove the Hard Disk Drive cover from the bottom of the laptop (2 screws).

Next to the Hard disk you will see the CMOS battery --- it is about the size of a penny and covered in dark tape. Two wires lead from this CMOS battery to a plug about 1.5 inches away. Disconnect this plug, wait 5 minutes, and put everything back the way it was.

Restart the system ---all CMOS settings and BIOS passphrases will have been reset.

My ASI-CL-15 Laptop will boot up, then shut down after a few minutes. When trying to reboot, the fan comes on and runs for about 3 seconds then stops. This happens with the hard drive in or out. After pressing the stop/start button for a few seconds, I c an try to reboot again (completely power dcown). If I wait for about 20 minutes, it will reboot but the problem starts all over again. Somemtimes, upon trying to reboot, the screen will blink on & off with the windows screen appearing.
