A CMOS battery usually looks like a coin. It is a silver lithium battery, similar to wrist-watch battery and is usually placed near the BIOS chip.

Some motherboards - especially laptops - have a different kind of battery.
They are simply a capacitor on its own board attached to the motherboard.

So in order to clear the CMOS you need to remove the capacitor and re-solder it to the motherboard, which you don't want to do without some electrician skills.
Sorry...

Cmos battery


Replace an Acer Extensa CMOS Battery
CMOS batteries allow you to store basic settings on your laptop.
If you notice certain features on your computer do not operate correctly, such as the computer clock, you may have to replace your CMOS battery.
This battery sits on the interior portion of your machine and measures about the size of a dime.
If you have a screw driver and know how to work with your hands, you can replace the CMOS battery on your Acer Extensa computer.

Open the screen of your laptop until you can view your keyboard clearly.
Find the bar that consists of plastic on the upper portion of your keyboard.
Place your screwdriver on one end of this bar and slowly ease it up until you can grab its edge with your finger.


Pull the opposite side of the bar in the upward direction with your screwdriver.
Then, ease out the whole bar.

Take out the screws on the side portion of your keyboard.
Pull your laptop keyboard upward and put it on a soft surface such as a bed or pillow.

Take out the four screws from the steel plate, which covers the motherboard of your computer, and take off this plate.
This allows you to view the CMOS battery, which sits on the lower right portion of your motherboard.

Pull the CMOS battery up from the motherboard and take it off.
Insert a new CMOS battery, which you can buy at a local computer store.
Put the parts of your computer back in the same manner as you took them off.

Computer was locked


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

How do I replace the cmos battery


http://www.tim.id.au/blog/tims-laptop-service-manuals/#toc-acer

Drop down to the 'paragraph' that starts with - Travelmate 200.
(200 in Blue)
Go down to the 7th line (5730 in Blue), scroll across, and click on -
6493 in Blue.

This is a PDF file. The computer you are using now has Adobe Reader on it, which uses PDF files.
After you click on the file name (6493) it may take up to 30 seconds, before the first page comes up.
The file is downloading in the background.

The CMOS Battery, or also known as the RTC Battery, (Real Time Clock), is on the BOTTOM of the motherboard.

http://www.aliexpress.com/item/For-acer-TravelMate-6492-6492G-notebook-motherboard-MBTLN0B001-Tested-ree-Shipping/555541838.html

Scroll down a little to the two Large views of the motherboard;
1) The first view shown is the Bottom side of the motherboard.
Has the blue -
For Acer Travelmate 6942 6942G notebook motherboard MBTLN0B001 and tested+ree, above it.

Yes. TravelMate 6492, not TravelMate 6493. The RTC Battery is still in the same place.

Above the pink processor socket......see the Yellow round object?
It actually has wires coming from it, that end in a small white connector.
Not the same color, not the same series, but gives you a better look at this type of RTC Battery setup,

http://www.ebay.co.uk/itm/ACER-TRAVELMATE-6292-SERIES-6292-812G25Mn-CMOS-BIOS-BATTERY-/230795196555?pt=UK_Computing_Other_Computing_Networking&hash=item35bc77388b

There is a little round watch type battery in that Yellow, and that Black plastic 'bag'.

Losing date, and time? Replace CMOS/RTC Battery.
Need to reset, or wipe out a BIOS password, or HDD password?
(HarDDrive)
Not THAT way.

Go to Page 53. (Adobe Reader page number box at top)

Page 168 - Bottom View of motherboard - Number 13 in the chart -
CLRP2 - CMOS clear
(Clear CMOS jumper)

Instructions on Page 169

The Service Manual doesn't show the location of the CMOS battery.
DOES state it in Troubleshooting / Random Loss of BIOS Settings Page 148 at the Bottom.

Just an average laptop disassembly video I found. Skip to 3:40 or so to start.
You SHOULD wear an ESD wrist strap, and have it's aligator clip attached to a good ground source.
He is AT least working on a wood table top.

Perhaps some of these Acer pictorial guides will also help,

http://www.insidemylaptop.com/category/1-acer-laptops/

Could I be wrong about the CMOS Battery location?

Moi?

Yes.

Look down in the Battery Compartment for the CMOS Battery, or in a small hidden panel down in the Battery Compartment.
Also look on the top of the motherboard, once the Palm Rest Cover (Top Cover) is removed.
