It is in the middle of the mother board. It looks just like a watch battery.

All laptops have a CMOS, or "Complementary Metal Oxide Semiconductor," battery.
The main purpose for the CMOS battery is to keep the system time, date and BIOS settings even if the computer is turned off or the main battery dies.
Individual Acer Aspire laptop models differ somewhat, but the general steps are the same when replacing a dead CMOS battery.Preparation

Read through the owner's manual for your particular Acer Aspire laptop to determine what kind of CMOS battery you need.
Purchase the battery through Acer or a local or online computer parts dealer.
Turn the laptop off and unplug it.
Also unplug any external hard drives, cameras or other external devices.
Turn the laptop over (bottom facing up), then touch something metal to remove static charge.
Removal
Remove the Phillips screws that secure the motherboard cover (refer to your owner's manual if necessary), then release the cover from the clips on the bottom of the plastic casing.
Lay the cover aside, then locate the CMOS battery cable on the right side of the motherboard. Unplug the cable, then remove the battery.
Installation
Plug the new CMOS battery cable into the motherboard.
Slide the battery partially under the laptop casing to hold it in place, then align the cover with the slots on the bottom of the laptop housing.
Replace the screws, then turn the laptop back over.
Settings
Plug the laptop in and turn it on.
Enter your BIOS (usually by pressing "F1," "F2," F10" or the "Delete" key) before the operating system loads.
Follow the BIOS prompts or refer to your Acer Aspire owner's manual to reset your time, date and desired system settings.
BIOS Reset
Any time the CMOS battery is unplugged for more than a few seconds, your BIOS will be reset to the default manufacturer settings.
If you make any changes to the BIOS that cause problems with your Acer Aspire, unplug the CMOS battery for 3-5 seconds to correct the problem.

How to replace the CMOS battery in an Acer Aspire laptop.


General info
All laptops have a CMOS battery. The main purpose for the CMOS battery is to store the system time, date and BIOS settings even if the computer is turned off or the main battery dies. Individual Acer Aspire laptop models differ somewhat, but the general steps are the same when replacing a dead CMOS battery.

Before you start
1) Read through the owner's manual for your particular Acer Aspire laptop to determine what kind of CMOS battery you need.
2) Purchase the battery through Acer or a local or online computer parts dealer.
3) Turn the laptop off and unplug it. Also unplug any external hard drives, cameras, or other external devices.
4) Turn the laptop over (bottom facing up), then touch something metal to remove static charge.

Removal of the CMOS battery
Remove the Phillips screws that secure the motherboard cover (refer to your owner's manual if necessary), then release the cover from the clips on the bottom of the plastic casing. Lay the cover aside then locate the CMOS battery cable on the right side of the motherboard. Unplug the cable then remove the battery.

The battery should look something like this

Plugging the new battery in
Plug the new CMOS battery cable into the motherboard. Slide the battery partially under the laptop casing (somewhere to hold it in place), then align the cover with the slots on the bottom of the laptop housing. Replace the screws then turn the laptop back over.

Finalizing
1) Turn the laptop on.
2)Enter your BIOS (usually by pressing the "Delete" key) before the operating system loads.
3) Follow the BIOS prompts or refer to your Acer Aspire owner's manual to reset your time, date and desired system settings.

Reason: Anytime the CMOS battery is unplugged for more than a few seconds your BIOS will be reset to the default manufacturer settings. If you make any changes to the BIOS that cause problems with your Acer Aspire, unplug the CMOS battery for 3 to 5 seconds to correct the problem.

How can I remove BIOS Password from Acer TravelMate 230/280 MS2132 laptop?


Use a Backdoor Password
  • 1

    Go to the Technibble website and locate the manufacturer of the BIOS for your computer. Write down the backdoor passwords that are listed.

  • 2

    Restart the computer and press the "F2" key to access the BIOS.

  • 3

    Enter one of the backdoor passwords to see if you can access the BIOS. Repeat this step until you find a password that works--but keep in mind, sometimes three wrong guesses will cause the computer to lock up.

  • 4

    Change the password for the BIOS to something else, then exit and restart the computer.

  • Remove the CMOS Battery
  • 1

    Unplug the computer from the wall outlet or power strip. Remove the screws on the back of the case that secure the side panel. Slide the side panel off and then locate the round CMOS battery that is attached to the motherboard.

  • 2

    Examine the battery to see how it is attached to the motherboard. Pull on the latch to release the battery and then remove it from the motherboard.

  • 3

    Wait about 20 to 30 minutes for the electricity in the capacitors on the motherboard to discharge or dissipate.

  • 4

    Set the CMOS battery back in the motherboard. Set the side panel back in place and the plug the power cord back in.

  • 5

    Restart the computer and press the "F2" key to access the BIOS

    This could mean two things: a problem with the cmos battery or the motherboard itself. Try to remove the cmos battery first and install. If not,then replace the cmos battery.

    How do I replace a dead cmos on acer 4520LCi travelmate laptop? The laptop no longer keeps track of system time when shut off completely. Can you tell me the exact location of the cmos so I can be able to...


    Hi,

    what you replace is not the CMOS, but the CMOS battery.

    On an ACER from those years the CMOS battery looks like a coin, or a coin wrapped in plastic and connected to the motherboard.

    On most models from same series the battery is located on the lower side of the motherboard, like on picture below:

    On some model the battery may be located underneath the keyboard.

    Here disassembly instructions for a similar model.

    I get Error 173 and 163 when I start my thinkpad. What can I do?


    The Thinkpad POST error code you are getting are :-
    163 - CMOS error, clock is not updating
    175 - Bad EEPROM CRC
    This is caused by either a faulty EEPROM chip or a flat CMOS battery.
    Replacing the CMOS battery and go into the CMOS/BIOS configuration and set the Date and Time etc.
    If the problem is still there then it is a motherboard problem and depending upon the age of the laptop it may not be worth repairing.

    Clock not keeping correct time


    The CMOS battery keeps the laptop configuration stored in the CMOS chip and the main battery has no effect on the CMOS.
    If the date and time drift off, it indicates the CMOS battery is nearly flat and needs to be replaced.
    If you had ticked the Daylight saving box in the Time Zone tab in Control Panel - Date and Time setting then the time would automatically adjust for Daylight saving.

    Bios lock, ERROR CODE 0271


    Hi,
    Error code 0271 - Date and time error. Neither the date nor the time is set in the computer.
    Run BIOS Setup Utility to reset the time and date
    It sounds as though your computer has the wrong time in the CMOS. The CMOS (Complementary Metal-Oxide Semiconductors) is the chip that holds the basic startup information for the BIOS, system and its peripherals while the system is turned on and off.

    If you can get into the BIOS check the date and time settings and make sure they are correct.

    It may also be a case of the CMOS battery going out. When this happens your computer will tend to not keep the correct time. They are cheap and relatively easy to replace. Before buying a new batter your can try to take it out and let it sit for about 10 minutes or so to reset the CMOS and then go put the battery back in and go into the BIOS and reset the clock.

    Hopefully taking the batter out or replacing it will get past your lock icon asking for the password. Just search for CMOS or BIOS default password for your brand of laptop.
