SOURCE: Replacing CMOS battery - Acer aspire 3000

Before you begin, back up your data and remove the battery. CMOS Bios will be lost but will reset on restart.

    Instructions
  1. Step 1 Open the laptop computer's screen and lay it back as far as it will go. Be careful not to stress the screen and cause any damage, but press it hard if needed.
  2. Step 2 Press a flathead screwdriver under the front of the plastic bar lining the back of the laptop's keyboard. Pry the bar up slightly and hold it with one hand.
  3. Step 3 Pry up the other side of the bar with the flathead screwdriver and fully pull out the bar. Keep its ribbon cord connected and set the bar on the laptop's screen.
  4. Step 4 Remove the two Phillips screws securing the computer's keyboard. Then, slide the keyboard up and out to remove it. Again, do not remove its ribbon cord, and set the keyboard over the laptop's touch pad.
  5. Step 5 Remove the four screws securing the cover plate over the motherboard and remove it as well.
  6. Step 6 Locate the CMOS battery at the bottom right corner of the motherboard.
  7. Step 7 Remove the battery by prying it up gently with the flathead screwdriver. Then, replace the battery with a new one of the exact same specifications.
  8. Step 8 Replace all the parts in the laptop in the reverse order that you removed them. -Battery Replacement

Does this P.C have an internal battery, and if so can it be changed


If you mean a BIOS or Backup cell, yes, akk OC's have. We cannot comment on how to do it as you don't reveal the make and model.

Bl51 motherboard


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.

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.

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 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.
