I have an Acer 5610-2328 notebook. I need to clear CMOS. How?
I can't find the CMOS battery. I have taken the top plastic off the machine and some of the bottom plastic. I have a CMOS bios password trying to clear it. I can't find any information on which jumpers to bridge if any. Help, please! :)

Find the bar that consists of plastic on the upper portion
of your keyboard.
Place your screwdriver on one end of this bar

with your screwdriver.
Then, ease out the whole bar.

a local computer store.
Put the parts of your computer back in the same
manner as you took them off.
Resetting the CMOS password on an Acer Aspire laptop is much
more difficult than resetting the password on a desktop.

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

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
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.
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.

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.
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,
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,
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.

first remove your battery and try to switch on your laptop with good power adapter if still have the same issue ?? just remove your memory and reinstall after clean your memory if still have the same issue ?? remove your memory and cmos battery and switch on it with a good power adapter.after 2 minute you can re install back your memory and cmos battery and try to switch on it.
You need to open your notebook remove first the battery and all screw at
the back of your notebook. You can see there a CMOS battery together
with the CMOS jamper. Just read it you can read CLRSCR which means clear
cmos, just pull it with in 10 seconds and insert it back. Now you are
done to reset bios.
The RTC battery is inside the laptop connected by a two wire connector. it generally resembles a large button type battery. The laptop will have to be taken apart and the top panel removed to be able to get to it.
Unplug the power, remove the battery, check the battery compartmnt, there should be a small screw or slot and a yellow or white or black plastic encased thin watch battery with red and black wires, you need to detatch it and attach back after 10 seconds. It will clear the CMOS settings including password.
