A105 MB... I was attempting to replace a cmos battery, when I noticed it was clipped on top and bottom, so I decided to close case and get more info on this issue. But now, the power and battery lights are the only thing tyhat comes on. What can I do? Could it be the MB or CPU failed? Urgent!!!

Acer Aspire 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.

FOLLOW Anti-Static Precautions

Anti-Static Precautions:
Your body carries Static electricity. Static WILL fry out (Short Circuit), the delicate hardware components inside a computer.

Relieve your body of Static BEFORE, reaching inside your unplugged from power, computer.

Computer on a table, computer unplugged from power, computer case open;
TOUCH an unpainted surface of the metal frame, of the open computer case.
This action will relieve your body of Static.

IF, you leave your computer in the middle of working on it, be SURE to Touch the metal frame again, upon your return.

Motherboard installed in computer case, the CMOS battery, (BIOS battery), is located at the Bottom/Right corner; above the four Red SATA connectors.

The CMOS Battery holder has a lock clip on one side.
This clip is eased to the Outside edge, in order to release the CR2032 CMOS Battery. (A type of watch battery)

Suggest use a stiff plastic object to release lock clip.
Most however, use a small Jewelers flat tipped screwdriver.

You want to JUST press on the Lock Clip itself.

The battery should just pop-up a little. Then a fingernail is used to lift that side up, to access the battery.

When reinstalling remember the Positive ( + ) side ALWAYS goes UP.

After locking the new battery in, make sure no cables were accidentally pulled loose.
Also just for ease of mind, try to push the Ram Memory module/s in ('Stick') more. Make sure the Locks on both ends are locked in place.

A lot of times the Ram Memory modules get bumped loose, accidentally.

Close the computer case. Plug computer back into power.
WAIT 1 minute, turn the computer on.

Go to the taskbar at the bottom of the Windows screen, and to the right.
-> Right-click on the Time.
Now reset the Date/Time to what it should be.
Need guidance on that post back in a Comment.

Yes there is. What you need to do is remove the backup battery on the motherboard (disc shapped mercury battery).This will default your BIOS

Hi,

The CMOS battery you need is a CR2032 3V battery. You can get them from places like Radioshack, PC World or any good computer store.

Click on the link that I have provided below, it takes you through to Radioshack where you will see the battery for yourself>>>>>

just remove the cmos battery

the bios stores the password and the cmos battery provides it power to store it

if you remove cmos battery the bios reverts to factory settings and the password is removed

cmos battery is different than the laptop backup battery

cmos battery is found inside the laptop case on the motherboard, you will have to open the laptop to remove the cmos battery

Hi bridey28, when you replaced the cmos battery & the bios did not maintain the correct time than the cmos is not at fault. More likely its your power supply. The cmos receives its power (Recharge) from the power supply. An average cmos battery should last for 5 years. The fact that you attempt to power up the PC & you have to wait, points to a power supply problem. Not a bios problem.
Bios corruption is rare, unless you have tried to flash the bios & it failed. Replace the power supply before attempting flashing the bios. Every manufacture warns against flashing the bios. Only flash the bios if your 100% sure that it will correct a bios malfunction. If the issue presist after replacing the power supply, Intel has instructions of (How to flash the bios) on their site.
Here are the instruction from Intel for your MB model number.

You'll need this link to download the bios file;

Good luck bridey28!
Need more info, post here.

The battery is a button type battery, you can release by pressing the metal clip to the side and the battery should pop up, if not use a thin blade screw driver to lift the battery up whilst pressing the metal clip to the side, Do not hold the battery (top & bottom) with metal tweeters, you will create a short circuit condition.

Try removing the main battery and the CMOS battery (ie the battery on the mb). If you don't want to wait for 1/2 hour for the CMOS to discharge then short out the CMOS battery connections with a bent paper clip.
Then without instralling both battery, power up your laptop, you should then get into the BIOS, power off and re-install your batteries.

Hi,
Look for the CMOS Battery under the keyboard, if not near the memory at the bottom of the laptop, there are screws to remove.

Hope this Fixya an idea where the battery is kept.
