Where is cmos battery in acer 5600


Disconnect the power cord from the laptop and remove the main battery.
Open the laptop computer's screen and extend it as far back as it will go. Be careful not to stress the screen and cause any damage, but press it hard if needed.
  1. Press a flat head 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.

  2. Pry up the other side of the bar with the flat head screwdriver and fully pull out the bar. Keep its ribbon cord connected and set the bar on the laptop's screen.

  3. Remove the two Phillips screws securing the computer's keyboard. 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.

  4. Remove the four screws securing the cover plate over the motherboard and remove the plate as well.

  5. Locate the CMOS battery at the bottom-right corner of the motherboard.

How to change a cmos battery on a Sony PCG-TR3A


It is a button battery under the keyboard. Just be careful not to break the battery holder.

I am looking at the mother board of an Acer aspire one notebook computer. I need to view a diagram of the cmos battery to remove it to resolve a password problem.


the CMOS battery is usually located/accessed by removing the keyboard.

Acer don't seem to want to share that kind on data so here's some stuff which may help, but its for an 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

This didn't quite do the job, the Aspire was a bit of a so and so. So here's how I changed it on a 3000:-

Acer Aspire 3000 CMOS battery replacement.
------------------------------------------
Before going any further, you need to know that Acer have done you no favours, this laptop is especially designed to raise revenue for Acer and other laptop technicians. This is a fiddly task and you could do with 3 hands.

1) The cmos battery is on the motherboard about half way down the left hand side, turn your laptop upside down and you should see a locking screw for the optical drive, its just inboard from that screw under the bottom cover plate.

2) The motherboard on the ACER Aspire 3000 is upside down, so it faces the bottom plate or table it sits on.

3) The battery is a 3v Maxell ML1220 or equivalent. About the size of your little finger nail.

----------------

Before dismantling your laptop, disconnect the power supply and remove the battery. Then read these instructions thoroughly, make sure you are happy with what you are going to do.

1) Ensure you've got plenty of work space, a plate/dish for the screws and I like to work on a newspaper so I can swivel it all around without scratching anything.

2) Close the laptop, remove the screws from the 3 hinge covers.Open laptop until flat, gently prise off the top backplate. It includes the hinge covers, buttons etc and continues down as far as the top of the keyboard.

Start at one end gently teasing/prising it upwards until it comes free, there are no connections.

3) Removed the 2 screws holding the keyboard down, lift the keyboard gently and place it upside down on the mouseplate, don't break the ribbon connector.

4) Remove the three remaining screws from under the keyboard, one of these is a second optical drive lock screw. Replace the keyboard in its bed, close the laptop and turn it over.

5) Remove all screws and covers from the bottom plate. Remove HDD and the Optical drive, but leave CPU, RAM and WIFI in place. There are 2 further screws one in the battery well and one in the HDD well,remove those also.

6) Very gently, from the side of the laptop where the DVD drive sits, prise the bottom plate away. It won't come away completely. There's a speaker connector at the front at the other end. Bear in mind you'll probably need the lid open as well.
7) Once you have the bottom plate prised far enought apart, you should be able to see the battery, on the motherboard about half way down just about where the back of the DVD Drive would sit. Its in a white plastic mounting, and should be able to flick it out with your finger nail or a screw driver. It may be a good idea to get a second pair of hands to hold the laptop while you replace the battery.

Remember the negative side of the battery sits in the mounting, Positive side upwards.

8) Re-assemble laptop, reverse order to dismantling.
9) Keep fingers crossed whey you re-boot.



Good Luck.

Where is the location of the Cmos battery for my


You really need a service manual to try & locate the CMOS battery. With laptops the CMOS battery can be different on each model. These are often located on the motherboard below the keyboard, but a service manual should help you.

The CMOS battery is located underneath the keyboard as well as one of the two memory slots. To get at it, you have to remove the “Hinge Cover” and then the Keyboard.
To remove the “Hinge Cover” (The hinge cover has the ON/OFF button) follow these steps:
1) Remove the battery and AC power.
2) In the battery bay you’ll see 2 small Phillips screws. Remove these screws.
3) Turn the laptop right side-up and using a small screwdriver, pry up on the notch on the right side of the hinge cover.
4) Lift and remove the hinge cover from the laptop.
5) Carefully lift the keyboard and gently slide it towards the LCD. (CAUTION! The keyboard is connected to the motherboard with a ribbon cable. Be careful not to damage the cable on the underside of the keyboard.)
6) The CMOS battery is located on the right side of a small white ribbon cable. It’s about the size of a small coin.
Hope this helps.
