Acer TravelMate 330T CMOS Battery Replacement

I've got the correct battery (CR1220), but I'm having trouble getting case apart. I removed the HD, Ethernet Card, and the main power pack, loosened all the screws, gently pried the case all around, but it appears to be hung up along the front edge. What's the trick?

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

Low battery warning message on boot up

I'll give you the info for the cmos battery but afterwards observe any other issues with your notebook. Your notebook is not new anymore and may need other servicing besides a new cmos battery.

It should be housed driectly undeneath you notebook on a panel you can remove that houses the ram.

If you still cant find it, you may have to physicaly take apart the unit. I would search under the keyboard and all four corners of the motherboard and center. Just in case.

Let me know how it goes.

P.s: Be very careful If you are not use to opening up notebooks then I suggest taking unit to a professional for them to replace the cmos battery.

Forgot password for Acer TravelMate 240

RTC battery inside somewhere to keep the password of your computer.

Try to find the RTC battery (acer almost used cr1220 ) and take it off from socket wait 10 seconds and put it back again .

You need to disassemble the unit ~take the keyboard and heatsink plate off ~you will see the RTC battery.

You may type cr1220 to search the picture of RTC battery on line easy.

Good luck.

Acer Travelamte 515 TE cmos battery replacement

All older laptops have the CMOS/RTC battery under the keyboard and usually not in easy access as laptop theft was an issue from day one (password reset). After the keyboard is lifted then either look to the front or rear for two little twisted wires connecting the battery to the motherboard. Some older laptops even have two. And since Acer is a less than supportive manufacturer with a perpetually busy website you might even try looking on EBay for a parts only offering that shows pictures of the motherboard.

Cmos battery for C110 TCI

The CMOS Battery is behinf the main battery behind a platic shield. The shield is relitivly fragile and glued around the edges. Care should be used removing it to prevent ripping. The battery itself is 3" flat pack glued to the case. Mine was wrapped in a black heat shrink with two wires exiting.
The connector is under the keyboard. You will need to remove the 6 scres from the bottom of the case to release and remove the keyboard. The keyboard ribbon cable is attached through a ZIF socket. Be sure and release the cable before removimng the keyboard. Youll have to trace the CMOS battery leads to determine the correct connector.
I found a Maxell ML2032 rechargable battery. Unfotunatly all the 3" flat pack batteries I have found are LITHIUM ION and not rechargeable. If I find a replacement I will post the information.
