AST Ascentia J55 CMOS Battery - How to replace, where is it?

I've an old 1997 AST Ascentia J55 Laptop that the cmos battery has died (it's giving me a 'replace the system battery' error message.) I've found a few places where I can buy a replacement battery cheap enough (about $20), but I've not been able to figure out WHERE the dang cmos battery is on this computer!

In fact, honestly, I can't even figure out how to open up the dang case! I'm quite handy and comfortable tearing computers apart, but this one has me stymied.

I know, I know, it's an ancient laptop and I should probably just buy a new one...but I've been using this beast almost daily for over 10 years with no problems. It works. It does what I need it to do, and until the battery died, did it reliably and well. Although a new laptop would be nice, I don't need one! :)

Can anyone help me figure out how to open the case, and approximately where I can find the cmos battery once open and briefly, how to replace it?

Thanks so much in advance!

    I've got the same problem for an AST Ascentia M5160T, I can't figure out how to open the case to get access to the CMOS battery - just releasing the visible screws isn't enough to do it.

The key to opening the M5160T is to slide the power button cover strip:

If there are "doors" on the notebook bottom, open them and look inside. Otherwise, send a SHARP, high-resolution photo of the keyboard side (lid open) and the bottom. Send them to: I'll look at them and see if I can offer any suggestions.

How to replace the CMOS battery in an Acer Aspire laptop.

General info
All laptops have a CMOS battery. The main purpose for the CMOS battery is to store 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.

Before you start
1) Read through the owner's manual for your particular Acer Aspire laptop to determine what kind of CMOS battery you need.
2) Purchase the battery through Acer or a local or online computer parts dealer.
3) Turn the laptop off and unplug it. Also unplug any external hard drives, cameras, or other external devices.
4) Turn the laptop over (bottom facing up), then touch something metal to remove static charge.

Removal of the 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.

The battery should look something like this

Plugging the new battery in
Plug the new CMOS battery cable into the motherboard. Slide the battery partially under the laptop casing (somewhere 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.

1) Turn the laptop on.
2)Enter your BIOS (usually by pressing the "Delete" key) before the operating system loads.
3) Follow the BIOS prompts or refer to your Acer Aspire owner's manual to reset your time, date and desired system settings.

Reason: Anytime 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 to 5 seconds to correct the problem.

I replaced my AST laptop battery with a RAYDR202I Battery Ascentia M AST Laptop Battery from Batteries Plus but now unit will not power up with battery in. If I take out and power up with adapter it works...

If you have the ability to test the battery, do so and make sure it's not bad. You can try plugging your machine in with the battery in it and giving it a few hours/over night to charge the battery before trying to power on. If neither of these help, return the battery. I understand batteries plus has a pretty good return policy.

If you have to return it, I'd recommend taking your laptop with you to ensure you receive a working unit.

BIOS reset

By resetting the CMOS battery all you need to do is to teardown your laptop and have to remove and reinstall the CMOS battery. And for the replacement of the CMOS battery of your Samsung laptop just call SAmsung technical support so that they can give you the exact model of the CMOS battery and where you can have the battery. Thank you.

Ast Ascentia J series Css

with laptops, the internal battery is usually on the mother board itself. Opening laptop to get to the battery should be done by some one that knows about computer because there's alot of screws and ribbons to remove. most laptops that I have dealt with, the battery is below the key board.
