Thanks Steel Breeze!! I did exact as you suggested and it was easy. I used a Dremmal tool to cut a squre holes. You can actaully see part of the battery (CR2032) through one of the existing holes.

Re: disassembling ASUS Degatto Laptop

The cmos battery is held beneath the plastic shelf directly below the hard-drive. You will either need to force the shell apart enough to get to it; or, do like I did and remove the HD and carefully use an exacto knife to cut a small square out of the HD shelf. Just remember to cit slowly and let the knife do the work, not forcing it through the plastic! Patience grasshopper will bring great rewards! Hope this helps! J

Re: disassembling ASUS Degatto Laptop

I had the same problem looking for the CMOS battery and literally removed every possible screw I could find. The upside was that I gave every nook and cranny a thorough cleaning (there was a considerable amount of crud built up especially on the heat sink and fan) but I still couldn't locate the damn battery compartment. Steel Breeze's solution was right on the money and spared me the hassle of taking apart the LCD panel. I used a Dremel tool to cut a semi-circular flap around the battery, which I slipped off with a pair of forceps and replaced with a new one. Now I'm one happy camper!

It's difficult to say but you will need to remove the underside screws and also maybe even the keyboard as it's often attached to the base. The cmos battery could also be behind the screen.

Where is the CMOS battery on an asus u50f laptop? I am stuck on the logo screen and need to reset

Try this site scroll down a bit:
Have you tried to do a system restore? Maybe a "Cold Start", remove the AC plug, remove the AC plug, hold doen the on/off button for 10 seconds, replace battery, plug into AC outlet, re-boot. If that fails try again this time repeatedly tapping the F-8 key so you have options to restore/recovery etc.

How to reset BIOS password on a laptop.

On a Laptop often you have to disassemble the computer to remove the battery or jump the CMOS reset.
On some laptop, like many Dells, and thinkpads the battery can be accessed from one of the slots at the bottom, and it is located deep at one side of the slot.
More commonly battery is located on lower side of the motherboard, and to access it you will have to remove the motherboard.
Better getting schematics before disassembling the laptop.

Do not disassemble the laptop unless you have done this operation several times before, and you have practice.

Before disassemblying remove battery and unplug the AC adapter.
Do not short any pins unless you are sure that you are jumping the CMOS reset pins, even without main laptop battery you can still damage components touching here and there.

The best way to erase CMOS is removing the laptop battery for one minute, thn pputting it back.

This will reset CMOS to factory and erase BIOS settings.

Round silvery looking object. Go straight down from the red arrow to the far left.

That is how to access the CMOS battery.

Sche matics for a toshiba satellite A205iskaa la-3481p motherboard so i can reset the bios password or remove it.

Hi schollmd


On certain laptops, it is possible to delete the BIOS Memory by temporarily disconnecting the CMOS/RTC Battery before reconnecting it and reassembling the laptop.

Sometimes this requires almost total disassembly of the laptop.

So no damage is done during disassembly and the correct component positions and cable connections are restored during reassembly, this is a job best done by an experienced repair technician.

While yellow is a common colour, the CMOS/RTC Battery can also be encased in blue, brown, black or green plastic.

On some models the CMOS/RTC Battery is accessible without disassembly, via the Wireless Card compartment underneath the laptop.

On other models, disconnecting and reconnecting the CMOS/RTC Battery is ineffective in clearing the BIOS Memory Cache because nearby capacitors store the data if the Battery is removed. Two contact points on the motherboard have to be bridged in order to dissipate the charge from the capacitors to reset the BIOS.

The Step-by-Step Disassembly Guide for this model series of laptops can be viewed here:

Need to unlock bios password on dell laptop, have service tag # and ends in 59b


If you have loast the password, to reset the BIOS password you need to remove temporarily the CMOS battery , so to reset BIOS settings.

Some model may be using NV Ram, in that case removing the battery is not enough.

The battery is located on the lower side on the motherboard.

On many DELL models the battery can be accessed from the side of DVD slot, battery slot, or RAM slot, without disassemblying the laptop.

On some model you may need complete disassembly (eg. Dell Le series).

The battery looks like a couple of coin batteries wrapped in plastic.

Before disassemblying or removing covers, always unplug adapter and remove battery.

On Dell Inspiron 8500 the battery can be accessed from a side , after removing the primary battery.

I think Dell 8500 can be set to use NV Ram to store the password.
In this case the problem cannot be solved removing primary battery, then accessing and removing CMOS battery for few minutes.

If you still cannot reset you have two way out.

Disassemble completely and access the NVRAM microswitch, or contact Dell and get master password.

You can also try one of this standard Dell factory CMOS password:

CMOS replacement for ASUS d1

Comment by sandrew, posted on Nov 12, 2006 I'm sorry but I dont have any personal experiences with your particular laptop, but the lcd's are generally held in with 1 screw in each corner normally covered by a rubber bung hiding the screws, I would be very carefull not to disconnect any wires behind the screen, if yor not sure take it to a qualified repairer. You will probably have to remove the top panel just below the hinges as they may be held in underneath
