Hi bonnell

You don't say what your reason is for wanting to access the CMOS Battery. If you add a comment or a clarification request to this question, stating your objective, then maybe you can get alternative advice on a how to solve the problem you're having with this netbook.

The CMOS Battery in most laptops, notebooks and netbooks cannot be accessed without dismantling the entire machine and exposing the underside of the motherboard.

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.

See below for the location of a CMOS Battery in this notebook. The CMOS battery is the rounded, blue object in the centre of the image near the front.

I hope this helps.

SOURCE: cmos jumper location fujitsu amilo pi 3540

Yep, no jumpers. This isn't a desktop computer motherboard.

You can try to remove the RTC Battery.
(Real Time Clock battery. Also known as CMOS battery)

Problem is with this age of laptop there is a Capacitor, or capacitors, that hold a residual charge. Enough to keep a BIOS password FOREVER.

Usual method would be to jump across two tiny pads, (Copper?)
Location?
Dunno.

Sometimes under a piece of Mylar plastic, under the Wireless Module.
Sometimes under the Ram Memory module/s. ('Stick')
Sometimes on the bottom of the motherboard.
(THIS deters lazy thieves, lol!)

Best bet is to take it to an authorized Fujitsu representative, and your;
1) ID
2) Credit/Debit card
3) Proof of purchase

The rep will obtain a Master password. The rep KEEPS the master password.
The rep will then rest the password to one you want, or set it to NO password.

Use the software available on the internet?

Hmmm, let me see,....
Give my credit/debit card info, to an entity that is going to give a master password, to someone they DO NOT even know, and could have stolen the laptop.

Yep! That sounds like NOT!

joecoolvette

Hello, you can download this tool here:

The official method is to contact Dell Technical Support. Dell Technical Support will request the Service Tag and Express Service Code from the bottom of the Latitude. If the current user is not the original Latitude owner, Dell will transfer the used Latitude's registration from the original owner with only the Service Tag and Express Service Code from the tag on the laptop.

  • For most Dell Dimension desktops, the steps to reset a BIOS password and clear all CMOS settings are:
    • Locate the 3-pin CMOS password reset jumper on the system board.
    • Remove the jumper plug from pins 1 and 2.
    • Place the jumper plug on pins 2 and 3 and wait approximately 5 seconds.
    • Replace the jumper plug on pins 1 and 2.

Try the backdoor password: Dell

The another method is: by Using the Motherboard Jumper: In most motherboards CMOS battery is soldered, which makes it difficult to remove the battery. In this case we use another method.
Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don't have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.
When you find the jumper, look carefully. There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, is remove the jumper and join the center pin to the opposite pin. e.g. if the jumper joins center pin to left pin, then remove it and join center pin to right pin. Now wait for a few seconds and then again remove the jumper and join the center pin to left pin.
Make sure to turn the PC off, and remove the battery and power cord
( if it is a laptop ) before you continue.

Here is a picture how it looks like:

The default setting is:pin 1 to 2, to clear cmos: 2 to 3.

Best of luck :-)

Clearing cmos password or cmos clear jumpoer location.... where can i find?


This information is intended for experienced users. It is not intended for basic users, hackers, or computer thieves. Please do not try any of following procedures if you are not familiar with computer hardware. I'll not be responsible for the use or misuse of this information, including personal injury, loss of data or hardware damage. So use it at your own risk.

A. By Using Software:
I have found that using Dogber1's Dell Password generator is a great solution to this problem. It is free and takes approximately 10 seconds to download from his site.

B. By Using the Motherboard Jumper:
In most motherboards CMOS battery is soldered, which makes it difficult to remove the battery. In this case we use another method.
Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don't have the manual then look for the jumpers near the CMOS battery.

Now wait for a few seconds and then again remove the jumper and join the center pin to left pin.
Make sure to turn the PC off before opening the cabinet and resetting the jumper.

Good luck

Not only the chip inside the motherboard can do it. All you have to do to DISABLE Jumper Setting near by Lithium CR2032 Battery or else in the motherboard by removing in a second (10 secs.) Then put back again and the BIOS were back into default setting.

How do I reset my lost bios password for Dell Precision M70


Hi,
If you cannot access the machine after if has been powered up, it is still possible to get past the BIOS password. The BIOS password is stored in CMOS memory that is maintained while the PC is powered off by a small battery, which is attached to the motherboard. If you remove this battery, all CMOS information (including the BIOS password) will be lost. You will need to re-enter the correct CMOS setup information to use the machine. The machines owner or user will most likely be alarmed when it is discovered that the BIOS password has been deleted.
On some motherboards, the battery is soldered to the motherboard, making it difficult to remove. If this is the case, you have another alternative. Somewhere on the motherboard you should find a jumper that will clear the BIOS password. If you have the motherboard documentation, you will know where that jumper is. If not, the jumper may be labeled on the motherboard. If you are not fortunate enough for either of these to be the case, you may be able to guess which jumper is the correct jumper. This jumper is usually standing alone near the battery. If you cannot locate this jumper, you might short both of the points where the battery connects to the motherboard.
If all else fails, you may have to clear the BIOS password by resetting the RTC (Real Time Clock) IC (Integrated Circuit) on your motherboard.
The BIOS password may be cleared from a Dell Optiplex by removing the password jumper (PSWD) from the motherboard.
The location of the password jumper on a Dell Optiplex motherboard can be found by reviewing the Optiplex User Guides.
For most Dell Optiplex desktops, the steps to reset a BIOS password and clear all CMOS settings are:
  • Locate the 3-pin CMOS password reset jumper on the system board.
  • Remove the jumper plug from pins 1 and 2.
  • Place the jumper plug on pins 2 and 3 and wait approximately 5 seconds.
  • Replace the jumper plug on pins 1 and 2.
Each Dell Inspiron has a master password which will clear the BIOS password. You can get this number by calling Dell Technical Support at (800)624-9896.
Dell Technical Support will request the Service Tag and Express Service Code from the bottom of your Inspiron.

Thank You,
Your Support Tech.
