You should have a strip above the keyboard that needs to come off gently pry it up and off then you will see yhe screws that hold on the keyboard and the cdrom if you remove them and lift off the keyboard the rest of the motherboard will be exposed for removal

I want to that how i reset my recovery password and where the actual location of CMOS Battery?


In computing, BIOS (basic input output settings) refers to the information stored regarding a computer's hardware configuration, the system date and time and any applied password. This information is known as the BIOS or CMOS settings--the BIOS is stored on a small battery-powered semiconductor chip known as the CMOS (complementary metal oxide semiconductor). Having a CMOS or BIOS password restricts unauthorized changes to the system's hardware configuration and, in some computers, may even be required for booting. A lost password may be reset by removing the CMOS battery, clearing the motherboard jumper or using a software-based password cracker.

Removing CMOS Battery
1. Shut down the laptop and unplug its power cord from the wall outlet. Remove the battery cover under the laptop and gently raise the battery from its dock. Unplug any peripheral devices with a live power source connected to the laptop, such as a modem or printer.

2. Locate and remove the CMOS battery. Refer to your user manual or visit the manufacturer's website for your laptop's architecture. Follow manufacturer recommended procedure to access and remove the CMOS battery. Depending on make and model, this procedure may be more involved for some laptops and not others. The CMOS battery is a flat circular shape and resembles a watch battery.

3. Wait 30 minutes and then put the battery back in. This will erase all information stored in BIOS. Assemble the laptop, making sure you leave no loose connections. Power up the laptop and press "F1" when you get the "CMOS cheksum error" message. Type in a new password.

Clearing CMOS Jumper
1.Turn off the laptop and access the motherboard following recommended procedures.
2.Locate the jumper in the motherboard. If you do not have your motherboard documentation, locate a single jumper near the CMOS battery. In some laptops, the jumper may also be labeled in the motherboard. Put the jumper setting to "Clear" and reassemble the laptop.
3.Turn on the computer and hit "F1" when the "CMOS checksum error" message is displayed. Navigate through the BIOS settings interface to load default settings and apply a new password.

Using Password Remover
1.Download a software-based BIOS password cracker. There are numerous free programs able to recover or delete CMOS or BIOS passwords from virtually all motherboard brands. Download the file from a trusted source and save it to the desktop.
2.Burn the installed file to a CD using image burner software. Insert the CD and access the password remover tool.
3.Note the password or use the program to set a new password.

I hope you find it very helpful. Thank you for using fixya.

Resetting BIOS password


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 usually looks like a couple of coin batteries wrapped in plastic and connected to motherboard by a two wires connector.

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

Several Dell Laptop 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:

ALFAROME
BIOSTAR
biostar
biosstar
CMOS
cmos
LKWPETER

I need to rest password in bios


Hi,
Removing the RTC battery and leaving it uninstalled for 5 or more minutes causes all passwords and CMOS settings to be cleared. BIOS password can be removed by temporarily disconnecting/ removing the RTC/ CMOS (Coin-cell) battery from the motherboard.
Disconnect the coin-cell battery from the system board and it will reset the BIOS to its default setting and the password would be gone.
Please Refer to Page 29, 106 & 79 of the REPAIR MANUAL IBM T40 for Battery removal, keyboard removal and RTC battery removal instructions.
The Backup Battery (RTC, CMOS) is located under the keyboard. So you have to remove the keyboard to access the battery. The above Manual from IBM shows the exact method/ instructions and pictures for laptop dis-assembly for the purpose.
If you are comfortable with working inside such electronics, you can't do it yourself, or else you may seek help from local laptop service professional.


Hope it helps! Good Luck! Thanks for using Fixya!

My emachine notebook is need to reformat but the bios has a password and i forgot it. i need to clear the cmos but mi cant find the internal battery.what the best solution in this problem? please help


To reset the BIOS password read the information from this link http://www.fixya.com/support/r7229632-reset_or_remove_bios_password

In case of your laptop I would suggest using software from Hiren's Boot CD to clear the BIOS (there's Kill CMOS on there that wipes the BIOS).

My laptop, emachine m5312 shuts down by itself despite the power settings to stay on, any ideas?


it may be set to hibernate in the bios. if it's randomly shutting down while you are working then you probably have an overheat issue.

Remove bios password


There are lots of tools/software available to reset bios password. Just google for "reset bios password" and you will find one of them, else just open your back side of your notebook. Open the screws and remove the bios battery (a circular shaped sitll battery). If possible change the battery with a new one or keep that battery out of laptop for some time. Now start notebook without the battery and shut down.Then reinsert the battery to laptop and start again. The password should be resetted by this process.
