Question about Gateway NV55C03u Laptop

1 Answer

I removed the CMOS battery out of my NV55CO3u gateway laptop and it still didnt remove the Unlock password that I forgot.

Removed power cord, and battery and took BIOS battery out and let it stay like that overnight for at least 8 hours and still the HDD is locked. Ordered system disc & recovery discs 1 thru 3 and tried to restore back to factory settings but still failed.

Take the battery out of the laptop and then hold the power button on the laptop for 2 minutes.

This should reset the BOIS and erase the unlock password.

SOURCE: Lost Bios Password for Gateway Solo 1450. I have

From my experience there is no way to retrieve or remove a unknown hard drive (HDD) password. The bios passwords and windows passwords are no problem to remove, but the HDD password cannot be removed. Only option I know is to replace the hard drive. I have done this on about a dozen PC's

There are - luckily - two tiny software that will help you to RESET the CMOS password.
The first one is called CMOSPWD and you can get it from HERE.
The second one is called KILLCMOS and you can get it from HERE.


Good luck!

So who put the password on it? 99% of the time if there is a Hard Drive Password and the person in possession of the laptop don't know the password, the laptop is stolen. The original owner put the password lock on the hard drive to keep thieves from getting to sensitive data. The owner could have set the password remotely once the laptop was stolen. Your system is toast. The only remedy is to get the original owner to remove the password.

Password hack


While removing the onboard battery and disconnecting all power for 5 minutes may clear the bios, some passwords are written into NvRam (non volitile Ram). This may require you to move some jumpers. Try this.
It may be necessary, on occasion, to clear the CMOS settings. When the CMOS is cleared, all information stored in the CMOS is replaced by default data, which means that all of the configuration information, such as hard drive types and I/O port setup, is cleared, including the password. Use the following procedure to clear CMOS:
  1. Power down the computer.
  2. Remove the left cover of the computer.
  3. Wearing an anti-static wristband grounded to the chassis, remove the jumper from pins 1 - 2 of the Clear CMOS jumper block (JP15) and install it on pins 2 - 3.
  4. Remove the jumper from pins 2 - 3 of the Clear CMOS jumper block (JP15) and install it on pins 1 - 2. (NOTE: Some earlier systems will power up as soon as the jumper is removed from pins 1-2. Later versions of the BIOS change this, 6.00.10 or later.)
  5. Reinstall the cover and power up the computer.
  6. Run the BIOS Setup program to reconfigure the system.

I forgot my sony vaio bios password


Remove the battery, remove the power cord and start taking the laptop apart. You will need to remove the CMOS battery located on the motherboard and let it sit for an hour or two. Then but it all back together. The CMOS battery is a silver battery about the size of a nickel.

My Acer aspire 4520 windows vista laptop is locked. can someone helph me? to change my user name and password. I forgot my password.


Hi there, this may work, try this.

Take off laptop battery, remove power cord, turn laptop upside down.
Just take off screws on the covers you see, which let you see HDD, Memory,Wireless card,.... ,
take off the cover or check on line for service manual for your specific model on how to remove the plastic cover/ covers, which is covering the CMOS battery which is some time wrapped up with yellow tape. Just remove the battery by holding on the white connector which attached to the motherboard with black and red wires. Gently pull from the motherboard.

Now without the CMOS battery, connect power cord and turn on the laptop, it should turn on. Now turn off , remove the power cord, check voltage on battery , it should measure very close to 3volt (2.5 to 3.0 volt), otherwise get a new one, connect the battery, put back covers, and now you set a new password.

I have the 7 in ch sylvania notebook and i forgot my password. How can I reset it?


Remove the CMOS Battery

Detach the CMOS battery from the metal holder. Some Gateway CMOS battery holders have tabs on both sides, while with others you can lift the battery out. Press down on the tabs and the battery will pop out. Wait two minutes, then push the battery back in. This will change the CMOS settings back to default and reset the Gateway BIOS password. Replace the panel and cords. Turn on the PC and enter the BIOS menu by pressing F2 repeatedly to create a new password. To bypass creating a BIOS password, boot to Windows normally.

Then everything will be just fine.

Thanks.

I forgot my gateway model ML6230 bios password, i need a new password for it (reset the password).


A method you can try if you don't have a password reset software is by removing the CMOS battery. Remove the CMOS battery then turn the computer on. The system BIOS will be reset and password will be removed. Then you can put the battery back in. Click on this link for the Gateway ML6230 Notebook PC Manual. Check page 36 for CMOS battery removal instructions.

Forgot my power on password


Remove the battery and to the power cord.
Remove the two screws that secure the keyboard. After removing the keyboard, remove the battery “RTC” to stop providing energy to epprom BIOS. After the upgrade or downgrade, or any repair, leave the Laptop for 5 minutes, without any source of energy.
Then connect only the power cord without battery and without the battery “RTC” of the Bios.
then turn on the pc without the battery and press f10 change the admin password put the battery of the laptop again not the rtc battery then save changes and exit, reeboot with the win xp disk inside , change boot order and done i garantied it work install xp and then connect the rtc battery done. jajaja easy

Dell latitude d620 power on password can't remove


No need to short out any pins, shorting out pins allow you to reset the BIOS quickly. When you leave the BIOS/CMOS battery out overnight, this will reset the BIOS (you only need to leave the battery out for 1/2 + hour to do the same thing).
