How do i bypass cmos battery - Computers & Internet

yes, but if you removed battery that is the same as the jumper.

try removing the cmos battery for about 10 minutes then replace
you can watch how to do it here Dell XPS M1330 ' CMOS Battery Replacement on youtube

You ca reset and remove the CMOS password by removing the CMOS battery inside your laptop, it is a 1inch in diameter battery that is 3v. this is a guarranted solution but you need first to open your laptop to remove this battery.

hi!
this is how to bypass CMOS SETUP password

*open the cover of you laptop,
*remove the cmos 3v baterry.
*remove the main battery
*push the power button for 10 sec.
*wait for 5 to 15 minutes
*put back the cmos battery and connect the main battery
turn on your computer and enter to cmos setup

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.

Disconnect the AC power.
Remove the battery.
Remove the CMOS battery.
Wait a few minutes.
Re-insert the CMOS battery.
Reconnect the battery.
Try it.

If all else fails, find your original bill-of-sale, to prove "ownership", and telephone IBM for support.

Hello,

the computer has been locked from the bios settings.

What you need to do now is to access the Cmos battery on the laptop, remove the Cmos battery and turn on the laptop without the Cmos battery.

The Cmos battery is where the laptop memorizes the password and stores it. So when the Cmos battery is absent, the computer cannot remember any password

The Cmos battery is like a watch battery, but its bigger than a watch battery. You can find the Cmos battery when you loose the laptop from under. But you must first remove the laptop battery before you loose the laptop. You can open the link below to see what a Cmos battery looks like:

Take care.

Before attempting to bypass the BIOS password on a computer, please take a minute to contact the hardware manufacturer support staff directly and ask for their recommended methods of bypassing the BIOS security. In the event the manufacturer cannot (or will not) help you, there are a number of methods that can be used to bypass or reset the BIOS password yourself.

Try this first : 
manufacturer name : Toshiba
password : Toshiba

Most Toshiba laptops and some desktop systems will bypass the BIOS password if the left shift key is held down during boot

Method 1 : Removing the CMOS Battery

The CMOS settings on most systems are buffered by a small battery that is attached to the motherboard. (It looks like a small watch battery). If you unplug the PC and remove the battery for 10-15 minutes, the CMOS may reset itself and the password should be blank. (Along with any other machine specific settings, so be sure you are familiar with manually reconfiguring the BIOS settings before you do this.) Some manufacturers backup the power to the CMOS chipset by using a capacitor, so if your first attempt fails, leave the battery out (with the system unplugged) for at least 24 hours. Some batteries are actually soldered onto the motherboard making this task more difficult. Unsoldering the battery incorrectly may damage your motherboard and other components, so please don't attempt this if you are inexperienced. Another option may be to remove the CMOS chip from the motherboard for a period of time.
Note: Removing the battery to reset the CMOS will not work for all PC's, and almost all of the newer laptops store their BIOS passwords in a manner which does not require continuous power, so removing the CMOS battery may not work at all.For eg:  IBM Thinkpad laptops lock the hard drive as well as the BIOS when the supervisor password is set.

Method 2 : Using the Motherboard "Clear CMOS" Jumper or Dipswitch settings

Many motherboards feature a set of jumpers or dipswitches that will clear the CMOS and wipe all of the custom settings including BIOS passwords. The locations of these jumpers / dipswitches will vary depending on the motherboard manufacturer and ideally you should always refer to the motherboard or computer manufacturers documentation. If the documentation is unavailable, the jumpers/dipswitches can sometimes be found along the edge of the motherboard, next to the CMOS battery, or near the processor. Some manufacturers may label the jumper / dipswitch CLEAR - CLEAR CMOS - CLR - CLRPWD - PASSWD - PASSWORD - PWD. On laptop computers, the dipswitches are usually found under the keyboard or within a compartment at the bottom of the laptop.
Please remember to unplug your PC and use a grounding strip before reaching into your PC and touching the motherboard. Once you locate and rest the jumper switches, turn the computer on and check if the password has been cleared. If it has, turn the computer off and return the jumpers or dipswitches to its original position.

Method 3 : 
Jumping the Solder Beads on the CMOS

It is also possible to reset the CMOS by connecting or "jumping" specific solder beads on the chipset. There are too many chipsets to do a breakdown of which points to jump on individual chipsets, and the location of these solder beads can vary by manufacturer, so please check your computer and motherboard documentation for details. This technique is not recommended for the inexperienced and should be only be used as a "last ditch" effort.

Method 4 : 
Password cracking software

The following software can be used to either crack or reset the BIOS on many chipsets. If your PC is locked with a BIOS administrator password that will not allow access to the floppy drive, these utilities may not work. Also, since these utilities do not come from the manufacturer, use them cautiously and at your own risk.
