Where is bios reset

The above applies mainly to desktop machines...were you inquiring about a laptop? It will have a clock battery as well, but the "yank the battery" trick won't work on mobile hardware. It is still possible to do, just might want an experienced hand to assist, as it involves cracking into the laptop. Most laptop pc's have two tiny metal contacts on the board, usually situated near the RAM expansion slot. A flathead (non magnetic, of course) screwdriver is is usually sufficient to bridge the gap between the two metal points, effictively "shorting" BIOS's connection to the power source. That will cause the BIOS to reset back to factory defaults, restoring default or "failsafe" settings. On many machines this is the only way to remove a startup or BIOS administrative password. PLEASE SEEK ASSISTANCE with this, as it is incredibly easy to seriously damage your hardware while trying to crack into the case. You can, if needed find disassembly instructions for your make/model on the OEM manufacturer's support page... which should help if you absolutely have to do this yourself.
Good luck!

Reset cmos, doesn't switch on

Plug out your pc, hold the power button for a few seconds and then take out the battery. Then wait a few minutes and put the battery back in. This should reset your cmos. If this doesn't help then the problem might be a corrupt bios, defective psu, faulty cpu or memory.

Replace cmos battery and case openning

Asus motherboards usually use a lithium CR2032 battery for CMOS. Also, on the top of the old CMOS battery you took out there should be the exact battery type engraved on the surface.

Batteries Plus in Wichita, KS has a good online store for purchasing your replacement battery.

My hp desktop L1506 is locked and I forgot my password... Can I fix this

When you boot up to the log in screen type in administrator as user to log in if you cant log in

during the boot up process you will see on the screen for a short amount of time press a certain key to enter set up press and hold that key during the boot up process to enter BIOS using the arrow keys scroll down to set user password or supervisor password you can change or remove your password from there

The most common way that we know on how to reset or clear the BIOS password is to physically remove the power from the computer by disconnecting the power plug and then removing the Cmos battery for 30 minutes from the motherboard.

Another way is to reset the clear CMOS jumper on the motherboard itself.

Both of the 2 methods mentioned works because most motherboards use a battery to sustain the BIOS/CMOS settings for the motherboards PROM chip. So by cutting off cmos the battery power, the BIOS/CMOS settings will be erased.

cmos battery Under the keyboard or bottom of laptop - If you are working on a laptop computer the location of the dipswitch (almost never a jumper) can be under the keyboard or on the bottom of the laptop in a compartment such as the memory compartment. Although on some motherboards the Cmos battery is soldered in

Often many users will leave the administrator account alone or have other accounts with administrator rights. If you're not logging into the computer as administrator or have other accounts follow the below steps to reset your other accounts password.

Reboot the computer into Safe Mode
During the boot process tap the f8 button three times this will boot into safe mode where the only things working will be your mouse and keyboard enabling you to attempt to repair your computer Advanced Boot Options screen appears.

Select the Safe Mode option using the up and down arrow keys, then press the ENTER key. Choose "Windows XP Home/Professional", depending on the version of the operating system.

Press ENTER. Shortly, the welcome screen should show.
Log in as "Administrator". Click Yes to not use System Restore Mode.

Click the Start button. Choose Run and type in "control user passwords" (without the quotes). Click OK.

Select the "Administrator" user. Click Change my password. Enter a new password in the corresponding text boxes. Click OK. Write this password down and store it in a secure place Close the User Accounts window and restart Windows.

In User Accounts select the account you wish to change the password for, click change password and then enter the new password or click remove the password to remove the password from the account.

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

Many RTC's require an external battery. If your RTC is one of this type you can clear the BIOS password just by unsocketing the RTC and reseating it

Hope it helps

Hello, Is it possible to reset the BIOS without removing the battery? The battery is on the other side of the motherboard.

If you have attempted to change something in your BIOS so you cannot alter or change any settings because the computer won't boot up properly, unless you have a CMOS reset button on your motherboard the only other way if you can't get into BIOS is to remove the CMOS battery, the CMOS battery is never on the otherside of the motherboard because all the connectors are always on one side of a motherboard

the CMOS battery is a silver flat battery, much like a thing watch battery, remove this battery for 15 seconds so there is no residual power left in the motherboard and then reinsert and reboot your computer

if you can get into BIOS there should be a restore to factory defaults settings in there somewhere.

Machine POSTs and boots only after a CMOS reset and a reset of the Date/Time entering and exiting the BIOS. From here on in, it will boot and reboot, unless the power is turned off. Then it must be powered...

It seems as though your BIOS settings are saving correctly, most likely due to a bad CMOS battery. You should replace the battery, you can normally find them near the watch batteries in stores.

My PC connects but does not generate image .. I guess I have to reset the CMOS! The problem is this?!

It sounds like you have a motherboard issue. You can try connecting another video card and see if that helps. If you do decide to reset the CMOS, there is a jumper that you can unplug that is near the CMOS battery. If you disconnect that jumper and then boot, that will reset the BIOS. Failing all that, you will have to replace your motherboard.
