Will removing the CMOS battery clear the BIOS

I am trying to clear a blue screen error. One of the steps listed says to disable the BIOS cache and shadow memory. But there no options in the BIOS that will alow me to do this. By disabling the quite boot I am able to confirm that both the cache and shadow memory are enabled in the BIOS. I want if the idea of removing the CMOS or RTC battery will clear the BIOS cache and shadow memory?

Sony vaio blue screen

Windows XP can cause blue screens on many occasions. Like ram failure, CMOS setting issues, OS problems or by any other Hard ware issues.
1. Make sure the bios settings are ok. It is always recommended if you can run your system with the default settings. To do this clear the CMOS by removing the battery and keep for around 1 minute. and put it back. (While this the power should be removed.) Now try and see if the problem is still go to step 2
2. Remove the RAM & Display cards and clean the contacts with a non dust eraser (dont use erasers with sand, old erasers as this might lead to worse problems.) Now try and see if the problem is still go to step 3.
3. Remove other cards and with out those cards check the problem is still there. Go to step 4 if the problem is still there. If its not there Clean the removed cards contacts with a eraser and fix the cards one by one and check.
4. Try installing OS.

If the problem is still it may be your hard disk, Motherboard or the processor. Better to check with a technician.

Hope this helps.

Bios errors code fff

Not knowing your computer make and model makes it difficult to give you step by step directions, but the first thing you should try is to reset the bios to factory settings. You can do this by entering into the BIOS menu and look for something that says things like

reset to default, factory default, clear BIOS, load setup defaults

Doing this will clear your CMOS which may be all that you need to do.

Another issue with this error could be that the CMOS battery is bad. This battery is similar to a watch battery. Depending on your computer, you can open it and replace this battery.

If this does not clear up this issue, please repost the problem with some more specifics on the type of computer you have and any additional information on your screen. It will be helpful to resolve.

I have an acer laptop 5735-4061. I was using this morning just fine. I got up to go do something and then I came back and there was a black screen with a blue bar in the middle of the screen. I says...


If you have forgot BIOS password then you have to reset CMOS jumper setting. Please follow the below steps: Open the Laptop back panel. Locate the CMOS battrey, remove it & then with the help of a screw driver keep on pressing the terminal inside it and turn ON the computer for 10 secs and Turn Off (make sure you keep on pressing the terminal with a screwdriver while turning ON). It will clear the BIOS setting. Now, fix the CMOS battrey & restart the computer. This will take care of the issue.

Thanks and regards,

Steps for Clearing BIOS Password Check

If users set BIOS Password (Supervisor Password and/or User Password) for a security reason, BIOS will ask
the password during systems POST or when systems enter to BIOS Setup menu. However, once it is
necessary to bypass the password check, users need to short the HW Gap to clear the password by the
following steps:
• Power Off a system, and remove HDD, AC and Battery from the machine.
• Open the back cover of the machine, and find out the HW Gap on M/B as picture.
• Use an electric conductivity tool to short the two points of the HW Gap.
• Plug in AC, keep the short condition on the HW Gap, and press Power Button to power on the
system till BIOS POST finish. Then remove the tool from the HW Gap.
• Restart system. Press F2 key to enter BIOS Setup menu.
• If there is no Password request, BIOS Password is cleared. Otherwise, please follow the steps and
try again.
NOTE: The steps are only for clearing BIOS Password (Supervisor Password and User Password).

Checksum Error after Bios Upgrade K7VZA

Have you tried resetting the CMOS? Often, after upgrading BIOS you need to clear the CMOS and re-setup to handle the new features. You should have a jumper to clear CMOS, or you can remove the power from the system and remove the battery for a few seconds to clear it.

Let me know if this clears up your issue.

HP530 bios resetting

The only way to clear the password in BIOS is to open the cover and take out the battery on the motherboard. It is not hard to find on the motherboard, it looks like a watch battery. Take it out, wait about 5 mintues. then put it back in and boot. That will clear the BIOS password.
