    I put a new Intel Pentium 4 processor in my VGC-RB30 Sony vaio and when I went to start the computer again there is no picture on the monitor, and it does not boot. I read yesterday that it maybe a capacitor,but how can tell which one it is if that is it? I have tried to reset the bios,by taking out the cmos battery and little clips also but it didn't work. Does anyone have any idea's?? Thank you Debra

    Maybe I didn't explain myself, when I push the on button the fans run, but there is no boot and no picture on the monitor. So hitting f2 won't work...

    Be aware of the antistatic rules before opening up your computer make sure its turned off and unplugged at the wall Test all power and data leads that attach to your hard drive IDE,SATA the leads from your (motherboard to your hard drive) make sure they have secure dust free connections and are not faulty if its a 40 pin flat ribbon type it will be the first to fail make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even something as small as a faulty electrical fan and its lead can cause you problems computers need all power and data to continue through every working device and to have an end so any faulty leads will end up with a computer error Make sure your graphics card is securely seated with no dust built up or in the socket if you remove your graphics check the socket to make sure its dust free Restart your computer then reinstall it this should activate found new hardware wizard Check the vga lead for secure dust free connection or try another vga lead.

    Ok, I the tower hasn't had power since Tuesday. So after reading your suggestion just now 9:33 a.m. Thurs I removed the CMOS battery, and CMOS and BIOS jumpers. I have already done this,but after reading your suggesOk, I am going to unplug everything in the tower,and take the CMOS battery oution I thought maybe if I took them out and left them out for longer then 10 or 15 min it would make a difference. I read somewhere in my search for this that sometimes an hr is required. If this doesn't do it I will try another monitor before I start buying more parts. Thanks Deb

    yes some times you will need to remove it a bit longer yes if you can try another monitor would narrow the problem down have you checked the vga lead ?

Restart your Sony Vaio computer. Press the "F2" key to enter the BIOS. Use the arrow keys to highlight the "Load BIOS Defaults" menu option. Select it by pressing "Enter." Highlight "Load BIOS Defaults" again and hit "Enter." This will reset all of the settings of your Vaio's BIOS back to their original factory defaults. You can now select "Save Changes and Exit" to exit the BIOS.

WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. http://www.kitchentablecomputers.com/static.php - rules
Only work inside the computer case when the power has been switched off and disconnected. Never open the power source. Power down the system and disconnect the power cord. Wear an anti-static wrist strap to avoid electrostatic discharge damage to the Asus motherboard or CMOS chip or other sensitive components. Remove the cover and locate the CMOS coin cell battery and remove it from the system by gently pushing on the retaining clip and popping the battery out although on some motherboards cmos batteries are soldered in Discharge the CMOS chip by leaving the battery out of the system for up to an hour, depending upon the particular chip and motherboard combination. Replace the battery and replace the cover on the system. Connect the power cord and boot the computer. Save changes if prompted by the BIOS for system memory, drives detected, and other settings, and set the date and time if prompted at this time, or alternately set the date and time when the operating system finishes loading.
If your computer does not have a CMOS battery or you're unable to find it you'll need to do a hard reset on the CMOS using a jumper or dip switch on the motherboard. Information on finding these can be found through your computer or motherboard documentation. or you might set failsafe or optimised defaults Restart your computer During the boot process you will see on the screen to press a certain key to enter setup usually the Delete or F2 key this will vary depending on your computer and operating system Press and hold that key during the boot up process to enter BIOS using the arrow keys load failsafe defaults or load optimized defaults press escape then press f10 to save to cmos to restart hope this helps

How can i reset the cmos in my ms200 all in one computer?? it shows that my hasrd drive is not working, and it is really working in other computer


Hi,

To reset the CMOS the easiest way is, remove the motherboard battery for ten minute then install it again. It will clear the CMOS. Then reset the CMOS/BIOS setup, date/ time etc. Another way to clear CMOS is, reset the CMOS Jumper in motherboard.

To detect your hard drive you can try to check by change the hard drive cables. Change the port in motherboard. Check the BIOS setup and reset it if need.

I need to reset the CMOS Password for my acer extisia 4230


for that you need to open back cover of laptop .
Then find motherbord there.
Pull CMOS cell from motherbord for 10 minutes then refix it .
Also you can clear cmos with jumper find jumper near cmos cell named "clear CMOS " it has 3 pin
Set jumper i 2-3 position then power up 1 time then again set jumper in 1-2 position then it not ask for password.
Let me know if you need more assistance.
Thanks.

BIOS reset


By resetting the CMOS battery all you need to do is to teardown your laptop and have to remove and reinstall the CMOS battery. And for the replacement of the CMOS battery of your Samsung laptop just call SAmsung technical support so that they can give you the exact model of the CMOS battery and where you can have the battery. Thank you.

Reset bios password


You need to locate the Cmos battery, not the jumpers, this is not a desktop.

Locate the Cmos battery, disconnect the battery for ten seconds, and Bios will reset to factory default.
