Reset cmos program

There are of course other situations, but the above are by far the most common reasons to make a CMOS reset. What is CMOS? What can i do? I assume no liability for the accuracy, completeness or topicality of the following instructions. It may be completely different for your computer! The duration for a complete loss of data could differs between some seconds, hours, or several days. Notebooks don't have any jumper. They have an additional small, hidden IC which stores the password.

That means: the password is not stored inside the CMOS! But you can also try to reset the CMOS. Other notebooks are able to store the password on a hidden hard disk sector. Your only chance is to contact the support of your notebook manufacturer. Depending on the manufacturer, you have to send him the serial number of the notebook and you'll get in many cases free of charge an individual master password to unlock the notebook. Some other manufacturers even offer only the replacement of the notebook's mainboard - which will be really expensive!

Most mainboard manufacturers have a download section on their websites where you can find the manual of your specific mainboard type. Inside the manual there should be a layout drawing which shows the jumper position.

Read the manual to find out how you can reset the CMOS! Because the procedure can be very different! For instance, most mainboards have to be completely dead, but there are others where you have to reset the CMOS when power is on. Soldered points : Sometimes there is no connector strip and you'll only find 2 soldered points which must be bridged e.

If you don't like to wait, you can try the following instructions, but as I said at your own risk. Hi Great resource, thank you. I have bought lenovo x with bios settings supervisor password protected. Not too good with electronics, so will probably not go beyond the battery and 10 cent trick.

Quick question I haven't found addressed. If I just accept the inability to use Bluetooth or change the booting order, what will happen when the CMOS battery eventually dies and I replace it? Would you expect any problems making the laptop unable to start? The bios clock is now set to , but this is not causing any problems to windows 7. Thank you. Similar boot prob, but with no video. Did procedure above: now power on button press does nothing.

What now? Hello: Still not working. When I switch on the PC, it tries to boot, then turns itself off for a few seconds, then turns itself on again and boots to the screen asking me for a password. This PC was working fine, I went into the setup a few days ago to check the user and admin passwords, but noticed the one was what it should be, but the other, which should have been the same word, just would not accept, giving wrong password error for the old password to be typed in etc.

I thought that was strange as both PW's should be the same word etc. I guess the CMOS chip must be faulty, which is why it won't reset??. Thanks TomW. TomW Try this Please note: while testing, you should remove all unnecessary additional hardware components from your PC not on Laptops!

No USB-Sticks! No TV-, Sound-, and other Controller cards, etc.! Don't use USB3. If all this do not work, then the motherboard or bios chip itself could be defective or some other connected hardware components prevents the PC to boot up. Everything has been working fine. I have also removed all hard drives etc. Close Window. Caution Use of unsupported motherboards can result in improper operation, damage to the desktop board or processor, or reduced product life.
