Removing the CMOS battery for about a minute and putting it back in might help restore BIOS to default settings. I have not done this on a laptop yet, but that is generally how you reset BIOS. You may have to find which 'compartment' on the underside of the laptop to unscrew to remove and reseat the CMOS battery.

ASUS A3H notebook: how do I reset the bios password. First, I press F2, then I'm able to get through the bios, then I changed the password ( I didn't place any or no password at all, just pressed...

Well..... It thinks there is a password. Have you tried just pressing the enter key? If so, then you have to reset the CMOS. To do this you will need to disassemble to get to the CMOS battery. I could have a jumper but the easiest method is just to pull the CMOS battery. On older laptops it is a rechargeable battery (nicad or lithum) and on newer ones they use a coin cell battery like desktop computers.

Best of luck, Jim

How much is asus ee pc cmos bios battery?

You need to be more specific about the model, but cmos batteries are generally 3V buuton cell type. Some are fitted into sockets on the motherboard, but most laptops have one covered in heat-shrink plastic and with a flying lead to connect to the motherboard. To get a proper ASUS battery specific to your laptop will probably cost between £15 & £30 pounds but if you are technically minded you could buy a 2032 button cell for no more than £5 and replace the battery inside the heat-shrink plastic. I would check the voltage of the existing cmos battery first though because it may not be faulty. If the voltage is less than 2V then it will not work properly but if the voltage is above 2.5V then it is not faulty and does not require replacing. Between 2V & 2.5V is a bit of a grey area but may cause intermittent problems depending on the laptop. These batteries are designed to last at least 5 to 6 years (usually the life of the laptop) because under normal use the cmos will be maintained by the main power source (the laptop battery). I have never changed the cmos battery in my desktop PC or in my laptop, both of which are over 5 years old.

How to unlock a acer password laptop

If you cannot access the machine after if has been powered up, it is still possible to get past the BIOS password. The BIOS password is stored in CMOS memory that is maintained while the PC is powered off by a small battery, which is attached to the motherboard. If you remove this battery, all CMOS information (including the BIOS password) will be lost. You will need to re-enter the correct CMOS setup information to use the machine. The machines owner or user will most likely be alarmed when it is discovered that the BIOS password has been deleted.

Its simple. there is a small cell battery in all motherboards. its usually for BIOS CMOS memory. if the battery drains up the memory in bios just erases. Date and time, bios CMOS settings will be reset after every shutdown or restart. try to replace that battery. Battery is used CR2032 coin cell.

Cmos settings error system hait,

You will need access to another computer and go to:, choose you country, then "Download", the on the next page, "Download" again. Select you "Product, Series and Model". Motherboard, Socket 478, P4P800-SE click "Search". Then choose you operating system. You will get to the page where you can download the latest BIOS, and install program. Read how to upgrade your BIOS and follow the directions carefully.

I suggest you also change the CMOS battery before you upgrade to make sure a dead battery is not the cause for the CMOS corruption.
