The cmos battery is a watch battery on the mother board. Normally the size will be about 1/2 inch accross. Depending on the amount of room in the computer, you may have to removed the hard drive, DVD/CD rom drive, and other components to get to it.

P4P800 - VM BIOS Version 1012 to Upgrade 1018 Now CMOS can't save Date & Time


I'm sorry to have to say this but your CMOS battery connection is bad. There is basically nothing you can do other than replace the whole motherboard if it is too much of a problem.

One of my many computers is like this as well. I'm lucky in that as long as I leave that computer plugged in (it doesn't need to be turned on just plugged in), the CMOS won't reset its self. If you aren't that lucky then I would seek out a replacement motherboard.

If your cmos battery is new and the date and time not change. Try the following.
1. Clean the cmos battery terminals.
2. Check your mother board if there is bulges capacitor.
3. Check the memory you have using if in the same voltage requirements.
Hope this will help to you.

ASUS P5GZ-MX: Cmos Settings Wrong - Tryed New Cmos battery and setting time a date howto fix ?


It may just be that the new battery needs to be charged. I would leave it switched on for 24 hours to check. If this doesn't fix the problem, it could also be a failing BIOS chip or the charging circuit for the CMOS battery has failed. If the BIOS chip is not socketed or the cmos charging circuit has failed, you will need to replace the motherboard or find an electronics engineer to replace the failed components, this will probably be more expensive that a new board.

Password unloking


The simplest way to remove BIOS password is to simply remove the CMOS battery. A computer will remember its settings and keep the time even when it is turned off and unplugged because these parts are powered by small battery inside the computer called a CMOS battery. If we pull out this battery, the computer will forget alot of its hardware settings, including its BIOS password. This should not be performed on Laptops if you are not experienced working with laptop hardware.
If that doesn't work,you'll need a bios/cmos password recovery tool from http://www.biospasswordrecovery.com

Cmos battery error failure


The CMOS (BIOS) battery keeps the computer'a comfiguration and the Date & Time settings in the CMOS (BIOS) chip in its memory. When the CMOS (BIOS) battery is flat these configuration information is lost.
Replace the CMOS battery with a new one, in most cases this battery is a lithium 3 volt battery type CR2032 and it is coin size battery 18mm in dia.(check it to make sure the type of battery is installed on your motherboard).
When you replace this battery then go into the BIOS and set the Date & Time etc.

Does not boot up into Windows


This very well could be a motherboard problem. I would suggest removing the CMOS battery from the motherboard and looking for the "clear CMOS" jumpers which should be close to the battery. They generally are 3 pins, a jumper across 2 of them. Move the jumper to the other setting for about 30 seconds and then replace. (do this before removing the battery).
Then take the battery our for maybe 30 seconds and replace it. Try to start. If that doesn't work, I think you BIOS may be corrupt and you'll need to go the the ASUS site to get a new BIOS file.

Toshiba satelite bios password recovery


On laptops there isn't an easy way to recover passwords in the BIOS. Sometimes you can reset the password. Other times, you'll have to contact the manufacturer to get it reset.

Some laptops will allow you to reset the BIOS password by pulling the CMOS battery. The CMOS battery is typically located under one of the bottom panels for access to the memory or wireless cards. Some models have the CMOS battery connected by a small wire with a clip connector, others have the CMOS battery placed directly on the motherboard with a metal retainer clip.

Here is a link to a removable CMOS battery with wires: http://www.laptopparts101.com/wp-content/uploads/2008/12/removable-cmos-battery-560x420.jpg

Here is a link to a CMOS battery that is directly on the motherboard: http://www.laptopparts101.com/wp-content/uploads/2008/12/coin-cmos-battery-560x420.jpg

On a laptop, if you unplug the power cord, remove the laptop main battery and then remove the CMOS battery - and then wait at least 5 minutes, some models will blank out the BIOS password. Not every BIOS password can be erased by removing the CMOS battery - but if you are comfortable working on the laptop parts it is worth a try.

If removing the CMOS battery doesn't fix the BIOS password, the only option left is to contact the manufacturer for a reset. (If you took your laptop to a certified technician - they would just contact the manufacturer for the reset, and then bill the time to you!)

The number to contact Toshiba is 1-800-457-7777.

Bio password


Here is a complete guide to disassembly of the VGN-SZ laptop.
http://home.comcast.net/~nw_systems/vgnSZ.pdf
The trick here is to get to the CMOS/BIOS (referred in the manual as the 'reserve') battery. Remove this battery and leave the unit with no battery, A/C power or CMOS battery for an hour or so. Then replace the CMOS battery and reassemble. Power it up. Its going to 'yell' a lot since the BIOS was flushed and all information will have to be put back in. However after you do this, you should be all set.
Hope this helps!
