SOURCE: Gateway 450rog cmos battery

The CMOS battery is located on the motherboard, just under the bottom left side of the keyboard, by the letter 'V". It looks like a clock battery, marked 3V (volts). The battery comes out of its "cage/connector" by gently lifting it with a small flat screwdriver. Replacement CMOS batteries are inexpensive and readily available at any computer shop. Hope that helps

SOURCE: want to replace cmos battery in Toshiba Satellite A10

On Toshiba laptops you hit the ESC key as soon as you turn it on & then you
are given the option to hit the F1 key to enter bios.


As to the cmos battery, they couldn't have hidden it better if it was the Queen's diamond!

It is near the bottom of the laptop on the right side, almost directly beneath the pause/break key.
Problem is, you have to disassemble the entire laptop to get at it!

Disassembly instructions for the Satellite A10 are here

SOURCE: HP PAVILION ZV6000 LAPTOP CMOS BATTERY LOCATION

You have to take the keyboard off. Gently pry the plastic strip that is between the top of the keyboard and hinges. Unscrew the (2 to 4) screws holding the keyboard down. Slide the keyboard up and out. You should see the battery with 2 wires going to the motherboard. Pull the battery connector off the board, take out the battery and wait for about 30 seconds. Replacing it is easy once you have it open.

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.

How to verify that the CMOS battery needs to replace


<p>The CMOS battery is named after the Complementary Metal Oxide Semiconductor power. The CMOS has the current date and time functions for desktop and laptop computers. It allows the computer to automatically adjust the time, even on computers that are disconnected for long time. When a computer no longer has the date and time and forget it on every boot, the CMOS battery probably needs replacing. Some computers have messages when the battery is weak, while others just lose the current date and time after each shutdown.<br /> <p>Time & Date Errors<span> </span><br /> <p><span> </span><br /> <p>1. Turn on the computer. Look in the task bar at the bottom right. Make sure the date and time is set correctly. Double-click the time and click the up or down arrow to switch to the correct time. Click on the arrow next to month to change the month. Click "OK" when finished.<br /> <p><br /> <p>2. Turn off the computer. Wait 3 to 5 minutes and start the machine.<br /> <p><br /> <p>3. Look on the taskbar to see if time was lost and said a strange date January 1, 2000. Replace the CMOS battery, if this is the case.<br /> <p><br /> <p>CMOS Error Message<br /> <p>1. Look for error messages like "CMOS checksum error", "CMOS Read Error" or "CMOS battery failure" when you start your computer. These errors are caused in the machines shut down for several months or when the CMOS must be replaced.<br /> <p><br /> <p>2. Let the computer on for 24 hours. Restart the computer and find the error.<br /> <p><br /> <p>3. Change the CMOS as the return error.<br />

How to reset forgotten bios password on a dell precision 220


If you know the current password just boot the machine and look for what key to press to get into the Bios or Setup. There you can change it if you know the current password.

If you don't know the password, then you will need to remove the CMOS battery from the motherboard and let it sit for a couple of hours. This will cause the computer to clear memory of everything. Then replace the CMOS battery and start the machine. Unfortunately you might have to disassemble the laptop to get to the CMOS battery.

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.

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!

Good Morning Sir... My Mother Board Is DG41 WV In This System Problm Is Cheq CMOS Problem... So Iam Change The CMOS Battery... Again Smae Problem Phase... & CLR Cmos Jumper Changed Again Same...


If you've replaced the CMOS battery, set the date and time as well.

If the CMOS setting default to the very first date (1st January 20??), it'll automatically report the "Check CMOS" error.

Let us know if this works,

Where is the location of the Cmos battery for my


You really need a service manual to try & locate the CMOS battery. With laptops the CMOS battery can be different on each model. These are often located on the motherboard below the keyboard, but a service manual should help you.
