CMOS battery type for E machines T3642

Check CMOS and Memory Modules:::If the error message is "UNEXPECTED_KERNEL_MODE_TRAP," then it indicates you have problem with the memory of your computer. You need to check whether the SIMMs (Single Inline Memory Modules) are compatible and have the same speed. Secondly, also check whether you have set the CMOS (Complementary Metal Oxide Semiconductor) to the right amount of RAM. If these solutions do not work, you might have to replace memory in your computer....try to use system utility tool like Reginout.. Hope the problem is resolved.

Solutions to CMOS Checksum Bad Error

The CMOS Checksum Bad Error can be fixed easily by following the listed steps carefully.

CMOS Battery may not be functioning properly

If you suspect that your CMOS battery is not functioning properly, you can easily change it. Before changing your battery, reboot your computer to make sure that the error still exists. If it does, go into your CMOS and write down all of the settings. If all the settings are lost, you can usually retrieve them from your computer manufacturer. Now locate the battery and remove it, you might need to consult your computer's manual or technical support to remove your battery (the battery a flat, shiny silver colored and coin-shaped). Take down the CMOS battery's information such as volt, size, etc. Once you have your new battery, you can replace it and reenter your CMOS settings. If your battery was the cause of the CMOS Checksum Bad Error, you should have solved the problem.

Your BIOS may have been updated

If your BIOS have been updated recently, your CMOS settings may have reset. Make sure that the values entered in the BIOS are correct or simply reset them to the default settings. If you believe that a virus has updated your BIOS settings, run a virus scan and make sure that the BIOS settings are back to the default.

The Computer may not have been shut down properly

Sometimes when running MS Windows, if you shut down your computer without first properly shutting down your operating system, it will corrupt the CMOS settings causing the CMOS Checksum Bad Error. You can easily avoid this error by making sure that you completely shut down your computer properly before turning off the main power. Usually this entails going into the Start Menu, clicking on Turn Off Computer/ Shut Down. If improper shutdown was the cause of the error, you may have solved the issue.



akuma_ryu21 rate it pls!!

The CMOS checksum error occurs when the CMOS battery is worn out and the CMOS data gets corrupted. Replace the CMOS battery, this battery most likely a CR2032 lithium coin size button battery - check to make sure before you purchase.
After replacing with a new battery, then go to the BIOS configuration and set the Time & Date etc.

just replace the "CR2032 battery" in the motherboard... the enter the BIOS, then "LOAD SETUP DEFUALT"

Can you leave a better description of the problem?, are you getting 'cmos checksum error' msg when you startup? If so, this is normal after removing the CMOS battery and replacing, it should only display error msg after 1st start then no more...

Hi robynonis
Yes, definatly the cmos battery. Please make sure you replace with same type battery.
Regards Go-Tech

Try to reset your Bios by remove the CMOS battery
if it's just same
you can to replace your CMOS chip in your board with the same type ( you can get it from useless or junk 'same type' motherboard)

Are the CMOS batteries good?

hi

2 things, first, you simply need to replace the cmos coin cell battery or worst case scenario, your processor may already be on its way to failing.

If your CMOS batt is ok, then try flashing your BIOS
