Cmos Checksum Error Defaults Loaded Keyboard Unresponsive
a question USESFRITBR September 2016 When a CMOS Checksum error occurs during system startup, it could mean that the system has been cmos checksum error defaults loaded diskette drive 0 seek failure restored to default factory settings. The CMOS contains data related to BIOS and may have been reinitialized. It may also be possible to fix the problem by reinitialising BIOS. The problem could also occur due to

the depletion of the CMOS battery. If the user cannot locate the pin battery, the help of a computer technician should be taken to prevent damage to the hardware or motherboard. The CMOS checksum error - defaults loaded should be solved after changing the CMOS battery. Symptoms Solutions: Symptoms When starting your PC, the following error message is displayed: CMOS wrong CMOS MEMORY size WRONG CMOS Checksum Bad CMOS checksum error defaults cmos checksum error on boot loaded Warning! CPU has been changed please re-enter cpu settings in the cmos setup and remember to save before quit! You are prompted to: Press F1 to resume Press F2 to load default values and continue This is due to the fact that the CMOS, which contains data related to the BIOS, has been reinitialized and that your PC has been reset to factory settings. Solutions: Reinitializing the BIOS Before making any costly maintenance try: reinitialized the BIOS. Change BIOS battery If the problem persists this may be due to the fact that the battery powering the CMOS (when the computer is shut down it allows the CMOS to store information), is depleted. The CMOS battery is a small pin found on the motherboard; you can refer to the manual provided with your motherboard to change it or have the nearby computer technician change it for you if you don't want to risk any damage.

I regularly have the folllowing line appear when my bios starts up - CMOS checksum error - defaults loaded. It seemed to start happening when i downloaded spybot search&destroy. I have cmos checksum since removed the program but still have the problem. I have changed the cmos battery on the mobo as recommended in other threads, but it still regularly (every few start ups) happens. Any advice to solve the problem? The board is only six months old. CPU and RAM test fine. I have two hard drives, non raid, sata connection. Nov 25, 2005 #1 netbus TS Rookie when i started reading ya post.. i thought at the cmos battery too. cmos checksum error the message from cmos happens because the cmos has been reseted. this ussualy is done or by removing the battery temporarily... or by a jumper on the board. you replaced the battery so this isn`t a problem anymore. maybe the battery isn't fit correctly. or the jumper is not correctly set.. and periodically the contacts are touched. you should check both . it this fails.. is a motherboard problem... the cmos information is lost due to power lost from the battery that powers it. Nov 25, 2005 #2 nig TS Rookie Topic Starter Thanks for that I will look at the jumper and let you know..... Nov 26, 2005 #3 nig TS Rookie Topic Starter Ok checked CLR_CMOS (Clear CMOS) header and it looks fine - nothing touching the two wires, its open. Its a GA-K8NXP-Sli board and there is no jumper as standard. I checked the battery and changed it again. The problem persists - the CMOS checksum error came up again and the defalts were loaded. Nov 28, 2005 #4 iss TechSpot Chancellor Posts: 1,994 it is possible there is some sort of corruption in the bios. have you checked for bios upgrades for your board? Nov 28, 2005 #5 nig TS Rookie Topic Starter Ok....Have used the gigabyte @bios utility to update the bios. Will let you know how it goes..... Nov 28, 2005 #6 gemmi_2481 TS Rookie cmos b

The black screen appears when I boot up and reads: 'System BIOS shadowed. Check time and date settings. System CMOS checksum bad--default configuration used.'" Robert says he's tried contacting both Phoenix Technologies (makers of the BIOS) and Emachines, and neither company could help. (The BIOS dates back to 2003, and the system itself is long out of warranty.) Fortunately, this sounds like a pretty easy problem to fix. I don't think the driver-update utility is to blame here, but rather a poorly timed CMOS-battery failure. See, most desktop motherboards have a small battery that supplies power to the BIOS even when the machine is turned off. This battery might last two years or it might last 10, but when it fails, you'll often see an error message like the one above. (Your system will also fail to keep proper time, as the clock is one of the elements powered by that battery.) Most CMOS batteries are standard CR2032 "button" cells, which cost no more than a few bucks at your local drugstore, but check your motherboard documentation just to be safe. Replacing one is
