Generally, a "CMOS error" will occur if one of the following has happened:
- The configuration of the computer has significantly changed. Simply entering the BIOS and saving should remove the error message.
- The backup battery has gone dead. You can check for this by seeing if the time is incorrect in the BIOS. You would need to purchase a replacement battery.
- A checksum error can occur if the BIOS has been updated, or if some external program has modified the CMOS settings. Again, simply entering the BIOS and saving should fix the message.

What is CMOS Failure in computer mean?
stop watching so much porn..
Where does the CMOS power come from when the computer is off?
The complementary metal–oxide–semiconductor (CMOS) power comes from the CMOS battery located on the motherboard. This battery powers the Basic Input Output System (BIOS) and stores the start-up config for the computer.
The basic data and instructions used to start the computer are called?
It's a mixture of things. BIOS, CMOS, Operating system.
Is the hardware system configuration stored in CMOS?
yes it is stored in CMOS
Do you need a cmos battery for your computer to boot?
Most new computers can automatically determine the correct settings needed for your hardware, and some even store configuration data in a non-volatile Flash chip. These computers effectively do not need a CMOS battery for anything except maintaining the correct time. Older computers, where you had to specify the parameters for the hard drive in the BIOS, need a CMOS battery. Otherwise, you would have to enter them in every time you booted the computer.
The computer says the cmos checksum is incorrect please reload cmos default value how do you fix this?
you need to reset your cmos http://www.wikihow.com/Reset-Your-BIOS http://www.youtube.com/watch?v=Pdp_L5IxaNI

What should you do if you get the POST error CMOS checksum bad?
cmos ram might be corrupt. run bios setup and reset bios to default settings. if it occurs again try, flashing bios.
When you restart your computer the error message cmos setting wrong and cmos cheksum bad comes up?
Chances are that the CMOS Battery on the motherboard is dead and needs to be replaced. Without this battery, the computer can not remember the CMOS settings when the power is turned off.
How do you reset CMOS when the computer shows CMOS error in setting?
Your motherboard a CMOS jumper, to find it you need to look through user's manual. Also in user's manual it's written what you need to do to clear CMOS memory.
Why does my computer go straight to the bios?
You likely mean that it is going directly to the CMOS Setup. Every computer with a BIOS boots using the BIOS, but if the BIOS detects problems with the CMOS data, it goes to the CMOS setup so the user can fix it. What the BIOS does is verify to see if the calculated checksum of the stored data matches the recorded checksum. If they don't match, the CMOS settings are dumped and changed to the defaults, and the user is either prompted or taken to the CMOS settings.While the CMOS can be scrambled at random or due to misbehaving software, the main cause would likely be a bad CMOS battery. It could also mean the CMOS chip is failing (since some contain an integrated battery) or that there are other hardware errors -- such as a stuck keyboard or a bad hard drive. It generally should tell you why you are being sent there. In a rare situation, someone may have the CMOS jumper in the wrong place, perhaps because they bought a motherboard themselves and received it that way.
CMOS checksum error Default loaded Warning CPU has been change Please re-enter CPU setting in the coms setup and remember to save before quit?
the main reason this happens is when the CMOS battery needs replacing.if the problem isn't resolved by doing this then I would flash the motherboard bios
Are Cmos in a modern computer?
Yes CMOS is available in modern computer. CMOS definition: Complementary metal-oxide semiconductor, or CMOS, typically refers to a battery-powered memory chip in your computer that stores startup information. Your computer's basic input/output system (BIOS) uses this information when starting your computer. CMOS-related error messages could be caused by a faulty or discharged battery. The battery can become discharged if your computer has been turned off for a very long time. To resolve CMOS-related errors, check the information that came with your computer or contact your computer manufacturer. Because your CMOS settings are specific to your computer's hardware, Microsoft can't provide specific instructions for changing them.
How can you easily clear CMOS including clearing the password?
how to clear computer motherboards cmos passwords
Which of the following is not a computer language basic snobol cmos forth?
CMOS
Is CMOS a computer language?
No
How can the CMOS be cleared on the computer?
There are three ways to clear the CMOS on a computer. You can access the BIOS menu and reset the BIOS settings, you can use the motherboard jumper or clear it by reseating the CMOS battery.
