What is the meaning of cmos in cmos battery?
Complementary Metal-Oxide Semiconductor. The CMOS is where the basic modifiable settings of the computer (BIOS, Basic Input-Output System) (Date, time, memory) are stored. These settings are maintained when the power is turned off by a minute current, and that current is supplied by the CMOS battery

Complementary Metal Oxide Semiconductor. In computing the term CMOS is often used to mean the non-volatile memory that stores motherboard BIOS information. This was called the CMOS RAM or just the CMOS because it usually used a low-power CMOS memory chip, powered by a small battery. The term remains… common as nearly all modern computer components except the "CMOS memory" are constructed in CMOS technology. For the "CMOS", in modern computers, flash memory is usually used.. CMOS, short for Complementary Metal Oxide Semiconductor Is an MOS technology in which both P-channel and N-channel devices are fabricated on the same die CMOS is a widely used type of semiconductor. CMOS semiconductors use both NMOS (negative polarity) and PMOS (positive polarity) circuits. Since only one of the circuit types is on at any given time, CMOS chips require less power than chips using just one type of transistor. This makes them particularly attractive for use in battery-powered devices, such portable computers. Personal computers also contain a small amount of battery-powered CMOS memory to hold the date, time, and system setup parameters.. CMOS topology is very attractive also because circuitry logic synthesis is made automatically. So, you derive logical equation of digital circuit and don't bother about optimization and topology (not too much, maybe you have to edit place&route results). It is also a good idea to adopt CMOS topology because there will never be an high impedance node (each node will be connected to Vdd or GND), so you gain robustness and noise margin (distance between voltage of logical signals, here Vdd-0=Vdd) is always maximum. C OMS ARE attractive in some application because of the hi rejection signal to noise levels that is because they can operate at higher voltages then TTL however there are drawbacks the hi impedance of these devices if not accounted for can and will cause malfunctions.

CMOS stands for Complementary Metal-Oxide semiconductor. It is the computer chip that your BIOS is stored on. BIOS is information about your computer configuration. For instance, BIOS tells your computer to boot to your floppy drive first, before your hard drive. And you may change that sequence if …you like by changing the BIOS. When you start your computer it goes thru BIOS at startup to make sure all of your components are working. If you would like to see your BIOS, you would hit one of the F keys when your system starts up. Unfortunately there is no standard, as different motherboard makers use different F keys. But the most common is F2 so give it a try.. ( Full Answer )
You'll loose your BIOS settings and the computer won't be able to recognize some of the settings. If the battery goes dead, replace the battery, enter the BIOS settings and load the default, then do whatever is necessary under YOUR BIOS to recognize your hardware, then save the settings.
A computer's motherboard is made up of many essential components including the complementary metal-oxide semiconductor (CMOS) battery. Without this battery, a computer cannot properly function or even boot at all. While a CMOS battery is designed to last up to 10 years, it is possible for it to weak…en and suffer failure, which will become evident in the computer's performance. R ( Full Answer )
C omplementary- M etal- O xide- S emiconductor. This refers to one of the technologies used to make integrated circuits ("chips"). Another common technology is Transistor-transistor Logic (TTL). In reference to the IBM PC and compatibles, this means the RTC's (Real-time clock) CMOS RAM memory, whi…ch keeps track of the time, date, and BIOS settings. The CMOS and the RTC are powered by a rechargeable battery on the motherboard that keeps them on even when the computer is off. However, should this battery run out, the time and BIOS settings will be lost and they will have to be manually re-set. ( Full Answer )
Once the battery is replaced turn on the computer and resetting the CMOS values to the defaults. After the values have all been entered make sure to save the settings before exiting. Many CMOS setups allow you to press a key (such as F10) to save values and exit all in one action. If after following… all the above steps you continue to experience the same error when your computer starts or your computer is still unable to keep the stored values it's likely that you're experiencing a more serious issues. Most likely causes are bad power supply or bad motherboard. ( Full Answer )
CMOS stand for Computer Memory and Operating System. A CMOS battery is used as an emergency back-up to keep information you have stored in the phone in memory from being lost if the main rechargable battery runs out of charge. This would include things such as your preferences, contacts, missed/rece…ived/dialed calls, downloaded ringtones, etceteras. ( Full Answer )
In business ad finance, a CMO is a collateralized mortgage obligation, a type of complex debt security that repackages and directs the payments of principal and interest from a collateral pool to different types and maturities of debt securities. CMOs were first created in 1983 by the investment …banks Salomon Brothers and First Boston for U.S. mortgage lender Freddie Mac. While there is nothing inherently wrong with pooling assets in a vehicle like a CMO, the use (or abuse) of CMOs backed by loans of lower credit quality, such as subprime mortgage loans, led to defaults, which in turn led to the failure of several investment banks and banks and subsequent recession in the United States in 2008.

C MOS is the complementary metal -oxide semiconductor which is used to hold dates, time and system setup parameters.
It keeps so called internal hardware time and settings related to current hardware configuration, boot order and so on.
Most PC motherboards use a coin cell battery as a CMOS battery backup for BIOS settings. Most common battery used for this application is CR3032 and can be easily replaced. You can turn off the computer, remove power cables, open the machine and locate this coin cell on the motherboard and remove ol…d battery from the socket with a plastic tool or your finger nails and then insert a new one in the socket. If using a metal tool/screw driver be careful that you do not short upper and lower side of the coin cell (which can cause a short circuit, can create a spark and will damage the battery).

You will have to run to the store, CVS, Walgreens, Walmart etc. and pick it up. It is a CR-2032 button battery.
The primary thing that happens when your CMOS battery dies is thatthe BIOS settings return to default. The time also resets which cancause problems with software.
Your best bet is to remove all system batteries, and the power cord, then remove the CMOS battery, and wait like at least 20 minutes. Then put the CMOS battery back in, and then the system batteries, and power cord. You will have to set the clock, and boot order, as well as any system specific setti…ngs. I got that you have to remove the cmos battery. My Question is about just that. what comes off the back first. I have a Acer Travel Mate 6460. I am not opposed to removing the back cover and getting to the Cmos Battery. I just need to kn ow the process. I don't want to cripple the machine for ever being ignorant. I need instructions with a couple pictures or plans so I do it correctly. Do you have any plans or scematics for the Acers?.

After taking apart the laptop (see instructions at http://www.takeitapart.net/forum/index.php/topic,5.0.html) I found there is a CMOS battery under the keyboard, but it is soldered to the motherboard. This doesn't make it useful as a reset. I did not find a jumper or any other reset switch interna…l to the laptop. My research seems to suggest that holding the power button for 30 seconds is supposed to reset the CMOS. Unfortunately, that did not help in my case, but may for yours.

Most computers use a standard 2032 type battery. These can be purchased at any drugstore, department store or electronics store. It is always a good idea to take the old battery with you to ensure you buy the correct battery.
BIOS = Basic Input Output System CMOS = Copper-Metal Oxide Semiconductor BIOS is the interface which is built-in to a computer system's firmware used to configure the computer system hardware in very basic ways. BIOS can be used to enable or disable hardware integrated into the motherboard such… as IDE controllers, USB hosts, audio controllers, video, and more. It is often accessed by pressing F2 during startup, but this can change from manufacturer to manufacturer. CMOS is a type of circuitry often powered by a battery which allows the information in BIOS to be stored. If the CMOS battery is drained or removed all the system configuration data in BIOS will be reset to factory defaults every time the computer is shut off. These small batteries are also commonly used in calculators, hearing aides, and wristwatches. Due to the close relationship between the BIOS and the CMOS in the computer system, the two phrases are often incorrectly used as synonyms for each other. Some users will refer to opening the BIOS menu as "going into CMOS" or replacing the CMOS battery as "fixing the BIOS battery." However, none of this is seen as grammatically incorrect in common day-to-day conversation. ( Full Answer )
Actually it's "SCMODS" not cmos and is an acronym for "State County Municipal Offender Data System"
If the CMOS battery dies you lose the settings that are held in the BIOS (Basic Input Output System). These include settings such as date/time, boot order,etc.
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 ha…d 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.

All AT computers (80286 processor) or later require a small battery on the system board that provides power to the Complementary Metal Oxide Semiconductor (CMOS) chip, even while the computer is turned off. This chip contains information about the system configuration (e.g., hard disk type, floppy d…rive types, date and time, and the order in which the computer will look for bootable disks). The CMOS battery allows the CMOS to preserve these settings. ( Full Answer )
I would have to say that there is something bad in the circuitry of your motherboard. I would contact the manufacturer to see if you can get your mobo replaced because a CMOS battery should not do this.
You won't find this answer in Dell's service manual and I have notfound it on the web but I have finally located the battery It is onthe bottom of the mother board and it is soldered on.you need toremove everything from this computer case to get the main boardout. Dell expects you to buy another boa…rd to fix the problem. I'mstill trying to locate the exact replacement. ( Full Answer )
The cmos battery (usually a 3V 2025 or a 3V 2032 part) keeps the information in BIOS from being lost when the power is off on the computer. If you remove the battery, the BIOS will be reset to default.
I think the battery you are talking about is also called a "BIOS Battery", and is used for keeping the BIOS settings of the computer stored properly, even when the usual power supply is removed. This means that you don't have to set the time etc. on your PC whenever you unplug it from the wall.
Test the voltage of the battery. if the voltage is below the rating of a new battery (For a CR203 it would be 3.6 volts) it is defective.
\nif it's dead you need a new computer anyways, they're rated for 15 years or so
You need to replace the palm rest assembly it is part number 6G500. The battery alone is not available.
Not so much a CMOS battery, but the data in NVRAM (startup-config) is in some models powered by a battery, which is pretty much the equivalent. In other models (among them the 2600 series) NVRAM is implemented with an EEPROM which does not use a battery.
The CMOS battery saves your computer BIOS settings and the hardware clock. Without this, the computer would not be able to remember the system time or BIOS settings while it is shut down.
You will lose all custom settings in the BIOS, and the BIOS will revert to the basic default every time the computer is restarted.
That battery is not easy to get to you'll have to almost completely disassemble the unit to get to it. See the related link to download the service guide the look in the index for RTC battery replacement.
The battery would likely not fit in the holder. Although it would provide the correct voltage, it would not last as long as the proper battery would.
Complementary Metal Oxide Semiconductor . it is the the sensor on DSLR cameras. In lay man terms its the film in the digital camera.
The only watch like battery on the motherboard. Its silver colored and sits in a liitle Pod
You have to open up the computer and replace the button battery by one of the sampe type. I would recommend letting you system manufacturer do this if its still under waranty.
CMOS stands for Complimentary Metal Oxide Semiconductor. CMOS is a technology for constructing integrated circuits. It is widely used in Microprocessors, Micro Controllers, Static RAM. It is also used in Analog circuits such as image sensors. CMOS was patented in 1967 by Frank Wanlass. CMOS is somet…imes referred as COS-MOS i.e complementary-symmetry metal-oxide-semiconductor.

In almost all modern PC's there is a battery located inside the computer. The battery is the common CR2032 battery. It can be found in most stores that have a decent battery selection. First, unplug the power cable from your computer. To access the battery, you must first remove the case cover. I…f you are unsure how to do this, consult the manual for your specific computer. Most commonly, the side of the tower case opposite to the side with the keyboard/usb connectors can be removed with two or three case screws. Once you have opened the case, locate the motherboard. It is the largest circuit board. The USB and Keyboard connectors are on this board. Look around an locate the CR2032. There will be a clip holding it in. Press the clip aside with a small pen or screwdriver. The battery will pop up and you can remove it. Replace it within a few seconds, and you won't have to reset the time and date on your computer. Replace the case cover, then plug in the power cord. Go ahead and power on your computer. If an error is shown that says that the date and time are not set, follow the instructions given to enter the BIOS setup. Use the arrows to get to the date and time, and then use the -/+ keys to change them. Look for the information about saving and exiting, and do so. Your computer will now reboot. You're done! The whole procedure takes generally less than 5 minutes unless the computer is impossible to get to. ( Full Answer )
CMOS stands for Complimentary Metal-Oxide Semiconductor. It is the manufacturing technique used to create the main CMOS chip on your computer that stores the initial settings your computer uses to start up. In CMOS setup, you can change the date and time, boot order, boot device, implement security …settings, as well as many other things. ( Full Answer )
CMOS ( c omplementary m etal o xide s emiconductor) is that type of technology that is used by nowadays computers to keep our current time and date and system setup parameter's. We often see a cell mounted on the motherboard inside the system case, that part is called CMOS and the that small ba…ttery cell is been giving the power to CMOS to keep the BIOS setting (all sort of time, date and system setup settings etc.) been working if we plug out the power cable.

CMOS stands for Complementary Metal Oxide Semiconductor, and is a type of technology that uses very little power to operate. It is not unusual that a CMOS battery lasts 5 years - it is a type of watch battery. The CMOS memory in your PC is used to store configuration data, such as how much memory yo…u have, what type and number of hard drives you have, and what if any password protects your computer. The CMOS memory is used by the BIOS (Basic Input/Output System which is stored on permanent or semi permanent memory. Together, the operate your computer prior to its accessing the hard drive, running the POST (Power On Self Test) and setting configuration. ( Full Answer )
CMOS is a type of sensor built in to an SLR camera.. Another sensor you may come across is a CCD sensor witch tend to be smaller.
You have to get to the motherboard and pull up the CMOS battery, its a small circle. Then replace it with one with same volts. And make sure you put + and - the right way.
The settings in your BIOS would be reset to factory default. E.g. The time on your system would be wrong every time you booted up.
The CMOS remembers the time and date settings of the computer, and also remembers the Hardware settings.
For starters, CMOS stands for Complementary Metal Oxide Semiconductor. CMOS is used in a form of non-volatile memory. To be non-volatile means means that it will not lose the data, even if the power supply dies or the power goes out. The CMOS battery also has a cool little trick it does - it tells t…ime for your computer! That's right, at the bottom right (or upper right, possibly, depending on your liking of the Windows task bar) where it states what time it is, that is powered by your CMOS battery. Interestingly enough, it involves half-life, the process is really complicated and beyond my reach, however the substance that makes this half-life possible is completely natural! Thank you, nature!

CMOS is a type of material, not a specific type of processor. That is short for Complementary Metal Oxide Silicon. CMOS devices tend to use less power and tend to be faster than their older counterparts. So a CMOS processor is a processor made using the CMOS material. For instance the V20 chip is a …3rd party CMOS variation of Intel's 8088 CPU. The V20 is 10-20% faster and uses less power than the 8088. ( Full Answer )
There are none. One is a battery which is used to provide passive power to the CMOS chipset to keep it from clearing itself.
CMOS batteries can be purchased at a range of online, local departmental stores with electronic departments and hardware stores. It is usually a good idea to research the brand and type of battery required by visiting the local shops and looking online for the best prices to get the best deal.
Removing the CMOS battery will not prevent the computer fromturning on, it will only cause the information in the CMOS RAM tobe lost (while the computer is turned off). When you turn on the computer after the CMOS battery has beenremoved, while it will turn on it will most likely not boot the OScorr…ectly but will stop in the BIOS and require you to completelysetup the CMOS parameters again before you can tell it tocontinue..
