my system clock slows down if I shutdown system. is it b'coz of my cmos battery is being low?

I believe most CMOS batteries are 2032 batteries.  You should be able to find them anywhere and they aren't really machine specific.  I'm not sure about laptops though.

If you are doing this for nefarious reasons (beating out a 90 or 120 day trial version of software), you can't "disable" the clock, however you can adjust its time in the BIOS.\n\n    Another possible way is to remove the CMOS battery on the motherboard.  I do NOT reccommend this.  It will cause the internal clock to reset to midnight Jan 1, 1980 every time you start up.  The internal clock is critical to a lot of internal functions, and is asking for problems.\n\nIf this is what you're going for, just buy the software, or get freeware(Linux).  It's too much of a hassle to deal with this every time you turn on your PC.\n\nIf you are asking this because you are tired of seeing the time in the lower right corner of your screen, that is another matter.  Just right-click on the start button, and select Properties.  Select the Taskbar tab, and uncheck the "Show the clock" checkbox.  Click OK, and you're all set.

This is normal, if you have not used the computer for a pre-set time. If that is not the case, check the battery.  Try another one if available.  If the problem is not the battery, then you may need to check the setting of AMP/ACPI in either CMOS or Power Options in the Control Panel.  To access CMOS, you press F2 or F3 or F11, or one such keys: as the computer starts up (watch the screen carefully during startup)and it will tell you which key  to press to enter CMOS. Go to Power Management and look for ACPI.  Set it to "Off" .  Then restart the computer.  If you still want it to turn itself off after, say, 30 minutes, go to "Control Panel" after the desktop is available, choose "Power Options", and the computer will lead you throuh the rest. The last settings over-ride CMOS.

Its due to the Power Saver option being active. You can change the settings from Start>Control Panel>Power Options.

if your bios is losing its information check the battery on the mother board. It is one of those round watch batteries.

It's probably the cpu temperature alarm.\nDepending on your board, there is a temperature alarm built into the cmos.  If it is alarming, maybe your cpu is getting too hot.\nCheck your fan and make sure it's working well.  You may want to replace it with a bigger fan to keep it more cool

Good information to help you resolve this would be:  new or used computer?  It could be shutting down for a multitude of reasons...  The first to come to mind is temperature.  Most motherboards shut down a few degrees before the processor's thermal breakdown point.  You may want to see that your heatsink is seated on the processor properly, and that any and all fans are functioning.\n\nAnother common culprit would be a virus.  Look for a free program that will let you do a boot time scan of your system.

Sure! Make sure any scheduled tasks use the advanced mode to bring system out of standby.\nSTART, ALL Programs, Accessories,System Tools,Scheduled Tasks - then choose:\nProperties, Settings, Wake the Computer to run this Task

Computers have TWO clocks built into them.. one being the CMOS clock,, the other being the Real Time clock..The battery keeps power going to those when the computer is not plugged into electric

you can turn it off and then it will be extremely slow or you can turn it on and it will be fast and working lol.\n\nSeriously the BIOS should let you over clock it but its not a good idea :)

Because your CMOS battery is probably dead. It needs to be replaced with a 3V lithium CR-2032 battery found at most department stores or electronic stores. It is about the size of a quarter and is on the motherboard in the computer. Remove the old one (which is easier said than done) carefully with the aid of a tiny flathead screwdriver. Replace.

It could be due to any number of reasons. Try and narrow the problem down.\nIs it when you are running a particular application? \nHave your recently installed a new applications or hardware?\nIs it at a particular time of day? \n\nIs the CPU overheating?\nIs the RAM OK?\nLoose connector somewhere?\n\n\nHope that helps some :)

This is because your computer's power is so low that it needs to keep restarting to prevent the battery from dying out.  When it restarts over and over again, less power is utilized.  If you don't have any way of restoring power to the battery, you should just continuously save your work every several seconds.

You are probably shutting it down when you still have some programs running. Close all programs by yourself before shutting it down.

Try opening the time/date,,while you've got it open tap the space bar a few times..If this don't help then your CMOS battery is going bad.

First thing : are you using a licenced version of the operating system ?. IF yes..\n\nThe computer must be waiting for some background process to get closed before shutting down. thats why it is taking time. \n\nThere must be some program which might be not responding at the time of shutdown and the pc has to wait for it \n\nThere may be other factors also.

Actually you didn't cut the power off. Because you still had the system battery pluged.  CMOS always has a power in it, unless you unplug the small system battery. This is how it can store current time, date, and basic hardware settings.\n\nI think that thing it is dead...
