When the machine boots up it says that the CMOS Settings are Wrong CMOS Date/Time Not Set but after I set it and restart the computer it asks the same each time?

Press F2, then et the time & date in the BIOS, then choose save & restart

You need to have the battery in order for system to boot, however, you can reset it.

you can load failsafe or optimised defaultsusing the arrow keys you can after you make any changes in BIOS press Esc then press the F10 button save to cmos to restart
CMOS is an on-board semiconductor chip powered by a CMOS battery inside computers that stores information such as the system time and date and the system hardware settings for your computer..
this will reset your cmos

try to change your cmos battery,and first boot your hardrive,and set your time and date properly then save your settings take a look if your settings will be save.if yes,that means your cmos battery is the isue.

try to boot and when it asks to set the time and date ..press F1 to go to the BIOS settings and in there save like it is with F10..and enter ..will start anyway and you will set the time in windows..
or ...go to bios directly by pressing F10 if it is a HP computer or ..F2 for any other laptop ..and in there on the time settings just set the time and the date from the arrows and enter ..
if you have other problems and you opened it ...you will have to remove the Bios battery to default it to the factory settings ..this will eliminate any passwords that might had kept you out of bios...if you do not see the battery ..remove the wireless card and see if it is under it ..

Hey!

Try checking the Time and Date settings of the computer. Time and Date settings can greatly affect programs that access the internet. Try correcting the Time and Date settings. After correcting it, try browsing some websites where you get certificate errors.

After doing that, restart your computer. If the Time and Date is wrong again, it means that there is a problem with the CMOS battery(complimentary metal oxide semiconductor). This battery saves the basic settings of your computer which includes Time and Date settings, boot up device settings, etc. If that's out of charge, best option is to replace it. Here's an sample image of it. It's just like a watch battery but a bit bigger.

Hope this helps! :D

The date and time are incorrect. The CMOS battery may need changing unless you haven't set the date and time.

Press either F2 or Delete on boot.

Just replacing the battery will not set anything. You have to do the setting of the values. If you can run setup by pressing F1, then do that and set all the settings and then save before exiting. Make sure you save the settings by choosing the correct exit and re-boot option.
If the settings cannot be set nor saved, then make sure the poser is off or pull the plug from the wall outlet, then short the bios with the jumper to short the bios. This will reset the bios to the default settings. Turn on the system and then go to the bios settings and set the settings. Then use the reboot option to save the settings.

first load bios default settings then save.
then set your date and time.
detect your hard drive if your harddrive has win xp u not need to reinstall u just detect your hardisk then restart your sys will be boot with hdd.
