Read this only if you are sure that you have replaced the correct type of battery & you have set the jumpers to the default locations.

It is not the problem with the battery or the charging problem (Actualy CMOS battery is not Recharable ) most cases.

The problem is the battery holder in mainboard where we put the battery IN. eventualy or accidently these Pins from the Battery Holder are made loose or not contacted with the battery.i had the same problem and the solution was to adjust the Battery holder to seat the battery in proper way.

I do not think you fixed the CMOS battery - (backup battery = CMOS battery)
According to the error codes, you have a dead backup battery and the time is not set. Makes sense?
(Dead battery.) 1. Go to Checking the Backup Battery
2. Backup battery.
3. System board.
(Time and date were not set.) 1. Set time and date.
2. System board.

Go to Find and download the user manual, and the "hardware maintenance manual."
Do you know how to get into bios/setup?

Start with the machine OFF. HOLD DOWN and CONTINUE TO HOLD THE "F1" key.
WHILE STILL HOLDING "F1", turn the power on, and CONTINUE TO HOLD "F1"
This will get you into the bios "setup." You should check the date, bootup order, etc, and reset.
I would check the "wire" you think you reconnected---you may just not have actually reconnected it.
The "hardware maintenance manual" shows you how to maintain this machine, and it explains the meaning of the error codes.

This will get you started on looking for the manual:

Strike F1 to continue, F2 to run the setup utility

Got to BIOS by pressing F2,check or any floppy setting and disable it even in boot order setup.This will solve your problem otherwise replace the lithium CMOS battery.

As you have reset the BIOS setting to it's default setting.Floppy drive is enable by default whether your system have a physical floppy drive or not.

CMOS Battery do no work

Just change your CMOS battery with a new one and after that goto the bios settings and update the time and dare.
After that just save the settings and then check that the warning message is coming or not.

If its coming then it means you need to change the CMOS jumper settings.

Always f2

If I understand correctly your saying when you exit the cmos, id doesn't save your changes. Make sure when you exit you select the option to save and exit. If that doesn't work, your cmos battery is dead. Look in the mobo manual to find out what replacement battery you need.

Please help me


Check ASROCK P4i45GV R5.0 User Manual Page 17 -

Note: Check Page 11 for the CLRCMOS0 location on the motherboard. From the picture CLRCMOS0 is number 18. You can locate CLRCMOS0 just below the CMOS Cell Battery.

Turn off the computer and unplug the power cord, then use a jumper cap to short the pins on CLRCMOS0 for 3 seconds. Please remember to remove the jumper cap after clearing the CMOS. If you need to clear the CMOS when you just finish updating the BIOS, you must boot up the system first, and then shut it down before you do the clear-CMOS action.

P4i45gv asrock motherboard problem

it sounds as though your cmos chip is damaged; if you are unable to get as far as the bios when pressing F2 or Del on boot up, then you may need to replace the motherboard. Also reseat your memory as that is another cause and check the Cr2032 cmos disc shaped battery as this may be flat and the original cause of constant reboot cycle. Lastly this also happens if you have changed any hardwre in your pc as windows will not boot if there have been major changes to hardware and windows will have to be repaired using your XPcdrom.
