SOURCE: Problem: set wrong jump Cmos

Do you still have you're manual?
Go to page 1.18.
If the bios jumper is not over pin 1 & 2, than make it so.
While the jumper is on 2 & 3 you're bios clears it's self every time you boot the system. (This is why you're clock does not keep the correct time.)
Need manual? Click on the link. http://support.asus.com/download/download.aspx?modelname=P4P800-MX&SLanguage=en-us

Good Luck!

SOURCE: I INSTALLED A NEW CMOS BATTERY BUT STILL NO EFFECT

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.

SOURCE: I do have a ASUS P5GC-MX/1333 REV. 3.05G

there are two jumpers side by side. one has 3 pins with same distance between them (for cmos)
and
the other one that has also 3 pings but 1 of them a little bit far from the other 2 (Chasis Intruded)

For cmos,
pin 1 pin2 conected is normal operation
pin 2 pin3 conected is for resetting the bios
if reset caried on jumper must be taken back to normal operation positing


Chasis Intruded worning is shown when chasis jumper removed or put on the pin1 so the jumper can not contact the pin2 and pin3.

You must connect pin2 and pin3 by a jumper and restart your computer. That is al.

How do I fix my CMOS Battery Low error so I can correct the Time and Date since it's stuck on the 01/01/2004 date and won't save in my BIOS?

This is usually a very short and sweet step to complete.
After you have changed the CMOS battery over to a new one all you should have to do is go into BIOS set the date, the time and the year. Save the settings in the BIOS, exit and restart the computer.
You have to set the date, time and year in the BIOS first then change it on the desktop.

The proper battery to use for CMOS is a C2023 coin cell battery.

Hope this helps

Cmos incorect perriferique non specifier

google translated

incorrect CMOS device not specify

CMOS device(electronics)

A device formed by the combination of a PMOS

(p-type-channel metal oxide semiconductor device) with an NMOS (n-type-channel metal oxide semiconductor device). Derived from complementary metal oxide semiconductor device.

The CMSOS is only a battery to store you're bios/mainboard settings.
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..

The moment that you unplug the power and remove the battery for at least 10seconds, the mainboard will reset it self into the 'default-state'.

This can also be done by selecting 'reset to default settings' in bios screen.

Restart your computer
During the boot process you will see on the screen to press a certain key to enter setup usually the Delete or F2 key
this will vary depending on your computer and operating system

Press and hold that key during the boot up process to enter BIOS using the arrow keys load failsafe defaults or load optimized defaults press escape then press f10 to save to cmos to restart

hope this helps

Start-up and shut down problems, When starting up it says, press f1 to continue, f2 to run set-up.... F1 works but I am getting tired of doing this. Now when the computer starts, it stops at...

Hi names Rui,


For your problem the computer may display a prompt to press F1/F2 or any other key to enter setup each time the computer boots as a reminder on how to enter CMOS. However, if the computer asks to press F1/F2 (or another key) to enter setup and does not continue, this may be caused by any of the below reasons.

  1. New hardware has been recently installed.
  2. Error or confliction with settings in CMOS.
  3. CMOS battery is bad or failing.
Solution:

New hardware has been recently installed

If new hardware has been recently installed into the computer, it is likely that you are receiving the prompt "Press F1 or F2 to enter setup" because CMOS needs to verify that the new detected hardware is properly being setup in CMOS. Enter CMOS setup and save the settings and exit. If you continue to get errors continue to the next step.


Error or confliction with settings in CMOS

If no new hardware has been added or you continue to get this prompt verify no error or conflictions exist in CMOS. Press the key to enter setup and verify that all settings are correct.

If your time and date are not set correctly, your battery is more than likely bad. Try setting the correct time and date, save the settings and then reboot. If after turning off the computer the time and date get reset again replace the battery.

If the time and date are correct and everything else appears to be correct try resetting the CMOS values to the defaults.


CMOS battery is bad or failing

If you continue to receive the prompt to enter setup each time the computer boots up and you have attempted to follow the above suggestions, your CMOS battery is bad. We recommended that the CMOS battery be replaced.


hope this will help you.

Bios rom checksum error

The CMOS setup has gotten corrupted. This may have happened if the 3 Volt coin battery on the motherboard is low. If your date and time is wrong, that is a clue the battery needs to be replaced.

If you have a voltmeter, check the voltage on the coin battery. It should be 3V. If it's much less that that, it must be replaced.

Whether or not the battery is bad, you will still have to enter SETUP when you boot the computer after replacing the battery. At boot, it usually displays what key to press to enter setup (DELETE, F2, etc. )

There are several menu screens which you must ensure are correct, according to the hardware installed on your computer.

If this is too daunting, take it to a computer repair place, and they can do it for you.

Good luck!

Ibm thinkpad

The 161 CMOS error means the CMOS/BIOS battery is dead/flat and needs to be replaced.
The 163 CMOS error means the Date and Time could not be updated when you change the Date and Time setting. This is caused by the flat CMOS/BIOS battery.
When you replace the battery with a new one, the BIOS will go back to the default settings, go into to BIOS setting (press F2 when you boot up) and change the Date and Time, then save and exit.
