This sounds like your battery may be bad or not locked into place fully. Also on the mother board there is a cmos jumper that is used to clear your bios check to make sure the jumper is set correctly an also inspect the jumper to make sure it will make good contact to the jumper posts. Good luck I hope this helps. Also when you set the time in your bios make sure to exit with f 10 key or whatever the save and exit key is for you bios.

Battery dead & BIOS reset. CD & DVD drives lost.


first you will need to replace the cmos on the system board(or have a qualified computer service tech. do it). then you will need to access the bios settings by Pressing F1 immediately after powering on the computer. once in the bios, you can set the correct date and time. Also, you will need to check the drive settings to verify that the hard drive and any CD/DVD drives are recognized. once done, then exit the BIOS being sure to chose "save and exit", then allow your PC to boot normally. this should fix your date and drive issues. if not then the motherboard may be defective.

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.

As i turned on the monitor the screen shows CMOS WRONG PRESS F1 TO SETUP PRESS F2 TO LAOD DEFAULT VALUE


hi,
first of all check the main battery back of ur machine by unplugging from the mains power supply. if machine shuts off, then u have to replace the battery.and then set the date time etc by pressing F1. and then save it and exit set up. next it will not ask for F1 or F2.

if the main back up battery is ok, then another possibility is the CMOS backup battery of ur machine have some problem. that's why it loosed all the seted parameters. then u have to replace the CMOS battery of ur machine. normally 3V battery. then set the date time etc by pressing F1. and then save it and exit set up. next it will not ask for F1 or F2.
ok

This is the problem with your "Bios Battery" which on the motherboard. Maybe there's none or it's not functioning anymore. Just replace it and the "cmos checksum bad" error message will go.. for your reference, i include some pictures.. herein. 0748746.jpg

Hi melnavz,


Hello!
Make sure that the battery hold firmly in the mother board and should no be drain out or busted to hold the time setting in the cmos. this is the only things that you need to observe. if the system keeps on asking the setting then battery is the main problems that cannot hold the time setting in the cmos.

tell me if problem still occur.

Faulty time settings p5rd1 vm


Hello!


That's the 2nd time i hear that kind of problem. Your mboard battery is new, and you did not press "f1" at first start.

so i guess , the cmos time is not change, try go to the bios setup and load "bios setup default." after that change the time setting on the bios. please find time setting and set it with a current ime in your area. after setting press 'F10" to save and exit the setting, the system will restart.

may this help!

best regards, melnavz
