BOOT falilure after RAM installation

The problem maybe the RAM, it is faulty or just needs reseating to make proper electrical contact.
Reseat the RAM and then boot up your laptop. If it still does not boot up then remove the RAM module/s and take them to your friendly computer repair shop and get them to test the RAM for you.

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.

Hi promano67

When you "start" the computer, and the {"Screen"} displays a "Error Message."[CMOS] "error checksum!"

Settings: "Default" loaded.A "checksum error" shows that:

The ("Boot-up Settings "have been changed?"), ie. "Booting OS."

*Boot File 'missing'.

"This can 'occur' if the computer was "shut-down unexpectedly."

Force Shut-down : Power lost; due to 'low battery...'

A ("Power Surge") can cause this 'problem' also.

"What 'happens is that the [CMOS] settings are lost!".
"To fix the problem!"

Do the following:

• "Restart / Boot the computer.
  

• Next, verify if the 'error message' displays?
  

• If you are still getting the message?
  

• "You will have to "Remove the CMOS battery form the computer!"
  

• Shut-down the computer.
  

• "Unplug the computer from the {Wall Out-let}.
  

• Remove the Lithium battery from the "Notebook."
  

• There is a compartment (underneath) the "Notebook that 'store' the CMOS battery."
  

• "You will need a {very small Phillips screwdriver}. *Remove the CMOS battery for: [30 minutes].
  

• !Important: If you have to do it again?
  

• Remove the CMOS battery for a {'longer amount of time'}.
  

• Replace the "CMOS battery."
  

• Next, "Only plug the Power Adapter into the computer.
  

• "Do not - replace the "Lithium battery!"
  

• Once you have completed these 'task'.
  

• "Restart the computer."
  

• "Press the [F2] key, to 'enter' the CMOS / BIOS Setup!"
  

• Next, 'reset' (all) "Values to the Default Settings."
  

• "Press the [F10] key to 'Save' the changes!"
  

!Important: "Take a 'moment to rate the help', so I can get 'credit' for the work.

Thank you!" - paul7of9

I received an IBM laptop with same issue a few months back. The error message due to the drained out CMOS RTC (coin-cell battery), which retains and other BIOS settings.
The system is OK and all you have to do is to get the CMOS/RTC battery replaced by the a professional.
Good Luck!

Had this problem once before on boot up, but can't find the fix for it.
On boot up, I get the message that says "battery voltage low" and I have
to hit F1 to continue or F2 for setup. My battery voltage is NOT low.
Does anyone have the solution to this as it's quite annoying to have the
boot stop and wait for the F1 command? I promise NOT to lose the solution
again. Thanks.


Just a guess, but is it referring to your CMOS battery and might therefore
be an early indication that it needs changing?

Normally when this happens it is the CMOS battery in the computer that needs replacing. Not the laprtop battery but the internal battery.
hope this helps.

Hi im Rain.
Have you tried changiong the CMOS battery? Im sorry but the big Y2K was just the panic of people not knowing what will happen. There were no computers Reported to have been affected by the Y2K scare. Try changing the CMOS Battery If that fails then we can look into other things that may be affecting the BIOS

you need to go to cmos or bios setup, set all the date and time and proper boot setting there save and exit, it is a cmos or bios failure that causes these problems try replacing the cmos battery if the message still continues

Dear Don't worry, there are some options you will have to press or check one by one "F1or F2 or F8 or F10 or F12 or del. Now, You can enter in CMOS setup.

Hi, and welcome to FixYa
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.

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.

Error or confliction with settings in CMOS
If no new hardware has been added to the computer or the new hardware has been removed and you continue to receive the error, it is likely that there is an error or confliction with the CMOS. Press the key requested to enter setup and verify that all settings are correct. If everything appears to be correct try resetting the CMOS values to the defaults and/or Reset Configuration Data. Additional information about how to do this can be found on document CH000976.
If all settings appear to be correct, save changes and exit CMOS setup. If the error continues to appear, enter setup again and restore all CMOS values to default.
· See our CMOS page for additional help and information with the CMOS.
· Additional information about getting into the CMOS / BIOS setup can be found on document CH000192.
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, it is also possible that the CMOS battery may be bad or failing. Generally; when this occurs, the computer is not holding the time or date correctly. If this is occurring it is recommended that the CMOS battery be replaced.
