I just hope you didn't over clock to much to soon and fry your cpu. Which is what it sounds like

Hi,

Turn the computer off and remove the mains power lead. Open the case of the computer and expose the motherboard. Take out the BIOS battery for 10 minutes. The battery looks like this >>>>>


There also maybe a small plastic jumper next to the BIOS battery if you look close enough it should say CLR_CMOS under it. Move the plastic jumper to the other position and push the on/off button, that will clear the CMOS.

If there isn't don't worry, just leave the BIOS battery out for 10 minutes then put the battery back in. Close the case up and the BIOS password should be cleared.


Regards.

It is under a flap under the laptop A little round 3.6V cell.

When your motherboard/CPU board CMOS battery dry or have charge then you can not run to power *********** board.Or CMOS is disable.Please check

1 Power supply
2 CMOS Battery

Open your cpu cabinet cover.
Then Refix RAM memory on mother board.
Remove pci cards from mother board if any.
Make sure motherboard is not ground with cabinet.
Reattach ATX power connector to motherboard.
Pull cmos cell from motherboard for 10 minutes then refix it .
Then it work again.
Let me know if you need further assistance.
Thanks for using FixYa.

Try going into the BIOS and restore factory defaults, reboot and see if the message is still there.

You probably need to replace the on-board battery.

If you know for certain that the Power Supply is good. (tried another in there) then you have a bad motherboard. No, the CMOS battery will not keep it from coming on.

Change the "battery" on the mother board. Sounds like it's weak and there's not enough voltage to maintain the BIOS memory.
