    Hi,

    Where can I find CMOS battery in ASUS A6RP ? I need to reset it because i cannot get into bios settings. Notebook hangs on first screen (with asus logo). There i can press F2 to Amibios settings, but there is only one screen and nothing to change.

    Regards

    After you have pressed F2 what screen do you get?

    Try first the > o < button on the belly of the notebook (pinhole button, like the mechanical eject button on ODDs). That should also reset BIOS settings.

    Otherwise see here for related disassembly manuals: http://forum.notebookreview.com/showthread.php?t=122632#disassembly

    Yes, it is logical. Plug in your HDD (both cables) so NB can boot from it

    So with the HDD removed and the reset button pressed the system will still not let you into the bios?

    It would seem then that the HDD has gone bad. Real bad -- like, electrical problems of some kind.

    Or, more likely, that the ATA controller is not working properly.

    A good way is to test the HDD in another system, or in an enclosure.

    Another possibility: you have either dead or disconnected keyboard that is why you can't enter BIOS and NB can't boot

    Sorry but it sounds like your HDD is dying if not dead allready.

    Do you have access to a Laptop to PC HDD converter cable/caddy?

    Is your HDD SATA or IDE?

    Duh? How silly of me! LOL!

    If you can get a laptop to pc IDE converter you may be able to plug the HDD into another PC and see if you can access it that way. If you can you could then run a chkdsk /r

    Just read some previous posts and it looks like I'm just confirming what E.B.E has said. Dam when did that post appear? I must be blind! LOL!

    Well, let's try once again

    1. unplug your hard drive.
    2. enter BIOS
    3. set BIOS to 'default settings' and save on exit
    4. Plug in hard drive
    5. Run again

    Do not forget to remove battery when needed.

    I think it is dead piece.
    It can be hard drive or motherboard or something else - I have no clue what else can be done

    Service, or like we said before if you have an enclosure you can test the HDD. If it's not the HDD I think the ATA controller or something else on the mainboard went AWOL. :)
