Bios/Cmos

asaunders12
I have a Compaq Presario SR1303 model #CNH5030FTV, product #PP150AA that was giving me problems. I thought it might be in the bios and looked for the OEM bios setting but could not find the info. I decided to flash the bios but could not find the correct one. So I tried making some generic changes that didn't work. I then removed the CMOS battery in an attempt to return to factory settings. This didn't work as well. HELP! What can I do now or can someone steer me to where I could find the OEM setting for this motherboard?

Thanks in advance.

    Usually pressing F1, maybe F10, right at first power up will get you into the BIOS.
    If you have already attempted to flash the BIOS with an incompatible version, then
    you may have problems, and will need to contact Compaq/HP for assistance.
    Maybe this link will help...

    You might be able to find an updated BIOS firmware from HP (Compaq)

    My question should show that I have no problem with entering bios my problem is having changed the bio. I need the OEM setting for the bio, this way I can know what changes the CMOS battery reset made and correct. But thanks for your effort.

    OK, if you can enter BIOS setup, search around for "default" settings.
    I don't have my Compaq notebook with me to check, so not sure, but
    if memory serves it is somewhere along the bottom row of options, to
    load default settings.

    Also remember to check the current Date & Time are correct as well as Saving the Changes when you go to exit the BIOS.

    Something I've had to do on a few machines was to remove the battery and with a short wire with clips on each end, shorted the plus and minus on the battery holder. This disipates any chage that may be held in a capacitor. Some newer machines have caps hidden under chip sockets that hold the firmware for the BIOS. This also blanks the FLASH chip and forces the unit to boot to default settings loaded from the firmware chip and not the flash BIOS. Older machines have ajumper berg near the battery and would be marked for a reset position. Dead or failing CMOS batteries exhibit very strange faults that are random and intermittent.

    A couple of notes on clearing the BIOS settings in the CMOS memory.

    If the computer is plugged in and getting power, removing the CMOS backup battery will NOT reset the BIOS settings.

    Even with power unplugged, it can take half an hour or more for the voltage to drop low enough for the CMOS memory to reset.

    If you want to reset the BIOS settings, it is always best to set the Clear CMOS jumper and then press the power button. Remove the jumper, and then start up and set the BIOS settings.

    As noted in another answer, a weak CMOS battery can cause some very strange and intermittent problems. At 9 years old, the CMOS battery should have been replaced at least once by now.

    For most systems, there are only a few BIOS settings that you need to be concerned with.
    HDD and Optical drive detection.
    Boot order
    Num Lock Status
    Date and Time.

    If your system has onboard video, and you are using an alternate video card, you may need to set a video option.

    If the system has been running properly, and then started having problems, flashing the BIOS is not the answer.

    Looking at the HP information on this 9 year old computer, my first thought is that you have a hardware end of life or failure issue.

    Take a look at this website to see pictures of damaged motherboard capacitors.

    I suspect that you will find at least one bad capacitor on the motherboard.

    Also, after 9 years, of software installations and Windows updates, the Windows installation might have enough bad links and corrupt settings to cause the system to slow down significantly.

    And as you only have one year of security updates left for Windows XP, it just might be time to put time and funds into a new computer rather then trying to get a little more out of this one.
