    Recently bought a HP Pavilion a450n with:
    3 GHz Intel Pentium 4
    512 MB DDR SDRAM
    160 GB Hard Disk
    Windows XP Home Edition
    coupled to a HP Pavilion 19" Flat LCD Monitor.
    Unfortunately, I seem to have developed a common HP problem where the computer will not wake from the sleep mode. The keyboard and mouse will not input, and cycling power to the monitor wakes the screen to the "Going to Sleep" display, then the monitor powers down. After cycling power to the CPU (even removing all power and cables), the computer powers up to the "Going to Sleep" display and then the monitor powers down again. Video cable and pins look good and undamaged..and the boot up doesn't sound or look normal. Took it into to a local shop where they said the NORTON load was corrupted and reloaded, and then installed Windows SP2. Back home..same thing. Believe this is some problem inside of BIOS but don't know how to get at it or fix. Any assistance before I take my aggression out on the hardware would be much appreciated.

    Try "Flashing" your BIOS...

    Look for the little battery you will find in a corner of your motherboard...(it's round and silver most of the time)

    Pop it out and wait anywhere from 15 minutes to 24 hours...your choice.

    Also, go ahead and disconnect trhe power from the motherboard itself.

    After your dersired time has expired, replace the battery and the power to the motherboard and restart your computer.

    The BIOS should be reset to the factory defaults. Reboot your computer and try everything again.

    Let us know how it goes!

    The advice above is "resetting" the BIOS, "flashing" it is an entirely different (and unadvised) operation.

    Some desktop hardware simply does not like hibernation or standby. The feature is designed for laptops primarily, and I have seen major desktop makers actually advise against it.

    I have run 15 different PC's since 1981, and have never found a desktop PC that would operate reliably after resuming from standby or hibernation. Often its related to the software loaded as well. Some simply will not do it.
