|>So, did you update the BIOS or not? From #4 above it sounds like you had someone else flash the chip then?|
Yes, someone did this - the IT service firm.
>Do you get video during the POST at start up? If not, try a different video connection if one is available?
No, when I try to run computer screen is black and POST does not show up. I checked another video card/connection, no effect.
>As mick has pointed out, you may have damaged the board if you did not unplug the computer prior to removing the battery. You also need to practice proper static discharge procedures.
I unplug the computer power supply, before removing the battery.
>You also stated you removed the cables from the board. Are you sure they are now connected correctly?
Yes, I'm sure. RAM+CPU+VGA onboard+power supply, is enough to run POST...
>You could test the board by booting with ONLY the following connected.
CPU/Hsink/fan, 1 stick of RAM, power supply to motherboard connections, monitor to board and keyboard. NO case to board connections, add in cards, drives of any kind, no external hardware other than the aforementioned. You do need a sound device, which should be integrated on the motherboard.
I tested, no effect.
>You start the board by shorting the two power switch pins momentarily with screwdriver or other. You should get a post up to an onscreen message indicating there is no bootable device. If that doesn't happen then try removing the stick of RAM and rebooting. You should then get an audible error.
Starting computer using this method have the same symptoms. I don't get onscreen message, screen is black. I don't get any audible error, even when i remove ram. Speaker is connected correctly.
