Question about System Power Supplies
I changed the batt on the MB and now I have no mouse or keyboard and the monitor is black. No Nothing at all. I put the old batt back and that didn't help. What caused it to do this.
Sounds like your mother board is fried, when you change out a battery sometimes static electricity builds up on your finger tips and zap and in most cases you wont notice it, it only takes a little bit to fry a mother board.

Tips for a great answer:
One bad lead can cause a computer to continue on a cycle or
to shutdown or fail to detect/ boot up a computer hard drive
Test all leads that attach to your hard drive including
the leads from your
"((motherboard to your hard drive))" make sure they have a secure connection and
are not faulty or just replace them they could be faulty
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electrical extensions or just replace them they could be faulty a computer needs its connections to continue its cycle and have an end so any faulty leads will end up with a computer error
try blowing out all of the dust from your keyboard using a fine air blower from an air compressor making VERY sure there is no MOISTURE in the lines.
dust causes static which causes lots of problems with a computer and its parts
click start control panel keyboard hardware then properties you should see driver details,you will have options to update driver,roll back driver,uninstall
