Cmos checksum bad, cmos date/time not set - press F1 to run setup Press F2 to lo

[Frankielee]

I have probllem with my cp booting up. It keeps telling me cmoschecksum is bad camos dae/time not set. Press F1to run setup. I get the same answer. I disconec my power from the rear of my computer and disconnect the power supply from my mother board. Then I take the battery out and move the cmos setting to the second & third pins for 6 or seven secons. I then place the battery back in and the power back to the mother board and back to the rear of my computer. I then try to turn my computer back on but the same thing happens. I even did this by using the same procecures and lettint the battery out alll night and trying the same procedures in the morning, same results. Can you help.


Thanks

Frank

Time to replace the cmos battery

you must replace the cmos battery on the motherboard.

I tried 3 or four different batteries. They all do the same thing
