The CMOS checksum error occurs when the CMOS battery is worn out and the CMOS data gets corrupted. Replace the CMOS battery, this battery most likely a CR2032 lithium coin size button battery - check to make sure before you purchase.

After replacing with a new battery, then go to the BIOS configuration and set the Time & Date etc.
Clearing the CMOS (BIOS setting storage) will clear the password. Go to the Dell website and look for directions on how to clear the CMOS, or just removing the button cell batter for a few minutes, with the computer unplugged, should also clear it.
Hi, This is do with a device failure it can be the RAM of your system , Try swapping the RAM and if you find two RAM in your system remove one to check the error. Kindly send me your valuable feedback.
Hi, Always remember that when you add new hardware like a processor or faster memory you have to clear the CMOS to reset the BIOS to defaults so it will recognize the new hardware. Sometimes you have to do this with hard drives particularly SATA drives.
On the motherboard, near the motherboard battery look for a small coloured plastic jumper. If your motherboard has one it will be marked as CLR_CMOS. Just move the jumper to the other position and press the on/off button. That will clear the CMOS.
If you don't have a CMOS jumper then remove the power cord from the back of the computer and take out the BIOS battery for half an hour or so. Replace the battery and plug in power. Turn the computer on and hopefully the the computer will boot and you will see a splash/post screen. If you do remember to set the correct date and time in the BIOS utility.
If your still not getting a post screen go back and check the processor is compatible with the motherboard. Check that the processor is locked in the socket properly and also check to make sure your system memory is seated properly.
