"CMOS Checksum Bad" Dell Laptop Computer Error with No Power
Hello,
Recently, I have been having problems with my Dell Laptop Inspiron. Here is what happens.
1. When I try to boot up, I hear the disc running and the mouse appears on the screen but the screen is completely black. It receives power supply as when I plug in the power, the Green LED lights up.
2. When I followed the procedure to trying to reset somethings by taking out the battery, holding the power button on for 10 sec. then placing it back in, the Dell Laptop begins to screech with a loud beeping every few seconds.
3. The error message then responds by saying "CMOS Checksum Bad" as well as the other error about date and time. However, I looked for this problem a little bit online but the error codes don't match to what I was receiving.
I was wondering if anyone could help me with my CMOS error because I want to make sure I don't have a virus as well as I could actually use my computer again.
Thank you for your help in advance.

Try first changing the CMOS battery. How that's done depends on the system model - we'll need to know that to point you in that direction.
If that doesn't solve the problem, the CMOS chip itself is bad - you'll need to replace the mainboard.

That's the first thing to try. If it doesn't solve the problem, the mainboard needs to be replaced.

Hi there,
Thanks for the suggestion. I will look into that.
On another note, I got the computer screen to come on and restored some of the computer's settings to work how it once had. I still have all my documents and user files but the only problem is the date and time are really messed up and I am afraid that there are some other things that are probably just as messed up as well. I believe the date and time have to do with the BIOS factor. I have seen many things where people reset their BIOS to default. Is there anything else in addition to the CMOS battery change that I could do?
Again, thank you for the help.
