After I plug back in my Dell Inspiron 530, It turns right back on by its self and resets the CMOS also. After it turns on, it shows diskette failure. I have to go into the bios to correct the date and config after it turns back on. I think it might be the CMOS Battery. Why is my pc turning back on by it's self after I plug it back in???
 
Yeah, sounds like a problem with the CMOS battery. As for why it turns itself on, it's fairly common for a motherboard to have a BIOS option like "Restore on AC/Power Loss", and possibly your board defaults this to "Power On" instead of "Power Off".
