Recently, I'm experiencing a problem with my laptop. I have a dell latitude e6420 without a battery, It keeps on booting up automatically when plugged then prompts me to set up time&date everytime when plugged. At first i thought it was the failure of Cmos battery, I replaced the cmos battery then configured the bios but no luck so far the problem still coming up again n again. I need help with this and i also need to know if this is worrisome in the future incase more problems might arrive due to this. I hope you guys can help me out with this..
