3 amber / 1 white is a "CMOS Battery Failure". (Source: https://www.dell.com/support/kbdoc/en-uk/000127927/a-reference-guide-for-latitude-notebook-and-tablet-diagnostic-indicators ) Did you reconfigure the BIOS after replacing the CMOS battery - date/time, etc? If the battery has been replaced with a compatible model and still does not work, there may be a motherboard fault. Can you try a BIOS update and test again with the new battery? Enter your laptops service tag here to check the warranty status - https://www.dell.com/support/home/en-uk If it is still covered by a Dell warranty, I would recommend opening a support case with them to see if they can issue a repair. Hope this helps! More on reddit.com

Did you use a brand new CMOS battery that you purchased or one that you had sitting around? Also which cable did you unplug and then 'put it back'? Make sure the CMOS battery is secure in the holder and is right side up (you should see the + on the battery facing up). Also when you replaced the battery did you leave the battery out of the holder for 15 minutes before inserting the new battery? Of course since the system worked fine before you cleaned it out then the possibility exists that you could have affected the MB such as a loose RAM module, a short on the MB, or bent the CMOS battery holder contacts.

new CMOS battery? Ans: Not new CMOS, but check with multimeter and it works fine. Also which cable did you unplug and then 'put it back'? Ans: cable between fan and motherboard; SSD; battery to motherboard. Make sure the CMOS battery is secure in the holder and is right side up (you should see the + on the battery facing up). Ans: Yes, the + side is facing up. Also when you replaced the battery did you leave the battery out of the holder for 15 minutes before inserting the new battery? Ans: For CMOS battery, yes. After the 15 min, put all the things back, and charge the power adapter again, the laptop goes 3 Yellow 1 white again to give a feedback for few time. Then, power light and the laptop turn off again. Put the power adapter again and the power light only turn on a few second without any signal again.
