I realize that you said that the lithium battery is OK but try a power refresh in case the BIOS has become corrupted and is preventing a normal start i.e the laptop is not passing POST (Power On Self Test)

Here’s the procedure:
***a).*** Disconnect the power from the PSU
***b).*** Open the PC and remove the coin cell RTC battery from the motherboard. Here’s the [link|https://dl.dell.com/topicspdf/optiplex-9010_owners-manual_en-us.pdf|owner manual] for the PC that will help. Go to p.13 to view the procedure to remove the coin cell battery.
***c).*** ''Press and hold the PC Power On/Off button for a full 30 seconds and then release''. This will restore the BIOS back to the factory default settings.
***d).*** Reinsert the coin cell battery .
***e)***. Reassemble the PC and reconnect the power to the PSU and check if it starts OK. There may be a message on the screen about the date and time being incorrect. This is normal as the BIOS has been reset. Once the date and time have been corrected, the message won’t appear the next time that it is started.
