I didn’t want to answer this, but there is some potentially dangerous information in the previous answer you best not follow yetyet until you know if it has an SVP.

Before you do ANYTHING with the system (especially the CMOS battery), get a external display that has VGA if at all possible; it can be DVI/HDMI only, but you will need a [https://www.amazon.com/gp/product/B01274GAC8/?tag=ifixitam-20|mDP adapter like this] to get it going as the Thinkpad only has onboard VGA. We’ll get to why I want you to mess with literally anything else before the CMOS battery. It doesn’t need to be a new monitor - something used from a thrift store will work as long as it has the ports you need.
 
Removing the CMOS battery on a Thinkpad 390E-XX30 is a potentially dangerous mistake; if you can recover the ATMEL chip, you can oops it. However, it is DEADLY on the XX40-present generation with Boot Guard. If you reset the ATMEL chip using the old methods, you will lock the machine out due to tampering and need a motherboard. '''''If you removed it without being sure, this is a deadly error if you had a SVP :(. If I’m reading the previous thread right, pray it never came with a SVP.'''''
