How to bridge the battery on a laptop if it is in a black film?

Answer 1

Judging by the photo in the comments, the 2032 tablet on your laptop is connected via a connector. In no case should the tablet itself be jumpered (you simply spray the electricity contained in it with this action), but you need to pull out this connector and bridge those contacts of the counterpart of this connector that remained on the motherboard. This will remove the charge of the capacitors connected there, and the settings in the BIOS Setup will be reset to default. After that, the tablet must be connected as it was.
By the way, about the black film. Do not be afraid to tear it off (well, for example, to see the type of pill). If you have torn off the film or it has been damaged, it can be easily replaced with a couple of turns of a fairly wide electrical tape, adhesive tape, or a large-diameter heat shrink tube stub (with subsequent heat shrinkage).
