How to order 2-in-1 laptop out of tablet mode?

Hi all,

I have a 2-in-1 laptop (Dell 7779) running F35 Workstation with GNOME. The touchscreen can fold all the way around to turn the computer into a silly-looking 17-inch tablet. When I do that, the built-in keyboard and mouse are, appropriately, disabled, except for brightness-related keys. However, sometimes the same thing happens after I close and re-open the lid, perhaps because of some fault in the hinge sensors. I’m left trying to use the on-screen keyboard to save work, close a bunch of vim instances, etc. so I can reboot and get the keyboard working. This is tricky because the on-screen keyboard doesn’t have all the special and modifier keys.

Is there some command I can issue to order the computer out of tablet mode instead of working through the on-screen keyboard?

(This is not a new issue; I’ve had this computer about five years and it’s happened the whole time. I’ve just been too lazy to make this post.)

There are new security updates for the bios (9.Nov.) Did you check this out?

Thanks; I didn’t know about that update; I’m still on the previous version. None of several years of BIOS updates have made a difference, so I can’t say I’m optimistic, but I’ll install it next time I reboot.
