If I have created a Powerpoint and the laptop then goes out because it has no more battery, is the Powerpoint saved?

If I have created a Powerpoint and the laptop then goes out because it has no more battery, is the Powerpoint saved?

Probably stored unusable, so it could be what is missing or the PPS is not working.

If Powerpoint is automatically cached, the last save point remains

No, actually not, but the office programs from MS have a function with which the status is automatically saved, then at least part of the document remains…

It may be, it depends on whether automatic saving is set and whether there was enough time to save when shutting down.

If the Accu is older and suddenly goes flat, even the file in the memory can become corrupt
