laptop crashes at startup - unknown reason yet

My laptop crashes at start up.This only happens when:

• I start the laptop
• The power cord is disconnected (only battery)

The laptop just shuts down abruptly. The logs are corrupted and it is very difficul to know what happens. However, I compared the logs of a normal session with the logs of the crashes. I guess this might be related to bluetooth but I am not sure.

I tried deactivating bluetooth through the GUI interface, but the problem persisted.How could I completely deactivate bluetooth to make further tests? What else would you suggest to look at, might this be a power saving issue?
