Hi, without the model number of your Samsung laptop, remove the battery and unplug the adapter, hold the power button for a minute. Plug in the adapter and start the laptop.

Thankyou for you response ☺️ I figure out with the lock with an F inside, mybe I didn’t realize i press fnlock. I think my laptop model is from 2013. If im right the model code is NP915S3G-K01. The battery is built in.
