del works with NUM. lock off, if is DEL
del key is del and dot,. do not use dot key.
yours users manual covers all that, all PCs do.
no 2 are the same vast BIOS exists and version and contract versions , endless now. 40 years deep.

You download the BIOS update from here. In case you don't speak German, here's the translation:

1. Download bios7502.exe
2. Double-click the file and unzip (default is C:\Medion)
3. Go to the location where you unzipped the files and run WinFlash.exe
4. You can save you old bios (just in case) as i.e. oldbios.bin
5. Now open the new bios version with the name W7502MLN.10R and start the update process by clicking the update button.
6. Reboot and you're done.

Note: Don't run anything else when you're doing this and do not interrupt the process until the reboot is complete. You could risk rendering your BIOS unusable!

I would think that repeatably hitting F2 as you boot will get you into the bios to change setting.

Try F1.
Try F2.
Try F10.
Try F11.
Try F12.
Try ENTER.

Or, with the computer turned-off, press and hold the SPACE BAR.
Turn the computer, and keep holding until you see the "keyboard error, press <blah> to enter setup". Press the <blah> key.

The fan itself is probably the issue.

not sure whats so tricky is really rather simple the laptop must come apart there is a battery on the mother board it must be removed for aboput 10 minutes this will total clear the bios replace the battery and reassyemble laptop if that dont fix it you may need to flash the bios to repair it.

put the cmos battery back in and before you turn it on press and hold down the f2 key should send you to bios where you will have to reset all funcation becase you removed the battery

It seems u have updated wrong bios...then the motherbord need to be re programmed for the u have take it to service center........
