Nothing in the bottom?

No, when you press boot options a pop up screen appears with the four options listed.

How old is this laptop?

Don't know the costumer only left it with us, didn't come to think of asking the age.

But I think it was launched around the summer of 2015.

Looking at the usual causes and the description, booting from cd/dvd problem, it looks like the BIOS is causing the problem.

Well I can try to look for a BIOS update or flash it. I have to see what my boss is going to say, I mean the costumer also said that she won't mind if all data is lost.

axe0,

do you think a broken CMOS battery might cause this much trouble?

because at every boot-up I have to put in the time and date.

The time/date problem is 1 of the symptoms that the/a cause is the cmos battery.

Mmm a cause, damn it. My boss just laughed and said that he hopes it is the battery and not the circuit. :)

Yes 'a' cause, it is not for certain if there are more causes

It usually is the battery, but no garantee from my side.

Did a complete dis-assembly only to realize that there was no battery to be seen anywhere.. meh :/
