No hard drive in my HP Pavillion x360

[computer-20_20]

I took my laptop apart earlier to remove the battery and hard drive.

However on opening I can’t find the hard drive. There is a large space where I expect it’s meant to be but it’s empty.

Is there any chance the hard drive is under the motherboard? My laptop has worked fine for a number of years so I don’t see how it’s been running that whole time without a hard drive.

Attached  is a photo showing what I mean. 
The larger space is where the battery goes which I have removed but the space next to it was empty on opening. This is were I expected the hard drive to be. 

The larger space is where I have removed the battery, but the smaller space next to it had nothing in it on opening . This is where I expected the hard drive to be.

Some x360 models have hard drives; others have only SSDs.  We need to know the specific model number of your laptop.

OK, thanks -- here's the HP product page for your PC: https://support.hp.com/us-en/document/c05536232

You see that it does not have a hard drive; instead, it has a 128 GB SSD -- which is why the hard drive space is empty.
