It tells you what model it is right on the laptop, right hand side just below the screen.

no there is no mention of HP Laptop Model on the right hand side below the screen

As we said, type 'system information' in the search bar.

Use the snipping tool to create pictures or paint, then upload them by choosing Go Advanced in your reply, (not post quick reply) then click the paperclip icon to insert a picture in your reply.

Not sure how else to help you with this.

there is no system information available on win8
