That's an awesome laptop and will serve you well. A 7200RPM disk is better in terms of space then a SSD at the moment... So it should be awesome. 8GB ram is great too. It will serve you well.
One piece of advice.. Take a single piece of audio and rename that piece of audio for each track. And copy that and load a project with that, put the fader a -20 at least. Then play it back. Now repeat that untill it drops out. Now you know exactly how far you can go, trackwize. Take 2/3 off that and you're at the safe side of things. I reckon you could easily get 30 tracks 24bit 48khz. The laptop is probably with USB3. So audio can be on an external disk. And that would mean you could go up to 60/80 tracks...
I like to mix down when I reach 40 tracks. Simplifying things is creative... I've noticed.
Make sure you run that latencymon application. It will tell you if the system is stable and if things like wifi needs to be turned off or not... But I guess you'll be fine..
