I guess I have to bring it to a service center. Problem with that:
1: official service centers = will take weeks
2: expensive
When all I need is to clean the laptop, and potentially replace the disk. (Well, not potentially, really need to replace it.)
If I bring it to unofficial service "services": I can't be sure they won't make it worse.

Also, if I end up replacing the disk, are laptop disks easy to acquire? Compatible with any laptop models? I mean, for desktops, you can just use any disks, it's the cable and slots you have to worry about.
