So a few days ago the fan of my laptop stopped working so I tried to fix it myself. It's certainly not the first time I dissassembled a laptop, but I'm still pretty new to to it. I think I found the cause of the fan not working: There was a piece of plastic jammed in it but I got it out easily enough. But after completely assembling the laptop again it wouldn't boot anymore. To be a little more specific: The light of my charger being plugged in was burning so I suspect it's not a power problem, but when I press the power button litterally nothing happens. Not even the light around the power button itself switched on and there wasn't any sound or sign of the computer booting up. Now to get to the fan I had to dissassemble the laptop almost completely and had to take out the hard drive and DVD-drive and dissconnect the keyboard so it could be I forgot something when I assembled it but I actually think I reconnected them all. My first thought is that the hard drive isn't properly connected and that's the reason it doesn't boot, but well I'm not an expert. Reason I ask is because I don't want to dissassemble and reassemble my laptop multiple times and working with trial and error so has anyone any idea what it could be? I have an ASUS N53SX if you where wondering.
