Samsung NP700Z laptop
Windows 7 Home
So, a while ago this laptop slid off a chair onto the floor and cracked the back case and the main board/keyboard/palm-rest part.... The screen was fine.
It worked fine but opening and closing the lid put a lot of stress on the hinge area which was broken in places.
The battery was old and useless too, so I decided I would replace the battery, the keyboard part and the back case.
Found the correct parts on eBay, and followed a few YouTube videos.
It was actually pretty straight-forward, put it back together.. and powered up.
The fans were spinning but not the hard-drive as far as I could tell. Black screen. Nothing.
I went and bought an enclosure and tested the drive with my other laptop - it could read it and I backed up the files just in case.
So...... the drive works, the power is powering the fans and power light.. but the hard drive doesn't seem to work anymore in the old laptop.
I've tried few fixes like holding the power button down for a minute unplugged, using mains power only, trying to attach a monitor to see if it's the laptop screen - nothing works so far.
It just doesn't sound or feel like the laptop is powering up at all when in the old laptop now.
I even tried putting it all back onto the old keyboard part but got the same result - this leads me to suspect I might have damaged the motherboard somehow.
Any ideas guys? My first post here, so thanks........
