Thank you guys for the tip,
What I have done is took out the smashed screen, and I have just disconnected it from the Motherboard, to stop the laptop from over heating and stuff..
I have run the Laptop under a test for 7 full days non/stop, running antivirus, scanners and 1 MTA Server in the background.. It hasn't seemed to over heated and the CPU was running cool, and the surface I had placed it was quite cold, but everyday I would switch the laptop's places ( without turning it off ) to an colder surface.. Only the disk had heated a little throughout them 7 days, but overall it was running quite nicely and smoothly without any problems!
Thanks for the tips guys!
