ACER Travelmate 290 stops at system boot?

i have ACER travelmate 290 laptop which is really old. specs : 1.4 Intel Centrino, 512MB ram.

Recently i broke the one of hinges of the laptop and the monitor went blank. So i want to service it may be put some super glue and use a Drill bit and a quick fix for the hinge. The Broken hinge is the not the problem it's a blank monitor and now another problem. When i boot the laptop i could hear the Hard drive starts and see all the lights blink then suddenly the hard drive turns off and the system goes to a hibernate like mode at the system boot. I've changed the Hard drive still the issue exists.

Since i have a blank monitor, i've tried to plugin to external monitor using the External monitor plugin at the back, but still no image.

How do i fix this, Does this have something to do with the Broken Hinge or is it a Motherboard issue to behave like this?

here is the image of the broken Hinge:

Here is a video of what's happenning at system start, YouTube - ‪Video0012‬‏ notice the far panel of lights flashes when power comes and power stays on but i cannot see the Hard drive LED flashes, this is becuase the system goes to teh sudden Hybernation at system boot



thanks
