I've got a Dell Inspiron 1150 laptop that I'm having problems with. Yesterday I turned it on and after a few minutes, my mouse froze. Restarted and freezing happened again. Restarted once more and now screen is black. When I start, I can hear the fan kick in, the front power light comes on and then about 30 seconds later, the fan winds down but the power light stays on. A few things I've tried:
- hooking up to external monitor and hitting FN +F8 to activate. No signal to external monitor.
- have removed and reseated RAM chips, removed battery, hard drive and DVD player.
-Purchased new power adapter today (old one had a faulty wire) but still no luck.
- tried connecting to machine via network when power light is on but other PC doesn't see it. So don't think it's just an LCD problem.
A few times since yesterday among the many times I've restarted it, the screen actually did come on and the machine booted. Within a minute of two though the mouse froze again and of the last 20 or 30 restarts, I have not been able to get the screen to come back on again.
Any suggestions? Or is this just sounding like I need a new motherboard?
