I tried to upgrade the memory on my laptop today. I have done this many times on other laptops without any problems including a Dell on the same afternoon.
I put in the new 4GB RAM and put it all back together. Absolutely dead, not a flicker of life. I took the new RAM out and put the original back in and still nothing. The blue power light at the side comes on and there is a bit of noise as if the hard disk is trying to start but the screen remains black. I have tried using a paperclip on the reset button underneath but that just shuts down the machine completely.
All 12 screws are back in place and the casing sits correctly so I am baffled by it.
Any assistance would be helpful
