I have the following symptoms with my laptop. When I press the power button it lights up and I hear the fan and a single click sound, but nothing appears on the screen and it does nothing else. To power it off, I have to hold down the power button for about 10 seconds. Things I’ve tried so far: Removed & replaced existing battery; removed & replaced existing hard drive… still nothing. Please help!
That could be memory failure. Try reconnecting the memory module, moving it into the empty slot. If both memory slots are occupied, remove modules one by one and test the laptop with each one separately.
Let’s say your laptop starts fine with the module 1 but will not start when the module 2 is installed. If that’s the case, the memory module 2 is bad and has to be replaced.
