Lately the screen of my laptop remains black. I screwed it up and started it. You hear the hard drive start up and the fan rotates for about 1-2 seconds. Then the fan stops spinning and the hard drive stops working after about 10 seconds. Then only the light that the laptop is switched on shines. But the screen stays black throughout the process.
Now I have two questions:
Can I start a laptop without a hard disk? So should at least a picture come? If so, then I also tried that, but the screen remained black.
Do you have any idea what the mistake could be? All ideas desired.
I know it's not much information, but I figured this might be related to a virus or something similar. Does a new hard disk help?
Try it by taking the Bios battery and the battery out and then unboot the notebook then wait a good 10min wait then it could go
Does not sound good. It can be anything, but probably not a virus.
At best, it is overheating. Check the vents.
Yes, you can start without a hard disk. Boats from USB or DVD.
The notebook does not need HDD or DVD drives to boot… You even build this hardware to test a notebook to exclude these components as a source of error.
You could connect to the notebook still an external monitor and see if then a picture comes.
The CPU fan only briefly is almost normal, this is the function control (Rutine) to see if the fan goes, this remains off until the temperature is so high that the fan goes back on.
If nothing works, there's probably a defect that can hardly be remedied by remote diagnostics.
