I have Dell laptop since 2013. few days ago, my laptop suddenly shut down & never turned ON. I have done power flee (removing battery & power cable then pressed power button for 10-12 seconds. then plugged cable & put battery in) as well as power cycle (normal turn off & turn on). I have also tried to turn on by removing bettery & plugging power cable. Still no effect. Kindly suggest any step to fix this. Thank you.
When you plug the charger into the jack, you can't hear a thing can be heard from the fan or the hard drive?
If you can't and the warranty of your laptop has expired I suggest you to take out the hard drive and try to connect it to another computer through SATA-USB cable. If the HDD doesn't spin at all, anywhere, then it has failed mechanically and needs replacement.
If your hard drive spins up on a different computer and it is recognized there, but cannot power up on your laptop, then the problem is hiding probably in the power supply unit on your motherboard. You could bring your laptop to a technician to make a test of the power connector and/or the power jack center because they might have got damaged.
Please, come and shared what happened with the tests.
