Hi experts,
My laptop isn't working right. I will tell you the conditions and you have to help me find the way out. It used to run normally, But one day it's said "Disk repairs in progress" on startup, after waiting for almost 14 hours for repairs - no results, and restarting again- no results, I pressed the power button for almost 1 minute. After that, only the blank dark screen appeared on startup. No windows logo, no Bios menu, no nothing! I opened the laptop and cleaned the motherboard and every other port, still no progress. I bought HDMI cable and connected it to desktop screen, and it says "No Signal" I tried using Fn+f4/f5, Windows +P combinations as well but no use. What can be done now?
*note: I regularly used to force shut down my laptop, by long pressing the power button.
*Model : Dell inspiron 15R i5-4gb-750gb.
