I have issue with my Dell Inspiron 3520 Laptop.
When i power it on i see all lights on board, and hear hdd spinning but no POST, only black screen.
When i first time disassembled it i heard 3 beeps. On Dell web page it says that is Motherboard failure.
Then i unplugged all cables from motherboard, removed the battery , ram sticks, put it all together again and no more beeps. Tried to start it again , bam Black screen again. So i unplugged my power cord from laptop, take out the dead battery restarted cmos(removed battery) changed ram positions powered it on and i saw Dell logo, i could enter Bios, and i booted Windows 10 without any problems, it can work all the time without any issue, i can restart it and all, but if i go Shutdown, it bricks again. I don't know if Windows throws the laptop in some bricked state after shutdown, i don't have more will to repair this junk. Please help me!

Sounds like intermittent motherboard failure - or possibly a firmware problem. If there's any way for you to flash the BIOS outside of Windows (if you can get the computer to start with a picture again), try that - just know that flashing the BIOS is risky! (If it goes badly, the computer won't boot... again).

Whatever you try, I think it's best to back up any data you need, just in case the failure becomes consistent and non-repairable.

Yeah i found out on some website that Dell don't have full support for Windows 10. And after i go shutdown it goes to some bricked state. So on that forum it said that i need to update firmware to last version because dell made some mistake in firmware. After i flashed to latest bios, its working like charm. Thanks for the help anyway! ;) :) Best regards!
