DELL Inspiron 7567, Brick, BIOS restore to Factory settings issue

[Shpic]

Hello everyone!

I have a weird situation. I'll try to explain. I bought my laptop with Linux. After half a year I decided to install Windows 10 Pro x64 (I bought it). So, I wiped everything on my HHD drive and installed W10 without any problems. For 3 years the laptop worked well, but I decided to give it to another person. I started preparation to a new user. Firstly I restored Windows to default settings with wiping all user's data, it went well with no issues. And the last point was wrong for me, I decided to restore also BIOS (1.15.0) to factory default. After I pressed the button to restore, the laptop restarted with black screen and fans was working at a full speed.

I think it stuck on restoring to factory settings because on my HDD I have no system partion prepared by Dell (I wiped it after reinstal of Linux) and also because before it I restored W10 to default with an option to delete all the user's data.

I tried to restore BIOS with Ctr+Esc function with different usb-flash drives (3.0 as well), removed all battery from the system (common battery and RTC battery), hit the power button while battery were removed for 1 minute. Nothing worked for me, the laptop still turns on with complete black screen and only fans run. (In common the Diod gives no error, it stays white and remains solid for all the time - so no any errors, but sometimes it gives CMOS error - 3 amber and 1 white)

I also tried to Flash BIOS with a programmator ("on board" without soldering), the BIOS file I took from a thread from this forum. Flashing was with no errors but still no luck, situations remains the same.

Do you have some ideas on how to solve the issue? It's very weird because before restoring to factory settings (obviously common option) I had fully working laptop.

Sorry for any mistakes in the text, English isn't my native language.

By the way. Also I tried to change BIOS battery - no luck.
The screen test (when "D" pressed before start) ends with black screen.
So, after I tried to do the screen test with AC power pluged in. It didn't run as it should run(no blue, green sreens appear). I've noticed that when test starts, the LCD turns on black (not just backlight) because I found a dead pixel on it, except that after switching off it restarts just ones and continues to work with fans on a full speed with no responce from the screen.

I would try to reprogram the bios and do me clean with bios desoldered. You can also the capslock test woth external keyboard for seeing the board post.

Thanks for your input! I really appreceate it. I will give it another chanse and I'll try to flash BIOS, as you proposed as desoldered. One question, if I'll use a bios version with clean me from this forum is that okay?
And what is the test with extrenal keyboard? Can you describe it with more details please, I tried to find it on Dell forum, but no luck.

Looking forward for your reply.

Also when you can toggle the capslock or numlock led then you know the board is posting and the problem is elsewhere

I was thinking that on my Inspiron the diagnostic LED is the led for the HDD and power (the same led). And as I mentioned before "In common the LED gives no error, it stays white and remains solid for all the time - so no any errors, but sometimes it gives CMOS error - 3 amber and 1 white"
Do you think that my Inspiron also has a possibility to give errors with caps lock/ num lock?
