Can you try an external monitor?  Did it update a video driver?  Can to get to the bios screen and can you get to the dell diagnostic?

Try an external monitor first. Your display might be dead. …Odd that you got a BSOD to set that off though.


AMD or NVIDIA GPU? If NVIDIA, and you had Optimus disabled, enable Optimus and see if it works. You can do that by removing the bottom panel and unplugging the coin cell battery to reset the BIOS settings.

thank you for your help guys. it was pretty late when i posted. and kind of worried. i was very sad.

 

So it end up fixed.... i open the top part removed the keyboard.. and moved the display connector ( dont remember the name right now)

and i got image.. am writing this on m4600. i had it open to blow some air to remove dust. i believe i damaged or had bad connection. when i inserted back keyboard on to laptop there are some hinges   or tabs  (i believe is the right word. dont even know what is called in spanish and do not wish to look it up online) on top that gets inserted in the plastic and bottom has tiny screws.. probably i placed the keyboard to steep and hit the monitor cable  cause you got to put it at a angle and then pres bottom part down 

so should i get the cable.?

dont know that fix it i removed the connector from motherboard the reconnect. and i also down the black part from the picture wich is the ribbon cable.

 

 

now i faced another problem.. i could not install  nvidia driver.  very strange situation..

removing the cmos battery reset the settings so SSD needs to be AHCI and it was on raid. if i change i need to clean install.

tried the same driver i have always use. it didnt install... but i click on update deriver  and it downloaded a driver and got installed already tried a game and it runned.

could the driver i use be corrupted.?

since settings got reset omn bios i also disabled some settings wich i think i dont need.  i do remember disable wwan and anything that says dock am not using a dock so...
