    Dell Inspiron 5559 No Display

    Hello, I have above said model.
    Please help me, It turns on without no display. Every voltage supply is ok. Tried different BIOS and original clean me bios but no effect.

    Problem is it looks like display about to come, fan spins high. When I power on display goes dark without any data and backlight.

    Any help will be appreciated. Thanks.

    Original bios attached.

                  did you check DIMM SLOT
                  +0.675V DDR
                  +DDR VREF VTT
                  +1.35V MEM
                  DDR DRAMRST

                  +5VS +3VS ON U22 OK ?
                  All voltages in U5602 are ok ?
                  All voltages in U15 are ok ?

                                          Fan goes high when vcore is not present on many dell/sony.

                                              by zenius
                                              Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.

                                              Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...

                                              by The WABBIT
                                              I had recently purchased a used Dell Inspiron 5559 that I had found at a local pawn shop. And of course the system is locked. And I have no idea what the Admin pw is and I have no information for the previous owner.

                                              After many days of research I have found that this system, like many new system, require a Master PW/Code to unlock it or reprogramming of the BIOS.

                                              Contacting Dell Support was a waste of time. They won't give me the the Master PW/Code unless I have the information of the Registered owner that they have on file. They even gave me a link to a page on their...

                                              The Dell Inspiron 3480 I own (the all in one, not the laptop) is not wanting to turn on at all. It goes right to a dell logo, but it stays there forever with no other information on the screen. Holding the automatic Bios repair key combo (ctrl+esc) that should let it read a recovery file off a USB drive gets stuck on a black screen and does nothing. No amount of resetting anything so far has worked, and Dell's own support downloads have not really helped. Ive tried another BIN file I found online using my CH341A, and this got me slightly more, that time it displayed a loading bar that never moved...

                                              Hi, I hope some one has some advice for me. I searched the forums but didn't see anything relevant. I acquired two identical Dell 9010 Mid Tower computers from a business office upgrade (they were going to throw them out). Both of them have the same motherboard (00F82W). One of them works flawlessly. The other one had a corrupted BIOS. I tried flashing numerous main BIOS and EC files from the internet, but none of them worked. I decided to copy the main BIOS and EC from the working 9010 computer and successfully flashed the corrupted BIOS. This got the computer able to boot again and run norm...
