Re: DELL XPS 9550 bios dumps

Hello everyone,
I have XPS15 9550 and after I came back from vacation it suddenly won't turn on anymore. LCD diagnostics test passed. Upon power button, fans don't start and power light dies shortly after. After reading posts online, looks like my BIOS needs to be updated/ upgraded. How can I do with a USB (FAT 32) if my computer doesn't even turn on? Any help is much appreciated!

Re: DELL XPS 9550 bios dumps

Hello.
I have a big problem with xps 15 9550.
The laptop turned on, but after installing the system (each), when trying to install anything, it displayed a message that the system administrator does not allow installation. The worst thing is that no system saw wifi, despite the fact that wifi was visible in the bios. When trying to install the drivers, of course, a message was displayed that the system administrator does not allow ...
I tried ways with the system to get around this problem - nothing helped.
My service came to the conclusion that the previous owner had somehow secured the laptop and decided to program the bios from the beginning - all 3 pieces.
Unfortunately, they did not remove the bios battery while working with the bios readout. In addition, it is not known whether they correctly saved the original 16mb bios. And of course 4mb and 1mb.
At the moment, the laptop turns on, does not go through POST and turns off after 5 seconds.
I've already tried with a dozen bios - none of them worked. It's always the same - Post doesn't pass and turns off after 5 seconds. Programs each of the 3 bios. Also with the original one, it is not known whether it is correctly written.
Can anyone, anyone, help me? I've already lost hope that the laptop will come back to life.

Re: DELL XPS 9550 bios dumps

The last letters do not matter, but I am not sure about the FV replaced by BV. Try it, check chip schematics for leg inputs/outputs, I'm pretty sure they match. Here are the leg pinouts for wson, the soic are the same.

Thank you very much for your help. really appreciated

Re: DELL XPS 9550 bios dumps

Do you have your original dump? I've extracted bios file from Dell bios update exe-s on newer models and merged them with original dump. Thus far I have only needed to program the 16MB EEPROMs.

Hi. By any chance can you please give a reference of the eemprom chip you programed with the 16mb file? i have a pc but someone removed the eemprom chip and i have no ideea with ehat kind of chip to replace it. the ones I have tryed are just 8mb so are to small for the 16mb file. please help.

Re: DELL XPS 9550 bios dumps

Hi. My 9550 powers on but has a black screen though it can go to display test mode (power on + d). I tried to clean ME and reflash the bios but it did not work. Can anyone help me with the bios? And if possible, can you explain briefly how to fix the bios while keeping the system serial and keys? Thanks

Never mind. It did work. I didn't detach the CMOS battery. Unplug it and let the laptop restart a few times do the trick. The DMI info lies in the padding of the BIOS region.
