XPS 15 9560, 3 amber, 5 white lights blinking

Same thing happened to me last week-end, I used it Friday night, lock the screen. Monday morning I needed to print something and it never turned back on, I get the 3 amber, 5 white flash combination all the time but haven't found anything regarding the SMBIOS part. Looks like nothing is happening, I removed the battery, tried on power only, same behavior.

HI,

I also have the same issue with a XP15 9560; 5 white, 3 amber, refusing to boot (i.e. I don't even get the "DELL" splash screen and an option to enter the BIOS)

I'd had this problem pretty much since I bought the computer, but it has usually very sporadic and it goes away after an hour- recently it seems to be more frequent.

Suggestions/updates very gratefully received!!

Kind regards,

dom

1. First remove the battery, unplug the power plug, press and hold the power button for about 5 seconds, then plug in the power supply to see if it can be turned on, if it still can't be turned on, continue with the following steps.
2. Remove the battery, unplug the power plug, and use a Phillips screwdriver to open the back cover screws. There is an opening on one side of the cover. Use a screwdriver to gently lift the cover along the opening. Then you can remove the cover.
3. After removing the cover, locate the memory module, and use a screwdriver to gently open the snaps on both sides of the memory module so that the memory module can be released. Gently remove the memory module and wipe it to see if the memory module is intact. Wait a while before installing it.
4. Follow the disassembly method to cover the cover, install the battery, turn on the power button and restart.

I don't believe it's a BIOS problem. I decided to send it back for diagnostic and pay the 59$ in order to get their inputs on this problem since I paid over 2K$ 3 years ago and I am a bit pissed about this as well. Sending the unit back today and will update this post once I get their diagnostic. I expect they will propose to replace the motherboard, and/or the display board.

Hi, I also had the same problem, after 3 years of use my PC I had to disassemble to change the thermal paste, the warranty had also expired, after disassembly to disassemble the battery on the flex cable input there was the cover, I tried to unscrew but the slot was not soldered i.e. it was a production error I think, while I was unscrewing he made a short on resistances, immediately after I disassembled the battery, and changed the thermal paste, after I tried to access, I had no sign of life, when I press the power button it lights up, but the fans do not turn, and it continues to do 3 orange LEDs 5 white LEDs, I tried contacting the guarantee they told me they can make a quote but you have to pay a shipping cost of about 60 euros, I thought a little was not worth it because the minimum will require 600/800 euros which I do before to take a used one, but I wanted to solve the problem. I disassembled everything, disassembled the motherboard ssd le ram cmos battery, all disassembled kept for 2/3 hours without any connection, then I pressed for 30 seconds 10 times on the power button, after the test he had the same problem, then with the multimeter I tested all the resistors all the transistors, the capacitors, they were all working, at this point the last thing to do is to change the bios chip, I am not very expert on air soldering, for this reason, I have not touched, sincerely to this point I am looking for a solution, because I spent about 2 thousand euros 3 years ago, I believe that at least dell can share what it means 3 orange LEDs and 5 white LEDs what is needed, it does not make sense to say probably bios problem, it should say that it is a problem of bios, someone technician who can solve this type of problem? can share your experience thanks, I also tested the cmos battery is working, but pc always has the same problem, it doesn't start.

okay bro,I'm waiting for your answer, let's see if dell can repair without changing the motherboard, and what they will write on the description of the repair, in theory I know a dell technician, he doesn't know the solution to the problem, he also doesn't know what kind of problem it is, not even on dell datasheet there is no written what is 3 orange led 5 white led .... i wait your answer thanks ..

Thank you for staying connected. I'm Dibyendu, and I will be assisting you

are you hearing any beep sound ? need to  diagnosed by beep sound...

can you do this following steps:

stop system disconnect all power then open a system remove ram from both ram slot.

clean both  ram with eraser 

then connect 1 ram into the ram slot (exchange slot)then power on machine

if you seeing same thing then again disconnect all power then 2 nos of ram clean by eraser and connect another slot then check this

if you getting same things so connect your local technician....

I think xps 15 9560 has no speaker on the motherboard for the beep, however no beep sound, when I press the power button from the led on the power for 10/15 seconds then it switches off and on the battery led it continues to do 3 orange 5 white LEDs , I tried pressing the esc + ctrl key then connected to the power supply, after 3/4 seconds the power button LED lights up, then after 30 seconds it switches off then it lights up again and lights up the keyboard, but the fans do not turn.
always black screen

if it was a power problem, the power led did not work either, or the battery did not recognize, I don't think it is a power problem, most likely and a bios problem, I found the bios chip already programmed on ebay, but I am undecided to change, I would like to be sure what the problem would be, it makes no sense to say probably power.
and it does not make sense to change the motherboard, the minimum cost of the motherboard is 400/600 dollars, used of the pc is 700/900 dollars, is there a way to flashare the bios via usb? holding down the keys ctrl + esc?

I repeat, I have already tried disassembling everything I have tried to change the ram too, I have also tried with another compatible DDR4 ram, I understand you recommend going to a technician, but I am already a computer technician I know how all the technicians in my area work, the their experience is not enough to make such a repair, they say directly to change the motherboard, who is a technician knows what does 3 orange LEDs and 5 white LEDs mean? can't you give advice except change the motherboard? , all the things I tried I wrote on previous comments you can read please, thanks
