Hi Folks,
I bought this computer a couple of weeks ago with the following parts missing: RAM, HD Wireless and CPU fan. So i put a WD black SN750, 32GB of Crucial RAM (CT16G4SFRA32A) and took an intel 9260NGW i had in a drawer. Unfortunately after i finished assembling everything, i booted the computer but got no image either on the computer screen nor using the hdmi output. I started removing all the parts (battery, ram, hard drive, wifi card) one by one and all together at the end, but it didn't change anything in neither cases: the laptop boots, the led (orange) of F5 and F11 keys are on and the F10 led blinks a couple of times before the fan start blowing like crazy. On battery, the same happens.
Would you guys have any idea on what those signs might mean ? Are those typical of any kind of well known hardware problem ? What scares me is that i have no image.
Any help on diagnosing the source of the problem would be greatly appreciated.
Nico

DDR4-3200 memory where the laptop is designed for DDR4-2400....which processor do you have? DDR4-3200 should theoretically work but the laptop is not really designed for it. The laptop is behaving as if it is non-compatible memory although it can also behave that way with a bad motherboard.

Hi Huffer,
the cpu is an i5 8265u.
BTW, i paid closer attention to the blinkings:
I get Caps lock num lock blinking 5 times with the ram modules
and 4 times without ram.
According to this document:
- 4 times means graphic controller not functional and
- 5 times general system board failure
- 3 times memory module error
But the HP Pavilion dv5000 Notebook PC series support documentation says the same.
Can you confirm that those code are standard for all models ?
Thanks in advance

I'm coming back to this thread, as i'm exploring various options. I'm considering swapping the motherboard. I found for about 200 bucks a motherboard which is said to be compatible with HP ProBook 440 G6 /450 G6. The part nbr is L44887-001. Looking at the pictures it looks very similar to my original motherboard which part number is L44889-601.
It looks like this motherboard is for 450 G6, right ? As both computers look very similar, i woundering whether it would be compatible with my 440 G6.
When i asked the seller, he pointed me to the 440 G6 model, which is was selling for almost 500 bucks...
Thanks

That one is listed in the Manual:
Intel Pentium 5405U processor L44887-xxx
Its a budget Pentium processor. A whole used laptop with that processor would be worth not much more than the asking price for that motherboard. Should be more like $100 to make economic sense.
