This one is a puzzle, to me at least.The display on the HP Pavilion DV2 1003AX isn't working. It's completely dead, no hint of any electrical whatever there. But I can hear the HDD running, and the indicator HDD lights are on and bright. The WiFi is also on, and the laptop gets a little warm, as per usual. One could say, it is humming along.
What I tried:
- 1st, I checked all the cables. They were all in place.
- 2nd, an external display via HDMI. No joy. And this suggested to me, the problem was on the Mobo.
- 3rd, because there's no discrete GPU, which could be replaced and the CPU is soldered, I replaced the mobo, with the 1030ES model. It fit physically perfectly, but has no native HDMI, just VGA.
- I connected the laptop with an RJ45 to my modem, hoping it would show up with an IP address. I navigated on my main computer with 192.168.x.x. to my modems DCHP page. Physically disconnecting and reconnecting the laptop did not alter the list of devices there, which could mean Windows simply doesn't boot up. Or that the laptop is beyond repair.
The very annoying puzzle is that the external displays (two TVs and a 24 inch display) also don't work ("no signal"), which tells me that the problem is not the native display. But since I replaced the entire motherboard, with the exact same result, it tells me it cannot be the cpu/gpu neither.And, not being able to see ANYthing, makes it hard to take meaningful action.
Now, I am out of ideas.
I could have had the incredible bad luck that the new mobo had the exact same broken GPU, but that seems unlikely given that the laptop is running, which indicates that at the very least both CPU's are working. Yes, it was a cheap replacement from Ebay, but still.
Question:What should be my next step? (Aside from chucking it ;-) )
I would appreciate if your answers focus on finding out what would cause even an external monitor to get no signal, rather than well-intentioned remarks about the native display.EDIT:I forgot to say that I used a boot-disk too.... nothing.
