Laptop screen (D630) displays double, split horizontally- in BIOS & Windows

[tankman1989]

I tried searching for some links to this but this problem has only seemed to be an issue within Windows and in the BIOS.

When I get into Windows, the graphics display is a generic PNP 13mb adapter. I'm guessing this means that the video adapter went bad? If this is so, how can that happen with the machine just sitting there. Powered on - fine - hibernate/sleep -> bad

I guess the only thing to do is replace the mainboard on this machine if it is the video card.

I also plugged in an exterrnal LCD monitor and nothing came up.

I had a D630 come in a few months ago that was doing the exact same thing. I can't find the photo of the split screen but after it did that for a while, it started doing this...

That's supposed to be the Recovery Screen. It progressively got worst. However, I was able to get an image on an external but it looked the same. So, I told the customer he was looking at a mobo replacement and advised against it considering the age of the laptop.

On the second pic -

Believe it or not, I had bad memory cause a very similar issue. To the OP, just for kicks I would swap out mem. sticks - you might get lucky.

First thing I would check would be RAM, second, I would try external outout. If its the same on both, chances are, its the graphics processor

I would suggest checking RAM first if that does not solve the issue then I would suggest reflowing the video chipset.

You've got to connect to and external and see what the output is there. That should be the first step when the internal LCD doesn't function correctly. As someone else mentioned the RAM can cause that, rare but I have seen that too. Once you rule out the RAM the external test should determine what to do next.

I believe that the D620, and D630 are prone to GPU failure as well. So quite possibly its the motherboard.

Yes if the laptop has a Nvidia GPU, then they are prone to fail. Google it, this was a very widespread issue.

I have had some success with older nvidia GPU repair. Normally I Recommend the customer purchase a new machine. If for some reason the customer insist on a repair these are the steps I take.

1.reflow or reball the gpu
2.replace thermal pad with copper shim
3.use a high quality thermal compound
4.flash custom bios with higher default fan speeds

It's a GPU failure, I have a couple of them in my basement now.

Can you elaborate where you get the custom bios' from and what you use to load it up, I have one in that I may need to try this on.

for most of the dv*** line hp released bios with an increased fan speed below is an example for dv9392ea

as for creating custom bios its not really an easy task check the link below for general bios modding info

//edit: you could also try a simple software solution called speedfan but it isnt compatible with all machines
