That would leave a dying GPU (yes, they can fail in such a way as the internal screen shows no video while an external one is OK) as the cause.

If you're interested in more than the usual response to an AI bot, post the full system model number and a more complete description to the issue.

@ejn63 Thank you for follow up. Is GPU part of motherboard?

@ejn63 So are there any options other than replace motherboard or use as desktop?

Not really, no - and a system this old has so little value left, any repairs should be considered in light of that.

@ejn63 Thanks again.
I've milked this along for a while. 16 yrs in computer years is like 80 human years. It really disliked W10 since it only has 3G Ram (Maxed out). It got another reprieve with an SSD transplant. Only reason I even keep it is that it runs a specific piece of software that absolutely won't install on new W10 devices, even in W7 emulation mode, but managed to survive 7 to 10 upgrade. The publisher of the software (Vanguard Brokerage Services) withdrew it years ago and does not support.

Hello again. I am having a hard time understanding where the failure is. If the GPU is failing, why do I still have a normally functioning external monitor? The BIST demonstrates that the laptop screen is also OK and connecting to something. So the GPU isn't connection to the laptop screen.
Is there some obscure command that I accidentally hit that is turning off the screen?

If the screen works through the diagnostics, it's OK, as is the cover switch.
The circuitry on the GPU chip that drives the internal display has been worked hard for 15 years -- unless the system has been driving an external monitor for the same time, the circuitry that drives the external display has not.
If you must use this model, you can find used 1535s for $20-50 on EBay, complete and working.

@ejn63 As usual, I appreciate your follow up. It sounds like you're saying that the functions for driving the internal and external display are separate on the GPU. Never occurred to me.
I'm surprised that they are still being sold, considering their limitations, even fully restored. Under what circumstance would they be used? For me this is just to run one program.
