Dell XPS M1530. It doesn't turn on

I had the exact same problem. it seems like this problem happened to a lot of M1530 owner. It usually happened a couple months after warranty. It's a motherboad problem i believe!

Try hold the "D" key while hitting the power button. That works for me last time. If not try "fn" + Power

That brought my computer back for about 2 weeks then happened again. THis time no luck so far!

If you found out anything, do share coz I know lots of people experienced that lately.

PS. I think Dell might be screwing around w. us, seems like they know this would happen after the warranty runs out. They make u purchase the extended warranty to replace the motherboard which is $500.

Alamask-
What ever became of this problem? I am in the same boat. I had the flashing num lock and no other action from computer. I replaced the mobo and it actually started up, but it went through some memory checks and before it finished it locked up. I tried to restart it, and now I get the flashing cap lock led (which indicates a memory problem?). I have reseated everything and even tried it with everything not in place. It's just off warranty and I don't want to blow alot on it if it's all in vain.

I am right there with you guys. I'm servicing a client's XPS M1530 right now and originally it started with the "no screen at all" problem. Eventually after holding the power button for 30sec with battery out and flushing the "memory" that way it came back and I got vid to at least see the BIOS. After running a Diagnostics with (FN+Power) it found a memory error. Then I reseated and switched the RAM in the DIMMS. Got into Windows in normal mode! However, now the screen dies after several min in Normal Mode. It is ONLY STABLE in SAFE MODE. Going to research for Vid driver issues.

I had the same problem, this worked for me (typing on the laptop right now):

Basically you need to somehow repair the a faulty connection between the GPU and the motherboard by overheating the GPU a bit. Didn't think it would work... it did. We'll see for how long! Good luck.

Thank you!! I was convinced that either I would be out hundreds of bucks for a mobo or in need of a new system. But I tried what you suggested - overheated the GPU until the fan ran for quite a while, then booted up, and I'm back in business  

Thanks, Bradysama, and thanks to whoever suggested this fix to you.

As bizarre as this method is, it works. Unfortunately, I have to repeat it every morning. Any suggestions?
