Hi everyone, I am currently working on my friends HP Pavilion DV2415nr and I'm in a world of trouble if I can't fix it.

At first, the computer would randomly blackout and require a restart which cleared the issue. I ruled out software issues and thought that it had to be loose RAM.

I went in and took out and reseated the RAM. I then started it up and one RAM stick was not registering so I went in again and reseated the RAM. Now, the comptuter will power on but nothing will appear on the screen. I have tried every combination of inserting one RAM and not the other and made sure that they were inserted fully but every restart after that was the same where the computer would power on with no beeps but nothing showing up on the screen. It sounds like it can access the hard drive just fine, and the dvd drive still opens.

Any suggestions?

>>>Any suggestions?
Nothing you're going to like. No beeps means you're not posting. That is a rather serious issue. Suggestions range from a defective PSU, BIOS, or mobo. What you might try for starters is another matching PSU that U know is working.

try using another RAM check if it will help

Now it will turn on (phew!) but only after a few tries. When it does turn on, it has no problems at all, and does not show any problems on any diagnostics. Now what?

U can try cleaning the RAM slot w/some very fine rouge cloth.

I am facing exactly the same problem with my dv2415nr pavilion.

I solved the problem once, by removing the RAM slot and waiting a few days, but now, 1 month later, the notebook does not boot anymore.

I already tried to clean the RAM´s, HD, etc, and nothing... it just turns on but the screen keeps black.

I have that notebook since 7 months... did you find any solution for that?

Check for bulging or leaking capacitors on the MOBO. If they are leaking there will be a brownish tint on top like rust....

I dont know if you are still having this issue. We are having exact same issue w exact same model HP. Have had to send to HP to replace parts (probably motherboard) I suggest you do the same unless you have already taken care of it, and if so, what did you do?

i had the same problem today. Just curious . . . did you guys upgrade your ram? I'm having mine sent out, but before i do send it out to HP for repairs, I replaced the upgraded ram with the original, so HP doesn't say that it was a non hp product that caused my laptop not to boot up. This is pretty annoying. It has been 18 days since the last response . . . were you guys successful in resolving this annoying issue?

sent it away came back once (they only fixed 2 of the 3 issues) and the ac adapter is having issues now so we are sending it back again. it was a motherboard issue nothing to do with your upgraded ram but still a great idea to remove it before you send it to hp, you would probably have never have seen that ram again...
