3 Long beeps 3 LED blinks on Caps Lock key w/black screen

HP 15
Microsoft Windows 10 (64-bit)

Hello everyone.  I'm attempting to help diagnose my sister-n-laws HP 15 laptop.  I've searched high and low for an answer but all I'm finding is people with different types of "3 beeps".  They either have 3 "short" beeps or 1 short with 2 long or something like that.  I can't find ANYTHING with 3 long beeps.  It does 3 long beeps twice and then nothing.  I can hear the hard drive spinning too. No HP or BIOS documentation ever mentions anything about 3 long beeps either.  Does anyone have any idea what is going on with this thing?

 

I'm saying "3 beeps" but there's a total of 9.  However, these 9 are segmented into 3 definite sets.  It's 3 long beeps then a pause for 2-3 seconds then 3 long beeps, pause, 3 long beeps.  Total of 9 beeps.

Hello jdguthrie and welcome to the forum!

 

Depending on the type of BIOS that you have, the three beeps could indicate that there is a RAM failure. Have you tested your RAM stick? If you have another one, you might need to replace it, but only do that if your laptop is out of warranty. Any manipulation of the laptop's integrity could void the warranty. If you have the option, I suggest you to take the RAM out and substitute it if you have another memory. Some people clean the stick with a rubber, but I really doubt that it could be so helpful. I think, you need to consult the RAM's manufacturer web site how to handle this.

 

Hope I gave you an idea.

Tested that. Swapped with 2 other modules. No Bueno. Sometimes I can finally good (in a rare blue moon) and I was able to run diagnostic then and it comes up with nothing. So I boot into windows and ran some virus scans (it has those issues as well) then I immediately reboot and I'm back to the beeps. Now for two days. Other times it won't beep but just show a black screen and the. All of a sudden the processor fan gets into over drive. Sounds like the laptop is going to take off.

I hope you enjoy your visit to the HP Support Forums. I understand you are having an issue with the computer not booting and get 3 beeps. I will be glad to help you.

 

Per the document Computer Does Not Start and Emits an LED or Beep Code, 3 beeps is a Memory Module error not functional.

 

Please run the BIOS Memory Test.

Remove the re-seat the memory.

Pressing F2 to get into diagnostics doesn't work but on the rare occassions.  I just goes straight to beeping 99% of the time.  On the rare occassion I can get in I have run diagnostics multiple times.  Everything checks out.  I have reseated memory modules and replaced them.  Nothing has changed.
