HP Pavilion shows a blank screen with the caps lock blinking three times slow and two times fast

[Jrivas]

Hey all,

My Pavilion Notebook was working fine until yesterday when I was greeted by a blank screen with no way to get it to boot up correctly. The caps lock blinks 3 times slow and 2 times fast. I've tried going to the BIOS screen but to no avail (Which key helps me get to the BIOS screen? I've been pressing F10 but nothing happens). I've tried using a USB drive to grab the BIOS recovery tool from a different computer and use it on mine but it didn't work either.

If anyone can tell me what the problem is and how to fix it, I'd appreciate it. My Pavilion Notebook's model number is 15-au023cl.

Thank you for posting on HP Support Community.

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

Firstly, let's reseat the hard drive and memory.

1. Press and hold the Power button for 5 - 15 seconds to turn off the computer.

2. Disconnect the power cable.

3. If your notebook model features a removable battery, remove the battery.

4. Disconnect and reconnect the internal hard drive and Memory. For instructions, see the Maintenance and Service Guide for your notebook model. Locate these in the User Guides section of your notebook product page on the HP Customer Support website.

5. After connecting the hard drive and reassembling the computer, try to start the computer normally.

If reseating the hard drive and memory does not resolve the problem, try replacing the memory modules. You might also consider contacting support for repair due to a possible RAM or system board failure. HP Support can be reached by clicking on the following link: www.hp.com/contacthp/
