HP Pavilion does't boot - blinking (2 times) led says boot problem

[GSTLeslie]

Something went wrong...

I have a HP Pavilion Entertainment PC and suddenly didn't work, after power on the NumLock and the CapLock leds blink 2 times per 3 seconds. HP Support says it a boot problem.

I googled the net, read lot of solutions, but nothing works.

When I keep pressing Win+B keys while push power button, the notebook starts, still blank screen, still blinking led and after about 5 seconds it restart (!) itself. But I can't get the BIOS back... (Win+V doesn't work either.)

Replaced the CMOS battery, didn't solved the problem!

I tried pushing ESC / F2 / F6 / F8 while power on the machine, but nothing happened.

How can a BIOS get corrupted? How can I restore the factory BIOS (I've already downloaded from HP)?

I created a recovery pendrive with the new BIOS (and the HP Diagnostic Tool) but I can't make it work...

Could you please help me?

Sincerelly,

GSTLeslie

I reviewed your post and understand that the computer is not booting to windows and the caps lock light is blinking twice.

I’d love to help!

Awesome job on diagnosing the issue correctly and performing smart troubleshooting before posting your question on HP forums. Kudos to you on that score.

Follow the steps in the below article to restore the bios.

Hello!

Thank, you for your message, I read that and followed the links you suggested. The only problem is that the Win+B (or Win+V) combination doesn't work - as I wrote before.

I have a new HDD in the machine without the recovery partition(s), so this is why I tried to solve the problem with a USB pendrive.

But the notebook restarted itself when I press Win+B kés right after powering it on.

Maybe the pendrive I created is not correct. I tried to use the HP's recovery pendrive creator utility, but it doesn't run on a non-HP notebook. I used my other (Toshiba) notebook with Win10 on it!

Could you please help me to create a perfect pendrive to restore the BIOS?

Sincerelly, GSTLeslie

Hi!

I just viewed the video about BIOS update... Thank you!

My BIOS program different (I think it is older) from what I can see in the video.

It doesn't offer to create recovery usb, it just (want to) update the current BIOS...

I checked the downloaded .exe (sp47531.exe) file and it contains a BIOS image (I think) with the extension of .fd

instead of .bin.

I downloaded another BIOS file (sp69887.exe) and this contains the BIOS System Update Utility. I run it and

created a recovery flash drive. There are *.bin and *.s12 files in the \Hewlett-Packard\BIOS\Current folder.

Should I replace these files with my BIOS file (the 3635F13.FD file) and give it a try? 

I can't find *.bin BIOS file for my computer...

I searched for BIOS update informations/solutions for my Pavilion and I got this:

There is a newer BIOS, filename: sp48896.exe

What do you think, which file doesn't exists on HP's FTP site??! Yapp, this one!! Why?

No such file:

ftp://ftp.hp.com/pub/softpaq/sp48501-49000/sp48896.exe

But the previous and the next one is there... 😮

Sincerelly,

Hi @GSTLeslie,

I recommend you contact HP phone support to further diagnose the issue.

Here is how you can get in touch with the phone support.

Open link: www.hp.com/contacthp/

Enter Product number or select to autodetects

Scroll down to "Still need help? Complete the form to select your contact options"

Scroll down and click on HP contact options - click on Get phone number.

Good day! Take care 🙂

Cheers!

Hi!

I tried with the .fd file (on a plain USB pendrive), but the recovery proccess beeps four times - it means bad or corrupted BIOS file. So, the .fd file isn't good for this method.

As a HP Employee could you send me a link where I can find a binary dump of the BIOS I need?

Or do you (I mean HP) have recovery CDs what I can download from your site? 

I loved this notebook and don't want to throw it away...

I try to find a same notebook with original HDD, then I could (maybe) use the recovery partitions to put the correct BIOS

to my bricked machine.

I think I have to send the machine to a HP service in Hungary, maybe they could fix this BIOS problem... Maybe...

Sincerelly,

Anyway... I think the support via phone won't work, 'cause I know what to do, just I haven't got the right BIOS binary/dump file to reload! But, I'd like to say a big thank you, because of your support... 🙂
