Capslock Beep : error "The embedded controller times out waiting for the BIOS."

[acohen612]

Hi,

I recently bought a used laptop, but when I power it on the caps lock flashes (sometimes) 5 times (slowly) then 3 times (fast) and after that it goes (always) on 3 times (slowly) then 2 times (fast). I found out this is a "The embedded controller times out waiting for the BIOS." error and "The embedded controller times out waiting for BIOS to return from memory initialization." error, and was wondering if there's any way for me to fix it.

PS : I already tried to reseating the memory modules in the notebook and cleaning inside the notebook.

Hi@acohen612,

Welcome to the HP Support Community!

We reviewed your post and I understand that the  Notebook is not Powering ON,

Don’t worry, I assure you I will try my best to get this sorted.

I recommend you follow the below steps and check if it helps

Do you see a light at the place where the charger connects to the laptop? If yes then it indicates that the charger is all fine.

I recommend you to perform the following steps to isolate the issue and arrive at a fix: 

• Remove the battery out. If the battery is integrated and does not have a latch to release it then leave the battery inside the laptop.
• Disconnected AC adapter from the laptop.
• Press and hold the power button for 15 seconds.
• Reconnect the battery and plug the AC adapter.

F6 + Power Button

• CMOS Rest ( combination of windows button and letter 'V' then push the power button ones and release the windows and letter 'V' after 5sec

If the laptop does not power on then please continue with the below steps:

• Disconnect the charger and remove the battery out.
• Connect only the battery and check if the laptop powers on.
• Likewise, remove the battery out (if removal battery ) and connect only the charger, and check if that helps.

Hope this helps! Keep me posted.

Thanks for your reply,

I have just followed the different steps that you mentioned, but I still have a black screen and capslock beeps.

I tried the CMOS reset ( i didn't understand the sentence with "F6 + Power Button" ) but Windows + B or Windows + V commands didn't work (Windows + B seems to be better because the PC restart by its own)

Have you other solutions ?

Hi@acohen612

You have done the basic troubleshooting as per the document and the notebook needs to check to get to know its hardware is faulty, not a software issue.

I'd suggest you contact HP in your region regarding the service options for your computer or HP Chat Support Team.
