Cannot boot up, caps lock flashes, is this a RAM failure?

[Anon6]

I have a HP 1000-1b09AU that can not start, caps lock flashes, and display blank. But before i tried to use its DDR3 memory (1,28 V) module in another laptop (ASUS A42F) with higher voltage (1,5 V). Is this really a RAM failure or is there anything else i can check / repair? Before i did this mistake i checked that all DDR3 (including DDR3L) should pass a JEDEC standard (1,5 V), but why this could happen?

Thank you.

Hi @Anon6,

Thanks for visiting the HP community. 🙂 A very good day to you! 🙂 I read the post regarding issues with the computer not booting to windows with a flashing capslock key. I will be delighted to assist you here. 🙂You’ve done an excellent job on diagnosing the issue from your end. Superb effort and spectacular research were done as well. 🙂 Kudos to you on that score. 🙂

For better clarity and to assist you better I would require more information regarding this:

• Did this happen after a bios update?
• Did it occur after a recent power outage or surge?

It definitely looks like a hardware issue with the computer.

For now please perform these steps:

• Please perform a hard reset from this link: http://support.hp.com/us-en/document/c01684768

 and then try to power on the notebook.

• If it does not power on then please try to roll back the bios from this link: http://support.hp.com/us-en/document/c02693833
• Please ensure to try both the steps from this link. If the first method doesn’t work, download the bios for this computer from another computer to a USB flash stick and follow the steps to restore the bios using the second USB flash drive method.
• This should do the trick for you if it is only a  corrupted bios and not a component failure.
• If the issue persists, then perform all the relevant steps from this link: https://support.hp.com/us-en/product/hp-1000-1b00-notebook-pc-series/5343010/model/7049601/document/... and perform the most relevant steps that match your current situation correctly.
