Hi @samperuso1 

Welcome to the HP Support Community.

Thank you for posting your query.

The HP 255 G7’s “301 error” means the system has detected a failing drive, the SSD. Replacing the SSD with a compatible model (M.2 SATA ) will fix the issue, but you should back up your data immediately before the drive fails completely.

Before Proceeding further I would request you to perform the below step and go through the link shared.

Run HP diagnostics on startup

• Power on or restart your notebook.
• As soon as the HP logo appears, press the Esc key repeatedly (about once per second).
• A Startup Menu will appear.
• Press F2 to open System Diagnostics.
• In the menu, choose Component Tests → Storage.
• Select : Extensive Test
• Run the Test.

Thank you for your reply

I have tried all the possible fixes, nothing solves the problem, still getting the 301 error on start up.

My data is already backed up on to a flash drive just in case it goes suddenly. I will purchase the relevant SSD you

advised.

Many  thanks for confirming this, much appreciated

Many thanks

I shall order the 256 GB, SATA-3, TLC L50020-001 as you suggested.

I think my laptop is about to go any minute,  when i type some of the words are shaded out, and  certain websites

text is shaded also.

Thanks again

Hi @samperuso1,

I noticed that your laptop seems to be showing additional issues. If letters, words, or website text are appearing shaded, faded, missing, or distorted, it could indicate a display-related issue, graphics driver problem. 

To better understand the situation, could you please let me know:

• Are the shaded or missing characters visible in all applications or only on certain websites?
• Have you noticed any screen flickering, discoloration, lines, or other display abnormalities?
• If possible, could you share a photo of the issue?

In the meantime, you may try these basic steps and confirm : 

1. Update the graphics driver through HP Support Assistant or Windows Update.
2. Connect an external monitor (if available) to see if the issue appears there as well.
3. Run an HP Hardware Diagnostics display test to check for any hardware-related concerns.(Link for steps to perform the UEFI - Click here )

Kindly share the requested details when convenient, and we'll do our best to help determine the cause of the issue.

I hope this help.
