HP Pavilion DM4 Notebook - black screen on start up

HP Pavilion DM4 Notebook PC
Microsoft Windows 10 (64-bit)

Product name: HP Pavilion DM4 Notebook PC

Product number: LS721EA#ABU 

I tihnk it is 64-Bit but I am unsure. I upgraded to Windows 10 about 4 months ago.

 

 

Hello,

 

I have an HP Pavilion DM4.

 

When I tried booting up this weekend I got a black screen with a flashing white line in the top left hand corner. In the bottom left hand corner I had a message "Press Esc Key for the Start Menu".

 

I tried a hard reset and the caps lock LED button comes on.

 

I have since run the system diagnostics test and the Start-up Test, Run-in Test, Memory Test and Tune up failed. The description for each one is Memory module. The error code is as follows:

 

Tune Up: 64RHWW-5MV85J-XD6V5G-401MO3

All others: 64RHWW-5MV85H-XD6V5G-400503

 

The hard disk abd battery tests passed.

 

I reseated the memory module but that hasn't made any difference (It was positioned correctly when I took it out)

 

Can anyone recommend what I should do next?

 

Thanks

Simon

Hello @simonjohnson,

 

Thank you for visiting the HP Support Forums! The forums are a great place where you can find solutions for your issues, with help from the community!

 

I came across your post about the issue with the notebook not starting, and wanted to help!  I understand that you tried running some tests, and getting error messages for the Memory Modules.

 

Based on the Failure IDs you provided, the Memory Modules may be defective, or not connected properly.  If you already tried reseating the Memory Modules, then you may consider replacing them.

Hi,


Thank you very much for your response.

 

Could you provide a link to a trusted seller from where I could purchase relevant memory modules in the UK?

 


Best wishes

Simon

I am unable to assist with that type of information.  However, based on the following guide, here are the spare part numbers for compatible Memory Modules:

4 GB (PC3-10600 1333 MHz) - Spare part number: 621569-001

 

You can get parts from here: HP Parts Store
