One RAM slot not working

[JeanieandPaul]

This notebook became very unstable with frequent crashes.  After long process of troubleshooting, it seems there was an issue with the 4MB RAM slot or stick.  With that 4MB module removed and the slot empty leaving only the 8MB stick installed, the laptop is stable and runs near perfectly, except that it's down 4MB of its RAM capacity.  I can't quite determine a labeling/numbering of the two slots but with the laptop inverted and battery/hard drive on bottom and fan on upper right, the "good" slot with 8MB is on the left and the bad slot is on the right (currently empty).   I have run the updated Diagnostics with no failures noted, and BIOS are current.

I read in multiple places that RAM could be upgraded to 16MB, so I bought both 4MB and 8MB sticks.  I have tried multiple configurations with these:  8/8, 8/4, 4/8 and every time there is something/anything plugged into the right slot, the laptop throws the 3+2 light code on Caps Lock.  With the right slot empty, it boots/runs fine...in fact, this post is from that laptop.  

Any help or insight to the problem would be appreciated.  Thanks!

Hi @JeanieandPaul,

Welcome to HP Support Community.  

Thank you for posting your query, I will be glad to help you.

If one of the RAM slots in your HP ENVY x360 M6 is not working, it could be due to several reasons, and there are steps you can take to diagnose and potentially resolve the issue. Here's a step-by-step guide.

Check for Physical Damage: First, ensure that there is no physical damage to the RAM slot or the RAM module itself. Look for bent pins or any visible signs of damage.

Swap the RAM Modules: If you have two RAM modules installed, try swapping them between the working and non-working slots. This will help determine if the issue is with the RAM module itself or the slot.

Clean the RAM Slot: Sometimes, dust or debris can accumulate in the RAM slot, causing connection issues. Turn off your laptop, unplug it, and gently clean the RAM slot with compressed air or a soft brush.

Update BIOS: Ensure that your laptop's BIOS is up-to-date. Manufacturers often release BIOS updates that can improve hardware compatibility and functionality.

Reseat the RAM: Turn off your laptop, unplug it, and carefully reseat the RAM module in the non-working slot. Make sure it's properly inserted and locked into place.

Test with a Different RAM Module: If you have access to a different compatible RAM module, try installing it in the non-working slot to see if the issue persists. This will help determine if the problem is with the RAM module or the slot.

Run Diagnostic Tests: Some laptops have built-in diagnostic tools that can help identify hardware issues. Check your laptop's user manual or HP's official website for instructions on running diagnostic tests.

Remember to back up your important data before attempting any hardware troubleshooting, as there's always a slight risk of data loss when working with hardware components.

I hope this helps. 
 

Take care and have a good day.

Thank you for the response and the suggestions.  I have tried all the remedial steps such as inspecting, cleaning, and swapping, but the only configuration that works is with that slot empty.   It would be helpful to run/see diagnostics that show RAM slot functionality.  All I have ever seen is 8MB available, or 1/1 slot used.   Is there any means of running a test on the slot itself to check if the motherboard recognizes it as present, but empty?

I was having a similar issue and I ended up narrowing it down to the ddr-1 slot not working properly. What ended up working was holding the ram pushed down into the slot when powering the laptop on.
