Go to p.31 to view the procedure to remove the memory module.
After removing it, carefully reinsert it and reverse the procedure to reassemble the laptop and check if it turns on OK or not.
If it is still not turning on and you get the same error code you may have a faulty memory module. The part numbers for the modules are shown at the top of p.31. Search online for the part number, to find suppliers that suit you best.

Here's a [link|https://support.hp.com/us-en/document/ish_1997719-1528356-16|link] that shows what to try.

Click on ''Identify the notebook light or beep code'' and then click on ''the red light blinks 3 times then two short white lights blink (3 long red, 2 short white)''

If you have more than 1 memory module try using just one and check if it works OK, if not remove it (as per the instructions) and then try the other. The manual linked above will help as well
